South Africa has every right to take pride in its rich and unique botanical diversity. As part of investigating the discipline of botany in the country, we have assessed the contents of five botany-related South African journals in the period 19882002, analysing the sub-disciplines, affiliations of the contributors, and the age, gender and race of the first authors. The results show various trends, such as a decline in the number of articles during the 1990s and then an increase in 2001 and 2002. A specific niche for each of the five journals has been identified. These journals have adopted strategies and introduced improvements to survive change in the evolving scientific environment. Most articles are from authors in the age group 3140; men accounted for 68% of botanical papers and women 32%. Whites authored 94%, and other racial groups 6%. The botanical sciences are among the leaders in South African research publications in terms of output and citations.
Interest in South African botany has long been driven by the natural environment and rich plant diversity of the country.1 The Genera of South African Plants by W.H. Harvey is reputed to be the first botanical book printed in South Africa, in Cape Town in 1838. This was followed by increasingly formally structured research on the flora of South Africa including the documentation of families, genera and species, with inventories, identification keys, field guides, detailed monographs, regional floras and Red Data lists as records and publications. Accurate coverage of the unique flora at the species level has been made possible through PRECIS (National Herbarium, Pretoria [PRE] Computerized Information System), listing approximately 368 families and 24 000 taxa (species and infraspecific taxa).2 Interest in plant ecology has also been driven by the dynamics and composition of the natural environment, and several vegetation maps, together with numerous descriptions of vegetation types and plant communities have been generated. Plant physiologists have been presented with a vast range of subjects, examining physiological processes within this natural plant diversity. Structural elucidation of DNA and the genes that it encodes at molecular level has moved the emphasis in botanical research in wealthy countries to a molecular focus, with the consequent development of molecular biology, encompassing molecular biosystematics and biotechnology. These trends reached South Africa during the 1980s. In spite of our rich botanical diversity, core interest in the 'traditional' botanical sub-disciplines has been waning,3,12 raising concern among botanists at universities and at institutions that account for botanical research and its related services. New techniques have influenced research in all sub-disciplines of botany, emphasizing the need to keep step with advances, to be able to publish science of current relevance.
The state of botany in South Africa should be seen as part of the overall picture of the condition of science in the country. The assessment of publications can be regarded not only as a reasonable measure of scientific viability, but also as an indication of the country's research enterprise. Pouris4 has used bibliometric indicators to rate the plant and animal sciences against other disciplines such as the earth sciences, chemistry, engineering, mathematics, and clinical medicine. These showed that biology is one of the strongest and most vigorous disciplines, and that South Africa's scientific strength lay conspicuously with the life sciences.5 Pouris6 notes also that by 1989 South African performance in biology had been concentrated in the 'macro' aspects (whole organisms and ecology) but predicted that major advances in biology would come from genetics, biochemistry and molecular biology (the 'micro' aspects, that had displayed high growth and commercially exploitable results elsewhere). Current research7 indicates that publication numbers decreased in molecular biology and genetics, contradicting the National Biotechnology Strategy in 2001.
In a survey of South African research periodicals published in 2000, Pouris and Richter8 concluded that South African journals were introspective, and that their reach in terms of circulation, subscriptions and indexing was limited. Foreign citation impact was generally low, and that prominent South African scientists published significant work abroad, to the detriment of the quality and standing of our local journals. As a result, government policy led to withdrawal of state funding for national scientific journals produced by the now-defunct Bureau for Scientific Publications,9 placing the financial burden of publication on the associate publishers, usually professional scientific associations, and forcing them to adopt new strategies to survive. Moreover, South African science became affected by restructuring, as well as by organizational and cultural changes in many scientific institutions.10,11 Herbert et al.3 reported in 2001 on what they termed the crisis in capacity and resources in taxonomy and systematicsª in this country. The main factors identified in that survey and relevant to our current study are:
A long-term decline in human resource capacity. The number of taxonomists/systematists in South African museums had decreased by 35% from 1991 to 2001.
Lack of research funding: for example, National Research Foundation (NRF) grants, 38% of submissions for research projects to the 'Conservation and Management of Ecosystems and Biodiversity' focus area, were rejected in 2001.
Poor salaries in the academic sector, particularly in museums and herbaria, constitute a major financial disincentive to matriculants and graduates who might otherwise be considering a career in taxonomy or systematics.
The view that taxonomy and systematics research had reached a point where recovery and future progress were under serious threat12,13 is paradoxical. The justification for research has never been stronger than at present, and its relevance has never been greater.14 There have been numerous significant events in the botanical sciences1520 the most far-reaching being South Africa's ratification of the Rio Declaration on Environment and Development (Convention on Biological Diversity).
Procedure of the investigation
Scanning of publications
All botanical papers that appeared in the five journals surveyed, African Journal of Range & Forage Science, Bothalia, South African Journal of Botany, South African Journal of Plant and Soil and South African Journal of Science, were published between 1988 and 2002. Articles are classified in terms of the broad botanical sub-disciplines of taxonomy, ecology, physiology, biotechnology and biosystematics. Biotechnology and biosystematics have been treated as separate sub-disciplines, in order to assess the impact of the molecular sciences on botany. Institution, surname, age, gender and race of the first author are also documented. Institutions have been classified as SANBI (South African National Biodiversity Institute), university, international, government, and private. Although SANBI is a public entity in the Department of Environmental Affairs and Tourism (DEAT), we excluded it as a state department, to be able to identify the institute's separate contribution to botanical research in South Africa. Information on age, gender and race of first authors was provided by peer botanists, but in some cases the identity of authors could not be traced, this being the reason for missing data. Ages were grouped as follows: 2030, 3140, 4150, 5160 and 61+.
Journal impact factors for the years 2002 and 2003 were extracted from ISI Journal Citation Reports.21
Results and discussion
African Journal of Range & Forage Science (Afr. J. Range For. Sci.) ranks as the leading rangeland and pastoral journal in Africa. It was the Journal of the Grassland Society of Southern Africa until 1992. Three issues are published per year. The current publisher is the National Inquiry Services Centre (Pty) Ltd (NISC), in Grahamstown. Support comes from the Grassland Society of Southern Africa, with P. Scogings of the University of Zululand as its editor. The journal publishes refereed scientific papers and research notes, as well as book reviews.
This journal is linked to the sub-discipline of ecology, particularly rangeland ecology and contributed 10 to 31 papers per annum from 1988 to 2002. The number of physiology articles that appeared in it gradually declined from 1998 to 2002. It published a few taxonomy papers but none in biotechnology (Table 1).
Contributions from government institutions ranged between 2 and 21 per annum, also indicating a decline in the number of papers over the period 1997 to 2002. Foreign contributions to the journal are largely constant, with a definite increase in these submissions after 1995. Universities account for 3 to 15 articles per annum. The agricultural focus of this journal can explain the low number of articles from SANBI staff. Despite there being substantial agricultural expertise in the private sector, it does not contribute to the journal (Table 2).
The periodical has adopted the following survival strategies:
Imposition of page charges.
A focus on the discipline in an African context from 1993, when it adopted its present title. Contributions from elsewhere in Africa have subsequently increased.
The policy change was introduced when the journal had already achieved financial autonomy, and was not affected by the withdrawal of state funding for government-subsidized journals.
Afr. J. Range For. Sci. now makes use of electronic publication, with free access to its content. This arises from an agreement between NISC and the UK-based Ingenta, one of the world's largest collections of online journals.22 The benefits include enhanced international exposure and worldwide marketing.
Bothalia was first published in 1921 under the leadership of I.B. Pole Evans, then director of the Botanical Research Institute (BRI).23 It was named in honour of General Louis Botha, first prime minister of the Union of South Africa, also minister of agriculture until 1913. The BRI amalgamated with the National Botanic Gardens of South Africa (NBG) in 1989, and Bothalia became the house journal of the institute. Two parts, with indexes to contents, authors and subjects are published per year. The current scientific editor is G. Germishuizen.
The journal has a niche for papers in the sub-disciplines of taxonomy and ecology. Taxonomy papers have varied in number over the assessment period from 21 to 39, and ecology papers from 1 to11, per annum. The main focus is on taxonomy, ecology, anatomy and cytology. Although molecular biology is used as a taxonomic tool, there are very few systematics papers that have been based on molecular data, to date.
Contributions from SANBI staff have been the most numerous during our period of assessment, ranging between 11 and 32 per annum. Universities also use this journal consistently for publication, and their contribution has varied between 4 and 16 papers a year. The journal had a consistent record of 1 to 6 articles by foreign authors per annum. Other government institutions have contributed between 1 and 5 articles annually, and submissions from the private sector have been increasing. Except for a decline in number of papers in 1996, publication in Bothalia has been very consistent.
Bothalia is funded by SANBI, and has adopted the following measures to promote itself:
Imposition of page charges.
Marketing through the official SANBI website.24
Selected articles are highlighted on the institute's website.
Free indices to most volumes are available on request.
South African Journal of Botany (S. Afr. J. Bot.) was first published in June 1982, at a time when a number of national science journals were established under the auspices of the Bureau for Scientific Publications. S. Afr. J. Bot. amalgamated in 1984 with the Journal of South African Botany, which had a 50-year history as the in-house journal of the then-named NBG of South Africa. The format and name of the S. Afr. J. Bot was retained. From its inception, the S. Afr. J. Bot. was supported as the scientific mouthpiece of the South African Association of Botanists (SAAB).9,2527 S. Afr. J. Bot. was published by NISC between 2001 and 2005, and by Elsevier thereafter. Currently it is an interdisciplinary journal for plant sciences, regularly supported by foreign contributors. The editor is J. van Staden of the University of KwaZulu-Natal in Pietermaritzburg. There have been about six issues per annum until year 2000, dropping to four issues per year thereafter, until 2002.
Taxonomic contributions have been consistently dominant between 1988 and 1999, with these papers varying between 27 and 58 per annum. There was a decline from 2000 to 2002. The number of ecology papers varied between 14 and 37 per annum during the period 1988 to 1994, but there has been a marked decrease after 1995. Physiology papers have risen in number from 1998 to 2000. Although there is a trend in botany to move towards biotechnology and biosystematics, this is not evident from the papers under review. Statutory funding of S. Afr. J. Bot. was withdrawn in 2000, and a temporary decline in the number of papers arose possibly from a loss of financial support. Nevertheless, the number of papers increased again in 2001 and 2002.
The S. Afr. J. Bot. has been a favoured journal for universities, the source of 1971 papers per annum during the assessment period. The journal has regularly published papers by foreign authors: 25 in year 2001 and 10 in year 2002. Both SANBI and other government institutions contributed 1 to 13 articles per annum. Contributions by the private sector are negligible, despite sustained research in the fields of biotechnology, weed control, horticulture and plant breeding by this sector. This trend may be linked to the issue of confidentiality that is inevitably associated with research that is directed towards commercial exploitation of intellectual property.
Strategies that have been adopted by the journal:
It has consistently published papers by foreign authors, contributing to a high standard of content in recent years.
On withdrawal of state funding, the S. Afr. J. Bot. became part of the NISC stable of journals, with electronic publication by Ingenta.
The current publication by Elsevier includes the benefits of electronic publication; no page charges; rapid online publication with Articles in Press; free use of colour; electronic archiving; 30% discount on Elsevier books; a large, worldwide readership; contents alerting services that are globally distributed; personalized citation alerts on Science Direct; worldwide marketing and exhibitions; author services and support with Author Gateway.
South African Journal of Plant and Soil (S. Afr. J. Plant Soil). The present title changed from Crop Production in 1983. It has incorporated both Applied Plant Science and Journal of the Southern African Society for Horticultural Sciences. It is published in collaboration with the South African Society of Crop Production, the Soil Science Society of South Africa, the Southern African Weed Science Society, the Southern African Plant Breeders' Association and the Southern African Society for Horticultural Sciences. Forum Press International is the publisher and there are four issues per year. The scientific editor is V. Tolmay of the Agricultural Research Council's Small Grain Institute in Bethlehem (J.B.J. van Rensburg was editor during this survey). The journal publishes refereed papers, short communications, book reviews, comments on papers recently published and, in exceptional cases, reviews on research in the fields of soil science and applied plant science.
The S. Afr. J. Plant Soil fills a unique niche in South Africa, delivering the published output from five scientific societies. The botanical papers that we have assessed from this journal indicate a trend towards the applied sub-disciplines. Most were in physiology, ranging from 4 to 19 per annum. Fewer ecology papers were published, numbers ranging from 1 to 7. The number of taxonomy papers, mostly descriptive, was small. Papers in the molecular sciences have been evident, and biotechnology papers have featured regularly since 1998.
Government institutions are the largest contributors of botanical papers to the journal, the source of 219 papers a year. Universities have contributed 312 articles. Papers by foreign authors have been erratic, at two or fewer annually. There have been only a few contributions from the private sector. The absence of contributions by SANBI is attributed to the applied nature of the journal content.
Strategies adopted by the journal have been:
Imposition of page charges.
It is published jointly by the five professional societies. Cooperation between these societies with respect to journal consolidation is a strategy that aims at a larger botanical community, while cutting costs.
These societies have provided an institutional website for electronic publication.
South African Journal of Science (S. Afr. J. Sci.). This bimonthly periodical is published by the Academy of Science of South Africa28,29 with G.S. Baker as editor. It was established by the South (now Southern) African Association for the Advancement of Science (S2A3) in 1903. After four decades of annual volumes, monthly issues were introduced in 1947.30 The S. Afr. J. Sci. is a multidisciplinary journal, broadly reflecting South Africa's scientific activity.28 Noting the multidisciplinary nature of the S. Afr. J. Sci., we have assessed the papers in ecology at 5 to17 per annum. Taxonomy papers have varied from 3 to 17 and physiology from 2 to16. Three biosystematics papers were published during 1988 to1993, and the trend in the number of biotechnology papers increased between 1998 and 2002.
The journal reflects a balance of various institutions that regularly contribute botanical papers. But for a slight decline in papers from 1997 to 1999, universities have constantly contributed between 11 and 29 botanical papers per annum. Government institutions have published 2 to 9 papers a year. Initial contributions from SANBI were relatively few, but 1 to 7 papers per annum have been published since 1992. Foreign authors contributed 1 to 22 papers from 1993 to 2002, and the private sector has also made a notable contribution.
The journal is now funded by the Department of Science and Technology through the Academy of Science of South Africa (ASSAf).28,29
Partial page charges generate additional funding.
This journal has enjoyed the advantages of electronic publication through SABINET Online and SA ePublications.31
Our survey indicates that each of the assessed journals has its own niche. Afr. J. Range For. Sci. favours applied ecology papers, whereas Bothalia publishes papers on taxonomy and ecology. S. Afr. J. Bot. is interdisciplinary, showing a gradual decline in the number of taxonomy and ecology papers and a notable increase in the number of physiology papers over the assessment period. The currently growing interest in ethnopharmacology, biosystematics and biotechnology has pressed this journal to publish more contributions in these fields. The S. Afr. J. Plant Soil tends towards the applied sub-disciplines, especially physiology.
Number of botanical articles published in the five South African journals from 1988 to 2002
Taxonomy made the largest contribution to the body of botanical publications, followed by ecology (see Fig. A online). These trends are because many universities, SANBI, and private and government organizations (especially those serving nature conservation and agriculture) focus on these sub-disciplines. Fewer physiology papers should be seen in context with the application of this sub-discipline, together with trends towards biotechnology, implying publication in specialized journals. Although molecular biology has attracted some of the best students, as well as improved funding,32 there were only a few research papers in this field appearing in South African journals during the assessment period. Articles in this sub-discipline from a South African address are likely to appear in foreign applied physiological and biotechnology journals.
Botanical publications peaked in number between 1988 and 1990 (Fig. B online). A decline followed in 1991 and in the mid-1990s. We reason that many botanists pursued contract and consultation work, either through lack of full-time employment or to supplement their income, and this activity does not generate open publications. A decline in the number of papers in 2000 could be the consequence of withdrawal of government funding from the BSP and the national scientific journals. The number of papers increased in 2001 and 2002 after the demise of the BSP, but did not reach the levels achieved in 198890. Current research shows a substantial increase in the number of publications in the plant and animal sciences during the period 19952005.7
Age and gender of contributors to the five South African journals between 1988 and 2002
Figure C indicates numerical trends with gender of authors, grouped according to age at publication. The survey period covers 15 years, and because productive authors contribute regularly over their careers, the best depiction is by reflecting author's age at publication date. Most articles are from the age group 3140, with a decline in output from the 4150, 5160 and 6175 age groups. At age 2030, women published more papers than men. Numbers of papers remain about constant up to the 5160 age group, from which we conclude that women in botany are not forsaking careers for family commitments. Men generally have an extended continuity in their careers, at a peak for age group 3140, with a decline in output thereafter. The number of papers by women in the 6175 age group only slightly exceeds that by men.
A 2002 survey showed that 83% of all South African research papers come from men, and 17% from women.33 Our analysis indicates that men generate about 68% of botanical papers (1223/1787), while women account for 32% (654/1787). We attribute the difference between the numbers of papers by men and women to traditional views on careers for women. Fewer female scientists probably arise from responsibilities such as parenthood. The situation has been partially addressed by government policies on employment equity and remuneration, as well as by provision of maternity and compassionate leave. The percentage of papers from female botanists during the report period was almost double that from women in other scientific disciplines. Blankley and Kahn34 have examined the demographic profile of South African researchers in 2004, and found that women comprised 35% of all researchers (compared with 49% in Argentina, 44% in Russia, 28% in Norway and 11% in Japan).
Our survey shows that 94% (2335/2482) of botanical papers, published from 19882002, come from white scientists, with other racial groups authoring 6% of the rest. The greatest proportion of scientific articles recorded by the South African Knowledgebase (SAK) and published in the years 199098 originated from white academics (94% approximate average), which is in close agreement with our result.33
We used ISI Journal Citation Reports (JCR)21 for comparison of selected South African botanical journals with other national and foreign journals.35,36 Of the five local journals assessed, Afr. J. Range For. Sci. and S. Afr. J. Plant Soil were not indexed in the JCR for 2002 or 2003, but had impact factors in 1996 of 0.279 and 0.063, respectively.8 At this time the S. Afr. J. Sci., S. Afr. J. Bot. and Bothalia were the only three South African journals publishing botany that were indexed in JCR.
The three journals mentioned above are compared with other periodicals in the biological disciplines, as the scope of South African journals that publish botany is limited (Table 3). Journals used in the analysis were African Entomology (Afr. Entomol.), African Zoology (Afr. Zool.), South African Journal of Animal Science (S. Afr. J. Anim. Sci.), South African Journal of Marine Science [S. Afr. J. Mar. Sci.; which changed its title in 2003 to African Journal of Marine Science (Afr. J. Mar. Sci.)] and South African Journal of Wildlife Research (S. Afr. J. Wildl. Res.).
Summary of results:
S. Afr. J. Sci. scored 1397 citations, followed by the S. Afr. J. Mar. Sci. with 915 (Afr. J. Mar. Sci. 58). The number of citations for the two botanical journals S. Afr. J. Bot. (445) and Bothalia (286) were higher than the other South African journals, with values ranging from 39 to 232.
The number of articles published in 2003 are S. Afr. J. Sci., 89; S. Afr. J. Bot. and Afr J Mar Sci., 49. All the other journals published 1539 articles per annum.
Of the eight selected South African journals, six had impact factors above 0.3; that of the S. Afr. J. Sci. was 0.93 and that of Afr. J. Mar. Sci., reached 0.89.
Afr. J. Mar. Sci. had the highest immediacy index (1.184) (citations to current articles/number of current articles). The immediacy indices of the two botanical journals S. Afr. J. Bot. (0.469) and Bothalia (0.067) as well as that of S. Afr. J. Sci. (0.124) exceeded those of most other selected journals in the biological disciplines, these ranging from 0 to 0.059.
Cited half-life values of 10 or more are given for Bothalia, S. Afr. J. Bot., Afr. J. Mar. Sci. and S. Afr. J. Wildl. Res., implying that there is a stretch of 10 or more years over which 50% of the journal's articles have accumulated citations, covering years 1993 to 2003.
Table 3 reflects relatively low immediacy indices for journals publishing in classical taxonomy. The published information in taxonomy is of global importance, and the description of specific taxa has long-term significance but does not tend to attract immediate citation. When reference to a scientific name of a plant is made, it is customary to cite, within the text, the author(s) that are responsible for the nomenclature. Since such citation does not appear in appended references at the end of papers, it is not reflected in citation analyses.
The cited half-life is the age-range of half of the cited articles of a journal. If the half-life is relatively long, it implies an extended relevance of the published material, which is the case in plant taxonomy.
Comparison of selected South African journals, publishing botany, with foreign journals (Table 3)
The South African journals were benchmarked by comparing them with foreign peer journals that commonly publish articles in all sub-disciplines of botany (Fig. D online). The latter used in the analysis were American Journal of Botany (Am. J. Bot.), Australian Journal of Botany (Aust. J. Bot.), Botanical Journal of the Linnean Society (Bot. J. Linn. Soc.), Botanical Review (Bot. Rev.) and Canadian Journal of Botany (Can. J. Bot.).
The Am. J. Bot. records the largest total citations, together with number of articles, and the highest impact factor (2.37). Bot. Rev. scored the second-highest impact factor of 1.82 (number of citations at 1329/number of articles at 12). By contrast, in 2003, both Bothalia (286 citations/15 articles) and S. Afr. J. Bot. (445 citations/49 articles) had impact factors below 0.5. The impact factor is raised by an elevated numerator (the number of citations to recent articles), or by a depressed denominator (the number of recent articles included). In practice, both Bothalia and S. Afr. J. Bot. have played a major role in serving the botanical community of South Africa, and have published more articles per individual issue than Bot. Rev. Impact factors of both were lower as a consequence of the calculation method, and so give an unflattering impression in journal assessments made by science councils and potential contributors. In our experience, botanists tend to be advised, in the course of in-house performance assessments, to publish abroad, to the detriment of our local journals.
Impact factors tend to fluctuate (Fig. D): for the Am. J. Bot., it ranged from 2.066 to 2.463. The impact factors of both Aust. J. Bot. and Can. J. Bot. exceeded 1.0 in 1999, but declined to 0.9 in 2003. The impact factors of the two South African journals were the lowest during this period. Bothalia ranged between 0.176 and 0.358 and S. Afr. J. Bot. between 0.136 and 0.522. The impact factor of the S. Afr. J. Sci. rose from 0.328 in 1998 to 0.930 in 2003.
The relatively low citation indices of our botanical journals is doubtless predictable, as the primary focus is South African botany. Furthermore, financial constraints have limited foreign marketing and distribution of local publications. Limited readership translates into limited citation. Lastly, our journals are perceived from abroad as being (less-significant) southern hemisphere publications, even though they report on priority issues in biodiversity, sustainability and conservation in one of the world's richest floral regions.
Both Bothalia and S. Afr. J. Sci. have permanent editors and support staff, remunerated by SANBI and ASSAf, respectively. Afr. J. Range For. Sci., S. Afr. J. Bot. (until taken over by Elsevier) and S. Afr. J. Plant Soil, in contrast, are funded by their respective scientific societies, without formal remuneration of editors or support staff.
The recent history of South Africa, with a change to a democratic government in 1994, and the consequential adoption of new policies and funding practices, are identified as contributors to the decline in botanical science during the survey period; for example, by the decrease in number of taxonomists/systematists, amalgamation of journals and professional societies, and inadequate funding as mentioned above.3,9 The restructuring of higher education, and the scientific institutions, linked with the accompanying infrastructural, financial, social and work-related changes, has had a profound influence on the productivity of botanists. A large onus was placed on botanists in the mid-90s to adapt to change, but some of our best opted for emigration, leaving South Africa with a deficit of competent and qualified people in the field, a trend that may apply beyond botanical science. Others have made career changes. The decline in the number of botanical articles published during the mid-1990s (Fig. B) is identified as a direct consequence. The numbers of articles have since increased, due to adoption of new policies and an accommodation to the new dispensation.
Molecular biology and its sub-disciplines are areas of high growth and commercially exploitable potential. The current global trend towards molecular bio-research has had a profound impact on all biological disciplines, including botany. 'Rationalization' of biological disciplines has taken place at most South African universities and several are now structured together under the banner of 'Biological Sciences' or 'Schools of Environmental Sciences and Development', as examples. Funding has been channelled to molecular biology and biotechnology, resulting in students following these sub-disciplines. Although molecular biology and biotechnology have existed for years, they are poorly represented in South African journals during our period of review.
Immense challenges remain for the botanical sciences in South Africa at both the 'macro' and the 'micro' levels. A decline in the number of botany students is unaffordable, and recruitment is an absolute necessity. Career opportunites is a prime consideration when choosing a vocation and government remains the main employer of botanists. Students have believed that degrees in the molecular biosciences will guarantee permanent employment, but the reality in South Africa remains that these posts in scientific institutions and private enterprise are limited. However, with cabinet approval of the National Biotechnology Strategy for South Africa in 2001 and increased investment in modern biotechnology, expanded career opportunities are at hand.32
These structures have coerced many botanists to become self-employed after graduation. Government's latest conservation and environmental policies offer opportunities for entrepreneurship in botany, especially in ecology, undertaking environmental impact assessments, creating outputs that do not contribute to statistics covering open scientific publications. According to Herbert,38 in 2001, the NRF regarded conservation and management of ecosystems and biodiversity as areas of lesser need in the allocation of funding. The future of taxonomy can suffer further threat, with consequent impact upon future advancements in the study and the protection of biodiversity in South Africa. The growth of relevant South African journals will also be at risk. Currently, the NRF37 is hosting the South African Biosystematics Initiative (SABI)39 (embedded within the Conservation and Management of Ecosystems and Biodiversity Focus Area) aimed at enhancing the country's capacity to undertake research in biosystematics.
Our assessment of trends in South African research publications40 shows that only three disciplines have produced more than 1000 publications during the period 20002004. According to the ISI field categories, these are plant sciences (2182 publications), animal sciences (2108 papers) and environment/ecology (1187 articles). Moreover, an analysis of papers generated in the 19952005 period indicated that the combined field of plant and animal sciences was the most productive in South Africa.7 As Jeenah and Pouris point out, research publications are a proxy for scientific activity.
Some assessed journals have failed to comply with ISI accreditation and evaluation procedures during our assessment period and some of them remain unaccredited. Current evaluation procedures should dictate ISI accreditation for all scientific journals.
Professional societies representing the botanical community, editors of the five journals and their publishers have collectively found new strategies for their sustained existence and innovations have been implemented.
The extent and quality of botanical articles must be continually monitored and maintained by all the assessed journals in the interest of funding for future academic publication.
Electronic publication is now a well-established alternative or complement to print production. Access to these journals on the internet and downloading of articles should be pursued and promoted to increase efficiency of publication, as well as international visibility.
Mentoring programmes are being introduced at scientific institutions, to advise young botanists on how to publish research results.
Rated botanists need to publish their best work in South African as well as good foreign journals; these publications are increasingly available to emerging botanical scientists on the web.
Ratification of the CBD, the Biodiversity white paper41 and the white paper on Science and Technology42 obliges government to address the needs of biological research. The adoption of the Biodiversity Bill on 31 May 2004 is evidence of government's commitment to the achievement of this goal.
