The urgency of building global capacity for biodiversity science

The biodiversity sciences represent the disciplines of whole-organism biology, including systematics, ecology, population biology, behaviour and the fields of comparative biology. The biodiversity sciences are critically important to society because it is knowledge of whole-organisms that is essential for managing and conserving the world's species. Because of an acceleration in environmental degradation and global biodiversity loss in recent decades, the need for the biodiversity sciences has never been more urgent. Yet, biodiversity science is not well supported relative to other fields of science, and thus the need for knowledge about organisms and their environment is far outstripping biologists' ability to provide it. National and international capacity for biodiversity science must therefore be increased substantially. Each nation should establish a national biodiversity research programme coordinated across all government agencies. An international biodiversity research programme should also be established, perhaps with an organizational structure that parallels the International Geosphere-Biosphere Programme. Biodiversity scientists must assume a leadership role in educating the public and bringing about policy changes that will enhance our understanding of the world's species and their ecosystems.     

Systematics,conservation and sustainable development

The contribution of systematics to conservation and sustainable use of species is discussed. An adequate inventory of species is required for both areas and recent field work shows that the inventory is far from complete. This supports the first mission of Agenda 2000 which is to discover described and inventory global species diversity. The importance of making these data available in data base format is stressed. Sound systematics is a necessity for conservation legislation where control depends on the ability to identify organisms correctly. The establishment of reserves is also dependent upon data from systematics about centres of diversity and endemism and examples of this are given. Molecular systematics has made new tools available to conservation such as genetic fingerprinting which is useful both to breeding programmes of rare species and for identification for legal proceedings.Systematics is also one of the foundations for programmes of sustainable development especially in the search for new crops, non-timber forest plants from extraction forests and the identification of wild relatives of crop species. Examples of the role of systematics in a fuelwood programme in Zimbabwe, a sustainable development programme in northeast Brazil and in the search for a chemical component with medicinal properties for curing AIDS are given. The more predictive a classification we can develop using modern cladistic and molecular techniques the more useful systematics will be for both conservation and sustainable development. The goal of Agenda 2000 to organize the information derived from the programme in an efficiently retrievable form that best meets the needs of science and society is a laudable target that is crucial for conservation and the sustainable use of the plant resources of the world.

Systematics Agenda 2000: an historical perspective

The publication of Systematics Agenda 2000 in February, 1994 represented an historic event in the collaboration of the systematic biology community designed to set a research agenda for a twenty five year period across the areas of basic and applied systematics. How the community came to take the initiative to produce such a consensus is outlined. Of special interest is the emergence of the Systematics Agenda 2000 initiative from a North American perspective to a truly global enterprise.     

Fungi and international biodiversity initiatives

The origin of the term biodiversity, its various meanings, and current usage are explored. Renewed interest in the subject has spawned a variety of international initiatives at both the political and scientific levels, many of which are relevant to mycologists. The political initiatives include the Convention on Biological Diversity and Biodiversity Action Plans, and the scientific a broad spectrum: the Global Biodiversity Assessment, Species 2000, Systematics Agenda 2000 International, BioNET INTERNATIONAL, DIVERSITAS, All Taxa Biodiversity Inventory, and Biodiversity Methods Manuals. Mycologists need to be aware of, and contribute to, such programmes, maintain an enhanced profile, and remain flexible to respond to new challenges.     

International Biodiversity Observation Year in Western-Pacific and Asian regions (DIWPA-IBOY): a case report on species rarity and spatio-temporal variability of species composition in Lepidoptera and Coleoptera communities from a temperate forest of northern Japan

An international project, DIWPA-IBOY, took place for simultaneously observing biodiversity throughout the Western-Pacific and Asian regions in 2001–2003, as one of the core projects for International Biodiversity Observation Year, a crosscutting network activity of DIVERSITAS (an international programme of biodiversity science). DIWPA-IBOY provides extensive data on species diversity obtained by the standardized method. Under this project, 51,742 individuals of Lepidoptera and 11,633 of Coleoptera were collected by light traps from the Tomakomai Experimental Forest of Hokkaido University, one of the core DIWPA-IBOY sites, in the cool-temperate region of northern Japan. Based on these data, this study examined the relative abundance distribution (RAD) to evaluate the amount of rare species in the Lepidoptera and Coleoptera communities. The beta diversities between sampling seasons, forest strata, and trap sites were also assessed to evaluate the spatio-temporal variability of species composition in these communities. In the analysis of the RAD, the best-fit model was selected from the log-Normal, Zipf–Mandelbrot, and Zipf models differing in the tail length of the RAD, i.e., the proportion of rare species. To explore the beta diversity between samples, the abundance-based Jaccard index with an unseen species estimator was calculated, and then a hierarchical clustering analysis was conducted. As a result of RAD analysis, the Coleoptera community was regarded as containing a larger proportion of rare species than the Lepidoptera community. The seasonal compartmentalization of the community, deduced from the beta-diversity analysis, was finer in Lepidoptera (seven assemblages recognized) than in Coleoptera (three assemblages). The spatial (vertical and horizontal) compartmentalization was negligible in both communities. The coincidence of the larger proportion of rare species and the lower beta diversity between seasons in the Coleoptera community was explained by the longer life spans of beetles compared to moths, based on the assumption that the length of life span acts as a temporal agent for mass effect on the analogy of the migration rate as a spatial agent for mass effect.     

Climate impacts and oceanic top predators: moving from impacts to adaptation in oceanic systems

Climate impacts are now widely reported from coastal marine systems, but less is known for the open ocean. Here we review progress in understanding impacts on large pelagic species presented at an international workshop for the Climate Impacts on Oceanic Top Predators programme, and discuss the future with regard to the next phase of adaptation-focused research. Recent highlights include a plan to map the distribution of key species in the foodweb using both acoustics and biochemical techniques, and development of a new data sharing and access tool for fisheries and associated data, including socio-economic information. A common research focus in pelagic ecosystems is on understanding climate variability and climate change impacts on marine species, but a greater emphasis on developing future scenarios and adaptation options is needed. Workshop participants also concluded that engagement with and provision of science support to regional fisheries management organisations are critical elements for ensuring successful uptake of research. This uptake will be required for future management of fisheries as global warming continues such that some open ocean top predators can be sustainably harvested, impacts on conservation-dependent species can be avoided, and ecosystem function is not compromised.     

High-school students in university research labs? Implementing an outreach model based on the ‘science as inquiry’ approach

In this study we designed, implemented, and evaluated an outreach programme for high-school biology students rooted in the ‘science as inquiry’ approach. Accordingly, students learn about science from experts in the field, as well as through in-class exposure to the history and philosophy of science. Our sample consisted of 11th graders (n?=?497), ages 16–17, attending advanced biology classes. Our goal was to determine whether this programme had a significant effect on students’ understanding of the ‘nature of science’ (NOS) and on their attitudes towards science. Using a controlled pre-post research design, we asked participants to complete a Likert-like questionnaire. Also, we conducted post-programme semi-structured interviews with 35 of the participants. Results show that completion of the programme significantly enhanced participants’ NOS understanding and improved their attitudes towards science. Participants expressed a deep level of NOS understanding and explicitly stated that the field visits to experts’ labs had changed their attitude towards science. We believe that our outreach programme can be adapted for teaching other sciences and for societies worldwide, as long as there is access to university laboratories and researchers willing to interact with young citizens and potential future scientists.     

Citizen science in schools: Engaging students in research on urban habitat for pollinators

Citizen science can play an important role in school science education. Citizen science is particularly relevant to addressing current societal environmental sustainability challenges, as it engages the students directly with environmental science and gives students an understanding of the scientific process. In addition, it allows students to observe local representations of global challenges. Here, we report a citizen science programme designed to engage school‐age children in real‐world scientific research. The programme used standardized methods deployed across multiple schools through scientist–school partnerships to engage students with an important conservation problem: habitat for pollinator insects in urban environments. Citizen science programmes such as the programme presented here can be used to enhance scientific literacy and skills. Provided key challenges to maintain data quality are met, this approach is a powerful way to contribute valuable citizen science data for understudied, but ecologically important study systems, particularly in urban environments across broad geographical areas.
