The study assessed the effects of agricultural practices on biodiversity in Olamaboro Local Government Are of Kogi State, Nigeria. One hundred and fifty (150) farmers (respondents) were sampled using simple random sampling technique from five council wards (30 farmers per council ward). Data collected were analyzed using descriptive statistics and Logit regression model. Results showed that 63%...

during an investigation on cladosporium species associated with numerous substrates of various localities in iran during 2011-13, eight species including c. delicatulum, c. echinulatum, c. exile, c. macrocarpum, c. neriicola, c. pannosum, c. scabrellum and c. uredinicola were identified based on the morphological characters. all these species are new records for the iranian mycobiota, except fo...

The emergence of “big data” offers unprecedented opportunities for not only accelerating scientific advances, but also enabling new modes of discovery. While we understand how to automate routine aspects of data management and analytics, most elements of the scientific process currently require considerable human expertise and effort. We argue that realizing the full potential of data to accele...

Historical collections of biological specimens are potentially rich sources of data for contemporary researchers. However, many technical issues have to be addressed in order to make these collections widely available. This paper reports on a qualitative study of historical and current data practices at the Academy of Natural Sciences, Philadelphia, which is seeking wider understanding of the h...

Many biodiversity researchers have responded to the financial constraints faced by policy makers to develop models based upon the “Noah’s Ark” metaphor, implying that society can save only a limited amount of biodiversity. Unfortunately, as Herman Daly (Land Economics, 1991) pointed out, such microeconomic rules can allow an ark to sink albeit in some optimal fashion. So, I step back to look at...

Glossary Convention on biological diversity The Convention was first enacted in June 1992, has been signed by many countries, and its objectives are the conservation of biological diversity, the sustainable use of its components and the fair and equitable sharing of the benefits arising out of the utilization of genetic resources, including by appropriate access to genetic resources and by appr...

Anthropogenic activities have accelerated the rate of global loss of biodiversity, making it more important than ever to understand the structure of biodiversity hotspots. One current focus is the relationship between species richness and aboveground biomass (AGB) in a variety of ecosystems. Nonetheless, species diversity, evenness, rarity, or dominance represent other critical attributes of bi...

Overview. The aim of the paper is to evaluates how adequately biodiversity has been assessed in reports on Environmental Impact Assessments. The analysis is based the reports available from a number of EIAs, including scoping reports, specialist studies and Environmental Impact Reports. References to biodiversity, and biodiversity related issues, were classified according to whether they addres...

Biodiversity is often ill-defined and subjectively surveyed, resulting in inefficient and ambiguous estimates. Strengths and deficiencies of prevailing survey techniques are appraised through a review of selected literature. Analogies with forest inventory are used to suggest options for more efficient and rigorous biodiversity assessment. Techniques such as variable-probability and model-based...
