ABSTRACTA wide range of modelling algorithms is used by ecologists, conservation practitioners, and others to predict species ranges from point locality data. Unfortunately, the amount of data available is limited for many taxa and regions, making it essential to quantify the sensitivity of these algorithms to sample size. This is the first study to address this ne...... hiện toàn bộ Conservation Biogeography: assessment and prospect Tập 11 Số 1 - Trang 3-23 - 2005

ABSTRACTThere is general agreement among scientists that biodiversity is under assault on a global basis and that species are being lost at a greatly enhanced rate. This article examines the role played by biogeographical science in the emergence of conservation guidance and makes the case for the recognition of Conservation Biogeography as a key subfield of conser...... hiện toàn bộ Evaluation of consensus methods in predictive species distribution modelling Tập 15 Số 1 - Trang 59-69 - 2009

ABSTRACTAim Spatial modelling techniques are increasingly used in species distribution modelling. However, the implemented techniques differ in their modelling performance, and some consensus methods are needed to reduce the uncertainty of predictions. In this study, we tested the predictive accuracies of five consensus methods, namely Weigh...... hiện toàn bộ The importance of correcting for sampling bias in MaxEnt species distribution models Tập 19 Số 11 - Trang 1366-1379 - 2013

AbstractAimAdvancement in ecological methods predicting species distributions is a crucial precondition for deriving sound management actions. Maximum entropy (MaxEnt) models are a popular tool to predict species distributions, as they are considered able to cope well with sparse, irregularly sampled data and minor location errors...... hiện toàn bộ Global amphibian declines: sorting the hypotheses Tập 9 Số 2 - Trang 89-98 - 2003

Abstract. Reports of malformed amphibians and global amphibian declines have led to public concern, particularly because amphibians are thought to be indicator species of overall environmental health. The topic also draws scientific attention because there is no obvious, simple answer to the question of what is causing amphibian declines? Complex interactions of seve...... hiện toàn bộ Infectious disease and amphibian population declines Tập 9 Số 2 - Trang 141-150 - 2003

Abstract.A series of recent papers have implicated pathogens and parasites in amphibian population declines. Here, we review evidence on the link between infectious disease and amphibian population declines. We conclude that available data provide the clearest link for the fungal disease amphibian chytridiomycosis, although other pathogens are also implicated. We sug...... hiện toàn bộ
