Species Distribution Models Do Not Account for Abundance: The Case of Arthropods on Terceira Island

摘要: The objective of this study is to investigate whether presence/absence models can be used as surrogates arthropod abundance, and eventually under which circumstances such surrogacy guaranteed. Presence/absence data for 48 species from Terceira Island were modelled using artificial neural networks. Probabilities occurrence correlated with abundance a standardized survey programme. Although tendency was found vagile show relationships, only nine showed significant positive correlations between probability presence abundance. Five these exotic spider high abundances wide distributions in several human-modified habitats. patchy distribution pristine habitats, the capacity reach them probable low dependence on limiting resources, other than food, enhance relationship. A lack majority may due historical events, inappropriate scale, de...
