Being able to efficiently and accurately delimit species is one of the most basic and important aspects of systematics because species are the fundamental unit of analysis in biogeography, ecology, and conservation. We present a rationale and approach for combining ecological niche modeling, spatially explicit analyses of environmental data, and phylogenetics in species delimitation, and we use...

Rainforest frogs are classi¢ed into nine ecological guilds based on features of reproduction, habitat use, temporal activity, microhabitat and body size. The largest ecological di¡erences are between the microhylid frogs and the rest of the frog species. Within the non-microhylids, there are two primary groups consisting of (i) regionally endemic rainforest specialists, and (ii) a more ecologic...

The genus Ranunculus L., with a worldwide distribution, is the largest member of the Ranunculaceae. Here, nuclear ribosomal internal transcribed spacer (ITS) sequence data and chloroplast trnLF sequence data were used to analyze phylogenetic relationships among members of the annual and perennial (Group Praemorsa, Group Rhizomatosa, Group Grumosa and Group non-Grumosa) species of Ranunculus...

We present a method for modeling multiple species distributions simultaneously using Dirich1 let Process random effects to cluster species into guilds. Guilds are ecological groups of 2 species that behave or react similarly to some environmental conditions. By modeling latent 3 guild structure, we capture the cross-correlations in abundance or occurrence of species over 4 surveys. In addition,...

Recent advances in animal personality research have established the ecological importance of the multidimensional behavioural volume occupied by individuals and by multispecies communi...

The aim of this study was modelling the spatial distribution ofLilium ledebourii (Baker) Boiss. based on ecological characteristics, in order to predict potential habitats for conservation of a rare plant. Knowledge of the spatial distributions of rare and threatened species and the underlying ecological factors plays an important role in regional conservation assessments and development planni...

numerous ecological risk assessment methodologies have been developed over the last twenty years around the world for evaluating effects of pollutant on receptors such as different wildlife species. but so far such methods have only rarely been used to determine potential ecological risks in iran. therefore in this study we used one of these methodologies (eco-ssls) to determine ecological risk...

the current study aims to ordinate ecological groups in the wetlands of northern and eastern slopes of the sabalan mountain and investigate their relationship with environmental variables. the location of wetlands was found using field surveys and satellite images. in total, 32 wetland sites were identified for the sampling purpose. 320 sample plots (relevé) were selected using the systematic-r...
