Global Habitat Suitability and Ecological Niche Separation in the Phylum Placozoa. [PDF]

open access: yesPLoS ONE, 2015
The enigmatic placozoans, which hold a key position in the metazoan Tree of Life, have attracted substantial attention in many areas of biological and biomedical research.

Spatial prediction of species’ distributions from occurrence-only records: combining point pattern analysis, ENFA and regression-kriging [PDF]

open access: yes, 2009
A computational framework to map species’ distributions (realized density) using occurrence-only data and environmental predictors is presented and illustrated using a textbook example and two case studies: distribution of root vole (Microtes oeconomus ...

Fit-for-purpose: species distribution model performance depends on evaluation criteria - Dutch Hoverflies as a case study. [PDF]

open access: yesPLoS ONE, 2013
Understanding species distributions and the factors limiting them is an important topic in ecology and conservation, including in nature reserve selection and predicting climate change impacts.

A kingdom in decline: Holocene range contraction of the lion (Panthera leo) modelled with global environmental stratification [PDF]

open access: yesPeerJ, 2021
Aim We use ecological niche models and environmental stratification of palaeoclimate to reconstruct the changing range of the lion (Panthera leo) during the late Pleistocene and Holocene. Location The modern (early 21st century) range of the lion extends

Modelling fire occurrence at regional scale. Does vegetation phenology matter? [PDF]

open access: yes, 2015
Through its influence on biomass production, climate controls fuel availability affecting at the same time fuel moisture and flammability, which are the main determinants for fire ignition and propagation.

Environmental heterogeneity affects the location of modelled communities along the niche–neutrality continuum [PDF]

open access: yesProceedings of the Royal Society B: Biological Sciences, 2014
The continuum hypothesis has been proposed as a means to reconcile the contradiction between the niche and neutral theories. While past research has shown that species richness affects the location of communities along the niche–neutrality continuum, there may be extrinsic forces at play as well. We used a spatially explicit continuum model to quantify

Ecological niche divergence associated with species and populations differentiation in Erythrophleum (Fabaceae, Caesalpinioideae) [PDF]

open access: yesPlant Ecology and Evolution, 2019
Background and aims – The isolation of populations inside forest refugia during past climate changes has widely been hypothesized as a major driver of tropical plant diversity.

INTEGRATING PHYLOGENETICS AND ENVIRONMENTAL NICHE MODELS TO EXPLORE SPECIATION MECHANISMS IN DENDROBATID FROGS [PDF]

open access: yesEvolution, 2004
We developed an approach that combines distribution data, environmental geographic information system layers, environmental niche models, and phylogenetic information to investigate speciation processes. We used Ecuadorian frogs of the family Dendrobatidae to illustrate our methodology.

Correlations between spatial sampling biases and environmental niches affect species distribution models

open access: yesGlobal Ecology and Biogeography, 2022
AbstractAimSpatial sampling biases in biodiversity data arise because of complex interactions between geography, species characteristics and human behaviour, including preferences for or against particular species or habitats; biases are therefore not necessarily independent of the environmental niches of species.

The inference of gray whale (Eschrichtius robustus) historical population attributes from whole-genome sequences

open access: yesBMC Evolutionary Biology, 2018
Background Commercial whaling caused extensive demographic declines in many great whale species, including gray whales that were extirpated from the Atlantic Ocean and dramatically reduced in the Pacific Ocean.
