The cumulative niche approach: A framework to assess the performance of ecological niche model projections

open access: yesEcology and Evolution, 2023
AbstractEcological Niche Models (ENMs) are often used to project species distributions within alien ranges and in future climatic scenarios. However, ENMs depend on species‐environment equilibrium, which may be absent for actively expanding species. We present a novel framework to estimate whether species have reached environmental equilibrium in their

Collinearity in ecological niche modeling: Confusions and challenges [PDF]

open access: yesEcology and Evolution, 2019
AbstractEcological niche models are widely used in ecology and biogeography. Maxent is one of the most frequently used niche modeling tools, and many studies have aimed to optimize its performance. However, scholars have conflicting views on the treatment of predictor collinearity in Maxent modeling.

Sympatric and allopatric niche shift of endemic Gypsophila (Caryophyllaceae) taxa in the Iberian Peninsula. [PDF]

open access: yesPLoS ONE, 2018
Several species of the Gypsophila genus are endemic to the Iberian Peninsula, including gypsophytes of particular ecological, evolutionary and biochemical interest, and taxa that have undergone both sympatric and allopatric genetic differentiation.

Incorporating intraspecific variation into species distribution models improves climate change analyses of a widespread West African tree species (Pterocarpus erinaceus Poir, Fabaceae)

open access: yesGlobal Ecology and Conservation, 2023
Climate change is predicted to affect species distribution worldwide. Most of the methods used to evaluate such impact so far assume that species respond to the environmental gradients in a uniform way along their distribution range.

Ecological Niche Modeling: An Introduction for Veterinarians and Epidemiologists [PDF]

open access: yesFrontiers in Veterinary Science, 2020
Most infectious diseases in animals are not distributed randomly. Instead, diseases in livestock and wildlife are predictable in terms of the geography, time, and species affected. Ecological niche modeling approaches have been crucial to the advancement of our understanding of diversity and diseases distributions.

Interspecific hybridization explains rapid gorget colour divergence in Heliodoxa hummingbirds (Aves: Trochilidae)

open access: yesRoyal Society Open Science, 2023
Hybridization is a known source of morphological, functional and communicative signal novelty in many organisms. Although diverse mechanisms of established novel ornamentation have been identified in natural populations, we lack an understanding of ...

Long-term isolation of European steppe outposts boosts the biome’s conservation value

open access: yesNature Communications, 2020
Europe hosts isolated remnants of the steppe belt that once covered much of Eurasia. Here the authors combine genomic data and ecological niche modelling on three plant and three insect species to show evolution independent of the zonal steppe and high ...

Labeling Ecological Niche Models

open access: yesNatureza & Conservação, 2012
The ongoing biodiversity crisis is pushing ecologists and conservation biologists to develop models to foretell the effects of human-induced transformation of natural resources on the distribution of species, although ecology and biogeography still lacks a paradigmatic body of theory to fully understand the drivers of biodiversity patterns. Two decades

Multiple markers, niche modelling, and bioregions analyses to evaluate the genetic diversity of a plant species complex

open access: yesBMC Evolutionary Biology, 2017
Background The classification of closely related plants is not straightforward. These morphologically similar taxa frequently maintain their inter-hybridization potential and share ancestral polymorphisms as a consequence of their recent divergence ...
