Little ecological divergence associated with speciation in two African rain forest tree genera [PDF]

open access: yes, 2011
Background: The tropical rain forests (TRF) of Africa are the second largest block of this biome after the Amazon and exhibit high levels of plant endemism and diversity.

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

Ecological niche divergence or ecological niche partitioning in a widespread Neotropical bird lineage [PDF]

open access: yesPeerJ
Ecological niche divergence is generally considered to be a facet of evolution that may accompany geographic isolation and diversification in allopatry, contributing to species’ evolutionary distinctiveness through time.

Uses and Requirements of Ecological Niche Models and Related Distributional Models [PDF]

open access: yes, 2006
.—Modeling approaches that relate known occurrences of species to landscape features to discover ecological properties and predict geographic occurrences have seen extensive recent application in ecology, systematics, and conservation. A key component in

Importance of biotic predictors in estimation of potential invasive areas: the example of the tortoise beetle Eurypedus nigrosignatus, in Hispaniola [PDF]

open access: yesPeerJ, 2018
Climatic variables have been the main predictors employed in ecological niche modeling and species distribution modeling, although biotic interactions are known to affect species’ spatial distributions via mechanisms such as predation, competition, and ...

Ecological niche modeling of bioindicator mosses

open access: yes, 2021
As briófitas podem ser utilizadas como bioindicadoras, no entanto, uma das limitações desse uso são as lacunas no conhecimento sobre a ocorrência das espécies. Assim, o presente estudo teve como objetivo realizar a modelagem de nicho ecológico para Helicodontium capillare (Hedw.) A.Jaeger e Thuidium tomentosum Schimp., duas espécies de musgos ...

Evolution of the climatic tolerance and postglacial range changes of the most primitive orchids (Apostasioideae) within Sundaland, Wallacea and Sahul [PDF]

open access: yesPeerJ, 2016
The location of possible glacial refugia of six Apostasioideae representatives is estimated based on ecological niche modeling analysis. The distribution of their suitable niches during the last glacial maximum (LGM) is compared with their current ...

Niche divergence and limits to expansion in the high polyploid Dianthus broteri complex [PDF]

open access: yes, 2019
Niche evolution in plant polyploids remains controversial and evidence for alternative patterns has been reported. Using the autopolyploid Dianthus broteri complex (2×, 4×, 6× and 12×) as a model, we aimed to integrate three scenarios – competitive ...
