Divergence in the ecological niches of the white wagtail (Motacilla alba Linnaeus, 1758) complex using the ecological niche modeling approach [PDF]

open access: yesIranian Journal of Animal Biosystematics, 2017
The mtDNA data presently being used for estimating biodiversity is not sufficient for evaluating the Motacilla alba complex species status. Because there is a lack of congruence between morphological and mtDNA data, there are debates about the best ...

Range expansion of Ambrosia artemisiifolia in Europe is promoted by climate change [PDF]

open access: yes, 2013
Ambrosia artemisiifolia L., native to North America, is a problematic invasive species, because of its highly allergenic pollen. The species is expected to expand its range due to climate change.

Evaluation of climate conditions and ecological traits that limit the distribution expansion of alien Lolium rigidum in Japan [PDF]

open access: yesNeoBiota
Invasive alien plants cause severe global problems; therefore, determining the factors that lead to the success or failure of invasion is a critical question in the field of invasion ecology.

PREDICTING INVASION RISK USING MEASURES OF INTRODUCTION EFFORT AND ENVIRONMENTAL NICHE MODELS

open access: yesEcological Applications, 2007
The Chinese mitten crab (Eriocheir sinensis) is native to east Asia, is established throughout Europe, and is introduced but geographically restricted in North America. We developed and compared two separate environmental niche models using genetic algorithm for rule set prediction (GARP) and mitten crab occurrences in Asia and Europe to predict the ...

a variational approach to niche construction [PDF]

open access: yes, 2018
In evolutionary biology, niche construction is sometimes described as a genuine evolutionary process whereby organisms, through their activities and regulatory mechanisms, modify their environment such as to steer their own evolutionary trajectory, and ...

Using environmental niche models to test the ‘everything is everywhere’ hypothesis for Badhamia [PDF]

open access: yesThe ISME Journal, 2013
Abstract It is often discussed whether the biogeography of free-living protists is better explained by the ‘everything is everywhere’(EiE) hypothesis, which postulates that only ecology drives their distribution, or by the alternative hypothesis of ‘moderate endemicity’ in which geographic barriers can limit their dispersal.

Modelling Niche Differentiation of Co-Existing, Elusive and Morphologically Similar Species: A Case Study of Four Macaque Species in Nakai-Nam Theun National Protected Area, Laos

open access: yesAnimals, 2013
Species misidentification often occurs when dealing with co-existing and morphologically similar species such as macaques, making the study of their ecology challenging.

Direct and indirect effects of environmental factors on dietary niches in size-structured populations of a wild salmonid [PDF]

open access: yes, 2015
Dietary plasticity of populations can be associated to ontogenetic diet preferences and depends on the size-structure of populations. Dietary niche characterizes the functional role of organisms in a food web, as it reflects both resources' diversity ...

Effects of species traits and environmental predictors on performance and transferability of ecological niche models [PDF]

open access: yesScientific Reports, 2019
AbstractThe ability of ecological niche models (ENMs) to produce robust predictions for different time frames (i.e. temporal transferability) may be hindered by a lack of ecologically relevant predictors. Model performance may also be affected by species traits, which may reflect different responses to processes controlling species distribution.
