Viral quasispecies profiles as the result of the interplay of competition and cooperation [PDF]

, 2010
Viral quasispecies can be regarded as a swarm of genetically related mutants or a quasispecies (QS). A common formalism to approach QS is the replicator-mutator equation (RME).

Stochastic Processes Shape Bacterial Community Diversity Patterns along Plant Niche Gradients

Agronomy
The ecological niche gradient is an important determinant of microbial community structure. In this paper, we studied variation in rhizosphere bacterial diversity and community composition along an ecological niche gradient.

A method for statistically comparing spatial distribution maps

International Journal of Health Geographics, 2009
Background Ecological niche modeling is a method for estimation of species distributions based on certain ecological parameters. Thus far, empirical determination of significant differences between independently generated distribution maps for a single ...

To what degree are philosophy and the ecological niche concept necessary in the ecological theory and conservation? [PDF]

, 2017
Ecology as a field produces philosophical anxiety, largely because it differs in scientific structure from classical  physics. The hypothetical deductive models of classical physics are simple and predictive; general ecological models are ...

Ecological niche modeling of the genus Papio

American Journal of Physical Anthropology, 2018
AbstractObjectiveEcological niche modeling (ENM) has been used to assess how abiotic variables influence species distributions and diversity. Baboons are broadly distributed throughout Africa, yet the degree of climatic specialization is largely unexplored for individual taxa. Also, the influence of climate on baboon phylogenetic divergence is unknown.

Comparative analysis of remotely-sensed data products via ecological niche modeling of avian influenza case occurrences in Middle Eastern poultry

International Journal of Health Geographics, 2011
Background Ecological niche modeling integrates known sites of occurrence of species or phenomena with data on environmental variation across landscapes to infer environmental spaces potentially inhabited (i.e., the ecological niche) to generate ...

Immigration, local dispersal limitation, and the repeatability of community composition under neutral and niche dynamics. [PDF]

PLoS ONE, 2012
Repeatability of community composition has been a critical aspect for community structure, which is closely associated with community stability, predictability, conservation biology and ecological restoration.

Evaluating the ecological realism of plant species distribution models with ecological indicator values [PDF]

, 2020
Species distribution models (SDMs) are routinely applied to assess current as well as future species distributions, for example to assess impacts of future environmental change on biodiversity or to underpin conservation planning.

Do Ecological Niche Model Predictions Reflect the Adaptive Landscape of Species?: A Test Using Myristica malabarica Lam., an Endemic Tree in the Western Ghats, India

PLoS ONE, 2013
Ecological niche models (ENM) have become a popular tool to define and predict the “ecological niche” of a species. An implicit assumption of the ENMs is that the predicted ecological niche of a species actually reflects the adaptive landscape of the ...

Regional Variation Exaggerates Ecological Divergence in Niche Models [PDF]

Systematic Biology, 2010
Traditionally, the goal of systematics has been to produce classifications that are both strongly supported and biologically meaningful. In recent years several authors have advocated complementing phylogenetic analyses with measures of another form of evolutionary change, ecological divergence. These analyses frequently rely on ecological niche models
