EVOLUTIONARY CONSTRAINT AND ECOLOGICAL CONSEQUENCES [PDF]

Evolution, 2010
One of the most important shifts in evolutionary biology in the past 50 years is an increased recognition of sluggish evolution and failures to adapt, which seem paradoxical in view of abundant genetic variation and many instances of rapid local adaptation.

The ecological and evolutionary consequences of tropicalisation [PDF]

Trends in Ecology & Evolution
Tropicalisation is a marine phenomenon arising from contemporary climate change, and is characterised by the range expansion of tropical/subtropical species and the retraction of temperate species. Tropicalisation occurs globally and can be detected in both tropical/temperate transition zones and temperate regions.

Genomic consequences of ecological speciation in astyanax cavefish. [PDF]

PLoS ONE, 2013
The cave environment is consistently radically different than the surface environment because it lacks light, and animals adapting to cave life are subject to strong selective forces much different than those experienced by their ancestors who evolved in

Ecological and biogeographical consequences of the fragmentation process [PDF]

Glasnik Srpskog Geografskog Društva, 2012
This paper will analyze the cause of, and ecological and biogeographical consequences of fragmentation process of habitats and ecosystems. Fragmentation process of the autochthonous habitats that without doubt leads also towards the break in their ...

Extraordinary sex ratios: cultural effects on ecological consequences. [PDF]

PLoS ONE, 2012
We model sex-structured population dynamics to analyze pairwise competition between groups differing both genetically and culturally. A sex-ratio allele is expressed in the heterogametic sex only, so that assumptions of Fisher's analysis do not apply ...

Evaluating the metapopulation consequences of ecological traps [PDF]

Proceedings of the Royal Society B: Biological Sciences, 2015
Ecological traps occur when environmental changes cause maladaptive habitat selection. Despite their relevance to metapopulations, ecological traps have been studied predominantly at local scales. How these local impacts scale up to affect the dynamics of spatially structured metapopulations in heterogeneous landscapes remains unexplored.

Ecological consequences of sediment on high-energy coral reefs. [PDF]

PLoS ONE, 2013
Sediments are widely accepted as a threat to coral reefs but our understanding of their ecological impacts is limited. Evidence has suggested that benthic sediments bound within the epilithic algal matrix (EAM) suppress reef fish herbivory, a key ...

Ecological and conceptual consequences of Arctic pollution [PDF]

Ecology Letters, 2020
Abstract Although the effect of pollution on forest health and decline received much attention in the 1980s, it has not been considered to explain the ‘Divergence Problem’ in dendroclimatology; a decoupling of tree growth from rising air temperatures since the 1970s.

Biogeochemical versus ecological consequences of modeled ocean physics [PDF]

Biogeosciences, 2017
We present a systematic study of the differences generated by coupling the same ecological–biogeochemical model to a 1°, coarse-resolution, and 1∕6°, eddy-permitting, global ocean circulation model to (a) biogeochemistry (e.g., primary production) and

Statistical Estimation of the Influence of Individual Factors on Emissions from Agricultural Enterprises of Zhytomyr region [PDF]

Problemi Ekonomiki, 2018
The current state of environmental issues in our country, in particular those concerning statistical estimation of the environmental consequences of agricultural activities of enterprises, requires developing and implementing new approaches to ...
