Complementary genomic and epigenomic adaptation to environmental heterogeneity [PDF]

open access: yesMolecular Ecology, 2021
AbstractWhile adaptation is commonly thought to result from selection on DNA sequence‐based variation, recent studies have highlighted an analogous epigenetic component as well. However, the relative roles of these mechanisms in facilitating population persistence under environmental heterogeneity remain unclear.

Local and landscape environmental heterogeneity drive ant community structure in temperate seminatural upland grasslands. [PDF]

open access: yesEcol Evol, 2023
Environmental heterogeneity is an important driver of ecological communities. Here, we assessed the effects of local and landscape spatial environmental heterogeneity on ant community structure in temperate semi-natural upland grasslands of Central ...

Heterogeneous responsiveness to environmental stimuli *

open access: yesBehavioral Ecology, 2023
Abstract Individuals of a species cope with environmental variability through behavioral adjustments driven by individuals’ responsiveness to environmental stimuli. Three key empirical observations have been made for many animal species: The coexistence of different degrees of ...

The Bogert Effect and environmental heterogeneity [PDF]

open access: yesOecologia, 2019
A classic question in evolutionary biology is whether behavioral flexibility hastens or hinders evolutionary change. The latter idea, that behavior reduces the number of environmental states experienced by an organism and buffers that organism against selection, has been dubbed the "Bogert Effect" after Charles Bogert, the biologist who first ...

Environmental fitness heterogeneity in the Moran process [PDF]

open access: yesRoyal Society Open Science, 2019
Many mathematical models of evolution assume that all individuals experience the same environment. Here, we study the Moran process in heterogeneous environments. The population is of finite size with two competing types, which are exposed to a fixed number of environmental conditions.

ENVIRONMENTAL HETEROGENEITY ENHANCES CLONAL INTERFERENCE [PDF]

open access: yesEvolution, 2008
Clonal interference (CI) is a phenomenon that may be important in several asexual microbes. It occurs when population sizes are large and mutation rates to new beneficial alleles are of significant magnitude. Here we explore the role of gene flow and spatial heterogeneity in selection strength in the adaptation of asexuals.

EFFECTS OF ENVIRONMENTAL HETEROGENEITY ON VICTIM-EXPLOITER COEVOLUTION [PDF]

open access: yesEvolution, 2008
We study victim-exploiter coevolution in a spatially heterogeneous island model. In each species, fitness consequences of between-species interactions are controlled by a single haploid diallelic locus. Our emphasis is on the conditions for the maintenance of genetic variation, the dynamic patterns observed, the extent of local adaptation and genetic ...

Seasonal and habitat structure of an anuran assemblage in a semideciduous forest area in Southeast Brazil [PDF]

open access: yesAnais da Academia Brasileira de Ciências
In this study, we evaluated the reproductive activity and the temporal and spatial distributions of anuran assemblages in three environments within a semideciduous forest in Southeast Brazil, located at Municipality of Barão de Monte Alto, State of Minas

Prediction of breeding values and selection responses with genetic heterogeneity of environmental variance [PDF]

open access: yes, 2007
There is empirical evidence that genotypes differ not only in mean, but also in environmental variance of the traits they affect. Genetic heterogeneity of environmental variance may indicate genetic differences in environmental sensitivity.
