Environmental heterogeneity shapes the C and S cycling-associated microbial community in Haima's cold seeps [PDF]

open access: yesFrontiers in Microbiology, 2023
Environmental heterogeneity in cold seeps is usually reflected by different faunal aggregates. The sediment microbiome, especially the geochemical cycling-associated communities, sustains the ecosystem through chemosynthesis.

Similar fish species composition despite larger environmental heterogeneity during severe hypoxia in a coastal ecosystem [PDF]

open access: yesEcology and Evolution, 2022
Environmental heterogeneity is one of the most influential factors that create compositional variation among local communities. Greater compositional variation is expected when an environmental gradient encompasses the most severe conditions where ...

Structural modifications in Bermuda grass [Cynodon dactylon (L.) Pers.] ecotypes for adaptation to environmental heterogeneity [PDF]

open access: yesFrontiers in Plant Science, 2023
IntroductionIt is well known that different ecotypes adopt different mechanisms to survive under environmental stress conditions. In this regard, each ecotype showed different type of modifications for their existence in a specific habitat that reflects ...

Environmental heterogeneity and commodity sharing in smallholder agroecosystems. [PDF]

open access: yesPLoS One, 2020
Smallholder farmers undertake a number of strategies to cope with climate shocks in a community. The sharing of resources across households constitutes one coping mechanism when environmental shocks differentially impact households. This paper investigates commodity sharing dynamics among households in eight communities in an environmentally ...

Environmental factors determining the diversity of darkling beetles (Coleoptera: Tenebrionidae) in arid, high-altitude environments in Northwestern Argentina [PDF]

open access: yesAnais da Academia Brasileira de Ciências, 2022
Factors influencing the diversity of tenebrionid beetles in arid, high-altitude environments in the northwest of Argentina are little-known. Using pitfall traps and suction sampling in 30 sites, we collected these beetles in Altos Andes (AA) and Puna (PU)

Species richness-environment relationships of European arthropods at two spatial grains : habitats and countries [PDF]

open access: yes, 2012
We study how species richness of arthropods relates to theories concerning net primary productivity, ambient energy, water-energy dynamics and spatial environmental heterogeneity.

Effects of Habitat Heterogeneity and Topographic Variation on Insect Pest Risks in Alpine Regions

open access: yesLand, 2023
Insect pests pose a significant threat to alpine ecosystems, especially under rapid environmental change conditions. Therefore, it is necessary to explore the effects of environmental factors on insect pest risks and provide methods for pest management ...

Habitat associations of woody plant species in evergreen–deciduous broadleaf karst forests in southwest China

open access: yesFrontiers in Ecology and Evolution, 2023
The effects of habitat filtering on community assembly have been extensively researched, and topography has been identified as a critical factor influencing the spatial distribution of trees. In this study, a 25-ha plot was established in karst evergreen–

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.

Heterogeneous responsiveness to environmental stimuli*

open access: yesBehavioral Ecology, 2023
AbstractIndividuals 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: Thecoexistenceof different degrees of responsiveness within one species; theconsistencyof an individual’s degree of ...
