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 ...

What do We Mean by Environmental Heterogeneity? Toward A Mechanistically Explicit and Scale‐Dependent Framework [PDF]

open access: yesEcology and Evolution
Environmental heterogeneity (EH) is widely recognized as a key driver of biodiversity, yet its conceptual foundations remain insufficiently structured. Here we present a semi‐systematic narrative synthesis of 360 studies retrieved from Web of Science and

The alpine scrubs and dwarf heaths of the Balkan Peninsula - an exceptional center of floristic richness and endemism [PDF]

open access: yesBotanica Serbica, 2023
Alpine scrubs (Roso pendulinae-Pinetea mugo) and dwarf heaths (Loiseleurio procumbentis-Vaccinietea) are an exceptional assemblage of rich floristic units which contribute significantly to the overall diversity on the Balkan Peninsula.

Environmental context alters the magnitude of conspecific negative density dependence in a temperate forest

open access: yesEcosphere, 2021
Conspecific negative density dependence (CNDD) is an important driver of stand‐level tree diversity in temperate forests. CNDD can occur via two main processes.

Genomic Adaptive Evolution of Sand Rice (Agriophyllum squarrosum) and Its Implications for Desert Ecosystem Restoration

open access: yesFrontiers in Genetics, 2021
Natural selection is a significant driver of population divergence and speciation of plants. Due to local adaptation to geographic regions with ecological gradients, plant populations harbored a wide range of adaptive genetic variation to enable them to ...

Clonality drives structural patterns and shapes the community assemblage of the Mediterranean Fagus sylvatica subalpine belt

open access: yesFrontiers in Plant Science, 2022
Past anthropogenic disturbances lowered the altitudinal distribution of the Mediterranean Fagus sylvatica forests below 2,000 m a.s.l. Accordingly, our current understanding of the southern distribution range of F.

Environmental Factors Override Dispersal-Related Factors in Shaping Diatom and Macroinvertebrate Communities Within Stream Networks in China

open access: yesFrontiers in Ecology and Evolution, 2020
Metacommunity theory provides a useful framework to describe the underlying factors (e.g., environmental and dispersal-related factors) influencing community structure.

Microbial community composition in urban riverbank sediments: response to municipal effluents over spatial gradient

open access: yesWater Science and Technology, 2023
Municipal effluents have adverse impacts on the aquatic ecosystem and especially the microbial community. This study described the compositions of sediment bacterial communities in the urban riverbank over the spatial gradient.

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)
