Abundant and Rare Bacterial Taxa Structuring Differently in Sediment and Water in Thermokarst Lakes in the Yellow River Source Area, Qinghai-Tibet Plateau

open access: yesFrontiers in Microbiology, 2022
Thermokarst lakes are forming from permafrost thaw and are severely affected by accelerating climate change. Sediment and water in these lakes are distinct habitats but closely connected. However, our understanding of the differences and linkages between

The declines of heterogeneity and stability in diatom communities are associated with human activity

open access: yesEcology and Evolution, 2023
Anthropogenic forcing caused the biodiversity loss and stability decline of communities. There is still controversy over whether the decline in biodiversity will lead to a decrease in community stability.

Effects of species traits, motif profiles, and environment on spatial variation in multi‐trophic antagonistic networks

open access: yesEcosphere, 2020
Understanding drivers of antagonistic interactions across temporal and spatial scales is important for predicting community structure. In particular, studies examining spatial variation in ecological networks are critical for anticipating community ...

Introgression and rapid species turnover in sympatric damselflies [PDF]

open access: yesBMC Evolutionary Biology, 2011
Studying contemporary hybridization increases our understanding of introgression, adaptation and, ultimately, speciation. The sister species Ischnura elegans and I. graellsii (Odonata: Coenagrionidae) are ecologically, morphologically and genetically similar and hybridize. Recently, I.

Effects of environment and space on species turnover of woody plants across multiple forest dynamic plots in East Asia

open access: yesFrontiers in Plant Science, 2016
Species turnover is fundamental for understanding the mechanisms that influence large-scale species richness patterns. However, few studies have described and interpreted large-scale spatial variation in plant species turnover, and the causes of this ...

Quantifying multiple-site compositional turnover in an Afrotemperate forest, using zeta diversity

open access: yesForest Ecosystems, 2018
Background Species turnover is typically measured by partitioning diversity components into alpha and pairwise beta diversity. However, alpha and beta components cannot express the full spectrum of multiple-site compositional turnover.

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.

Waders (Aves, Charadriiformes) in a Mediterranean remnant wetland: a year-round pilot study evidences contrasting patterns in diversity metrics

open access: yesRivista Italiana di Ornitologia - Research in Ornithology, 2015
Around a yearly cycle (August 2011 - July 2012), we studied the assemblages of waders (Aves Charadriiformes) occurring in a Mediterranean remnant wetland, obtaining a set of diversity metrics.

Environmental Drivers of Mesophotic Echinoderm Assemblages of the Southeastern Pacific Ocean

open access: yesFrontiers in Marine Science, 2021
Mesophotic ecosystems (50–400 m depth) of the southeastern Pacific have rarely been studied because of the logistical challenges in sampling across this remote zone. This study assessed how oxygen concentrations and other environmental predictors explain

Species turnover between the northern and southern part of the South China Sea in the Elaphropeza Macquart mangrove fly communities of Hong Kong and Singapore (Insecta: Diptera: Hybotidae)

open access: yesEuropean Journal of Taxonomy, 2019
A recent survey of the mangroves around Hong Kong revealed the presence of seven species of the genus Elaphropeza Macquart, 1827. All belong to a group of yellow species that occur exclusively in mangroves.
