Assembly mechanism of macroinvertebrate metacommunities and ecological factors of multiple aspects of beta diversity in a boreal river basin, China

Frontiers in Ecology and Evolution, 2023
The emergence of metacommunity theory has significantly contributed to our understanding of the drivers of community assembly and biome variation. The Network Location Hypothesis (NPH) posits that tributary communities situated at the source regions of a

Species packing and the latitudinal gradient in beta-diversity [PDF]

Proceedings of the Royal Society B: Biological Sciences, 2020
Abstract The decline in species richness at higher latitudes is among the most fundamental patterns in ecology. Whether changes in species composition across space (beta-diversity) contribute to this gradient of overall species richness (gamma-diversity) remains hotly debated.

Scale dependence of the beta diversity-scale relationship [PDF]

, 2015
Alpha, beta, and gamma diversity are three fundamental biodiversity components in ecology, but most studies focus only on the scale issues of the alpha or gamma diversity component.

An operational, additive framework for species diversity partitioning and beta‐diversity analysis [PDF]

Journal of Ecology, 2007
Summary An important goal of community ecology is the assessment of factors that are likely to influence the spatio‐temporal distribution of species assemblages and diversity. Surprisingly, most statistical methods devoted to this have remained poorly interconnected, as well as poorly connected with the popular metrics of diversity estimation.

Time Toxicity in Wilms Tumor: Quantifying the Burden of Healthcare Interaction in the First Year After Diagnosis

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Wilms tumor (WT) treatment imposes a significant time burden on patients and their families. Time toxicity is a patient‐centered metric that quantifies the burden of healthcare interaction. We sought to define time toxicity in the first year after diagnosis of WT and hypothesized that it would increase as tumor stage and treatment ...

Species richness and beta diversity patterns of multiple taxa along an elevational gradient in pastured grasslands in the European Alps

Scientific Reports, 2020
To understand how diversity is distributed in space is a fundamental aim for optimizing future species and community conservation. We examined in parallel species richness and beta diversity components of nine taxonomic groups along a finite space ...

Navigating the spatial and temporal aspects of beta diversity to clarify understanding biodiversity change

Global Ecology and Conservation
Beta diversity is often assessed at different spatial and temporal scales and, consequently, has been defined in multiple ways. Here, we define four unique aspects of beta diversity that encompass the diverse applications of this concept in ecology and ...

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)
