Charophyte variation in sensitivity to eutrophication affects their potential for the trophic and ecological status indication

Knowledge and Management of Aquatic Ecosystems, 2021
Charophytes (stoneworts) form a group of macrophytes that are considered sensitive to eutrophication. The high indicator value of charophytes toward eutrophication results in their wide use in the bioassessment systems.

A classification system for predicting invasiveness using climatic niche traits and global distribution models: application to alien plant species in Chile [PDF]

NeoBiota, 2020
Functional traits that predict plant invasiveness are a central issue in invasion ecology. However, in many cases they are difficult to determine, especially for a large set of species.

Vertical forest strata position and niche shifts between juvenile and adult spiders [PDF]

Biodiversity Data Journal
Functional trait analyses have become a vital part of ecological and evolutionary research in recent years. Nevertheless, this progress highlights the persistent and significant gaps in our knowledge of species traits, a limitation known as the Raunkiæran shortfall.

Niche expansion by indigenous fish species following the introduction of rainbow trout (Oncorhynchus mykiss) in a subtropical river system, upper Blyde River, South Africa

Frontiers in Environmental Science, 2022
The introduction of alien predatory fish such as rainbow trout (Oncorhynchus mykiss) can have a significant effect on indigenous fish communities such as altering the structure and dynamics of food webs.

Position in the climatic niche modulates post-fire performance of Pinus halepensis regeneration

Forest Ecology and Management
Fire is a primary driver in shaping Mediterranean ecosystems, being post-fire regeneration a key process for vegetation dynamics and resilience. However, how climatic variability modulates regeneration success after fire is not fully known. We use Pinus halepensis as a species case study to investigate how local climatic conditions relative to the ...

How does functional distinctiveness affect single species contribution to β diversity? Evidence from a subtropical forest plot in southern China

Ecological Indicators, 2023
To biologically interpret β diversity patterns, in terms of species characteristics, needs to quantify how each individual species contributes to overall β diversity (SCBD).

How vulnerable are bryophytes to climate change? Developing new species and community vulnerability indices

Ecological Indicators, 2022
Species’ vulnerability to climate change is often assessed by focusing on potential changes of species’ ranges. This study aimed to develop community-level vulnerability indices which measure bryophyte community vulnerability to climate change, based on ...

A hypothesis-testing framework for studies investigating ontogenetic niche shifts using stable isotope ratios. [PDF]

PLoS ONE, 2011
Ontogenetic niche shifts occur across diverse taxonomic groups, and can have critical implications for population dynamics, community structure, and ecosystem function.

Comparison of Trophic Niche Position, Size, and Overlap in an Assemblage of Pacific Rockfish (Genus Sebastes) for Testing Community Composition Models

Diversity, 2022
Rockfish (genus Sebastes) assemblages can inform mechanisms of coexistence and maintenance of diversity in ecological communities. Coexistence theory characterizes ecological assemblages as following either a deterministic niche differentiation model, or
