Methodological constraints for the stable isotope analysis of different tissues: A comparison between muscle and whole‐body samples in freshwater gammarids

Limnology and Oceanography: Methods, EarlyView.
Abstract Carbon (δ13C) and nitrogen (δ15N) stable isotope ratios allow the reconstruction of food webs, provided that all trophic levels are properly characterized. In freshwater ecosystems, small‐bodied invertebrates often occupy central positions in food webs, with whole‐body samples commonly used for their stable isotope analysis, due to ...

Structural variation in the brown alga Sargassum cymosum and its effects on associated amphipod assemblages

Brazilian Journal of Biology
The presence of diverse biological substrates adds complexity to coastal landscapes and increases the number of ecological niches that can be used by the mobile epifauna. Studies on the influence of structural complexity have focused mainly on algal host

Dynamic response of communities and ecosystem functions to ecosystem engineering and multiple stressors in a marine mussel bed

Oikos, EarlyView.
Ecosystem engineers are crucial to the development of coastal ecosystem communities and functions. However, a better understanding of how environmental stressors affect ecosystem engineering and thereby influence communities and ecosystem dynamics is needed. We conducted an in situ experiment in a blue mussel Mytilus spp.

Food composition of a breeding population of the endemic Anatolia newt, Neurergus strauchii (Steindachner, 1887) (Caudata: Salamandridae), from Bingöl, Eastern Turkey

Acta Herpetologica, 2020
The study presents data on the food composition of a breeding population of the Anatolia newt Neurergus strauchii (Steindachner, 1887), from Bingöl, Turkey. A total of 953 prey items were determined in the food contents of 46 individuals (18 males and 28

Warming modifies trophic impacts of invading shrimp with impact varying among primary producers

Oikos, EarlyView.
Environmental change drivers, such as climate change and species invasions, can disrupt biological networks and weaken ecosystem stability. Acting together, these drivers may interact and alter the effects on the ecosystem. However, few studies have examined the interactive effects of climate change and species invasions, particularly in aquatic ...

Artemia salina Toxicity Assay: Standardization in a 24‐Well Microplate

Environmental Toxicology, EarlyView.
ABSTRACT Bioassays with Artemia sp. are widely used in aquatic, environmental, and human toxicology as an initial tool to investigate the toxicity of plant extracts, isolated compounds, drugs, and products of natural or synthetic origin. These assays allow for the estimation of the median lethal concentration (LC50) and guide subsequent studies in ...

Invasive goldfish trigger a regime shift in experimental lake ecosystems of varying trophic state

Journal of Animal Ecology, EarlyView.
The pet trade distributes exotic animals around the globe that enrich human lives. However, some pets become pests when released into the wild. This study provides experimental evidence that goldfish will negatively affect native freshwater organisms and ecosystems.

Geographic Patterns of Head Morphology in Syngnathus typhle Across Marine Regions

Integrative Zoology, EarlyView.
Morphometric analysis of Syngnathus typhle head shape shows distinct geographic patterns across Baltic, North, Atlantic, and Mediterranean marine regions, driven by variation in snout length, head depth, and eye position. Findings provide a non‐invasive baseline for conservation monitoring.
