Trophic position determines the persistence of neotropical understory birds after forest disturbance
Ecology and EvolutionHabitat loss and degradation are key drivers of the current biodiversity crisis. Most research focuses on the question of which traits allow species to persist in degraded habitats.

Chironomidae larvae (Diptera) of Neotropical floodplain: overlap niche in different habitats
Brazilian Journal of BiologyThe niche overlap between trophic groups of Chironomidae larvae in different habitats was observed between trophic groups and between different environments in Neotropical floodplain.

Variation of the stable isotope niches of native amphibians in ponds invaded by the red swamp crayfish [PDF]
NeoBiotaRelationships between native and invasive species can modify trophic interactions in food webs and the diet of native species, leading to substantial changes in their trophic niches.

Journal of Threatened Taxa, 2020 The penaeid shrimp Xiphopenaeus kroyeri is the second most important species of crustacean in Brazilian fisheries. Stable isotopes of carbon and nitrogen are chemical proxies to provide quantitative information about the consumer isotopic niche, which is

On the methodology of feeding ecology in fish [PDF]
, 2016 Feeding ecology explains predator’s preference to some preys over others in their habitat and their competitions thereof. The subject, as a functional and applied biology, is highly neglected, and in case of fish, a uniform and consistent ...

Advanced Science, EarlyView.This study elucidates a novel mechanistic role of the deubiquitinase OTUD6A in asthma pathogenesis, uncovering its regulatory function in airway inflammation and airway remodeling through the stabilization of hResistin/mRELMα. This study offers a novel regulatory axis (OTUD6A‐hResistin/mRELMα) in asthma pathogenesis and OTUD6A inhibition as a potential

Ecological speciation in a generalist consumer expands the trophic niche of a dominant predator
Scientific Reports, 2017 Ecological speciation – whereby an ancestral founder species diversifies to fill vacant niches – is a phenomenon characteristic of newly formed ecosystems. Despite such ubiquity, ecosystem-level effects of such divergence remain poorly understood.

Advanced Science, EarlyView.In non‐MASH‐HCC, L‐carnitine promotes tumor progression primarily through its classical role in enhancing fatty acid oxidation (FAO). However, in MASH‐HCC, where FAO is markedly suppressed, L‐carnitine shifts from this canonical function to serve instead as an intracellular acetyl group buffer.

Species traits and the form of individual species–energy relationships [PDF]
, 2006 Environmental energy availability explains much of the spatial variation in species richness at regional scales. While numerous mechanisms that may drive such total species–energy relationships have been identified, knowledge of their relative ...

The Anatomical Record, EarlyView.Abstract The complex evolutionary history behind modern mammalian chewing performance and hearing function is a result of several changes in the entire skeletomuscular system of the skull and lower jaw. Lately, exciting multifunctional 3D analytical methods and kinematic simulations of feeding functions in both modern and fossil mammals and their ...
