Indirect maternal effects via nest microbiome composition drive gut colonization in altricial chicks

Molecular Ecology, Journal Year: 2023, Volume and Issue: 32(13), P. 3657 - 3671

Published: April 25, 2023

Gut microbial communities are complex and heterogeneous play critical roles for animal hosts. Early-life disruptions to microbiome establishment can negatively impact host fitness development. However, the consequences of such early-life remain unknown in wild birds. To help fill this gap, we investigated effect continuous gut on development Great tit (Parus major) Blue (Cyanistes caeruleus) nestlings by applying antibiotics probiotics. Treatment neither affected nestling growth nor their composition. Independent treatment, microbiomes both species grouped brood, which shared highest numbers bacterial taxa with nest environment mother. Although fathers showed different than nests, they still contributed structuring chick microbiomes. Lastly, observed that distance between nests increased inter-brood dissimilarity, but only tits, indicating species-specific foraging behaviour and/or microhabitat influence Overall, strong maternal effect, driven recolonization from vertical transfer microbes during feeding, appears provide resilience towards

Uropygial gland microbiota of nearctic−neotropical migrants vary with season and migration distance

Animal Microbiome, Journal Year: 2025, Volume and Issue: 7(1)

Symbiotic microbiota are important drivers of host behaviour, health, and fitness. While most studies focus on humans, model organisms, domestic or economically species, research investigating the role in wild populations is rapidly accumulating. Most gut microbiota; however, skin other glandular also play an shaping traits that may impact The uropygial gland source chemical cues harbours diverse microbes could mediate communication birds, so determining factors should improve our understanding microbially-mediated communication. Hypothesizing temporal, geographic, taxonomic effects influence microbiota, we evaluated season, migration distance, taxonomy 18 passerine species from 11 families. By sampling 473 birds at a single stopover location during spring fall using 16S rRNA sequencing, demonstrate followed by had strongest microbial community composition. statistically significant, family only weak microbiota.

Abstract Daily light–dark cycles shape the circadian physiology and behaviour of nearly all organisms, with variation in phenotypes having cascading effects on individual fitness, species interactions co‐evolution. Recent evidence that rhythms host immunity metabolism are synchronised by gut microbiota suggest dynamics microbes a crucial component their function.

Prey responses to predation risk under chronic road noise

Journal of Zoology, Journal Year: 2022, Volume and Issue: 317(2), P. 147 - 157

Published: April 5, 2022

Abstract Anthropogenic noise has dramatically increased over the past decades with potentially significant impacts on wildlife and their community interactions. Using giving‐up densities (GUDs) paired camera traps, we examined concurrent influence of chronic road predation risk free‐living small mammals. Specifically, looked for differences in foraging vigilance behavior during various treatments. We found that mammals significantly reduced food intake when exposed to risk; however, exposure eliminated this effect; compared alone. Furthermore, number visits time spent at trays while it risky situations, meaning they were able increase efficiency. Mice also ate less moon illumination was greater; had no effect our overall results. This is one first studies concurrently examine effects prey. It shows complex responses prey conditions as attempt gain reliable information about respond appropriately. highlight potential consequences may have survival interferes appropriate responses.
