Mechanisms of group‐hunting in vertebrates

ABSTRACT Group‐hunting is ubiquitous across animal taxa and has received considerable attention in the context of its functions. By contrast much less known about mechanisms by which grouping predators hunt their prey. This primarily due to a lack experimental manipulation alongside logistical difficulties quantifying behaviour multiple at high spatiotemporal resolution as they search, select, capture wild However, use new remote‐sensing technologies broadening focal beyond apex provides researchers with great opportunity discern accurately how together not just whether doing so hunters per capita benefit. We incorporate many ideas from collective locomotion throughout this review make testable predictions for future pay particular role that computer simulation can play feedback loop empirical data collection. Our literature showed breadth predator:prey size ratios among be considered group very large (<10 0 >10 2 ). therefore synthesised respect these found promoted different hunting mechanisms. Additionally, are also related stages (search, selection, capture) thus we structure our accordance two factors (stage ratio). identify several novel group‐hunting largely untested, particularly under field conditions, highlight range potential study organisms amenable testing connection tracking technology. believe combination hypotheses, systems methodological approaches should help push directions.

What's going to be on the menu with global environmental changes?

Global Change Biology, Journal Year: 2023, Volume and Issue: 29(20), P. 5744 - 5759

Published: July 17, 2023

Ongoing anthropogenic change is altering the planet at an unprecedented rate, threatening biodiversity, and ecosystem functioning. Species are responding to abiotic pressures both individual population levels, with changes affecting trophic interactions through consumptive pathways. Collectively, these impacts alter goods services that natural ecosystems will provide society, as well persistence of all species. Here, we describe physiological behavioral responses species global on levels result in detectable diet across terrestrial marine ecosystems. We illustrate shifts dynamics food webs implications for animal communities. Additionally, highlight myriad tools available researchers investigate consumption patterns interactions, arguing data a crucial component ecological studies change. suggest holistic approach integrating complexities choice environmental drivers may be more robust resolving trends predicting web responses, potentially identifying early warning signs diversity loss. Ultimately, despite growing body long-term datasets, there remains dearth ecology temporal scales, shortcoming must resolved elucidate vulnerabilities changing biophysical conditions.

Genetic structure and common ancestry expose the dingo-dog hybrid myth

Evolution Letters, Journal Year: 2024, Volume and Issue: 9(1), P. 1 - 12

Published: Oct. 19, 2024

Abstract The evolutionary history of canids has been shown to be complex, with hybridization and domestication confounding our understanding speciation among various canid lineages. dingo is a recent lineage that was completely isolated from other for over 5000 years on the Australian mainland, but introduction domestic dogs in 1788 placed doubt its independence, studies highlighting between dingoes dogs. Using genomic single nucleotide polymorphism data 434 samples, we explicitly test introgression closely related groups dingoes. We found no evidence show previous work likely mischaracterized shared ancestral genetic variation as hybridization. Further, New Guinea Singing Dogs are only group significantly dingoes, which fits phylogenetic analyses. Despite more sympatric distributions dogs, have maintained their independence since arrival Australia, even areas high lethal control, indicating trajectory currently being conserved. future conservation will require policies promote coexistence pathways humans protect rangeland systems dingoes’ future.
