Abstract The management and conservation of tuna other transboundary marine species have to date been limited by an incomplete understanding the oceanographic, ecological socioeconomic factors mediating fishery overlap interactions, how these vary across expansive, open ocean habitats. Despite advances in fisheries monitoring biologging technology, few attempts made conduct integrated analyses at basin scales relevant pelagic highly migratory they target. Here, we use vessel tracking data, archival tags, observer records, machine learning examine inter‐ intra‐annual variability (2013–2020) five longline fishing fleets with North Pacific albacore ( Thunnus alalunga , Scombridae). Although progressive declines catch biomass observed over past several decades, is one only stocks primarily targeted longlines not currently listed as overfished or experiencing overfishing. We find that varies significantly time space mediated (1) differences habitat preferences between juvenile adult albacore; (2) variation oceanographic features known aggregate biomass; (3) different spatial niches shallow‐set deep‐set gear. These findings may significant implications for stock assessment this systems, particularly reliance on fishery‐dependent data index abundance.

Abstract Individual decisions regarding how, why and when organisms interact with one another their environment scale up to shape patterns processes in communities. Recent evidence has firmly established the prevalence of intraspecific variation nature its relevance community ecology, yet challenges associated collecting data on large numbers individual conspecifics heterospecifics have hampered integration into ecology. Nevertheless, recent technological statistical advances GPS‐tracking, remote sensing behavioural ecology offer a toolbox for integrating processes. More than simply describing where go, movement provide unique information about interactions environmental associations from which true individual‐to‐community framework can be built. By linking paths both data, ecologists now simultaneously quantify interspecific Eltonian (biotic interactions) Grinnellian (environmental conditions) factors underpinning assemblage dynamics, substantial logistical analytical must addressed these approaches realize full potential. Across communities, empirical support conservation applications reveal metacommunity dynamics via tracking‐based dispersal data. As multi‐species tracking are surmounted, we envision future movements ecological signatures will bring resolution many enduring issues

Abstract Despite growing evidence of widespread impacts humans on animal behaviour, our understanding how reshape species interactions remains limited. Here, we present a framework that draws key concepts from behavioural and community ecology to outline four primary pathways by which can alter predator–prey spatiotemporal overlap. We suggest dyads exhibit similar or opposite responses human activity with distinct outcomes for predator diet, predation rates, population demography trophic cascades. demonstrate assess these response hypothesis testing, using temporal data 178 published camera trap studies terrestrial mammals. found each the proposed pathways, revealing multiple patterns influence Our case study highlight current challenges, gaps, advances in linking behaviour change dynamics.

Some animal species shift their activity towards increased nocturnality in disturbed habitats to avoid predominantly diurnal humans. This may alter diel overlap among species, a precondition most predation and competition interactions that structure food webs. Here, using camera trap data from 10 tropical forest landscapes, we find hyperdiverse Southeast Asian wildlife communities peak early mornings intact dawn dusk (increased crepuscularity). Our results indicate anthropogenic disturbances drive opposing behavioural adaptations based on rarity, size feeding guild, with more the 59 rarer specialists' diurnality for medium-sized generalists, less larger hunted species. Species turnover also played role underpinning community- guild-level responses, associated markedly detections of generalists predators. However, predator-prey or competitor guilds does not vary disturbance, suggesting net be conserved.

Human disturbance may fundamentally alter the way that species interact, a prospect remains poorly understood. We investigated whether anthropogenic landscape modification increases or decreases co-occurrence—a prerequisite for interactions—within wildlife communities. Using 4 y of data from >2,000 camera traps across human gradient in Wisconsin, USA, we considered 74 pairs (classifying as low, medium, high antagonism to account different interaction types) and used time between successive detections measure their co-occurrence probability define networks. Pairs averaged 6.1 [95% CI: 5.3, 6.8] d low-disturbance landscapes (e.g., national forests) but 4.1 [3.5, 4.7] high-disturbance landscapes, such those dominated by urbanization intensive agriculture. Co-occurrence networks showed higher connectance (i.e., larger proportion possible co-occurrences) greater proportions low-antagonism disturbed landscapes. Human-mediated abundance (possibly via resource subsidies) appeared more important than behavioral mechanisms changes daily activity timing) driving these patterns compressed The spatiotemporal compression co-occurrences likely strengthens interactions like competition, predation, infection unless can avoid each other at fine scales.

A better understanding predation can be facilitated by using electronic tags log or transmit positions predator prey species in natural settings, however, there are special considerations must made to avoid biased estimates. We provide an overview the tools available for studying with including tag types analytical used identify where, when how killed predators. also discuss experimental design tags, minimize effects capture tagging procedures. Ongoing innovation integration sensors will more detailed data about performance tagged predators fate prey. Where analysts effectively resolve timing state‐of‐the‐art tools, we foresee exciting advances our animal demographics, evolutionary trajectories management systems.

Abstract Although anthropogenic change is often gradual, the impacts on animal populations may be precipitous if physiological processes create tipping points between energy gain, reproduction or survival. We use 25 years of behavioural, diet and demographic data from elephant seals to characterise their relationships with lifetime fitness. Survival increased mass gain during long foraging trips preceding pupping seasons, there was a threshold where individuals that gained an additional 4.8% body (26 kg, 206 232 kg) reproductive success three‐fold (from 1.8 4.9 pups). This due two‐fold increase in probability (30% 76%) 7% lifespan (6.0 6.4 years). The sharp explain failure observed many species demonstrates how small, gradual reductions prey disturbance could have profound implications for populations.
