Abstract Background Access to critical resources, including food, water, or shelter, significantly determines individual fitness. As these resources are limited in most habitats, animals may employ strategies of landscape partitioning mitigate the impact direct resource competition. Territoriality be regarded as an aggressive form partitioning, but other forms exist non-territorial species. Animals living groups with greater flexibility their association patterns, such multilevel societies fission–fusion dynamics, adjust grouping and space use patterns short-term variations ecological conditions food availability, predation pressure, presence conspecific groups. This allow them balance costs competition while reaping benefits better predator detection defence. Methods We explored among neighbouring Guinea baboon ( Papio papio ) parties Niokolo-Koba National Park, Senegal. baboons live a society which predictably higher-level associations (“gangs”). used four years locational data from individuals equipped GPS collars estimate annual home ranges, range overlap, average minimum distances between parties. examined whether availability levels affected cohesion 2022. Results found substantial overlap core area (33 100%). Food did not affect distance closest party; was less than 100 m. Conclusions Our results suggest low level feeding our study Whether this is general feature particular situation Park remains investigated.

Abstract Foraging is a key driver of animal movement patterns, with specific challenges for predators which must search mobile prey. These patterns are increasingly impacted by global changes, principally in land use and climate. Understanding the degree flexibility predator foraging social strategies pertinent to wildlife conservation under change, including potential top-down effects on wider ecosystems. Here we propose future research directions better understand predators. In particular, rapid continued advances biologging technology helping record dynamic behavioural responses animals environmental their energetic consequences. Data collection can be optimised calibrating interpretation methods captive settings strategic tagging decisions within between groups. Importantly, many species’ systems being found more flexible than originally described literature, may readily detectable through approaches observation. Integrating physical landscape biotic interactions will explaining predicting movements balance changing world.

Cooperative breeding in birds is thought to be more common altricial species, with few described cases precocial species. However, cooperative may also difficult detect species and could have been overlooked. We investigated whether Vulturine Guineafowl Acryllium vulturinum breed cooperatively and, if so, how care distributed among group members. collected data from 51 uniquely marked individuals (27 males, 24 females), of which 13 females bred at least once over three different seasons. found that broods had close associates comprising both adults subadults exhibited four distinct behaviours: babysitting, chick guarding, covering the chicks calling food. Further, we offspring significantly male‐biased, non‐mother provided most each brood received, differed much help they received carers pay a foraging cost when providing care. In line many other birds, their sons. Our results confirm are plural breeders add growing evidence widespread young than previously thought, thereby counterpoint altriciality–cooperative hypothesis.

However, we seldom ask how each situation contributes to the global structure of a population, whether different situations contribute information about position individuals within fabric.

Abstract Animal social and spatial behaviours are inextricably linked. movements driven by environmental factors interactions. Habitat structure changing patterns of animal space use can also shape Animals adjust their to reduce the risk offspring mortality. In territorial infanticidal species, two strategies possible for males: they stay close protect them against rivals (infant‐defence hypothesis) or patrol territory more intensively prevent rival intrusions (territorial‐defence hypothesis). Here, we tested these hypotheses in African lions ( Panthera leo ) investigating how males females presence offspring. We combined datasets on demography movement lions, collected between 2002 2016 Hwange National Park (Zimbabwe), document cubs (field observations) simultaneous groupmates competitors (GPS tracking). showed a response offspring, with less likely select areas waterholes periphery than without cubs. contrast, were selected when there pride. found responses.

Abstract Integrated step‐selection analysis (ISSA) is frequently used to study habitat selection using animal movement data. Methods for incorporating random effects in ISSA have been developed, making it possible quantify variability among animals their space‐use patterns. Although model both and parameters, applications date focused on the former despite widely acknowledged important role that plays determining ecological processes from individual ecosystem level. One potential explanation this omission absence of readily available software or examples demonstrating methods estimating parameters with effects. We demonstrated characterizing among‐individual habitat‐selection a simulated data set by fitting two models an acoustic telemetry containing locations 35 red snapper ( Lutjanus campechanus ).

While territoriality is one of the key mechanisms influencing carnivore space use, most studies quantify resource selection and movement in absence conspecific influence or territorial structure. Our analysis incorporated social information a framework to investigate intra-specific competition on habitat large, carnivore.

Kin selection is important for understanding the evolution of social behaviour in group-living species. Yet, role kinship solitary species has received little attention. We studied how influences intraspecific variation organization and spatial structure a predominantly species, bush Karoo rat, Otomys unisulcatus, from Succulent semidesert South Africa. predicted that if groups occur, they should consist close kin. further not random, but kin live closer to each other. Over 5 years we performed trapping focal animal observations fitted mini-GPS dataloggers simultaneously on 125 neighbouring female rats investigate their was influenced by kinship. Females were mainly solitary, although small also occurred, all consisting kin, typically females, such as mother her adult daughter or sisters. Although females did have more nonkin than neighbours, lived other nonkin. Daily ranges larger breeding nonbreeding season overlapped between females. conclude be considered when studying it might influence structure.
