Natal philopatry, or delayed dispersal of sexually mature offspring, may be due to ecological constraints on dispersal. In this study, we manipulated the population density prairie voles (Microtus ochrogaster) living in experimental outdoor enclosures test a prediction from habitat saturation hypothesis that philopatry and subsequent group formation cooperatively breeding mammal is affected by availability suitable territories. We detected significant, positive relationship between...
Social interactions among conspecifics are a fundamental and adaptively significant component of the biology numerous species. Such give rise to group living as well many complex forms cooperation conflict that occur within animal groups. Although previous conceptual models have focused on ecological causes fitness consequences variation in social interactions, recent developments endocrinology, neuroscience, molecular genetics offer exciting opportunities develop more integrated research...
Abstract Variation in animal space use patterns may be linked to numerous ecological factors affecting survival and reproduction. We examined the relationship between ecology above‐ below‐ground components of by Octodon degus , a semi‐fossorial rodent Chile. monitored daytime minimum convex polygon adaptive kernel range areas 26 individuals determined number burrow systems used during night‐time radiotelemetry trapping on two study grids at Rinconada de Maipú, semi‐arid Matorral central...
Abstract It has been hypothesized that animal groups in socially cohesive species are inherently unstable, ultimately the result of constraints to independent breeding, and proximately product adult fidelity offspring philopatry. Other processes, including emigration individuals join pre‐existing would be less important. We examined persistence variation composition members social Octodon degus , a communal breeding rodent which limitations obvious. This analysis was conducted during...
Variation in sociality may have an important impact on population genetic structure. In highly social species, the formation of kin clusters leads to decreasing variation within but increasing among groups. Studies less species which groups be more short lived revealed a greater diversity consequences structure populations. Thus, studies populations can precisely highlight how and covary wild We explored relationship between natal dispersal structuring (i.e., whether group are composed kin)...
Sociality and cooperative rearing may have evolved to increase direct fitness when conditions are challenging reproduction and/or reduce environmentally induced variance in fecundity. Examination of these hypotheses comes mostly from studies on singularly breeding birds where is monopolized by a male–female adult pair. Instead, little known about plurally species most group members breed rear their offspring communally. We used data an 8-year field study explore the relationship between...
Summary Group size may influence fitness benefits and costs that emerge from cooperative competitive interactions in social species. However, evidence plural breeding mammals indicates group is insufficient to explain variation direct fitness, implying other attributes of groups were overlooked. We studied the natural population a rodent during 5 years test hypothesis stability – terms composition modulates effects increasing number females (a proxy communal rearing) males on offspring...
Explaining the evolution of primate social organization has been fundamental to understand human sociality and more broadly. It often suggested that ancestor all primates was solitary other forms evolved later, with transitions being driven by various life history traits ecological factors. However, recent research showed many understudied species previously assumed be actually live in pairs, intraspecific variation is common. We built a detailed database from primary field studies...
Abstract Theoretical and some empirical evidence suggest that the population dynamics of cooperative breeders (i.e. species with groups including non‐reproductive individuals raise offspring dominant breeders) are more likely to exhibit Allee effects at level social rather than level. However, extent which these similar in where breeding is plural, group members communally rear their remains unclear. Such may still be subject demographic population‐level. Using a 15‐year dataset, we examined...
Some species exhibit physiological and behavioral plasticity to survive adverse periods, such as changing climates or reduced food availability. Yet, during extreme climatic events the mechanisms respond these periods may not be sufficient, potentially driving local population extinctions. We studied dynamics of a common degu (Octodon degus) in central Chile using 12-year long dataset (2009-2020) investigated what environmental factors affected recruitment, survival growth. Our study period...
Both breeding activity and abundance quality of available food are expected to influence daily movements animals. Animals predicted range over large areas meet high energy demands associated with reproduction (females) or increase mating success (males). However, animals should expand their whenever conditions deteriorate. To examine the extent which versus availability space use, we compared size location (home ranges) degu (Octodon degus), a diurnal rodent from semiarid environments...
Long-term individual-based field studies are essential for understanding how animals adapted to their natural environment and they will adapt in the future. conducted on more than 200 mammalian species have accumulated 11,000 study years covered 17,000 generations. They been dominated by social systems population biology, with little research ecophysiology—typically, ecophysiological short-term projects embedded long-term studies. However, physiological data necessary mammals respond rapid...
Abstract Many species show intraspecific variation in their social organization ( IVSO ), which means the composition of groups can change between solitary living, pair or living groups. Understanding is important because it demonstrates resilience to environmental and help us study ultimate proximate reasons for group by comparing group‐living individuals a single species. It has long been realized that environment plays key role explaining occurrence . expected have evolved variable...
