Abstract Home range size limits the number of resources an individual can access; hence, it often increases with energy demands. However, maintaining a large home also requires more expenditure, and foraging over larger area decrease search efficiency, especially for central place foragers that travel frequently between base food patches. Consequently, individuals may need to reduce expenditure in other aspects, such as resting metabolic rate (RMR). So far, studies examining relationship RMR are limited. In this study, we investigated whether is correlated bush Karoo rats (Otomys unisulcatus). Using Foxbox mini-GPS dataloggers, measured body mass, (scaled by mass), daily ranges 25 female adult field. As commonly found studies, mass was associated rats. addition, mass-scaled positively size. This suggests provides sufficient support increased required foraging, well higher budget basal biological processes

Abstract There are barriers to directly observing animals that cryptic or live in environments inaccessible humans. Biologgers, animal-attached devices designed collect data on without a human researcher present, have become useful tools for studying species cannot be observed. The use of biologgers has been size-limited until recent efforts miniaturize the technology opened up possibility using them small animals. In this study, we packaged and deployed proximity logging (“ProxLogs” model) small, socially monogamous, semifossorial mammal, Prairie Vole (Microtus ochrogaster), as means high-resolution fine-scale spatial between conspecifics. First, evaluated multiple packaging options found UV-curing epoxy resin containing grit (sand) was most durable material. ProxLogs recorded voles when they were within 6 cm each other. We compared resolution social collected by patterns through livetrapping and, expected, generated significantly higher-resolution than livetrapping. also predicted ProxLogs. Our findings provide proof concept loggers, with resin, reliable, method 24-h mammals otherwise difficult observe.

Many mammal species are thought to adopt solitary living owing mothers becoming intolerant of adult offspring and the occurrence social intolerance between adults. However, field studies on how mammals interact rare. Here we show that can occur without intolerance. Over 3 years, recorded interactions free-living bush Karoo rats (

Abstract In short-lived animals, individuals born earlier in the breeding season frequently reproduce within of birth. Consequently, it has been proposed that those early benefit from a more proactive behavioral type to compete for reproductive resources whereas later-borns adopt reactive personality conserve energy survive through non-breeding and following year. However, being could also acquiring decreasing late season. We investigated differences depending on date birth relation resource variation free-living population bush Karoo rat (Otomys unisulcatus). This species constructs stick lodges, critical protecting rats harsh semi-desert environments, but availability vacant lodges decreases with increasing density during predicted an increased occurrence phenotypes later season, contrasting commonly assumed decrease due lack opportunity. behaviorally phenotyped n= 99 repeated tests found consistent individual along proactive-reactive gradient. Most importantly, showed greater activity, boldness exploration tendencies, indicating personality. addition, among early-born females, which reproduced no compared did not reproduce. Our results indicate seasonal types may be driven by constraints rather than reproduction opportunities.
