Differences in individual locomotor activity patterns may be linked to a number of ecological factors, such as changes ambient temperature or photoperiod. Observations on subterranean mammals suggest that they exhibit diel rhythms despite the lack visual cues their underground burrows, but it is unknown how seasonality and characteristics affect activity. In this study we use RFID technology monitor daily wild, social Natal mole-rats ( Cryptomys hottentotus natalensis ) during summer winter...
Abstract Cooperation and group living have been suggested to facilitate survival in varying environments under challenging conditions. However, may also be associated with costs, particularly species where individuals within groups compete for limited resources. The costs benefits of cooperative on cooperatively breeding mammals remain unclear. Here, we use data collected from wild, Natal mole‐rats ( Cryptomys hottentotus natalensis ) inhabiting a seasonally environment assess whether body...
Biological investments, such as reproduction, are influenced by both biotic and abiotic factors their interactions. The trade-off between reproduction survival has been well established. Seasonally breeding species, therefore, may exhibit variations in these trade-offs, but there is a dearth of knowledge concerning this. This study investigated the physiological cost (measured through oxidative stress) across seasons cooperatively highveld mole-rat ( Cryptomys hottentotus pretoriae ), one...
Abstract Fluctuating asymmetry, the non-directional deviation from bilateral symmetry resulting developmental instability, can indicate early-life environmental stress. While fluctuating asymmetry affect individual survival and reproductive success, its effect on fitness differs between species. Here, we analyzed up to 27 years of mark-recapture data 894 RFID tagged individuals three forest-living bat species in southern Germany investigate degree forearm length. In Bechstein’s bats, Myotis...
Abstract Selection pressures underpinning the evolution of mammalian sociality and body mass variation have spurred great interest for several decades. Because they inhabit a wide range geographic localities habitats, African mole-rat subspecies Cryptomys hottentotus present unique opportunity to further our understanding intra- interspecific in species. We compared demographics masses among 4 C. subspecies: Mahali mole-rat, h. mahali; highveld pretoriae; Natal natalensis; common within...
