Male sociality along with solitary females is rare in mammals, but it can provide unique insights into the evolution of sociality and cooperation. Because males compete with each other over females, male cooperation in mammals has been explained by joint defense of females against other males. Here, we demonstrate that the benefits of male cooperative hunting can play a major role in shaping sociality. By quantifying differences in morphology, activity, diet, and mating success, we show that in Madagascar’s top predator, the fosa ( Cryptoprocta ferox ), some males associate to jointly hunt large prey, which allows them to grow bigger than both solitary males and females. These associated males’ physical superiority also represents an advantage in contest competition for females, as reflected by higher mating success. Our results demonstrate that enhanced access to food resources by cooperative hunting is a key to physical development and competitiveness in fosas. In contrast to previous findings, we show that male sociality must not be limited to joint defense of territory and females, but that cooperation in food acquisition can favor sociality in sexually dimorphic species."],["dc.identifier.doi","10.1093/beheco/ars150"],["dc.identifier.gro","3150843"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/7637"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.relation.issn","1465-7279"],["dc.subject","cooperative hunting; Cryptoprocta ferox; evolution of group-living; fosa; Madagascar mongoose; male sociality; male–male competition"],["dc.title","Strength in numbers: males in a carnivore grow bigger when they associate and hunt cooperatively"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","no"],["dspace.entity.type","Publication"]]

Spatial memory allows animals to find a goal, such as a productive feeding patch, even when there are no goal-specific sensory cues available. Because there is little experimental information on learning and memory capabilities in free-ranging primates, the aim of this study was to test whether grey mouse lemurs (Microcebus murinus), as short-term dietary specialists, rely on spatial memory in relocating productive feeding sites. In addition, we asked what kind of spatial representation might underlie their orientation in their natural environment. Using an experimental approach, we set eight radio-collared grey mouse lemurs a memory task by confronting them with two different spatial patterns of baited and non-baited artificial feeding stations under exclusion of sensory cues. Positional data were recorded by focal animal observations within a grid system of small foot trails. A change in the baiting pattern revealed that grey mouse lemurs primarily used spatial cues to relocate baited feeding stations and that they were able to rapidly learn a new spatial arrangement. Spatially concentrated, non-random movements revealed preliminary evidence for a route-based restriction in mouse lemur space; during a subsequent release experiment, however, we found high travel efficiency in directed movements. We therefore propose that mouse lemur spatial memory is based on some kind of mental representation that is more detailed than a route-based network map."],["dc.identifier.doi","10.1007/s10071-009-0219-y"],["dc.identifier.gro","3150855"],["dc.identifier.pmid","19263100"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?goescholar/3567"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/7649"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","final"],["dc.relation.issn","1435-9448"],["dc.rights","Goescholar"],["dc.rights.uri","https://goescholar.uni-goettingen.de/licenses"],["dc.subject","Spatial cognition; Topological map; Euclidean map; Correlated random walk; Goal-directed movement; Microcebus murinus"],["dc.title","Spatial memory in the grey mouse lemur (Microcebus murinus)"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","no"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

A prerequisite to our understanding of lemur biogeography is high-resolution spatial data based on homogenous sampling effort across the island. Although the distribution of lemurs is comparatively well documented, some areas of Madagascar have been poorly surveyed. Among these zones is the large zone of microendemism between the Tsiribihina and the Betsiboka Rivers in western Madagascar. Here, we add new data on the distribution of several less known lemur species in this area. Two rapid lemur surveys in combination with hitherto unpublished information confirms the presence of at least 11 primate species from all five lemur families in the Beanka Forest - an isolated fragment of dry deciduous forest on limestone close to Maintirano. This level of species diversity is considerable and exceeds most other dry deciduous forests on the island. The specific determinations of Cheirogaleus sp. indet., Lepilemur cf. randrianasoli, Hapalemur cf. griseus ranomafanensis, and Mirza sp. in the Beanka Forest need to be supported by morphological and genetic data. Overall, lemur distribution in the surveyed zone of microendemism only partly supports the centers-of-endemism hypothesis. Given its extraordinarily high lemur diversity, the Beanka Forest deserves more attention from researchers studying lemur ecology and behavior. Current programs of Biodiversity Conservation Madagascar are important for the conservation of this forest area."],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/10024"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.relation.ispartof","The Beanka Forest, Melaky Region, western Madagascar"],["dc.title","Lemurs of the Beanka Forest, Melaky Region, western Madagascar"],["dc.type","book_chapter"],["dc.type.internalPublication","unknown"],["dspace.entity.type","Publication"]]
