Although the family Hyaenidae contains only four living species, and is therefore one of the smallest among mammalian carnivores, it is remarkable for its ecological and social diversity, which surpasses that of much larger families such as canids and felids. The four extant hyena species represent the last remnants of a family that was once large and diverse. At the peak of hyaenid diversity in the Late Miocene (12–6 million years ago), at least 24 different hyena species concurrently roamed… Expand
Ecological specialisation and evolutionary reticulation in extant Hyaenidae
TLDR
Genes related to immunity and digestion in the bone-cracking hyenas and craniofacial development in the aardwolf showed the strongest signals of selection in their respective lineages, suggesting putative key adaptations to carrion or termite feeding. Expand
Ecological Specialization and Evolutionary Reticulation in Extant Hyaenidae
TLDR
Genes related to immunity and digestion in the bone-cracking hyenas and craniofacial development in the aardwolf showed the strongest signals of selection, suggesting putative key adaptations to carrion and termite feeding, respectively. Expand
Population and conservation genomics of the world's rarest hyena species, the brown hyena (Parahyena brunnea)
TLDR
Brown hyenas harbour the lowest genetic diversity for a species on both the mitochondrial and nuclear level when compared to a number of mammalian species for which such information is currently available, and this could be the result of a continuous and ongoing decline in effective population size.

Habitat preference indicators for striped hyena (Hyaena hyaena) in Nepal
Abstract The striped hyena (Hyaena hyaena Linnaeus, 1758) is one of the large carnivores of forest and grassland ecosystems across Africa and Asia and is currently threatened throughout its range.Expand
Pasting Behaviour Suggests Cryptic Sociality in the Striped Hyaena, Hyaena hyaena
TLDR
It was found that pasting did not function to control food or den resources, and there was no evidence that females pasted to demarcate territories, in striped hyaenas. Expand
Palaeoproteomic analysis of Pleistocene cave hyenas from east Asia
TLDR
This marks the first proteomic data generated from cave hyenas, adding new molecular data to the east Asian populations of Crocuta, and reveals two different groups of cave Hyenas in east Asia. Expand
Pleistocene Chinese cave hyenas and the recent Eurasian history of the spotted hyena, Crocuta crocuta
The living hyena species (spotted, brown, striped and aardwolf) are remnants of a formerly diverse group of more than 80 fossil species, which peaked in diversity in the Late Miocene (about 7–8 Ma).Expand
Ancient mitochondrial genomes from Chinese cave hyenas provide insights into the evolutionary history of the genus Crocuta
TLDR
Near-complete mitochondrial genomes from two cave hyenas from northeastern China are assembled, representing the youngest directly dated fossils of Crocuta in Asia and a monophyletic clade of these two samples within a deeply diverging mitochondrial haplogroup of Cro cuta is suggested. Expand
Extended and Continuous Decline in Effective Population Size Results in Low Genomic Diversity in the World’s Rarest Hyena Species, the Brown Hyena
TLDR
It is found that brown hyena harbor extremely low genetic diversity on both the mitochondrial and nuclear level, most likely resulting from a continuous and ongoing decline in effective population size that started ˜1 Ma and dramatically accelerated towards the end of the Pleistocene. Expand
The ecology of spotted hyena,Crocuta crocuta, in Majete Wildlife Reserve, Malawi
Spotted hyena, Crocuta crocuta, home range size in the Majete Wildlife Reserve (MWR), Malawi, was determined using data collected from camera traps. Cameras were placed throughout the reserve atExpand

Molecular systematics of the Hyaenidae: relationships of a relictual lineage resolved by a molecular supermatrix.
TLDR
The pattern of relationships among the three bone-cracking hyaenids is incongruent with recent cladistic assessments based on morphology and suggests the need to reevaluate some of the morphological characters that have been traditionally used to evaluate relationships among hyenas. Expand
Carnivore Group Living: Comparative Trends
TLDR
This chapter briefly review selected hypotheses for the evolution and maintenance of grouping in carnivores, focusing on those that are broadly applicable across the order and are testable from the available comparative data. Expand
Hyaenas: Status Survey And Conservation Action Plan
TLDR
This action plan sets out to address some of the problems facing this species of animal, particularly the issue of public perception and awareness, and provides guidelines to rectify this situation. Expand
Feeding and social behaviour of the striped hyaena (Hyaena vulgaris Desmarest)
TLDR
Striped hyaenas are more omnivorous than spotted ones, scavenging a great deal and eating insects, fruits and small vertebrate prey, but the diets of the two species have several food species in common, and there is competition in the relatively small area where the geographical ranges and habitats of theTwo hyAenas overlap.

Mechanisms of maternal rank ‘inheritance’ in the spotted hyaena, Crocuta crocuta
TLDR
Young hyaenas and primates appear to 'inherit' their mothers' ranks by strikingly similar mechanisms, although Hyaena rank acquisition did not appear to be directly affected by genetic heritability. Expand
Social intelligence in the spotted hyena (Crocuta crocuta)
TLDR
Spotted hyenas appear to rely more intensively than primates on social facilitation and simple rules of thumb in social decision making, and the gross anatomy of the brain in spotted Hyenas might resemble that in primates with respect to expansion of frontal cortex, presumed to be involved in the mediation of social behaviour.

Sex Differences in Territorial Behavior Exhibited by the Spotted Hyena (Hyaenidae, Crocuta crocuta)
Spotted hyenas (Crocuta crocuta) are gregarious carnivores that defend group territories against encroachment by neighboring conspecifics. Here we monitored the behavior of members of one clan ofExpand
Reproductive skew among males in a female-dominated mammalian society
TLDR
The data support a ‘‘limited control’’ model of reproductive skew in this species, in which female choice may play a more important role in limiting control by dominant males than do power struggles among males. Expand
Aardwolf mating system: Overt cuckoldry in an apparently monogamous mammal
TLDR
The aardwo/f is an apparently monogamous mammal that practices regular promiscuous matings, as a result of which some males would appear to be cuckolding their neighbours, and the conjlicting interests and the reproductive consequences are considered. Expand
Sexual conflicts in spotted hyenas: male and female mating tactics and their reproductive outcome with respect to age, social status and tenure
TLDR
Female mate choice matched observed patterns of affiliative male–female behaviour, indicating that affiliative behaviour is a successful male mating tactic, and was consistent with the idea that male tenure may serve as an index of male quality, although male fertility may decline with extreme old age.
