Social monogamy, considered rare in mammals, has been described in two species of beaver, the Eurasion beaver (Castor fiber), and the North American beaver (Castor Canadensis). Social monogamy, however, does not necessarily imply genetic monogamy. For example, in group living mammals, females may engage in extra-pair copulations as a result of increased female mate choice opportunities. Recently, following genetic analysis, a wide range of genetic relationships among colony members have been… Expand

Genetic monogamy and mate choice in a pair-living primate
It is suggested that even opportunistic dispersal, as long as it is not constrained, can generate sufficient genetic diversity to prevent inbreeding, which can render active inbreeding avoidance via mate choice and extra-pair copulations less necessary, helping to maintain genetic monogamy. Expand
Extra-territorial movements differ between territory holders and subordinates in a large, monogamous rodent
GPS-tagged 54 Eurasian beavers during the non-mating season and investigated forays in territory-holding breeders (dominants) and non-breeding family members, suggesting that forays are energetically costly. Expand
Landscape structure and population density affect intraspecific aggression in beavers
It is emphasized that population density can affect intraspecific aggression depending on landscape structure, which might have important consequences for local patterns of dispersal, mate change, and territory occupancy, all of which can affect population dynamics. Expand
Timing of reproduction and paternal cares in the crested porcupine
This work reports the first data on reproductive biology and paternal behaviour of free-living crested porcupines in Europe, and confirms that alternation of cub guarding in den occurs in the first two months of life, when quills are still soft and relatively short, thus making cubs an easy prey for small and mesocarnivores.

Recolonizing lost habitat—how European beavers (Castor fiber) return to south-western Germany
For the last decades, the European beaver (Castor fiber) has been recolonizing its original habitats. Reintroductions of beavers from different relict populations into southern Germany have resultedExpand
Highly Polymorphic Microsatellite Markers for the Assessment of Male Reproductive Skew and Genetic Variation in Critically Endangered Crested Macaques (Macaca nigra)
The results suggest that the Tangkoko population of crested macaques is still genetically variable despite its small size, isolation, and the species’ reproductive patterns, and gives hope that other endangered primate species living in small, isolated populations may also retain a healthy gene pool, at least in the short term. Expand
Couch potatoes do better: Delayed dispersal and territory size affect the duration of territory occupancy in a monogamous mammal
The found that individuals that established in medium‐sized territories occupied them longer as compared to individuals in small or large territories, which suggests that large territories are more costly to defend due to an increased patrolling effort and small territories might not have sufficient resources. Expand
The 7-year itch: non-adaptive mate change in the Eurasian beaver
The causes of mate change in the Eurasian beaver are investigated and it is found that mate change was not initiated by a member of the mated couple but rather by the intrusion of an incoming individual as suggested by the ‘forced divorce’ hypothesis. Expand

Why do some animals mate with one partner rather than many? Here, I investigate factors related to (i) spatial constraints (habitat limitation, mate availability), (ii) time constraints (breedingExpand
Home range use in the West Australian seahorse Hippocampus subelongatus is influenced by sex and partner’s home range but not by body size or paired status
Genetic monogamy is the rule for many species of seahorse, including the West Australian seahorse Hippocampus subelongatus. In this paper, we revisit mark-recapture and genetic data of H.Expand


Microsatellite analysis of mating and kinship in beavers (Castor canadensis)
In contrast to long-held views that beavers are genetically monogamous and colonies are typically 1st-order relatives, a wide range of relationships among colony members and multiple paternity in >50% of litters are documented. Expand
Correlates of genetic monogamy in socially monogamous mammals: insights from Azara's owl monkeys
Analysis of the relationship between paternal care and strength of the pair bond and the genetic mating system of socially monogamous mammals show that, once social monogamy has evolved, paternal care, and potentially also close bonds, may facilitate the evolution of genetic monogamy. Expand
Long-term pair bonding and genetic evidence for monogamy among urban coyotes (Canis latrans)
Despite the high food resources available and high population density, urban coyotes display no variability in their monogamous mating system, according to radiotelemetry and genetic techniques. Expand

Genetic and behavioural evidence of monogamy in a mammal, Kirk's dik–dik (;Madoqua kirkii)
Behaviour and genetic evidence of fidelity in a socially monogamous dwarf antelope, Kirk's dik–dik, is presented and it is proposed that females avoid extra–pair males because they are unable to mate with them without instigating a potentially dangerous conflict. Expand
Monogamy: Monogamy correlates, socioecological factors, and mating systems in beavers
This volume provides some fresh data about EPCs in mammals, which are less studied than birds in this respect and based on a few socially monogamous species that have been genetically screened, strict genetic monogamy appears to be much rarer in mammals. Expand
Intraspecific Variation in the Social Systems of Wild Vertebrates
Intraspecific socioecological analysis of wild vertebrates finds that the ability to predict, and possibly even influence, rapid changes in social systems may contribute substantially to conservation strategies. Expand
The Genetic Legacy of Multiple Beaver Reintroductions in Central Europe
It is shown that beavers from at least four source origins currently form admixed, genetically diverse populations that spread across the study region, and argued that admixture between different beaver source populations should be generally accepted. Expand
The degree of extra-pair paternity increases with genetic variability.
It is shown that the amount of genetic variability in a population may be an important factor influencing mating patterns, and it was found that genetic diversity was higher in the populations with a higher level of extra-pair paternity. Expand
