The diversity of mammalian mating systems is primarily shaped by sex-specific reproductive strategies. In the present study, we explored determinants and consequences of a unique mating system exhibited by fossas (Cryptoprocta ferox), the largest Malagasy carnivore, where females mate polyandrously on traditional mating trees, and males exhibit intrasexual size dimorphism. Males face both contest and scramble competition, and inter-sexual size dimorphism can be pronounced, but its magnitude… Expand

Mate choice screening in captive solitary carnivores: The role of male behavior and cues on mate preference and paternity in females of a model species, American mink (Neovison vison).
TLDR
The results suggest that even though there was a preference difference in scent stimulus trials from potential mates this preference was not predictive of eventual mate preference or paternity, and supports that mate preference and mate choice are complex matters influenced by multiple cues and signals.

Sex Role Reversal and High Frequency of Social Polyandry in the Pheasant-Tailed Jacana (Hydrophasianus chirurgus)
In a few species, males invest more than females in parental care while the females invest in mating competition and producing multiple broods for several mates. Species in the family Jacanidae areExpand
Gregarious sexual segregation: the unusual social organization of the Malagasy narrow-striped mongoose (Mungotictis decemlineata)
TLDR
This study presents new detailed results on the sex-specific social organization of a previously unstudied endemic Malagasy carnivore, the narrow-striped mongoose, and evaluates the results in comparison to the closest related taxonomic group, the mongooses, in which long-term studies have contributed substantially to the recent development of theories. Expand
Evolutionary dynamics of sexual size dimorphism in non-volant mammals following their independent colonization of Madagascar
TLDR
It is concluded that neither the eco-evo-devo hypothesis, founder effects, the island rule nor sexual selection theory alone can provide a compelling explanation for the observed patterns of SSD in Malagasy mammals. Expand
Studying the Effects of Predatory Presence and Enrichment on Cryptoprocta ferox Behavior
The Central Florida Zoo and Botanical Gardens houses two fossa (Cryptoprocta ferox), a male and a female. C. ferox is an endangered species of Malagasy mongoose from the island of Madagascar. InExpand
Human Impact on Space Use, Activity Patterns, and Prey Abundance of Madagascar's Largest Natural Predator, Cryptoprocta ferox
TLDR
A comprehensive assessment on habitat pressures experienced by the fosa was conducted in Ankarafantsika National Park, a dry deciduous forest in the northwest region of the country, and one of the two places where viable fosa populations still exist. Expand
Teasing Apart Impacts of Human Activity and Regional Drought on Madagascar’s Large Vertebrate Fauna: Insights From New Excavations at Tsimanampesotse and Antsirafaly
Madagascar experienced a major faunal turnover near the end of the first millenium CE that particularly affected terrestrial, large-bodied vertebrate species. Teasing apart the relative impacts ofExpand
Who Ate the Subfossil Lemurs? A Taphonomic and Community Study of Raptor, Crocodylian and Carnivoran Predation of the Extinct Quaternary Lemurs of Madagascar.
TLDR
It is shown here how to identify the wood of several species common to the Northern Lights using a variety of techniques, including X-ray diffraction, averaging out to about 3.5mm for each type of fruit. Expand

Sex in the dark: determinants and consequences of mixed male mating tactics in Microcebus murinus, a small solitary nocturnal primate
TLDR
It is found that, with a given relatively low overall monopolization potential, successful male mouse lemurs roamed extensively in search of mates, had superior finding ability and mated as early as possible, however, contest competition was important too, as temporary monopolization was also possible. Expand
A novel mating system in a solitary carnivore: the fossa
TLDR
Fossas are at low population density and do not use a den regularly; it is suggested that both these factors impede individuals from locating a mate and increases the number of mates available to a female while ensuring a low risk of sexual harassment. Expand
Female reproductive strategies in orangutans, evidence for female choice and counterstrategies to infanticide in a species with frequent sexual coercion
TLDR
The results support the hypothesis that, together with concealed ovulation, facultative association is a mechanism of female choice in a species in which females can rarely avoid coercive mating attempts and female resistance, which reduced copulation time, may provide an additional mechanism for mate selection. Expand
The large-male advantage in brown antechinuses: female choice, male dominance, and delayed male death
TLDR
The results suggest that the other three mechanisms of sexual selection tested account for the large-male advantage: large males competed more successfully for mates, so were socially dominant; females rejected subordinates; and dominant males survived for longer after their first mating. 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. Expand
Overt and covert competition in a promiscuous mammal: the importance of weaponry and testes size to male reproductive success
TLDR
The Soay sheep mating system is characterized by male contests for mating opportunities and high female promiscuity and it is found that greater horn length, body size and good condition each independently influence a male' ability to monopolize receptive females. Expand
A Comparison of Female Mating Strategies in Pan troglodytes and Pongo spp.
TLDR
Analysis of mating patterns in orangutans and chimpanzees concludes that both genera pursue tactics for paternity confusion by mating with multiple males and by mating cooperatively or even proceptively with nonpreferred partners when conception is unlikely. Expand
Polyandry occurs because females initially trade sex for protection
TLDR
In the fiddler crab Uca mjoebergi, females mate multiply using two distinct mating tactics: surface and burrow mating, and it is found that females gained a different benefit from each type of mating. Expand
The costs of mating and mate choice in water striders
TLDR
Mating females are at twice the risk of predation than are single females, and some components of mating behaviour in males also appear to increase predation risk. Expand
Polyandry as a mediator of sexual selection before and after mating
  • C. Kvarnemo, L. Simmons
  • Biology, Medicine

TLDR
Polyandry can reduce a male's ability to monopolize females, and thus weaken male focused sexual selection, and estimates of sexual selection intensity rely heavily on measures of male mating success, but polyandry now raises serious questions over the validity of such approaches. Expand
