Abstract Published records of twinning and superfoetation in monotocous wild mammals are rare. Flying-foxes (Pteropodidae, Megachiroptera) occasionally produce twin offspring, fraternal twins, as well as superfoetation twins. Superfoetation occurs where a foetus is conceived when there is a foetus already developing. The resultant twins may be months apart in developmental stages so that one twin is usually born prematurely. Here, we review the current literature available on twinning and… 

High frequency of multiple paternity in Eastern red bats, Lasiurus borealis, based on microsatellite analysis.

High levels of multiple paternity have the potential to impact interpretations of genetic estimates of effective population size in this species and might be an adaptive strategy to allow for increased genetic variation and large litter size, which would be beneficial to a species threatened by population declines from wind turbines.

Hierarchical polygyny in multiparous lesser flat‐headed bats

It was found that males captured roosted with females typically sired more offspring overall than did other males and showed a greater tendency to monopolize paternity within both litters and roosting groups, and polygyny also operated within matrilineal kin, suggesting a system that might promote social cohesiveness.

Evolution of litter size in bats and its influence on longevity and roosting ecology

It is suggested that the high resource allocation to reproduction in polytocous bats limited their lifespan and the absence of a relationship between polytocy and group size indicates that the benefits of cooperative breeding surpass the costs of intrasexual competition in bats.

Last Glacial Maximum habitat change and its effects on the grey-headed flying fox (Pteropus poliocephalus Temminck 1825)

The molecular evidence for population change into a palaeoenvironmental context is placed to gauge the antiquity of any such change and assess its implications for understanding long-term flying-fox responses to contemporary habitat fragmentation and habitat change.

Reproductive delays in mammals: an unexplored avenue for post‐copulatory sexual selection

    Biological reviews of the Cambridge Philosophical Society
  • 2014
The potential for reproductive delays to facilitate post‐copulatory sexual selection is investigated, avenues for research that may further the knowledge of sexual selection are suggested and a general review of reproductive delays in mammals is provided.

Are migratory behaviours of bats socially transmitted?

The data suggest that hoary bats do not socially transmit migration routes and behaviours among close kin, similar to other long-lived animals with extended parental care.

Does delayed fertilization facilitate sperm competition in bats?

It is concluded that, once they evolve, reproductive delays may facilitate sperm competition, and that species with delays had significantly larger testes than species without them.

Taking flight: An ecological, evolutionary and genomic perspective on bat telomeres

The current knowledge on bat telomeres, telomerase expression, and how these relate to ecology, longevity and life‐history strategies are detailed, including how new high quality, chromosome‐level genome assemblies can enable us to uncover the molecular mechanisms governing telomere dynamics.

Devil women

The Tasmanian devil, an iconic carnivorous marsupial, is at risk of extinction due to a contagious cancer called devil facial tumour disease. Saving any species from extinction requires strong



Behaviour of the Black Flying Fox Pteropus alecto: 2. Territoriality and Courtship

Females actively resisted courtship approaches by males, forcing males to display a continuous determination to mate over time where determination can be considered an indicator of ‘fitness’.


The timing of reproduction, growth rates and age at maturity of the black flying-fox, Pteropus alecto, is reviewed, indicating that males mature at an age greater than females due to their slower growth rate, a phenomenon known from other megachiropteran species.

Behaviour of the Black Flying Fox Pteropus alecto: 1. An Ethogram of Behaviour, and Preliminary Characterisation of Mother-Infant Interactions

The black flying fox Pteropus alecto is one of four species of flying fox found on the Australian mainland. Little information exists about the specific behaviour of this species, and no framework

Plasticity of the circannual oscillator resolves confusion from previous contrasts betweencircannual rhythms and environmentally cued patterns, but the oscillator may be 'set' in utero in some tropical species.

Isolation and characterisation of polymorphic microsatellite loci in the vulnerable spectacled flying fox, Pteropus conspicillatus

Six microsatellite loci isolated for Pteropus rodricensis were tested against individuals of P. conspicillatus with all loci amplifying reliably and will be used to investigate population genetic structure in the vulnerable spectacled flying fox.

Biology and management of the Grey-headed Flying-fox, Pteropus poliocephalus

Collaborative management by major stakeholders (= cost-bearers) would facilitate both the development of cost-effective and benign methods for excluding flocks from inappropriate areas, and monitoring of population status.

Seasonal movements of grey-headed flying-foxes, Pteropus poliocephalus (Chiroptera : pteropodidae), from two maternity camps in Northern New South Wales

Seasonal movements of 22 Pteropus poliocephalus, from two maternity camps in north-eastern New South Wales, were monitored from January to June 1989 using radiotelemetry. The animals moved

Movements of Australian flying foxes (Pteropodidae: Megachiroptera).

Evidence is presented to show that the coastal species Pteropus poliocephalus and P. gouldi congregate in large camps from early until late summer and that the inland species P. scapulatus forms large camps in early summer but the young are born in autumn when the population is dispersed.
