Access to Resources Shapes Sex Differences Between Caring Parents
Autor: Tom Ratz, Katerina Kremi, Lyndon Leissle, Jon Richardson, Per T. Smiseth
Publikováno v: Frontiers in Ecology and Evolution, Vol 9 (2021)
In species where both parents cooperate to care for their joint offspring, one sex often provides more care than the other. The magnitude of such sex differences often varies both between and within species and may depend on environmental conditions,

Waist-to-height ratio is more predictive of years of life lost than body mass index.
Autor: Margaret Ashwell, Les Mayhew, Jon Richardson, Ben Rickayzen
Publikováno v: PLoS ONE, Vol 9, Iss 9, p e103483 (2014)
Our aim was to compare the effect of central obesity (measured by waist-to-height ratio, WHtR) and total obesity (measured by body mass index, BMI) on life expectancy expressed as years of life lost (YLL), using data on British adults.A Cox proportio

Unlike a virgin: a meta-analytical review of female mating status in studies of female mate choice
Autor: Jon Richardson, Marlene Zuk
Publikováno v: Behavioral Ecology. 34:165-182
Studies of female mate choice commonly use virgin females as test subjects, either to control for the effects of mating or because virgin females are presumed to be more responsive to mating cues. Theory predicts that virgin females will be less choo

Rethinking same-sex sexual behaviour: male field crickets have broad mating filters
Autor: Jon Richardson, Marlene Zuk
Publikováno v: Proceedings of the Royal Society B: Biological Sciences. 290
Same-sex sexual behaviour (SSB) occurs in many animals and is often treated as an anomaly requiring special explanation. One common explanation for SSB is mistaken identity. However, animals make similar ‘mistakes’ in other contexts—such as att

Increased allocation to reproduction reduces future competitive ability in a burying beetle
Autor: Jon Richardson, Josh Stephens, Per T. Smiseth
Publikováno v: Richardson, J, Stephens, J & Smiseth, P T 2020, ' Increased allocation to reproduction reduces future competitive ability in a burying beetle ', Journal of Animal Ecology . https://doi.org/10.1111/1365-2656.13242
1. The existence of a trade-off between current and future reproduction is a fundamental prediction of life-history theory. Support for this prediction comes from brood size manipulations, showing that caring for enlarged broods often reduces the par

Maternity uncertainty in cobreeding beetles: females lay more and larger eggs and provide less care
Autor: Jon Richardson, Per T. Smiseth
Publikováno v: Richardson, J & Smiseth, P T 2020, ' Maternity uncertainty in cobreeding beetles : Females lay more and larger eggs and provide less care ', Behavioral Ecology . https://doi.org/10.1093/beheco/araa006
Cobreeding, which occurs when multiple females breed together, is likely to be associated with uncertainty over maternity of offspring in a joint brood, preventing females from directing resources towards their own offspring. Cobreeding females may r

Adjustment of egg laying by both hosts and intraspecific brood parasites in a beetle
Autor: Sarah Dobson, Per T. Smiseth, Jon Richardson, Lucy E. Ford
Publikováno v: Richardson, J, Dobson, S, Ford, L E & Smiseth, P T 2021, ' Adjustment of egg laying by both hosts and intraspecific brood parasites in a beetle ', Ethology . https://doi.org/10.1111/eth.13209
Brood parasites lay their eggs in the nests of other females, thereby shifting the costs of offspring care onto others. Given that care is costly, potential hosts should evolve mechanisms to avoid brood parasitism. Meanwhile, brood parasites should e
