Pre-reproductive parental enriching experiences influence progeny’s developmental trajectories [PDF]
, 2018 While the positive effects of environmental enrichment (EE) applied after weaning, in adulthood, during aging, or even in the presence of brain damage have been widely described, the transgenerational effects of pre-reproductive EE have been less ...

Existence of periodic solutions for the periodically forced SIR model [PDF]
, 2013 We prove that the seasonally-forced SIR model with a T-periodic forcing has a periodic solution with period T whenever the basic reproductive number R0>1. The proof uses the Leray-Schauder degree theory.

Intersexual conflict influences female reproductive success in a female-dispersing primate [PDF]
, 2019 In group-living mammals, individual efforts to maximize reproductive success result in conflicts and compromises between the sexes. Females utilize counterstrategies to minimize the costs of sexual coercion by males, but few studies have examined the ...
