DOI: 10.1002/ece3.8938
Abstract: Abstract Numerous studies have examined whether the primary and/or secondary sex ratio in mammals, including humans, deviates from an equilibrium of 1:1. Although effect size in the sex ratio variation is expected to be low,… read more here.

DOI: 10.1002/etc.5581
Abstract: Screening and testing of potential endocrine‐disrupting chemicals for ecological effects are examples of risk assessment/regulatory activities that can employ adverse outcome pathways (AOPs) to establish linkages between readily measured alterations in endocrine function and whole… read more here.

DOI: 10.1016/j.aquatox.2019.105242
Abstract: Some progestins, including the widely used dydrogesterone (DDG), have been shown to cause male-biased sex ratio in teleost. However, there is a gap to fully understand the mechanisms of the sex differentiation disturbance by progestins,… read more here.

DOI: 10.1016/j.aquatox.2020.105476
Abstract: Nonsteroidal anti-inflammatory drugs (NSAIDs) are widely used pharmaceuticals to treat pain, fever and inflammation. NSAIDs are also known to have many side effects including adverse effects on reproduction in both humans and animals. As NSAIDs… read more here.

DOI: 10.1016/j.evolhumbehav.2016.10.013
Abstract: In this paper, we use a combination of evolutionary theory, ethnographic data, written sources, and archaeological evidence to develop a new explanation for the origins of Viking raiding. Our argum ... read more here.

Evidence of male-biased dispersal in eastern grey kangaroos (Macropus giganteus)

DOI: 10.1071/zo16047
Abstract: Abstract. Dispersal reduces the likelihood of inbreeding and maintains gene flow among populations. Many polygynous mammals exhibit male-biased dispersal with female philopatry. Previous observational studies of eastern grey kangaroos (Macropus giganteus) suggested female philopatry while… read more here.

DOI: 10.1093/biolre/ioac208
Abstract: Abstract Environmental stressors to which a fetus is exposed affect a range of physiological functions in postnatal offspring. We aimed to determine the in utero effect of steroid hormones on the reproductive potential of female… read more here.

Parasite–offspring competition for female resources can explain male-biased parasitism in plants

DOI: 10.1098/rsbl.2018.0761
Abstract: Male-biased susceptibility to parasites is common in dioecious plants. However, why males have higher parasite loads than females is unclear. Unlike males, females must subsidize post-fertilization costs of reproduction (e.g. seed and fruit development). As… read more here.
