Mum knows best: female lizards choose warm, moist nests to produce better offspring

Shu-Ran Li, Xin Hao, Yang Wang, Bao-Jun Sun, Jun-Huai Bi, Yong-Pu Zhang, Fredric J. Janzene Wei-Guo Du In egg-laying animals, the nest sites chosen by a mother can determine the quality and survival of offspring because nest environments can profoundly affect embryonic development and hatchling traits. However, field studies identifying the long-term effects of nest-site…

Maternal egg hormones in the mating context: the effect of pair personality

Suvi Ruuskanen, Ton G.G. Groothuis, Alexander T. Baugh, Sonja V. Schaper, Bonnie de Vries, Kees van Oers Across animal taxa from insects to mammals (also humans) individuals differ consistently in their behaviour. For example, some are always shyer and some are bolder when facing new situations. The origin of so called ‘personalities’ is partly genetic,…

Nursing behaviour of neonate humpback whales

Simone K. A. Videsen, Lars Bejder, Mark Johnson and Peter T. Madsen Humpback whales belong to the group of large baleen whales that embark on long distance migrations each year between foraging and breeding grounds. These long migrations result in a short time window on breeding grounds, where pregnant females must give birth and nurse…

Predator foraging response to a resurgent dangerous prey

Aimee Tallian, Douglas W. Smith, Daniel R. Stahler, Matthew C. Metz , Rick L. Wallen, Chris Geremia, Joel Ruprecht, C. Travis Wyman, Daniel R. MacNulty ‘Prey switching’ refers to a change in the diet of a predator as the abundance of two prey species changes. Prey switching is ecologically important because it can stabilize prey…

Plant defense negates pathogen manipulation of vector behavior

Baiming Liu, Evan L. Preisser, Xiaobin Shi, Huaitong Wu, Chuanyou Li, Wen Xie, Shaoli Wang, Qingjun Wu, Youjun Zhang Many important and economically-damaging plant pathogens are transmitted by insect vectors, and pathogens have been shown to alter vector behavior in ways that promote both their uptake and transmission. In the Tomato yellow leaf curl virus…
