Sex ‐specific catch‐up growth in the Texas field cricket, Gryllus texensis
In this study, we investigated compensatory/catch‐up growth and its sex‐specific costs in a field cricket. After a 4‐week period of poor‐quality food, treatment crickets were switched to a good‐quality diet until maturity. We predicted that males and females would respond to this diet change differently, as the importance of large body size differs between sexes. Contrary to our prediction, we found that neither male nor female crickets increased their growth rates after realimentation compared with controls. Despite a lack of compensatory growth, both sexes attained the same average body size, mass, and conditio...

The effect of distastefulness and conspicuous coloration on the post ‐attack rejection behaviour of predators and survival of prey
Aposematic insects use bright colours and/or distinct markings to advertise their toxins to potential predators. When toxins are bitter‐tasting and detectable upon attack, birds are able to use taste when making decisions about whether or not to eat defended prey. Taste‐rejection behaviour, when birds taste but do not ingest a prey item, is often assumed to increase the survival of defended prey, yet few empirical studies have investigated the post‐attack survival rates of live defended insects. We used naïve domestic chicks (Gallus gallus domesticus) foraging on live waxmoth larvae (Galleria mellonella) in a labora...

Phylogeography and population structure of two Brachistosternus species (Scorpiones: Bothriuridae) from the Chilean coastal desert – the perils of coastal living
Coastal deserts are geologically dynamic areas of the Earth, affected by historical changes in sea levels and in some cases also by fault‐line tectonic activity. An example of such a dynamic area is the Chilean coastal desert of the Antofagasta and Atacama regions, which harbours many endemic species, such as the bothriurid scorpion species Brachistosternus paposo and Brachistosternus roigalsinai. In this work, we carry out phylogeographic and population genetic analyses on these scorpions, using two mitochondrial (COI and cyt b) and two nuclear (Actin 5C and wingless) markers to identify species and population structuri...
