Phosphorus has been identified as an important determinant of nutrition-related biological
variation. The macronutrients protein (P) and carbohydrates (C), both alone and …

Gryllus field and wood crickets of the United States, mostly west of the Mississippi River, are
reviewed and revised. We validate the following 18 Gryllus cricket names: G. armatus, G …

Highlights•Calling in crickets involves repeated mechanical wing movements
(performance).•Individuals differed in calling vigour and in changes in vigour with …

The terminal investment hypothesis proposes that decreased expectation of future
reproduction (eg, arising from a threat to survival) should precipitate increased investment in …

Communication via substrate-borne vibrations is the most widespread form of acoustic
communication in arthropods. However, remarkably little is known about physiological …

The evolution of mating signals is closely linked to sexual selection. Acoustic ornaments are
often used as secondary sexual traits that signal the quality of the signaller. Here we show …

Acoustic communication is one of the most well-known behavioural traits of the Orthoptera.
Orthopteran insects and the sounds they produce are both extremely diverse, and species …

The age of potential mates has been proposed to be an important target for mate choice by
females. Alternative hypotheses predict preferences in either direction. Females might be …

Aging evolved because the strength of natural selection declines over the lifetime of most
organisms. Weak natural selection late in life allows the accumulation of deleterious …

Phenotypic plasticity can be adaptive when phenotypes are closely matched to changes in
the environment. In crickets, rhythmic fluctuations in the biotic and abiotic environment …
