Diverse invertebrate species have been used for studies of learning and comparative
cognition. Although we have gained invaluable information from this, in this study we argue …

The biogenic amine octopamine and its biological precursor tyramine are thought to be the
invertebrate functional homologues of the vertebrate adrenergic transmitters. Octopamine …

Polyphenism is the phenomenon where two or more distinct phenotypes are produced by
the same genotype. Examples of polyphenism provide some of the most compelling systems …

Abstract Locusts are grasshoppers (Orthoptera: Acrididae) that are characterised by their
capacity for extreme population density-dependent polyphenism, transforming between a …

Over the past decade, technological advances in experimental and animal tracking
techniques have motivated a renewed theoretical interest in animal collective motion and, in …

Locust density-dependent phase polyphenism presents a quintessential example of
environmentally induced plasticity. Almost a century of research has yielded ample …

Background The desert locust (Schistocerca gregaria) displays a fascinating type of
phenotypic plasticity, designated as 'phase polyphenism'. Depending on environmental …

The mechanisms that integrate genetic and environmental information to coordinate the
expression of complex phenotypes are little understood. We investigated the role of two …

Collective phenomena are studied in a range of contexts—from controlling locust plagues to
efficiently evacuating stadiums—but the central question remains: how can a large number …

Locusts are among the most dangerous agricultural pests. They are a group of short horned
grasshoppers belonging to Acrididae family and are hemimetabolous insects. This group of …
