3D reconstruction for an insect provides new internal structures at nanometer resolution, and the reconstructed feeding insect reveals unexpected contraction of stylet protractors and suggested a novel phloem sap-sucking model.
CenH3, the defining component of centromeres in almost all eukaryotes, was independently lost in four insect lineages that transitioned from monocentricity to holocentricity.
The discovery of the earliest direct evidence of brood care in insects demonstrates a remarkably conserved egg-brooding reproductive strategy within scale insects in stasis for nearly 100 million years.
To leverage the tools, resources and knowledge that exist for C. elegans so that we can study ecology, evolution and other aspects of biology, we need to understand the natural history of this important model organism.
Evidence suggests that the oskar gene, a critical germ line determinant in insects, was formed by fusion of bacterial and eukaryotic sequences at least 450 million years ago.
A fatty acyl reductase gene family expansion in the Hymenoptera crown group led to recruitment of novel pheromone-biosynthetic enzymes and is linked to evolution of pheromone marking behavior.
Rarity metrics reveal pervasive negative impacts of agricultural land use on soil invertebrate communities, whereas widely-used richness and diversity metrics underestimate the magnitude of these impacts.
