Miniaturization leads to considerable reorganization of structures in insects, affecting almost
all organs and tissues. In the smallest insects, comparable in size to unicellular organisms …

Miniaturized species have evolved in many animal lineages, including insects and
vertebrates. Consequently, their nervous systems are constrained to fit within tiny volumes …

Human brain size nearly quadrupled in the six million years since Homo last shared a
common ancestor with chimpanzees, but human brains are thought to have decreased in …

Insects are the most ecologically important multicellular heterotrophs in terrestrial systems.
They play critical roles in ecological food webs, remain devastating agricultural and medical …

Ultrasociality refers to the social organization of a few species, including humans and some
social insects, having a complex division of labor, city-states, and an almost exclusive …

Trait databases have become important resources for large-scale comparative studies in
ecology and evolution. Here we introduce the AnimalTraits database, a curated database of …

The extraordinary success of social insects is partially based on division of labour, ie
individuals exclusively or preferentially perform specific tasks. Task preference may …

Larger animals studied during ontogeny, across populations, or across species, usually
have lower mass-specific metabolic rates than smaller animals (hypometric scaling). This …

Many comparative neurobiological studies seek to connect sensory or behavioural attributes
across taxa with differences in their brain composition. Recent studies in vertebrates suggest …

An organism's morphology plays a crucial role in its interactions with its environment.
Therefore, comparative anatomical analysis is a critical basis to understanding the ecology …
