Abstract Ants (Hymenoptera: Formicidae) are a conspicuous group of ectotherms whose
behavior, distribution, physiology, and fitness are regulated by temperature. Consequently …

Body size is a key life-history trait influencing all aspects of an organism's biology. Ants
provide an interesting model for examining body-size variation because of the high degree …

Abstract The Thermal Adaptation Hypothesis posits that the warmer, aseasonal tropics
generates populations with higher and narrower thermal limits. It has largely been tested …

Aunque los orígenes de las hormigas (cuándo, dónde y cómo) sean misterios que nunca
podremos resolver, lo cierto es que hace unos 100 millones de años ya existían hormigas …

1. The size–grain hypothesis maintains that as terrestrial walking organisms decrease in
size, their environment becomes less planar and more rugose. The benefits of long legs …

1. In Mediterranean ant communities, a close relationship has been found between activity
rhythm in the period of maximum activity and position in the dominance hierarchy …

In recent years the focus in ecology has shifted from species to a greater emphasis on
functional traits. In tandem with this shift, a number of trait databases have been developed …

Species richness describes the number of species of a given taxon in a given time and
space. The energy limitation hypothesis links the species richness of consumer taxa to net …

The tropical forest canopy and litter differ in physical structure, resource availability, and
abiotic conditions. We used standardized bait experiments in the canopy and litter of four …

We present a new approach to determine the number and composition of guilds, using the
hyperdiverse leaf‐litter ant fauna as a model, based on appropriate morphological variables …
