We determined the size characteristics of foragers of the leaf-cutting ant Atta sexdens in a mature eucalyptus forest in Campos dos Goytacazes, Rio de Janeiro State, Brazil, at daytime (7: 30 to 10: 00 hr) and nighttime (19: 00 to 23: 00 hr).

A comprehensive, integrative study approach combining morphology, population genetics, phylogenetics and biogeography revealed that the Acromyrmex octospinosus species complex consists of two species: A. octospinosus and its social parasite A. insinuator.

The Evolutionary Innovation of Nutritional Symbioses in Leaf-Cutter Ants
Fungus-growing ants gain access to nutrients stored in plant biomass through their association with a mutualistic fungus they grow for food. This 50 million-year-old obligate mutualism likely facilitated some of these species becoming dominant ...

Texas leaf cutter ant (Atta texana) populations have expanded northward and their obligate symbiotic fungus has increased cold tolerance. The ants have exquisitely temperature sensitive antennae; here, we find the antennae express a subset of six transient receptor potential (TRP) channels, including HsTRPA.

Distressed Camponotus modoc carpenter ants emit alarm pheromone and produce vibratory alarm signals. Presented as a monomodal signal, the pheromone attracts nestmates, whereas vibratory signals cause nestmates to “freeze” or to run fast. Sensing a bimodal signal complex, nestmates are less attracted to pheromone but stay “frozen” longer which seems ...

Rare plant and vertebrate species have been documented to contribute disproportionately to the total morphological structure of species assemblages. These species often possess morphologically extreme traits and occupy the boundaries of morphological space.

DNA methylase 1 influences temperature responses and development in the invasive pest Tuta absoluta
Dnmt1 regulates the adaptability of tomato leaf miner to temperature. TaDnmt1 RNAi impacts the larval growth and development, resulting in a significant increase (57%) in larval mortality and decrease in pupation (49.3%) and pluming (50.9%). The rapid geographic expansion of Tuta absoluta infestation is closely associated with TaDnmt1‐mediated ...
