Social Carrying and Defensive Behavior During Colony Emigration in the Leaf-cutting Ant Atta sexdens
Sociobiology, 2017 In this work, we describe for the first time and under laboratory conditions, the behaviors related to social carrying and defensive strategies during colony emigration in the leaf-cutting ant Atta sexdens.

Trace Element Patterns in Juvenile Wild Chimpanzee Dentitions
Archaeometry, EarlyView.ABSTRACT Trace elements are used to infer mammalian early‐life diets, environmental toxins, dispersal patterns, stress histories, and weaning ages. Here, we employ laser ablation‐inductively coupled plasma‐mass spectrometry (LA‐ICP‐MS) to reveal elemental patterns in our closest living relatives, chimpanzees.

Atta texana, Texas Leaf-cutting Ant, on Typic Quartzipsamments: Ecological Considerations [PDF]
, 1996 Pine plantations on Typic Quartzipsamments in East Texas are difficult to establish. Forest management options following clearcutting are limited. An 8-year regeneration study of the growth and survival of loblolly, Pinus taeda, L. shortleaf, P. echinata

Acta Zoologica, EarlyView.ABSTRACT This study investigated shape variations and morphological integration between the components of crusher and cutter claws in two species of swimming crabs, Callinectes danae and Callinectes ornatus. The propodi and dactyli of the claws were analysed in males and females of both species, using geometric morphometric techniques to identify ...

THE ECOLOGY OF MUTUALISM [PDF]
, 1982 Elementary ecology texts tell us that organisms interact in three fundamen tal ways, generally given the names competition, predation, and mutualism. The third member has gotten short shrift (264), and even its name is not generally agreed on.

Two castes sizes of leafcutter ants in task partitioning in foraging activity
Ciência Rural: Task partitioning in eusocial animals is most likely an evolutionary adaptation that optimizes the efficiency of the colony to grow and reproduce. It was investigated indirect task partitioning in two castes sizes; this involves task partitioning in ...

Conservation Science and Practice, EarlyView.Yellow crazy ants (Anoplolepis gracilipes; YCA) are widespread invaders of islands across the Pacific and Indian Oceans. We investigated the ecological preferences and impacts of this species on a Polynesian atoll. We show that even at low abundances, this species can have important impacts on the fauna, including seabirds, and require management ...
