Insect bioindicators have been used the world over, but they have seldom been used to evaluate revegetation efforts on previously pastoral land. The present study aimed to evaluate the health and biodiversity of a 3-year-old revegetated plot of previously pastoral land in Australia by comparing it to a mature forest, using ants and flying insects as bioindicators. Using ant baits and a nocturna...

Morphological evolution in ants has been traditionally thought as being strongly influenced by selection for colony ergonomic efficiency. Although many studies have focused on the evolution of social characteristics in ants, little is known about the evolution of worker morphology at a macroevolutionary scale. In this study, we investigate the tempo and mode of the evolution of worker morpholog...

Topical application of juvenile hormone analog induces soldier development in the ant Pheidole bicarinata. Soldier induction takes place if the juvenile hormone analog is present during a period of sensitivity that occurs during the last larval instar. Control of worker dimorphism seems to be accomplished through control of timing of metamorphosis. The smallest size at which metamorphosis can b...

Background: This study focused on evaluating the diversity and richness of edaphic macrofauna in eight banana farms western zone Nicaragua. Methods: The sampling design was random descriptive, it divided into two phases, first collection sample, second classification, coding, storage extracted populations. Subsequently, indices spe...

We investigated whether the physical castes of the dimorphic ant Pheidole pallidula (Nylander) (Hymenoptera: Formicidae), are involved in determining within-nest activities and how their social investment in everyday tasks is influenced by large changes in the colony's caste ratio. Although the large-headed majors are morphologically distinct from minors, they are similar in size, exhibit simil...

The West-Palearctic region is a diversity hotspot for the ant genus Aphaenogaster . Species in this are characterized by high morphological variation, which has led to their subdivisioninto different infrageneric groups. very first classification three subgenera, dated 1915, was gradually replaced eight species-groups. To probe evolutionary consistency of these species-groups, we sequenced 46 s...
