Worker caste determination in the army ant Eciton burchellii.
Elaborate division of labour has contributed significantly to the ecological success of social insects. Division of labour is achieved either by behavioural task specialization or by morphological specialization of colony members. In physical caste systems, the diet and rearing environment of developing larvae is known to determine the phenotype of adult individuals, but recent studies have sho...
متن کاملDispersal and population structure of a New World predator, the army ant Eciton burchellii.
The army ant Eciton burchellii is probably the most important arthropod predator in the Neotropics, and many animal species depend upon it. Sex-biased dispersal with winged males and permanently wingless queens may render this species especially sensitive to habitat fragmentation and natural barriers, which might have severe impacts on population structure and lead to population decline. Using ...
متن کاملOptimal construction of army ant living bridges.
Integrating the costs and benefits of collective behaviors is a fundamental challenge to understanding the evolution of group living. These costs and benefits can rarely be quantified simultaneously due to the complexity of the interactions within the group, or even compared to each other because of the absence of common metrics between them. The construction of 'living bridges' by New World ar...
متن کاملBehavioral Biology and Observations of a Statary Eciton Burchelli Army Ant Colony at La Selva Biological Station
Little is known of the ecology and behavioral biology of Eciton burchelli army ants at La Selva biological station, Costa Rica. A statary colony of E. burchelli was followed for seven days in July (wet season). Colony movements were recorded and entered into the La Selva GIS system. Angle of daily raids, velocity of foraging front and distance foraged were recorded. Estimates were made of numbe...
متن کاملMyrmecophiles
How diverse are myrmecophiles? In 1894, Erich Wasmann, an Austrian Jesuit priest and one of the pioneering students of myrmecophiles, documented 1,177 ant guests, and the list has grown at an astonishing rate ever since. Myrmecophily has evolved independently in a large number of taxonomic groups, including flies (Figure 1A), beetles (Figure 1B and C), crickets (Figure 1D), butterflies (Figure ...
