Dispersal has consequences not only for individual fitness, but also population dynamics, genetics and species distribution. Social Hymenoptera show two contrasting colony reproductive strategies, dependent independent foundation modes, these are often associated to the structures derived from inter intra-population gene flow processes conditioned by alternative dispersal strategies. Here we employ microsatellite mitochondrial markers investigate social genetic structure patterns in ant...
AbstractAbstractAnts are important consumers in most terrestrial ecosystems. They show a great diversity of diets and foraging strategies. Here, we analyzed how circannual variation resource use by the Mediterranean species Aphaenogaster senilis is related to colony life cycle availability. In southwestern Spain, this active almost year-round, but intensity decreases 10-fold between March November, following larval production. summer, ants refrain from at midday avoid high temperatures. We...
Nycthemeral rhythm is an important biological trait that allows animals to escape predation and competition and, conversely, coincide with mutualists. Although laboratory studies have shown the depends on both endogenous factors cyclic environmental cues, latter often poorly understood, particularly in wild. Because insects are mostly ectothermal organisms, their activity thought depend directly ground temperature. In Mediterranean habitats, Cataglyphis ants well known for unusual...
Gene flow is the main force opposing divergent selection, and its effects are greater in populations close proximity. Thus, complete reproductive isolation between parapatric not expected, particularly absence of ecological adaptation sharp environmental differences. Here, we explore biogeographical patterns an endemic ant species, Cataglyphis floricola, for which two colour morphs (black bicolour) coexist parapatry throughout continuous sandy habitat southern Spain. Discriminant analyses...
1. In many ant species, caste differentiation stems from trophic differences at the larval stage. Adult workers that feed larvae have great control over allocation of colony resources to growth (production workers) versus reproduction queens). However, fate may also be constrained very early on through direct genetic effects or non‐genetic maternal effects. 2. Here, we combined isotopic and analyses study developmental origin queens in a desert‐dwelling ant, C ataglyphis tartessica (Amor...
Abstract Aim Predictions of future species distributions rest on the assumption that climatic conditions in current range reflect fundamental niche requirements. So far, it remains unclear to what extent this is true. We tested if three important factors determining niche—ecophysiology, morphology and evolutionary history—can predict realized niche, using thermal specialist ants. They are suitable model organisms because their body temperature, metabolism fitness closely tied habitat...
In insects, body colour may serve as a thermoregulatory mechanism: higher levels of melanin result in pronounced heat absorption. Consequently, dark would not be appropriate very hot niches due to the overheating risks that it entail.Ants genera Ocymyrmex and Cataglyphis are characterized by foraging thermal conditions tolerated any other species ants. However, both have black red or morphs. this work we looked for environmental factors associated these colouration differences well effect...
