Unlike any other group of animals, all ant species are social: individual ants share the food they gather with their nestmates and as a consequence must repeatedly leave nest to find then return home it. These back-and-forth foraging trips have been studied for about century much our growing understanding strategies underlying animal navigation has come from these studies. One important strategy that use keep track where on trip is 'path integration', in which continuously update 'home vector' gives estimated distance direction nest. As path integration accumulates errors, it cannot be relied bring precisely home: such precision accomplished by using views acquired before start foraging. Further learning scaffolded vectors or remembered vectors, guide route help useful experienced way. Many rely olfaction well vision guidance full details paths revealed how mix innate learnt multisensory cues. Wood ants, we focus this review, take an oscillating along pheromone trail sample odours, but acquire visual information only at peaks troughs oscillations. To provide working model neural basis multimodal navigational outline anatomy functioning major central brain areas circuits - complex, mushroom bodies lateral accessory lobes involved coordination behaviour olfactory patterns. Because brains not yet well-studied, work done notably, Drosophila, silkworm moths bees derive plausible circuitry can deliver ants' strategies.

From egg to adult: a developmental table of the antMonomorium pharaonis

bioRxiv (Cold Spring Harbor Laboratory), Год журнала: 2020, Номер unknown

Abstract Ants are one of the most ecologically and evolutionarily successful groups animals exhibit a remarkable degree phenotypic diversity. This success is largely attributed to fact that all ants eusocial live in colonies with reproductive division labor between morphologically distinct queen worker castes. Yet, despite over century studies on caste determination evolution ants, we lack complete ontogenetic series from egg adult for any ant species. We therefore present developmental table Pharaoh Monomorium pharaonis , species whose simultaneously produce both queens completely sterile workers. In total, M . embryonic, larval, pupal development lasts 45 days. During embryogenesis, majority events conserved fruit fly Drosophila melanogaster However, discovered two types same-stage embryos prior gastrulation: (1) internalized germ cells; (2) cells outside blastoderm at posterior pole. Moreover, found two-types following band extension: fertile primordial no cells. Together, our data shows (fertile) (sterile) phenotypes already determined differentiated by early embryogenesis. larval development, previous find 3 instars reproductives there considerable variation within each caste-specific instar, making it difficult lineate instar boundaries. Here, propose anatomical markers can segregate larvae into gyne (unmatted queen), male castes, including during 1 st instar. Overall, hope here will serve as blueprint generation future tables.
