Dracula ant phylogeny as inferred by nuclear 28S rDNA sequences and implications for ant systematics (Hymenoptera: Formicidae: Amblyoponinae).
Ants are one of the most ecologically and numerically dominant families of organisms in almost every terrestrial habitat throughout the world, though they include only about 1% of all described insect species. The development of eusociality is thought to have been a driving force in the striking diversification and dominance of this group, yet we know little about the evolution of the major lin...
متن کاملPhylogenetic relationships among species groups of the ant genus Myrmecia.
Phylogenetic relationships among the nine species groups of the predominately Australian ant genus Myrmecia were inferred using 38 Myrmecia species and an outgroup using DNA sequences from two nuclear genes (622nt from 28S rRNA and 1907nt from the long-wave opsin gene). Nothomyrmecia macrops was selected as the most appropriate outgroup based on recent reliable studies showing monophyly of Myrm...
متن کاملMolecular identification of Dicrocoelium dendriticum using 28s rDNA genomic marker and its histopathologic features in domestic animals in western Iran
Introduction: Dicrocoeliasis is a common disease of bile ducts and gallbladder of domestic and wild ruminants. This disease is caused by different species of dicrocoelium including Dicrocoelium dendriticum. The aim of this study was to identify pathological damages and molecular features associated with this parasite in ruminants. Materials and Methods: In this cross-sectional study, 180 fresh...
متن کاملForaging behavior in the ant genus Messor (Hymenoptera: Formicidae: Myrmicinae)
The genus Messor consists of 113 species of seed harvesting ants that are found in grasslands, semi-arid areas and savannahs in both the Old and New World. A full spectrum of foraging strategies occurs in Messor, ranging from individual to group foraging, with the latter having evolved several times. This paper reviews foraging strategies and the underlying behavioral mechanisms found in specie...
متن کاملIndividual foraging patterns of the jack jumper ant Myrmecia croslandi (Hymenoptera: Formicidae)
In ants, we know most about the foraging patterns at the colony level. We know surprisingly little about the foraging behaviour of individual foragers and how they shape the behaviour of the colony. To identify spatial and temporal variation in foraging behaviour at the individual level, we studied at two nests the solitary foragers of the Australian jack jumper ant Myrmecia croslandi TAYLOR, 1...
