Widespread Wolbachia infection in terrestrial isopods and other crustaceans
Wolbachia bacteria are obligate intracellular alpha-Proteobacteria of arthropods and nematodes. Although widespread among isopod crustaceans, they have seldom been found in non-isopod crustacean species. Here, we report Wolbachia infection in fourteen new crustacean species. Our results extend the range of Wolbachia infections in terrestrial isopods and amphipods (class Malacostraca). We report...
متن کاملCrustaceans
between species, but between different segments on the same animal. They have limbs specially adapted for walking, eating, grooming, swimming, mating, sensing the surrounding environment, brooding young, spearing prey, scraping surfaces and even snapping to make noise. Lobsters provide a good example of the limb diversity that can exist on even a single individual — the thoracic and abdominal a...
متن کاملPancrustacean phylogeny: hexapods are terrestrial crustaceans and maxillopods are not monophyletic.
Recent molecular analyses indicate that crustaceans and hexapods form a clade (Pancrustacea or Tetraconata), but relationships among its constituent lineages, including monophyly of crustaceans, are controversial. Our phylogenetic analysis of three protein-coding nuclear genes from 62 arthropods and lobopods (Onychophora and Tardigrada) demonstrates that Hexapoda is most closely related to the ...
متن کاملPost-exercise Lactate Production and Metabolism in Three Species of Aquatic and Terrestrial Decapod Crustaceans
Aquatic and terrestrial crustaceans are dependent on both aerobic and anaerobic metabolism for energy production during exercise. Anaerobic energy production is marked by an accumulation of lactate in both muscle tissue and haemolymph, but the metabolic fate of lactate is not clear. Lactate recycling via gluconeogenesis and the potential role of carbonic anhydrase (CA) in supplying bicarbonate ...
متن کاملPolarisation Vision of Crustaceans
The photoreceptor design of crustaceans, often containing regular arrays of intrinsically polarisation-sensitive microvilli, has had a profound influence on the visual biology of this subphylum. The land-based arthropods (insects and arachnids) also construct photoreceptors from ordered microvilli; however while in many species polarisation sensitivity results, a general overview of these group...
