Standard and digestive metabolism in the banded water snake, Nerodia fasciata fasciata.
Estimating energy costs by respirometry is fundamental to many studies of the ecology, behavior and evolution of reptiles. However, traditional respirometry procedures seldom incorporate objective techniques for removal of outliers from estimates of metabolic parameters. We demonstrate how computer-automated respirometry equipment, which records many respiratory measurements over short interval...
متن کاملEcologic Drivers and Population Impacts of Avian Trichomonosis Mortality Events in Band-tailed Pigeons (patagioenas Fasciata) in California, Usa.
: Avian trichomonosis, a disease typically caused by the protozoan parasite Trichomonas gallinae , is a well recognized cause of death in many avian species. In California, US, trichomonosis has caused periodic epidemics in Pacific Coast Band-tailed Pigeons ( Patagioenas fasciata monilis). We summarize reported mortality events and investigate ecologic drivers and population impacts associate...
متن کاملTrichomonas stableri n. sp., an agent of trichomonosis in Pacific Coast band-tailed pigeons (Patagioenas fasciata monilis)☆
Trichomonas gallinae is a ubiquitous flagellated protozoan parasite, and the most common etiologic agent of epidemic trichomonosis in columbid and passerine species. In this study, free-ranging Pacific Coast band-tailed pigeons (Patagioenas fasciata monilis) in California (USA) were found to be infected with trichomonad protozoa that were genetically and morphologically distinct from T. gallina...
متن کاملPhotoreceptor fine structure in the southern fiddler ray (Trygonorhina fasciata).
The fine structure of the retinal photoreceptors has been studied by light and electron microscopy in the southern fiddler ray or guitarfish (Trygonorhina fasciata). The duplex retina of this species contains only rods and single cones in a ratio of about 40:1. No multiple receptors (double cones), no repeating pattern or mosaic of photoreceptors and no retinomotor movements of these photorecep...
متن کاملAn electrophysiological study of parapodial innervation patterns in Aplysia fasciata.
Parapodial extensions of the foot are particularly well developed in Aplysia fasciata, in which species they function during swimming. As was indicated in earlier studies (Hughes & Tauc, 1962), many of the nerves which innervate the foot sensu stricto of other species supply the parapodia of Aplysia fasciata. In fact there is no detailed account of the branching of the nerves in A. fasciata; Ma...
