The critical thermal maximum: data to support the onset of spasms as the definitive end pointWe provide data to support the onset of spasms (OS) as the definitive end point for determining thermal tolerance with the critical thermal maximum (CTMax). We measured the CTMax of 610 animals in three vertebrate classes, Actinopterygii, Amphibia, and Reptilia. All showed a significantly lower mean loss of righting response (LRR) than OS. Statistical evaluation of the variability associat... ... hiện toàn bộ

RESPIRATION OF FISHES WITH SPECIAL EMPHASIS ON STANDARD OXYGEN CONSUMPTION: II. INFLUENCE OF WEIGHT AND TEMPERATURE ON RESPIRATION OF SEVERAL SPECIES Standard oxygen consumption, as estimated by simultaneously measuring spontaneous activity and oxygen consumption, for five species of freshwater fishes, was measured in relation to weight and temperature. The fish studied were brown trout, Sulmo trutta; brook trout, Salvelinus fontinalis; common white sucker, Catostomus commersonii; brown bullhead, Ictalurus nebulosus; and carp, Cyprinus... ... hiện toàn bộ

Ecological interactions of marine spongesSponges interact with most other organisms in marine systems as competitors, symbionts, hosts of symbionts, consumers, and prey. Considerable creative energy has been required to study and describe the amazing variety of sponge interactions, as sponges can hide symbionts deep inside, rapidly regenerate wounds from grazers, carry on important associations with unculturable microscopic organ... ... hiện toàn bộ

Ecology and evolution of sympatric sticklebacks (Gasterosteus): morphological and genetic evidence for a species pair in Enos Lake, British Columbia Two morphological forms of three-spined stickleback (Gasterosteus) coexist in Enos Lake near Nanoose Bay, Vancouver Island. For convenience, the two forms are referred to as "benthics" and "limnetics." Morphological and biochemical characteristics of the two forms were examined and artificial hybrids (F1 and F2 ) reared in the laboratory. The two f... ... hiện toàn bộ

An experimental study of carbon-isotope fractionation between diet, hair, and feces of mammalian herbivoresThe carbon-isotope composition of hair and feces offers a glimpse into the diets of mammalian herbivores. It is particularly useful for determining the relative consumption of browse and graze in tropical environments, as these foods have strongly divergent carbon-isotope compositions. Fecal δ13 C values reflect the last few days consumption, whereas hair provides longe... ... hiện toàn bộ

The implications of bite performance for diet in two species of lacertid lizardsOne of the performance features that is generally considered crucial to increasing the potential prey spectrum of lizards is bite capacity. In this study we tested whether bite forces may serve as a basis for diet selection in two syntopically occurring lacertid lizards. We did so by measuring bite forces in vivo for a large sample of lizards of the species Podarcis muralis and Lacerta viv... ... hiện toàn bộ

Distribution of the avian hematozoa of North America The literature pertaining to the prevalence of avian hematozoa in North America, north of Mexico, together with unpublished records from the files of the International Reference Centre for Avian Malaria Parasites, have been collated and analyzed with respect to the distribution of parasite genera by region, host family, and vertical stratification of nesting sites. The blood parasites of ... ... hiện toàn bộ

Individual recognition by song in white-throated sparrows. I. Discrimination of songs of neighbors and strangers Playback of recorded songs of white-throated sparrows (Zonotrichia albicollis) to territorial males elicited a stronger response to songs of strangers than to songs of territorial neighbors. Responses to a bird's own song were intermediate. All test songs were played on the territorial boundary adjacent to the neighbor used in the experiment. Peak of response by song occurred in the 1st m... ... hiện toàn bộ

Ecology and natural history of the protochordatesThe last comprehensive reviews of ecology and natural history of ascidians were included in the excellent 1971 publication by Millar on the biology of ascidians and the 1991 treatise on New Caledonia ascidians by Monniot, Monniot, and Laboute. Several hundred papers have been published since that time, greatly expanding our knowledge of environmental tolerances and responses to increasing ... ... hiện toàn bộ

The chemical ecology and evolution of bee–flower interactions: a review and perspectivesThe present review is one in the special series of reviews on animal–plant interactions.Bees and angiosperms have shared a long and intertwined evolutionary history and their interactions have resulted in remarkable adaptations. Yet, at a time when the “pollination crisis” is of major concern as natural populations of both wild and honey bees ( Apis mellifera L., 1758) face alarming decline rates at a worldwide scale, there are important gaps in our understanding of the ecolo... ... hiện toàn bộ
