Fasting metabolism and thermoregulatory competence of the star-nosed mole, Condylura cristata (Talpidae: Condylurinae).
Metabolic and body temperature (Tb) responses of star-nosed moles (Condylura cristata) exposed to air temperatures ranging from 0 to 33 degrees C were investigated. The thermoneutral zone of this semi-aquatic mole extended from 24.5 to 33 degrees C, over which its basal rate of metabolism averaged 2.25 ml O2 g-1 h-1 (45.16 J g-1 h-1). This rate of metabolism is higher than predicted for terrest...
متن کاملThe superior and inferior colliculi of the mole (Scalopus aquaticus machrinus).
This investigation is a study of the afferent and efferent connections of the tectum of the midbrain in the mole (Scalopus aquaticus machrinus). An attempt is made to correlate these findings with the known habits of the animal. A subterranean animal of the middle western portion of the United States, Scalopus aquaticus machrinus is the largest of the genus Scalopus and its habits have been mor...
متن کاملCoccidian parasites (Apicomplexa: Eimeriidae) from insectivores. VIII. Four new species from the star-nosed mole, Condylura cristata.
Twenty-four star-nosed moles, Condylura cristata, collected from the northeastern United States (Maine, Massachusetts, Ohio, Vermont) were examined for coccidian oocysts. All of the moles were infected with from 1 to 4 species of coccidia representing 2 eimerian and 3 isosporan spp., but oocysts of only 4 of these species were present in sufficient numbers for detailed study; these are describe...
متن کاملBody oxygen stores, aerobic dive limits and diving behaviour of the star-nosed mole (Condylura cristata) and comparisons with non-aquatic talpids.
The dive performance, oxygen storage capacity and partitioning of body oxygen reserves of one of the world's smallest mammalian divers, the star-nosed mole Condylura cristata, were investigated. On the basis of 722 voluntary dives recorded from 18 captive star-nosed moles, the mean dive duration (9.2+/-0.2 s; mean +/- S.E.M.) and maximum recorded dive time (47 s) of this insectivore were compar...
متن کاملThe development of a biological novelty: a different way to make appendages as revealed in the snout of the star-nosed mole Condylura cristata.
The nose of the star-nosed mole Condylura cristata is a complex biological novelty consisting of 22 epidermal appendages. How did this new set of facial appendages arise? Recent studies find remarkable conservation of the genes expressed during appendage formation across phyla, suggesting that the basic mechanisms for appendage development are ancient. In the nose of these moles, however, we fi...
