Terrestrial mammal feces: a morphometric summary and description.
نویسنده
چکیده
The study of feces of terrestrial mammals brings out biological and ecological data such as the species presence, diet, behaviour, territory, parasitic fauna, and home-range use, which can be applied for conservation projects and support paleoecological research that use coprolites as the main source of study. Although the new biotechnological techniques allow more accurate data, the diagnosis based on morphometric analyses permits the primary identification of the taxonomic group origin to support the best choice of subsequent analyses. We present the compilation list of fecal shape and measurements available in the literature published in North America, Eastern and Southern Africa, Europe, and new data from Brazil. Shape and diameters are the best characteristics for taxonomic identification. Feces were assembled in 9 groups that reflect the Order, sometimes the Family, and even their common origin.

The echolocation ability of several dolphin species is well documented, but little is known about hearing characteristics of most marine mammals. This paper describes the major features of the peripheral auditory system in both large and small whales and presents a three-dimensional morphometric analysis of the inner ear in 12 species. Correlation analyses of inner ear morphometry vs. hearing c...
متن کاملA Morphometric Study of the Effects of Bilateral Vasectomy on Testis in Rats
SUMMARY The testes of five wistar rats 2 months after bilateral vasectomy was compared with those of shamoperated controls. Aims were to determine whether there are any changes in the wistar rat testis after vasectomy. Two testis in the vasectomized group displayed histological changes, which consisted of depletion of germ cells, vacuolation in the epithelium, folding of basement membrane ...
متن کاملAttractiveness of Native Mammal’s Feces of Different Trophic Guilds to Dung Beetles (Coleoptera: Scarabaeinae)
Mammal feces are the primary food and nesting resource for the majority of dung beetle species, and larval development depends on the quantity and quality of that resource. Physiological necessities, competitive interactions, and resource sharing are common and suggest that dung beetles may show preferences for feces of greater nutritional quality, which may in turn impact beetle assemblages an...
متن کاملIdentification of Gyrodactylus gurleyi in Carassius auratus using morphometric and molecular characterization
BACKGROUNDS: Gyrodactylus is a small monogenean ectoparasite that lives on the skin and fins of most of the world's fish species. Gyrodactylus appears to be one of the most prevalent parasites found in ornamental fish, especially in Cyprinids. Goldfish (Carassius auratus) are a popular ornamental fish that are highly contaminated by Gyrodcatylus. OBJECTIVES: The present study is aimed to identi...
