GALEA SPIXII PDF

The aim of this work was to investigate the thermal biology of the Spix's yellow-toothed cavy Galea spixii from the hot and dry environment of the Brazilian Caatinga by infrared thermography and biophysical equations. We monitored the rectal temperature, as well as the non-evaporative radiative and convective pathways and evaporative heat exchanges of males and females. The mean rectal temperature of females and males was We identified thermal windows by infrared thermography. The surface temperatures and the long-wave radiation heat exchanges were higher in the periocular, preocular, pinnae and vibrissae regions, in that order.

Spix's yellow-toothed cavy

The aim of this study was to evaluate the phases of sexual development and spermatogenesis of Spix's yellow-toothed cavy Galea spixii based on analyses of the structural components of the testes. The testes of animals from 0 to days of age were collected by orchiectomy, weighed, and processed for analysis by light microscopy. At 45 days of age, spermatozoa were seen in the tubular lumen. Spermatogenesis was not established in animals from 45 to days of age. The stages of sexual development may be classified into the following phases: from birth to the age of 15 days immature ; 30 days of age prepubertal ; days of age pubertal ; and and days of age postpubertal. This is the first study to address the male reproductive biology of Spix's yellow-toothed cavy. This site needs JavaScript to work properly.

Development of Spermatogenesis in Captive-Bred Spix's Yellow-Toothed Cavy (Galea Spixii)

Spix's yellow-toothed cavy Galea spixii is a rodent , a cavy species from South America. Galea spixii and G. It is the most stable species within the Galea group because it is extremely abundant throughout its range. Gestation is about fifty days. Litters size ranges from one to five, with an average of three.
