Abstract Properties of the local internal environment of the adult brain are tightly controlled
providing a stable milieu essential for its normal function. The mechanisms involved in this …

A comparative assessment of aging and longevity in mammals has four uses in aging
research. These are:(1) hypothesis formulation and evaluation,(2) investigating the …

Computer simulation is a valuable tool in the genetic management of captive populations. It
can be used to assess the extent of genetic variability in a colony, to predict the risk of future …

This study was conducted to explore the involvement of DNA damage in the suppression of
contact hypersensitivity (CHS) by UV irradiation. The opossum, Monodelphis domestica …

The development of the neocortex of the marsupial Monodelphis domestica has been
studied from birth until adulthood. Monodelphis is born after a gestational period of 14 days …

The pattern of onset and general rate of cranial ossification are compared in two marsupials,
Monodelphis domestica (Didelphidae) and Macropus eugenii (Macropodidae). In both …

Community structure, macrohabitat selection, and patterns of species co-occurrence were
examined during a 14-month study of small mammals in the Cerrado Province of central …

Biologists have long studied the evolutionary consequences of the differences in
reproductive and life history strategies of marsupial and eutherian mammals. Over the past …

The timing of development was examined in 496 embryos from female Monodelphis
domestica, collected at known time intervals after video recorded mating. Ovulation occurred …

A fascinating look at the diverse reproductive strategies of numerous female mammals, from
hyenas to goats, kangaroos to whales. Newborn mammals can weigh as little as a dime or …
