An Overview of Sex Selection at Conception in Mammals
Although the mechanisms under which sex ratio is controlled in nature remain unknown, researchers have attempted to treat sperm in an effort to predetermine the sex of the offspring. The methods of sperm separation that have been repeatedly reported to isolate fractions rich in X- or Y-chromosome bearing sperm are serum albumin gradient swim-up and flow cytometry. However, the ability of the se...

What happens when you get rid of P granules? Mutants that fail to partition P granules to the P lineage are viable and fertile, suggesting that P granules are not essential to distinguish soma from germline in embryos. Mutations in individual P-granule components lead to sterility at high temperature and impaired translational control of at least some mRNAs. What happens when germ cells lack al...
متن کاملCool running: locomotor performance at low body temperature in mammals.
Mammalian torpor saves enormous amounts of energy, but a widely assumed cost of torpor is immobility and therefore vulnerability to predators. Contrary to this assumption, some small marsupial mammals in the wild move while torpid at low body temperatures to basking sites, thereby minimizing energy expenditure during arousal. Hence, we quantified how mammalian locomotor performance is affected ...
متن کاملStatus of Large and Medium-sized Mammals at JRBP
Status of Large and Medium-sized Mammals at JRBP Introduction Mammals are an important ecological component of all terrestrial ecosystems (Cole and Wilson 1996). As seed and fruit dispersers they are critical in determining the seed rain, germination potential and establishment of many plant species (Andresen 1999, Jansen et al. 2004). As flower visitors, some mammals, particularly bats and mar...
