Wonderfull great site http://problemlosarna.nu/stmap_e9210.html?flonase.keppra.famciclovir.cialis spicelandmedication.com That's not true for mammals, though. Raising young internally limits the number you can produce from a single mating, while the extensive post-natal care required by mammalian young ensures that the female has to stick around for a while after giving birth. But males don't always participate in postnatal care, so it probably shouldn't be a surprise to learn that there are mammals out there that engage in what researchers are terming "suicidal reproduction." The problem is that the behavior only occurs in a small number of marsupial species, and researchers have been arguing for 30 years about why that is the case. Now, some Australian researchers have come up with an answer: a combination of sperm competition and promiscuous females.
