It would have been only the second mammal other than the polar bear to be afforded such protection explicitly because of climate change.
Nature Newsa study of sexually scrambled chickens suggests that sex in birds is determined in a radically different way from that in mammals.
This cell-by-cell sex orientation contrasts sharply with the situation in mammals, in which organism-wide sex identity is established through hormones.
because nothing like them has been seen in mammals. In almost all mammals, including humans, embryonic cells are initially sexually indistinguishable.
During development, genetic factors trigger the formation of male or female gonads according to an animal's combination of sex chromosomes (XY for males and XX for females.
Clinton says the work shows that chickens have a fundamentally different way of determining their sex from mammals:

This squirrel-sized dude evolved long before the rise of modern mammals but the hair and fur residue found preserved in its fossil indicate that those traits existed even back in the Jurassic era.
Hair and fur have generally been considered unique to mammals so it's exciting to find that they could have been around even before the first mammals arrived on the evolutionary scene.
This bolsters the 2006 finding of one other pre-mammalian fossil with fur the only other hairy ancestor we've discovered.
and integument had evolved already before the rise of modern mammals says Zhe-Xi Luo one of the fossil's discoverers and a professor of organismal biology and anatomy at the University of Chicago.

When birds and small mammals feed on the fruit they subsequently excrete the indigestible seeds elsewhere
and nylon DEET has been reported to inhibit an enzyme (acetylcholinesterase) in mammals that is important in the nervous system.
In a study spanning two decades the researchers witnessed the near-complete extinction of native small mammals on forest islands created by a large hydroelectric reservoir in Thailand.
However the researchers saw native small mammals vanish with alarming speed with just a handful remaining--on average less than one individual per island--after 25 years.
Native mammals suffered the harmful effects of population isolation and they also had to deal with a devastating invader--the Malayan field rat.
In just a few years the invading rat grew so abundant on the islands that it virtually displaced all native small mammals.

but is thought otherwise to be rare in mammals. If kinship-based social dynamics were playing a critical role in these pilot whale strandings first we would expect to find that the individuals in a stranding event are in fact all related to each other.
Often stranded calves are refloated with the nearest mature females under the assumption that this is the mother explained Scott Baker co-author and Associate Director of the Marine Mammal Institute at Oregon State university.
In this study Murray and colleagues fed young pigs milk from goats that were modified genetically to produce in their milk higher levels of lysozyme a protein that naturally occurs in the tears saliva and milk of all mammals.
