The alligator snapping turtle held menace enough in its massive, gaping jaws, which ended in a sharp beak poised like the fangs of an agitated rattlesnake. Its long, plump claws dug into the sand above thorny, wrinkled skin and a deeply-ridged carapace about the size of a large dinner platter.
AAAS Kavli winner tackles conservation in era of upheaval.
Covering conservation and the environment can be quite depressing at times, writer Hillary Rosner told students at Northwestern University’s Medill School of Journalism recently, but stories about climate change, endangered species, disappearing rainforests, and other topics demand astute and sustained attention.
The humpback whale calf is so new that its dorsal fin and tail flukes appear soft and flimsy, and its mother is still excreting blood, while sometimes supporting the calf on her back. The rare video minutes after birth was captured by the University of Hawaiii at Manoa’s Marine Mammal Research Program (MMRP) in January 2019.

While soybean farmers watched the drift-prone weed killer dicamba ravage millions of acres of crops over the last two years, Arkansas beekeeper Richard Coy noticed a parallel disaster unfolding among the weeds near those fields.
When Coy spotted the withering weeds, he realized why hives that produced 100 pounds of honey three summers ago now were managing barely half that: Dicamba probably had destroyed his bees’ food.

As far as anyone can tell, the cold-water crayfish Faxonius eupunctus makes its home in a 30-mile stretch of the Eleven Point River and nowhere else in the world. Because the animal is being considered for endangered species status, researchers are comparing old and new techniques to get a thorough accounting of its population and distribution.

Non-native milkweed species planted in the southern U.S. could harm monarch butterflies as temperatures rise.
When a team of scientists analyzed two dozen environmental factors to understand bumblebee population declines and range contractions, they expected to find stressors like changes in land use, geography or insecticides. Instead, they found a shocker: fungicides, commonly thought to have no impact.

Summary: A new study shows that mosquitoes can rapidly learn and remember the smells of hosts and that dopamine is a key mediator of this process. The study proved a mosquito’s preference can shift if that person’s smell is associated with an unpleasant sensation.
