Biodiversity

"A sudden drop in the number of red knots visiting the beaches of Delaware Bay during migration this spring has renewed concern among scientists about the survival of the threatened shore bird’s Atlantic Coast population." "Every May, these birds stop in the Delaware Bay on their way to Arctic Canada. But a shortage of food this season puts their flight at risk."

"Poaching of the big cats is on the rise, and a new study links their slaughter to corruption as well as investment from Chinese companies."

"Luminous yellow and blue fish dart through the fragments of coral hanging from rows of pipes anchored to the seabed in Guanahacabibes, in western Cuba, while scientists in diving gear annotate their observations on waterproof clipboards."

"It has long been our planet’s greatest and oldest murder mystery. Roughly 445 million years ago, around 85 percent of all marine species disappeared in a geologic flash known as the Late Ordovician mass extinction. But scientists have long debated this whodunit, in contrast to clearer explanations for Earth’s other mass extinctions."

"An environmental group on Tuesday said it will sue the White House if President Trump doesn’t walk back an executive order that waives endangered species protections along with a host of other environmental laws."

"First, there were murder hornets. Now, invasive, poisonous toads are the latest bizarre creature to go wild in the U.S. As South Florida enters its wet season aka hurricane season, the cane toad—an ugly, warty, brown amphibian with poison can kill pet dogs—is thriving. That’s not only concerning for pet owners. These toads are highly destructive to the environment."

"The [Chinese] government has moved slowly to permanently stop the sale and consumption of wild animals in the wake of the coronavirus epidemic, raising fears the practice may continue."

"Master builders of the sea construct the equivalent of a complex five-story house that protects them from predators and funnels and filters food for them — all from snot coming out of their heads."

"We talk with#BlackBirdersWeek co-founder Chelsea Connor about how black birders are changing the narrative around who gets to enjoy nature and the challenges black birders face."

"We are in the midst of a mass extinction, many scientists have warned — this one driven not by a catastrophic natural event, but by humans. The unnatural loss of biodiversity is accelerating, and if it continues, the planet will lose vast ecosystems and the necessities they provide, including fresh water, pollination, and pest and disease control."
