Researchers found evidence of inbreeding and small colonies in rusty patched bumblebee populations. A first-of-its-kind rangewide genetic study of the endangered rusty patched bumblebee found ...
The conservation status of orcas varies by population. Some groups are considered endangered due to threats like pollution, habitat loss, and reduced prey availability. Current estimates suggest that ...
Inbreeding is the mating of individuals or organisms that are genetically closely related, resulting in increased homozygosity and consequently an increase in the occurrence of recessive traits ...
Two more black-footed ferrets have been cloned from the genes used for the first clone of an endangered species in the U.S., bringing to three the number of slinky predators genetically identical ...
Newly published science suggests orcas may be not just one but three distinct species. Researchers say that, based on what they've found, the killer whales deep in the Pacific Ocean should get ...
Although both types live in the eastern North Pacific, they have different diets: the resident orcas eat fish, with a particular predilection for salmon, while the Bigg’s orcas hunt marine ...
Orcas are actually large dolphins, and for decades people have sought to profit off of killer whales, even when it has put ...
All hail Chainsaw: the big guy with the jagged dorsal fin who, together with his fellow Bigg’s killer whales, has already racked up a record number of sightings of the orcas for 2023.
Three animals resembling gray wolves were recently spotted in Nevada, and if suspicions are confirmed, this would be the first time in more than a century that the endangered species has been seen ...
The Coast Guard and others are using a new system to track endangered whales in the Pacific Northwest. It's a kind of early warning traffic control center for ships so they don't get too close to ...
We all understand the concept of inbreeding in human terms – where people who are too genetically similar reproduce, resulting in offspring with deformities. With each inbred generation ...
The two orca types include Bigg’s killer whales, which have a healthy, growing population and feed on other marine mammals, and residents, which encompass the endangered southern residents that ...
