Species of elephants, lions and other animals targeted by trophy hunters and poachers looking for the biggest, most impressive horns and antlers, have less of an ability to adapt to climate change, according to a new study by researchers at Queen Mary University.

The reason: Impressive antlers, manes and other characteristics can indicate how well an animal is doing overall, which can also mean they are better genetically equipped for their environment. "They also father a high proportion of the offspring. But if they're killed before they can spread their 'good genes' around, this reduces the overall fitness and resilience of that population," the study's lead author Robert Knell told National Geographic.

Yes, but: Knell said properly managed trophy hunting can be an asset to conservation, which is why the group is not calling for a ban. One suggestion may be to restrict the age at which a trophy animal can be hunted in order to give them time to pass on their genes to the next generation and the population more broadly.

In other studies: David Coltman, a biological science professor at University of Alberta, said that the results from Knell's study using a computer simulation model matched those of his own on big horn sheep in the Rocky Mountains, where they've seen a 20% decline in the size of the sheep's horns due to decades of trophy hunting.

Big picture: The Fish and Wildlife Service recently lifted a ban on importing hunted elephant trophies from Zimbabwe and Zambia when it can be proved it aided in conservation efforts. The announcement sparked outrage, which led to Trump tweeting and Interior Secretary Ryan Zinke releasing a statement saying permits would be put on hold while the decision about the ban was reviewed.

N.Y. Times faces culture clashes as business booms

New York Times columnist David Brooks' resignation from a paid gig at a think tank on Saturday is the latest in a flurry of scandals that America's biggest and most successful newspaper company has endured in the past year.

Driving the news: Brooks resigned from the Aspen Institute following a BuzzFeed News investigation that uncovered conflicts of interest between his reporting and money he accepted from corporate donors for a project called "Weave" that he worked on at the nonprofit.

America rebalances its post-Trump news diet

Nearly halfway through President Biden's first 100 days, data shows that Americans are learning to wean themselves off of news — and especially politics.

Why it matters: The departure of former President Trump's once-ubiquitous presence in the news cycle has reoriented the country's attention.

2021 sees a record number of bills targeting trans youth

Republicans in at least 25 states have introduced over 60 bills targeting transgender children — a legislative boom since January that has beaten 2020's total number of anti-trans bills.

Why it matters: LGBTQ advocates say the unprecedented push was catalyzed by backlash to Biden's election and the Supreme Court ruling that workers cannot be fired for being gay or transgender.
