Environmentalists say exploratory drilling could release harmful chemicals into the surrounding wetlands and rivers.

The death of the animal is the latest case in what officials have called an "Unusual Mortality Event" that has been ongoing among North Atlantic right whales since 2017.

The hornets represent a significant threat to Western honeybees, which have no innate defence against them.

Invasive species spread around the globe with the help of human activities, such as global trade and transportation.

Microplastic pollution is ubiquitous, but the processes that distribute the particles between marine, terrestrial and atmospheric environments around the planet remain poorly understood.

An aquarium owner noticed his sea urchins covering themselves with rocks and other objects, so he started 3D printing goofy hats. But a marine biologist confirms that sea urchins are making more than fashion statements.

The most extensive investigation to date finds global insect numbers drop 0.92 percent a year. However, the world's freshwater insects, like mayflies, are bucking the trend and seeing numbers rise.

"This type of feeding is very risky, as dolphins run the risk of remaining stranded," said researcher Daniele Cagnazzi.

A vulnerable population of wolves living on Prince of Wales Island lost 97 percent of the population during the 2019-2020 trapping season.

Some experts think that the hole formed as a result of natural processes, while others argue that humans may be partly to blame.

Large herbivores dominated the Earth's land ecosystems for several million years before suffering significant extinctions and declines over the past 100,000 years or so.

"We have new species turning up that are already contaminated and so we have missed the window to understand these species in a natural environment," said marine ecologists Alan Jamieson.

"The extinction crisis gets worse by the day, but Trump officials are twiddling their thumbs as plants and animals fade away," said Noah Greenwald from the Center for Biological Diversity.

"If allowed to spread, crazy worms could cause serious damage to horticultural crops and the forest ecosystem in Maine," the state's Department of Agriculture, Conservation and Forestry said.

"The most interesting about bees is their communication," said entomologist Morgan Carr-Markell.

Earth's tropical forests are "time capsules" of human history stretching back hundreds of years.

"It just seems to me that every bat in Australia is now in Ingham," Raymon Jayo, mayor of Hinchinbrook, said.

The drug lord imported four hippos into the country, which were housed in his private zoo.

"It's very exciting for us to find this young snake," researcher Jim Godwin from Auburn University said.

"I am honored to welcome our canine friends back to Colorado after their long absence," Colorado Governor Jared Polis said.

"The ecological impact of Native Americans before European arrival has been debated for decades," researcher Wyatt Oswald said.

Significant fire outbreaks in the Amazon, Australia and the Arctic Circle—among others—made headlines around the world this year.

"Our thoughts are with the people and biodiversity in this tragedy," Diana Bell—a professor of Conservation a Biology—said

The Earth is in the grips of what scientists have dubbed the "Sixth Mass Extinction" with the global rate of species extinction at least "tens to hundreds of times higher" than the average over the past 10 million years.

While some of the salamanders survived in the bells for 19 days, others went from alert, active and swimming in the pitcher fluid to dead in three days.

Researchers predict that the average total body mass of mammals will drop by 25 percent over the next century.

Opportunistic sharks feast on migrating birds, scientists believe.

Mark Boyce has spent 40 years studying the park's ecosystems and says wolf reintroduction has been fascinating.

An international team examined sudden ecological transitions throughout Earth's history.

The Gaia hypothesis proposes that life, through its interactions with the Earth's crust, oceans, and atmosphere, produced a stabilising effect which has enabled it to survive under conditions which would have wiped it out on non-regulating planets.
