A pioneering study published in Oikos has revealed novel insights into how a select group of birds in the Amazon rainforest, known as terrestrial insectivores, is coping with the ever-increasing threats posed by global climate change.
The reintroduced Colorado wolf found dead last month in Larimer County likely died after being attacked by a mountain lion, according to a necropsy conducted by the U.S. Fish and Wildlife Service.
Deforestation in Costa Rica raises the risk of cattle becoming infected with rabies by vampire bats, finds a new study. Emerging Infectious Diseases published the research by disease ecologists at Emory University.
A parasitic worm that can infest the brains of moose appears to be playing a role in the decline of the iconic animal in some regions of North America.
Even in dry times, Waller Creek on The University of Texas at Austin campus is never without water. That's because a significant portion of the water that flows through it—anywhere from 25% to 50%—can be traced to wastewater from leaky city pipes.
Bee and butterfly populations are in decline in major regions of North America due to ongoing environmental change, and significant gaps in pollinator research limit our ability to protect these species, according to a study published May 15, 2024, in the open-access journal PLOS ONE by Sara Souther of Northern Arizona University, US, and colleagues.
A paper published in the CABI Reviews journal has found that climate change is the most prominent threat to pollinators—such as bumblebees, wasps, and butterflies—that are essential for biodiversity conservation, crop yields and food security.
The baobab (Adansonia) is a genus of trees with eight currently extant species and a long history of humans marveling at them. For as much admiration as the baobabs get, there is an equal amount of mystery surrounding their origin.
An emperor penguin's sex determines the nature of their courtship call—male vocalizations are composed of long, slow bursts with lower frequency tones than the female version. But calls of SeaWorld San Diego male penguin E-79 caught the attention of researchers by defying this binary. Also unusual was this penguin's male companion, E-81. The pair "kept company" and sometimes exhibited ritual courtship displays.
Gelatinous zooplankton, including jellyfish and other diverse, nearly transparent organisms, play important roles in marine ecosystems. Climate change is expected to significantly alter their populations and distributions. New research published in Limnology and Oceanography examines their fate in the Arctic Ocean, one of the fastest warming oceans on Earth.
Bats, as the main predator of night-flying insects, create a selective pressure that has led many of their prey to evolve an early warning system of sorts: ears uniquely tuned to high-frequency bat echolocation. To date, scientists have found at least six orders of insects—including moths, beetles, crickets and grasshoppers—that have evolved ears capable of detecting ultrasound.
A nonnative tree-killing insect is invading northern Utah, attacking subalpine fir and potentially triggering yet another die-off of the region's long-stressed conifer forests.
Researchers at Macquarie University have found a significant portion of shark meat sold in Australian fish markets and takeaway shops is mislabeled, including several samples from threatened species.
Research by Royal Holloway, University of London and ZSL has found that a critically endangered bird's biggest threat is being taken from its habitat to be used as a caged bird for its beauty.
