"Alien invasion": Researchers identify which exotic animals may soon hitchhike into Australia
Australia is renowned for its native flora and fauna, but did you know the continent is also home to about 3,000 "alien" species of animals, plants, fungi and microbes?.....»»
Online sales of a wild bat sold as décor threaten species
A fiery orange bat, its wings folded and tiny teeth forever bared on its fuzzy face, is mounted inside a 6-inch, black coffin. Its retail price: $59. Or, for $140, you can get one framed with its black and orange wings spread, deliverable in two days.....»»
Asexual reproduction usually leads to a lack of genetic diversity. Not for these ants
Genetic diversity is essential to the survival of a species. It's easy enough to maintain if a species reproduces sexually; an egg and a sperm combine genetic material from two creatures into one, forming a genomically robust offspring with two disti.....»»
The salmon diaries: Life before and after Klamath Dam removal
When salmon return from the ocean to the Klamath River after the world's largest dam removal project ends this fall, they will regain access to 400 miles of historical spawning habitat their species has been cut off from for more than a century......»»
World"s rarest whale may have washed up on New Zealand beach, possibly shedding clues on species
Spade-toothed whales are the world's rarest, with no live sightings ever recorded. No one knows how many there are, what they eat, or even where they live in the vast expanse of the southern Pacific Ocean. However, scientists in New Zealand may have.....»»
Ladybugs: Understanding the beneficial predators among us

Impacts of extreme drought on forest ecosystems reveal species-specific adaptation differences in Northeast China
A recent study from China has shed light on the profound impacts of extreme droughts on forest ecosystems, particularly in water-limited regions. The findings revealed significant differences in how various tree species respond to such stressors......»»
Exploring three-dimensional quantum Griffiths singularity in bulk unconventional iron-based superconductors
Exploration of exotic quantum phase transitions has always been a focus in condensed matter physics. Critical phenomena in a phase transition are entirely determined by the universality class, which is controlled by the spatial and/or order-parameter.....»»
Evolutionary biologists investigate how plant cold specialists can adapt to the environment
Plant cold specialists like the spoonworts have adapted well to the cold climates of the Ice Ages. As cold and warm periods alternated, they developed a number of species that also resulted in a proliferation of the genome......»»
