New research suggests that populations of the Northern Cardinal -- one of the most ubiquitous backyard birds in the United States -- are undergoing speciation in two adjacent deserts. This study, which analyzed genetics and vocal behavior, gives clues about the early steps in bird speciation.
Using long-term data from the "Butterfly Monitoring Germany" citizens' research project, scientists have now investigated the matter using butterflies as an example. According to the research, there are more butterfly species in Natura 2000 areas than elsewhere. However, the same decline in the numbers of species regardless whether the communities are located within or outside the protected areas.
Researchers at the NC Museum of Natural Sciences and NC State University, running a large-scale camera-trap study called eMammal, recently enlisted the help of K-12 students from 28 schools and four countries -- the United States, India, Mexico and Kenya. What the researchers, and the kids, discovered was surprising. 'These camera traps yielded thousands of images with a total 83 native mammal species, including 12 that were threatened or endangered,' says lead author Stephanie Schuttler.
Urban hummingbird feeders are highly prevalent. UC Davis veterinary researchers want to understand the health implications for birds congregating and sharing food resources at these bird buffets. Data from a new study using RFID technology is one piece of that puzzle.
A recent study of textbooks aimed at introductory biology courses finds that they devote less than one percent of their text to discussing insects, which make up more than 60 percent of animal species. The study authors argue that this provides a poor foundation for understanding ecosystems, biodiversity, and other core aspects of biological research.
Red wolves, once nearly extinct, again teeter on the abyss. New research finds red wolf ancestry in Texas -- providing opportunities for additional conservation action and difficult policy challenges. Michigan Tech researcher Kristin Brzeski and others have identified red wolf "ghost alleles" in canid population on Galveston Island.
The world's primary archive of tree ring data, which holds more than 52 million cost-free records spanning 8,000 years of history, has gotten a makeover by scientists from four countries committed to making science more accessible. The International Tree Ring Data Bank, developed in 1974 and populated by hundreds of contributing scientists and agencies, had only been used for a handful of studies at a global scale due to inconsistent data accessibility and formatting.
The fauna in the Antarctica could be in danger due the pathogens humans spread in places and research stations in the southern ocean, according to a study led by the experts Jacob González-Solís, from the Faculty of Biology and the Biodiversity Research Institute (IRBio) of the University of Barcelona, and Marta Cerdà-Cuéllas, from the Institute of Agrifood Research and Technology (IRTA-CReSA).
Invasive species and habitat loss are the biggest threats to Australian biodiversity, according to new research by the Threatened Species Recovery Hub in partnership with The University of Queensland. Lead researcher Stephen Kearney from UQ's School of Earth and Environmental Sciences said Australia was rich in unique biodiversity, but has had a poor track record since European settlement.
The future of the world's coral reefs is uncertain, as the impact of global heating continues to escalate. However, according to a study published today in Nature Climate Change, the response of the Great Barrier Reef to extreme temperatures in 2017 was markedly different to one year earlier, following two back-to-back bouts of coral bleaching.
