Blue Cavern Point on the eastern edge of Santa Catalina Island, some 25 miles off the coast of San Pedro, California, is a hotbed of life. In the shallow edges of the water cling starfish, sea urchins and sea cucumbers. Farther out in deeper seas, bright orange garibaldi and giant sea bass the size of pianos make their home in rippling forests of giant kelp reaching hundreds of feet from the ocean's surface to its floor.
Caecilians have arrived in Miami. Florida Fish and Wildlife biologists captured one of the obscure legless amphibians in the Tamiami canal, the first example of an introduced caecilian in the U.S.
Counting feels utterly effortless to adults, who are unlikely to even remember when or how they picked up this useful, apparently automatic skill. Yet when you think about it, counting is a remarkable invention. It helped early humans to trade, apportion food and organize fledgling civilisations, laying the foundations for life as we know it today.
Over the past few weeks, we've received a flurry of emails from concerned people who've seen sick and dead frogs across eastern Victoria, New South Wales and Queensland.
There are huge differences in species numbers among the major branches of the tree of life. Some groups of organisms have many species, while others have few. For example, animals, plants and fungi each have over 100,000 known species, but most others—such as many algal and bacterial groups—have 10,000 or less.
An international team of scientists including Stony Brook University Professor Resit Akcakaya, Ph.D., published a paper in Conservation Biology that for the first time applies the IUCN Green Status of Species, a new Global Standard to measure how close a species' is to being fully ecologically functional across its range, and how much it has recovered thanks to conservation action. Preliminary IUCN Green Status assessments for 181 species are presented in the paper.
Gabon's Ivindo National Park was listed as a UNESCO World Heritage Site on Wednesday in recognition of the nation's success in defending biodiversity and challenging climate change.
A new study raises questions on whether current conservation science and policy for protected areas could be saving more biodiversity—with political and economic expediency often having taken precedence in the past.
Deep-sea mining in international waters could begin in two years—but researchers say this is unnecessary and could cause irreversible damage to marine ecosystems.
Climate conditions play a significant role in the reproductive success of mature female Antarctic krill and are a factor in fluctuations of the population that occur every five to seven years, a new study from Oregon State University has found.
St. Jude scientist Vibhor Mishra, Ph.D., is homing in on the location where important processes in gene regulation occur, and where single-stranded transcripts are converted into double-stranded RNAs (dsRNAs).
Certain species of floral bacteria can enhance pollen germination, according to a study published today from the University of California, Davis in the journal Current Biology."This is the first paper documenting stimulation of pollen germination by non-plants," said first author Shawn Christensen, a doctoral candidate in associate professor Rachel Vannette's laboratory in the Department of Entomology and Nematology. "Nectar-dwelling Acinetobacter bacteria stimulate protein release by inducing pollen to germinate and burst, benefitting Acinetobacter."
New research from the University of Florida explains how a family of bacteria called Yersinia infects the body so successfully.
A new study from CU Boulder finds that hundreds of millions of years ago, small single-celled organisms may have evolved into larger multicellular life forms to better propel themselves through icy waters.
An analysis of the blood types of one Denisovan and three Neanderthal individuals has uncovered new clues to the evolutionary history, health, and vulnerabilities of their populations. Silvana Condemi of the Centre National de la Research Scientifique (CNRS) and colleagues at Aix-Marseille University, France, present hese findings in the open-access journal PLOS ONE on July 28, 2021.
The discovery of a gene that regulates the angle of root growth in corn is a new tool to enable the breeding of deeper-rooting crops with enhanced ability to take up nitrogen, according to an international team of researchers, led by Penn State.
A Concordia-led research team revealed direct evidence of the presence of the African leopard in the Campo Ma'an Conservation Area, southern Cameroon for the first time in more than 20 years.
As the fertilized egg divides, initially undifferentiated cells take on specific functions, becoming more distinct as different tissues and organs emerge. Understanding how hundreds of disparate cell types arise has proven difficult, largely because scientists have lacked the technologies to capture cellular decision making over time.
The spotted lanternfly—an invasive, destructive pest with a wide range of hosts including grapes, apples, hops, maple and walnut—has spread to a growing number of counties in New York state.
Messenger RNA, or mRNA, has been in the news recently as a crucial component of the Pfizer-BioNTech and Moderna COVID-19 vaccines. The nucleic acid looks, for all intents and purposes, like a strand of DNA that has been sliced the long way. It's what's known as single-stranded RNA (ssRNA), and it can be found throughout the natural world.
