Shark meat from vulnerable species is being processed into cat food for major brands, according to a new study. Researchers from the National University of Singapore used DNA barcoding technology…
Environmental DNA has changed the way conservationists monitor biodiversity. By sequencing the genetic material found in water and soil samples, scientists can study entire ecosystems or detect rare animals too…
The article has been significantly amended in light of challenges to both the research itself and Mongabay's coverage of the journal article. If you get yourself a map of Peninsular…
With humans sending probes to Mars and the sun, one might think we’ve already explored the full extent of our own planet. But scientists say we’ve only begun to find…
A new study has found that the small nation of Gabon is the “last stronghold” for the critically endangered African forest elephant. Researchers reached this conclusion after conducting a DNA-based…
As a fisheries biologist in Indonesia, Andhika Prasetyo connects with fishers by accompanying them on their voyages out to sea. He can always tell from their faces whether the day’s…
To hear an audio reading of this article listen here: The familiar striped skunk of North America (think of the cartoon Pepé Le Pew) has a lesser-known cousin: the spotted…
Scientists have debated the evolution of the world’s five living rhinoceros species ever since Charles Darwin addressed the question in a treatise in the mid-1800s, predating On the Origin of…
When Demian Chapman and his colleague first started setting up underwater cameras on reefs in 2015, the aim was to capture a lot of shark video. But sometimes they got…
When a trio of beaked whales surfaced off Mexico’s Pacific coast, researchers thought they’d found the elusive Perrin’s beaked whale (Mesoplodon perrini), an endangered species that’s never been officially sighted…
Last recorded in 1968, Megaelosia bocainensis, a frog known for its rounded snout and granular skin, was thought extinct until researchers tracked down its environmental DNA in Brazil’s São Paulo state.
Two liters of seawater, or about half a gallon. That’s all that’s needed to detect the presence of sharks in the ocean, according to a new study. A group of…
In 2013, Demian Chapman ambled down the streets in the Sheung Wan district in Hong Kong, where thousands of yellowed shark fins were drying on the sidewalk, or packed in…
Let’s be honest: many conservationists may start their careers with big ambitions. But as they, and their careers, age, those ambitions — especially in light of the Anthropocene — understandably…
In September 2014, Nepali zoologist Madhu Chetri asked his professor Morten Odden a strange question during their fieldwork. "Are you tired?" he asked Odden as the duo from the Inland…
Researchers from the University of California Los Angeles (UCLA) and CALeDNA have developed a toolkit designed to quickly identify the species in a biological community by simultaneously analyzing the environmental…
When collecting a DNA sample from a species in the wild just isn’t possible — it’s elusive, it may disturb the animal, or a host of other reasons — field…
Feeding aquatic sponges could provide biologists with unexpected underwater data collection assistance. Sponges (phylum Porifera) are immobile aquatic animals that eat by filtering out food particles from the water around…
Diego Cardeñosa wasn’t expecting any work calls on a Saturday, and certainly not one from the Hong Kong Customs and Excise Department. The urgency of the matter, however, became quickly…
Faster and cheaper Surveying and studying coral takes a lot of work. It’s usually done manually, which requires wet suits and air tanks and SCUBA gear and people. But it’s…
In 1995, there were only 51 kākāpō left on Earth, and it seemed that the giant flightless parrots were headed for extinction. Once abundant in New Zealand, the ground-dwelling kākāpō…
Remember that 3-meter (17-foot) pregnant Burmese python recently captured by wildlife authorities in southern Florida? These snakes, invasive to North America and destructive to native wildlife, are cryptic in both…
The waters of the eastern Baltic Sea around Finland are home to the flounder, a flatfish with both its eyes on one side of the head that uses its camouflage…
A multi-national research team has developed a rapid DNA identification method to help customs inspectors detect illegally traded wildlife products, beginning with sharks. The DNA testing protocol, published last month,…
Sharks shed bits of themselves into the ocean constantly. Scientists can now use DNA in these bits to monitor whether white sharks – commonly called great whites – are swimming…
A team at University of Texas Austin has developed a new method for identifying whether a mosquito is of the Aedes aegypti species, which is responsible for transmitting Zika, dengue and other deadly diseases. The…
In December 2015, officials from Nepal's Central Investigation Bureau had a hunch that something was amiss with the country’s tigers. The bureau, in the past few months, had seized more…
What do you call seaweed that grows in ponds? Pondweed, of course. This diverse group of freshwater plants provides food and shelter for freshwater fish, birds, invertebrates, and plankton. And…
Male elephants wander. As they mature and prepare to breed, they roam great distances in search of estrous females. These movements are key to elephant population dynamics: by breeding with…
When Colleen Kamoroff and her graduate advisor Caren Goldberg collected water samples to look for the DNA of non-native fish species, they could not have guessed the potential importance of…
