- New research reveals remarkable resilience of sea life in the aftermath of mass extinctionson June 23, 2021 at 3:39 pm
Pioneering research has shown marine ecosystems can start working again, providing important functions for humans, after being wiped out much sooner than their return to peak biodiversity.
- Antelope's fate shrouded by social, political forceson June 22, 2021 at 7:43 pm
The story of efforts to conserve the endangered oribi in South Africa represent a diaspora of issues as varied as the people who live there.
- No northern escape route for Florida's coral reefson June 22, 2021 at 1:16 pm
Warming seas are driving many species of marine life to shift their geographic ranges out of the tropics to higher latitudes where the water is cooler. Florida's reefs will not be able to make that northward move, however, as they will be caught between intolerably hot tropical waters and increasingly frequent water-cooling cold snaps, according to new findings.
- Ancient bones provide clues about Kangaroo Island's past and futureon June 21, 2021 at 2:42 pm
A study of ancient bones on South Australia's Kangaroo Island has provided new information about the Island's past fauna and an insight into how species may live there in the future.
- Dragonflies: Species losses and gains in Germanyon June 18, 2021 at 5:40 pm
Over the past 35 years, there have been large shifts in the distributions of many dragonfly species in Germany. Those of standing water habitats have declined, probably due to loss of habitat. Running-water species and warm-adapted species have benefited from improved water quality and warmer temperatures. The study highlights the importance of citizen science and natural history societies for long-term data collection.
- Excess nitrogen puts butterflies at riskon June 17, 2021 at 5:38 pm
Nitrogen from agriculture, vehicle emissions and industry is endangering butterflies in Switzerland. The element is deposited in the soil via the air and has an impact on vegetation -- to the detriment of the butterflies, as researchers have discovered.
- Social secrets of killer whales discovered using droneson June 16, 2021 at 11:15 pm
Killer whales have complex social structures including close 'friendships', according to a new study that used drones to film the animals.
- Bycatch risk for dolphins and porpoises in global small-scale fisherieson June 15, 2021 at 5:21 pm
Marine scientists assessed the risk posed by small-scale fisheries to all 72 species of toothed whales found throughout the world's oceans. They found that this risk was highest in the Central Indo-Pacific, Temperate Northern Pacific, Temperate South America and the Western Indo-Pacific.
- New survey method proves Rhode Island's rarest frog may not be so rareon June 14, 2021 at 10:56 pm
A study by researchers using a seldom-used methodology turned up many more Eastern spadefoots, an endangered primitive frog, than they expected.
- Biodiversity 'hotspots' imperiled along California's streamson June 14, 2021 at 7:39 pm
A study of woodland ecosystems that provide habitat for rare, endangered species along streams, rivers throughout California reveals some ecologically important areas are inadvertently benefiting from water humans are diverting for their own needs. Though it seems a short-term boon to these ecosystems, the artificial supply creates an unintended dependence on its bounty, threatens the long-term survival of natural communities and spotlights the need for changes in the way water is managed across the state.
- Butterflies and moths have difficulty adjusting to a rapidly changing climateon June 10, 2021 at 8:24 pm
Climate change exerts great pressure for change on species and biodiversity. A recent study indicates that the few moth and butterfly species (Lepidoptera) capable of adjusting to a changing climate by advancing their flight period and moving further north have fared the best in Finland. In contrast, roughly 40% of Lepidoptera species have not been able to respond in either way, seeing their populations decline.
- Endangered blue whales recorded off southwest coast of Indiaon June 10, 2021 at 1:11 pm
Underwater recordings show that endangered blue whales are present and singing off the southwest coast of India. This extends the range of a known song type by 1,000 kilometers, into Indian waters. The results suggest that conservation measures should include this region.
- Hope for critically endangered gorillas in eastern DRCon June 9, 2021 at 3:55 pm
A new study has updated the global population estimate for the Critically Endangered Grauer's gorillas (Gorilla beringei graueri) -- the world's largest gorilla subspecies -- to 6,800 individuals from a previous global estimate of 3,800 individuals.
- African great apes to suffer massive range loss in next 30 yearson June 7, 2021 at 8:10 pm
A new study predicts massive range declines of Africa's great apes -- gorillas, chimpanzees and bonobos -- due to the impacts of climate change, land-use changes and human population growth.
- Black bears may play important role in protecting gray foxon June 3, 2021 at 9:12 pm
Bears are known for being devoted and protective of their baby cubs, but research shows that they may also play a significant role in shielding gray fox from predators like coyotes, who compete with the fox for food and space. The research is one of the first studies to show how black bears provide a buffer to allow other, smaller carnivores to safely co-exist.
- New technology 'listens' for endangered right whaleson June 3, 2021 at 9:11 pm
Researchers have developed technology that will help to protect North American right whales, one of the world's most endangered marine species. The new techniques can remove unwanted noises from recordings, thereby increasing the reliability of detecting right whales before they reach close proximity to large vessels. This can both protect animals and avoid costly shutdowns of offshore operations.
- How an elephant's trunk manipulates air to eat and drinkon June 1, 2021 at 11:41 pm
New research finds that elephants dilate their nostrils in order to create more space in their trunks, allowing them to store up to nine liters of water. They can also suck up three liters per second -- a speed 50 times faster than a human sneeze. The findings could inspire different ways to building robots that manipulate air to move or hold things.
- How best to focus efforts on classifying new species to prevent their extinction?on June 1, 2021 at 7:20 pm
Many organisms in need of conservation are still unknown or lumped in with similar species, which potentially interferes with conservation efforts. Researchers present a new 'return-on-investment' approach to best direct efforts to identify new species before they are lost.
- Adaptability of 158 butterfly species to urbanizationon June 1, 2021 at 2:06 pm
Expanding urban habitats are likely to endanger a large number of butterfly species in the long term. Generalists that tolerate large temperature fluctuations and feed on different plants are most likely to benefit from human-modified habitats. In order to preserve biodiversity, urban and spatial planning should take the needs of specialized butterfly species into account, the authors recommend.
- Plastic in Galapagos seawater, beaches and animalson May 28, 2021 at 12:53 pm
Plastic pollution has been found in seawater, on beaches and inside marine animals at the Galapagos Islands.
