What is an endangered species?
on January 17, 2020 at 9:27 pm
What makes for an endangered species classification isn't always obvious.
Human ancestors started biodiversity decline millions of years ago
on January 17, 2020 at 3:47 pm
The human-caused biodiversity decline started much earlier than researchers used to believe. According to a new study the process was not started by our own species but by some of our ancestors.
Mobile protected areas needed to protect biodiversity in the high seas
on January 16, 2020 at 7:17 pm
As the United Nations rewrites the laws of the high seas, the new document should anticipate emerging technologies that allow protected areas to move as animals migrate or adapt to climate change.
Newly created embryo nourishes hope for the survival of the northern white rhino
on January 15, 2020 at 5:06 pm
In December 2019 the team of scientists and conservationists repeated the egg collection from the northern white rhinos in Kenya and was able to create a new embryo over Christmas.
Humanity's footprint is squashing world's wildlife
on January 13, 2020 at 7:19 pm
Using the most comprehensive dataset on the 'human footprint,' which maps the accumulated impact of human activities on the land's surface, researchers found intense human pressures across the range of a staggering 20,529 terrestrial vertebrate species.
Deforestation is changing animal communication
on January 9, 2020 at 2:08 pm
Deforestation is changing the way monkeys communicate in their natural habitat, according to a new study. This study offers the first evidence in animal communication scholarship of differences in vocal behaviors in response to different types of forest edge areas.
Fish species benefit from marine protection to varying extents
on January 8, 2020 at 6:16 pm
Marine protected areas reduce fish mortality by limiting harvesting and reducing habitat destruction. They are often designed and implemented to promote biodiversity conservation and sustainable fisheries. New research shows these conservation efforts lead not only to an increase in the total number of fishes (individuals) in general. Protected areas in the northern Mediterranean Sea also harbor a higher number of common fish species, and significant positive network effects accumulate between individual reserves.
New 'umbrella' species would massively improve conservation
on January 7, 2020 at 3:49 pm
The protection of Australia's threatened species could be improved by a factor of seven, if more efficient 'umbrella' species were prioritized for protection, according to new research.
Climate change and deforestation could decimate Madagascar's rainforest habitat by 2070
on January 2, 2020 at 7:34 pm
A study has found that, left unchecked, the combined effects of deforestation and human-induced climate change could eliminate Madagascar's entire eastern rainforest habitat by 2070, impacting thousands of plants, mammals, reptiles, and amphibians that are endemic to the island nation.
Climate change not the only threat to vulnerable species, habitat matters
on December 23, 2019 at 5:28 pm
Though climate change is becoming one of the greatest threats to the Earth's already stressed ecosystems, it may not be the most severe threat today for all species, say authors of a new report on the effects of deforestation on two lemur species in Madagascar.
Where do baby sea turtles go? New research technique may provide answers
on December 23, 2019 at 5:28 pm
A team of researchers created a first-of-its-kind computer model that tracks where sea turtle hatchlings go after they leave Florida's shores, giving scientists a new tool to figure out where young turtles spend their 'lost years.'
Biodiversity has substantially changed in one of the largest Mediterranean wetlands
on December 19, 2019 at 7:28 pm
The Camargue area in France has considerably fewer grasshopper, cricket, locust, dragonfly, and amphibian species than 40 years ago. On the other hand, there are more birds and vascular plants, some of them considered as new and highly invasive species.
Amazon forest regrowth much slower than previously thought
on December 19, 2019 at 5:25 pm
The regrowth of Amazonian forests following deforestation can happen much slower than previously thought, a new study shows. The findings could have significant impacts for climate change predictions as the ability of secondary forests to soak up carbon from the atmosphere may have been over-estimated. The study, which monitored forest regrowth over two decades, shows that climate change, and the wider loss of forests, could be hampering regrowth in the Amazon.
Human management helps rare plants, butterflies survive hurricane
on December 18, 2019 at 8:34 pm
Ongoing habitat management could help prevent hurricane-driven extinctions. A rare Florida plant, the pineland croton, weathered the damage from Hurricane Irma better in plots that were under human management than those left alone.
Even resilient common species are not immune to environmental crisis
on December 18, 2019 at 2:02 pm
Researchers have found that the effective population size and genetic diversity of Singapore's Cynopterus brachyotis, believed to remain widely unaffected by urbanization, has shrunk significantly over the last 90 years - revealing that the current biodiversity crisis may be much broader than widely assumed, affecting even species thought to be common and tolerant of fragmentation and habitat loss.
Consider marine life when implementing offshore renewable power
on December 17, 2019 at 4:42 pm
With countries adopting green energy practices, renewable energy now accounts for a third of the world's power. As this trend continues, more countries are looking to offshore energy sources to produce this renewable energy. Researchers identify situations where green technology such as wind turbines, wave energy converters, and other marine renewable energy devices (MREDs) have had negative consequences on marine life.
New 'netherworldly' freshwater fish named for Thai conservation visionary
on December 16, 2019 at 5:24 pm
Garra surinbinnani looks like a stout, brown minnow with the face of a boxer who's gone one too many rounds. The species makes its home in the fast-flowing, rocky streams of Western Thailand, a region that its namesake, the late conservationist Surin Binnan, devoted himself to protecting.
Southern white rhinos are threatened by incest and habitat fragmentation
on December 16, 2019 at 4:01 pm
The fragmentation of natural habitats by fences and human settlements is threatening the survival of the white rhinoceros. It prevents dispersal from the family group and leads to mating among close relatives. Additionally female rhinoceros favor individual males for mating over others and sire several offspring with the same partner over consecutive breeding periods. The results come from the largest scientific study to date on the sexual preferences of white rhinos.
Northern Ireland's recovering pine marten population benefits red squirrels
on December 13, 2019 at 1:07 pm
The recovery of pine marten in Ireland and Britain is reversing native red squirrel replacement by invasive grey squirrels, according to new research.
Managing shark populations in Pacific Panama
on December 11, 2019 at 4:56 pm
A study in Pacific Panama identifies 11 potential nursery areas of locally common and migratory sharks, which could support shark conservation efforts in the region.
