A global survey of biodiversity experts finds that more species are threatened with extinction than previously thought, with estimates suggesting 30% of species have been lost since 1500. The study identifies climate change, pollution, and land-use changes as key drivers of biodiversity loss.
A recent study by Xi'an Jiaotong-Liverpool University provides a method to help farmers and policymakers decide whether organic farming is beneficial for the environment. The researchers analyzed international studies to find a threshold where organic farming's biodiversity gain outweighs its land requirements.
A global study found that half of a tree species' distribution is in unprotected landscapes, with 13.6% having no protection at all. The researchers propose protecting 17% of land areas to safeguard tree diversity, covering 66-83% of their habitats.
A new study using sophisticated modelling and data from the Republic of Congo's marine national park found a steady increase in olive ridley turtle nests, while leatherback turtles' nesting numbers follow a cyclical pattern. The research highlights the region's importance for sea turtle conservation.
A recent study found that brightly colored, round-bodied fish are rated as the most beautiful by the public, while less attractive species tend to be more ecologically and evolutionarily distinct. These unattractive species, including those listed as threatened or in need of conservation evaluation, may receive less public support desp...
New research from the University of British Columbia creates the world's first global map of mammal movement between protected areas. The study reveals that Canada has critical areas for connectivity, which are essential for maintaining biodiversity and animal populations.
Researchers found that maintaining hard water reduces zinc accumulation and oxidative stress in goldfish, mitigating toxic effects. This study provides an eco-friendly approach to address aquatic ecosystem pollution caused by heavy metal contamination.
A study has discovered that humans are disrupting a fundamental pattern in ecosystems, which dates back at least 66 million years. The U-shaped relationship between diet and size in modern land mammals has been found to span across multiple vertebrate groups, including birds, reptiles, and fish.
Human activity on Hainan Island is causing changes in the body shapes and diets of tropical birds, resulting in biotic homogenisation. Despite efforts to protect biodiversity, the island's unique ecosystem is being affected by large-scale economic and land-use changes.
A study by the University of Queensland found that strong demand for tropical sea cucumbers as a delicacy is putting these species at risk of extinction. The research highlights the need for regulatory changes to protect the remaining populations and maintain healthy ocean ecosystems.
A study of 118 conservation units in Brazil found that 60% use unsuitable methods to detect deer presence. Visual analysis of droppings, fur, and footprints is a reliable method for most species, but others require DNA testing or camera traps.
A new method developed by researchers predicts the optimal time to spend learning about a species' habitat before designating protected areas. This balance between knowledge acquisition and resource allocation can save species from extinction while minimizing unnecessary protection of incorrect habitats.
The 2020 wildfires in Brazil's Pantanal wetland resulted in the deaths of an estimated 16.9 million vertebrates, including lizards, birds, and primates. The study estimates that between 13.2 million and 18.8 million small vertebrates and 691,000 to 1.2 million medium-to-large vertebrates were killed.
A new study found that female bushbabies experience sharper increases in glucocorticoid hormones than males, indicating they may be under more stress and have less wiggle room to survive in a changing environment.
A study quantifying Nigeria-linked seizures of pangolin products suggests levels of trafficking are far greater than previously thought. Researchers found 190,407 kilos of scales taken from at least 799,343 animals, with 77 seizures analysed revealing connections to ivory-smuggling networks.
A study found that large herbivore biomass is only present in African reserves, with a close correlation between plant productivity and consumer biomass. In contrast, non-African ecosystems have low herbivore densities, even in protected areas.
A new study published in Scientific Reports found that respiratory diseases can spread rapidly within wild mountain gorilla groups but are less likely to spread between neighboring groups. The study suggests that strategies preventing initial transmission into a group may be most effective in limiting disease spread.
Research suggests that concentrate farming allows for more natural habitats while meeting future food targets, resulting in better biodiversity outcomes compared to wildlife-friendly agriculture. This approach also sequesters more carbon and may benefit marine life.
Researchers sequenced genomes of 90 Eastern massasauga rattlesnakes and found that potentially damaging gene mutations were less abundant. This suggests that inbreeding might not be as detrimental as theory predicts, as beneficial mutations can easily purge bad ones. The study's findings could influence management decisions.
Researchers have mapped out the extent of habitat loss for salmon in the Lower Fraser River, revealing that up to 85% of historical floodplain habitat has been lost due to infrastructure. The study found that over 1,200 barriers block access to approximately 2,224 kilometers of streams, a major contributor to current salmon declines.
A study suggests that 96% of US crop wild relatives require high conservation priority due to limited understanding of their geographic distribution and current conservation status. Conservation action is needed in taxonomic hotspots across the country to safeguard these genetic resources for breeding and food security.
Researchers from the University of Tsukuba discover that old grasslands have higher plant diversity than new ones, and that grassland longevity can indicate high conservation priority. This finding suggests that focusing conservation efforts on long-standing grasslands will be most effective in preserving biodiversity.
Researchers have identified six threatened tenrec species out of 31, categorized as Vulnerable or Endangered due to habitat loss and hunting. The conservation status of tenrecs is expected to improve by integrating research into broader sustainable development objectives.
A new study published in Proceedings of the National Academy of Sciences reveals that most of the world's undiscovered species reside in regions already identified as conservation priorities. This suggests recent conservation efforts have been effective and should reduce uncertainty over global conservation priorities.
