Researchers from the University of Washington and US agencies propose strategies for sustainable subsistence hunting, reducing crowding and ensuring ecological space. They emphasize the importance of monitoring subpopulations regularly and adjusting harvests accordingly to mitigate negative effects of habitat loss.
A recent study found that habitat destruction has far surpassed habitat protection globally, with nearly half of the world's ecoregions classified as 'very high risk'. This loss has been particularly pronounced in Europe, South Asia, and North America, with many species facing extinction due to human activity.
Researchers report that over half the planet has been converted to human-dominated land use, with alarming levels of habitat loss persisting. The study highlights the need for targeted conservation interventions in crisis and at-risk ecoregions where habitats are disappearing.
A study published in Nature Communications suggests that timely conservation action can slow extinction rates and save species. The research found similar patterns of species loss following habitat disruption across various taxonomic groups, including birds, mammals, plants, reptiles, and invertebrates.
An international team has compiled the largest library of bat sounds, allowing researchers to accurately identify and differentiate between 59 bat species found in Mexico. The developed method can be used to monitor biodiversity change and characterise bat communities in different regions.
New research highlights uncertainty in global biodiversity data due to species sighting recording methods. Recording absences is crucial for effective conservation prioritization, as lack of data doesn't necessarily mean a species is absent.
Paul West will discuss how global and regional data sets can be used to enhance productivity while considering climate change and environmental impact on subsistence farmers. The talk aims to provide insights into the opportunities and risks related to improving food security and sustainability in data-limited areas.
The study reveals that Grey Parrot populations have declined by 90-99% since 1992, threatening their survival. Habitat loss and poaching are major drivers of this catastrophic decline, highlighting the urgent need for conservation efforts.
A new study highlights huge gaps in the conservation of migratory birds, particularly across China, India, and parts of Africa and South America. More than half of migratory bird species have suffered serious population declines over the past 30 years.
Research reveals a significantly larger-than-estimated chimpanzee population in Uganda's fragmented habitats, with populations of up to 319 individuals found across 633 km2. The study suggests that chimpanzees' adaptability and behavioral flexibility enable them to survive in degraded environments.
A study has found that habitat loss and fragmentation are major threats to the world's felid species, including the critically endangered Iberian lynx. The lack of research and financing hinders effective conservation strategies.
A recent survey in Beijing shows public inclination towards banning tiger products and supporting conservation breeding over farming. The study highlights the need to maintain suitable population sizes and handle dead individuals during breeding.
Young corals and fish are repelled by the smell of damaged reefs, discouraging them from settling in degraded habitats. Marine protected areas may not be sufficient to promote reef recovery as chemical cues continue to drive away new fish and coral long after overfishing has stopped.
A major study analyzing all penguin species highlights the need to mitigate effects of habitat degradation, food scarcity, and climate change. The authors recommend measures such as establishing marine protected areas and implementing ecosystem-based management methods to protect biodiversity.
A new study reveals that juvenile steelhead trout are more likely to die when water levels are low in California's wine country. The researchers found that the amount of vineyard acreage upstream is linked to higher death rates, with only 30% survival rate in dry summer seasons.
A decline of 60% in marten detection rates in California's Sierra Nevada mountains may be attributed to habitat fragmentation and loss due to logging. The study suggests preserving marten habitat, which benefits other species thriving in old forests at high elevations.
Researchers developed a predictive model to identify areas at high risk of wetland habitat loss in the southern United States. The study highlights the importance of conservation efforts in these regions, where urbanization and development have led to significant wetland losses.
A comprehensive assessment of the world's mammals reveals that 25-36% of species are threatened with extinction, with habitat loss and overexploitation being major drivers. The study highlights the urgent need for conservation efforts to prevent further species losses and protect biodiversity.
The American Society for Horticultural Science reports that Borneo is home to 2500-3000 orchid species, but many are endangered due to habitat destruction and over-exploitation. A recent study has identified 197 species of orchids in West Borneo, highlighting the need for conservation efforts to protect these rare species.
Researchers warn of a 'biodiversity tragedy in progress' due to tropical habitat loss, with up to 15 million hectares lost annually. The review calls for an immediate, multi-pronged approach to conserve ecosystems and mitigate human impacts.
A study in Ecological Applications finds that cluster development reduces habitat loss, but the placement of housing developments around sensitive areas like lakeshores can exacerbate environmental effects. The researchers suggest that clusters must be located away from these areas to reduce impacts.
A new study by Samantha Price finds that large grazing animals face a higher risk of extinction under intense hunting pressure. The analysis reveals that reproductive speed is the key variable in determining extinction risk, with species like the American bison being nearly wiped out due to slow reproductive cycles.
A new study found that the simultaneous effect of habitat fragmentation, overexploitation, and climate warming accelerates population decline and increases the risk of extinction. Experimental microcosm populations of rotifers showed significant declines under individual threats, but even faster declines when exposed to multiple threats.
A K-State professor developed a landscape-based model to assess extinction risk for migratory songbirds affected by habitat loss and fragmentation. The study found that the rate of habitat destruction, rather than its extent, may be crucial in determining extinction risk.
Researchers at Emory University found that infected monarch butterflies flew slower, were tired faster, and had reduced flight ability compared to healthy ones. The study suggests parasite burdens are lower in migratory populations, which may have implications for conservation efforts.
Temperate grasslands like the Great Plains suffer from inadequate land protection, with species-rich ecosystems and habitats for imperiled species at risk. Temperate conifer forests in regions like the Northwest U.S. exhibit robust conservation efforts, even amidst relatively low levels of development.
A novel method integrates habitat modelling and spatial population dynamics in reserve-network design to consider the impact of habitat loss on species survival. This approach represents a step towards more realistic consideration of species survival when selecting reserve networks.
A new study reveals that plant extinction rates are significantly higher than previously thought, with California playing a significant role. The researchers used data on native plant species in California to find that contiguous human development can lead to the loss of entire species.
