A recent study published in Conservation Biology found that threatened bird species tend to have their ranges overestimated by 40-70% compared to actual surveys. This overestimation is particularly pronounced for narrow-ranging and specialized species, which are also more vulnerable to extinction.
A landmark review evaluates six statistical methods to identify factors correlating with species distribution patterns and provides guidelines for their application. This work offers invaluable technical means to account for spatial dependencies in species distributions.
Researchers found that drought sensitivity is a key factor shaping tropical plant species distribution patterns, with denser plants on wetter sides and fewer on drier ones. This study provides new insights into the importance of water availability in shaping tropical forest ecosystems.
Researchers found that drought tolerance predicts plant distributions at local and regional scales in tropical forests. Drought-tolerant plants are more common in dry sites than in wet sites, even in humid forests.
A study by Conservation International finds that existing protected areas remain effective in the early stages of climate change, but adding new ones would maintain species protection in future decades and centuries. The research concludes that anticipating the need for new protected areas and getting them created in the short term wil...
A new study analyzing western hemlock distribution in North America's Pacific Coast and Rocky Mountains reveals that climate alone cannot explain species range. Spatial analysis suggests hemlock adapts better to drier summer conditions in the Rockies than coastal regions.
A recent DNA study has identified a single origin for domesticated potatoes, tracing them back to a broad area of southern Peru. This finding contradicts prior hypotheses of multiple origins and sheds new light on the evolutionary history of one of the world's most widely cultivated crops.
The National Invasive Species Council (NISC) partners with NASA to improve invasive species management. NASA provides Earth observations and predictive models to enhance partner abilities, improving accuracy and timeliness of predictive maps and plant species distribution forecasts.
Conservation efforts in Canada are threatened by growing human populations and economic development. Despite these challenges, conservation initiatives continue to focus on preserving biodiversity and ecosystem health.
Research by Jayanth Banavar, Igor Volkov, and Amos Maritan provides a mathematically stronger framework for Hubbell's Neutral Theory of Biodiversity, explaining patterns of relative species abundance and biogeography. The study rebuts criticisms and sheds light on the long-standing problem in island biogeography.
Researchers equipped Weddell seals with cameras and data recorders to track their movements and interactions with prey, gaining new insights into the habits of Antarctic silverfish and toothfish. The 'seal cam' technique sheds light on the behaviors of these little-known species, including migration patterns and depth ranges.
Scientists at Emory University create transgenic mice with a prairie vole vasopressin receptor gene, showing increased social behavior and adopting gregarious behaviors. The study provides an explanation for the species difference in receptor distribution and its impact on social behavior.
