A new CU-Boulder study assesses 69 historical sites in the Southern Rockies and finds that 65 of them are still occupied by pikas, contrasting with a recent Great Basin study showing local extinctions increasing five-fold. The team found that drier conditions at abandoned sites may be driving pika disappearance.
A new study combining short-term and long-term data found that rapid evolution does not always persist, and major changes tend to take around 1 million years to occur. The research supports the concept of 'punctuated equilibrium' and suggests that natural selection forces must be widespread for changes to accumulate.
Conservationists may better protect mammal populations by treating their ranges as multiple interacting small populations. This approach considers local environmental factors that influence animal resiliency and can provide a more accurate picture of how species' ranges collapse due to human encroachment.
Researchers found that local populations of Joshua trees and their pollinating moths are not as biologically diverse as expected, contradicting previous theories. The study suggests that co-evolution between the species can actually decrease diversity within each species.
A new study found that the US adult obesity burden has significantly increased since 1993, with quality-adjusted life years (QALYs) lost due to morbidity and mortality from obesity more than doubling. The prevalence of obesity for US adults rose from 14.1% to 26.7%, and obesity-related QALYs lost followed a similar pattern.
A recent study by Queen's University Belfast found that hares are eighteen times more abundant in areas managed by the Irish Coursing Club than similar sites in the wider countryside. This suggests that active population management positively increases hare abundance.
A recent study found that introducing new genes from distant populations to damaged ecosystems can have negative consequences on native populations. However, the introduction of genes from nearby, contrasting environments can lead to poorer seedling performance and reduced fitness over time.
