Wing shape determines how far birds disperse

Researchers used flight efficiency estimates from museum specimens to predict bird dispersal distances, revealing that species with elongated wings can disperse farther. This study has applications in biodiversity conservation, as reduced flight capabilities may threaten bird populations.

Behavioral ecology: Environmental heterogeneity maintains personality in wild bird

Researchers found that certain personality types excel in specific countries and years due to environmental factors like predator presence and beechmast availability. This suggests that spatial and temporal variation in selection promotes the maintenance of behavioral differences within species.

Wild bees need deadwood in the forest

A recent study published in Forest Ecology and Management found that creating deadwood in coniferous forests can promote the abundance of aboveground nesting bees. The researchers created artificial structures with standing timber in six sample plots in the Black Forest National Park, leading to an increase in wild bee populations.

Hippos and anthrax

A team of researchers tracked the movements of hippos in Ruaha National Park, Tanzania, to better understand how anthrax outbreaks spread. They found that infected individuals roamed just as much as healthy hippos, highlighting the importance of wildlife movement in disease transmission.

Whale carcasses help answer mysteries of elusive species

Researchers analyzed stable isotope analysis of skin, muscle, and bone tissue to study Sowerby's beaked whale spatial ecology. The results show that the species exhibits both short- and long-term habitat fidelity, with at least two subpopulations in the eastern and western Atlantic.

How do humpback whales rest?

Researchers attached an omnidirectional camera to a humpback whale to study its resting behavior. The whale was found to be inactive for half the recorded period, with active behavior in the latter half, suggesting it may have been recovering from foraging.

Chemical signal in plants reduces growth processes in favor of defense

Researchers found that beta-cyclocitral produced by plants after herbivore attack increases defense responses and inhibits the production of metabolites for growth in Arabidopsis thaliana. This volatile signal opens up new possibilities for developing herbicides or antimicrobial agents that block the methylerythritol 4-phosphate pathway.

Lack of diversity in science

A study of 1051 top-authors found women and the Global South are starkly underrepresented, with only 11% female authors and 25% from the Global South. The research highlights a need to promote scientific diversity and inclusion in leadership recruitment and career development.

New study evaluates the advancement of ecology from a 2D to 3D science

A new study co-led by Arizona State University's Greg Asner explores the advancement of ecology from a 2D to a 3D science, leveraging remotely sensed 3D information to provide new ecological insights. The research has potential applications in addressing challenges associated with integrating dynamic oceanographic information and bette...

Biodiversity protects bee communities from disease

A new analysis of thousands of Michigan bees reveals that the most diverse bee communities have the lowest levels of three common viral pathogens. This study suggests that promoting diverse bee communities may be a win-win strategy to reduce viral infections in managed honeybee colonies while maintaining native bee biodiversity.
