Research reveals that lone male black bears are the primary cause of fatal attacks on humans, with a significant increase in attacks linked to human population growth. The study also found that familiarization with humans and previous bear encounters do not necessarily lead to increased attack rates.
Dr. Kenneth F. Raffa, a renowned expert in forest entomology, has been selected to deliver the Founders' Memorial Award lecture at Entomology 2010. He will honor the memory of Dr. Andrew Delmar Hopkins, considered the father of North American forest entomology.
A new study reveals that female jumping spiders fight with different rules than males, skipping preliminaries and engaging in all-out battles. The researchers found that the motivation behind a female's fighting behavior is her proximity to reproductive age and desire to protect her nest.
Professor Hanna Kokko has been awarded the Per Brinck Oikos Award 2010 for her groundbreaking research on ecological and evolutionary dynamics. Her work focuses on the interactions between individual behavior, life-history theory, and population dynamics, with applications to conservation and management problems.
A new study reveals that chimpanzees infected with SIV, the precursor to HIV-1, contract and die from AIDS. Infected females were less likely to give birth, and infants born to infected mothers were unlikely to survive. The virus was transmitted sexually and through mother's milk.
A large-scale analysis of over 80 terrestrial carnivore species in the Americas shows that avoidance strategies have driven their evolution. The study found that some species use coloration to warn predators, while others occupy different habitats or are active at different times.
According to UCLA behavioral ecologist Daniel T. Blumstein, biology and evolution offer valuable lessons on managing security threats. By studying species' risk management strategies, we can learn how to allocate energy to defense versus other things, and how not to overreact.
Researchers used Palm Pilots as electronic diaries to analyze mood variability in BPD patients, finding significant instability in positive and negative moods. The devices helped bridge the communication gap between therapists and patients.
A Texas A&M University anthropologist has discovered a group of long-lost primates, the pygmy tarsiers, in Indonesia. The creatures, weighing less than 2 ounces, possess distinctive features such as claws instead of nails.
Research reveals that different wildtype Drosophila species respond selectively to natural odors like bananas and mangos, but not artificial flavors. The behavior is influenced by nutritional conditions and genetic adaptations to environment.
A new study from Tel Aviv University finds that people's response to risk is driven by personal experience and simple strategies for coping in nature, rather than logical rationales or statistics. This behavior may not be well-suited for the modern world, where risks are more complex and unpredictable.
The emerging field of neuroecology explores how neural mechanisms influence population dynamics and community interactions. Researchers discuss the ecological functions of chemical defenses, such as neurotoxins and inking, which have far-reaching consequences for ecosystems.
A study by researchers at the University of Bristol found that female woodhoopoes that started breeding later in life produced more offspring than those that started earlier. The researchers attributed this to a high mortality rate among young females, suggesting they were not yet in optimal condition to breed.
Researchers analyzed 24 years of data from a cooperative bird species, finding that delayed breeding was not costly to lifetime reproductive success for females. In contrast, males showed reduced reproductive success due to shorter breeding careers. The study challenges the long-held assumption that delayed breeding is always detrimental.
Research shows tadpoles respond more conservatively to predator cues during the day, but return to feeding quickly at night due to higher growth rate-to-predation risk ratio. This study highlights the importance of considering both external and internal factors in understanding prey behavior.
A study by Saskia van Vuren reveals that changes in the riverbed elevation can cause high-water problems, flooding, droughts, erosion, and affect discharge distribution. The researcher argues that future high-water level predictions must consider morphological dynamics.
In an experiment, male sand gobies were found to work harder at building nests and taking care of eggs when females were present, demonstrating 'courtship parental care'. Unaccompanied males were more likely to abandon their parental duties or even eat their own eggs.
Professor Bill Mitsch of Ohio State University has won the prestigious Stockholm Water Prize for his work on preserving and studying wetlands. The award recognizes his decades-long research on ecosystem behavior and his efforts to address water crises, including the annual hypoxia problem in the Gulf of Mexico.
