A University of British Columbia evolutionary biologist shows that adaptation to the environment speeds up speciation. By displacing eco-types from their host plants and protecting others, Nosil found color pattern alone can initiate speciation, while additional traits like detoxifying chemicals are needed for completion.
The study found that an intermediate rate of dispersal creates a 'happy medium' wherein species move around enough to adapt to harsh environments, increasing ecosystem productivity and biodiversity. This breakthrough helps ecologists develop strategies for conservation areas with high biomass and diversity.
Cities face significant sustainability challenges, but urban ecologists can help by applying ecological principles to design and develop projects. By integrating biodiversity and ecosystem function into urban planning, researchers aim to create sustainable environments that support human well-being.
Researchers propose that pika leptin's adaptive functional evolution may be driven by cold environmental stress, not hypoxia. This discovery has significant implications for understanding small mammals' adaptation to extreme environments and identifying new candidate therapies for human diseases like obesity and diabetes.
A UC Riverside study shows that killing prey has both direct and indirect effects on ecosystems, leading to evolutionary changes in prey populations. The research found that prey adapt to food availability as well as the presence of predators, resulting in more food available to survivors.
Researchers analyzed E. coli adaptation in germ-free mice, finding rapid selection of bacteria carrying mutations in a master regulator controlling over 100 target genes. This suggests global regulators coordinate physiological activities necessary for adaptation to complex environments.
A UCLA summit published in Molecular Ecology highlights the need for additional research on human-caused ecological changes. The study reveals that climate change is outpacing species' ability to adapt, leading to increased disease threats, reduced biodiversity and loss of natural heritage.
A University of Virginia study shows that plant offspring from maternal plants in the same environment outperform those raised differently, indicating a temporary mechanism of adaptation to local conditions. The findings highlight the significance of maternal effects in plant biology.
A 10% increase in urban green space could reduce surface temperatures by as much as 4°C, effectively 'climate proofing' cities. However, this may not significantly impact the amount of rainwater captured and retained by urban areas.
New research suggests that insect species adapted to warmer climates have faster population growth rates, which could profoundly alter entire ecosystems. This adaptation is not limited to a few species, but can impact many insects, leading to changes in food webs and species diversity.
A study provides empirical support for natural selection's role in species formation by analyzing the relationship between adaptation and reproductive isolation in hundreds of organisms. The researchers found a positive link between these two processes, suggesting that adaptation drives species diversification.
The NSF announces six FIBR awards to tackle some of biology's most challenging questions. The projects will study the relationship between an organism's genes and the outside world, as well as animal movement, social behavior, and photosynthesis.
Researchers from Scripps Institution of Oceanography have sequenced the genomes of Synechococcus and Prochlorococcus, tiny organisms that account for up to two-thirds of carbon dioxide fixation in the oceans. The discoveries shed light on how these organisms process carbon and adapt to specific habitats, offering insights into global c...
Researchers found that North American red squirrels are adapting to warmer temperatures by advancing their breeding cycle by 18 days over 10 years. The team used quantitative genetics to separate individual plasticity from genetic adaptation, revealing a long-term trend of phenotypic plasticity.
A preliminary study at the University of Toronto found that green roofs were better at protecting roof membranes from extreme temperatures than conventional roofs. Green roofs also reduced storm water run-off and kept summer temperatures inside structures lower due to vegetation cooling effect.
Researchers found genes tailored to specific environments, shared among organisms living in the same ecological niche. The discovery could help understand how cells adapt to extreme conditions.
Ranchers are adapting to environmental changes by incorporating conservation techniques, such as managing grazing patterns and using native species. The symposium showcases successful examples of progressive management, including the use of beavers to restore woodlands and improve biodiversity.
Biologists at Cornell University and Max Planck Institute found that Daphnia crustaceans can evolve quickly to cope with polluted water. The study showed that these tiny crustaceans adapted to handle less nutritious food, becoming a natural control for toxic cyanobacteria in Lake Constance.
