Ecologists have developed a new framework for understanding relationships among animals, plants, and their environments, enabling predictions about species' reactions to changing climates. The periodic table of ecological niches, built from decades of fieldwork data, reveals convergent evolution in lizards across continents.
Research finds that human activities such as urbanization and forest fragmentation alter fruit bat habitats, increasing the risk of Hendra virus transmission to humans. The study highlights the importance of preserving ecosystem integrity and habitat suitability to mitigate this risk.
Researchers at International Institute for Applied Systems Analysis developed a model that elucidates the natural patterns of biodiversity in tropical forests. The study shows how physiological differences and competition for light lead to a large number of species coexisting, challenging traditional ecological theory.
Researchers found that bird species with increasing populations occupy a broader range of climate conditions, while declining species lose their range. This discovery has practical applications for conservation biologists, who can use the new findings to develop more accurate habitat protection strategies.
A new lizard species, Anolis landestoyi, has been found in the Dominican Republic, revealing similar evolution on separate Caribbean islands. The discovery adds support to the concept of replicated adaptive radiation in anoles.
Researchers at University of Waterloo developed a new statistical tool, nicheROVER, to analyze multiple ecological niche parameters and identify overlap between species. This allows for more informed predictions about the impact of invasive species on native ecosystems.
Researchers found that filling of ecological niches slows the diversification of Himalayan songbirds. The study, which analyzed genetic relationships between 461 songbird species, discovered that eastern Himalayan species are separated from each other by six to seven million years, suggesting a slowing of evolution.
A Cornell professor's new research in Science has found evidence of more complexity in the relationship between flies and their predators, the parasitic wasps. The study revealed that most wasp species are extreme specialists, with offspring only able to survive in one specific fly species.
A study found that statistical tests using geographic distribution models can incorrectly infer changes in environmental requirements. The models often accurately identify similar environments but struggle with drastically different ones.
A study of 140 European mammals found that climate niches differ significantly even among closely related species, indicating fast adaptation to changing conditions. Competition between species is the key factor in shaping their distribution, rather than predicted climate change.
A new method by MIT researchers distinguishes between large groups of microbes based on their ecological niches. By analyzing genetic data and habitat preferences, scientists can now classify microbes with greater accuracy.
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.
