A recent study published in Nature finds good agreement between species richness of tropical forests and coral reefs and a simple mathematical model based on the neutral theory of biodiversity. The researchers argue that interactions between species can be largely ignored, contradicting previous claims from other scientific teams.
Historical viral RNA sequences found in native and invasive grasses provide insights into the complex picture of species interactions and implications for modern agriculture. The study suggests that ancient viruses may have contributed to the takeover of California's native grasslands by invasive annual plants.
A recent study by a UT researcher found that hybrid salamanders are thriving in California water bodies, contradicting the general understanding of hybridization in animals. The hybrids, created by mating between two different species, show surprising vigor and may even enhance the chances for survival of the native species.
A new study found that the simultaneous effect of habitat fragmentation, overexploitation, and climate warming accelerates population decline and increases the risk of extinction. Experimental microcosm populations of rotifers showed significant declines under individual threats, but even faster declines when exposed to multiple threats.
A new study proposes that two key mechanisms, trait complementarity and barriers to exploitation, explain the structure of actual networks of plants and their pollinators. The models incorporating these mechanisms better mimic real networks, suggesting a balance between specialist and generalist interactions.
Scientists have found a way to analyze the configuration of amyloid fibers using yeast strains, providing insights into how prions interact with each other. The study reveals that prions have only two points of contact, known as the 'head' and 'tail,' which determine their interactions.
A new study reveals that traditional models of extinction underestimate species extinction risk by ignoring a critical parameter. The researchers used water fleas as a model organism and found that incorporating density-dependent demographic stochasticity into the models accurately predicted extinction rates.
Researchers found that sponges produce bioactive substances in response to competition, which is crucial for developing new drugs. However, the growth rates of cultivated species are slow and unpredictable, resulting in lower substance production compared to natural counterparts.
Wendy Saltzman's study finds that subordinate female monkeys are infertile until they become dominant, potentially benefiting them by reducing resource investment in infant survival. Her research on marmoset social behavior has implications for understanding human fertility and reproductive functioning.
Researchers compared yeast, worm, and fly proteins and found conserved communication pathways and protein clusters involved in essential cellular functions. The study supports the concept of a basic wiring diagram for all eukaryotic cells and may lead to more effective treatments with fewer side effects.
Researchers at NYU developed a mathematical model that replicates the complex network of molecular interactions within a cell's circadian clock. The study found that rapid binding and unbinding of regulatory molecules is crucial for accurate timekeeping, contradicting the notion that more molecules lead to better accuracy.
Research shows how individual species interact with each other after extinction, affecting recovery and evolution. Marine snails' feeding behavior changed from drilling holes to reach soft bodies inside clam shells.
The Delacour's langur is one of the most Critically Endangered primates in the world, with only 300 individuals remaining. Conservation efforts are underway to protect the species, but time is running out, and it may soon become extinct.
The study found that oil's negative effects last far longer than expected, with some species suffering long-term losses due to chronic exposure. The findings highlight the importance of controlling stormwater runoff and revising water quality standards to mitigate pollution.
Cattle introduction modifies frequent interactions between plants and pollinators, affecting web structure. This modification is likely important for ecosystem function.
A Virginia Tech research project suggests that body size may not be directly related to evolutionary or ecological success. Early findings indicate that diversity and body size increased together during the history of life, but this relationship broke down at the end of the Ordovician period, around 440 million years ago.
A new study confirms that global warming is affecting Earth's species worldwide, causing disruptions to animals and plants. The research found that even small changes in temperature have significant effects on ecosystems, leading to species migration, breeding, and population shifts.
Researcher David Tilman's study found that mixing multiple plant species leads to higher productivity, as each species brings unique traits for resource utilization. This principle can benefit various ecosystems, including forests and fisheries, by promoting a more diverse range of organisms.
A team of scientists from Texas A&M University has developed a mathematical model to better understand wildlife habitats and interactions. The model uses equations to describe how animals and plants live, grow, and interact with each other in different environments.
