Risk of extinction accelerated due to interacting human threats

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.

The floral network -- what determines who pollinates whom

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.

Unweaving amyloid fibers to solve prion puzzles

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.

Traditional models underestimate extinction rates

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.

Sponges as drugs

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.

Examination of internal 'wiring' of yeast, worm, and fly reveals conserved circuits

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.

NYU researchers simulate molecular biological clock

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.

Is being big clam on the block a factor in species success?

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.

Diversity of species triumphs

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.
