Sharks, Spines and Speed
15+ hour, 28+ min ago (62+ words) (IMAGE) EurekAlert! By examining the vertebrae of six shark species, researchers discovered that the spine is far more than a flexible support column. It’s a finely engineered biomechanical system designed to maximize strength, flexibility and swimming efficiency. Credit: Florida Atlantic…...

Cutting out the noise: How horseshoe bats adapt their echolocation behavior in colonies
3+ day, 12+ hour ago (299+ words) Greater Japanese horseshoe bats modify the frequency of their constant-frequency (CF) echolocation calls when mixed with a population with a different CF until both frequencies converge, new study finds. Lower-frequency bats make larger shifts in frequency than higher-frequency individuals. The…...

Stability across plants, herbivores and predators is most closely associated with varied herbivore species dominance (asynchrony) in an arid grassland ecosystem.
4+ day, 11+ hour ago (176+ words) The horizontal bars indicate the standardized effect, direct (solid) or indirect (transparent), of different variables in a model grassland ecosystem. Our study demonstrates that herbivores, the intermediate consumer trophic level between predators and plants, are a key source of buffering…...

Herbivore species dynamics is key to grassland food web stability
4+ day, 12+ hour ago (240+ words) Researchers investigate factors that drive ecosystem stability at multiple, rather than a single, level of the food chain. Ecologists have long understood that biodiversity is paramount to the stability of ecosystems. Until now, however, the majority of ecological research has…...
