Choosing good mates and rearing thriving offspring are key to the species' long-term survival. https://phys.org/news/2023-08-monkey-poop-endangered-species.html Plants & Animals Thu, 03 Aug 2023 03:54:13 EDT news610253635 Sea urchins are struggling to 'get a grip' as climate change alters ecosystems When you are driving through a rain storm, traction is key. If your tires lack sufficient tread, your vehicle will slip and slide, and you won't have the grip needed to maneuver safely. When torrential rains hit near-shore, shallow water ecosystems, sea urchins experience a similar challenge. Heavy precipitation can alter the concentration of salt in the ocean waters, causing lower salinity levels. Even a slight change in salinity can affect the ability of sea urchins to securely attach their tube feet to their surroundings—like tires gripping the road. This becomes a matter of life and death for the small spiny creatures, as they rely on their adhesive structures to move in the wave-battered rocky area near the seashore. https://phys.org/news/2023-08-sea-urchins-struggling-climate-ecosystems.html Plants & Animals Ecology Wed, 02 Aug 2023 16:09:13 EDT news610211348 Substitution of tolerant for sensitive species balances ecosystems in agricultural areas, study says Contributing to the pursuit of sustainable farming, especially sugarcane growing, Brazilian researchers have shown that water bodies such as ponds and even puddles can maintain ecosystem services, provided there are tolerant animals in the vicinity to replace those most sensitive to agricultural practices. https://phys.org/news/2023-08-substitution-tolerant-sensitive-species-ecosystems.html Plants & Animals Ecology Wed, 02 Aug 2023 11:23:07 EDT news610194183 The heaviest animal ever may be this ancient whale found in the Peruvian desert There could be a new contender for heaviest animal to ever live.

According to a new study from the University of Florida, these tiny pests also pose problems for the iconic monarch butterfly. The study found that when oleander aphids infested tropical milkweed—a nonnative milkweed species commonly used across southern portions of the U.S. stretching from California to Florida—the butterflies laid fewer eggs on the plants, and caterpillars developing on those plants were slower to mature. https://phys.org/news/2023-07-aphids-tropical-milkweed-monarch-butterflies.html Plants & Animals Ecology Wed, 26 Jul 2023 14:00:02 EDT news609579716 Fast electrical signals mapped in plants with new bioelectronic technology What happens inside the carnivorous plant Venus Flytrap when it catches an insect?

It is well known that they use their long hydrophobic legs and support their bodies on the surface without breaking it. Under each leg, the water surface bends down creating a dimple (meniscus). Heavier water striders create deeper dimples, which produce stronger upward force from the downward stretched water surface that supports the insect body. https://phys.org/news/2023-07-world-largest-striders.html Plants & Animals Molecular & Computational biology Thu, 20 Jul 2023 15:32:12 EDT news609085922
