Fish biodiversity protects coral reefs

Science Bulletins: Fish Biodiversity Protects Coral Reefs from AMNH on Vimeo. In tropical coral reefs, plant-eating fish and other herbivores support the dominance of the living coral by eating seaweed. Also known as macro algae, seaweeds create energy from sunlight through photosynthesis, like plants, and support much of the life in the sea. But they also compete with young corals for space, and with the photosynthesizing...

Before the colonial era, 100,000s of people lived on the land now called California, and many of their cultures manipulated fire to control the availability of plants they used for food, fuel, tools, and ritual. Contemporary tribes continue to use fire to maintain desired habitat and natural resources.

For bees (and flowers), tongue size matters

When it comes to bee tongues, length is proportional to the size of the bee, but heritage sets the proportion. Estimating this hard to measure trait helps scientists understand bee species’ resiliency to change. Ecologists will report on this and other pollination research news at the Ecological Society of America’s 2014 Annual Meeting in Sacramento, Cal., August 10-15.   For bees and the flowers they pollinate, a compatible...

Poo pump: whales as ecosystem engineers

The brown cloud bursts forth among the pod of sperm whales, dispersing a wealth of nitrogen and iron into the surface waters over the deep ocean. The whale-borne windfall is eagerly received by phytoplankton, the microorganisms at the foundation of the ocean food chain, which quickly capitalize on the surge of fuel. Poop packs a powerful energetic punch. And an adult sperm whale packs a lot of poo. Enough to dump 50 metric tons of...
