History of fire and drought shapes the ecology of California, past and future

Fire season has arrived in California with vengeance in this third year of extended drought for the state. A series of large fires east of Redding and Fresno, in Yosemite, and on the Oregon border prompted Gov. Jerry Brown to declare a state of emergency on Sunday, August 3rd. As force of destruction and renewal, fire has a long and intimate history with the ecology of California. Ecological scientists will discuss aspects of that...

The Rim Fire one year later: a natural experiment in fire ecology and management

The enormous conflagration known as the Rim Fire was in full fury, raging swiftly from crown to crown among mature trees, when it entered the backcountry of Yosemite National Park in California’s Sierra Nevada in late August 2013. But inside the park, the battle began to turn, enacting a case study in the way management decisions and drought can combine to fuel large, severe fires.

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...

Pikas act as ‘climate indicators’

The Oscar-winning Disney movie “Frozen” includes a living snowman character named Olaf that would melt and die under the 70 degree temperatures humans and many other animals prefer. Of course, there are a number of species in the animal kingdom sensitive to heat conditions humans generally find preferable. Some of these are fellow mammals , but not all, are limited to the extreme cold Arctic and Antarctic climates. At home in loose...

The control of nature: stewardship of fire ecology by native Californian cultures

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...
