In India, vaccination, sterilization of stray dogs curbs rabies better than culls

When people encounter stray dogs in Jaipur, India, they cross the street to put distance between themselves and a potentially deadly bite. Street dogs are endemic in Indian cities and experience has taught citizens caution. The incidence of rabies in the stray population is uncomfortably high, resulting in about 20,000 human cases every year. Most cities have tried to solve…

Rim Fire, California 2013. Mike McMillan, USFS.

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…

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…

A lovely Augochlora pura extends part of its tongue. A. pura is a member of the relatively short-tongued Halictidae family, uprettily known as the sweat bees. The small, solitary bee is one of the most common bees of forests and forest edges in the eastern United States, and a promiscuous attendant to many flower species. Collected by Phillip Moore in Polk County, Tennessee. Photograph by Phillip Moore. Photo courtesy of the USGS Bee Inventory and Monitoring Lab.

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…

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…

Tadpoles bulk up to meet the alien invaders

What happens when an invasive, carapaced, and clawed, alien predator arrives in your pond? Do you change your daily habits to avoid drawing dangerous attention? Bulk up to make yourself a tougher target? If you an Iberian water frog, you do both.

Butcher, baker, and brewer. This image illustrates the strikingly simple but powerful analogy between man-made and natural systems. By looking at the functional structure of coral reef fish communities through a human eye, we find butchers, bakers, and brewers, but also diligent, cranky farmerfish, visually pleasing but ecologically negligible aesthetes, or worthless aristocrats. Using this approach, we can begin to answer some of the most pressing questions in coral reef biology. What are the origins and future trajectories of coral reefs and their fishy inhabitants? How do humans affect this perfectly balanced market? And do more brewers really make a happier system? Simon J. Brandl.

Butcher, baker, brewer-fish

We asked science café aspirants for creativity and Simon Brandl brought it with his analogy of division of labor in a coral reef community, where butcher-sharks course among the brewers, bakers, and aristocrats of the reef. Brandl shares the 2014 ESA Science Café Prize with co-winner Madhusudan Katti. He is a PhD candidate at the ARC Centre of Excellence for…

These are not your urban lawn flamingos! This pair dancing in the low tide in Mumbai’s busy harbor are Lesser Flamingos, considered near-threatened species due to declining populations in Africa and India. Yet, over the past decade, some 10-25 thousand of them have been turning up in Mumbai’s Thane Creek to spend the winter right in the middle of a megacity of over 20 million people. I photographed this pair just a year ago at Sewri Port, an industrial dockyard area known more for repairing boats than harboring such wildlife which now teems in the creek’s recovering mangroves.

These are not your urban lawn flamingos!

Madhusudan Katti won this year’s ESA Science Café Prize with his lyric contemplation of the wildlife living alongside us in urban spaces, and the necessary participation of cities in the future of biodiversity on planet earth. Katti is a professor at California State University Fresno and records occasional radio essays for Valley Public Radio. He tweets prolifically as @leafwarbler and…
