Ecology meets technology in a mechanized planet

It goes without saying that the world as we know it is becoming increasingly infused with technology. Besides the everyday devices—computers, cell phones, cameras, cars—huge advances are being made on a daily basis at the intersection of biology and technology. Areas like biorobotics, nanotechnology, geoengineering, genetically engineered organisms and global monitoring, for example, are gaining steam. In biorobotics, which also…

Q&A: Ecologists assess oil spill damage

An oil slick originating from a rig about 130 miles southeast of New Orleans, which is dumping oil into the Gulf of Mexico at a rate of approximately 25,000 barrels per day, is drifting toward the Alabama, Florida and Louisiana coasts, and scientists are still assessing the ecological impact that will result. In the Q&A below, three members of the Ecological Society of America’s Rapid Response Team discuss the current and possible future damage of this spill and the effects it could have on the Gulf region.

Invasive lionfish: from aquarium to dinner plate

The red lionfish (Pterois volitans) has decorated fish tanks, and invaded Atlantic waters, for decades. While sightings along the East Coast started popping up as early as the mid-1980s, lionfish began to spread rapidly, occupying reefs in the Florida Keys and the Bahamas in the 1990s. Since then, invasive red lionfish have been reported as far north as Rhode Island and, as of this January, tracked to the southern Gulf of Mexico off the Yucatan Peninsula.

The sharp shooters of marine life

The archerfish’s long distance spitting can fire a bug off of a branch and send it down to the water’s surface, and the nearly-blind pistol shrimp uses its gigantic claw to stun its prey with a bubble nearly as hot as the Sun. However, if the archerfish didn’t have keen eyes enabling it to detect an insect against a vegetative background, and if the pistol shrimp lacked its protective eye covers, called orbital hoods, these animals might never have developed the ballistic mechanisms that characterize them.

Field Talk: Termites enrich the soil in East Africa

Vertebrate fertilizer is not the only source of nutrients in the soils of East African savannahs, at least according to a study recently published in the journal Ecology. Alison Brody from the University of Vermont and colleagues found that termites actually had more of an effect on the fruiting success of Acacia trees in Kenya than did dung and urine deposition from ungulate herbivores, such as zebras and gazelles.

Climate change from a population perspective

Numerous policy discussions have emerged regarding the impact of climate change on humans; however, this interaction is a two-way street, said scientists in a Washington, DC briefing last Friday. That is, how will climate change impact human health and how will population growth affect factors like carbon emissions? The short answer is that they are closely connected; the longer answer is that scientists are currently trying to flesh out the exact effects and viable options for a future with global climate change, human expansion and urbanization.

Genome reveals olfactory communication in the zebra finch

In an article published earlier this week in Nature, researchers revealed the complete genome of the zebra finch and focused on the intricacies of their vocal communication. The zebra finch, the males of which are known to learn and repeat the same song generation after generation, show 800 active genes involved in vocalization. One group of researchers, however, found more…
