The phrenologist’s guide to ecological competence

Since Darwin, scientists have been theorizing as to why there is variation in brain size between species and individuals. Does a larger brain, in say humans, indicate advanced cognitive abilities and complex language processing? Or is a smaller brain, such as the Olive-backed thrush’s, adapted to weigh less to accommodate lengthy flights?

In psychology, the field of phrenology has generally been dissolved, and with it, the idea that variations in brain size could indicate differences in intelligence, creativity or personality between humans. In the field of biology, however, scientists are discovering that brain variation across species might actually be linked to ecological competence. In this case, ecological competence describes the efficiency of a species to engage in ecological processes—such as flexible foraging abilities or advanced spatial memory for migration.

Rails-to-Trails, Bikes to Google

Using routes and maps from the Rails-to-Trails Conservancy’s (RTC) trail finder site, Google Maps now offers bicycle routes in its directions feature.  Simply type in your address, where you want to go and select “Bicycling” from the drop down menu. You should get at least two possible routes. Since 2000, RTC has gathered information on more than 1,600 rail-trails and connecting…

Scientists and filmmakers are making “Waves” together

Even though most of my face was covered by neoprene, acrylic glass and rubber, I could still feel the whiskers of the harbor seal rub against my skin as he repeatedly kissed my face. Believe it or not, the harbor seal wasn’t the only marine organism that was showing me the love during a morning of scientific diving in a marine reserve off the coast of Catalina Island, California.

Ecologists go online, the world benefits?

Science can take a page out of the World Health Organization’s book when it comes to tracking and aiding in global health. Its online database, the Global Public Health Intelligence Network (GPHIN), is an early disease detection system developed by Health Canada; it collects data on unusual disease events by monitoring news wires, websites and online newspapers in eight languages. But what can ecologists take away from this?

Ants use olfactory landmarks to navigate

Scientists have found that the ant is the first known animal both to process the location of odors and to use that information to create a cognitive map. And for ants, that means their pair of antennae work overtime to recognize and process multiple odors simultaneously. In other words, it seems ants smell in stereo.

Can birds affect tree growth?

Growing conditions, such as water and nutrient supply, are the major determinates of tree growth, but insectivorous birds can also play an important role, say scientists in a study published in the January issue of Ecology. Under the right conditions, birds contribute to whole tree growth by preying on herbaceous arthropods, such as leafhoppers, caterpillars and grasshoppers…

Research demonstrates that marine protected areas aid coral reefs

Research has shown that marine protected areas (MPAs)—areas where fishing and other potentially destructive activities are regulated—are benefitting, not just the fish habitats they are known to aid, but nearby coral reefs as well. MPAs may benefit corals by restoring reef-based food webs and protecting damage from anchors and nutrient runoff…
