How does one go about identifying dolphins? Well, pioneering biologists studying various species discovered ingenious ways to distinguish individuals. Jaguars have unique spots. Gorillas have unique nose prints. Dolphins have unique dorsal fins. By examining the shape, natural markings, scars and trailing edge, a dorsal may appear as distinct as a fingerprint. Of course dolphins don’t sit quietly at the surface while you study the intricacies of their dorsal patterns, so ID work is best done through photos. Luckily, we managed to get photographs for almost 90 percent of our dolphin sightings.

As Published in The Leader-Telegram They have a saying in Costa Rica: "Pura vida." It literally translates as "pure life," but to Costa Ricans, it can be inserted into many contexts and applications: "Thank you," "You're welcome," "So it goes," "Wonderful." It is used so freely here I wouldn't be surprised if it meant, "Pass the papaya, por favor." I'd dreamed of visiting Costa Rica since I was 12, and recently for two glorious weeks I got to sample the "pure life" - visiting the southernmost quarter of this West Virginia-sized nation - from San Jose down nearly to Panama. My introduction to the Pacific rain forest lowlands began with Roy Orozco, a soft-spoken, gracious naturalist out of Quepos. First light for birding in the tropics is 5:30 a.m., so Roy picked me up at 4 a.m. at the Costa Verde II parking lot near Quepos to drive an hour and a half up the coast to Carara National Park, west of San Jose. Carara, one of Costa Rica's marquee ecotourism destinations, is a unique mix of "life zones," where the drier habitat of the north meets the wet lowlands of the south.

However, when you’re a disease ecologist like my colleague Peter and me, it’s sometimes hard to keep parasites out of your head. Figuratively, that is! So, even before our first trip to Cerro Osa in January 2011, as part of a tropical ecology course with Princeton University, we had begun thinking of ways we could tie in the unique ecology of the Osa with our own research. Trawling through the wonderfully informative Osa Conservation website, we had eagerly devoured information on the landscape and ecosystem we would be exploring. We found out how Osa Conservation was working to create a biological corridor of rainforest habitat between Cabo Matapalo at one end of the peninsula and Corcovado National Park at the other. That intrigued us. Both of us also have conservation backgrounds, and so we were well aware of the positive benefits of connecting patches of habitat, such as giving predators larger areas to hunt in, and decreasing the chance of inbreeding, which can occur if animals are squished into too small an area. However, we also knew of some theoretical work that our boss, Professor Andy Dobson, had done looking at how corridors, by increasing connectivity between animal populations, might affect disease transmission. Could the Osa peninsula provide us with a natural laboratory for testing some of these ideas?

But the most commonly seen whale inside the Golfo Dulce is the Humpback whale (Megaptera novaeangliae), a species that annually migrates from colder feeding grounds near the...
