By: Clara Gomez The world’s seafood stocks will have completely collapsed by the year 2050, scientists say.  According to a study done by a group of economists and ecologists, the growth of the human population combined with unsustainable fishing practices and the devastating loss of biodiversity will lead to the collapse of fish populations in the next 35 years, if trends continue on their current path.

Cesar Barrio-Amoros holds a PhD in biology and is a notable taxonomist, herpetologist, author, and photographer. Following his experience in the Osa, reflected below, Cesar has planned to lead a reptile and amphibian workshop at Piro Biological Station next May or June, the beginning of the wet season. I have traveled throughout most of Latin America in search of amazing herping spectacles. In the Galapagos, I saw marine iguanas (Amblyrhynchus cristatus) and Galapagos giant tortoises (Chelonoidis nigra). I witnessed an astonishing diversity of poison frogs in Peru and made some...

Sea Turtles / 11.09.2012

[caption id="attachment_4373" align="alignleft" width="300"] A Green sea turtle nests on Pejeperro Beach[/caption] With the same clumsiness as their mothers, the small reptiles descend slowly down the sloped beach. One by one they go, leaving behind a trail of life in the sand. Seven weeks ago, after a journey spanning hundreds, perhaps thousands of kilometers, an adult olive ridley sea turtle (Lepidochelys olivacea) pushed through the foaming waves on Pejeperro beach in the Osa Peninsula, Costa Rica, to begin an ancient, unique and exquisite journey.

[caption id="attachment_2260" align="aligncenter" width="300" caption="Peltogyne Purpurea: An endemic species of Costa Rica and Western Panama, now very scarce because of overexplotation for its valuable timber."][/caption] Visiting a tropical forest can be overwhelming because of the enormous number of species found there, especially if you are talking about the Osa Peninsula, one of the most biologically diverse places in the world. This diversity is especially evident amongst plants which, as immobile organisms, are easily observed.  This same diversity, however, can be distressing for a person interested in identifying a species...

August 7th represented the second Day of Beach Cleaning along sea turtle nesting beaches in Osa.  With the participation of around 150 volunteers from the community, local hotels, personnel from Osa Conservation Area, Frontier volunteers and Osa Conservation employees, we were able to collect waste along 12 km of beaches, from Carate to Matapalo. Starting off early in the morning to take advantage of low tide, the groups divided up throughout the area with plastic bags, gloves, sun screen and lots of water.  The day of cleaning continued past...

Sea Turtles, Volunteers and Visitors / 04.11.2010

We’ve completed another month of the sea turtle conservation program on the Osa Peninsula, Costa Rica and we’re getting close to the end of the nesting season. After 4 months of tireless work by our field coordinators, field assistants and volunteers, we have registered a total of 1233 sea turtle nests, between Piro and Carate (Fig. 1). As I mentioned earlier, for logistical reasons, we cannot gather daily information from all beaches and visits to Rio Oro beach have been very limited, so this number of sea turtle nests should...
