Gold has been mined in the area surrounding the small Costa Rican town of Las Juntas for over 100 years. In the beginning, large-scale North American mining companies exploited the people who worked for them. Today the large-scale mining operations are gone, but the old tunnels are still worked by local artisanal miners or coligalleros as they are called in this town. Conditions in the mines are even more dangerous. Minors process the gold using mercury in their own backyards along the rivers, threatening their own health as well as the ecology and public health of this community and that on a global scale. This book documents the linkage between the human experience and ecology of Las Juntas through the words of a natural scientist and the images produced by a documentary photographer. The photographs are not meant to illustrate or support the text, but rather tell the same story in a different way. This type of collaboration between a scientist and an artist is rare, but is essential for truly understanding the give-and-take among a cultural heritage, social condition, and the ecology of an area. This is a case study that both honors this community and its rich culture and history, and serves to increase awareness of the environmental and human implications of gold extraction by adding a personal element to this story. It also examines sustainable approaches to protecting the environment, and the needs of individuals and communities whose heritage and livelihood come from this activity.

Описание: Life began in the sea, and even today most of the deep diversity of the planet is marine. This is often forgotten, especially in tropical countries like Costa Rica, renowned for their rain forests and the multitude of life forms found therein. Thus this book focusing on marine diversity of Costa Rica is particularly welcome. How many marine species are there in Costa Rica? The authors report a total of 6,777 species, or 3. 5% of the world’s total. Yet the vast majority of marine species have yet to be formally described. Recent estimates of the numbers of species on coral reefs range from 1–9 million, so that the true number of marine species in Costa Rica is certainly far higher. In some groups the numbers are likely to be vastly higher because to date they have been so little studied. Only one species of nematode is reported, despite the fact that it has been said that nematodes are the most diverse of all marine groups. In better studied groups such as mollusks and crustaceans, reported numbers are in the thousands, but even in these groups many species remain to be described. Indeed the task of describing marine species is daunting – if there really are about 9 million marine species and Costa Rica has 3. 5% of them, then the total number would be over 300,000. Clearly, so much remains to be done that new approaches are needed. Genetic methods have en- mous promise in this regard.

The Pocket Guide to the Insects of Costa Rica reveals the sheer numbers and diversity of insects and arthropods of the tropics. Every square meter of rainforest and cloud forest in Costa Rica offers up multitudes of gemlike tiny creatures with enough wonders to keep an entomologist busy for a lifetime. But given that Costa Rica is home to potentially more than 250,000 species—the majority of which have yet to be named—where to begin?
This Pocket Guide helps orient those new to the insect world, featuring the species that one would most likely encounter on a walk through the forests of Costa Rica. Individual species accounts offer key physical characteristics, along with fascinating natural history information, while range maps offer further clues to help identify the insect that has just landed on your trail way. Finally, there are the stunning photos—a happy reminder of your time spent in the wilds of Costa Rica.

Описание:
Encounter some of the most beautiful creatures in Costa Rica in Piotr Naskrecki’s Hidden Kingdom. This book is a visual journey into the world of the insects and their relatives that dominate all terrestrial habitats in Costa Rica through their sheer numbers, biomass, and the ecological functions they perform. Naskrecki’s stunning photographs serve as both a tool to help identify the insects that a visitor to Costa Rica is likely to encounter, and as an illustration of their diverse behaviors and ecological roles.
Through high-impact imagery and engaging narrative about insects and their evolutionary history, this book, an ideal companion on a visit to Costa Rica, reinforces or awakens in the readers their innate curiosity about the less appreciated elements of life on Earth. Each section of the book presents fascinating and useful facts about Costa Rica’s insects. Naskrecki’s photographs show the variety of morphological adaptations, survival strategies, and interlocking roles that insects play in tropical ecosystems.
At the biological crossroads of the Americas, Costa Rica hosts an astonishing array of plants and animals—over half a million species! Ecotourists, birders, and biologists come from around the world, drawn by the likelihood of seeing more than three or four hundred species of birds and other animals during even a short stay. To help all these visitors, as well as local residents, identify and enjoy the wildlife of Costa Rica, Carrol Henderson published Field Guide to the Wildlife of Costa Rica in 2002, and it instantly became the indispensable guide.
Now Henderson has created a dedicated field guide to more than one hundred tropical butterflies, moths, and other invertebrates that travelers are most likely to see while exploring the wild lands of Costa Rica. He includes fascinating information on their natural history, ecology, identification, and behavior gleaned from his forty years of travels and wildlife viewing, as well as details on where to see these remarkable and beautiful creatures. The butterflies, moths, and other invertebrates are illustrated by over 180 stunning and colorful photographs—most of which were taken in the wild by Henderson. A detailed and invaluable appendix that identifies many of Costa Rica's best wildlife-watching destinations, lodges, and contact information for trip-planning purposes completes the volume.

Описание: Phocid (or earless or true) seals are ecologically diverse, occupying habitats from the tropics to the poles in marine and freshwater and feeding on anything from tiny zooplankton to other marine mammals. There are 18 species of phocid seals, the smallest species (ringed seal) is more than 20 times smaller than the largest (southern elephant seal), with marked sexual dimorphism present in some species. This book examines the behavior, ecology, and physiology that allow phocid seals to inhabit such a wide range of habitats. The book is composed of 16 chapters written by 37 authors from 8 countries. The book first describes the general patterns of phocid behavior, followed by descriptions of what is known about well-studied species. We have taken a holistic approach, focusing not only on the behaviors themselves but also on the factors that constrain the expression of behavior and the proximate mechanisms driving behavior. In many cases, the chapters represent collaborations between well-established researchers and early-mid career individuals who bring new perspectives to help carry the field of phocid behavioral ecology well into the future.

Описание: Science for Ecosystem-based Management: Narragansett Bay in the 21st Century addresses the broad problem of coastal nutrient pollution. In the U.S., approximately two thirds of the coastal rivers and bays are moderately to severely degraded from nutrient pollution. However, debates continue about how large a problem nutrient pollution is and what actions to take, and since effective management requires decisions at a local scale, an in-depth case study can provide valuable guidance. Narragansett Bay is one of the best-studied estuaries in the world. Rhode Island has been developing regulatory and management actions to reduce nutrient inputs, particularly those of nitrogen, to the waters of Narragansett Bay. This book was developed in response to a symposium addressing this mandate with coastal/estuarine scientists and environmental management agency personnel. The contributors use long-term data sets to discuss the interactions among biological, ecological, chemical, and physical processes, and discuss what is known about nutrient inputs to the bay ecosystem, the impacts related to nutrient inputs, and how the ecosystem might respond to a sudden reduction in these inputs.
