100 caterpillars : portraits from the tropical forests of Costa Rica by Jeffrey C Miller( Book )

6 editions published between 2006 and 2009 in English and held by 363 WorldCat member libraries worldwide

"Gathered by biologists Daniel Janzen, Winifred Hallwachs, and Jeffrey Miller in the tropical dry forests, cloud forests, and rain forests of northwestern Costa Rica, over 100 large-format photographs of caterpillars document the variety of shapes, vivid colors, and cryptic markings among these species. The pictures are accompanied by capsule species accounts - revealing life histories as diverse as their forms - and images of the adult butterfly or moth. Throughout, the authors convey an intimate sense of these creatures - studied over twenty-five years - by focusing on how their features figure in their behavior and ecology, and on the beauty of nature in this life stage, as well as the nature of that beauty."--Jacket

Costa Rica paradise reclaimed( Visual )

2 editions published in 1987 in English and held by 3 WorldCat member libraries worldwide

Dan Jansen, an American professor of biology, has a dream of recreating the ecosystem of Costa Rica to accomodate the many native species of animals there, many of which are endangered. The dry forest is vanishing, and Jansen believes it must be saved before the entire ecosystem collapses. He seeks cooperation with local farmers to change their policy of setting controlled fires to clear their pastureland
Revision of the New World species of Houghia Coquillett (Diptera, Tachinidae) reared from caterpillars in Area de Conservación Guanacaste, Costa Rica by Alan J Fleming( Book )

3 editions published in 2014 in English and held by 3 WorldCat member libraries worldwide

Thirty-five species of the genus Houghia Coquillett (Tachinidae, Exoristinae, Goniini) are described, 34 new and one previously described, all reared from various species of caterpillars collected in Area de Conservación Guanacaste (ACG), northwestern Costa Rica. A matrix of character states and a key for the identification of the species are also provided. By coupling morphology, life history and molecular data, with photographic documentation, a clear and concise description of each species is provided. The following 34 new species of Houghia are described, all authored by Fleming and Wood: H. aerata sp. nov., H. aurifera sp. nov., H. biseriata sp. nov., H. bivittata sp. nov., H. blancoi sp. nov., H. brevipilosa sp. nov., H. chavarriae sp. nov., H. confinis sp. nov., H. delospilota sp. nov., H. destituta sp. nov., H. fimbriata sp. nov., H. gracilis sp. nov., H. graciloides sp. nov., H. griseifrons sp. nov., H. inflatipalpis sp. nov., H. latigena sp. nov., H. latilobus sp. nov., H. longicercus sp. nov., H. longipilosa sp. nov., H. luteiventris sp. nov., H. macilenta sp. nov., H. marini sp. nov., H. matarritai sp. nov., H. nigrofemur sp. nov., H. ochrofemur sp. nov., H. omissa sp. nov., H. pallida sp. nov., H. parmata sp. nov., H. pilosifrons sp. nov., H. romeroae sp. nov., H. sexmaculata sp. nov., H. spathulata sp. nov., H. triangularis sp. nov., and H. velutina sp. nov. The following are proposed by Wood as new synonyms of Houghia: Actinoprosopa Townsend syn. nov., Agrarialia Curran syn. nov., Anhangabahuia Townsend syn. nov., Aridalia Curran syn. nov., Bolohoughia Townsend syn. nov., Carceliocephala Townsend syn. nov., Chrysohoughia Townsend syn. nov., Eumacrohoughia Townsend syn. nov., Macrohoughia Townsend syn. nov., Orohoughia Townsend syn. nov., Pammaerus Aldrich syn. nov., Pararrhinactia Townsend syn. nov., Petrargyrops Townsend syn. nov., Sisyrohoughia Townsend syn. nov., Tapajohoughia Townsend syn. nov., and Verrugomyia Townsend syn. nov. New combinations are proposed by Wood as a result of the new synonymies, as follows: H. analis (Townsend) comb. nov., H. approximata (van der Wulp) comb. nov., H. aurata (Townsend) comb. nov., H. aurometallica (Townsend) comb. nov., H. bistrigata (van der Wulp) comb. nov., H. calcarata (van der Wulp) comb. nov., H. chlorescens (Townsend) comb. nov., H. crypta (Townsend) comb. nov., H. facialis (Townsend) comb. nov., H. impedita(van der Wulp) comb. nov., H. lateralis (Curran) comb. nov., H. leptotrichopa (Brauer & Bergenstamm) comb. nov., H. maris (Townsend) comb. nov., H. marmorata (Townsend) comb. nov., H. minor (Thompson) comb. nov., H. nuda(Townsend) comb. nov., H. orbitalis (Townsend) comb. nov., H. orbitalis (Curran) comb. nov., H. parva (Townsend) comb. nov., H. plagioides (van der Wulp) comb. nov., H. punctiger (Townsend) comb. nov., H. quadra (Wiedemann) comb. nov., H. sexualis (Curran) comb. nov., H. similis (Townsend) comb. nov., H. simillima (Thompson) comb. nov., H. sordida (van der Wulp) comb. nov., H. tenuiseta (Macquart) comb. nov., and H. tropica (Townsend) comb. nov. Houghia orbitalis (Curran, 1934a, described in Sturmia), junior homonym of H. orbitalis (Townsend, 1927, described in Verrugomyia) is synonymized by Wood with Houghia leptotrichopa (Brauer & Bergenstamm, 1891), and need not be renamed while in synonymy. Lectotypes are designated by Wood for the following ten valid species of Houghia: Anisia approximata van der Wulp, 1890, Actinoprosopa facialis Townsend, 1927, Masicera impedita van der Wulp, 1890, Macrohoughia marmorata Townsend, 1927, Eumacrohoughia minor Thompson, 1963, Prospherysa plagioides van der Wulp, 1890, Petrargyrops punctiger Townsend, 1927, Carceliocephala simillima Thompson, 1963, Masicera sordida van der Wulp, 1890, and Masicera tenuiseta Macquart, 1846: 292

The Wisdom of water the journey of the Stroud Water Research Center( Visual )

1 edition published in 2001 in English and held by 2 WorldCat member libraries worldwide

Only three percent of the world's water is fresh water, making it our planet's most precious resource. In 1967, a small group of scientists began a remarkable journey to study and comprehend the complex nature of fresh water streams and rivers. In the ensuing years the Stroud Water Research Center has become the acknowledged leader in this increasingly critical field of scientific endeavor. Filmed on location in Pennsylvania, New York, and Costa Rica, this portrait captuires the essence of the Stroud Center's mission. Join Robert F. Kennedy, Jr., renowned National Academy of Science members Dr. Ruth Patrick and Dr. Daniel Janzen, and Stroud Water Research Center scientists as they seek The Wisdom of Water. -- cassette cover
Revision of the genus Pseudapanteles (Hymenoptera, Braconidae, Microgastrinae), with emphasis on the species in Area de Conservación Guanacaste, northwestern Costa Rica by José L Fernández-Triana( Book )

Designing conservation projects by Julian Oliver Caldecott( Book )

2 editions published in 1996 in English and held by 1 WorldCat member library worldwide

"What are the challenges involved in protecting biodiversity in tropical terrestrial and coastal ecosystems? What practical lessons can be learned from conservation projects? And what are the procedures and attitudes of governments, NGOs, donor agencies, development banks, and consulting firms? These key questions are all answered, drawing on the author's extensive experience of conservation projects in Malaysia, Nigeria, China, Indonesia, the Philippines, Costa Rica, and elsewhere. Project descriptions are used to illustrate the growth of two important themes in conservation: increasing the awareness of the economic value of biodiversity among decision makers; and enabling and encouraging local people to participate in designing and implementing projects."--BOOK JACKET
