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

7 editions published between 2006 and 2009 in English and held by 357 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

Designing conservation projects by Julian Oliver Caldecott( )

3 editions published between 1996 and 2010 in English and held by 26 WorldCat member libraries 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

Vascular epiphytes : general biology and related biota by David H Benzing( )

1 edition published in 2011 in English and held by 5 WorldCat member libraries worldwide

This synthesis of the growing body of information from research on epiphytes and their relations with other tropical biota provides a comprehensive overview of basic functions, life history, evolution, and the place of epiphytes in complex tropical communities. Epiphytes comprise more than one-third of the tropical vascular flora in some tropical forests. Growing within tropical forest canopies, epiphytes are subject to severe environmental constraints, and their diverse adaptations make them a rich resource for studies of water balance, nutrition, reproduction and evolution

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
