In: J. Rosenthal (Ed.). Drug discovery, economic development and conservation: The International Cooperative Biodiversity Groups. Pharm. Biol. Vol 37, Supplement, pp. 55-68.
(Pharmaceutical Biology 37(Supplement):55–68. 1999, 1999)
This paper describes the Costa Rican International Collaborative Biodiversity Group (ICBG), which was designed to introduce insects and other arthropods as a source of pharmaceutical compounds, and to generate knowledge ...
Does a polyphagous caterpillar have the same gut microbiota when feeding on different species of food plants?
(Revista de Biología Tropical 50(2): 547-560, 2002, 2002)
We used classical culture techniques to explore gut bacteria and changes associated with dietary change in the highly polyphagous, tropical caterpillar Automeris zugana(Saturniidae). Fifty-five third instar wild-caught ...

Efecto de extractos de artrópodos sobre la multiplicación del Toxoplasma gondiidentro de macrófagos peritoneales de ratón
(Rev. Biol. Trop. 51(2): 317-320, 2003, 2003)
Treatment of toxoplasmosis usually causes secondary effects. It is important to find active substances extracted from natural organisms. In this work we studied some arthropod extracts that have effect against Toxoplasma ...

(Rev. Biol. Trop. (Int. J. Trop. Biol. ISSN-0034-7744) Vol. 56 (Suppl. 4): 175-189, December 2008, 2008-12)
Three Thalassia testudinumseagrass beds were studied at Cahuita National Park, from August 2003 to August 2006. Additionally, biomass samples of this species were collected at the Gandoca-Manzanillo National Wildlife Refuge, ...
A Comparison of four Methods to Evaluate the Butterfly Abundance. Using a Tropical Community
(Journal of the Lepidopterists' Society 45(3), 1991, 241-243, 1991-03-18)
In recent years. several transect methods to evaluate the abundance of butterflies have been proposed (Pollard, E. 1977, Biol. Conserv. 12:115—134; Feltwell, 3. 1982. Proc. Trans. Br. Entomol. Nat. Hist. Soc. 15:17—24). ...
