(2018)Maxillariella prostrata, a new species from Costa Rica and Panama is described and illustrated. This species is similar to M. acervata but differs in having a prostrate habit, elliptic leaves up to 2 cm long, pseudobulbs ... -
A new Muscarella from Tapanti National Park, Costa Rica
(2021)A new species of Muscarella from Costa Rica, is described and illustrated. Muscarella tapantiensis most resembles M. coeloglossa but differs in the longer pedicels (3-5 vs. 1-2 mm), the shorter (2.5-2.8 vs. 3.75 mm), connate ... -
A new species of Eurystyles (Orchidaceae: Spiranthinae) from Costa Rica
(2020)Eurystyles comprises about 23 species ranging from Mexico to northernArgentina. Six species are recognized in Mexico and Central America and three in Costa Rica. A new species, named E. uxoris, is here described and ... -
A review of the Costa Rican myxomycetes (Amebozoa)
(2010)There has not been a comprehensive review of the taxonomic composition of the assemblage of myxomycetes known from Costa Rica since 1975. As a result of a series of studies carried out in the country during the last decade, ... -
Additions to the myxobiota of Central America
(2014)Given the fact that until recently the myxomycetes were an understudied group in Central America, it is not surprising that the number of new records for most countries is currently increasing at a steady pace. This is ... -
Can the location of the isolation laboratory affect the generation of myxomycete data using moist chambers? An experiment in the Neotropics
(2021-03-11)The moist chamber technique, as it is used in myxomycete research, is an extremely useful method to optimize project resources. However, as it occurs with any laboratory-based protocol, the usefulness of this technique ... -
Carbono, bosques y micorrizas: una “negación de investigación imperativa”
(2014)El estudio integrado de los sistemas biológicos asociados con el secuestro y fijación de carbono no ha sido prioritario en la determinación de los protocolos de cuantificación de este elemento. Este caso de reduccionismo ... -
Description of the final instar nymphs of seven species from Anacroneuria Klapálek (Plecoptera: Perlidae) in Costa Rica, and first record for an additional genus in Central America
(2011)The final nymphal stages for seven species of Anacroneuria Klapálek from Costa Rica are described for the first time based upon reared specimens: A. benedettoi Stark, 1998, A. divisa (Navás, 1924), A. holzenthali Stark, ... -

(2018)Se describe e ilustra por primera vez la larva y pupa de Limnephilus hamifer Flint 1963. La descripción está basada en material recolectado y criado del macizo montañoso Cerro de la Muerte de Costa Rica, además de material ... -
Distribución de las formas de vida en la flora costarricense
(2008)La diversidad de plantas de un país o región se puede interpretar desde la perspectiva ecológica de las especies utilizando un sistema de clasificación por “formas de vida”. En este trabajo (1) se describe la diversidad ... -
Does habitat loss affect tropical myxomycetes?
(2014-10-29)The effect of habitat loss on the dynamics of myxomycete assemblages has been poorly studied thus far. For this reason, a premontane moist forest surrounded by human-created pastures on the Caribbean slope of Costa Rica ... -
Ecological patterns of Costa Rican myxomycetes
(2009-10)Ecological patterns of tropical myxomycetes have been subjected to study only during the last decade. An exhaustive analysis of an extensive dataset for a single tropical country is lacking. For this reason, the present ... -
Evolutionary diversification and historical biogeography of orchidaceae in Central America with emphasis on Costa Rica and Panama
(2019)In this thesis, I targeted the orchid genus Lepanthes, one of the six genera of angiosperms that surpasses 1,000 species in the Neotropics, as a study model to investigate the evolutionary processes that promoted species ... -
Factors affecting phenological patterns of bombacaceous trees in seasonal forests in Costa Rica and Mexico
(2003)We compared phenological patterns of tree species of the family Bombacaceae in three seasonal forests in Mexico and Costa Rica whose dry seasons vary in duration and intensity. The objectives were to (1) determine intraspecific ... -
Freshwater Decapod Diversity and Conservation in Central America and the Caribbean
(2016)This chapter provides an overview of the species diversity and conservation status of the freshwater decapods in Central America and the Caribbean islands that date back to the late 1800s in both areas. The majority of the ... -
