Fungi in aquatic ecosystems
Fungi are phylogenetically and functionally diverse ubiquitous components of almost all ecosystems on Earth, including aquatic environments stretching from high montane lakes down to the deep ocean. Aquatic ecosystems, ...
Ammonium and phosphate removal using batch laboratory cultures by microalgae and cyanobacteria isolated from Costa Rica water bodies
Remoción de amonio y fosfato en cultivos de laboratorio con microalgas y cianobacterias aisladas de cuerpos de agua de Costa Rica
This research analyzed three green microalgae (Scenedesmus sp., Chlamydomonas sp., and Chlorella sp.) and two cyanobacteria (Synechocystis sp. as unicellular strain and Nostoc sp. as filamentous strain) native from Costa ...
A taxonomic revision of Monstera Adans. (Araceae: Monsteroideae) in Costa Rica
Monstera Adans. (Araceae: Monstereae) is revised for Costa Rica. Thirty-five species are recognised, of which one (M. deliciosa) is introduced. Of them, ten have been only very recently described and Monstera tablasensis ...
A New Quararibea (Malvaceae) from the Caribbean Lowlands of Costa Rica
We describe and illustrate a new species of Quararibea Aubl. from Costa Rica. Quararibea reflexipetalaCascante, J. Sánchez-Gonz. & W. S. Alverson is distinguished by its pleated petals with strongly reflexed and coiled ...
Evaluating factors that predict the structure of a commensalistic epiphyte–phorophyte network
A central issue in ecology is the understanding of the establishment of biotic interactions. We studied the factors that affect the assembly of the commensalistic interactions between vascular epiphytes and their host ...
Description of the larva and pupa of Limnephilus hamifer Flint 1963 (Trichoptera, Limnephilidae) from Costa Rica
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 ...
Trick or treat? Pollinator attraction in Vanilla pompona (Orchidaceae)
Natural pollination of Vanilla species remains poorly understood. Our research aimed at better understanding the pollinator attraction mechanism of the Neotropical species Vanilla pompona. Based on our results, we hypothesize ...
Impaired pesticide removal and detoxification by biomixtures during the simulated pesticide application cycle of a tropical agricultural system
Biopurification systems (BPS) or biobeds have been developed to attenuate point-source contamination due to inappropriate pesticide handling or disposal of agricultural wastewaters. The biomixture used for this strategy ...
Size at maturity of the Pacific bearded brotula (Ophidiidae: Brotula clarkae): a commercially exploited species in the Pacific of Costa Rica
Talla de madurez sexual del congrio rosado (Ophidiidae: Brotula clarkae): una especie de importancia comercial en el Pacífico de Costa Rica
The deep-water shrimp fishery is of great commercial importance along the Pacific coast of Latin America. In Costa Rica, shrimp resources have declined considerably over the last decade. Therefore, fisheries have shifted ...
Copulatory dialogue: female spiders sing during copulation to influence male genitalic movements
(Animal Behaviour, 2006, 72, 413-421, 2006)
Female behaviour during copulation that could function as communication with the male is probably more common than previously appreciated, but its functional significance remains little studied. Stridulation during copulation ...
