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 ...
Updated checklist and analysis of completeness of the marine fish fauna of Isla del Coco, Pacific of Costa Rica
Isla del Coco, Costa Rica, is one of the five groups of oceanic islands of the Eastern Tropical Pacific (ETP), and is considered one of the most diverse. Since the mid-19th century, it has been the target of a number of ...
Growth and hydrogen production of outdoor cultures of Synechocystis PCC 6803
Synechocystis sp. PCC 6803, a freshwater cyanobacterium, was cultivated outdoors in a 50 L tubular photobioreactor to study the acclimation of cells to solar light in cultures grown at different initial mean biomass ...
Changes in abundance and composition of a Caribbean coral reef zooplankton community after 25 years
Cambios en abundancia y composición de una comunidad de zooplancton arrecifal en el Caribe 25 años después
Coral reef zooplankton represents a key community in coral ecosystems, as they are involved in trophic and biogeochemical dynamics, and recruitment processes. Zooplankton abundance, composition and biomass were surveyed ...
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 ...
A revision of the genus Muricea Lamouroux, 1821 (Anthozoa, Octocorallia) in the eastern Pacific. Part II
The species of the genus Muricea were mainly described from 1846 to 1870. After that very few contributions were published. Although the highest richness of Muricea species is in the eastern Pacific shallow waters, a ...
DNA-assisted identification of Caulerpa (Caulerpaceae, Chlorophyta) reduces species richness estimates for the Eastern Tropical Pacific
Taxonomy and species richness estimates for the genus Caulerpa have proven challenging due to the difficulty of assessing morphological species limits. In the present study we evaluate the taxonomy of the genus and assess ...
New records of snipe eels (Anguilliformes: Nemichthyidae) from the Pacific coast of lower Central America
Background: New records of occurrence of two snipe eels (Avocettina bowersii and Nemichthys scolopaceus), poorly known for the Pacific coast of Costa Rica and Panama are herein reported. Results: Specimens, 45 in total ...
Variation in the whole mitogenome of reef-building Porites corals
The study of complete mitochondrial genomes (mitogenomes) revealed different gene rearrangements, highly variable markers, and delineated clades that have aided the understanding of the evolutionary history in corals. In ...
A new species of Leptoderma Vaillant, 1886 (Osmeriformes: Alepocephalidae) from the Pacific coast of Central America
A new species of Leptoderma Vaillant, 1886 is described from a single specimen trawled at 1368–1406 m depth off El Salvador, Central America, tropical eastern Pacific. Leptoderma ospesca n. sp. can be readily distinguished ...
