Interplay of the PtsN (EIIANtr) protein of Pseudomonas putida with its target sensor kinase KdpD
The nitrogen phosphotransferase system (PTSNtr) of Pseudomonas putida is a multi-component regulatory device that participates in controlling a variety of physiological processes in a post-translational fashion. A general ...
Richness of cultivable endophytic fungi along an altitudinal gradient in wet forests of Costa Rica
We collected various plant species along an altitudinal gradient ranging from 400 to 2900 m in tropical wet forests of Costa Rica, isolated the associated endophytic fungi, and performed bioinformatic analyses to determine ...
Descripción ultraestructural de la hoja de tres especies de aráceas (Araceae) con características hidrofóbicas
Ultrastructural description of leaves from three araceae with hydrophobic characteristics
El estudio de los principios funcionales y estructurales de ciertas superficies biológicas permite su utilización en sistemas artificiales hechos por el hombre, campo denominado biomimetismo. Uno de los más importantes ...
Discovery of cahuitamycins as biofilm inhibitors derived from a convergent biosynthetic pathway
Pathogenic microorganisms often have the ability to attach to a surface, building a complex matrix where they colonize to form a biofilm. This cellular superstructure can display increased resistance to antibiotics and ...
Removal of carbofuran is not affected by co-application of chlorpyrifos in a coconut fiber/compost based biomixture after aging or pre-exposure
Las biomezclas constituyen la parte biológicamente activa de los sistemas de biopurificación (BPS), que se utilizan para tratar las aguas residuales que contienen pesticidas. El objetivo de este trabajo fue determinar si ...
Density, size, and biomass of Diadema mexicanum (Echinoidea) in Eastern Tropical Pacific coral reefs
Diadema is among the most abundant, widely dispersed, and ecologically important genera of sea urchin in tropical shallow waters. D. mexicanum is distributed from the Gulf of California to northern Peru, including the ...
Euphausiids (Crustacea: Euphausiacea) from a hotspot of marine biodiversity, Isla del Coco, Costa Rica, Eastern Tropical Pacific
Eufáusidos (Crustacea: Euphausiacea) de un punto caliente de biodiversidad marina, Isla del Coco, Costa Rica, Pacífico Tropical Oriental
Euphausiids have been well studied in several regions of the Pacific Ocean; however, there is less information regarding euphausiids in Costa Rican waters. We analyzed euphausiid specimens collected around Isla del Coco ...
Differentiation in reproductive traits of geminatemangrove crabs of the genus Aratus (Decapoda: Brachyura)across the Central American Isthmus
The mangrove crab Aratus pisonii was considered to have an amphi-American distribution; however, a recent study revealed that the Eastern Tropical Pacific populations were genetically distinct, thus representing a new ...
Abundance and Distribution Patterns of Thunnus albacares in Isla del Coco National Park through Predictive Habitat Suitability Models
Information on the distribution and habitat preferences of ecologically and commercially important species is essential for their management and protection. This is especially important as climate change, pollution, and ...
A new Muricea species (Cnidaria, Anthozoa, Octocorallia) from the eastern tropical Pacific
The genus Muricea is considered abundant and widely distributed along the eastern Pacific. Its occurrence in shallow waters has been recognised; however species from deeper than 30 m have been rarely recorded. During the ...
