Batimetría de la plataforma insular alrededor de la Isla del Coco, Costa Rica
(2001-12-01)La batimetría de la Isla del Coco (Patrimonio Mundial Cultural y Natural de la UNESCO), localizada a 500 Km de la costa en el Pacífico de Costa Rica, no es muy conocida. Posee un ambiente de una alta biodiversidad marina ... -
Batimetría, modelos de elevación digital y sus aplicaciones
(2009)En este trabajo se resume la historia de los sondeos batimétricos y los equipos utilizados en el estudio de la rugosidad marina. Se hace referencia a las distintas instituciones internacionales a cargo de la elaboración ... -
Bats mimic hymenopteran insect sounds to deter predators
(2022)This study explores interspecific acoustic mimicry in mammals, particularly focusing on the greater mouse-eared bat (Myotis myotis) distress calls. These calls imitate stinging bee and wasp sounds, aiming to deter avian ... -
Bauhinia proboscidea
(2021)Bauhinia proboscidea is a shrub or tree from 4 to 12 metres tall with a diameter from 10 to 25 cm when mature, sometimes reported as scandent. This species occurs on the Pacific slope of central and southern Costa Rica and ... -
Bauhinia proboscidea (Fabaceae: Cercidoideae), a new species from Costa Rica and Panama, with notes on B. beguinotii, B. gorgonae and B. pansamalana
(2018)Bauhinia proboscidea, a new species from Costa Rica and Panama, is described and illustrated, and compared to the closely related B. pansamalana of southern Mexico, Guatemala and Honduras. It is also compared with B. ... -
Baulamycins A and B, Broad-Spectrum Antibiotics Identified as Inhibitors of Siderophore Biosynthesis in Staphylococcus aureus and Bacillus anthracis
(2014)Siderophores are high-affinity iron chelators produced by microorganisms and frequently contribute to the virulence of human pathogens. Targeted inhibition of the biosynthesis of siderophores staphyloferrin B of Staphylococcus ... -

Begomovirus de importancia económica que pueden encontrarse en ambientes protegidos
(2015)Los begomovirus (familia Geminiviridae) son un grupo de virus de plantas transmitidos por la mosca blanca Bemisia tabaci (o ‘palomilla’). Las enfermedades causadas por estos patógenos se han propagado a nivel mundial, ... -
Behavioral changes across novelty habituation: Contextual modulation of self-grooming after a stress event
(2018-07)Grooming is a widespread behavior in the animal kingdom primarily geared towards the care of the body surface; nonetheless, other behavioral functions have been investigated and postulated. For example, rodents display ... -
Behavioural responses of reptiles to visitors of protected areas in Costa Rica
(2016)Tourists can have a strong impact on the behaviour of wild animals, modifying foraging strategies, diet and habitat use, increasing stress, and altering communication and escaping behaviour. Such behavioural changes have ... -
