(2017)Methodology: The data are 29 sediment samples and these were collected (September 2006) each 200m in a parallel transect on the low spring tide level in a sandy beach of the Caribbean coast of Costa Rica. The data are ... -
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 ... -
Bemisia tabaci Biotype Q is present in Costa Rica
(2011)Whiteflies are an insect group that comprises multiple species and biotypes, capable of affecting crops by phloem feeding, virus transmission and promotion of fungal colonization. The distribution of these pests is worldwide. ... -
Biodegradation of Polybrominated Diphenyl Ethersin Liquid Media and Sewage Sludge by Trametes versicolor
(2015)Polybrominated diphenyl ethers (PBDE) are widely employed as flame retardants and constitute a group of emerging pollutants of high persistence. The degradation of different PBDE commercial mixtures (penta-, octa- and ... -
Biogeographical assessment of myxomycete assemblages from Neotropical and Asian Palaeotropical forests
(2017-03-16)Aim Lowland/highland and Neotropical/Asian Palaeotropical assemblages of myxomycetes were compared to test the null hypothesis that neither species diversity nor species composition differs between the two ecoregions. ... -
Biología molecular del virus del rayado fino del maíz
(1986-06)A condensed report of research on the molecular biology of Maize Rayado Fino Virus is offered, along with a tentative model for the capsid structure that fits the biochemical analysis of this virus. Given the existence of ... -
Biology of snakes of the genus Tretanorhinus: an integrative review
(2019)Many aspects of the biology of various snake species remain unknown, and the extent of this lack of information is not always clear. As new research usually depends upon previous findings, the gaps in our knowledge and ... -
Birds in Coastal and Marine Environments
(Springer Science & Business Media, 2009)In Costa Rican coastal and marine environments (e.g., estuaries, mud- flats, islands, open ocean) 96 bird species have been recorded, 11% of the total avifauna in the country. This high diversity is primarily explained by ... -
Body distribution of Bothrops asper (terciopelo) snake venom myotoxin and its relationship to pathological changes
(1988)The distribution of 125I-labelled Bothrops asper myotoxin following i.m. and i.v. injections was studied in mice. After i.m. administration the toxin was concentrated in the injected gastrocnemius muscle, with relatively ... -
Borrelidin Induces the Unfolded Protein Response in Oral Cancer Cells and Chop-Dependent Apoptosis
(2015)Oral squamous cell carcinoma (OSCC) is the most common cancer affecting the oral cavity, and US clinics will register about 30,000 new patients in 2015. Current treatment modalities include chemotherapy, surgery, and ... -

Brachiopods, sipunculans, enteropneusts and metals from two estuarine tidal flats, Pacific, Costa Rica
(2016-09)Reports on the abundances and on metal concentrations in intertidal estuarine invertebrates from the Eastern Tropical Pacific are rare. Thus, the objectives of this report are to make accessible data on the abundances ... -
Brain structure–function associations in multi-generational families genetically enriched for bipolar disorder
(2015-05)Recent theories regarding the pathophysiology of bipolar disorder suggest contributions of both neurodevelopmental and neurodegenerative processes. While structural neuroimaging studies indicate disease-associated ... -
Brief research history and status of myxomycete conservation in the Neotropics
