Recovery of oil palms (Elaeis guineensis Jacq.) affected by spear rots
(2015)
Spear rot or PC (for the Spanish name pudrición del cogollo), known locally in Costa Rica as ‘flecha seca’ is a disorder that affects the development, physiology and yield of the oil palm. It is associated with the ...
Adaptation of biomixtures for carbofuran degradation in on-farm biopurification systems in tropical regions
(2015-07)
A biomixture constitutes the active core of the on-farm biopurification systems, employed for the detoxification of pesticide-containing wastewaters. As biomixtures should be prepared considering the available local ...
A microbial consortium from a biomixture swiftly degrades high concentrations of carbofuran in fluidized-bed reactors
(2016)
An on-farm biopurification system (BPS) biomixture, with proven capacity to degrade carbofuran (CBF) was used as inoculum for a selective-enrichment process to obtain a bacterial consortium capable of using CBF as a sole ...
Response of a Specialist Bat to the Loss of a Critical Resource
(2011-12)
Human activities have negatively impacted many species, particularly those with unique traits that restrict their use of resources and conditions to specific habitats. Unfortunately, few studies have been able to isolate ...
Nephila clavipes spiders (Araneae: Nephilidae) keep track of captured prey counts: testing for a sense of numerosity in an orb-weaver
(Animal Cognition DOI 10.1007/s10071-014-0801-9, 2014-08-28)
Nephila clavipes golden orb-web spiders accumulate prey larders on their webs and search for them if they are removed from their web. Spiders that lose larger larders (i.e., spiders that lose larders consisting of more ...
Response of air surface temperature over Central America to oceanic climate variability indices.
(2002-12)
In this study were used 337 grid points (0.5 ° latitude x 0. 5° longitude), over Central America, from a monthly air surface temperature data set. The annual cycle, secular trend and decadal variability were removed and ...
Antivenoms for the treatment of snakebite envenomings: The road ahead
(2011-05)
The parenteral administration of antivenoms is the cornerstone of snakebite envenoming therapy. Efforts are made to ensure that antivenoms of adequate efficacy and safety are available world-wide. We address the main issues ...
Comparison between IgG and F(ab′)2 polyvalent antivenoms: neutralization of systemic effects induced by Bothrops asper venom in mice, extravasation to muscle tissue, and potential for induction of adverse reactions
(2001-06)
Whole IgG and F(ab′)2 equine-derived polyvalent (Crotalinae) antivenoms, prepared from the same batch of hyperimmune plasma, were compared in terms of neutralization of the lethal and defibrinating activities induced by ...
Assessment of the viral safety of antivenoms fractionated from equine plasma
(2004-09)
Antivenoms are preparations of intact or fragmented (F(ab')2 or Fab) immunoglobulin G (IgG) used in human medicine to treat the severe envenomings resulting from the bites and stings of various animals, such as snakes, ...
Modifying harvesting time as a tool to reduce nutrient export by timber extraction: a case study in planted teak (Tectona grandis L.f.) forests in Costa Rica
(2016)
Despite its low nutrient concentration, the high amount of biomass accumulated in the tree stem makes it an important nutrient sink. Hence, nutrient loss through timber removal at harvesting is a major cause of nutrient ...
