Four new species of Pleurothallis (Orchidaceae: Pleurothallidinae) from the Valle del Cauca Department in Colombia
(2017)Pleurothallis indecora, P. juvenilis, P. lueriana and P. queremalensis are described from material collected in the municipality of Dagua, department of Valle del Cauca, Colombia. The four species were found during field ... -
Frankliniella occidentalis (Pergande 1895) (Thripidae: Thripinae) un posible bioindicador de la condición del medio ambiente
(2014)En este trabajo se evalúa la utilidad de Frankliniella occidentalis como especie bioindicadora. El estudio consta de dos enfoques 1) los datos de la colección de Thysanoptera de Costa Rica sobre la presencia de esta ... -
Frankliniella, dos nuevos registros en México y Costa Rica: distribución y sus implicaciones en ecología y taxonomía (Thysanoptera: Thripidae)
(2015-12-05)En este trabajo se presentan dos nuevos informes de especies de Frankliniella Karny 1910 una para Costa Rica de Frankliniella albacuriosa Johansen 1998 y Frankliniella caribae Retana-Salazar 2010 para dos estados de México. ... -
Fraude en la autoría de artículos científicos
(Revista Biomédica, vol. 18, n. 2, 2007-05)El fraude científico como toda conducta delictiva, implica el engaño deliberado al margen de las normas éticas. Los investigadores corruptos inventan desde datos hasta experimentos; pero, el tipo de fraude científico más ... -
Frequency and synchronisation features of a highly overlapped duet changes according to the context
(2019)Territorial defence and maintaining contact are two hypotheses of duet functions. Nevertheless, the acoustic characteristics of duets in these contexts have been poorly quantified. This work aimed to compare the spectrotemporal ... -
Fresh biochar application provokes a reduction of nitrate which is unexplained by conventional mechanisms
(2021)Soil-applied biochar has been reported to possess the potential to mitigate nitrate leaching and thus, exert beneficial effects beyond carbon sequestration. The main objective of the present study is to confirm if a pine ... -
Freshwater crabs as predators and prey: the case of Ptychophallus uncinatus Campos & Lemaitre, 1999 (Brachyura, Pseudothelphusidae) from Costa Rica, Central America
(2019)Primary freshwater crabs are an important component of the food web in aquatic ecosystems, but our knowledge about the role of these decapods as predators and as prey is far from complete. Here we report observations of ... -
Freshwater Decapod Diversity and Conservation in Central America and the Caribbean
(2016)This chapter provides an overview of the species diversity and conservation status of the freshwater decapods in Central America and the Caribbean islands that date back to the late 1800s in both areas. The majority of the ... -
From dirt to industrial applications: Pseudomonas putida as a Synthetic Biology chassis for hosting harsh biochemical reactions
(2016-10)The soil bacterium Pseudomonas putida is endowed with a central carbon metabolic network capable of fulfilling high demands of reducing power. This situation arises from a unique metabolic architecture that encompasses the ... -
¿Funcionan realmente los microorganismos de montaña (MM) como estrategia de biofertilización? Un enfoque de ingeniería de biosistemas
(2017-06-29)El uso de microorganismos en aplicaciones ingenieriles, en particular desde un contexto de ingeniería de biosistemas tropicales, es útil para comprender el efecto de variables que determinan la dinámica microbiológica ... -
Function of the upper tangle in webs of young Leucauge argyra (Araneae: Tetragnathidae)
(2011)Ontogenetic changes in web structure occur in many spiders of different families, but the functional adaptation of differences in web structure is unknown for most species. We describe the ontogenetic changes in web structure ... -
Functional aspects of genital differences in Leucauge argyra and L. mariana (Araneae: Tetragnathidae)
(2013)Morphological studies have documented the tendency for male genitalia to diverge rapidly compared to other body parts in many animal groups, including spiders. But documentation of how differences in genital structures of ... -
Functional changes in web design along the ontogeny of two orb-weavers
(2017-08-01)Orb webs evolved primarily to capture prey, though they also have other functions. Recently, it has been argued that the orb web does not work as a functional unit, but instead some sections or components have presumably ... -
Fungal and Bacterial Co-Bioaugmentation of a Pesticide-Degrading Biomixture: Pesticide Removal and Community Structure Variations during Different Treatments | SpringerLink
(Springer, 2021)Biopurification systems (BPS) are employed for the treatment of pesticide-containing wastewaters. In this work, a biomixture (active core of BPS) complemented by the addition of the fungus Trametes versicolor was evaluated ... -
Fungal bioaugmentation of two rice husk-based biomixtures for the removal of carbofuran in on-farm biopurification systems
(2016-02)The ligninolytic fungus Trametes versicolor was employed in the bioaugmentation of compost- (GCS) and peat-based (GTS) biomixtures for the removal of the insecticide-nematicide carbofuran (CFN). Among several lignocellulosic ... -
Fungal communities in feces of the frugivorous bat Ectophylla alba and its highly specialized Ficus colubrinae diet
(2022)Background: Bats are important long-distance dispersers of many tropical plants, yet, by consuming fruits, they may disperse not only the plant’s seeds, but also the mycobiota within those fruits. We characterized the ... -
Fungal Communities in Sediments Along a Depth Gradient in the Eastern Tropical Pacific
(2020-11-06)Deep waters represent the largest biome on Earth and the largest ecosystem of Costa Rica. Fungi play a fundamental role in global biogeochemical cycling in marine sediments, yet, they remain little explored. We studied ...
