Tadpole begging reveals high quality
(2017)Parents can benefit from allocating limited resources non randomly among offspring, and offspring solicitation (i.e. begging) is often hypothesized to evolve because it contains information valuable to choosy parents. We ... -
Taxonomic Keys and Plates from The Myxomycetes
(2021-04-01)In 1969, George W. Martin and Constantine J. Alexopoulos published a remarkable work on myxomycetes. Their monograph on this group of organisms became one of the references to the taxonomy and geographical distribution of ... -
Taxonomical and functional diversity of Saprolegniales in Anzali lagoon, Iran
(2020)Studies on the diversity, distribution and ecological role of Saprolegniales (Oomycota) in freshwater ecosystems are currently receiving attention due to a greater understanding of their role in carbon cycling in various ... -
Telipogon sonia-juaniorum (Orchidaceae: Oncidiinae) a new species from Southwestern Ecuador
(2018-02-23)A new species, Telipogon sonia-juaniorum, from the semi-deciduous montane forests from Southwestern Ecuador is described and illustrated. Information about distribution, habitat, phenology, and conservation status for the ... -
Temperature and elemental sulfur shape microbial communities in two extremely acidic aquatic volcanic environments
(2021)Aquatic environments of volcanic origin provide an exceptional opportunity to study the adaptations of microbial communities to early planet life conditions such as high temperatures, high metal concentrations, and low pH. ... -
The cage test as an easy way to screen and evaluate spontaneous activity in preclinical neuroscience studies
(2021-02-17)Within behavioral neuroscience, subjects used to be randomly assigned to the experimental groups based on the premise that interindividual variability will be homogeneously distributed. However, the equivalence offered by ... -
The clerodane diterpene casearin J induces apoptosis of T-ALL cells through SERCA inhibition, oxidative stress, and interference with Notch1 signaling
(2016-01-28)T-cell acute lymphoblastic leukemia (T-ALL) is an aggressive hematologic malignancy that preferentially affects children and adolescents. Over 50% of human T-ALLs possess activating mutations of Notch1. The clerodane ... -
The contrasting roles of aquatic fungi and oomycetes in the degradation and transformation of polymeric organic matter
(2019)Studies on the ecological role of fungi and, to a lesser extent, oomycetes, are receiving increasing attention, mainly due to their participation in the cycling of organic matter in aquatic ecosystems. To unravel their ... -
The coral-associated fauna and sessile benthic reef community of Pocillopora coral colonies following transplantation in Golfo Dulce, South Pacific, Costa Rica: Composition, dynamics and succession
(2021)Coral reef restoration through coral gardening and transplantation is a valuable tool in combating the loss of critical ecosystem services and biodiversity provided by coral reefs. This study follows the changes in the ... -
The countries and languages that dominate biological research at the beginning of the 21st century
(Revista de Biolología Tropical 53 (1-2): 283-294, 2005, 2005)Traditionally, studies of scientific productivity are biased in two ways: they are based on Current Contents, an index centered in British and American journals, and they seldom correct for population size, ... -
The deepwater fishery along the Pacific coast of Costa Rica, Central America
(Lat. Am. J. Aquat. Res., 37(3): 543-554, 2009, 2009)Global catches of marine fishery resources declined during the last decades; however, there has been a trend of increasing exploitation of deepwater resources that are especially vulnerable to depletion. Such a tendency ... -
The dystrophinopathies in Costa Rica
(Rev Biol Trop 52(3), 2004, 2004)A five-years long study aiming to describe the basic genetic epidemiology of the dystrophinopathies in Costa Rica recruited 31 patients with clinical symptoms of DMD/BMD at the National Children’s Hospital (HNN). This ... -
The effect of biogeographic and phylogeographic barriers on gene flow in the brown smoothhound shark, Mustelus henlei, in the northeastern Pacific
(2015)We assessed the effects of the prominent biogeographic (Point Conception and the Peninsula of Baja California) and phylogeographic barriers (Los Angeles Region) of the northeastern Pacific on the population connectivity ... -
The effect of conspecific density, herbivory, and bamboo on seedling dynamics of a dominant oak in a Neotropical highland forest
(2019-10-17)Conspecific negative density dependence (CNDD) is one of the main mechanisms influencing diversity maintenance in tropical forests. Tropical highland forests, in contrast to most lowland forests, are commonly dominated ... -
The effect of coral reef degradation on the trophic structure of reef fishes from Bahía Culebra, north Pacific coast of Costa Rica
(2021)Fishes play numerous key ecological roles that are critical for maintaining the structure and function of coral reefs. Natural and anthropogenic disturbances can produce structural changes in coral reef habitats, which ... -
The environmental enrichment model revisited: A translatable paradigm to study the stress of our modern lifestyle
(2021-02-27)Mounting evidence shows that physical activity, social interaction and sensorimotor stimulation provided by environmental enrichment (EE) exert several neurobehavioural effects traditionally interpreted as enhancements ... -
The fishes from the Coto River basin, Pacific coast, Costa Rica
