Two new species of Scheloribatidae (Acari, Oribatida) from Costa Rica
(2015-06-30)
Two new species of oribatid mites of the family Scheloribatidae, Scheloribates costaricensis sp. nov. and Perscheloribates paraluminosus sp. nov., are described from leaf litter of secondary forest in Costa Rica. Scheloribates ...
First characterization of seagrasses at S´amara Bay, Pacific coast of Costa Rica
(2022)
Seagrasses are found at limited locations in the Eastern Tropical Pacific (ETP). Here, we provide the first characterization of seagrasses at Sámara Bay, on the northern Pacific coast of Costa Rica. Sampling was carried ...
Mapping estuarine vegetation using satellite imagery: The case of the invasive species Baccharis halimifolia at a Natura 2000 site
(2019-02)
The invasive shrub Baccharis halimifolia is a threat to the environmental health of many estuarine protected areas
throughout Europe. It displaces saltmarsh vegetation and creates monospecific stands that diminish the ...
A mathematical model with nonlinear relapse: conditions for a forward-backward bifurcation
(2023)
We constructed a Susceptible-Addicted-Reformed model and explored the dynamics of nonlinear relapse in the Reformed population. The transition from susceptible considered at-risk is modeled using a strictly decreasing ...
Diseño y caracterización de un enfriador de átomos de tipo “desacelerador Zeeman”
(2016)
Nosotros presentamos un método que utiliza simultáneamente dos modelos matemáticos, con el objetivo de optimizar el diseño de un desacelerador Zeeman, con miras a la implementación de átomos ultrafríos a la física del ...
Sweet as Vanilla hartii: Evidence for a nectar-rewarding pollination mechanism in Vanilla (Orchidaceae) flowers
(2023-05-01)
Little is known about the pollination mechanisms of species belonging to the genus Vanilla (Orchidaceae). Both autonomous self-pollination and animal-mediated pollination mechanisms seem to exist amongst the Vanilla species, ...
Cálculo de la evaporación en Costa Rica mediante el método FAO-56
(2014-06)
Con el método FAO-56 se calcula la evapotranspiración de referencia para un cultivo de referencia “De una altura de 0,12m con una resistencia superficial de 70 s/m y un albedo de 0,23”. Posteriormente se calcula el coeficiente ...
Lyapunov exponents of probability distributions with non-compact support
(2020)
A recent result of Bocker–Viana asserts that the Lyapunov exponents of compactly supported probability distributions in GL(2, R) depend continuously on the distribution. We investigate the general, possibly concompact ...
Modelos estadísticos para la interacción océano-atmósfera
(2020)
La presente investigación tiene como objetivo modelar la interacción del océano -atmósfera
utilizando la relación entre la Oscilación del Sur y los eventos El Niño -La Niña como un
sistema de ...
