Seagrasses of Costa Rica: from the mighty Caribbean to the dynamic meadows of the Eastern Tropical Pacific
(2018)
Seagrass meadows are declining worldwide, mostly attributed to anthropogenic disturbances. Understanding the dynamics of these meadows is urgent in order to establish adequate management and conservation strategies. Here, ...
Semigrupos dinámicos y las ecuaciones de Bloch en sistemas abiertos finitos
(1981-07)
En la Mecánica Estadística sin equilibrio, se suele derivar las ecuaciones de transporte de un sistema abierto del requisito que tal sistema forma parte de un gran sistema dinámico conservativo cerca del equilibrio. Las ...
Critical Assessment of pH-Dependent Lipophilicity Profiles of Small Molecules: Which One Should We Use and In Which Cases?
(2023-10-03)
Lipophilicity is a physicochemical property with wide relevance in drug design, computational biology, food, environmental and medicinal chemistry. Lipophilicity is commonly expressed as the partition coefficient for neutral ...
Population structure and genetic connectivity 1 of the scalloped hammerhead shark (Sphyrna lewini) across nursery grounds from the Eastern Tropical Pacific: implications for management and conservation
Genetic connectivity of an endangered shark across nursery areas from the Eastern Tropical Pacific
(2022-09)
Defining demographically independent units and understanding gene flow between
them is essential for managing and conserving exploited populations. The scalloped
hammerhead shark, Sphyrna lewini , is a coastal semi-oceanic ...
Wind creates crown shyness, asymmetry, and orientation in a tropical montane oak forest
(2020)
In a cloud forest dominated by Quercus costaricensis, the gap size between the crowns was consistent and crowns were asymmetrical, being elongated perpendicular to the prevailing wind direction. A wind storm of 20 m/s ...
Decisions during courtship by male and female medflies (Diptera, Tephritidae): Correlated changes in male behavior and female acceptance criteria in mass-reared flies
(Florida Entomologist 85(1):14-31. 2002, 2002-12)
Análisis de más de 300 cortejos video-grabados de moscas del Mediterráneo silvestres y criadas en masas de Costa Rica demostraron que la tendencia de los machos y las hembras de alinearse cara a cara el uno frente al otro ...
New combinations and synonyms in the Maxillariinae (Orchidaceae)
(2013)
Twelve orchid species previously described in the genus Maxillaria are transferred to Heterotaxis, Inti, Pityphyllum, and Sauvetrea. In addition, 19 new heterotypic synonyms in Maxillariinae are presented; these and a few ...
Integrating chytrid fungal parasites into plankton ecology: research gaps and needs
(2017-06-15)
Chytridiomycota, often referred to as chytrids, can be virulent parasites with the potential to inflict mass mortalities on hosts, causing e.g. changes in phytoplankton size distributions and succession, and the delay or ...
Reproductive Strategies and Colonizing Ability of Two Sympatric Epiphytic Bromeliads in a Tropical Premontane Area
(2006)
Predispersal characteristics that affect the reproductive success in plants may influence their colonizing ability. We evaluated this hypothesis in two sympatric epiphytic bromeliads in Costa Rica, Guzmania monostachia and ...
