Occurrence of pharmaceuticals, hazard assessment and ecotoxicological evaluation of wastewater treatment plants in Costa Rica
(2020)
The continuous release of pharmaceuticals from WWTP effluents to freshwater is a matter of concern, due to their potential effects on non-target organisms. The occurrence of pharmaceuticals in WWTPs and their associated ...
On the ultraviolet behaviour of quantum fields over noncommutative manifolds
(1999-03)
By exploiting the relation between Fredholm modules and the Segal-Shale-Stinespring version of canonical quantization, and taking as starting point the first-quantized fields described by Connes' axioms for noncommutative ...
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 ...

The set of fiber-bunched cocycles with nonvanishing Lyapunov exponents over a partially hyperbolic map is open
(2018)
We prove that the set of fiber-bunched SL(2, R)-valued Hölder cocycles with nonvanishing Lyapunov exponents over a volume preserving, accessible and center-bunched partially hyperbolic diffeomorphism is open. Moreover, we ...
Microplastic ingestion by a herring Opisthonema sp. in the Pacific coast of Costa Rica
(2020-07)
Current knowledge of the presence of microplastics (MP) in marine species in tropical areas is still limited. The presence of MP was examined in the gastrointestinal content of 30 filter feeders of the herring Opisthonema ...
Movements and morphology under sexual selection: tsetse fly genitalia
(Ethology Ecology & Evolution 22: 385–391, 2010, 2010-04-17)
SHÖN (2009, Ethology Ecology & Evolution 21: 161–172) pointed out that in order
to understand the functional morphology of sexually selected structures that are used
as signaling devices in birds, it is crucial to ...
Three new species of Gliocephalotrichum causing fruit rot on different hosts from Brazil
(2020-09-18)
The genus Gliocephalotrichum (Nectriaceae), originally described as a soil-borne fungus, has been associated with postharvest diseases, especially of tropical fruits. Taxonomic studies using both morphological and molecular ...
Brachiopods, sipunculans, enteropneusts and metals from two estuarine tidal flats, Pacific, Costa Rica
Braquiópodos, sipuncúlidos, enteropneustos y metales en dos planicies estuarinas de marea, Pacífico, Costa Rica.
(2016-09)
Reports on the abundances and on metal concentrations in intertidal estuarine invertebrates from the
Eastern Tropical Pacific are rare. Thus, the objectives of this report are to make accessible data on the abundances

Behavioural responses of reptiles to visitors of protected areas in Costa Rica
(2016)
Tourists can have a strong impact on the behaviour of wild animals, modifying
foraging strategies, diet and habitat use, increasing stress, and altering communication
and escaping behaviour. Such behavioural changes have ...
