Myxomycetes within ecotones in temperate and tropical forests
Mixomicetes en ecotonos forestales de bosques templados y tropicales
Mixomicetos em ecótonos florestais de bosques temperados e tropicais
(2021)
Ecotones are interesting portions of forests where microorganisms can be studied for monitoring and
diversity purposes. Given the faster life cycle of these organisms, their study in such a context is important
to develop ...
Detection of a synthetic sex steroid in the American crocodile (Crocodylus acutus): Evidence for a novel environmental androgen
(2017-08)
Endocrine-disrupting contaminants (EDC's) are well known to alter sexual differentiation among vertebrates via estrogenic effects during development, particularly in organisms characterized by
temperature-dependent sex ...
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 ...

Gastric cancer in the era of immune checkpoint blockade
(2019-09-24)
Gastric cancer (GC) is one of the most important malignancies worldwide because of its high incidence and mortality. The very low survival rates are mainly related to late diagnosis and limited treatment options. GC is the ...
Relative Importance for Lincoln’s Sparrow (Melospiza lincolnii) Occupancy of Vegetation Type versus Noise Caused by Industrial Development
(2022)
Anthropogenic noise can create an acoustic environment detrimental for animals that communicate using acoustic signals. Currently, most studies of noise and wildlife come from traffic noise in cities. Less is known about ...
Role of arbuscular mycorrhizal symbiosis in remediation of anthropogenic soil pollution
(2021-05)
Agricultural and industrial activity generates high concentrations of organic and inorganic pollutants, many of which are incorporated into the trophic chain, affecting ecosystems. There are several strategies for the ...

Ammonium and phosphate removal using batch laboratory cultures by microalgae and cyanobacteria isolated from Costa Rica water bodies
Remoción de amonio y fosfato en cultivos de laboratorio con microalgas y cianobacterias aisladas de cuerpos de agua de Costa Rica
(2018)
This research analyzed three green microalgae (Scenedesmus sp., Chlamydomonas sp., and Chlorella
sp.) and two cyanobacteria (Synechocystis sp. as unicellular strain and Nostoc sp. as filamentous strain) native
from Costa ...
