Recomendaciones para mejorar el manejo de comederos artificiales para colibríes
(2019)El uso de comederos artificiales para alimentar a las aves es una práctica extendida y de uso generalizado principalmente en sitios turísticos, tales como hoteles de montaña, parques naturales, y jardines privados. En el ... -
Shade tolerance within the context of the successional process in tropical rain forests
(2019)Abstract: Shade tolerance (the capacity to survive and grow over long periods under shade) is a key component of plant fitness and the foundation of current theories of forest succession in tropical rain forests. It serves ... -
Behavioral changes across novelty habituation: Contextual modulation of self-grooming after a stress event
(2018-07)Grooming is a widespread behavior in the animal kingdom primarily geared towards the care of the body surface; nonetheless, other behavioral functions have been investigated and postulated. For example, rodents display ... -
Antifungal compounds
(2013-06-03)Compounds of formula (I) or formula (II), compositions and methods useful for treating and/or preventing a fungal infections are provided. wherein the substituents are as defined in the appended claims. -
Transformation of humic substances by the freshwater Ascomycete Cladosporium sp.
(2017)The ecological relevance of fungi in freshwater ecosystems is becoming increasingly evident, particularly in processing the extensive amounts of polymeric organic carbon such as cellulose, chitin, and humic substances (HS). ... -
A New Parasitic Chytrid, Staurastromyces oculus (Rhizophydiales, Staurastromycetaceae fam. nov.), Infecting the Freshwater Desmid Staurastrum sp.
(2017-08)Chytrids are a diverse group of ubiquitous true zoosporic fungi. The recent molecular discovery of a large diversity of undescribed chytrids has raised awareness on their important, but so far understudied ecological role ... -
Microplastics alter composition of fungal communities in aquatic ecosystems
(2017)Despite increasing concerns about microplastic (MP) pollution in aquatic ecosystems, there is insufficient knowledge on how MP affect fungal communities. In this study, we explored the diversity and community composition ... -
Microplastic pollution increases gene exchange in aquatic ecosystems
(2018-06)Pollution by microplastics in aquatic ecosystems is accumulating at an unprecedented scale, emerging as a new surface for biofilm formation and gene exchange. In this study, we determined the permissiveness of aquatic ... -
Aquatic fungi: targeting the forgotten in microbial ecology
(2016-06)Fungi constitute important and conspicuous components of aquatic microbial communities, but their diversity and functional roles remain poorly characterized. New methods and conceptual frameworks are required to accurately ... -
A preliminary report of aquatic hyphomycetes isolated from Anzali lagoon (Gilan province, North of Iran)
(2019)Aquatic hyphomycetes equipped with a rich array of extracellular enzymes are involved in bioremediation of anthropogenic pollutants, plastics, aromatic contaminants and petroleum hydrocarbons. The current study contributes ... -
Pilze in aquatischen Ökosystemen
(2020-06)Pilze sind phylogenetisch und funktionell vielfältige, allgegenwärtige Bestandteile fast aller Ökosysteme der Erde, einschließlich aquatischer Ökosysteme, die sich von hochmontanen Seen bis in den tiefen Ozean erstrecken. ... -
Diversity and hidden host specificity of chytrids infecting colonial volvocacean algae
(2018-05)Chytrids are zoosporic fungi that play an important, but yet understudied, ecological role in aquatic ecosystems. Many chytrid species have been morphologically described as parasites on phytoplankton. However, the majority ... -
Fungi in aquatic ecosystems
(2019-03)Fungi are phylogenetically and functionally diverse ubiquitous components of almost all ecosystems on Earth, including aquatic environments stretching from high montane lakes down to the deep ocean. Aquatic ecosystems, ... -
Highly diverse fungal communities in carbon-rich aquifers of two contrasting lakes in Northeast Germany
(2019-10)Fungi are an important component of microbial communities and are well known for their ability to decompose refractory, highly polymeric organic matter. In soils and aquatic systems, fungi play an important role in carbon ... -
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 ... -
Resistencia a desinfectantes y su relación con la resistencia a los antibióticos
(2020)Objetivo: sistematizar los principales mecanismos de acción de los desinfectantes y describir mecanismos de resistencia comunes entre biocidas y antibióticos. Métodos: se realizó una revisión bibliográfica de artículos ... -
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 ... -
The primary freshwater crabs of Guatemala (Decapoda: Brachyura: Pseudothelphusidae), with comments on their conservation status
(2016)The freshwater crabs of the family Pseudothelphusidae Ortmann, 1893 are restricted to the Neotropics and many species have an elevated risk of extinction. The majority of pseudothelphusids is considered to be data-deficient, ... -
Freshwater crabs as predators and prey: the case of Ptychophallus uncinatus Campos & Lemaitre, 1999 (Brachyura, Pseudothelphusidae) from Costa Rica, Central America
(2019)Primary freshwater crabs are an important component of the food web in aquatic ecosystems, but our knowledge about the role of these decapods as predators and as prey is far from complete. Here we report observations of ... -
Effects of temperature on the embryonic development and hatchling size of Betaeus emarginatus (Decapoda: Caridea: Alpheidae)
(2003)Betaeus emarginatus is an alpheid shrimp inhabiting rock pool environments characterized by strong fluctuations of ambient factors. Here we describe the embryonic development of B. emarginatus, and analyse the effects of ...
