Key to the species of the genus Scleria (Cyperaceae) in Costa Rica based on the morphology of achenes
(2016)
We described the achenes of 21 species of the genus Scleria reported in Costa Rica using 16 morphological characters and developed a key based only on achene characteristics. Specimens deposited in herbaria in Costa Rica ...
Morphological and ecological variation of a tropical anoline lizard: are agonistic interactions shaping ecomorphological relationships?
(2018)
Ecologists have long been intrigued by which factors influence habitat use by an organism and how communities are structured. However, the links between habitat preferences, morphology, biotic interactions and community ...
Variation of bacterial communities along the vertical gradient in Lake Issyk Kul, Kyrgyzstan
(2021-02-04)
We explored the diversity and community composition of bacteria along a vertical gradient in Lake Issyk Kul, Kyrgyzstan, one of the world's largest and deepest brackish lakes. We identified 4904 bacterial amplicon sequence ...
A Review of Breeding Systems in the Pineapple Family (Bromeliaceae, Poales)
(2023-07-05)
Breeding systems play an essential role in plant sexual reproduction and influence speciation and extinction processes. However, our understanding of the breeding systems for particular neotropical angiosperm families is ...
New insights into the molecular phylogeny of the swimming crabs of the genera Portunus Weber, 1795 and Achelous De Haan, 1833 (Brachyura: Portunidae) of the Americas
(2018)
Earlier studies of swimming crabs (family Portunidae) in the Americas suggested polyphyly of Portunus Weber, 1795. Our previous molecular analyses provided evidence for a subdivision of the genus, resulting in a reassignment ...
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). ...
Is black plumage an adaptation to high elevations in a cosmopolitan bird genus?
(2019)
Black plumage is expected to absorb and retain more heat and provide better protection against UV radiation compared with lighter plumages. Black plumage is common in species of the genera Turdus and Platycichla that inhabit ...

Harmful blooms by noxious dinoflagellates in the Pacific coast of Costa Rica
(Hidrobiológica. Vol. 18 No. 1 • 2008, 2008)
Desde 1979 se han reportado florecimientos de especies de microalgas nocivas (FAN) en la costa Pacífica de Costa Rica, reconociéndose hasta el 2005 al menos 13 taxa de dinoflagelados. En años recientes estos fenómenos se ...
Sounds in Melipona costaricensis (Apidae: Meliponini): effect of sugar concentration and nectar source distance
(Apidologie 33 (2002) 375–388, 2002)
The principal finding presented here is that Melipona costaricensis produces sounds that vary significantly
in relation to varying sugar concentrations. Several components of the sounds produced, during the
bees’stay ...
