Photobiochemical changes in Chlorella g120 culture during trophic conversion (metabolic pathway shift) from heterotrophic to phototrophic growth regime
(2020)
Physiological and photobiochemical changes and growth in the heterotrophic strain Chlorella vulgaris g120 were studied during
trophic conversion from heterotrophic to phototrophic growth regime. After the exposure of the ...
Avistamientos de Orcinus orca (Linnaeus, 1758) (Cetartiodactyla: Odontoceti: Delphinidae) en el Pacífico costarricense (1990-2020)
Sightings of Orcinus orca (Linnaeus, 1758) (Cetartiodactyla: Odontoceti: Delphinidae) in the Costa Rican Pacific (1990-2020)
(2021-09)
Las orcas son cetáceos poco estudiados en el trópico, y sus desplazamientos por aguas costarricenses han sido escasamente abordados. Son animales de gran importancia ecológica debido a su rol como depredadores top, y ...
Life cycle and in vitro sporulation dynamics of Corinectria constricta, the causal agent of Pinus radiata stem canker, in Chile
(2020-04-07)
In 2008, a canker disease caused by the fungus Corinectria constricta was detected in southern Chile. The causal agent was previously identified as Neonectria fuckeliana (now Corinectria fuckeliana), which has been associated ...
Dry-season leaf flushing of Enterolobium cyclocarpum (ear-pod tree): above- and belowground phenology and water relations
(2007-11)
Above- and belowground phenology and water relations of Enterolobium cyclocarpum Jacq. trees in the dry
forest of Santa Rosa National Park, Costa Rica were studied during two consecutive phenological cycles, from November ...
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). ...
