Primeros registros de dinoflagelados de la Reserva de la Biosfera Isla Guadalupe , Baja California, México

Polibotánica
La Reserva de la Biosfera Isla Guadalupe (RBIG), se localiza a 241 km de la costa occidental de México y, por ende, uno de los territorios insulares más distante del país. Por lo tanto, el estudio de su biodiversidad en el contexto biogeográfico resulta

Spliced leader RNAs, mitochondrial gene frameshifts and multi-protein phylogeny expand support for the genus Perkinsus as a unique group of alveolates. [PDF]

PLoS ONE, 2011
The genus Perkinsus occupies a precarious phylogenetic position. To gain a better understanding of the relationship between perkinsids, dinoflagellates and other alveolates, we analyzed the nuclear-encoded spliced-leader (SL) RNA and mitochondrial genes,

Extending monitoring with sediment archive approaches: Comparison of biomonitoring, metabarcoding, and biomarkers to assess past phytoplankton dynamics

Limnology and Oceanography: Methods, Volume 23, Issue 8, Page 578-593, August 2025.
Abstract Sedimentary archives can provide valuable insights into the study of anthropogenic impacts on marine and limnic ecosystems over centennial and millennial timescales, potentially extending the temporal breadth of observation‐based biomonitoring.

DNA Metabarcoding Focusing on Eukaryote Communities on Langhovde Glacier, East Antarctica

Environmental Microbiology Reports, Volume 17, Issue 4, August 2025.
Based on comprehensive 18S rRNA gene analysis, this study characterises the eukaryotic communities inhabiting the supraglacial environments of Langhovde Glacier, East Antarctica, in relation to the associated aquatic chemistry. Genetic differences between organisms found in the surrounding ice‐free areas and those in distant snow and ice fields are ...

Freshwater Discharge and Salinity Drive Taxonomic and Functional Turnover of Microbial Communities in a Turbid Macrotidal Estuary

Environmental Microbiology Reports, Volume 17, Issue 4, August 2025.
Seasonal shifts in microbial community composition in the Schelde estuary are controlled by the interaction between freshwater discharge and marine intrusion. However, these recurrent annual patterns can be disrupted by extreme precipitation events.
