Nitzschia captiva sp. nov. (Bacillariophyta), the essential prey diatom of the kleptoplastic dinoflagellate Durinskia capensis, compared with N. agnita, N. kuetzingioides and other species
(Taylor & Francis Group, 2023-03-13)
Durinskia capensis is a kleptoplastic dinoflagellate species from high intertidal marine rock pools, which can use a variety of diatoms for photosynthesis. However, very few of the diatoms permit ...
Habitat and Scale Shape the Demographic Fate of the Keystone Sea Urchin Paracentrotus lividus in Mediterranean Macrophyte Communities
(Public Library of Science, 2012-04-20)
Demographic processes exert different degrees of control as individuals grow, and in species that span several habitats and
spatial scales, this can influence our ability to predict their population ...
Retos y oportunidades para la evaluación del estado ecológico en ríos temporales
(Asociación Española de Ecología Terrestre, 2024-03-06)
Los ríos temporales (RTs) son ecosistemas fluviales en los que los efectos de las perturbaciones antrópicas se mezclan con los de la propia perturbación natural que impone la temporalidad del flujo. A ...
Integrating spatiotemporal hydrological connectivity into conservation planning to protect temporary rivers
(Wiley, 2024-03-25)
1. Temporary rivers (TRs) have been largely overlooked in conservation assessments. Because TRs are such dynamic ecosystems, spatial and temporal aspects of their hydrology and ecology need to be taken ...
Diatoms as dandelions: convergent evolution in the reproductive biology of small Nitzschia species (Bacillariophyta) and its possible taxonomic consequences
(Taylor & Francis Group, 2024-03-01)
Nitzschia soratensis and N. inconspicua are two small diatoms that are extremely similar in the light microscope though separable in subtle aspects of valve and girdle ultrastructure. They are not closely ...
Description of Navicula vanseea sp. nov. (Naviculales, Naviculaceae), a new species of diatom from the highly alkaline Lake Van (Republic of Türkiye) with complete characterisation of its organellar genomes and multigene phylogeny
(Pensoft Publishers, 2024-04-08)
The current article describes Navicula vanseea sp. nov., a new species of diatom from Lake Van, a highly alkaline lake in Eastern Anatolia (Türkiye). The description is based on light and scanning ...
β-cyclodextrin polymer as tetrodotoxins scavenger in oyster extracts
(Elsevier, 2024-04-16)
Tetrodotoxins (TTXs) are potent marine neurotoxins involved in poisoning cases in humans after consumption of some marine organisms. A cell-based assay (CBA) providing toxicological information is a ...
Automated Patch Clamp for the Detection of Tetrodotoxin in Pufferfish Samples
(MDPI, 2024-04-15)
Tetrodotoxin (TTX) is a marine toxin responsible for many intoxications around the world. Its presence in some pufferfish species and, as recently reported, in shellfish, poses a serious health concern. ...
Analysing the contribution of intermittent rivers to beta diversity can improve freshwater conservation in Mediterranean rivers
(Springer, 2024-04-25)
In Mediterranean climate regions, intermittent rivers (IRs) harbor highly dynamic communities with species and trait composition changing over time and space. Simultaneously considering multiple ...
Non-perennial segments in river networks
(Springer Nature, 2023-11-23)
Non-perennial river segments — those that recurrently cease to flow or frequently dry — occur in all river networks and are globally more abundant than perennial (always flowing) segments. However, ...
