Draft genome assembly and sequencing dataset of the marine diatom Skeletonema cf. costatum RCC75

Data in Brief, 2022
Diatoms (Bacillariophyceae) are a major constituent of the phytoplankton and have a universally recognized ecological importance. Between 1,000 and 1,300 diatom genera have been described in the literature, but only 10 nuclear genomes have been published

Diatom species composition and indices for determining the ecological status of coastal Mediterranean Spanish lakes

Anales del Jardín Botánico de Madrid, 2013
Diatom indices have been used and tested mainly for assessing the ecological status of rivers and deep lakes, but there are scarce studies that determine their effectiveness in shallow lakes and in coastal Mediterranean lakes.

Changing Pacific Salmon Nursery Lake Ecosystem Dynamics Over Centuries to Millennia: Insights From Sedimentary DNA Metabarcoding

Environmental DNA, Volume 8, Issue 4, July‐August 2026.
Sedimentary DNA metabarcoding tracks long‐term eukaryotic community change in Pacific salmon nursery lakes, revealing potential land‐use and climate influences on algal communities and resilience indicators. ABSTRACT Pacific salmon are keystone species in North Pacific freshwater, riparian, and marine ecosystems, but many populations have declined or ...

Intra‐Annual Chlorophyll‐a Dynamics Under Hydroclimatic Extremes Derived From a 44‐Year Baseline: Insights From a Temperate River System (Nakdong River Basin, South Korea)

Water Resources Research, Volume 62, Issue 6, June 2026.
Abstract Understanding how drought affects phytoplankton dynamics is critical for developing early warning systems. Using standardized drought indices that capture both hydrometeorological extremes, we investigated how hydrological anomalies modulate intra‐annual chlorophyll‐a (Chla) concentrations, a proxy for phytoplankton biomass, in South Korea's ...
