Physiological and transcriptomic evidence for a close coupling between chloroplast ontogeny and cell cycle progression in the pennate diatom Seminavis robusta [PDF]

, 2008
Despite the growing interest in diatom genomics, detailed time series of gene expression in relation to key cellular processes are still lacking. Here, we investigated the relationships between the cell cycle and chloroplast development in the pennate ...

ChloroScan: Recovering Plastid Genome Bins From Metagenomic Data

Molecular Ecology Resources, Volume 26, Issue 3, April 2026.
ABSTRACT Genome‐resolved metagenomics has contributed greatly to discovering prokaryotic genomes. When applied to microscopic eukaryotes (protists), challenges such as the high number of introns and repeat regions found in nuclear genomes have hampered the mining and discovery of novel protistan lineages.

Effects of different types of fertilizers on plankton productivity in earthen ponds [PDF]

, 2003
Three fertilizer types (NPK, Super-phosphate and cow dung) were applied at two levels (Low, 0.3 kg/25m super(2)/2weeks and High, 0.7kg/25 m super(2)/2weeks) to 12 ponds with two ponds serving as control.

Phosphorus Acquisition Strategies Among Phytoplankton and Free‐Living Bacterial Communities in the Baltic Proper

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
Phosphorus is a key element for cellular functions and poses significant challenges for planktonic microbial communities under limited availability. Metagenomics highlighted that heterotrophic bacteria predominantly relied on phosphate scavenging while eukaryotic phytoplankton primarily utilized membrane remodelling to cope with limited phosphorus ...

High-Up: A Remote Reservoir of Microbial Extremophiles in Central Andean Wetlands [PDF]

, 2015
The Central Andes region displays unexplored ecosystems of shallow lakes and salt flats at mean altitudes of 3700 m. Being isolated and hostile, these so-called “High-Altitude Andean Lakes” (HAAL) are pristine and have been exposed to little human ...

Effects of River Beads on Algal Nutrient Limitation Following Severe Wildfire

Freshwater Biology, Volume 71, Issue 4, April 2026.
ABSTRACT Severe wildfires often increase inputs of nitrogen (N) and phosphorus (P) to streams, which can alter nutrient limitation and primary production of benthic algae. Changes in nutrient limitation, however, vary over space and time due to physical and biological factors.

NATURAL DIET OF BARBEL BARBUS PELOPONNESIUS (VALENCIENNES, 1842) FROM THE SAVA RIVER [PDF]

Croatian Journal of Fisheries, 2007
The barbel population (Barbus peloponnesius) was studied in the Sava River at Medsave from July to October 2001. The main objective of the study was to obtain data on diet composition of this species in natural biotopes with relation to food availability

Characterization of a trimeric light-harvesting complex in the diatom Phaeodactylum tricornutum built of FcpA and FcpE proteins [PDF]

, 2010
Fucoxanthin chlorophyll proteins (Fcps), the light-harvesting antennas of heterokont algae, are encoded by a multigene family and are highly similar with respect to their molecular masses as well as to their pigmentation, making it difficult to purify ...

Cold comfort for change: Stream mats as biological indicators of ecosystem processes in the McMurdo Dry Valleys, Antarctica

Journal of Phycology, Volume 62, Issue 2, Page 261-292, April 2026.
Abstract Glacier‐fed streams (GFSs) make ideal systems for studying climate‐related changes. Some of the best‐studied GFSs are found in the McMurdo Dry Valleys (MDVs) of Antarctica, one of the Earth's coldest and driest deserts. Despite their harsh and isolated nature, MDV GFSs represent an oasis of life in a landscape visually devoid of it, with ...
