Increased prey choice is associated with higher kleptoplastidic reliance in Mesodinium ciliates

open access: yesJournal of Phycology, EarlyView.
Abstract Kleptoplastidic organisms display varying levels of reliance on stolen plastids, with some lineages evolving complex strategies for plastid (and other organelle) integration into metabolism. More complex methods of plastid integration typically coincide with greater prey specialization, but it remains unclear whether or how kleptoplastidic ...

Zoocoenological state of microhabitats and its seasonal dynamics in an aquatic macroinvertebrate assembly (Hydrobiological case studies on lake Balaton, No. 1.) [PDF]

open access: yes, 2005
In the years 2002, 2003 and 2004 we collected samples of macroinvertebrates on a total of 36 occasions in Badacsony bay, in areas of open water (in the years 2003 and 2004 reed-grassy) as well as populated by reed (Phragmites australis) and cattail ...

Impact of Feeding Strategies on Trophic Dynamics, Growth Performance and Sustainability of Nile Tilapia in Semi‐Intensive Aquaculture Systems

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT Feed costs and limited knowledge of feeding strategies are a major constraint to the sustainability of semi‐intensive Nile tilapia aquaculture systems in sub‐Saharan Africa. In semi‐intensive systems, Nile tilapia (Oreochromis niloticus) utilizes natural pond production and supplemental feed, but their relative contributions to growth remain ...

Pseudomonas aeruginosa aggregation and Psl expression in sputum is associated with antibiotic eradication failure in children with cystic fibrosis

open access: yesScientific Reports, 2022
We previously demonstrated that P. aeruginosa isolates that persisted in children with cystic fibrosis (CF) despite inhaled tobramycin treatment had increased anti-Psl antibody binding in vitro compared to those successfully eradicated.

High nitrate to phosphorus regime attenuates negative effects of rising pCO2 on total population carbon accumulation [PDF]

open access: yes, 2012
The ongoing rise in atmospheric pCO2 and consequent increase in ocean acidification have direct effects on marine calcifying phytoplankton, which potentially alters carbon export. To date it remains unclear, firstly, how nutrient regime, in particular by

Hypolimnetic anoxia in oligotrophic lakes and its effects on nutrient supply and phytoplankton communities

open access: yesEcosphere, Volume 17, Issue 4, April 2026.
Abstract Low concentrations of dissolved oxygen (DO) in hypolimnetic waters are becoming more common and could affect nutrient supplies available to phytoplankton communities in meso‐ and eutrophic lakes. We examined the connections among hypolimnetic DO, nutrient concentrations, and phytoplankton communities in 26 oligotrophic lakes in the Kawartha ...
