Lake Superior Supports Novel Clusters of Cyanobacterial Picoplankton [PDF]
Applied and Environmental Microbiology, 2007 ABSTRACTVery little is known about the biodiversity of freshwater autotrophic picoplankton (APP) in the Laurentian Great Lakes, a system comprising 20% of the world's lacustrine freshwater. In this study, the genetic diversity of Lake Superior APP was examined by analyzing 16S rRNA gene andcpcBAPCR amplicons from water samples. By neighbor joining, the

Dynamics of auto- and heterotrophic picoplankton and associated viruses in Lake Geneva [PDF]
, 2014 Microbial dynamics have rarely been investigated in Lake Geneva, known as the largest lake in western Europe. From a 5-month survey, we report dynamic patterns of free-living virus, bacteria and small phytoplankton abundances in response to a variety of ...

Aquaculture, 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 ...

Natural recolonization of a productive tropical pond : day to day variations in the photosynthetic parameters [PDF]
, 1991 Chlorophyll pigments (CHL), primary productivity (PP) and particulate nitrogen (Np) in relation to several environmental factors were monitored during planktonic colonization of an aquaculture pond (Layo, Côte d'Ivoire).

Global Biogeochemical Cycles, Volume 40, Issue 4, April 2026.Abstract Phytoplankton size classes (PSCs) and Phytoplankton functional types (PFTs) determine many fundamental biogeochemical processes including nutrient uptake, energy transfer through marine food webs, ocean carbon export, and gas exchange with the atmosphere. Discerning the causes of spatio‐temporal variability of PSCs is a scientific priority for

An ecological assessment of the trophic structure of York Pond in Coos County Milan, NH [PDF]
, 2004 We examined the physical, chemical and biological properties of York Pond in Coos County Milan, NH as a part of a 6-lake study. Chemical and physical characteristics measured included: total phosphorus and nitrogen, turbidity, light profiles with Secchi ...

Size-partitioned phytoplankton carbon and carbon-to-chlorophyll ratio from ocean colour by an absorption-based bio-optical algorithm [PDF]
, 2017 The standing stock of phytoplankton carbon is a fundamental property of oceanic ecosystems, and of critical importance to the development of Earth System models for assessing global carbon pools and cycles.

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 4, April 2026.Abstract This study presents a new physical‐biogeochemical simulation of the Pacific Ocean that resolves mesoscale dynamics and explicitly includes tidal forcing. The primary objective is to develop and document a modeling framework that serves both as a detailed record of model configuration and forcing preparation, and as a reference for future ...

The response of marine picoplankton to ocean acidification [PDF]
Environmental Microbiology, 2012 Summary Since industrialization global CO 2 emissions have increased, and as a consequence oceanic pH is predicted to drop by 0.3–0.4 units before the end of the century – a process coined ‘ocean acidification’.

The Effects of Alewife on the Zooplankton Community in Townhouse Pond [PDF]
, 2009 The purpose of this study was to determine what plankton species was more dominant in Townhouse Pond and what effects predation has on the food web. Plankton size is important when determining pelagic food web structure.
