Macroscale abundance patterns of hydromedusae in the temperate Southwestern Atlantic (27º-56º S) [PDF]

open access: yes, 2019
Gelatinous organisms are crucial components of marine ecosystems and some species imply social and economic consequences. However, certain geographic areas, such as the temperate Southwestern Atlantic (SWA, 27 - 56 S), remain understudied in terms of ...

AutoChamber: A broadly accessible 3D‐printed floating chamber to automate measurements of greenhouse gas emissions from surface waters

open access: yesMethods in Ecology and Evolution
Fresh waters provide environmental conditions that favour microbial CO2 and CH4 production, leading to the release of large quantities of greenhouse gases (GHG) to the atmosphere.

Identification of Plankton on Fish Pond of Oreochromis niloticus Infected by Viral Nervous Necrosis

open access: yesResearch Journal of Life Science, 2016
The purpose of study is to determine the type of plankton found in cultivation pond of nile tilapia infected by VNN. The method is to identify the plankton in the water pond and testing the VNN that infects nile tilapia related to plankton eaten using ...

Biological hot spots and the accumulation of marine dissolved organic matter in a highly productive ocean margin [PDF]

open access: yes, 2016
Concentrations of dissolved organic carbon (DOC) and major biochemicals (amino acids and carbohydrates) were measured during five cruises (2009–2010) to the Louisiana margin in the northern Gulf of Mexico.

Photosynthesis of phytoplankton of the Klyaz'minsk reservoir. [Translation from: Trudy VI Soveshchaniya po Problemem Biologii Vnutrennikh Vod. Moscow, Izd. Akad. Nauk SSSR. pp. 273-287, 1955] [PDF]

open access: yes, 1955
The processes of synthesis and destruction of organic matter play an important role in the ”self-cleaning” of reservoirs. The basic problem of this investigation consists of the role of phytoplankton in enriched waters of the Klyaz'minsk water reservoir ...

Chaotic advection of reacting substances: Plankton dynamics on a meandering jet [PDF]

open access: yes, 1999
We study the spatial patterns formed by interacting populations or reacting chemicals under the influence of chaotic flows. In particular, we have considered a three-component model of plankton dynamics advected by a meandering jet.

Extreme summer storm elicits shifts in biogeochemistry, primary productivity, and plankton community structure in a large‐scale lake enclosure experiment

open access: yesLimnology and Oceanography Letters
Climate change increases the magnitude and frequency of extreme weather events. This includes severe summer storms altering lake physical structure, biodiversity and ecosystem processes.

Assessment of Pelagic Food Webs in Mendums Pond, NH [PDF]

open access: yes, 2009
This study focused on the relationship between plankton in Mendums Pond, NH. A grazing experiment was conducted to determine the effect of zooplankton on the phytoplankton population.

Coastal Eukaryotic Plankton Diversity of the Southern Adriatic as Revealed by Metabarcoding

open access: yesDiversity
Plankton studies serve as a basis for marine ecosystem research, but knowledge of marine plankton is still incomplete due to its extreme taxonomic and functional complexity.

The continuous plankton recorder survey: A long-term, basin-scale oceanic time series [PDF]

open access: yes
In the 1920s, before the advent of echo sounders, fishery biologists were greatly concerned with assisting the fisherman to locate schools of pelagic fish.
