The Effects of Nutrient Additions on Kokanee in Dworshak Reservoir, Idaho

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT We investigated the effects of whole reservoir nitrogen (N) addition on kokanee growth in Dworshak Reservoir, Idaho. We hypothesized that N addition would improve the growth of kokanee (Oncorhynchus nerka) at a given level of abundance by increasing the availability of Daphnia, an important food source.

Migration of Net Phytoplankton and Zooplankton in Mendum’s Pond, New Hampshire [PDF]

open access: yes, 2006
The study examines the vertical distribution and migratory behavior of net phytoplankton and zooplankton of Mendum’s Pond in Barrington, N.H. The cyanobacteria, Microcystis and Aphanocapsa were the dominant net phytoplankton in this lake.

Pejerrey (Odontesthes bonariensis) Under Siege: Main Infectious Diseases and Their Role in Aquaculture and Wild Populations Amidst Environmental Change

open access: yesJournal of Fish Diseases, Volume 48, Issue 4, April 2025.
ABSTRACT The pejerrey (Odontesthes bonariensis) is a key species for recreational and commercial fisheries in Argentina and holds significant aquaculture potential. It has been introduced to various countries worldwide, including Japan, where intensive aquaculture has developed.

Spectral signatures of photosynthesis I: Review of Earth organisms

open access: yes, 2007
Why do plants reflect in the green and have a 'red edge' in the red, and should extrasolar photosynthesis be the same? We provide: 1) a brief review of how photosynthesis works; 2) an overview of the diversity of photosynthetic organisms, their light ...

Key metabolites secreted by Chlorella vulgaris alleviate salt stress in soybean seedlings

open access: yesJournal of Integrative Plant Biology, EarlyView.
Chlorella vulgaris secretes exosome‐derived linolenic acid and inosine, which alleviate salt stress and enhance salt tolerance in soybean seedlings by activating stress‐responsive signaling networks. ABSTRACT Soil salinization is a major abiotic stress factor that reduces soybean production.

Bridging the gap between omics and earth system science to better understand how environmental change impacts marine microbes [PDF]

open access: yes, 2015
The advent of genomic-, transcriptomic- and proteomic-based approaches has revolutionized our ability to describe marine microbial communities, including biogeography, metabolic potential and diversity, mechanisms of adaptation, and phylogeny and ...

Phytoplankton growth and potential cyanotoxin production differ in response to nitrogen and phosphorus amendments in late summer communities from Kabetogama Lake (Minnesota, United States)

open access: yesJournal of Phycology, EarlyView.
Abstract Cyanotoxins such as microcystin (MC), cylindrospermopsin, and saxitoxin are secondary metabolites that are rich in nitrogen (N). Most cyanobacteria grow best on reduced inorganic N (ammonium, NH4), but when NH4 is absent, cyanobacteria can activate physiological pathways to process other N forms (e.g., nitrate; NO3).

Inorganic Carbon Acquisition and Photosynthetic Metabolism in Marine Photoautotrophs: A Summary

open access: yesPlants
The diffusive availability of CO2 for photosynthesis is orders of magnitude lower in water than in air. This, and the low affinity of ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) for CO2, implies that most marine photoautotrophs ...

Bacterial community profiles and Vibrio parahaemolyticus abundance in individual oysters and their association with estuarine ecology [PDF]

open access: yes, 2017
Oysters naturally harbor the human gastric pathogen Vibrio parahaemolyticus, but the nature of this association is unknown. Because microbial interactions could influence the accumulation of V. parahaemolyticus in oysters, we investigated the composition
