An Investigation into changes in the phytoplankton community in Loch Creran, a Scottish sea loch [PDF]

open access: yes
Short term and irregular sampling in Loch Creran over recent decades suggested that changes may be occurring in the phytoplankton community in the loch. This study sought to confirm this suggestion. After instigating a regular sampling regime during 2008

Latitudinal phytoplankton distribution and the neutral theory of biodiversity [PDF]

open access: yes, 2012
Aim Recent studies have suggested that global diatom distributions are not limited by dispersal, in the case of both extant species and fossil species, but rather that environmental filtering explains their spatial patterns.

Prospects of multipurpose biomonitoring for fisheries assessment based on environmental nucleic acids

open access: yesJournal of Fish Biology, EarlyView.
Abstract Methods using environmental nucleic acids have become highly effective for monitoring aquatic biodiversity, with an array of suitable use cases, including metrics for fisheries assessment. Traditional methods for assessing fish populations often rely on invasive techniques with limited spatial and temporal coverage.

Spatial and temporal variation of the phytoplankton community in a section of the Iguaçu River, Paraná, Brazil

open access: yesBrazilian Journal of Biology
The work aimed to show variations in the composition and structure of the phytoplankton community at high water and low water in Iguaçu Falls, Iguaçu River and to examine the influence of these waterfalls and environmental variables on the community ...

Seasonal succession of free-living bacterial communities in coastal waters of the Western Antarctic Peninsula

open access: yesFrontiers in Microbiology, 2016
The marine ecosystem along the Western Antarctic Peninsula (WAP) undergoes a dramatic seasonal transition every spring, from almost total darkness to almost continuous sunlight, resulting in a cascade of environmental changes, including phytoplankton ...

Plankton vertical migrations - Implications for the pelagic ecosystem

open access: yes, 2011
Habitat selection is an important behavior of many organisms. The direction and strength of this behavior is often characterized as a result of a trade off between predator avoidance and obtaining resources. A characteristic example of this trade off may

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.

On the community and ecosystem level consequences of warming

open access: yes, 2010
PhDThe carbon cycle modulates climate change, via the regulation of atmospheric CO2, and it represents one of the most important ecosystem services of value to humans.

Novel Hydrurus species (Chrysophyceae) and their adaptations to high‐altitude European and Arctic snowfields

open access: yesJournal of Phycology, EarlyView.
Abstract Colored snow caused by green algae (Chlorophyceae) is well known, but melting snowpacks can also harbor golden‐brown blooms consisting of Chrysophyceae. We collected 14 samples of cryoflora in the Austrian and Swiss Alps, the High Tatras in Slovakia, and in Arctic Svalbard. Eight laboratory unicellular flagellated strains were established from

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).
