High numbers of Trichodesmium and diazotrophic diatoms in the southwest Indian Ocean [PDF]

, 2009
We observed high cell numbers of large (>50?m) nitrogen-fixing phytoplankton to the south and to the east of Madagascar in February 2005. The distribution of the diazotrophic taxa we found was markedly different: Trichodesmium was most abundant (500 ...

Mapping Phytoplankton and Algal Blooms With a Novel Multisensor Water Index

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Multispectral satellite imageries (MSIs) are strong enough to delineate features of interest by suppressing others. The water index is a method applied to delineate the water features by combining the multispectral band images.

Wildfire in the Surrounding Landscape Alters Limnological Conditions and Plankton Communities in a Tropical Reservoir

International Review of Hydrobiology, Volume 111, Issue 2, December 2026.
ABSTRACT Wildfires are becoming increasingly frequent and severe as a consequence of climate change. Their impacts on terrestrial ecosystems and on the atmosphere include the release of gases and ash, as well as enhanced soil susceptibility to erosion and the downstream transport of materials into aquatic systems.

Short term changes in polysaccharide utilisation during a spring phytoplankton bloom on Helgoland

, 2019
Spring phytoplankton blooms contribute significantly to global marine primary production. A large fraction of the bloom derived organic matter is available to heterotrophic bacteria in the form of polysaccharides.

Atmospheric Control of Deep Chlorophyll Maximum Development

Geosciences, 2019
The evolution of the near-surface phytoplankton bloom towards a Deep Chlorophyll Maximum (DCM) in mid-latitudes and subpolar regions of the global ocean is a well-known biological feature.

Translocated Clam Retention and Effects on Ecosystem Functions Across a Gradient of Environmental Stress

New Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 4, December 2026.
Estuarine ecosystems are experiencing increasing land‐derived stress, bringing sediments, excess nutrients and contaminants. Once degraded, disturbed soft sediment ecosystems can take years to recover because long‐lived, functionally important species that aid recovery are lost.

The influence of viral infection on a plankton ecosystem undergoing nutrient enrichment [PDF]

, 2010
It is increasingly recognised that viruses are a significant active component of oceanic plankton ecosystems. They play an important role in biogeochemical cycles as well as being implicated in observed patterns of species abundance and diversity.

Seascape genomics reveals high genetic diversity and apparent panmixia in endemic Southern Ocean phytoplankton

Limnology and Oceanography Letters, Volume 11, Issue 6, November 2026.
Abstract The adaptive potential and resilience of cold‐adapted phytoplankton to climate change have the potential to impact polar marine food webs and global biogeochemical cycles. Two central but poorly constrained facets of adaptive potential in polar phytoplankton are standing genetic diversity and its spatial structure. Here, we partially sequenced

Experimental Assessment of Epipelon Responses to Phosphorus Limitation in a Eutrophic Lake

Ecological Research, Volume 41, Issue 6, November 2026.
We evaluated the responses of epipelic algal and cyanobacterial communities to increasing phosphorus limitation in the water column under eutrophic conditions. Nitrogen enrichment increased the N:P ratio and intensified phosphorus limitation in the water column, promoting changes in community composition. The greater contribution of cyanobacteria (e.g.,

A Fishery‐Dependent CPUE‐Based Proxy Index for Juvenile Japanese Anchovy (Engraulis japonicus) Recruitment Variability in Southeastern Korea: Associations With Lagged Climate‐Ocean Conditions

Fisheries Oceanography, Volume 35, Issue 6, Page 813-823, November 2026.
ABSTRACT We developed and evaluated a fishery‐dependent catch‐per‐unit‐effort (CPUE)‐based proxy index for juvenile Japanese anchovy (Engraulis japonicus) recruitment‐related variability in the southeastern coastal waters of Korea. The proxy was constructed from bimonthly CPUE of the smallest juvenile size class (20–40 mm) in the anchovy drag‐net ...
