Nutrient enrichment destabilizes aquatic food webs through synchronization within and across trophic levels

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Nutrient enrichment destabilizes ecosystems globally, but the mechanistic pathways underlying this effect in multi‐trophic communities remain unclear. To address this knowledge gap, we applied biodiversity–stability theory to multi‐trophic communities by partitioning ...

Using a B ayesian hierarchical model to improve L ake E rie cyanobacteria bloom forecasts [PDF]

, 2014
The last decade has seen a dramatic increase in the size of western Lake Erie cyanobacteria blooms, renewing concerns over phosphorus loading, a common driver of freshwater productivity.

Waterbird zoogeochemical effects shape wetland nutrient dynamics and algal communities in Laurentian Great Lakes coastal freshwater wetlands

Journal of Animal Ecology, EarlyView.
Distinct waterbird species influence nutrient cycling through guano contributions in Great Lakes coastal wetlands. Waterbird‐derived nutrients favour distinct algal communities and wetland sediments rapidly remove waterbird nutrients via biogeochemical processes.

Production of microcystins in bloom-forming cyanobacteria and their environmental fates: a review [PDF]

, 2009
The present paper introduces the recent progresses on the production mechanisms and environmental fates of microcystins -the most common toxins produced in bloom-forming cyanobacteria, in particular, Microcystis.

Characterization of Taxonomic and Functional Dynamics Associated with Harmful Algal Bloom Formation in Recreational Water Ecosystems

Toxins
Harmful algal bloom (HAB) formation leads to the eutrophication of water ecosystems and may render recreational lakes unsuitable for human use. We evaluated the applicability and comparison of metabarcoding, metagenomics, qPCR, and ELISA-based methods ...

Scientists’ warning on the global destruction of rock outcrop ecosystems

Conservation Biology, EarlyView.
Abstract Rock outcrops are geological formations that harbor a highly specialized biota adapted to harsh environmental conditions that differ from their surrounding landscapes. They are globally distributed, especially in old, highly weathered landscapes, and can function as habitat islands containing high levels of endemism and distinct evolutionary ...

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

Fisheries 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.

First Report of Cylindrospermopsin Production by Two Cyanobacteria (Dolichospermum mendotae and Chrysosporum ovalisporum) in Lake Iznik, Turkey

Toxins, 2014
Cylindrospermopsin (CYN) is a cytotoxic alkaloid produced by cyanobacteria. The distribution of this toxin is expanding around the world and the number of cyanobacteria species producing this toxin is also increasing.

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

Journal 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.
