Harmful algal blooms and Vibrio spp. association in fishing and marine farming areas of mollusk bivalves in Sechura and Pisco bays, Peru

Revista Peruana de Biología, 2017
Between February 2010 and May 2014, 22 surveys in Pisco and 16 in Sechura were conducted; both are major areas for shellfish production and mariculture in Peru.

Nesting ecology of an ice‐associated seabird, Kittlitz's murrelet, at the northern edge of its range

Wildlife Society Bulletin, EarlyView.
We studied the Kittlitz's murrelet, an ice‐associated seabird of conservation concern, at the northern edge of its range. Over a 2‐year period, we estimated nest density and success at 2 sites, captured and telemetered nesting murrelets, and tested the use of a thermal camera to improve nest detection.

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.

A simple method for algal species discrimination in East China Sea, using multiple satellite imagery

Geoscience Letters, 2022
Satellites can help monitor harmful algal blooms in coastal regions. Methods have been developed using different satellite missions. However, it is necessary to develop a simple and useful method for discriminating harmful algal species that could be ...

Management Participants Perceive That Structural Barriers, Not Information Needs, Most Impede Adaptation in U.S. Fisheries Management

Fish and Fisheries, EarlyView.
ABSTRACT Fisheries are facing increasingly frequent and severe climate change‐related stressors such as marine heatwaves, harmful algal blooms, and species distribution shifts. Many fisheries management bodies have been working to increase the capacity of their regulatory systems to adapt to these new conditions, but progress has been slow and ...

Isolation and Characterization of a Double Stranded DNA Megavirus Infecting the Toxin-Producing Haptophyte Prymnesium parvum

Viruses, 2017
Prymnesium parvum is a toxin-producing haptophyte that causes harmful algal blooms globally, leading to large-scale fish kills that have severe ecological and economic implications.

Competitiveness in American Seafood Requires Climate‐Resilient Fisheries

Fish and Fisheries, EarlyView.
ABSTRACT Recent federal executive actions prioritize restoring American seafood competitiveness through deregulation and production targets, yet these policies overlook the fundamental threat posed by climate‐driven natural hazards. We argue that true seafood competitiveness cannot be achieved through production gains alone because competitiveness also

Evaluating Bias in Self-Reported Symptoms During a Cyanobacterial Algal Bloom

Toxins
Algal blooms produced by cyanobacteria liberate microcystins and other toxins that create a public health hazard. During the 2018 bloom of Microcystis aeruginosa in Florida, USA, residential and recreational exposures were associated with an increased ...

Canine Cyanotoxin Poisonings in the United States (1920s–2012): Review of Suspected and Confirmed Cases from Three Data Sources

Toxins, 2013
Cyanobacteria (also called blue-green algae) are ubiquitous in aquatic environments. Some species produce potent toxins that can sicken or kill people, domestic animals, and wildlife.

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.
