Monitoring mercury across the National Wildlife Refuge System using a biosentinel approach

The Journal of Wildlife Management, Volume 90, Issue 4, May 2026.
We measured mercury concentrations in 1,356 dragonfly larvae collected from 30 National Wildlife Refuges across the United States and found wide variability among refuges, spanning the full range reported for other protected lands. Using a management‐focused mercury impairment index, 80% of refuges contained sites classified as moderate or higher risk.

Detecting Harmful Algal Blooms with Isothermal Molecular Strategies

Trends in Biotechnology, 2019
The use of isothermal nucleic acid amplification strategies to detect harmful algal blooms (HABs) is in its infancy. We describe recent advances in these systems and highlight the challenges for the achievement of simple, low-cost, compact, and portable devices for field applications.

A 150-year river water quality record shows reductions in phosphorus loads but not in algal growth potential

Communications Earth & Environment
Eutrophication and proliferation of nuisance and harmful algal blooms are a major cause of water-quality impairment globally. Here, we analyze the world’s longest continuous (150-year) river water-quality dataset for the River Thames, U.K.

Blue Nitrogen: Global Rates and Economic Importance

Earth's Future, Volume 14, Issue 5, May 2026.
Abstract Nitrogen (N) pollution drives widespread coastal ecosystem collapse. In this paper, we argue that mangrove forests represent an undervalued natural mitigation solution for N pollution. By performing a comprehensive global meta‐analysis, we reveal that mangroves remove 870 Gg N annually, which represents an economic value reaching $8.7 billion ...

Bloom-forming cyanobacteria and dinoflagellates in five Argentinian reservoirs: Multi-year sampling

Water Biology and Security
Harmful algal blooms are important threats to reservoir condition. Over a 15-year period, we sampled five Argentinian reservoirs to identify the responsible species for harmful algal blooms and determine the water quality factors driving their occurrence.

Comparative genomics reveals the molecular basis for divergent algicidal strategies in two Alteromonas macleodii strains

Applied and Environmental Microbiology
Marine bacteria such as Alteromonas are key players in regulating algal blooms, yet the genomic basis for their strain-specific algicidal activities remains poorly understood.

Drivers and food web effects of Gonyostomum semen blooms [PDF]

, 2013
The flagellate Gonyostomum semen forms dense late-summer blooms in humic lakes and is a nuisance to swimmers because it forms a slimy coat on the skin, causing irritation in sensitive individuals. Increasing occurrence and bloom incidence of G. semen has

Scientific assessment of marine harmful algal blooms [PDF]

, 2008
Algae are the most abundant photosynthetic organisms in marine ecosystems and are essential components of marine food webs. Harmful algal bloom or “HAB” species are a small subset of algal species that negatively impact humans or the environment.

Eelgrass Habitat Creation in Nantucket Harbor, Massachusetts [PDF]

, 2012
In response to eelgrass habitat losses associated with development and marine activities in and around Nantucket Harbor, a plan to restore a meadow by transplanting eelgrass to previously vegetated areas was developed in conjunction with the Nantucket ...
