Melanoma and Other Melanistic Lesions in Brown Bullhead Ameiurus nebulosus From Waterbodies in the Northeastern United States and Canada: Identification of Risk Factors

Journal of Fish Diseases, EarlyView.
ABSTRACT Melanistic lesions, including non‐raised black areas due to proliferations of melanocytes and melanomacrophages in the dermis and epidermis, as well as raised black areas consistent with melanoma, are described in brown bullhead (BBH) Ameiurus nebulosus from three water bodies in the northeastern United States and Quebec, Canada.

Inorganic Carbon Acquisition and Photosynthetic Metabolism in Marine Photoautotrophs: A Summary

Plants
The diffusive availability of CO2 for photosynthesis is orders of magnitude lower in water than in air. This, and the low affinity of ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) for CO2, implies that most marine photoautotrophs ...

Recent occurrence of Cylindrospermopsis raciborskii, in Waikato lakes of New Zealand.

, 2003
Cylindrospermopsis raciborskii is a toxin-producing species of cyanobacteria that in autumn 2003 was recorded for the first time in three shallow (max. depth ≤5 m) Waikato lakes and a hydro-electric dam on the Waikato River, New Zealand.

Key metabolites secreted by Chlorella vulgaris alleviate salt stress in soybean seedlings

Journal of Integrative Plant Biology, EarlyView.
Chlorella vulgaris secretes exosome‐derived linolenic acid and inosine, which alleviate salt stress and enhance salt tolerance in soybean seedlings by activating stress‐responsive signaling networks. ABSTRACT Soil salinization is a major abiotic stress factor that reduces soybean production.

The Potential Use of Marine Microalgae and Cyanobacteria in Cosmetics and Thalassotherapy

Cosmetics, 2017
The use of microalgae and cyanobacteria for nutritional purposes dates back thousands of years; during the last few decades, microalgae culture has improved to become one of the modern biotechnologies. This has allowed high amounts of algal biomass to be

Dinoflagellate responses to nutrients and mangrove leaf organic matter in the bioluminescent Mangrove Lagoon, St. Croix, U.S. Virgin Islands

Journal of Phycology, EarlyView.
Abstract Bioluminescent bays (biobays) are uncommon coastal ecosystems featuring dense populations of dinoflagellates, often found in mangrove‐ringed lagoons with long water retention times and high organic matter (OM) levels. Although mangroves are associated with high dinoflagellate abundance, it remains uncertain how inorganic nutrients compare with

Chemoecological Screening Reveals High Bioactivity in Diverse Culturable Portuguese Marine Cyanobacteria

Marine Drugs, 2013
Marine cyanobacteria, notably those from tropical regions, are a rich source of bioactive secondary metabolites. Tropical marine cyanobacteria often grow to high densities in the environment, allowing direct isolation of many secondary metabolites from ...

The regulatory potential of marine cyanobacteria

, 2007
Life on Earth is driven by the power of oxygenic photosynthesis transforming solar into chemical energy. Cyanobacteria such as Prochlorococcus and Synechococcus belong to the most important primary producers within the oceans and increasingly serve as models for photosynthetic organisms.
