Synergistic and Antagonistic Effects of Chemical Pollutants and Parasitic Fungi on Cyanobacterial Metabolism

Environmental Toxicology, EarlyView.
ABSTRACT Freshwater ecosystems are increasingly impacted by anthropogenic pollutants, including the widely used herbicide metolachlor (MET) and cigarette butt (CB) litter. Parasites represent an additional biotic stressor that can modulate pollutant effects on their hosts.

Extraction and Quantification of Alkanes in Cyanobacteria

Bio-Protocol, 2015
Many species of cyanobacteria accumulate alkanes in their cells. It has been reported that these cyanobacteria accumulate mainly 15 long carbon chain alkane, pentadecane (C15H32), or/and 17 long chain alkane, heptadecane (C17H36).

Survey of extrachromosomal DNA found in the filamentous cyanobacteria [PDF]

Journal of Bacteriology, 1978
Cleared lysates of 13 species of filamentous cyanobacteria were examined for the presence of extrachromosomal DNA by using agarose gel electrophoresis and ethidium bromide staining. Seven of the 13 species contained extrachromosomal covalently closed circular DNA, and all but 1 species contained multiple elements.

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.

Response of Fecal Bacteria and Fungi to Tannin‐Rich Diets in Sika Deer (Cervus nippon): Evidence from Both Feeding Experiments and Field Investigations

Integrative Zoology, EarlyView.
Feeding with tannin‐rich diets altered the fecal microbial composition and increased the relative abundance of tannin‐degrading microbes. We hypothesize that fecal bacteria and fungi may play important roles in helping herbivores adapt to tannin‐rich diets but respond to different tannin concentrations varies.

Developmental Biology in Cyanobacteria

Life, 2019
Filamentous, heterocyst-forming cyanobacteria are phototrophic multicellular organisms in which N2-fixing heterocysts and CO2-fixing vegetative cells exchange regulators and nutrients [...]

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.

Fitoplancton de una laguna pampásica (San Miguel del Monte, Buenos Aires, Argentina)

Biología Acuática, 2019
Phytoplankton assemblages were analyzed taking into account the functional groups in a shallow lake connected to the lower basin of Salado River. Samples were obtained monthly (9/1997-8/1998), from the affluent (E1), San Miguel del Monte lake (E2) and ...

Description of Flavicapitulum gen. nov. and two new species of Marmoreocelis from thermal habitats in the Americas

Journal of Phycology, EarlyView.
Abstract Three novel taxa in the Coleofasciculales were observed in hot springs in Yellowstone National Park, Wyoming, United States, and in the Tabaconcito thermal springs on the Rio Tabacón in Costa Rica. Flavicapitulum vaporiphilum gen. et sp. nov. was located in a supported clade with Gracilinea and Marmoreocelis.
