The data are population sizes of yeast Saccharaomyces cerevisiae growth in laboratory cultures over a period of several days with different levels of growth inhibitor cycloheximide and of nutrient levels.

The prevalence of antibiotic resistance genes in microbial communities from sewage wastewater streams and from offshore marine sediments in the vicinity of sewage wastewater outfalls in Southeast Florida was investigated from June 2018 to March 2019. Sediment and wastewater samples were analyzed for 15 different antibiotic resistant gene targets via polymerase chain reaction (PCR) presence/absence assays in Southeast Florida coral reef environments. Data collected from five sites (Broward North Wastewater Treatment Plant (WWTP), Broward North WWTP Outfall, Haµlover (Miami-Dade North) Outfall, Hollywood Outfall, Hollywood WWTP, and Miami-Dade North WWTP) illustrated widespread prevalence of antibiotic resistance genes in these microbial communities with the highest concentrations occurring in the sewage wastewater stream and in close proximity to the outfall pipe and outfall. Data indicated seasonal (wet versus dry season) trends and potential public and ecosystem health risks. Additionally, a reef in the Florida Keys was evaluated during the wet season using the same tools and approach prior to and after diseased corals were treated with amoxicillin. Resistance to amoxicillin was only observed in the post-treatment sample set.

The frequency of cyanobacterial blooms appears to have increased globally in recent decades due to human induced eutrophication and climate change. Cyanobacterial blooms can produce several groups of toxins, among which microcystin-LR (MC-LR) is one of the most abundant. Effects of MC-LR on avian microbiome have not been studied and studies in laboratory murines are limited to metabarcoding of prokaryotes. Using RNA shotgun sequencing we compared the richness and composition of metabolically active prokaryotes, expressed virulence factors, antimicrobial resistance genes, metabolic pathways, gene ontology terms, enzymes, and proteins in mallards that were orally exposed to a sublethal dose of MC-LR for one week and unexposed birds.

The data are population sizes of yeast Saccharaomyces cerevisiae growth in laboratory cultures over a period of several days with different levels of growth inhibitor cycloheximide. Our results provide rigorous experimental tests of new and old theory, demonstrating how the traditional notion of carrying capacity is ambiguous for populations diffusing in spatially heterogeneous environments.
