Ice formation, growth, and breakup along the Saint John River (SJR) affects its hydraulic and ecological regimes and leads to the potential for ice jamming that has caused severe flooding and ice runs resulting in loss of life, property damage, and loss of, or damage to, infrastructure. A synopsis of ice regimes and ice jamming along the SJR from Dickey, Maine, USA to Woodstock, New Brunswick, Canada is summarized in this pape...

Summary Porphyromonas species are frequently isolated from the oral cavity and are associated with periodontal disease in both animals and humans. Black, pigmented Porphyromonas spp. isolated from the gingival margins of selected wild and captive Australian marsupials with varying degrees of periodontal disease (brushtail possums, koalas and macropods) were compared phylogenetically to Porphyromonas strains from non‐marsupials...

Summary Carbohydrate‐induced laminitis in horses is characterized by marked changes in the composition of the hindgut microbiota, from a predominantly Gram‐negative population to one dominated by Gram‐positive bacteria. The objective of this study was to monitor changes in the relative abundance of selected hindgut bacteria that have previously been implicated in the pathophysiology of equine laminitis using fluorescence in si...

Summary In the horse, carbohydrate overload is thought to play an integral role in the onset of laminitis by drastically altering the profile of bacterial populations in the hindgut. The objectives of this study were to develop and validate microbial ecology methods to monitor changes in bacterial populations throughout the course of experimentally induced laminitis and to identify the predominant oligofructose‐utilizing organ...
