We tested the prey-base hypothesis to determine whether selection of red squirrel (Tamiasciurus hudsonicus) midden sites (cone caches) by American martens (Martes americana) for resting and denning could be attributed to greater abundance of small-mammal prey. Five years of livetrapping at 180 sampling stations in 2 drainages showed that small mammals, particularly red-backed voles (Clethrionom...

The present study dealt with the identification of a bacterium having dominance in earthworm (Lennogaster pusillus) midden by 16S rDNA based genomic analysis. The bacterium identified was Aeromonas punctata strain JM10 (Genbank Accession No: GU205197.1). Isolated DNA of the bacterium showed amplicon band of 1500 bp, when resolved on agarose gel. Amplification of the 16S rDNA gene from the Aerom...

Populations of sturgeon (Acipenseridae) have experienced global declines, and in some cases extirpation, during the past century. In the current era of climate change and over-harvesting of fishery resources, climate models, based on uncertain boundary conditions, are being used to predict future effects on the Earth's biota. A collection of approximately 400-year-old Atlantic sturgeon spines f...
