Two new complete mitochondrial genomes (mitogenomes) of the subfamily Chloroperlinae, Haploperla japonica Kohno, 1946 and Sweltsa sp., were sequenced. The two species showed similar gene order, nucleotide composition, codon usage. sp. H. mitogenomes typical circular DNA molecules, with lengths 15,893 bp 16,012 bp, respectively. Standard ATN start TAN stop codons present in most PCGs. All tRNA g...

The relative contribution of aquatic vs. terrestrial organic matter to the diet of consumers in fluvial environments and its effects on bioaccumulation of contaminants such as mercury (Hg) remain poorly understood. We used stable isotopes of carbon and nitrogen in a gradient approach (consumer isotope ratio vs. periphyton isotope ratio) across temperate streams that range in their pH to assess ...
