Characterization and phylogenetic analysis of the complete mitochondrial genome of Terapon theraps (Perciformes: Terapontidae) [PDF]
We assembled the complete mitochondrial genome of Terapon theraps based on high-throughput Illumina sequencing. The mitochondrial genome of T. theraps is 16,587 bp in length, containing 13 protein-coding genes (PCGs), 22 tRNAs, two rRNAs, and one ...

Mitochondrial DNA patterns describe the evolutionary history of the bonnethead shark Sphyrna tiburo (Linneus 1758) complex in the western Atlantic Ocean. [PDF]
Abstract The apparent lack of physical barriers in the marine realm has created the conception that many groups have a constant gene flow. However, changes in ocean circulation patterns, glacial cycles, temperature, and salinity gradients are responsible for vicariant events in many fish species, including sharks.

Potential metabolic records in isotope signals of chondrichthyan hard tissues. [PDF]
Abstract Recent advances have demonstrated that the field metabolic rates (FMRs) of teleost fishes can be quantified from stable isotope compositions of carbonate‐biomineralized otoliths. Bones and teeth, in addition to bioapatite, contain carbonate and should retain a similar isotopic expression of metabolic rate.

The Chemistry and Biology of the Tetrodotoxin Natural Product Family. [PDF]
Tetrodotoxin is best known as the poison of the pufferfish, which is a delicacy in Japanese cuisine. Its toxicity arises from the selective blockage of NaV channels, which is depicted for the NaV1.7 pore, highlighting the DEKA motif, which permeates sodium ions.

Environmental heterogeneity influences liana community differentiation across a Neotropical rainforest landscape. [PDF]
By analyzing liana community variation among land units (LUs) that differ in geomorphology and soil properties along a 640‐ha tropical rainforest landscape in a neotropical reserve, we found strong evidence supporting our hypothesis that environmental heterogeneity, as represented by discrete LUs, promotes differentiation in liana composition across ...
