One preserved mussel specimen including both the left and right valves. The specimen exhibits a triangular shape; thick shell; white internal coloring; brown external coloring; no external sculpturing. Collected in the Trinity basin. The specimen measures between 60 - 100 mm in length and was assessed to be relatively-recently dead when collected.

One preserved mussel specimen including both the left and right valves. The specimen exhibits an elliptical shape; white internal coloring; tan external coloring; no external sculpturing. The specimen measures between 0 - 60 mm in length and was assessed to be very-recently dead when collected.

One preserved mussel specimen including both the left and right valves. The specimen exhibits an oval shape; white internal coloring; tan external coloring; no external sculpturing. The specimen measures between 60 - 100 mm in length and was assessed to be very-recently dead when collected.

This review explores the latest developments in Fourier transform mass spectrometry and Orbitrap based metabolomics technology, its advantages and drawbacks for using in metabolomics and lipidomics studies, and development of novel approaches for processing high resolution mass spectrometry data.

This essay poses an argument for epigenetics having a potentially profound role in our understanding of inheritance, natural selection and evolution, and deserving more attention.

Article on the detection and quantification of engineered proanthocyanidins in transgenic plants.

Article describes how, in many raptor species, hatching asynchrony results in a size hierarchy among nestlings, which may facilitate brood reduction by means of sibling aggression-induced mortality, especially in times of low food resources. The authors studied the influence of hatch rank, brood size, and brood age on aggression and feeding rates among Red-shouldered Hawk (Buteo lineatus) nestlings in suburban southwestern Ohio.
