In this contribution we studied the trophic ecology of four Characidae species from the Cavalo Stream, upper Tocantins River, considering diet overlap and stingray hood scoop trophic niche breadth.The diet of the four species was composed of adult and immature insects, both autochthonous and allochthonous in origin.Autochthonous items dominated the
With the depletion of natural resources and the deterioration of environment, natural fiber based biomaterials are attracting more and more attentions.Natural fibers are considered to be renewable, biodegradable, and ecofriendly, and have been applied to be used as alternative reinforcements to traditional glass fibers for polymer based composites
ABSTRACT An increasing number of microbes are being identified that organize catabolic pathways within self-assembling proteinaceous structures known as bacterial microcompartments (BMCs).Most BMCs are characterized by their singular substrate specificity and commonly employ B12-dependent radical mechanisms.In contrast, a less-well-known BMC type u
