Triclosan restructures gut communities

Supplementary feeding restructures urban bird communities.

Food availability is a primary driver of avian population regulation. However, few studies have considered the effects of what is essentially a massive supplementary feeding experiment: the practice of wild bird feeding. Bird feeding has been posited as an important factor influencing the structure of bird communities, especially in urban areas, although experimental evidence to support this is...

Differential invariants of [ Restructures

Introduction A differential invariant of a (^-structure is a function which depends on the r-jet of the (^-structure and such that it is invariant under the natural action of the pseudogroup of diffeomorphisms of the base manifold. The importance of these objects is clear, since they seem to be the natural obstructions for the equivalence of (2-structures. Hopefully, if all the differential inv...

Sensory Experience Restructures Thalamocortical Axons during Adulthood

The brain's capacity to rewire is thought to diminish with age. It is widely believed that development stabilizes the synapses from thalamus to cortex and that adult experience alters only synaptic connections between cortical neurons. Here we show that thalamocortical (TC) inputs themselves undergo massive plasticity in adults. We combined whole-cell recording from individual thalamocortical n...

Perturbation and restoration of the fathead minnow gut microbiome after low-level triclosan exposure

BACKGROUND Triclosan is a widely used antimicrobial compound and emerging environmental contaminant. Although the role of the gut microbiome in health and disease is increasingly well established, the interaction between environmental contaminants and host microbiome is largely unexplored, with unknown consequences for host health. This study examined the effects of low, environmentally relevan...
