Spatio-temporal variability of ichthyophagous bird assemblage around western Mediterranean open-sea cage fish farms.

Ichthyophagous birds aggregate at cage fish farms attracted by caged and associated wild fish. Spatio-temporal variability of such birds was studied for a year through seasonal visual counts at eight farms in the western Mediterranean. Correlation with farm and location descriptors was assessed.

A meta-analysis approach to the effects of fish farming on soft bottom polychaeta assemblages in temperate regions.

Marine fish farms could cause environmental disturbances on the sediment due to uneaten food and fish faeces that impact the marine benthos. Polychaete assemblages are considered good indicators of environmental perturbations. The present study aimed to establish groups of polychaetes as potential indicators of fish farm pollution.

Myasthenia gravis: the otolaryngologist's perspective.

Myasthenia gravis is a motor neuron disease caused by the presence of antibodies against acetylcholine receptors that interfere with the proper function of the neuromuscular junction. Twenty percent of patients with myasthenia gravis present some type of bulbar deficits such as rhinolalia, dysphagia or dysphonia as the first symptom of disease. We report 5 patients with deficits that illustrate different aspects of the disease.
