Experimental Air Warming of a , Vogel Dominated Tropical Pasture Affects Soil Respiration and Nitrogen Dynamics.

Warming due to global climate change is predicted to reach 2°C in tropical latitudes. There is an alarming paucity of information regarding the effects of air temperature on tropical agroecosystems, including foraging pastures. Here, we investigated the effects of a 2°C increase in air temperature over ambient for 30 days on an established tropical pasture (Ribeirão Preto, São Paulo, Brazil) dominated by the legume Vogel, using a T-FACE (temperature free-air controlled enhancement) system.

Impaired fear inhibitory properties of GABAA and μ opioid receptors of the dorsal periaqueductal grey in alcohol-withdrawn rats.

The dorsal periaqueductal grey (DPAG) is a midbrain region that plays a fundamental role on the expression of the anxiety and fear-related responses. Increased fear and anxiety levels are the most frequent symptoms present in the alcohol withdrawal syndrome. This study aims to assess whether GABA and opioid receptors of the DPAG could be implicated in the expression of the conditioned fear state elicited in alcohol withdrawn-rats.
