Hypoperfusion in response to epinephrine in local anaesthetics : Investigation of dependence on epinephrine concentration, spread of hypoperfusion and time to maximal cutaneous vasoconstriction

Objectives: The present study aimed to examine hypoperfusion in response to epinephrine following the administration of a local anaesthetic. The . concentration of epinephrine that causes maximal hypoperfusion, the . spread of hypoperfusion in the tissue and the . time to the stabilization of hypoperfusion were investigated. Methods: Blood perfusion was monitored using laser Doppler velocimetry an

Optimal response to habitat linkage of local fish diversity and mean trophic level

Spatially segregated ecosystems are frequently subsidized by cross-habitat linkages, but the extent to which the functional links between habitats influence local community attributes, such as consumer and food web structure is still poorly understood. Using the bidirectional linkage between benthic and pelagic habitats in floodplain lakes, we address this important question by looking for evidenc
