Virtual reality rehabilitation systems often represent actions through virtual limbs. However, previous observation-only studies suggest that frontoparietal networks involved in action observation and execution may also be engaged by simpler virtual effectors. In the present fMRI study, we examined whether the visual presence of a virtual limb modulates brain activity during both action execution and action observation in a vi...

The ongoing need to sustainably manage fishery resources can benefit from fishery-independent monitoring of fish stocks. Camera systems, particularly baited remote underwater video system (BRUVS), are a widely used and repeatable method for monitoring relative abundance, required for building stock assessment models. The potential for BRUVS-based monitoring is restricted, however, by the substantial costs of manual data extrac...

Aim Seasonally dry tropical forest ( SDTF ) of the Caribbean Islands (primarily West Indies) is floristically distinct from Neotropical SDTF in Central and South America. We evaluate whether tree species composition was associated with climatic gradients or geographical distance. Turnover (dissimilarity) in species composition of different islands or among more distant sites would suggest communities structured by speciation a...
