Wind effects on leaf morphology for the mangrove Conocarpus erecta at an oceanic island from the Mexican Pacific Ocean

Leaf morphology was measured and aerodynamical attributes as well as transpiration rates were calculated for the mangrove Conocarpus erecta from sites naturally sheltered or sites exposed to oceanic winds at Socorro Island, Mexico, and compared with those of C. erecta, Laguncularia racemosa, and Rhi...
