Abstract

This thesis aims to investigate the effect of environmental drivers on seagrasses by studying shoot-scale and meadow-scale responses, focussing on Zostera marina, Zostera noltii and Halodule wrightii. Seagrasses are plants that have evolved from being terrestrial to living in an entirely marine envi...
