Seagrass coastal protection services reduced by invasive species expansion and megaherbivore grazing

Seagrasses provide an important ecosystem service by creating a stable erosion-resistant seabed that contributes to effective coastal protection. Variable morphologies and life-history strategies, however, are likely to impact the sediment stabilization capacity of different seagrass species. We question how opportunistic invasive species and...

One aspect of the dynamics of a coast, partly protected by a row of groynes

A mathematical theory about phenomena that occur if on a coastal area groynes are constructed. The theory is a simplification: it just deals with one aspect. The starting point in the coastal equation of Pelnard-Considère and a linearisation between the transport along the groyne and the size of the 'step' in the coastline at the groyne. The...
