Glyphosate-based herbicides (GBHs) are extensively used worldwide, raising concerns about their potential effect on non-target aquatic ecosystems. This study investigated the short-term physiological effects of a commercially available GBH on the seagrass Zostera marina under controlled mesocosm conditions. Z. marina individuals were exposed to three concentrations of glyphosate (0.165, 51, and 5100 mg L−1 ) fo...
Marine heatwaves (MHWs) are increasing in frequency and intensity as part of climate change, yet their impact on seagrass is poorly known. The present work evaluated the physiological and morphological responses of Cymodocea nodosa to a MHW. C. nodosa shoots were transplanted into a mesocosm facility. To simulate a MHW, water temperature was raised from 20 to 28 degrees C, kept 7 days at 28 degrees C, cooled do...
Seagrasses play a high ecological role and provide a large range of ecosystem services, yet they are globally threatened by climate change. The seagrasses Zostera marina and Cymodocea nodosa share the same ecological niche in Ria Formosa, Southern Portugal, where their thermal distribution limits meet. While C. nodosa has its northern distribution limit in Portugal, Z. marina reaches its southern distribution l...
