“…It is clear that certain exchanges are likely to co-occur (e.g. high hydro dynamic energy and turbidity) (de los Santos et al 2010). Wolanski (2007) showed that phy sical and chemical parameters are often linked to biological aspects of ecosystems.…”

“…Combining 2 factors may cause different types of interactions: synergistic, antagonistic and independent (de los Santos et al 2010, La Nafie et al 2012. A clear example of one exchange fully overruling a second exchange was shown by de los Santos et al (2010), who demonstrated that light availability (related to turbidity) was much more important for seagrass health than changes in hydrodynamic energy.…”

“…Seagrass meadows are facing severe declines worldwide, due to the increase of human activities (Orth et al ; Halpern et al ; Waycott et al ), threatening their resilience and survival. Being sessile organisms, seagrasses can to some extent adapt their morphological and physiological traits to their local conditions, influencing their resilience to (natural or human‐induced) stressors (Short and Wyllie‐Echeverria ; Touchette and Burkholder ; Peralta et al ; Lee et al ; Cabaço et al ; de los Santos et al ).…”

“…However, for seagrass species, there are still only a very limited number of studies available on mechanical traits/strength of leaves and reproductive shoots (Patterson et al ). Available studies have focused on comparing species‐specific traits (de los Santos et al ) and on quantifying the effect of specific abiotic conditions such as the effect of nutrient enrichment (La Nafie et al ), wave exposure (de los Santos et al ; La Nafie et al ), and the spatial and temporal variability in abiotic conditions (de los Santos et al ). In their study, La Nafie et al () demonstrated that nutrient enrichment significantly reduced leaves strength and stiffness in Halophila ovalis .…”

Seagrasses are marine flowering plants distributed worldwide. They are however threatened, mostly due to the increase of human activities. Seagrasses have the capacity to adapt their morphological, physiological, and mechanical traits to their local conditions. Mechanical traits have been identified as a good tool to investigate a plant-species capacity to withstand physical forces or disturbances but are still sparsely studied in seagrasses. With this study, we aimed to assess how the mechanical traits of a broadly spread seagrass species vary along a latitudinal gradient in relation to its morphometric plasticity and nutrient status. We found that seagrasses acclimate their mechanical traits in relation to their physiological or morphological traits, both over the growing season and across a latitudinal range: leaves were weaker and thinner in northern areas, particularly at the end of the growing season. Besides the influence of the latitudinal gradient, leaf mechanical strength and stiffness were both strongly affected by their morphometric plasticity. Moreover, we showed that leaves mechanical traits change depending on their nutrient status: leaves were stronger and stiffer in oligotrophic conditions as compared to more eutrophic conditions. Thus, our results imply that, under eutrophication, leaves become weaker and thus more vulnerable to physical forces. This vulnerability is higher in the north at the end of the growing season. The latter is consistent with the more ephemeral character of northern seagrass meadows, in contrast to the more evergreen southern meadows.

Ongoing climate changes alter a broad range environmental variables in coastal ecosystems, which may lead to changes in species range distributions or collapse of populations. It is often assumed that changes in environmental parameters affect organisms in a nonadditive way and multifactorial experiments are therefore needed to obtain a better prediction of the effects of climate change. We studied experimentally how combinations of high temperature, low light and high nitrogen (HN) availability affect eelgrass (Zostera marina), which is an important foundation species on the northern hemisphere. Plants were cultured under optimal (15°C) and high (25°C) temperature, limiting and saturating light, and low and high ammonium availability in a 3‐factorial design. We found that individual exposure to heat and shade, respectively, had a negative effect on eelgrass while the effect of exposure to HN‐availability alone was less harmful. Exposure to combinations of two or three stressors simultaneously had a stronger (negative) effect on eelgrass than exposure to each stressor individually, but the combined effects of exposure to multiple stressors were largely similar to the expected additive responses. A synergetic effect was only found in case of mortality when eelgrass plants were exposed to all three stressors simultaneously. The effects of exposure to single or multiple stressors could largely be explained from alterations in the C‐budget of the plants: exposure to one or more stressors lowered the acquisition of C, drained the C‐reserves and sometimes allocated energy to defense or repair processes instead of growth resulting in reduced growth and higher mortality.
