Popis: This study examined the response of tropical seagrass species Thalassia testudinum to a combination of heat and hypoosmotic stress. These two stressors are of major importance, as studies predict a rise in sea surface temperatures, as well as in increase in precipitation in the Caribbean region. Field-studies revealed the plant to exhibit a slow stress response to e.g. elevated temperatures and changes in salinity, however, they also showed the severity in changes in these factors. While in-situ observations allow for a good setting of treatment levels, there is a scarcity of in-culture experiments exposing T. testudinum to heat and osmotic stress, especially in combination. These experiments are essential to precisely delineate the effects and establish causality, thereby eliminating potential confounding factors. This in-culture experiment was performed in the culturing facilities of the GEOMAR building (54°19'48N 10°08'54E) using a culture of four T. testudinum clones. Plants were originally collected in 2017 from waters in front of the Smithsonian Tropical Research Institute in Bocas del Toro, Panama (9°21'04N 82°15'26W). Subsequently, they were cultivated in the GEOMAR culturing facilities under water temperatures of 28°C and salinities levels between 31-34. For the experiment, plants were replanted in February 2023 to fit a fully factorial experiment comprising all four clones crossed over four treatments: control (T=28°C; S=32.5), heat stress (T=34°C; S=32.5), hypoosmotic stress (T=28°C; S=27) and combined heat and hypoosmotic stress (T=34°C; S=27). Each treatment held three replicates (100 L aquaria), which in turn held two boxes of each clone with a starting number of two shoots each. Plants were given sufficient time to establish until overall net new growth in form of new shoot production was observed. After this initial establishment, a one week warming phase for heat treatments preceded the four-week stress period throughout August 2023, followed by cool-down phase and subsequently a total of six ...
