    Notes: Seagrass beds in South-east Asia sometimes consist of a mosaic of different species in monospecific patches. We examined whether the magnitude of within-patch variation in the seagrass Halophila ovalis is affected by the presence or absence of surrounding vegetation consisting of another seagrass species Thalassia hemprichii in an intertidal flat in Thailand waters. We measured biomass and growth rates of H. ovalis at the edges and centers of two different types of patches: (i) H. ovalis patches adjoining T. hemprichii vegetation (HT patches), and (ii) H. ovalis patches adjoining unvegetated sand flats (HS patches). Furthermore, we examined the possible effects of interspecific interactions on the growth of H. ovalis by experimentally removing adjoining T. hemprichii at the edges of HT patches. The biomass of H. ovalis was greater at the patch centre than the patch edge in both types of patches. For the growth rate of H. ovalis, significant interactions were detected between patch types and positions in patches. The difference in growth was significant and more than 4-fold between edges and centers of the HS patches, whereas the growth was not significantly different between edges and centers of the HT patches. The removal of T. hemprichii did not significantly affect the growth rate of H. ovalis at the edge of the HT patches. These findings demonstrate that the magnitude of within-patch variation in H. ovalis growth is affected by the conditions of adjoining habitats. However, any effects of local competition with T. hemprichii on H. ovalis growth were not evident in this short-term manipulative experiment.

    Experiment on effects of natural inorganic microparticles and microplastics on mussels of the family Mytilidae from five different bioregions (2021)

    Description: This dataset comprises data obtained during a 6 week-long exposure experiment of mussels of the family Mytilidae to two types of microplastics, namely polymethyl methacrylate (PMMA) and polyvinylchloride (PVC) particles and two types of natural inorganic microparticles, namely diatoms and red clay. This data was obtained from May to September 2019 in five different bioregions, which are Tasmania, Chile, Japan, Cabo Verde and Israel. We recorded body condition index, byssus thread production in 24 hours, clearance rate of the food algae and respiration rate at the end of six weeks of exposure to the four different microparticles (with an exception of the groups exposed to PVC and red clay in Tasmania, which lasted 5 weeks). Mussels were exposed to three concentrations of each particle type, which were 1.5, 15 and 150 mg/l and one group to no particles at all as control.
