    Climate change and the presence of invasive species will threaten the persistence of the Mediterranean seagrass community

    Pedro Beca-Carretero, Gidon Winters, Mirta Teichberg, Gabriele Procaccini, Fabian Schneekloth, Ramon H Zambrano, Kelcie L Chiquillo, Hauke Reuter
    Abstract

    The Mediterranean Sea has been experiencing rapid increases in temperature and salinity triggering its tropicalization. Additionally, its connection with the Red Sea has been favouring the establishment of non-native species. In this study, we investigated the effects of predicted climate change and the introduction of invasive seagrass species (Halophila stipulacea)

    The effect of anaerobic remineralization of the seagrass Halophila stipulacea on porewater biogeochemistry in the Gulf of Aqaba

    Neta Soto, Gidon Winters, Gilad Antler
    Abstract

    Seagrasses form oxidizing microenvironments around their roots, creating complex and strong redox gradients, thus affecting the rates of microbial carbon mineralization in their surrounding sediments. Since seagrasses are continuously being lost worldwide, a deeper understanding of the changes that occur within different seagrass sediments following the disappearance

    Undisturbed Posidonia oceanica meadows maintain the epiphytic bacterial community in different environments

    Alice Rotini, Chiara Conte, Gidon Winters, Marlen I Vasquez, Luciana Migliore
    Abstract

    Seagrasses harbour different and rich epiphytic bacterial communities. These microbes may establish intimate and symbiotic relationships with the seagrass plants and change according to host species, environmental conditions, and/or ecophysiological status of their seagrass host. Although Posidonia oceanica is one of the most studied seagrasses in the world, and bacteria

    Effects of anthropogenic pressures on the seagrass Halophila stipulacea and its associated macrozoobenthic communities in the northern Gulf of Aqaba

    Hung Manh Nguyen, Cristina Andolina, Salvatrice Vizzini, Maria Cristina Gambi, Gidon Winters
    Abstract

    Halophila stipulacea is a tropical seagrass species, native to the Red Sea, Persian Gulf, and Indian Ocean, while invasive to the Mediterranean and Caribbean Seas. The benthic fauna assemblages associated with H. stipulacea in its native habitats and the potential effects of anthropogenic stressors on these assemblages remain unknown. We compared meadow characteristics, associated fauna assemblages and trophic niche structures of

    Responses of two Acacia species to drought suggest different water-use strategies, reflecting their topographic distribution

    Daphna Uni, Efrat Sheffer, Tamir Klein, Rachamim Shem-Tov, Nitzan Segev, Gidon Winters
    Abstract

    Soil water availability is a key factor in the growth of trees. In arid deserts, tree growth is limited by very dry atmosphere and soil conditions. Acacia tree species are distributed in the most arid deserts of the globe, therefore they are well adapted to heat and long droughts. Understanding why some plants do better than others in some environments is a key question

    Do urban tree hydraulics limit their transpirational cooling? A comparison between temperate and hot arid climates

    Limor Shashua-Bar, Mohammad A Rahman, Astrid Moser-Reischl, Aviva Peeters, Eleonora Franceschi, Hans Pretzsch, Thomas Rötzer, Stephan Pauleit, Gidon Winters, Elli Groner, Shabtai Cohen
    Abstract

    Evaporative cooling due to transpiration of urban trees in two contrasting climates is the subject of this study. Transpiration was studied experimentally on local tree species at ‘tree lab’ sites in Munich, Germany (temperate climate) and in Beer Sheva, Israel (hot arid climate), within various settings (park, street, square) with natural and sealed surface conditions

    Superior growth traits of invaded (Caribbean) versus native (Red sea) populations of the seagrass Halophila stipulacea

    Abstract

    The seagrass Halophila stipulacea is native to the Red Sea. It invaded the Mediterranean over the past century and most of the Caribbean over the last two decades. Understanding the main drivers behind the successful invasiveness of H. stipulacea has become crucial. We performed a comprehensive study including field measurements, a mesocosm experiment, and a literature

    Peak photosynthesis at summer midday in Acacia trees growing in a hyper-arid habitat

    Daphna Uni, Efrat Sheffer, Gidon Winters, AC Lima, H Fox, Tamir Klein
    Abstract

    Key message

    Desert Acacia trees photosynthesize during the hot dry summer, and use stored carbon for summer growth.

    Trees that grow in hyper-arid environments can provide important insight into the role of carbon use and carbon storage for tree survival and growth in extreme conditions. Acacia trees, in particular, experience some of the most arid conditions in which

    Gene co-expression network analysis for the selection of candidate early warning indicators of heat and nutrient stress in Posidonia oceanica

    Alex R Santillán-Sarmiento, Jessica Pazzaglia, Miriam Ruocco, Emanuela Dattolo, Luca Ambrosino, Gidon Winters, Lázaro Marin-Guirao, Gabriele Procaccini
    Abstract

    The continuous worldwide seagrasses decline calls for immediate actions in order to preserve this precious marine ecosystem. The main stressors that have been linked with decline in seagrasses are 1) the increasing ocean temperature due to climate change and 2) the continuous inputs of nutrients (eutrophication) associated with coastal human activities. To avoid the

    An invasive seagrass drives its own success in two invaded seas by both negatively affecting native seagrasses and benefiting from those costs

    Kelcie L Chiquillo, Paul H Barber, Marlen I Vasquez, Edwin Cruz-Rivera, Demian Alexander Willette, Gidon Winters, Peggy Fong
    Abstract

    The nature and strength of interactions between native and invasive species can determine invasion success. Species interactions can drive, prevent or facilitate invasion, making understanding the nature and outcome of these interactions critical. We conducted mesocosm experiments to test the outcome of interactions between Halophila stipulacea, a seagrass that invaded
