Abstract

Deviations from the 1:1 sex ratio are common in dioecious plants. The tropical seagrass Halophila stipulacea is among an extremely rare group of dioecious plants that are widely recognized as female-biased. Here we report on differences in sex ratios between native (Eilat, northern Red Sea) and invasive (Cyprus, Mediterranean Sea) populations. While H. stipulacea populations were female-biased in their native region, invasive populations were either male- or female-biased. The existence of both sexes simultaneously in the Mediterranean invasive populations might help its ongoing expansion in the Mediterranean, thereby threatening local seagrasses species.

Keywords: flowers; Halophila stipulacea; invasive; sex-ratio bias; sexual reproduction

Gidon Winters received his PhD in Molecular Biology and Ecology of Plants from Faculty of Life Sciences, Tel Aviv University, Israel (2009). He was a Post-Doctoral research fellow at the Institute for Evolution and Biodiversity, Westfälische Wilhelms-Universität, Germany (2008–2010), working on effects of thermal stress on Zostera marina. Since his return to Israel, he has been a researcher at the Dead Sea and Arava Science Center (ADSSC). His research interests include seagrass mapping, studying the effects of salinity and climate change on seagrasses, and biotechnology applications of seagrasses. He teaches a seagrass dedicated course at the Inter-University Institute for Marine Science in Eilat.
