Range extension of Halophila stipulacea (Hydrocharitaceae) in the Mediterranean
TL;DR: The species has expanded its Mediterranean area considerably, as is apparent from recent records from Malta and Cyprus, and it is obvious that H. stipulacea is now well established in the Aegean waters.

Abstract: Halophila stipulacea (Forsk.) Aschers. is a sea-grass which is widely distributed along the coasts of the western Indian Ocean and the Red Sea. In 1895 Fritsch (Verh. Zool. Bot. Ges. Wien 45, 1895, p. 104) recorded the species from the Island of Rhodos in the Aegean Sea. This was the first record of the species from the Mediterranean. There can be no doubt that it penetrated the Mediterranean via the Suez Canal, which was completed in 1869. Although there are no early records of its occurrence in the Suez Canal, it is significant that it was the only sea-grass found during the exploration of the canal by Munro Fox in the autumn of 1924; at that time it was abundant in several localities in the canal. Forti’s record (Nuov. Giorn. Bot. Ital. 34, 1927, p. 714—716) of the species is the second for the Mediterranean; he reported it as being not uncommon in the Dodecanesos. I myself have seen specimens that were collected on Samos in 1924 and near Cape Matapan in 1955 (Den Hartog, Sea-grasses of the world, 1970, p. 260). In spite of the fact that the number of published records is still scanty, it is obvious that H. stipulacea is now well established in the Aegean waters. Further the species has expanded its Mediterranean area considerably, as is apparent from recent records from Malta (Lanfranco, The Maltese Naturalist I, 1970, 16—17, stencilled) and Cyprus.

Halophila stipulacea, a review of a successful immigration
TL;DR: The recorded expansion in the Eastern Mediterranean of Halophila stipulacea, which appeared in this sea after the Suez Canal had been opened, is reviewed in this paper, where the present geographical and ecological distributions of this plant in the Mediterranean are summarized and its phenology in this basin is discussed.

TL;DR: In this paper, the authors systematically reviewed 164 studies related to H. stipulacea in its native and invasive ranges and identified knowledge gaps and developed a critical strategy to understand its invasive capacity and implement an effective monitoring and conservation plan to mitigate its potential spread outside its native ranges.
Flowering under controlled conditions by Cymodocea serrulata, halophila stipulacea, syringodium isoetifolium, zostera capensis and Thalassia hemprichii from Kenya
TL;DR: It is concluded that a wide range of environmental conditions is involved in the reproductive physiology of members of this tropical seagrass flora.

Uptake of Cadmium and the Effect on Viability of Leaf Cells in the Seagrass Halophila stipulacea (Forsk.) Aschers.
TL;DR: The uptake of cadmium (Cd) in the leaves and lower parts of Halophila stipulacea (Forsk.) Aschers was studied in laboratory experiments and the toxicity of cadium was assessed by the leaf-cell viability test.
