Abstract. The flow around the reproductive organs of the seagrass Zostera marina L. (Potamogetonales) was, therefore, examined in a … Bull. However, Reusch (2003) found that seed production and pollination potential of Z. marina was negatively affected by fragmentation and manipulation of shoot densities in the parent population. Zostera marina. [3][7] For example, it provides a sheltered spawning ground for the Pacific herring (Clupea pallasii). [5] The fruit is a nutlet with a transparent coat containing the seed. Submarine pollination in the marine angiosperm Zostera marina (Zosteraceae). Invasive species have been shown to have a negative effect on eelgrass and associated ecosystems. [17] It has also been dried and used as stuffing for mattresses and furniture.[17]. [8] Remaining geese ate less-preferred food plants and algae, and hunters subsequently noticed that brant meat began to taste different. I. ; Liu, Y.S. The inflorescence is about 10 cm long. POLLEN TRANSPORT IN FLOW FIELDS AND CAPTURE BY STIGMAS1 JOSEF DANIEL ACKERMAN2 Sections of Plant Biology, and Ecology and Systematics, Cornell University, Ithaca, New … Current flow around Zostera marina plants and flowers: implications for submarine pollination. Ackerman, J. D. 1997. Literature Cited. Zostera marina is a flowering vascular plant species as one of many kinds of seagrass, with this species known primarily by the English name of eelgrass with seawrack much less used, and refers to the plant after breaking loose from the submerged wetland soil, and driftin free with ocean current and waves to a coast … In some areas, such as the coastal waters off Virginia, meadows of Zostera marina, or eelgrass, were so abundant that, as recently as 100 years … The intention of this study was to extend such analyses to seagrasses, a group of ecologically important flowering plants exhibiting marine subaqueous pollination. Submarine pollination in the marine angiosperm Zostera marina (Zosteraceae) II. [3] The seagrass is a favorite food of several species of waterfowl, which may also distribute the seeds. II. Ask your question. They are commonly found in estuaries or shallow areas with a muddy or sandy substrate and can grow completely submerged. water is a regular mode of transport for the male gametes among the lower plant groups such as algae, bryophytes, and pteridophytes. Flow chamber observations of the filamentous pollen of Zostera marina L. (Potamogetonales) revealed that pollen rotated and moved toward inflorescences where they were captured by stigmas. Example: Zostera marina… The dispersion and capture of differently shaped particles within a Zostera marina L. (eelgrass; Zosteraceae) bed were examined to understand submarine pollination and other dispersals. Ask your question. 165:504.
