Kuo J (2005) A revision of the genus Heterozostera (
Zosteraceae).
Seagrasses (Posidoniaceae,
zosteraceae, Hydrocharitaceae, or Cymodoceaceae) are a key food resource for large, threatened herbivores like manatees (Trichechus manatus) and green turtles (Chelonia mydas)in estuarine and marine areas, although they also consume other submerged aquatic macrophytes (Bjorndal, 1997; Lefebvre et al., 2000).
In Hydrocharitaceae, similar reduction is known from several genera (Cook, 1998a), and the same applies for Juncaginaceae (Haynes et al., 1998a), Najadaceae (Haynes et al., 1998b), Positloniaceae (Kuo & McComb, 1998b), Potamogetonaceae (Haynes et al., 1998c), Zannichelliaceae (Haynes et al., 1998d), and
Zosteraceae (Kuo & McComb, 1998c).
