Annotation on Mangrove Plants 总被引：1，自引：0，他引：1
This paper reviews and discusses the technical terms and definition of mangrove and lnangal, as well as mangrove plant. The word mangrove has been used to refer either to the constituent plant of tropical and subtropical intertidal community or to the community itself but this usage makes mote confusion. Being leaved mangrove in the more limited sense for the constituent plant species, mangal was proposed by MacNae (1968) as a term for mangrove community, which has been universally applied to most previous studies and should be adopted now. Mangrove should be therefore defined as a tropical and subtropical tree restricted to intertidal zones, which possesses some morphological specializion and physiological mechanism adapted to its habitat, and mangal as a tropical and subtropical forest community restricted to marine intertidal zones and periodically inundeated by the tides, A new term “consortive plant” is proposed here for herb. liana, epiphyte or parasite, which is restricted in the strict mangrove habitat. 相似文献

The Ecology of a Novel Symbiosis Between a Marine Peritrich Ciliate and Chemoautotrophic Bacteria 总被引：1，自引：0，他引：1
Abstract. A symbiosis between a sessile colonial ciliate, Zoothamnium niveum HEMPRICH & EHRENBERG. 1831. and chemolithoautotrophic bacteria oxidizing reduced sulfur compounds is described. The ciliates and their ectosymbionts occur on mangrove peat in the Caribbean. The feather-shaped ciliate colonies expand and contract, thus exposing the microbes alternately to oxygenated water above and sulfidic water within the boundary layer developed on the surface of the highly sulfidic peat. The symbioticciliates colonize sites with high sulfide flux where the microbial surface mat has been disturbed and grow there until the microbe mat re-establishes itself. 相似文献
