Phenological Trends with Latitude in the Mangrove Tree Avicennia Marina
The Journal of Ecology, 1990(1) Leaf fall and reproductive phenology of Avicennia marina assessed during 1982-83 using litter fall collections from twenty-five sites in Australia, Papua New Guinea and New Zealand revealed major trends with latitude. Flowering shifted from November- December in northern tropical sites, to May-June in southern temperate sites.

Decomposition of Avicennia marina on an iron-smelting slag substrate
Austral Ecology, 2001AbstractThe present study, conducted near Newcastle, Australia, used a blocked analysis of variance experimental design to compare initial nutrient concentrations and decomposition rates of Avicennia marina (grey mangrove) grown on sand and rock blast furnace slag.

The Nature of Growth Rings in the Mangrove, Avicennia marina
2023In this study we look at the irregular growth pattern of Avicennia marina mangroves on Guam to identify the number of growth layers the tree produces each year. Using a cambial marking technique and stable carbon isotopes, we looked at the growth patterns of Avicennia marina to identify the periodicity of growth layers and determine whether this ...

New Abietane Diterpenoids from the Mangrove Avicennia marina
Planta Medica, 2008Phytochemical investigations of the twigs of Avicennia marina yielded three new abietane diterpenoids 11-hydroxy-8,11,13-abietatriene 12- O-beta-xylopyranoside ( 1), and a pair of inseparable epimers 6 Halpha-11,12,16-trihydroxy-6,7-secoabieta-8,11,13-triene-6,7-dial 11,6-hemiacetal ( 2) and 6 Hbeta-11,12,16-trihydroxy-6,7-secoabieta-8,11,13-triene-6,7-

Knee Roots in Avicennia marina (Forsk.) Vierh.
Annals of Botany, 1971The occurrence of knee roots in Avicennia marina (Forsk.) Vierh. is reported and specimens at various stages of development are described Knee roots arise from horizontal roots in a manner similar to pneumatophores but anatomically they resemble horizontal roots After re-entering the soil the knee root reverts to a horizontal position and gives rise to

Periodicity in phloem rings of Avicennia marina?
2005On sanded stem disks of the mangrove species Avicennia marina (Avicenniaceae) a clear alternation of light colored bands of phloem and darker xylem bands, which are created by successive cambia, can be observed. However, little is known about the factors responsible for the formation of a new cambium and whether these are formed at periodic intervals ...

Organochlorine pesticides in Avicennia marina from the Mumbai mangroves, India
Chemosphere, 2009This paper examines the concentration levels of organochlorine pesticides (OCPs) such as hexachlorocyclohexane (HCH) (alpha, beta and gamma), Aldrin, Endosulfan (alpha, beta), DDE, DDD, and DDT in the leaf, root and sediment part of Avicennia marina, a dominantly distributed mangrove species in Mumbai.

Phytochemical studies on mangrove Avicennia marina
2013Stigmasterol-3-O-β-D glucopyranoside (1) has been isolated from pnematophores (aerial roots) of Avicennia marina (Forssk.) Vierh. along with two triterpenoids, ursolic acid (2) and α-amyrin (3). Compounds 1 and 2 are reported for the first time from this plant. Compound (1) was found to possess moderate anti-glycation activity.

Ecosystem Services of Avicennia marina in the Red Sea
2016The Red Sea is an arid environment, without riverine inputs, oligotrophic waters and extreme temperature and salinity. Avicennia marina is the dominant vegetation in the shores of the Red Sea. However, little is known about their distribution, dynamics, and services. Therefore, the aim of this Ph.D.
