The objectives of this monitoring program are:
■ To detect and quantify major changes through time in the community structure and health of mangroves in the Pacific Island Region using biological and physical parameters.
■ To develop a centralised database system for mangrove monitoring for use by all
This Fifth Tuvalu National Report (5th Report) to the Convention on Biological Diversity (CBD) summarizes the nature, cultural importance, conservation status and threats changes to Tuvalu’s Biodiversity and actions taken or that need to be taken to promote the conservation and sustainable use of biodiversity since the submission of the fourth national report in 2010.
Human impacts on sand-producing, large benthic foraminifers were investigated on ocean reef flats at the northeast Majuro Atoll, Marshall Islands, along a human population gradient. The densities of dominant foraminifers Calcarina and Amphistegina declined with distance from densely populated islands. Macrophyte composition on ocean reef flats differed between locations near sparsely or densely populated islands. Nutrient concentrations in reef-flat seawater and groundwater were high near or on densely populated islands.
