I used radio-telemetry to track the movements of Mangrove Cuckoos (Coccyzus minor) captured in southwest Florida. Relatively little is known about the natural history of Mangrove Cuckoos, and my goal was to provide an initial description of how individuals use space, with a focus on the size and placement of home ranges. I captured and affixed VHF radio-transmitters to 32 individuals between 20...

The concentrations of total polycyclic aromatic hydrocarbons (sigmaPAHs) and 15 individual PAH compounds in 20 surface sediments collected from four mangrove swamps in Hong Kong were analysed. sigmaPAH concentrations ranged from 356 to 11,098 ng g(-1) dry weight with mean and median values of 1992 and 1,142 ng g(-1), respectively. These values were significantly higher than those of marine bott...

The bias against mangrove areas in siting fish farms prompted a comparison of the cost structure and yield performance in upland and mangrove locations. Tools utilized included descriptive statistics, budgetary and cash flow analyses and profitability ratios. Empirical results revealed that substantial revenue could be realized from both farms. While the upland farms yielded average gross reven...

Protected areas are used to sustain biodiversity and ecosystem services. However, protected areas can create tradeoffs spatially and temporally among ecosystem services, which can affect the welfare of dependent local communities. This study examines the effect of a protected area on the tradeoff between two extractive ecosystem services from mangrove forests: cutting mangroves (fuelwood) and h...

The importance of mangrove forests in maintaining crucial ecosystem functions such as nutrient filtering, supporting coral reef fisheries, and providing storm buffers has become more evident after the tsunami that ravaged parts of Asia in December 2004 (Alongi 2002; Mumby et al. 2003; UNEP-WCMC 2006). However, these vital tropical ecosystems in the coastal inter-tidal zones, covering about 181,...

a r t i c l e i n f o Keywords: Mangrove Restoration programs Choice experiment Willingness to pay Brazil Mangrove forests are under considerable pressure in many developing countries and Brazil is not an exception to this problem. We investigate preferences for the restoration of mangrove areas in Brazil, using a choice experiment that varies the level and time of restoration. By interacting t...

BACKGROUND Since Spartina alterniflora (simplified as Spartina) has strong ecological competitiveness and rapid growth, it has been introduced and living in the coastal wetland regions of China for more than 30 years. Taking coastal wetland in the Beibu Gulf of south China as an example, the effects of Spartina invasion on soil quality were investigated to provide scientific basis for soil mana...

Mangroves are among the most well described and widely studied wetland communities in the world. The greatest threats to mangrove persistence are deforestation and other anthropogenic disturbances that can compromise habitat stability and resilience to sea-level rise. To persist, mangrove ecosystems must adjust to rising sea level by building vertically or become submerged. Mangroves may direct...

As a first step in developing classification procedures for remotely acquired hyperspectral mapping of mangrove canopies, we conducted a laboratory study of mangrove leaf spectral reflectance at a study site on the Caribbean coast of Panama, where the mangrove forest canopy is dominated by Avicennia germinans, Laguncularia racemosa, and Rhizophora mangle. Using a highresolution spectrometer, we...
