A review of current salt marsh management issues in Florida.
For the past decade, salt marsh management in Florida has been a central issue in attempts to reconcile mosquito control and natural resource interests. Progress has been made in trying to maintain effective mosquito control while protecting and enhancing salt marsh resources primarily due to: 1) efforts by the Florida Coordinating Council on Mosquito Control and its Subcommittee on Managed Mar...
متن کاملSalt Marsh Tidal Channels
Salt marsh tidal channels are highly sinuous. For this project, field surveys and aerial photographs were used to characterize the planform of tidal channels at China Camp Marsh in the San Francisco Bay, California. To model the planform evolution, we assume that the topographic curvature of the channel centreline is a key element driving meander migration. Extraction of curvature data from a p...
متن کاملThe effect of tidal forcing on biogeochemical processes in intertidal salt marsh sediments
BACKGROUND Early diagenetic processes involved in natural organic matter (NOM) oxidation in marine sediments have been for the most part characterized after collecting sediment cores and extracting porewaters. These techniques have proven useful for deep-sea sediments where biogeochemical processes are limited to aerobic respiration, denitrification, and manganese reduction and span over severa...
متن کاملFood webs and parasites in a salt marsh ecosystem
Our mothers teach us to grill our meats " well done " and chew them thoroughly. Even if mom did not know why she insisted, both are good precautions against parasites. Parasites may be in our food, but they are not in our food webs. Is it necessary to take the precaution of considering them? In this chapter, we argue that parasites affect important properties of food webs and that it may be dif...
متن کاملMercury mobility in a salt marsh colonised by Halimione portulacoides.
The present study intends to increase the knowledge on the mobility of mercury in a salt marsh colonised by Halimione portulacoides. Mercury distribution in the sediment layers and its incorporation into the plant biomass were assessed, as well as the potential export of mercury from the contaminated area to the adjacent environment. Mercury pools in the sediments ranged from 560 to 943 mg m(-2...
