Age determination in manatees using growth-layer-group counts in bone Age determination in manatees using growth-layer-group counts in bone
Growth layers were observed in histological preparations of bones of known-age, known minimum-age, and tetracycline-marked free-ranging and captive Florida manatees (Trichechus manatus latirostris), substantiating earlier preliminary findings of other studies. Detailed analysis of 17 new case histories showed that growth-layer group (GLG) counts in the periotic bone were consistent with...

Environmental gradients and identification of wetlands in north-central Florida Environmental gradients and identification of wetlands in north-central Florida
Vegetation composition, soil morphology, and hydrology were characterized along wetland-to-upland gradients at six forested sites in north-central Florida to compare results of Federal wetland delineation methods with 3–5 yr of hydrologic data. Wetland and non-wetland identifications were supported by hydrology data in eight of nine plant communities. Lack of hydric soil indicators and...

A 7 year record of above-ground net primary production in a southeastern Mexican mangrove forest A 7 year record of above-ground net primary production in a southeastern Mexican mangrove forest
Spatial and temporal variations in net above-ground primary production (NPP) and litter turnover rate were studied, from 1987 to 1993, in a mangrove forest bordering Laguna de Terminos, Mexico. NPP, the sum of total litter fall and wood production, was measured over the entire study period in three zones in a basin forest: zone I, where Rhizophora mangle (red mangrove) occurs but...

Denitrification in a South Louisiana wetland forest receiving treated sewage effluent Denitrification in a South Louisiana wetland forest receiving treated sewage effluent
Although denitrification has the potential to reduce nitrate (NO3a??) pollution of surface waters, the quantification of denitrification rates is complex because it requires differentiation from other mechanisms and is highly variable in both space and time. This study first measured potential denitrification rates at a wetland forest site in south Louisiana before receipt of secondary...
