Test of salt marsh as a site of production and export of fish biomass with implications for impoundment management and restoration Test of salt marsh as a site of production and export of fish biomass with implications for impoundment management and restoration
Salt marshes are among the most productive ecosystems in the world, and although they are thought to enhance the productivity of open estuarine waters, the mechanism by which energy transfer occurs has been debated for decades. One possible mechanism is the transfer of saltmarsh production to estuarine waters by vagile fishes and invertebrates. Saltmarsh impoundments in the Indian River...

Weak trophic interactions among birds, insects and white oak saplings (Quercus alba) Weak trophic interactions among birds, insects and white oak saplings (Quercus alba)
We examined the interactions among insectivorous birds, arthropods and white oak saplings (Quercus alba L.) in a temperate deciduous forest under 'open' and 'closed' canopy environments. For 2 y, we compared arthropod densities, leaf damage and sapling growth. Saplings from each canopy environment were assigned to one of four treatments: (1) reference, (2) bird exclosure, (3) insecticide...

An evaluation of biomarkers of reproductive function and potential contaminant effects in Florida largemouth bass (Micropterus salmoides floridanus) sampled from the St. Johns River An evaluation of biomarkers of reproductive function and potential contaminant effects in Florida largemouth bass (Micropterus salmoides floridanus) sampled from the St. Johns River
The objective of this study was to describe and compare several reproductive parameters for Florida largemouth bass (Micropterus salmoides floridanus) inhabiting the St. Johns River and exposed to different types and/or degrees of contamination. Welaka was selected as the reference site in this study because of its low urban and agricultural development, Palatka is in close proximity to...

Optimal exploitation of spatially distributed trophic resources and population stability Optimal exploitation of spatially distributed trophic resources and population stability
The relationships between optimal foraging of individuals and population stability are addressed by testing, with a spatially explicit model, the effect of patch departure behaviour on individual energetics and population stability. A factorial experimental design was used to analyse the relevance of the behavioural factor in relation to three factors that are known to affect individual...

Does bird community structure vary with landscape patchiness? A Chihuahuan Desert perspective Does bird community structure vary with landscape patchiness? A Chihuahuan Desert perspective
During the springs of 1995-1997, we studied birds and landscapes at 70 sites in the Chihuahuan Desert to assess relations between bird community structure and landscape patchiness. Within each of two spatial extents (1-kin and 2-km-radius areas centered on each site), we measured the number of patches of individual land-cover types and the total number of patches of all land-cover types...

History and ecology of mangroves in the Dry Tortugas History and ecology of mangroves in the Dry Tortugas
Dry Tortugas National Park, which includes Bush, Long, Loggerhead, Garden, and Bird Keys, is a cluster of islands and coral reefs approximately 112.9 km (70 miles) west of Key West, Florida (fig. 1). These islands were explored in 1513 by Ponce de León, who named them for the abundance of sea turtles, “tortugas,” and the lack of fresh water in the area. Historically, the Tortugas shoals...

The use of resighting data to estimate the rate of population growth of the snail kite in Florida The use of resighting data to estimate the rate of population growth of the snail kite in Florida
The rate of population growth (lambda) is an important demographic parameter used to assess the viability of a population and to develop management and conservation agendas. We examined the use of resighting data to estimate lambda for the snail kite population in Florida from 1997-2000. The analyses consisted of (1) a robust design approach that derives an estimate of lambda from...
