Quantifying ecosystem-level processes that drive community structure and function is key to the development of effective environmental restoration and management programs. To assess the effects of large-scale aquatic vegetation loss on fish and invertebrate communities in Florida estuaries, we quantified and compared the food webs of two adjacent spring-fed rivers that flow into the Gulf of Mexico. We constructed a food web model using field-based estimates of community absolute biomass and trop...

A decline in submerged aquatic vegetation (SAV) within Florida's spring-fed, thermal refuges raises questions about how these systems support winter foraging of Florida manatees (Trichechus manatus latirostris). We analyzed telemetry data for 12 manatees over seven years to assess their use of Kings Bay, a winter refuge with diminished SAV. After accounting for the effect of water temperature, we hypothesized that the number of trips out of Kings Bay would increase and the time wintering manatee...

Abstract The mutualistic relationship between dinoflagellates in the genus Symbiodinium microadriaticum and animals in the phylum Cnidaria, specifically corals, make up one of the most well-known symbioses in the marine environment. The nature of the relationship is such that these symbiotic algae provide products of photosynthesis to their cnidarian hosts, while the algae are afforded refuge within the endodermal cells of the host. Use of the model system Cassiopea xamachana (a.k.a. the ‘upside...

ABSTRACTFrench Polynesia’s economy is largely dependent on the black pearl industry and associated export revenues. Accordingly, there is a need to understand fully the factors that influence quality and price of pearls – and threats to future sustainability. Focus, thus far, has been on production practices that affect pearl characteristics and quality. Although there is a generally accepted hierarchy in the characteristics of black pearls that determine quality and price, the contributory valu...

The status of the West Indian manatee [Trichechus manatus (Linnaeus, 1758)] remains enigmatic. The International Union for Conservation of Nature classifies the species as “Vulnerable” and the two subspecies [T. m. manatus (Linnaeus, 1758) and T. m. latirostris (Harlan, 1824)] as “Endangered.” The U.S. Fish and Wildlife Service now classifies West Indian manatees as “Threatened” primarily due to increased numbers of T. m. latirostris. Fully resolving the status of the species will require a bett...

The use of aquatic mammals as bait to enhance the harvest of fisheries species has garnered little attention by the scientific and conservation communities, often receiving only brief mention in reports focused on the human consumption or bycatch of aquatic mammals. A number of studies, however, highlight the negative impact of this practice on affected mammal populations. A systematic review of relevant literature published since 1970 yields new insight into the scope of the issue. Findings ind...

AbstractAn aggregation of Suwannee Cooters (Pseudemys concinna suwanniensis) prompted an investigation of their effects on vegetation in Blue Spring, a 2nd-magnitude spring in Gilchrist County, Florida. We counted turtles and documented % cover and wet biomass of vegetation in September and October 2013. The maximum mean density of turtles (1566 ± 319 turtles/ha) was recorded near the spring vent during the 1st survey. Mean density among all reaches of the spring run decreased from 421 ± 133 to ...
