Infaunal communities adjacent to different coral types, including reef-building scleractinian corals and individual colonies of octocorals, are known to differ from background non-coral soft-sediment communities, often exhibiting higher macrofaunal densities and distinct community structure. However, the coral types have different morphologies, which may modify the adjacent sediment communities in discrete ways. Here we address two main questions: 1) how infaunal communities adjacent to deep-sea corals and their associated...

We experimentally evaluated salinity tolerance for three freshwater mussel species (Utterbackia imbecillis, Elliptio jayensis, and Glebula rotundata). Mussels were transferred abruptly from well water to one of five treatments (0 [control], 6, 12, 18 or 24 parts per thousand [ppt]) with no acclimation. Utterbackia imbecillis survived on average about 2 days at treatments ≥ 6 ppt, while Elliptio jayensis survived slightly longer (about 4 days). Glebula rotundata was most tolerant to salinity, surviving as well at 6 and 12 ppt as it did in the control. Additionally, G. rotundata...

Temperature is an important factor in understanding biogeography and species composition. In south Florida, non-native fishes’ tolerance to low temperatures is a critical factor in delineating their geographic spread. We provide a literature review summarizing the current state of knowledge of low-temperature tolerances for all seventeen non-native fishes that have been found in Everglades National Park.

Several deep-sea coral habitats were impacted by the 2010 Deepwater Horizon spill, and recovery of associated sediment communities may take several years. While spill-associated organic enrichment may lead to increased abundances of tolerant taxa, toxic effects of the spill may lead to declines in sensitive groups. However, temporal variability in coral-associated sediment macrofauna is unknown and represents an important consideration for post-spill community assessments. Here we examine how the macrofaunal communities change over time at impacted and reference sites. From 2010 to 2016, we examined macrofaunal communities at multiple...

The refuge is within the impact area of the Picayune Strand Restoration Project (PSRP), a large-scale hydrologic restoration project in southwest Florida that was authorized by the U.S. Congress in 2007. Vegetation transects were located in the following wetland types on the refuge: brackish marsh, salt marsh, and transition marsh. Data from vegetation transects established in nearby areas outside of the PSRP impact area, in Fakahatchee Strand Preserve State Park (FSPSP) and Big Cypress National Preserve (BICY), are also included.

Environmental DNA (eDNA) analysis is a newly-developed technique used to non-invasively detect cryptic or low-density species, or those that are logistically difficult to study. Genetic material shed into the environment through tissue and body fluids is concentrated from water samples and analyzed for the presence of target species eDNA. To help delineate bullseye snakehead’s geographic range, we developed and validated a species-specific eDNA assay for both quantitative and droplet digital PCR (ddPCR). We then used ddPCR to assess 16 locations in southeast Florida... Categories: Data; Tags: Aquatic Biology, Ecology, Everglades, Genetics, Southern Florida, All tags...

These data were used to evaluate the non-lethal impacts of a gill sampling protocol to assess gravidity of freshwater mussels. Data were collected every four weeks, or as weather permitted, to be able to monitor the reproductive status of each mussel every month of the year. The dataset includes unique tag numbers to identify specific female mussels captured and recaptured during this study. Genus and species were identified, and the gravidity status was evaluated for each individual mussel.

Can biotic resistance explain the small geographic range of non-native croaking gourami Trichopsis vittata (Cuvier, 1831) in Florida, USA? In this report, we evaluate this hypothesis for croaking gourami Trichopsis vittata, a non-native species that has established a reproducing population, but has not successfully spread beyond its very small (5 km2) range. We suspected the inability of T. vittata to colonize new habitats may be due to biotic resistance by the native eastern mosquitofish Gambusia holbrooki.

While their contribution to trophic linkages and dynamics in coral reef systems has received considerable attention, the role of linkages involving their parasites has not. As both consumers of fish tissue and prey to microcarnivores, external parasites can play a significant role in trophic transfer between the primarily algae-based food source and the broader coral reef community. Stable isotope analysis is a common tool for studying trophic linkages, which can be used for studies involving parasites. These data were collected to examine the stable isotope ecology (13C and 15N) of copepod (Caligus atromaculatus) and...
