Hydrological drivers of wetland vegetation community distribution within Everglades National Park, Florida

The influence of hydrological dynamics on vegetation distribution and the structuring of wetland environments is of growing interest as wetlands are modified by human action and the increasing threat from climate change. Hydrological properties have long been considered a driving force in structuring wetland communities. We link hydrological dynamics with vegetation distribution across Everglades National Park (ENP) using two publicly available datasets to study the probability structure of the frequency, duration, and depth of inundation events along with their relationship to vegetation distribution. This study is among the first to show hydrologic structuring of vegetation communities at wide spatial and temporal scales, as results indicate that the percentage of time a location is inundated and its mean depth are the principal structuring variables to which individual communities respond. For example, sawgrass, the most abundant vegetation type within the ENP, is found across a wide range of time inundated percentages and mean depths. Meanwhile, other communities like pine savanna or red mangrove scrub are more restricted in their distribution and found disproportionately at particular depths and inundations. These results, along with the probabilistic structure of hydropatterns, potentially allow for the evaluation of climate change impacts on wetland vegetation community structure and distribution.

A Tale of Two Fishes: Using Recreational Angler Records to Examine the Link Between Fish Catches and Floodplain Connections in a Subtropical Coastal River

In the tropical and subtropical wet and dry regions, maintaining natural hydrologic connections between coastal rivers and adjacent ephemeral wetlands is critical to conserving and sustaining high levels of fisheries production within these systems. Though there is a consensus that there is a need to maintain these natural connections, little is known about what attributes of floodplain inundation regimes are most important in sustaining fisheries production. Two attributes of the flood season and thus floodplain inundation that may be particularly influential to fisheries are the amplitude of the flood season (floodplain water depth and spatial extent of inundation) and the duration of the flood season (i.e., time floodplains are inundated). In mangrove-dominated Everglades coastal rivers, seasonal inundation of upstream marsh floodplains may play an important role in provisioning recreational fisheries; however, this relationship remains unknown. Using two Everglades coastal river fisheries as a model, we tested whether the amplitude of the flood season or the duration of the flood season is more important in explaining variation in angler catch records of common snook and largemouth bass collected from 1992 to 2012. We validated angler catches with fisheries-independent electrofishing conducted in the same region from 2004 to 2012. Our results showed (1) that bass angler catches tracked electrofishing catches, while snook catches were completely mismatched. And (2) that previous year's marsh dynamics, particularly the duration of the flood season, was more influential than the flood season amplitude in explaining variation in bass catches, such that bass angler catches were negatively correlated to the period time that floodplains remained disconnected from coastal rivers in the previous year, while snook catches were not very well explained by floodplain inundation terms.

The Efficacy of San Lazaro and His Manifestations: Divine Mediators of Health Within Miami's Cuban-American Santeria Community.

This study explored the origins, evolution and influence of the tradition of San Lázaro as it currently pertains to the Cuban-American Santeria community in Miami. The main argument of the study is that in the context of the contemporary religious culture of Santeria in Miami, San Lázaro is a hybrid spirit. Many manifestations of healing entities have come to merge in the person of this spirit. Though practitioners identify with specific manifestations of this spirit, the processes of transmigration have blurred the lines of deep-rooted faiths and created a fusion of meanings from disparate traditions, making San Lázaro an ambivalent personality. San Lázaro’s ambivalence is the very quality that makes him such an important Orisha. As a deity whose personalities demonstrates the combination of a diversity of qualities, including those that contradict each other, San Lázaro is deployed in a very broad range of healing context, making him a versatile Orisha. This study clarified the contrasting qualities this deity embodies and traces the socio-historical context in which the deity acquires the layers of meanings it is currently associated with. Drawing on interviews with Lázaranian worshipers [Lázarenos] in Miami and engaging in Bourdieu’s concept of Habitus, the study provided a window into the nature of the tradition of San Lázaro and how its usage is linked with the African heritage of the worshipers.
