The heat is on: Observations and trends of heat stress metrics during Florida summers

Extreme heat is annually the deadliest weather hazard in the U.S. and is strongly amplified by climate change. In Florida, summer heat waves have increased in frequency and duration, exacerbating negative human health impacts on a state with a substantial older population and industries (e.g., agriculture) that require frequent outdoor work. However, the combined impacts of temperature and humidity (heat stress) have not been previously investigated. For eight Florida cities, this study constructs summer climatologies and trend analyses (1950–2020) of two heat stress metrics: heat index (HI) and wet bulb globe temperature (WBGT). While both incorporate temperature and humidity, WBGT also includes wind and solar radiation, and is a more comprehensive measure of heat stress on the human body. With minor exceptions, results show increases in average summer daily maximum, mean, and minimum HI and WBGT throughout Florida. Daily minimum HI and WBGT exhibit statistically significant increases at all eight stations, emphasizing a hazardous rise in nighttime heat stress. Corresponding to other recent studies, HI and WBGT increases are largest in coastal subtropical locations in Central and South Florida (i.e., Daytona Beach, Tampa, Miami, Key West), but exhibit no conclusive relationship with urbanization changes. Finally, danger (103–124°F) HI and high (> 88°F) WBGT summer days exhibit significant frequency increases across the state. Especially at coastal locations in the Florida Peninsula and Keys, danger HI and high WBGT days now account for > 20% of total summer days, emphasizing a substantial escalation in heat stress, particularly since 2000.

Aging Bodies in Paradise: A Feminist Analysis of Key West’s Fantasy Fest

Cultural constructions of gender and age may be challenged within politically and socially progressive leisure environments, like Key West, that promote social deviance and out-group acceptance. However, this possibility receives limited scholarly attention. Addressing this gap, our study applies a framework that highlights gender and age as performances and uses interviews ( n = 77) collected in 2017 and 2018 at Key West’s Fantasy Fest, an annual carnivalesque event characterized by body displays of nudity, body paint, and costume. In this first systematic study of Fantasy Fest, data analysis revealed four themes centering on gender, age, and bodies—displaying diverse bodies; judging bodies; limiting body displays; and reinterpreting body-related norms. Key West’s cultural ideology of inclusion allowed both young and old participants to perform gender and age in ways that contributed to a more liberating environment celebrating a range of bodies—though performances were constrained by inequalities. Bodies, especially women’s, were subjected to judgments of their sexual appeal that led some, especially older women, to limit their displays. Our findings, nevertheless, suggest progressive, carnivalesque leisure environments’ potential, however fleeting or bounded, to disrupt everyday performances and broaden conceptions of gendered and aging bodies by reinterpreting the norms surrounding them.

Ground Applications of Vectobac® WDG with A1 Super-Duty Mist Sprayer® and Micronair® AU5000 Atomizer for Suppression of Aedes aegypti Populations in the Florida Keys

ABSTRACT Since 2011, the Florida Keys Mosquito Control District (FKMCD) has used the WALS® application strategy with VectoBac® WDG containing Bacillus thuringiensis israelensis via helicopter in Key West for the control of Aedes aegypti larval populations. In 2018, FKMCD conducted a study to determine the effectiveness of using a trailer-mounted A1 Super Duty Mist Sprayer® (A1 Mist Sprayers) with a Micronair® AU5000 (Micron Group) atomizer to apply VectoBac WDG by ground at the rate of 0.5 lb/acre (0.56 kg/ha). Bioassay cups were placed in a residential area encompassing open, moderate, and heavy cover scenarios between 0 and 300 ft (0–91.44 m) perpendicular to the spray line. An application rate of 0.5 lbs/acre (0.56 kg/ha) was used. Bioassay cups were collected after application and returned to the laboratory where 100 ml of distilled water and 10 F1 generation Ae. aegypti larvae were added. Laval mortality was monitored at 2, 4, and 24 h. Three separate runs were completed during the summer of 2018. Average larval mortality at 24 h was >90%. The field trial demonstrated sufficient efficacy to introduce this method of larviciding into operational use.

Chelonia mydas fibropapillomatosis in Baie Blanche, Tintamarre Island Saint Martin (FWI), an environmental sciences and veterinary cross-analysis

Chelonia mydas’s fibropapillomatosis is a panzootic neoplastic disease that has been affecting the species since 1930’s, starting in Key West Florida USA. Most likely induced by the Chelonian HerpesVirus 5 (ChHV5), fibropapillomatosis has been recorded as affecting all species of marine turtles, provoking the growth of malignant external and internal round shaped tumors to marine turtles, that share numerous genomic similarities with human cancers. This research focuses on the two pristine bays of Tintamarre island in Saint Martin (French West Indies), Baie Blanche and Lagon, where the early stage of fibropapillomatosis has been observed affecting juvenile Chelonia mydas resident of Tintamarre. The results obtained when cross-analyzing the environmental monitoring and studies performed of Tintamarre island and a veterinary health assessment of Chelonia mydas juvenile and sub-adult marine turtles of Baie Blanche, bring a different perspective to the environmental pressures that may be responsible of the expression of the disease in Chelonia mydas. Macro-algae and Cadmium (Cd) contamination of marine turtles habitat and foraging grounds are environmental parameters that are found as possibly inducing fibropapillomatosis clinical expression in Tintamarre in this research, concurring with previous publications findings. Tintamarre island in Saint Martin (FWI) is a key site to study pertaining to marine turtle fibropapillomatosis.

Resistance to permethrin alters the gut microbiota of Aedes aegypti

Insecticide resistance has emerged as a persistent threat to the fight against vector-borne diseases. We compared the gut microbiota of permethrin-selected (PS) strain of Aedes aegypti relative to the parent (KW) strain from Key West, Florida. Bacterial richness but not diversity was significantly higher in PS strain compared to KW strain. The two mosquito strains also differed in their gut microbial composition. Cutibacterium spp., Corynebacterium spp., Citricoccus spp., Leucobacter spp., Acinetobacter spp., Dietzia spp., and Anaerococcus spp. were more abundant in PS strain than in KW strain. In contrast, Sphingomonas spp., Aquabacterium spp., Methylobacterium spp., Flavobacterium spp., Lactobacillus spp., unclassified Burkholderiaceae and unclassified Nostocaceae were more abundant in KW strain compared to PS strain. PS strain was enriched with propionate metabolizers, selenate reducers, and xylan, chitin, and chlorophenol degraders while KW strain was enriched with sulfur oxidizers, sulfur metabolizers, sulfate reducers and naphthalene and aromatic hydrocarbons degraders. These findings demonstrate an association between the gut microbiota and insecticide resistance in an important vector species and sets the foundation for future studies to investigate the contribution of gut microbiota to evolution of insecticide resistance in disease vectors.

ELIZABETH BISHOP, ARMÁRIO E GOZO: DINÂMICAS DO EROTISMO

Em carta e nos poemas O banho de xampu e Canção do tempo das chuvas, Elizabeth Bishop (2006, 2011 e 2012) representa Key West, na Flórida, e a Casa de Samambaia, em Petrópolis, no Rio de Janeiro, retratando-os como lugares de maior acolhimento para sua subjetividade e sexualidade. Nesses textos, a poeta revela um jogo erótico com o lugar, dinamizado pelo soterramento de sua intimidade em descrições, aparentemente, neutras da realidade. Essa dinâmica sugere há existência de um jogo libidinal entre a insinuação de um segredo e, ao mesmo tempo, a manutenção de seu sigilo. Dona de uma poética do armário (SEDGWICK, 2007), Bishop, uma mulher lésbica, nesses textos, aponta para experiências íntimas, marcadas pela jouissance, pela relação erótica com o lugar (BATAILLE, 1987). Neste ensaio, proponho pensar esse jogo, destacando expressões de gozo simulacradas na relação com o ambiente, um gozo que se realiza à revelia da opressão, da hostilidade de gênero e do preconceito (LUGONES, 2019). PALAVRAS-CHAVE: Elizabeth Bishop. Representações da Intimidade. Erotismo. Armário. Gozo.

Hurricane Irma–Navy's Displaced Vessel and Oil Spill Response

On the evening of 09–10 September 2017, the Florida Keys were pummeled by Hurricane Irma - a Category 4 storm that was the fifth-costliest hurricane to hit mainland United States, causing an estimated $50 billion in damages, and 34 lives lost in Florida alone. In the Keys, approximately 1350 boats were destroyed or damaged, and approximately 2000 boats were removed from the waters and shorelines from a Unified Command (UC) comprised of U.S. Coast Guard, EPA and Florida Fish and Wildlife Conservation Commission funded from the Federal Emergency Management Agency (FEMA), under an ESF10 Mission Assignment to remove those vessels displaced from the storm where they had sunk, submerged, or been stranded along the shoreline. On September 28, 2017, the UC decided that boats that were on federal property were the responsibility of that agency to manage, and furthermore, since each of these boats had batteries and in most cases fuel on board they posed an immediate hazardous substance and/or oil spill threat, so requested that Navy undertake operations immediately as the lead FOSC to address each of the vessels sunk, submerged, stranded or otherwise displaced on Navy property in the Key West area. On October 1, 2017, the Navy On-Scene Coordinator Representative (NOSC-R) from Navy Region Southeast (NRSE) deployed to Naval Air Station Key West (NASKW) to manage the response. Once adequate funds were identified and secured, NRSE contracted Navy Supervisor of Salvage (SUPSALV), who quickly arrived on-scene with a contracted private salvor. Operations fell into several stages: locating each vessel on NASKW property and determining its condition; identifying each owner/representative; retrieval and temporary storage of each vessel or its remains on Navy property; contacting vessel owners/representatives to making arrangements for owner or insurance company to retrieve the vessel, or surrender it to Navy custody for final destruction at Navy's expense. A number of challenges arose during this response: finding adequate funds at the end of a fiscal year for an un-programmed multi-million dollar project; identifying owners and contact information; negotiating final disposition of each vessel; allowing owners access to vessels stored on Navy property. After 9 weeks of vessel location and identification, and owner notifications, 15 vessels were retrieved by owners, 13 vessels were towed away or otherwise removed by owner insurance companies, and 52 were barged off to a boatyard for final destruction at Navy's expense. In total, $3M was spent by Navy for this operation.

Assessing Marginal Shallow-Water Bathymetric Information Content of Lidar Sounding Attribute Data and Derived Seafloor Geomorphometry

Shallow-water depth estimates from airborne lidar data might be improved by using sounding attribute data (SAD) and ocean geomorphometry derived from lidar soundings. Moreover, an accurate derivation of geomorphometry would be beneficial to other applications. The SAD examined here included routinely collected variables such as sounding intensity and fore/aft scan direction. Ocean-floor geomorphometry was described by slope, orientation, and pulse orthogonality that were derived from the depth estimates of bathymetry soundings using spatial extrapolation and interpolation. Four data case studies (CSs) located near Key West, Florida (United States) were the testbed for this study. To identify bathymetry soundings in lidar point clouds, extreme gradient boosting (XGB) models were fitted for all seven possible combinations of three variable suites—SAD, derived geomorphometry, and sounding depth. R2 values for the best models were between 0.6 and 0.99, and global accuracy values were between 85% and 95%. Lidar depth alone had the strongest relationship to bathymetry for all but the shallowest CS, but the SAD provided demonstrable model improvements for all CSs. The derived geomorphometry variables contained little bathymetric information. Whereas the SAD showed promise for improving the extraction of bathymetry from lidar point clouds, the derived geomorphometry variables do not appear to describe geomorphometry well.
