Molecular and morphological evidence has shown that the African slender-snouted, or sharp-nosed, crocodile Mecistops cataphractus (Cuvier, 1824) is comprised of two superficially cryptic species: one endemic to West Africa other Central Africa. Our ability characterize species compromised by complicated taxonomic history lineage overlapping ranges variation in distinguishing features. The name M. was evidently originally based on material, but holotype now lost. Although types exist for...
Abstract We describe two new osteolaemine crocodylids from the Early and early Middle Miocene of Kenya: Kinyang mabokoensis tax. nov. (Maboko, 15 Ma) tchernovi (Karungu Loperot, 18 Ma). Additional material referable to is known Chianda Moruorot. The skull was broad dorsoventrally deep, genus can be diagnosed based on combined presence a partial overbite, subdivided fossa for lateral collateral ligament surangular, maxilla with no more than 13 alveoli. Phylogenetic analyses morphological...
Abstract Brochuchus is a small crocodylid originally based on specimens from the early Miocene of Rusinga Island, Lake Victoria, Kenya. Here, we report occurrences several and middle sites. Some are Victoria region, others in Turkana Basin. Specimens Maboko locality form basis new species, parvidens , which has comparatively smaller maxillary alveoli. Because alveoli, teeth appear to be more widely spaced species. We also provide revised diagnosis for its type B . pigotti A phylogenetic...
Operational ecological forecasting is an emerging field that leverages models in a new, cross-disciplinary way – using real-time or nearly climate forecast to project near-term ecosystem states. These applications give decision-makers lead time anticipate and manage state changes degrade functions directly impact humans. The Everglades Forecasting model (EverForecast) operational designed specifically for conservation management purposes including water management. It provides up six-month...
During the Cretaceous and Paleogene periods, Earth experienced tectonic climatic changes, which included continental drift following breakup of supercontinents Gondwana Laurasia, end-Cretaceous mass extinction event, several events, including Paleocene–Eocene Thermal Maximum Middle Eocene Climatic Optimum. In response to increased temperatures vacancies ecospace left by non-avian dinosaurs, mammal reptile lineages that survived into underwent immense evolutionary radiations led...
Nile Monitors (Varanus niloticus) are large (up to 2.4 m in length), semiaquatic, carnivorous lizards native Sub-Saharan Africa. reported from southeastern Florida near the Homestead Air Reserve Base Miami-Dade County, around Southwest Ranches Broward and a reproducing population along C-51 canal Palm Beach County. This study characterizes diet of removed counties. In 2012, Fish Wildlife Conservation Commission staff University researchers began conducting monthly boat surveys driving...
We examined body condition (using Fulton’s K with snout-vent length and weight) for 482 American alligators (Alligator mississippiensis) collected from 14 aquatic sites in Florida 2011 2012. An information-theoretic approach using Akaike information criterion (AIC) was used to select the best models alligator a suite of seven candidate created combinations trophic state (oligotrophic, eutrophic, hypereutrophic), sex, alligators/km. Our top model included alligators/km indicating that...
Reptiles exhibit a wide diversity of social systems, and while not very common, exclusive consensual mating relationships have been documented in several lizard species including lizards from the Teiidae family. Here, we document dyadic movement behavior between an adult male female Salvator merianae (Argentine Black White Tegu), large, omnivorous native to Brazil, Uruguay, eastern Paraguay, Argentina that became established as invasive Florida, southeastern United States. Using global...
The discovery of cryptic biodiversity has blossomed under the advancements genetic techniques, but species identification via morphology remains crucial to effective conservation efforts. In this study, we tested use continuous cranial shape variation in distinguishing two living Mecistops: West African slender-snouted crocodile (M. cataphractus) and Central leptorhynchus). Using a combination geometric morphometric characters ratios linear measurements, identified statistically significant...
Giant dipole resonance (GDR) \ensuremath{\gamma} rays were measured in coincidence with reaction fragments $^{58}\mathrm{Ni}$${+}^{165}$Ho at 368 MeV where deep inelastic scattering and quasifission dominate the reaction. The spectrum associated events is well fitted by statistical cooling of projectile target-like close to equal initial energy sharing. described emission from fission alone, only weak evidence for GDR mononucleus. A 1\ensuremath{\sigma} limit...

ABSTRACT Field work protocols in the recovery of vertebrate fossils can vary between sites, and also within due to differing researcher goals. Disparate priorities affect resulting collections terms species richness, size distribution, specimen completeness, taphonomic condition, aesthetic value. We examined paleoecological data, form bone surface modifications (e.g., abrasion, feeding traces, etc.), from a single site worked by multiple collectors determine sensitivity this type data...

Several data loggers deployed to monitor temperature and humidity of Crocodylus acutus (American crocodile) nests in South Florida could not be located after hatching. One badly damaged logger was retrieved, providing insight into the possible fate others. Using a taphonomic approach, we identified numerous indentations, consistent with crocodylian bite marks, inconsistent potential mammalian or squamate bites. It seems most likely that by nesting C. rather than during attempted nest...
