title: Oregon spotted frog (Rana pretiosa) observations in Oregon (ver. 6.0, March 2025)

description: This dataset contains information from surveys conducted 2016-2024 by USGS as part of an ongoing Oregon spotted frog (Rana pretiosa) monitoring effort in Oregon. USGS research activities 2016-2024 were divided into seven study design categories: breeding (egg mass counts), mid-level (visual encounter surveys for occupancy monitoring), apex (mark-recapture), telemetry, trapping, water quality (skin microbiome swabbing), and genetics (egg mass embryo or toe-clip tissue samples). Data consist of Oregon spotted frog observations aggregated by date, location, life stage, sex, and project. These data were compiled from multiple studies employing different survey methods, thus we caution users that counts are not directly comparable among projects; any counts may represent multiple detections of the same individual.

title: Stomatal Distribution and Post-fire Recovery: Intra- and Interspecific Variation in Plants of the Pyrogenic Florida Scrub, 2023-2024

description: Premise of the study: Amphistomy is the presence of stomata on both leaf surfaces. This distribution of stomata can increase photosynthesis, but is relatively infrequent, which is often attributed to high costs such as water loss. This study takes place in the Florida scrub- a hot, dry, shrub-dominated habitat that naturally experiences fire. However, decades of anthropogenic suppression and the reintroduction of controlled burns has created varied fire regimes across the region. In this study, we investigated the links between amphistomy and fire by determining (1) how common the trait is in this habitat, and (2) within-species variation before and after experimental fire, and across a time-since-fire gradient (0.25 - 50 years).  
 Methods: We (1) surveyed 116 plant species across scrub habitats for amphistomy presence, and  (2) experimentally and observationally investigated intraspecific variation in stomatal traits in response to fire for two post-fire resprouting species of palmetto, Serenoa repens and Sabal etonia (Arecaceae).  
 Key results: Amphistomy was present in 62.9% of all surveyed species and 85.7% of post-fire obligate reseeders, suggesting amphistomy may be beneficial in this group and in the Florida scrub conditions. The stomatal ratio (upper/total stomatal density) was generally stable in response to fire. Stomatal density decreased following fire in S. etonia, with both species experiencing high variation in the post-fire years.  
 Conclusions: Amphistomy is common in this habitat and relatively stable within species in response to fire, while stomatal density responds plastically during postfire regrowth.

title: Plasma-Catalytic Pathways for C1 Activation and Conversion to Value-Added Fuels and Chemicals

description: The advancement of effective and selective methane (CH4) conversion processes into fuels and chemicals is critical due to the increasing availability of conventional and unconventional methane-rich gas resources (e.g., shale gas, methane hydrate, coalbed methane). These resources are often located in remote areas, far from markets, posing challenges for their utilization. Industrial methane conversion predominantly relies on indirect processes such as steam reforming, while direct one-step conversion remains limited due to the chemical inertness of C-H bonds in CH4. Overcoming this activation barrier conventionally requires high temperatures and substantial energy input, often leading to catalyst deactivation due to carbon deposition.

This dissertation explores the potential of nonthermal plasmas coupled with catalysis as an alternative approach for methane valorization. The first part of this work focuses on the low-temperature plasma-catalytic conversion of methane to aromatic hydrocarbons (benzene, toluene, and xylene) over H-ZSM-5 and Mo/H-ZSM-5 catalysts.We further investigate the dynamic nature of Mo catalytic centers under plasma stimulation, particularly their transformation into carbide phases under methane plasma conditions. In the final section, we explore plasma-driven carbon-nitrogen coupling reactions for the selective synthesis of acetonitrile, demonstrating that gallium nitride catalysts can act as a nitrogen reservoir, interacting with plasma-activated methane species to promote C-N bond formation.

Overall, this work highlights the potential of plasma-catalytic processes for methane activation and conversion, offering new pathways for low-temperature hydrocarbon synthesis while addressing the challenges of conventional catalytic approaches.

Figure 4: Excel files containing logarithmic current-voltage data for samples with the thicker AlGaN barrier, annealed at (a) 700 °C and (b) 750 °C for 30 s. Figure 5: Excel files showing the current-voltage data from the sample with 29 nm AlGaN barrier, contacts annealed at 700 °C, after processing in the context of different mechanisms. In (a), the data are processed to a Fowler-Nordheim tunnelling model, and (b) is a subset of (a). In (c) the data are processed to plot in an Arrhenius manner. In (d) the data are processed to a direct tunnelling model. (b), (c) and (d) also contain the linear fits generated by the Origin graph plotting software. Figure S1: Excel file showing current voltage data from the same sample as Figure 5, processed instead to fit a Frenkel-Poole emission model.
