Contrary to stereotypes of proto-Athapaskan culture as simplistic and archaic, evidence points to a sophisticated web of late prehistoric Asian-Athapaskan interactions. A holistic assessment of Athapaskan migrations in the context of the transpacific Dene-Yeneseian phylum (the largest, fastest pedestrian language spread on earth) sees Athapaskan-Asian connections (in language, technology, DNA, social organization, etc.) as reflecting profound large-scale cultural-historical processes whose implications have yet to be grasped. Current understanding is that Athapaskans slowly migrated south in response to volcanic eruptions in southwest Yukon Territory after circa 200 and 800 CE. Yet problems remain, notably the archaeological...

Successful conservation strategies in the face of climate change will require careful consideration of how changing climate will affect wildlife and habitats. Development of innovative, data-driven, accessible tools will assist in understanding and planning for those effects. This project was funded to (1) develop climate envelope models and associated prediction maps for 26 federally threatened and endangered terrestrial (T&E) vertebrate species occurring in peninsular Florida, (2) provide a technical guidebook for use and interpretation of climate envelope models, (3) develop visualization and social networking tools that will allow natural resource managers and the general public to view our models, and (4) create...

In 2012, the South Atlantic Landscape Conservation Cooperative (SALCC) began development of its process to select natural resource indicators and targets as specific landscape scale measures of success for natural resources. An indicator was defined by the SALCC as a metric designed to inform easily and quickly about the conditions of a system, where as a target is a numeric goal established for an indicator. Recommendations were made to the SALCC steering committee in March to recommend indicators for aquatic and terrestrial ecosystems. Recommendations were based on input from 235 experts in marine, freshwater and terrestrial resources in the SALCC geography and adjacent LCCs. Indicator recommendations were considered...

This dataset provides morphological and blood-derived physiological data from invasive Burmese pythons (Python bivittatus) captured in Florida. Data were collected on pythons at capture in the field and in varying lengths of time in captivity. Samples were collected immediately at handling (baseline) and 1 hour post-restraint. Physiological data include circulating corticosterone hormone levels, functional immune assays, and blood cell counts. Also included is R code ( Python_captivity_capture_code.R ) to replicate analyses used in the publication "Scales of Stress: Effects of capture and captivity in an invasive snake". For reference, the following data files are relevant to each section of the corresponding manuscript:...

Digestive tract contents were identified to provide an account of Burmese python diet. Diet contents came from 1716 pythons collected by cooperators during 1995-2020 from public and private lands across southern Florida, primarily within the Greater Everglades Ecosystem. Burmese pythons consumed 76 species of fauna across three taxonomic classes (Aves, Mammalia, and Reptilia).
ABSTRACT: Fire severity can be defined as the amount of biomass combusted by wildfire. Stored carbon (C) and nitrogen (N) are emitted into the atmosphere as wildfires consume vegetation and soil organic layers, thus C and N emissions should be related to fire severity. Since boreal forests store 30% of the world's terrestrial C and are subject to high-intensity, stand-replacing wildfires, it is critical to be able to estimate C fluxes from wildfires. Furthermore, quantifying fire severity is important for predicting post-fire vegetation recovery and future C sequestration. We reconstructed pre-fire organic soil layers and quantified fire severity levels from the 2004 wildfires in Interior Alaska with the adventitious...
This proposal outlines a collaborative regional effort to build a South Atlantic Ecosystem Model that will facilitate the connection of inland and coastal marine management strategies and actions to potential resource and economic impacts in estuarine and coastal marine environments, with the following two goals: 1. Improve and Expand the Functionality of the South Atlantic Landscape Conservation Cooperative Blueprint: The SALCC Blueprint is unique in its ability to connect across terrestrial, freshwater, and marine systems. Unfortunately, the availability of and quality of current models connecting impacts across those ecosystems are a major barrier for modeling efforts and Blueprint Users. Improving these models...

The proposed project focuses upon two major goals:1. Designate Priority Amphibian and Reptile Conservation Areas (PARCAs) in the South Atlantic Landscape, and develop an adaptive management plan for those areas.2. Determine whether PARCAs provide an effective strategy for integrated, long-term conservation of biodiversity and cultural resources in the South Atlantic Landscape; and develop a comprehensive biodiversity protection plan for the SALCC.To achieve these goals, we have identified the following objectives:Objective 1. Identify areas within the SALCC that are vitally important to preserving the rich diversity of amphibians and reptiles in the region, focusing upon rare species distribution, diversity, and...

Problem Almost 1900 public, private, and commercial waste-water treatment plants (WWTPs), many located upstream of drinking water intakes or within tributaries to water-supply reservoirs, are permitted to release effluents into surface- or ground-waters across New York State. More than 150 facilities have New York State SPEDES permits to discharge waste waters in the New York City East of Hudson and West of Hudson Water Supply Watersheds (NYC Watersheds), which provide drinking water to more than nine million people in and around New York City. Some common waste water treatment plant (WWTP) contaminants (e.g., polycyclic musks, alkylphenols, and estradiol) can cause estrogenic or androgenic changes in the reproductive...

This project was funded to understand how, where, and why outputs from landscape connectivity models vary, and to suggest approaches to increase comparability and interoperability of models across Landscape Conservation Cooperative boundaries. We began by compiling metadata from 73 landscape connectivity modeling projects into an online, editable spreadsheet. Using spatial data from a subset of studies included in the database, we conducted an uncertainty analysis to understand how much spatial variation there was among predictions from different landscape connectivity models. Raw outputs from the original models showed relatively little overlap, averaging about 3% across all pairs of studies. However, when a common...
