Climate change remains a primary threat to inland fishes and fisheries. Using topic modeling to examine trends and relationships across 36 years of scientific literature on documented and projected climate impacts to inland fish, we identify ten representative topics within this body of literature: assemblages, climate scenarios, distribution, climate drivers, population growth, invasive species, populations, phenology, physiology, and reproduction. These topics are largely similar to the output from artificial intelligence application (i.e., ChatGPT) search prompts, but with some key differences. The field of climate impacts on fish has seen dramatic growth since the mid-2000s with increasing popularity of topics...

Freshwater is a critical driver for island ecosystems. In Hawai‘i, though rainfall intensity has increased, total rainfall has been on the decline for the last two decades and, as a result, reduced streamflow. Climate change has fundamentally altered the water cycle in these tropical islands. The changes in dynamic patterns of streamflow could result in temporal and spatial differences in the fluvial, estuarine, and coastal habitats. These habitats support the nine native aquatic species in Hawaii at different stages of their amphidromous life cycle. To examine how changes in streamflow regime has impacted habitat quality for native migratory aquatic species, an ongoing project has examined statewide long-term stream...
This resource is a series of reports describing the observed and projected changes in climate for states in the Northeast United States. States covered in this report include: Connecticut, Deleware, Massachusetts, Maryland-District of Columbia, Maine, New Hampshire, Jew Jersey, New York, Pennsylvania, Rhode Island, Virginia, Vermont, and West Virginia. This information can be incorporated into state wildlife action plans (SWAPs).
Frequent, low-intensity wildfires were once widespread across the Southeast US, which led to a reduction in unchecked vegetation growth that provided fuel for high-intensity fires. Both intentional and unintentional fire suppression and land-use changes have reduced many of these wildfires and the fire-adapted habitats in the region over time. This loss of frequent low-intensity wildfires on the landscape also increases the severity of wildfires due to fuel buildup and the encroachment of woody species. The remaining habitats and their native species (many of which are of conservation concern) are now almost completely dependent on prescribed burns for their persistence and survival. Successful application of fire...
Remote camera data on snow presence, snow depth, and wildlife detections on Moscow Mountain in Latah County, ID, USA. Reconyx Hyperfire I and Hyperfire II cameras were used and set to take hourly timelapse images and motion-triggered images. The cameras were deployed from October 2020 - May 2021. Snow presence was assessed up to 15 m from the camera. Snow depth was measured using virtual snow stakes created with the edger R package created by the author. Wildlife were marked as present in all photos in which they appear, and new individuals were counted. Snow density was collected using a federal or prairie snow sampler. Snow hardness was collected using a ram penetrometer. Solar radiation was calculated using hemispherical...
We collected snow density measurements at camera sites from December 2020 - April 2021, at the same time as snow hardness measurements. We took measurements every few weeks as logistics allowed. We took samples near the camera site in snow visually similar to the snow in the camera viewshed (the geographical area that is visible from a location) to prevent snow conditions from being disturbed beyond normal camera deployment. We took snow density samples using a homemade prairie sampler in snow depths < 100 cm and using a federal snow sampler in snow depths > 100 cm. The sampler was inserted into the snow to remove a snow core. We retained the core if the depth of snow in the sampler was at least 90% of the actual...
Indigenous Knowledge (IK) is increasingly involved in the contemporary management of natural resources. Tribal wildlife management programs in the United States may be uniquely positioned to effectively and ethically integrate their IK. While a narrow focus on the body of IK and a particular management activity may suffice for project-level integration efforts, herein we consider how IK integration at the programmatic level may be best supported. We propose a holistic conceptual framework of preconditions including sovereignty, the North American Model management, funding, cultural resources, stakeholder support, and programmatic leadership. We assess the current status and common challenges with each precondition...

Abstract (from Springer): Climate change is altering species’ range limits and transforming ecosystems. For example, warming temperatures are leading to the range expansion of tropical, cold-sensitive species at the expense of their cold-tolerant counterparts. In some temperate and subtropical coastal wetlands, warming winters are enabling mangrove forest encroachment into salt marsh, which is a major regime shift that has significant ecological and societal ramifications. Here, we synthesized existing data and expert knowledge to assess the distribution of mangroves near rapidly changing range limits in the southeastern USA. We used expert elicitation to identify data limitations and highlight knowledge gaps for...

Understanding age and growth are important for fisheries science and management; however, age data are not routinely collected for many populations. We propose and test a method of borrowing age–length data across increasingly broader spatiotemporal levels to create a hierarchical age–length key (HALK). We assessed this method by comparing growth and mortality metrics to those estimated from lake–year age–length keys ages using seven common freshwater fish species across the upper Midwestern United States. Levels used for data borrowing began most specifically by borrowing within lake across time and increased in breadth to include data within the Hydrologic Unit Code (HUC) 10 watershed, HUC8 watershed, Level III...

Aim To provide the first regional analysis of contemporary drivers of Pacific Island fire regimes. Location Islands of Palau, Yap, Guam, Rota, Tinian, Saipan, Chuuk, Pohnpei, Kosrae. Time Period 1950-present. Methods We used land cover, soil maps and contemporary fire histories to (1) describe the relationships among fire activity, vegetation, rainfall and island geography and population; (2) examine the spatial associations of forest and savanna vegetation with respect to fire and soil types; and (3) link fire and savanna distribution to intra-annual and inter-annual rainfall variability. Results Savanna extent was positively correlated with island age and the range of mean monthly rainfall. The percent of area...

Conservative agricultural management strategies pursue long-term ecological benefits through practices such as no-tillage, cover crop, and inherent soil properties management. Farmers, however, are often hesitant to adopt such practices due to lack of experience, initial expense, and concern for low crop productivity. Overcoming this barrier requires novel approaches, such as effectively managing the soil microbiome to attain high productivity at a low cost, especially in a semi-arid region. To study the potential of conservation agriculture, we investigated components of soil bacterial community and rhizobial diversity in long-term experimental cotton fields divided into conventional tillage monoculture systems...

The data contained in child items of this page were developed to support the Species Status Assessments conducted by the U.S. Fish & Wildlife Service and conservation planning for State, Federal, and non-government researchers, managers, landowners, and other partners for five focal herpetofauna species: gopher tortoise (Gopherus polyphemus), southern hognose snake (Heterodon simus), Florida pine snake (Pituophis melanoleucus mugitus), gopher frog (Lithobates capito), and striped newt (Notophthalmus perstriatus). These data were developed by the USGS Cooperative Fish & Wildlife Research Unit at the University of Georgia in collaboration with other partners. The three child items contain the following data: (1)...
An estimated 50–80% of North America’s ducks use the millions of wetland basins in the Prairie Pothole Region as breeding habitat. The U.S. Fish and Wildlife Service (USFWS) National Wildlife Refuge System has conserved approximately 1.3 million hectares of grasslands and wetlands in the United States portion of the Prairie Pothole Region with the primary purpose to support breeding duck habitat. A major assumption inherent to the current conservation approach is that wetlands that have historically provided the highest value to breeding ducks will continue to do so into the future. The dynamic nature of climate in the Northern Great Plains and continued increases in air temperatures and precipitation variability...

Chelenzo Farms, located twenty miles south of the city of Santa Fe, New Mexico, is a regenerative farm that applies permaculture, soil health, and agroecology principles. It has three operating principles of research, education, and community. It practices dryland farming, focusing on the cultivation of agave and native plants. With over 200 varieties, agave can be distilled to make liquor, fermented for livestock feed, and made into textiles. In fact, 75% of those varieties have been cultivated in Mexico for thousands of years. Thus, agaves have long supported a variety of pollinators in the Southwest and along the border with Mexico in the Chihuahuan and Sonoran deserts, with the best known one being the...

In addition to these partnerships, PI-CASC has two important ongoing collaborative initiatives. Pacific Islands-Alaska CASC collaboration The PI-AK CASC collaboration is aimed at bringing together scientist and resource managers from the Pacific and Alaska regions to share insights on related climate adaptation challenges in Ridge-to-Reef (R2R) and Icefield-to-Ocean (I2O) ecosystems. Similarities in landscapes and communities in these...
Over the past four decades, annual area burned has increased significantly in California and across the western USA. This trend reflects a confluence of intersecting factors that affect wildfire regimes. It is correlated with increasing temperatures and atmospheric vapour pressure deficit. Anthropogenic climate change is the driver behind much of this change, in addition to influencing other climate-related factors, such as compression of the winter wet season. These climatic trends and associated increases in fire activity are projected to continue into the future. Additionally, factors related to the suppression of the Indigenous use of fire, aggressive fire suppression and, in some cases, changes in logging practices...
