Snake fungal disease (SFD) is an emerging disease that has devastated some native snake populations in the eastern U.S. The disease can cause crusty scales, cloudy eyes, abnormal molting and other symptoms, and it can be fatal. Scientists think all snake species could be susceptible to it, but a new USGS field study found little evidence of the disease in South Florida’s invasive Burmese pythons. SFD is thought to be spread through direct contact with an infected snake or an environment contaminated by the fungus. If invasive pythons were infected with SFD, they might spread the disease to native snake species throughout South Florida, especially in ecologically vulnerable areas like the Everglades.
USGS scientists tested Burmese pythons and native snakes in southwest Florida for the fungus that causes SFD. Three of 26 native snakes tested positive – a sign that the fungus is in the environment. One of 45 pythons tested positive, a juvenile snake that had a minimal amount of the fungus on its skin and no physical signs of SFD. It’s possible that the pythons rarely carry the fungus or may also have such small amounts of it on their skin that it isn’t readily detected. The scientists called for further studies to find out why these pythons showed so few traces of SFD.

Elevation-derived hydrography: In support of improvements to the National Hydrography Dataset and the addition of elevation data from the 3D Elevation Program, the USGS releases new guidance for creating elevation-derived hydrographic features that are appropriate for inclusion into the NHD.
Deriving NHD features from 3DEP data greatly enhances the vertical and horizontal spatial integration between the terrain and the stream network and provides the level of accuracy and detail required for local-scale water resources management applications while also supporting broader-scale hydrologic modeling.: http://ow.ly/VNa250Az4AF

Today, the USGS, National Park Service, U.S. Fish and Wildlife Service and Conservancy of Southwest Florida announced they have teamed up to radio-track Burmese pythons in Big Cypress National Preserve, Crocodile Lake National Wildlife Refuge and other areas of Southwest Florida.

This new effort marks the first-time pythons are being tracked in so many different habitats to better understand python biology across the region and ultimately find ways to more effectively control this invasive species.

“Our experts are committed to using innovative methods and technologies to track invasive pythons,” said U.S. Secretary of the Interior David L. Bernhardt. “This partnership will further aid in our efforts to eliminate this growing threat to South Florida’s ecosystem and biodiversity.”

Positive news for ʻōhiʻa restoration in Hawaiʻi! A new study published recently in Restoration Ecology indicates that ʻōhiʻa seedlings planted into sites with active Rapid ʻŌhiʻa Death (ROD) infections can survive for at least 1 year. ROD is a newly emerging disease caused by fungal pathogens. Since the disease was first discovered, ROD has killed at least 1 million ʻōhiʻa - a tree that is foundational to the Hawaiian landscape and culture. Its loss is detrimental to habitat for endangered birds and plants, ecosystem processes, and the cultural heritage of Hawaiians. This study indicates that seedlings can survive exposure to the disease, even when it is found in the local area, and in the soil. Longer-term studies are being carried out to find out how long the ʻōhiʻa seedlings will survive in ROD affected areas. There remains no treatment for infected trees, so slowing the spread of ROD remains important to protect native Hawaiian forests. Learn more: http://ow.ly/OUpL50Atjma

Mercury is a pollutant that accumulates within the animals that ingest it and becomes more concentrated as it travels up the food chain. Mercury occurs in food webs throughout the world, even in seemingly remote locations. A prime example is the relatively isolated Grand Canyon National Park where animals living in and next to the Colorado River can be exposed to mercury.

A new study describes how food web dynamics influence the movement of mercury throughout the Colorado River in the Grand Canyon. The study looked at mercury movement during normal flows and throughout a high-flow event.

“Understanding the factors that control the movement of mercury through food webs can help resource managers protect ecosystems that are susceptible to mercury pollution,” said David Walters, USGS scientist and lead author of the study.

This study was done in cooperation with the Cary Institute of Ecosystem Studies, the National Park Service, Montana State University, Idaho State University and the FLBS - Flathead Lake Biological Station, The University of Montana.

New ‘US Topo’ Maps for Alaska’s Tongass and Chugach National Forests Available: The USGS National Geospatial Program, in cooperation with the USDA Forest Service, the State of Alaska and other partners, the National Geospatial Program has generated and published new 1:25,000-scale digital maps for Chugach and Tongass National Forests in Alaska.
These new digital 'US Topo' maps replace decades-old 1:63,360-scale USGS maps. These updated and enhanced maps display the landscape in much greater detail than the earlier maps. New elevation data acquired prior to map production is used to create enhanced contours and shaded relief backdrops for the maps. A satellite image from the State of Alaska is used as a separate backdrop scene on the map. The Forest Service provided updated data depicting roads, trails, campgrounds and other features of interest.
Alaska US Topo maps are available for free download in a convenient PDF format at http://ow.ly/O6be50Asj3L, and can be viewed on a computer or mobile device or printed to paper.
Paper copies can purchased from the USGS store located online at http://ow.ly/ZXIy50Asj3K.

The USGS is celebrating the 100-year anniversary of their Bird Banding Laboratory and a century of advancing avian conservation science. The lab provides critical science to land- and resource managers responsible for conserving and managing bird species in North America.

Scientists can keep track of individual birds by placing aluminum and/or colored bands on a bird’s legs. Each set of bands has a unique combination of colors and numbers. Every time a scientist bands a bird, he or she records the location and date as well as the bird’s species, gender, estimated age and other features, and sends that information to the lab.

This information helps track birds’ behavior, migration, lifespans, populations, diseases and levels of environmental contaminants. The archived data help experts make important management and conservation decisions, which is especially important to ensure healthy game bird populations as well as the protection and recovery of endangered and threatened birds.

Laboratory staffers manage more than 77 million archived banding records and more than 5 million bird encounter reports, with an average of nearly 1.2 million banding records and 100,000 encounter reports submitted each year.

The National Map Corps is a recognized citizen science program that leverages crowd sourcing techniques and volunteers to update structure data on USGS map products. To reward, recognize and motivate these participants, the program awards “virtual badges” as they increase their number of submitted “points”.
This week, we highlight the Squadron of Biplane Spectators badge. This virtual award is earned with the submission of more than 6,000 points and is the top badge that TNMCorps currently awards. A small group of volunteers have surpassed this award level and we truly appreciate their time, dedication and contributions. Also, the Program is developing new awards for those intrepid citizen scientist who have reached even higher point totals. .
So what is the background behind the advent of airplanes and mapping? World War I saw the first use and rapid development of airplane-based photographic reconnaissance. Proving to be more agile and reliable than balloons, pigeons, or rockets. Both sides of the conflict used aerial photographs to monitor the expansion of trenches and troop movements. From these activities during war time evolved the science of photogrammetry.
This completes the weekly posts of TNMCorps virtual awards, for now. We will announce new awards in the near future.

Do you have what it takes to be a bat biologist?

USGS bat researchers are counting Townsend’s big-eared bats to see how their populations are doing. Watch the video and try your hand at counting bats to see how your skills compare to a professional.

By the way, you don’t need the sound on to count the bats, but if you turn it on you will be able to hear the bats’ echolocation calls while you count! The calls, which sound like clicks, were picked up by an ultrasonic microphone near the roost.

Remembering Ridgecrest

Earthquakes can be unsettling.

Feeling the ground beneath you shake and seeing the environment around you roll and rock can leave one feeling wary of what is to come next. This was certainly the case for the community of Ridgecrest, California, on July 4th, 2019, as they experienced a magnitude 6.4 earthquake. As scientists and responders from different agencies and organizations focused their energy on emergency response, another stronger earthquake shook the area about 33 hours later.

In the video, “Remembering Ridgecrest,” USGS scientists recollect how they responded on July 4, 2019, and their most memorable moments during the immediate and subsequent response. This video is only a small snapshot of the many USGS employees who responded, and only begins to allude to the myriad of partner agencies and institutions who were involved. This kind of research and partnership ultimately can help save lives and property.
