Root nodules are a symbiotic relationship between a plant and nitrogen-fixing bacteria. A symbiotic relationship is one where both organisms benefit. Nitrogen-fixing bacteria change inorganic nitrogen from the air into ammonia, a form of nitrogen most organisms can use. They also use a process called rock dissolution to release other nutrients, such as calcium and...

Native species richness (of the 29 species) using cool to warm colors to represent overlapping distributions of few to many species, respectively. The top panel shows that the present (year 2000) distribution of hotspots in the national park aligns well with the distribution of SEAs. As shown in the lower panel, projected species richness at the end of the century (year...

Enhancing scientific research with reproducible, collaborative, and scalable data analysis workflows and methodologies.Example R code leveraging a reproducible data pipeline with the package “remake” to handle dependencies and organize workflow.
Mount Shasta, a steep-sided Cascade Range stratovolcano in Northern California, looms above Little Glass Mountain, a thick obsidian flow erupted from the Medicine Lake shield volcano about 1,000 years ago. These are just two of the young volcanic areas monitored by the USGS California Volcano Observatory. USGS photo.
Map showing the locations of all U.S. volcanoes with their threat category designated by color. Very high threat is red, high is orange, moderate is yellow, low is green, and very low is blue.
The alfalfa leafcutting bee (Megachile rotundata) is an introduced species common to Southwest Idaho. They originate from the old world, most likely from northeastern Africa or the Middle East. These bees are successful pollinators of various crops and have been imported to North America for use in agriculture and beekeeping.
Nor'Ida was a nor'easter that formed from the remnants of Hurricane Ida during November 2009. These beach profiles show the changes resulting from the storm which caused widespread beach erosion (loss of elevation) but little changes to the dunes. Hurricane Irene made landfall several times along the Atlantic coast of the U.S. in August 2011. By the time the storm was...
Two examples of pre- and post-Sandy beach profiles showing the flattening of dune and upper beach elevations in addition to morphological changes at the shoreface.
Coastal Change Hazards Portal showing probabilities of collision, overwash, and inundation at Fire Island during a Category 3 hurricane. For more information on other category storms, see https://marine.usgs.gov/coastalchangehazardsportal/).
The newest Fire Island coastal system research is focused on integrating information across research themes.
For more than 15 years, the USGS has actively studied natural and human changes to the shoreline, beaches, and dunes at Fire Island. This research program has refined our understanding of the long (decades to centuries)- and short-term (storm events, seasons, years) geomorphological changes on the barrier island that influence natural, cultural, and recreational resources...

Fire Island is a 50-km long barrier island along the south shore of Long Island, NY. The island is comprised of seventeen year-round communities; federal, state, and county parks; and supports distinct ecosystems alongside areas of economic and cultural value. In addition to providing resources to its residents, the barrier island also protects the heavily-populated...

In an effort spanning the Natural Hazards and Ecosystems Mission Areas, pilots from the Saint Petersburg and Woods Hole Coastal and Marine Science Centers collect imagery data using Unmanned Aerial System (UAS) while personnel from the Wetlands and Aquatic Research Center (WARC) conduct ground-based site surveys of Pelican Island, Alabama. These data are being combined to...
