A Virtual Celebration of Science
What better way to celebrate the wonders of STEAM (Science, Technology, Engineering, Art, and Math) than hosting a virtual Science Festival?
Why the Ocean?
USGS scientists share brief thoughts about why they have focused their careers on studying our oceans and coasts. Here’s why they study the ocean:

Stress gradients interact with disturbance to reveal alternative states in salt marsh: Multivariate resilience at the landscape scale
Stress gradients influence many ecosystem processes and properties, including ecosystem recovery from and resistance to disturbance. While recent analytical approaches have advanced multivariate metrics of ecosystem resilience that allow quantification of conceptual resilience models and identification of thresholds of state change, these...
Jones, Scott; Stagg, Camille; Yando, Erik S.; James, W. Ryan; Buffington, Kevin J.; Hester, Mark W. Germination potential of baldcypress (Taxodium distichum) swamp soil seed bank along geographical gradients
Changing environments of temperature, precipitation and moisture availability can affect vegetation in ecosystems, by affecting regeneration from the seed bank. Our objective was to explore the responses of soil seed bank germination to climate-related environments along geographic gradients. We collected seed banks in baldcypress (Taxodium...
Lei, Ting; Middleton, Beth Carrying capacity of spatially distributed metapopulations
Carrying capacity is a key concept in ecology. A body of theory, based on the logistic equation, has extended predictions of carrying capacity to spatially distributed, dispersing populations. However, this theory has only recently been tested empirically. The experimental results disagree with some theoretical predictions of when they are...
