These turtles are considered juveniles until they reach about 5 inches long. In this part of their range turtles remain juveniles and usually do not begin to reproduce until they are over ten years old.

Ammonia or ammonium? What’s the difference? In water, ammonia (NH3) and ammonium (NH4+) exist together in an equilibrium that depends on pH and temperature. As the temperature or pH rise, ammonia (NH3) becomes more abundant. This is important because ammonia is more toxic than ammonium.

This video presents the Spring 2025 Saline Lake Ecosystems Integrated Water Availability Assessment Spring Seminar by the U.S. Geological Survey (USGS). Hosted by Allison Shipp, the seminar provides updates on how hydroclimatic changes and water management affect terminal lake ecosystems and waterbird populations.

Welcome to another episode of Outstanding in the Field, the U.S. Geological Survey’s podcast series produced by the Ecosystems Mission Area. We highlight our fun and fascinating fieldwork studying ecosystems across the country. Today we’ll be discussing tiny communities that are found on the surface of the soil in the harsh environments of cold and hot deserts.

In this episode of Outstanding in the Field, we take you to the swamps and coastal wetlands of Louisiana, the land of bayous and beignets and a state with one of the most dynamic coastlines in the United States. The wetlands that make up the Louisiana coast are vast and help protect important cultural and natural resources.
