View Resource Hatchling loggerhead sea turtle (Caretta caretta) on a beach in South Carolina

Photo of a hatchling loggerhead sea turtle (Caretta caretta) on a beach in South Carolina. Female loggerheads lay their eggs on land and juveniles, such as the one pictured here, migrate from the beach into the ocean. Unlike their adult counterparts that have red shells, juvenile sea turtles have dark-brown shells. This hatchling measured 5 cm (2 inches) long, which is average for the species.

First, adult females tend to avoid laying their eggs on beaches with artificial light. Second, hatchlings become disoriented and fail to migrate toward the ocean and instead wander along the beach and even further inlands. While wandering, disoriented...

View Resource Visualizing a Disease Outbreak Using ESRI Story Maps

At the end of this activity, students will demonstrate their ability to understand basic principles of disease transmission, convey real epidemiological data as visual stories, and develop a plan to handle a “real” outbreak. Instructors may evaluate students’ knowledge and comprehension of the basic principles of disease transmission by analyzing how students’ initial and final hypotheses changed...

View Resource Size, Niches, and the Latitudinal Diversity Gradient

Species diversity generally increases in the tropics but testing theories that explain this phenomenon is challenging. Here we use body size to quantify niches in ecological communities and explore how species diversify towards the equator.

View Resource To Plant, or Not to Plant? Regulating Invasive Plant Species in the Mid-Atlantic States: A Social-Ecological System Case Study

As invasive plant species spread across landscapes, costs of their economic and environmental impacts have sparked interest in regulating their sale and transport. Laws now prohibit the sale and movement of some species. State and local governments are drafting regulations that will affect horticulture, plant nurseries, and options for landscape design. Awareness of invasive plant species is...
