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...

View Resource Impacts of Introduced Species: Interspecific Competition, Predation, and Other Species Interactions

Due to increasing global connectivity, global biotic interchange has been escalating, leading to species introductions in regions in which they are not indigenous. Most of these species do not establish and/or do not cause significant impacts, but a small proportion do and can have positive or, more often, negative ecological, economic, and cultural impacts. These species often interact with...

View Resource Issues in Ecology, Issue 05: Biotic Invasions

This report is an introduction to exotic species invasions. An exotic species becomes invasive, when it proliferates unchecked across the region in which it was introduced. The transformation from immigrant to invader and how humans act as dispersal agents is explained. Attributes of invaders, effects on native community, global ecological and economic consequences, prevention, and long term...

View Resource What are the Impacts of Introduced Species?

In this Issue, students will examine published data that address the ecological consequences of introduced species. Activities engage students in data analysis and hypothesis testing, and will increase their understanding of the complexities of ecological phenomena. This Issue focuses on ecological consequences of introduced species using several case studies - zebra mussels, brown tree snakes,...

View Resource Effects of multiple invasive species in experimental aquatic communities

In this exercise, students first work in small groups to collect background information on what mosquitofish and bullfrogs consume and then modify a food web based on that knowledge. Students then develop hypotheses of how these two invasive species may affect native amphibian species, snails, and zooplankton. Following, students work individually to analyze experimental mesocosm data to determine...
