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 Testing hypotheses about behavioral interactions between cats, coyotes, and birds at carcasses

In this activity, students will play the role of a field biologist quantifying and explaining animal behavior using the scientific method (observation – hypothesis – prediction – test). Powerpoint slides contain a series of photos of scavengers at deer carcasses. Students will form hypotheses about the behavioral interactions in the photos, then make predictions that could be used to test their...

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 Quantifying the impact of a brood parasite on crows

This class was designed for an introductory ecology course. Students are introduced to Microsoft Excel PivotTables by amending an existing PivotTable, then create their own PivotTables to explore the main data sets. These data sets provide information on the breeding success of carrion crows parasitized by great spotted cuckoos in Spain. Students summarise the large data sets, produce bar charts,...

View Resource Case Study on Mark and Recapture

Estimating the population size of animals is an important task for wildlife biologists, who can use the data to assess the health of a population. It requires diligent observation skills coupled with the ability to use empirical models that effectively determine the number of animals based on field surveys. The most common method for estimating the population size of animals is mark and recapture....
