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 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 Catching ANOVA through mosquitoes

This activity is designed to show students how to perform an ANOVA using RStudio. To integrate the lesson plan with course content in an undergraduate ecology lecture course, students read an accessible scientific article (Chase & Knight 2003) that explores interaction between abiotic (climate and habitat permanence) and biotic (competition & predation) environmental conditions on the population...

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...
