This interdisciplinary pedagogical case study focuses on differences between rural and urban coyotes at the levels of organismal and community ecology, including how their gut microbiomes could affect their behaviour. The health and fitness of rural and urban coyote populations vary dramatically with the latter being poor as a result of their consumption of carbohydrate-rich anthropogenic food, compared to a more natural protein-rich diet. This difference is associated with altered gut microbiome composition. The case explores how altered microbiomes can influence behavior changes through the gut-brain axis. Cross talk between the brain and gut microbiome involves multiple physiological systems including the immune, endocrine, and nervous systems. This case showcases the interdisciplinary nature of science by having students explore the connection between these macro and micro-level systems. It is based on a manuscript by Sugden et al. (2020) supporting the existence of distinct gut microbiomes in rural and urban coyotes. Interdisciplinary connection - Immunology+Microbiology+Ecology+Animal Behavior

Description

The case features an engaging narrative between two graduate students in animal behaviour and immunology programs, unexpectedly helping each other gain insight into the complexities of each other's fields. The case was designed with face-to-face modality in mind, but could also easily be implemented in synchronous or asynchronous online courses (Bixler et al., 2021). 

Intended audience:

The case is designed for introductory life science undergraduate students but can be adapted for more advanced and focused courses (e.g., animal behavior, immunology, microbiology, neurobiology).

Overarching goal:

The overarching learning goal for this case is for students to explore the interdisciplinary nature of science, while making connections with ecological concepts with cell and molecular concepts. By the end of this case, students should be able to make connections between life science subdisciplines that span immunology, microbiology, ecology, and animal behavior. The activity is intended for use with introductory biology, general biology, or non-major biology courses. As such, the activity is used to teach fundamental biology concepts and core competencies, as listed in the Vision and Change report (AAAS, 2011), and those described in the recommended guidelines developed by the Undergraduate Immunology Education Task Force. The core concepts and the learning outcomes for this activity are noted below:

1. Core Concept: Systems

a) Identify environmental factors (abiotic and biotic) that affect the distribution of species.

b) Identify various types of interactions among coyotes and other species. 

c) Outline the gut-brain axis and describe how it integrates multiple physiological processes. 

d) Describe how the the gut-brain axis can be influenced by environmental factors. 

e) Construct a conceptual model for how coyote ecological context (urban vs. rural) can lead to changes in animal behaviour and health.

2) Core Competency: Ability to tap into the interdisciplinary nature of science.
