Biodiversity Seminar 1

Discipline:
Resource type:

This document serves as a teaching guide for the first of three seminars in a unit on biodiversity. This seminar focuses on global issues affecting biodiversity, including land and water use, greenhouse gases, decline of species, and emerging infectious diseases. The guide includes an overview, reading list, step-by-step seminar plan, and suggested discussion questions. The main seminar activity (an interrupted case study about bird populations in fragmented habitats) and assignment questions, which are described in the guide, are provided in related files.

Population Ecology

Discipline:
Resource type:

Expected decline without TEDS.

In this assignment, students will consider models for managing populations of sea turtles and fish. For the first question, students will apply their understanding of statistical concepts (means, standard deviations, t tests, hypothesis testing) to the results of a model simulation and use their analysis to make a policy recommendation about turtle conservation. In the second question, students will calculate and compare the survival rates resulting from two strategies of fish population management. This document serves as a student handout; an answer key is provided in an accompanying document.

Population Ecology

Discipline:
Resource type:

Population trajectory for species X in the Atlantic.

In this assignment, students will consider models for managing populations of sea turtles and fish. For the first question, students will apply their understanding of statistical concepts (means, standard deviations, t tests, hypothesis testing) to the results of a model simulation and use their analysis to make a policy recommendation about turtle conservation. In the second question, students will calculate and compare the survival rates resulting from two strategies of fish population management. This document serves as an answer key; a student handout is provided in an accompanying document.

Biodiversity of Pollinators

Discipline:

Median pollen deposition per visit.

In this class activity, students will analyze data from an investigation of the relationship between bee diversity and pollen deposition in farms and natural areas. Students will learn about the effects of biodiversity in a given ecosystem, and will apply their understanding of statistical concepts (mean, median, standard error). This document includes student handouts; an instructor guide is provided in an accompanying document.

Biodiversity of Pollinators

Discipline:

Cumulative estimated mean pollen deposition.

In this class activity, students will analyze data from an investigation of the relationship between bee diversity and pollen deposition in farms and natural areas. Students will learn about the effects of biodiversity in a given ecosystem, and will apply their understanding of statistical concepts (mean, median, standard error). This document serves as an instructor guide; student handouts are provided in accompanying documents.

The Birds and the Bees

Discipline:

Blue orchard bee.

In this handout, students are introduced to a study by Claire Kremen, Neal M. Williams, and Robbin W. Thorp that explores the role of biodiversity in crop pollination—an essential ecosystem service that is threatened by the decline of natural pollinator species. Students engage with these concepts in depth through the accompanying activity on pollination.
