Stream Ecology Presentations

A series of PowerPoint presentations were developed for the Water for Everyone project. Three of these are provided here for you to review for your own knowledge. The presentations can also be used as part of a more in-depth stream ecology learning day. In the Planning a Stream Ecology training section of this website, we have provided guidance and materials including sample agendas, facilitator notes, participant handouts, and details about using the presentations to help you host a local stream ecology workshop.

Integrating Principles and Concepts from General Ecology, Stream Biology, Biological Diversity of Stream Invertebrates, and Water Chemistry

This 45-slide presentation provides an overview of stream ecology.  Ecology is the study of organisms and how they interact with their environment.  Basic ecological concepts are introduced as they are related to stream ecosystems.  For instance, food chains and food webs of stream ecosystems are explained, as are effects on these by such things as seasonal influence, stream order, and scale.  Thought questions are posed to help the viewer think through the concepts that have been introduced.  No previous knowledge of stream ecology is expected of the viewer.

 

Natural History of Stream Invertebrates: Using and Making Sense of Biotic Indices, and Beyond

This 38-slide presentation is designed to provide viewers an overview of behaviors and adaptations some aquatic macroinvertebrates have for living successfully in the water and within microhabitats within streams.  Feeding group types (e.g., grazers, shredders) and basic scientific classification principles are explained within the presentation.  Examples are provided to demonstrate how diverse families (e.g., types of dragonflies) are within ten orders (e.g., dragonflies, mayflies, stoneflies, etc.) of aquatic macroinvertebrates.  Viewers are introduced to biotic indices and their use in rating water quality in stream ecosystems.

Relationships Between Habitat Preferences, Feeding, Life Cycles of Aquatic Insects & Stream Health

Aquatic insects inhabit virtually every possible freshwater habitat.  This 35-slide presentation explores some of the factors of the behavior, morphology, habitat choices, and evolutionary history of mayflies and caddisflies that have allowed these two groups of insects to be so successful at living in freshwater environments.
