Interactions Theme Lecture

This set of flashcards covers key vocabulary and concepts from the Bio 100 Theme Lecture on ecological interactions.

Emergent properties (2)

• Product of interactions leading to new characteristics appearing in complex biological organization.

• Example: Cardiomyocytes vs Heart (Cell vs. Organ) These properties arise when components interact in a system, creating functions that are not present in individual parts.

Community, Comm Ecol & Emergent Props (Diversity, Species Composition, Species Interactions)

• A group of interacting species in a specific place and time.

• Community Ecology - studying plant-animal interactions

Nontrophic interactions (CMC - 3 Types)

No one is getting eaten. includes competition (inter-intra, symm-asymm), mutualism, and commensalism.

Trophic interactions

Interactions where one party consumes the other for energy, includes herbivory, predation, and parasitism.

Mutualism

A type of interaction where both parties benefit from each other.

Competition

An interaction where organisms require the same limited resource, can be interspecific or intraspecific. Asymmetric or symmetric.

Parasitism

A trophic interaction where one party consumes part of the prey while the prey's body serves as a habitat.

Keystone species (Direct vs. Indirect?)

INDIRECT Inc. biodiversity by consuming strongly interacting species (strongly interacting through herbivory, competition, disease, etc.)

Restoration ecology

The study of reversing habitat loss by restoring entire ecosystems.

Direct interactions

Interactions where species directly affect each other, such as competition or predation.

Indirect interactions

Interactions where one species indirectly affects others, typically through a keystone species.

Types of species interactions

Interactions can be classified as trophic or non-trophic, direct or indirect.

Plant-animal interactions

The study of how plants and animals interact, particularly in community ecology.

Ecosystem restoration

Efforts aimed at restoring the physical conditions and reintroducing native species to improve ecosystem health.

Nachusa Grasslands

A site where efforts to bring back bison are being studied as a means to restore ecological communities.
