Lecture 5 - Boring Ecology

Front 1

Factors that limit species distributions in terrestrial environments:

Back 1

Precipitation and the rain shadow

Front 2

_________ ecology is concerned with the behavioral, physiological, and morphological ways individuals interact with the environment.

Back 2

Organismal ecology is concerned with the behavioral, physiological, and morphological ways individuals interact with the environment.

Front 3

A ________ is a group of individuals of the same species living in a particular geographic area.

Back 3

A population is a group of individuals of the same species living in a particular geographic area.

Front 4

___________ ecology examines factors that affect population size and composition.

Back 4

Population ecology examines factors that affect population size and composition.

Front 5

A __________ consists of all the organisms of all the species that inhabit a particular area.

Back 5

A community consists of all the organisms of all the species that inhabit a particular area. Community ecology examines the interactions between species and considers how factors such as predation, competition, disease, and disturbance affect community structure and organization.

Front 6

______________ ecology examines the interactions between species and considers how factors such as predation, competition, disease, and disturbance affect community structure and organization.

Back 6

Community ecology examines the interactions between species and considers how factors such as predation, competition, disease, and disturbance affect community structure and organization.

Front 7

An ecosystem consists of all the __________ factors in addition to the entire community of species that exist in a certain area. Ecosystem ecology studies energy flow and cycling of chemicals among the various abiotic and biotic components.

Back 7

An ecosystem consists of all the abiotic factors in addition to the entire community of species that exist in a certain area. Ecosystem ecology studies energy flow and cycling of chemicals among the various abiotic and biotic components.

Front 8

Ecology is the scientific study of the interactions between organisms and their environment. True or False??

Back 8

TRUE!!

Front 9

___________ is the scientific study of the interactions between organisms and their environment.

Back 9

Ecology is the scientific study of the interactions between organisms and their environment.

Front 10

What is Ecology?

Back 10

Ecology is the scientific study of the interactions between organisms and their environment.

Front 11

The biosphere is the global ecosystem, the sum of all of the planet’s ecosystems. True or False?

Back 11

TRUE

Front 12

_________ factors affect the distribution of organisms.

Back 12

Biotic factors affect the distribution of organisms. Or, Abiotic!

Front 13

Four abiotic factors are major components of climate, what are they?

Back 13

Temperature
Water
Sunlight
Wind

Front 14

Abiotic factors affect the distribution of organisms. True or False?

Back 14

True - both Abiotic and BIOTIC Factors affect distribution of organisms!!

Front 15

Climatic factors, especially temperature and water, have a major influence on the distribution of organisms. True or False?

Back 15

TRUE!

Front 16

Niche – The range of conditions a species cannot tolerate? True or False ?

Back 16

False!! Niche - range of conditions species can tolerate

Front 17

Aquatic biomes occupy the smallest part of the biosphere. True or False?

Back 17

FALSE! Aquatic biomes occupy the LARGEST part (biosphere)

Front 18

_____________ Niche: The fundamental niche is the potential niche, in other words the niche that would prevail in the absence of competition and other factors that might constrain its acquisition and use of the resources.

Back 18

Fundamental Niche: The fundamental niche is the potential niche, in other words the niche that would prevail in the absence of competition and other factors that might constrain its acquisition and use of the resources.

Front 19

_______ Niche: The actual niche an organism occupies as a result of competition for its resources, problems in acquiring those resources. Always smaller than other niche!

Back 19

Realized Niche: The actual niche an organism occupies as a result of competition for its resources, problems in acquiring those resources. The realized niche is always smaller than the fundamental niche!

Front 20

Eutrophic lakes are deep, nutrient poor, oxygen rich, and contain little life. True or False?

Back 20

FALSE!! -- Oligotrophic lakes are deep, nutrient poor, oxygen rich, and contain little life.

Front 21

Eutrophic lakes are shallow, nutrient rich, and oxygen poor. True or False?

Back 21

TRUE

Front 22

Factors that limit species distributions in aquatic environments are?

Back 22

-Salinity
-Light Penetration
-Temperature

Front 23

Distinguish between Lotic vs. Lentic

Back 23

Lotic: moving water like streams and Lentic: standing water like lakes!

Front 24

Streams vary from headwaters to the river mouth: The River Continuum Concept
Headwaters are dominated by Allocthonous inputs (like leaves from trees)
a. insects include shredders and collectors
b. fish include species that are adapted to cool, oxygenated water

Back 24

Just Read It

Front 25

Large rivers are dominated by Autochthonous inputs from primary producers

Back 25

Just Read it

Front 26

In lotic habitats, some fish species are adapted to capture prey moving past them in the current, faster currents bring more food but require more energy expenditure to maintain position True or False?

Back 26

TRUE

Front 27

In lentic habitats, some fish species have external taste buds on specialized structures that allow them to sense food in turbid environments? True or False?

Back 27

TRUE

Front 28

The limnetic zone is the open water, and varies with depth: Name new zones (layers) of the lake:

Back 28

Hypolimnon - deeper cooler part of lake
Epilimnion (upper layer) light penetrates/ warms H20

Front 29

Streams and rivers are bodies of water moving continuously in one direction. As water travels downstream, it picks up __ and ________ on the way.

Back 29

Picks up O2 and nutrients on the way!

Front 30

Many streams and rivers have been polluted by humans, degrading water quality and killing aquatic organisms. How?

Back 30

Damming/Flood Control impairs natural functioning of streams; also threatens migration species (salmon)
