General Principles of Freshwater and Estuary Ecology

ECOLOGYECOLOGY – how organisms interact with one another and with their environment

ENVIRONMENTENVIRONMENT – living and non-living components • ABIOTICABIOTIC – non-living component or physical factors – non-living component or physical factors

as soil, rainfall, sunlight, temperaturesas soil, rainfall, sunlight, temperatures• BIOTICBIOTIC – living component are other organisms – living component are other organisms.

ECOLOGICAL ORGANIZATION

• INDIVIDUALINDIVIDUAL – individual organisms• POPULATIONPOPULATION – organisms of same species in

same area (biotic factors)• COMMUNITYCOMMUNITY – several populations in same

area (biotic factors) • ECOSYSTEMECOSYSTEM – community plus abiotic factors • BIOSPHEREBIOSPHERE – all ecosystems on earth

Aquatic Ecosystems

Lotic ecosystems – flowing waterStreams Rivers

Lentic ecosystems – still waterPondsLakesWetlands

Estuary ecosystems

Watershed

A watershed or drainage basin is an area of land where water from rain and melting snow or ice drains downhill into a body of water, such as a river, lake, reservoir, estuary, wetland, sea or ocean.

ECOLOGY OF INDIVIDUALS

• Homeostasis Homeostasis – delicate balance– delicate balance • Components Components – Physiological Ecology Physiological Ecology – Temperature and Water BalanceTemperature and Water Balance– Light and Biological CyclesLight and Biological Cycles– Physiological Ecology and ConservationPhysiological Ecology and Conservation

ECOLOGY OF POPULATIONS

• Properties of populationsProperties of populations• Patterns of distribution and densityPatterns of distribution and density• Intraspecific competitionIntraspecific competition• Population dynamicsPopulation dynamics• Growth and regulationGrowth and regulation• Altering population growthAltering population growth• Human impactHuman impact

ECOLOGY OF COMMUNITIES

• Closed vs. Open communitiesClosed vs. Open communities– ClosedClosed – – sharp boundariessharp boundaries– OpenOpen – – Lack boundariesLack boundaries

• Species abundance and diversitySpecies abundance and diversity• Trophic Structure of CommunitiesTrophic Structure of Communities– Food chainsFood chains– Food webFood web– Trophic pyramidTrophic pyramid

Food Chain

• Producer• 1st order Consumer or Herbivore• 2nd order Consumer or 1st order Carnivore• 3rd order Consumer or 2nd order Carnivore• 4th order Consumer or 3rd order Carnivore• Decomposers – consume dead and decaying matter as

bacteria

Food Web

INTERACTIONS AMONG SPECIES

• InteractionsInteractions• Interspecific competitionInterspecific competition• PredationPredation• ExploitationExploitation• SymbiosisSymbiosis

Types of Species Interactions

• NeutralNeutral – two species do not interact – two species do not interact • Mutualism Mutualism – both benefit – both benefit • CommensalismCommensalism – one benefits, other neutral – one benefits, other neutral • ParasitismParasitism – one benefits, one harmed – one benefits, one harmed

but not killed but not killed • PredationPredation – one benefits, other killed – one benefits, other killed

ECOLOGY OF ECOSYSTEMS

• Energy Flow Energy Flow – Energy Flow PyramidsEnergy Flow Pyramids– Bio-mass PyramidsBio-mass Pyramids

• Community Succession and StabilityCommunity Succession and Stability• Nutrient Recycling Nutrient Recycling – – nutrient cycles nutrient cycles

Energy vs Nutrient

• Nutrients – cyclic(Biogeochemical Cycles)

• Energy flow – one way

Ecologic Pyramids

Ecological pyramid - a graph representing trophic level numbers within an ecosystem. The primary producer level is at the base of the pyramid with the consumer levels above. Numbers pyramid - compares the number of individuals in each trophic level. May be inverteddue to size of individualsBiomass pyramid - compares the total dry weight of the organisms in each trophic level. Energy pyramid - compares the total amount of energy available in each trophic level. This energy is usually measured in kilocalories.

Part 2: Macro-flora and Fauna

• Identify macroinvertebrates

• Identify aquatic nuisance plants by their common name

• Relate organisms to water and wetland quality

Indicator Species

FOR Division C ONLY students will also be expected to know the general ecology, life cycles, and feeding habitats of all listed organisms

Class 1-pollution sensitive Class 2-moderately sen. Class 3-moderately tolerant Class 4-pollution tol. Class 5 Air Br.

Aquatic Nuisance Plants: Purple Loosestrife, Eurasian Water Milfoil and Water Hyacinth.Aquatic Nuisance Animals: Zebra Mussel; Spiny Water Flea ,Asian Tiger Mosquito, and Carp

Part 3: Water Monitoring

• Understand and interpret data related to testing procedures and purposes for water testing (No actual testing)

• Build and demonstrate a salinometercapable of testing saltwater (1-10%)

Chemical Analysis • Salinity - Salinity - only actual testing with salinometeronly actual testing with salinometer• pHpH• PhosphatesPhosphates• Dissolved oxygenDissolved oxygen• TemperatureTemperature• NitratesNitrates• Fecal ColiformFecal Coliform• Total solidsTotal solids• Biochemical oxygen demand Biochemical oxygen demand

Salinomter – Hydrometer

• SalinometersSalinometers / HydrometersHydrometers

• HydrometerHydrometer calibrated to read in % of salt concentration

• MaterialsMaterials – soda straw modeling clay a fine-tipped permanent marker a tall clear container to hold the solution for calibrating your device salt for mixing one or more standard

solutions water (tap water will work-distilled is

better)

Sample Analysis Using the picture below, explain all of the possible human caused problems that can occur. In addition, what

types of chemical testing would you perform to confirm your suspicions?
