INTRO TO AQUATIC ECOLOGY AND WATER CYCLE Flashcards
study of the planet’s oceanic and
freshwater environments
aquatic science
study of the biological, chemical, geological, optical and physical characteristics of oceans and
estuaries
Oceanography
study of these same characteristics in inland waters (lakes, rivers, streams, ponds, and wetlands).
Limnology
includes the study of relationships
between individuals of the same species, between different species, and between organisms and their physical and chemical environments in all aquatic environments, including oceans, estuaries, lakes, ponds, wetlands, rivers, and streams
Aquatic Ecology
these are the oceans, estuaries,
swamps, wetlands, streams, lakes,
rivers, springs, seeps, reservoirs,
ponds, groundwater, riparian areas,
and the fauna that reside within
them. Aquatic resources include
permanent, seasonal, flowing, standing, natural, or man-made water bodies
Aquatic Resources
Importance of Aquatic Ecosystem
- Biodiversity - Species richness/trophic structure
- Breeding - Breeding grounds for many species
- Buffer systems - Physical and chemical
- Sinks - Resting places for sediments and chemicals
- Only part of the hydrological cycle - What other parts are there?
refers to the management and
conservation of the aquatic resource, the concentration and capture of wild fish, as well as foraging for other aquatic resources such as crabs, prawns, snails, insects, aquatic plants, etc
Aquatic Resources Management
it never leaves the earth
water
constantly being cycled through the atmosphere, ocean, and land
water
It driven by energy from the sun and is crucial to the existence of life on our planet.
