Intro to Natural Resources
What are materials or substances which are found in nature and can be used for economic gains, such as minerals, forests, water and fertile land. Some are finite, whereas others can be replenished or grown, but all types should be managed carefully.
What is a natural resource?
Define ichthyology?
What is the study of fish.
The permeant loss of a species.
What is extinction?
ODNR stands for?
What is the Ohio Department of Natural Resources.
An introduced, nonnative organism (disease, parasite, plant, or animal) that begins to spread or expand its range from the site of its original introduction and that has the potential to cause harm to the environment, the economy, or to human health.
What is an invasive species?
Name the 3 most important natural resources?
What is air, water, and soil.
Nonmammalian vertebrate. Known for swimming and being made into sushi.
What is a fish?
Name 3 mammalian species in Ohio that went extinct after European settlement (may include re-established populations).
What is the beaver, elk, bison, mountain lion, bobcat, grey wolf, WT deer, black bear, river otters.
The ODNR division Levi and I work for?
What is DNAP or the Division of Natural Areas and Preserves.
Type of habitat can invasive species be found in?
What is any habitat in the world!
Resources that can last forever regardless of human activities. (i.e. Solar, wind, geothermal, water, soil, air, ocean waves, and tides are examples of such resources)
What is a resource that is not exhaustible?
This fin is located along the back of most fish.
What is the dorsal fin?
A type of biodiversity that refers to the number of different species that live in an environment as well as the number of different species that live on Earth.
What is species biodiversity?
The study of interactions between organisms and the environment?
What is ecology.
Name 5 invasive plants in Ohio.
What is purple loosestrife, garlic mustard, shrub honeysuckles, Asiatic bittersweet, reed canary grass, Japanese stilt grass, multiflora rose, autumn olive, privet, Japanese barberry, Tree of heaven, Empress tree, buckthorns, thistle, teasel, Japanese Spirea, hairy joint grass, etc.
Name 3 threats to natural resources.
What is Habitat destruction, pollution, deforestation, introduced species, overexploitation, environmental degradation, overfishing/ overharvesting, invasive species, habitat fragmentation, wildlife trade, pollution, extinction
The #1 invasive fish in Ohio?
What is Asian Carp. (i.e. Bighead Carp, Silver Carp, Black Carp, Grass Carp.
Trophic levels provide a structure for understanding food chains and how energy flows through an ecosystem. At the base of the pyramid are the autotrophs/producers, who use photosynthesis or chemosynthesis to make their own food. Primary consumers/heterotrophs, make up the second level. Secondary/tertiary consumers, follow in the subsequent sections of the pyramid. At each step up the food chain, only 10 percent of the energy is passed on to the next level, while approximately 90 percent of the energy is lost as heat.
What is energy flow?
To preserve Ohio’s unique natural heritage by protecting and restoring our finest land and water resources for future generations.
What is DNAP Mission Statement.
How do invasive plant species spread into Ohio?
What is all of these species have come across because of humans. Most have come from Europe, some have come from Asia. There are a few from other places in the world, but almost all are from European or Asian origin. Many of them were brought up on purpose, intentionally, so either to use as food, or to use as ornamental species in gardens. And, then, some came over with humans accidentally. So things came across in soil ship ballast, especially wetland species like phragmites and purple loosetrife.
This is the maximum population size of a biological species that can be sustained by that specific environment, given the food, habitat, water, and other resources available.
What is carrying capacity of an environment?
This salmonid is native to Ohio, but its habitat is threatened by mining, culverts, species introductions, and urbanization (just to name a few)
What are brook trout
Why biodiversity matters?
Diversity = Resilience. Biodiversity is essential for the processes that support all life on Earth, including humans. Without a wide range of animals, plants and microorganisms, we cannot have the healthy ecosystems that we rely on to provide us with the air we breathe and the food we eat.
Name 3 things the Division of Natural Areas and Preserves does.
What is trail maintenance, posting and boundary checks, invasive species control, volunteer engagement, interpretive programing, preserve plants, animals, geological features and entire ecosystems!
Capable of causing extinctions of native plants and animals, reducing biodiversity, competing with native organisms for limited resources, and altering habitats. This can result in huge economic impacts and fundamental disruptions of ecosystems.
What is how invasive species affect biodiversity?
