Vocabulary
Those that normally live and thrive in a particular community
Native species
This species were accidentally introduced to North America, and are now found in some Pennsylvanian waterways
Zebra mussels (Dreissena polymorpha),
Impact of invasive species
displaces native herbaceous plants, reducing biodiversity, and reducing food available for wildlife species, Reduce forest health and productivity, Some invasive species kill native species, Economic impacts
True or False: Invasive species are harmful to the environment
True
True or False: A cricket's chirp can tell you the temperature, as the speed of its chirps is directly related to the ambient temperature
True
A species living outside its native distributional range
non-native species
This species was introduced for use as an ornamental plant, to control erosion, and to use as “living” fences for livestock
Multiflora rose (Rosa multiflora)
What makes Japanese stilt grass a successful invader?
• It can become established and live in a wide variety of habitats. • Each plant produces hundreds of seeds that can remain viable in the seed bank for upward of five years. • Seed can be transported long distances by water or contaminated hay, seed mix and soil. • Plants also reproduce asexually. They form roots at the nodes, which allows for new vegetative stem growth. • People can spread stilt grass by carrying the seeds on their shoes, equipment and vehicles.
Ways that invasive species are introduced to their new environment
primarily by human activities, including transporting them in the ballast water of ships, as hitchhikers on goods like shipping pallets and firewood, on personal equipment like boats and gear, or through the intentional release of unwanted pets or plants
True or False: Mrs. Davison can understand 5 languages; Norwegian, Swedish, Finnish, German, and English
False; Not Finnish, but Danish
what adversely affects habitats and biodiversity
A non-native species
This species has killed millions of ash trees in the mid-west and has recently been found in Pennsylvania
Emerald ash borer (Agrilus planipennis),
What makes garlic mustard a successful invader?
• It can germinate in shade. • Is capable of ballistic seed dispersal of up to 10 feet. • Its seeds lie dormant for up to 6 years. • Its seed spread by animals and water. • It forms spreading monocultures. • It is allelopathic, meaning it produces chemicals that inhibit the growth of other plants
This happens when species are established
Spreading and reproducing
How many hearts does an octopus have?
Octopuses have three hearts; one pumps blood to the body, while the other two pump it to the gills.
the specific natural environment or place where a particular plant, animal, or other organism lives, thriving by finding the food, shelter, water, and mates it needs for survival and reproduction
Habitat
This species becomes established on recently disturbed areas and outcompetes native plants, reducing biodiversity.
Japanese stilt grass (Microstegium vimineum),
Name 5 traits common to invasive plant species
• Self-compatible • Flowers early • Produces abundant seeds • Disperses seeds widely • Grows rapidly • Spreads asexually • Strong competitors
Invasive species does this to the ecosystem
disrupts the ecosystem
This is how many years Mrs. Davison has been teaching
11 years
an organism's role and position within a community, encompassing the physical and environmental conditions it needs to survive, such as temperature or terrain, and its interactions with other species, like predators and prey
Niche
its ability to tolerate a wide-range of environments, and high reproduction rate; females release up to 100,000 eggs per year
Zebra mussels
Name 3 Common characteristics of invasive species
• Have few natural predators, competitors, parasites or diseases • Have high reproductive rates • Are long-lived • Are generalists • Are pioneer species
Name 3 bodies of water invasive species can be found in
Ocean, lakes, rivers, wetlands
