Final Exam Flashcards
Domestic and feral cats: What is one of the primary ecological problems caused by domestic and feral cats?
one problem caused by domestic and feral cats is that they are the main killer of birds or mammals.
Domestic and feral cats: What is one key weakness in the group’s plan to curb this problem?
I think the group’s plan can be more concise in how people can help make a difference.
Spotted lanternflies: What is one of the primary problems caused by this species?
the species is liable for being toxic and promoting mold that is harmful to plants
Spotted lanternflies: What is one key weakness in the group’s plan to curb this problem?
I think the plan can rely less on volunteers and other organizations. People need to be educated on the topic before putting in efforts.
Asian carp: What is one of the primary problems caused by this species?
the species alters habitats while competing with other fishes for either food or habitats
Asian carp: What is one key weakness in the group’s plan to curb this problem?
the fish can not be relied as a food sources. luring over more fish will only promote to produce more of the carp fish even though they are invasive species
Agriculture lecture: describe what makes traditional shifting agriculture a sustainable form of agriculture.
-preserves soil fertility by the field
Agriculture lecture: how does a polyculture tend to lead to more efficient use of nutrients than a monoculture?
multiple crops species are in the same field and reduce risks
Agriculture lecture: describe how deep digging can lead to less need for weeding or herbicides
-decreases erosion, weeds, and increases yield per hectare
Agriculture lecture: describe in general terms where the nitrogen in green manure comes from
it comes from legume crops and it can be used as green fertilizer
Agriculture lecture: explain why field monitoring is such an important component of Integrated Pest Management (IPM)
it helps remove the possibility of having pesticides or the wrong type of pesticides
Landscaping: describe one of the steps that is part of implementing Integrated Pest Management (IPM) for ticks on residential properties
Monitor : ticks drags with cheese cloth. The ticks will get drag in the cloth and be demolished. This would minimize the use of herbicides and pesticides
Landscaping: what is meant by drip irrigation?
a technique system that requires less water by allowing water to drip into the roots of plants. This saves the amount of water
Landscaping: what is the risk for grass that is associated with watering lawns in the evening
excess water will still remain on the grass then this can cause diseases to grow
Landscaping: what are the two different major advantages of keeping grass height fairly high
-shades the soil
-provides more nutrients
Native Wildflower Meadows: State one specific detail about the steps that was mentioned in the lecture about establishing the native wildflower meadow
- remove turf:
- add compost:
- Rototill:
- Spread seeds
- Walk a lawn-roller over the site:
Water: define the term “ecological peak water”
the point where so much water is being redirected from the environment for human use
Water: why is it important to dilute the discharge of desalination plants before it is discharged out into the ocean?
its important because the plant may have pollutants that can cause damage to the marine population
Water: define the term “watershed”
an area of land that channels water into streams of water such as lakes or rivers
Water: define the term “Integrated Watershed Management”
the method of managing human led activities and the use of natural resources on water basis
Fisheries: how does eutrophication often lead to oxygen depletion?
dead algae decomposes and then oxygen is consumed. This results in low levels of oxygen in the water
Fisheries: what is meant by the term “fishing down the food web”?
declining of tropic level of fisheries and leads to a decrease in food chain
Fisheries: why does long-line fishing tend to lead to so much more “bycatch” than purse seine fishing
long line fishing: any fish can be caught
Seine fishing: large amounts of are netted and caught
Fisheries: what is meant by the term “maximum sustainable yield” (MSY), and state one major reason that makes it difficult to determine the MSY for fisheries
-the largest catch that is apart of the carrying capacity
-taking into account the fish deaths and fisheries growth
Fisheries: what is meant by Marine Protected Areas serving as “seed sources”?
-meaning to protect the breeding of fish areas while being able to allow repopulation those fish without causing depletion
Conservation Ecology: in which major biome does the available data suggest that habitat change is actually trending toward having less of an impact in recent times and into the near future than in the past
wetlands
Conservation Ecology: why did plant species richness decline so dramatically in 2004 in the treatment plots where the rainy season was experimentally extended
-increase in rainfall and soil got disturbed due to rainfall
Conservation Ecology: explain why wildlife populations with low genetic diversity are less likely to adapt to change than wildlife populations with high genetic diversity
-if species have low genetic diversity then they cannot evolve if the climate is altering
Conservation Ecology: what makes species that are dietary specialists so vulnerable to extinction
-this means that they have no alternative to foods which will increase their likelihood of becoming extinct
Conservation Ecology: what does the shape of the blue curve tell us about how money that is used for conservation science and conservation efforts tends to be spent
it shows that money is not being used in a useful manner in order to cover costs
Conservation Ecology at Ecosystem/Landscape Scales: describe an example that illustrates how an ecosystem service (of your choice) is not accounted for by market transactions in our economic system
Supporting ecosystem services: these are connected to habitat functionality. It includes primary production, soil formation, etc
This connects to the basis of our ecosystem while supporting ourselves.
Conservation Ecology at Ecosystem/Landscape Scales: what is one major conservation advantage to having habitat corridors that connect different wildlife reserves?
Wildlife crossings: habitat connectivity
Reserves habitats while making it safe
Conservation Ecology at Ecosystem/Landscape Scales: what is one potential conservation disadvantage to having habitat corridors that connect different wildlife reserves?
the difficulty of managing and protecting the habitat
Conservation Ecology at Ecosystem/Landscape Scales: give the most important reason that forests in our region tend to be much more resilient to long-term disturbances than forests in most of the Amazon basin of South America
the trees are more pure in terms of them growing naturally after being cut
Conservation Ecology at Ecosystem/Landscape Scales: explain the argument that the landfill could be an ecological trap for the birds that use it as a stopover site during migration
these birds are not receiving the right nutrients at landfills
Conservation Ecology at Ecosystem/Landscape Scales: explain why Professor W. suggested that the argument that you just described many not hold true
My argument is true because birds usually will stop at landfill if they see food waste, but it is not unusual for them not to
Questions about Stewardship: describe one of your technical details that you learned in this class that can be instrumental for more sustainable use of a natural resource
Stewardship about Water management: if we have better ways of a managing our water for natural resources then we can address the ecological problems in our world.
Questions about Stewardship: briefly address a common theme that came up on a multiple occasions in this course that is critical for the sustainable use of a variety of natural resources. (Include at least 2 different natural resources to illustrate your point)
Businesses and Regulations taking accountability for ensuring that our world is not overconsuming products. And having people educating on these current issues so they have a better understanding of how to be a healthy consumer. And if we preserve our resources then we can have a long lasting life.
