explain how this relates to both resiliency and biodiversity

Discuss the impacts of tropical rainforest deforestation in Sierra madre Rainforest. Propose a plan anchored in nature-based solutions to restore the basic ecosystem services.

The greatest SINGLE threat to most species of plants and animals is: Question 17 options: - chemical pollution of water and soil - buildup of toxic substances in food webs. - competition from invasive species over-harvesting for human consumption/use. - habitat destruction/alteration

t or f  If a pesticide was applied to gourds and started to bioaccumulate in them, biomagnification would result in high concentrations of the pesticide in wild dogs.    If a flood removed 50% of ants, then the biomass of pheasants would also decrease by 50%. Assume pheasants are not directly affected by flooding.   Ants and mice may be competing for tulips.

Capturing and relocating is stressful for animals.  In the zebra example, what are the stages of reintroduction, and what purpose does each step serve?   Why is the buffalo considered a success story for reintroduction?  (And -- based on what you know from lecture, what type of population growth pattern does this indicate?)   Park managers use the term “adaptive management”; what do you think this means, and what are two benefits of this approach to managing ecosystems?

What are the two key concepts for this section?What major ecological and economic benefits doforests provide? Describe the efforts of scientistsand economists to put a price tag on the majorecosystem services provided by forests and otherecosystems. Distinguish among old-growth(primary) forests, second-growth forests,and tree plantations (tree farms or commercialforests). Explain how increased reliance on treeplantations can reduce overall forest biodiversityand degrade forest topsoil.

What are three ways an ecologist might capture an animal?   one way an ecologist might sample a plant population in order to estimate numbers of plants?

Why have frequent small controlled-burn wildfires not helped to maintain chaparral ecosystems?   2 of 302 of 30 Questions                   Listen Question Why have frequent small controlled-burn wildfires not helped to maintain chaparral ecosystems?     Seeds of chaparral shrubs need a large accumulation of leaf litter in order to sprout.   The heat from forest fires destroys the roots of chaparral plants.   Fire destroys the seeds of many types of chaparral shrubs.   Burnt ground encourages the growth of grasses, which compete with shrubs for nutrients.

Consider aspects such as pharmaceuticals derived from plants, ecotourism, and the role of diverse ecosystems in supporting industries like agriculture and fishing. Include two examples where biodiversity loss has led to a loss of food, resources, or jobs.

In some marine habitats in New England, the population density of lobsters has been depleted due to heavy fishing. When this happens, it often follows that the diversity of species in the biological communities is reduced. Based on this observation, how would you characterize lobsters?     a keystone organism     a decomposer     a crustacean     a superior predator     a producer   The composition of a community refers to the     nutrients available in the soil.     type of succession that occurs locally.     sunlight available to drive the energy needed for metabolism.     extent vegetation covers the ground--a desert has low composition.     types of species adapted to living there.   Small fish sometimes swim very close to large predatory fishes such as sharks. There is no risk since the shark does not feed on these smaller fish. The small fish are able to eat the remains of prey such as seals that the shark rips apart when eating.…
