In a tropical rainforest, an open gap lacking vegetation has been created by the fall of a large tree. Which of the following statements describes the characteristics of the plant species that are last to colonize this disturbed habitat?
a.
they have low reproductive rates and are good competitors
b.
they are good colonizers
c.
they have high reproductive rates and are poor competitors
d.
they are dominated by r-selected species
e.
they have high species diversity
Invasive species often display a wave of advance as they
colonize new areas. Mathematical models based on random
dispersal and reproduction have demonstrated that the speed
with which such waves move is given by the expression
2Dr, where r is the reproductive rate of individuals and D
is a parameter quantifying dispersal. Calculate the derivative
of the wave speed with respect to the reproductive rate r and
explain its meaning.
Using the community assembly theory, provide a framework or explanation on: How do some exotic species outperform locally-adapted native species? Cite specific example(s).

- Environments with low frequency and intensity of disturbance tend to have ________ species diversity because ______. Group of answer choices A) low; the best competitors exclude any other species B) high; disturbances kill off a large number of individuals C) low; there are fewer late-successional species than early-successional species D) high; more species can colonize over a longer period of time Question: Answer choice selection is either: Burkina Faso or Italy for all three answer choicesarrow_forwarddetermine how to deal with the invasive species that are listed here, or determine if a species is actually beneficial to the community they've been introduced to. the honeybee is naturally from europe, and was introduced to north america in the 1700s. in the modern united states honeybees are major pollinators. this species hasn't outcompeted other north american species like the bumblebee. do you choose to try to control this species, or not?the africanized honeybee better known as the "killer bee" escaped a facility in brazil. the killer bee's population has exploded, but this subspecies has not directly impacted other bee species. the well known aggressiveness of the hives has caused consistent problems over the past few decades for humans in several conditions. do you choose to try to control this species, or not? burmese python.jpg the burmese python can grow to be large constrictor capable of reaching 23 ft. in some cases. these snakes were illegally kept as pets, and released…arrow_forwardThe accelerating spread of non-native species is a major component of anthropogenic global change, what characteristics of non-native species facilitate their ability to become established in novel environments and become invasive?arrow_forward
- for species invasion what are the mechanism(s) by which invasive species overcome these barriers to immigration that exist in stable ecosystemsarrow_forwardConsider an ecological network consisting of three interconnected habitats (A BCA). Ecologists want to model the occupancy dynamics of a particular species "Species" across these habitats over time using a discrete time discrete state stochastic process. State Space: State 0: Species X is absent from all habitats. State 1: Species X is present in Habitat A State 2 : Species X is present in Habitat B. State 3: Species X is present in Habitat C. State 4: Species X is present in Habitats A&B State 5: Species X is present in Habitats A&C. State 6: Species X is present in Habitats B&C. State 7: Species X is present in All Habitats. Transition Probabilities: Rule 1: The probability of colonizing an adjacent habitat is 0.2. Rule 2: The probability of extinction from a habitat is 0.15. Rule 3: The probability of recolonization of a random habitat is 0.1 A) Draw a schematic diagram of the Markov Process illustrating states and transitions.

- When it comes to species invasions what are the barriers to immigration that exist in stable ecosystemsarrow_forwardChanging conditions put intense pressure on organisms-some of which become extinct. For example, of the original 62 species of honeycreeper found in Hawaii only 18 remain. Scientists have the technologies that may allow bringing back organisms that have become extinct. This brings up ethical questions about the cost/benefit of resurrecting extinct species and whether it is the right thing to do. Joseph Bennett, a professor of biology at Carleton University in Ontario, wanted to determine the cost of resurrecting and maintaining an extinct species. Since the up-front cost of resurrecting an extinct species is very difficult to determine, the researchers decided instead to look at the cost of reintroducing and protecting a resurrected organism in the wild. To accomplish this, the researchers considered 70 animals from New Zealand and 29 animals from New South Wales that went extinct within the last 1,000 years. From this list, they chose 11 New Zealand species and five NSW species that…arrow_forwardSometimes introduction of an exotic species upsets native species of the ecosystem.

- Explain at least one (1) adaption that our species may develop to continue surviving on eartharrow_forwardWhich of the following situations has revealed that mutualistic interactions can evolve from prior parasitic relationships? A. Yucca plants are pollinated only by moths of the genus Tegeticula; however, some of the moth species 'cheat" by laying eggs on seeds without pollinating the plant. B. Large-sized lice of the genus Columbicola tended to live on larger species of pigeons. Body size matching had a significant effect on the ability of lice to escape defensive preening by the host bird. C. The nonvenomous yellow-eyed salamander has the same coloration as the toxic California newt. Related nontoxic salamanders which do not mimic the newts are prone to attacks by predators. D. Glochidion trees and Epicephala moths are in an obligate mutualism with each other. Significant cospeciation led to an increase in diversity of the two species.arrow_forwardBiology Introduced Species Directions: Write a short response for each of the following scenarios, describing the effect of the invasive species on ecosystems based on the information in the corresponding graphs.
