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.

Draw a species accumulation curve for the beetles in Area C3, based on the data shown in Table 1. Ensure that you calculate a standard deviation around each average number of species per sample; plot this on this figure. Make sure you label the axes and that you provide a legend
Create a two-part figure showing the effects of forest fragmentation on the community of small mammals relevant to Lyme disease in eastern forests. Figure A should depict the interaction network of a large forestpatch with higher species diversity. Figure B should illustrate how the interaction network and transmission of Borrelia burgdorferi are different in a small forest fragment with low species diversity than they are in largeforest patches with greater diverisity. Eastern forests are diverse communities in which many species interact with one another. Your figure will be asimplified interaction network showing some of the most important species related to the ecology of Lyme disease. Remember that your goal is to illustrate how increasing fragmentation affects forest mammal communities in a way that increases Lyme disease risk.• Choose from the following species for your figure: black-legged tick, white-footed mouse, raccoon, eastern chipmunk, gray squirrel, white-tailed deer,…

Many invasion process models (including the framework in Blackburn et al. 2011) have emphasized that successful "establishment" of a non-native species requires that species successfully _____________ and ______________ in the introduced range.

How is fire ants current range likely to change as a result of climate change? Things that you don't want to miss in your answer to get a high score: Define any terms such as range, niche. Do they prefer or are they limited by weather? What happens to their spread as weather changes The evidence for their limitation by cold weather is in the reading, and you should know that some species, particularly invasives, may spread as the climate warms.
The Tinamous distribution may shift northward if its realised niche allows.
What does the data suggest? What does anova P = .45 means? Could you explain the above details in this context Context - The study aims to test the role of priority effects in fruit fly communities. I tested whether the timing of one species arriving at a particular site causes any alteration to the environment, making it more or less desirable for a second species to come.

Seagrass meadows and vulnerable species in Pacific Islands and BahrainSeagrass meadows have profound impacts on sustaining vulnerable species such as dugongs and turtles. The aim of this assignment is to provide you three studies (two article and a chapter) dealing with seagrass in Pacific and Islands and Bahrain and the Arabian Gulf. Question: What are the differences between the populations of dugongs and turtles in both regions? -What are the main ecological goods and services provided by seagrasses in both regions based on the material, no-material and regulating services?

INTERPRET DATA Examine the top and middle graphs in Figure 54-5. Are these examples of exponential or logistic population growth? Where is K in each graph? (You may need to refer to Chapter 53 to answer these questions.) RESULTS AND CONCLUSION: The top and middle graphs show how each species of Paramecium flourishes when grown alone. The bottom graph shows how they grow together, in competition with each other. In a mixed culture, P. aurelia outcompetes P. caudatum, resulting in competitive exclusion. SOURCE: Adapted from G.F.
