Look at this hypothetical data set from 2000-2002. Imagine it is from a river in Michigan and it represents a two year data set measuring the abundance of organisms. Imagine that during this time period a pulse disturbance like a black liquor spill occurs on the river, disrupting the community. Using what you learned in lab determine between which two months the disturbance occurred (keep in mind that the abundance may change seasonally) .

Biodiversity: Values & Threats 1. In terms of the number of species in various taxonomic groups, what types of organisms represent thegreatest diversity on our planet? And how do we know we’re not “done” cataloging all of life on earth? 2. When scientists try to estimate the number of species that actually exist on earth today, why is thefigure so variable? 3. Describe the global biodiversity patterns found in relation these parameters:Latitude Precipitation Elevation 4. In a well-crafted paragraph (5-7 descriptive sentences) specifically describe 4 key ways thatbiodiversity benefits mankind. Use examples to support each of your statements.

ResiliencySpecies richnessBiodiversityGamma diversity words to match it with: number of species in an environment, considers number of habitats and total species number among them, combination of species richness and species eveness, same as species eveness, high probability of recovery to original state, high probability of disruption.If you do not understand the text based question, use the image below.
Plot survivorship curves for all three species illustrated in Table 1 on a single graph. Label the axes and provide a clear legend convert it and make use of legend, so for the first species it would be 6months=1unit, then for the second species 1yr=1unit, and the third species would be 50yrs=1unit
Use the information provided: population experiences density-dependent growth K or carrying capacity is 180 r = 0.032 individual/month 1. Calculate how many bugs are added to the population next month when population size is 65? 2. Now keeping the condition of density dependent growth, let's change some numbers: K=270 and r=0.13. If the current population is 125 bugs, how large will the population be in 12 months?

Article readings: Why some animals are more important to ecosystem than others. From the article, list down all the species being described as keystone species and their negative effect when removed from their ecosystem. Define the ‘Keystone species concept” and differentiate it from “morphological species concept”. How does a keystone species plays its role in having a trophic cascade scenario? 1 sentence only.
