What is an endangered plant species? Why should we care for the endangered plants? If you explore the database there are many native plant species in NJ region listed as endangered species. There are many methods to save the endangered plants. What will be your conservation strategy to save the endangered plants and how can you preserve them in their natural habitat?
Doug Schemske is a biologist who studies plants from around the world. Doug and his research team carry out experiments with the plant species Mouse-ear Cress, or Arabidopsis thaliana. They like this species because it is easy to grow in both the lab and field. Arabidopsis is very small and lives for just one year. It grows across most of the globe and in a wide range of latitudes and climates. Arabidopsis is also able to pollinate itself and produce many seeds, making it possible for researchers to grow many individuals to use in their experiments.
Doug chose Arabidopsis populations in Scandinavia and the Mediterranean for his research on local adaptation because those two locations have very different climates. The populations may have adapted to have the highest survival and reproduction based on the climate of their home location.
To deal with sudden freezes and cold winters in Scandinavia, plants may have evolved freeze tolerance traits, which produces chemicals that act like…

- You are responsible for adding plants to park to make it nice and green, and your only concem is making as much Net Primary Productivity (NPP) as possible. Your assistant has given you a list of potential plant combinations (Options A, B, C, D, or E) they believe might work. You DO NOT know the NPP of the individual plant species. Here is a table with your options. The number in each box represents the abundance (number of individuals) of that plant species for a specific option.

- Agricultural systems typically represent a continuous early successional environment. You can think of it as a newly emerged island waiting to be colonized. This also brings implications for pest management and the species that can establish. What are the characteristics of early successional environments? Are we talking about primary or secondary succession? What are the characteristics of early successional plants? Which kinds do we expect to see in agricultural systems because of this reason? Based on the biodiversity within agricultural systems, what does this mean for insects and resulting pest management?arrow_forwardDuring the past 15 years, white-tailed deer populations in Canada have significantly affected woody plants in forest ecosystems. (a) To estimate white-tailed deer populations in four tracts of the Carolinian forest in southern Ontario, 185 white-tailed deer were captured and tagged with bands. After three weeks, 147 deer were recaptured and 26 had bands. Estimate the population size and show your calculations. (b) To further understand the impact of the deer populations on the woody plants, you decide to study the number of birch trees in an area 100 ha x 100 ha. Using a quadrate measuring 2 ha x 2 ha, you obtain the following results from four random counts: 16, 32, 27, and 11. Calculate the average population density and estimate the total population size of birch trees in the area. (c) Justify the decision to use the mark-recapture method for estimating the deer population size and the quadrat sampling method for the birch tree population.arrow_forwardFor the article "Effects of an invasive predator cascade to plants via mutualism disruption" (https://www.nature.com/articles/ncomms14557) answer the following points: - Summarize the results - What did the author(s) conclude about the question or pattern based on the data? - What are the strengths/weaknesses of the study?

The bird usually buries one to fifteen seeds in a "cache." A typical bird individual will construct over 10,000 caches each year and remember where they are, but only 50-80 percent of the seeds are recovered, depending on the seed harvest and the bird's energy demands. What do you think will happen to the plant's desirable qualities (for example, seed attributes) over time, and why? What do you think will happen to the qualities of the bird that make it an efficient seed disperser throughout time, and why? How do we expect the species to affect each other's evolution?arrow_forwardIn 1876, the US introduced Kudzu to NC to control erosion. Since this time, the vine has taken over and spread at a rate of 1 foot per day, causing the loss of native species. How would Kudzu be most accurately described? O A. As a predator O B. As a non-native species O C. As an alien plant O D. As an invasive speciesarrow_forward
