Despite the intensity of the fire, some soils remained. Total biomass, species richness, and net productivity were reduced significantly after the initial disturbance. There have not been any more fires since. Twenty years after the fire, there are medium-sized trees and bushes growing, as well as ferns and flowering plants. The forest is in the middle, or intermediate, stage of succession. How has the current stage of succession affected total biomass, species richness, and net productivity of the ecosystem? O Total biomass remained the same, species richness decreased, net productivity remained the same O Total biomass increased, species richness increased, net productivity decreased O Total biomass increased, species richness increased, net…ity of 5000 trout.

Then, revise the model to consider harvesting the whales as a percentage of rM. Give various values for this percentage that lead to extinction and other values that lead to in- creases in the population. Estimate the maximum sustainable yield, or the percentage of rM that gives a constant population in the long term (Zill 2013). roto of 1500 m²/day clearing theProtecting biodiversity 1. What characteristics make a species MORE susceptible to extinction/endangerment? (And conversely,what characteristics of a species would make it LESS susceptible?) 2. How were hunting & fishing laws an important “first step” in conserving biodiversity? 3. How is the endangered species act different from a fish/game law? 4. What important “addition” to our interpretation of what the ESA prohibits was established in 1995?
- Find the flaws! Biodiversity occurs in patterns across the globe. Generally speaking, biodiversity increases as you move away from the equator. Initially, biodiversity increases with elevation. Then, after a certain point, biodiversity decreases. This causes a “diversity bulge” at middle elevations. Threats to biodiversity include habitat loss, overharvesting, the introduction of exotic species, and climate change. Features of an invasive species include fast growth, rapid reproduction, high dispersal ability, the ability to alter growth form to suit current conditions, tolerance of a wide range of environmental conditions, and the ability to live off of specific food types (specialist). Technological innovations can help address many environmental concerns. By “going digital”, companies send bills and other communications over email instead than regular mail. This uses more paper and increases our dependence on trees. Radio-telemetry and GPS devices can be attached to animals to track…Curves A, B, and C show the relationship between species richness (number of species) and NPP (net primary productivity). These three curves represent three separate experiments that took place in the same environment (soil, temperature, and water). The difference between the three curves was the order in which the 20 species were added to the environment. Which experiment required more species to finally add the one key species that contributes a large amount of NPP?
