Read the abstract from the scientific journal article: Helfield, JM and RJ Naiman. 2001. Effects of salmon-derived nitrogen on riparian forest growth and implications for stream productivity. Ecology 82 no. 9: 2403-2409. From this Abstract section, select all below that correctly identify conclusions of this paper. Growth rates are significantly increased in Sitka spruce near spawning streams. Trees and shrubs near spawning streams derive -34-43% of their foliar nitrogen (N) from spawning salmon. Trees and shrubs near spawning streams derive-22-24% of their foliar nitrogen (N) from spawning salmon. Riparian forests affect the quality of instream habitat through shading, sediment and nutrient filtration. Riparian forests affect the quality of instream habitat by producing woody debris, a fertilization process that enhanced streambank production but also serves to improve streams for spawning and rearing of young salmon. Growth rates of Sitka spruce near spawning streams were no different than growth rates near non-spawning streams.

Examine the situation below. What function/services of the ecosystem is highly depicted in this situation? Justify. For 3-5 sentences only* One of the wetland ecosystem which is subjected to this degradation and considered as heavy polluted lake in the Philippines Laguna de Bay (LDB) (Framework for Philippine Plant Conservation Strategy and Action Plan retrieved 2018). LDB is the largest lake in the country and amongst the largest in Southeast Asia. It is a significant natural resource, being the catchment of an expansive and environmentally important watershed (Israel 2007). The shorelines of LDB serve as important locations for industrial, commercial and tourism activities in the country. It plays an ecological importance because it serves as spawning areas for fish and a natural protection from floods
Which of the following statements is supported by the results of studies at the Hubbard Brook Experimental Forest? a. Most of the energy captured by primary producers is lostbefore it reaches the highest trophic level in an ecosystem. b. Deforested watersheds experience significantly less runoffthan undisturbed watersheds. c. Deforested watersheds lose more calcium and nitrogen inrunoff than undisturbed watersheds. d. Nutrients generally move through biogeochemical cycles veryquickly. e. Deforested watersheds generally receive more rainfall thanundisturbed watersheds.
Are the below statements true or false (correct or wrong)? You have briefly to motivate your answer using graphs and/or arguments. a) A specific forest area is discovered to be an important habitat for a certain variety of snakes. Thus, the optimal timber rotation time should be extended. b) Assume a mine extracting both copper and silver. If the price of copper falls and the mine managers decides to increase the production of silver, silver then represents a socalled by-product. c) A rise in global demand for copper will shorten the reserve life of a given copper mining operation. d) If a farm grows two different crops and the price of one of the crops increases, the production mix will shift towards reduced production of the crop that has become more expensive.

7) The term "preemptive competition" refers to _________________. Question 7 options: when individuals of one species inhibit individuals of another by consuming a shared resource situations where the occupancy by one individual precludes the establishment of others when one organism grows over another, thereby inhibiting access to some essential resource when chemical growth inhibitors inhibit germination and establishment of other species when nonterritorial meetings between individuals negatively affect one or both of the participant species

In the year 2000, specimens of Caulerpa taxifolia,a green alga used in tropical aquariums, were found off the coast of California. Native to the Indian Ocean, C. taxifolia is known for aggressive growth and an ability to compete with sea grasses.lt is currently on an international list of invasive species. Which of the following best predicts the consequences of the introduction of C. taxifolia to the California coast? nd 2 school Without natural herbivores or competitors,C. taxifolia will grow rapidly and crowd out native species of producers. C. taxifolia will have a hard time establishing itself because it will have to compete against native species of sea grasses, which are better adapted to the environment. C. taxifolia will grow rapidly, leading to an increase in the diversity of producers. Because it is not in the Indian Ocean, its natural environment, C. taxifolia will not be able to grow efficiently The practice of crop rotation uses nitrogen fixation to create fertile fields.…
