Chapter 54.3, Problem 3R
Summary Introduction
To review:
The life history strategies that are characterized by Lobelia telekii versus Lobelia keniensis, and life history strategies of guppies in high-predation versus low-predation stream sites.
Given:
The Figure 1 represents related species of genus Lobelia, which have taken different forms in different regions.
Figure 1: Related species of the genus Lobelia.
The predation of guppies at high-predation and low-predation stream sites in Trinidad affects their population, as represented in Figure 2.
Figure 2: Life history of guppies get affected by predation in stream sites.
Introduction:
Life history strategies of different populations differ at species level and population level. Life history strategies vary among two species of Lobelia due to their different habitats and environmental conditions. In case of guppies, the levels of predation make difference in their life history strategies.

Which statement about the classic competition experiments involving two
Paramecium species is FALSE?
The experiment involved interspecific competition.
The experiment involved exploitation competition.
Each species, when grown alone, exhibited logistic growth.
When grown together, the species exhibited logistic growth, but each reached a
lower carrying capacity than when it was grown alone.

- 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,…arrow_forwardHow does a defense mechanism (behavioural, cryptic colouration, protective colouration, mimicry) affect predation and competition? a) Provide an example of a defense mechanism that you have not encountered in the course or in the online assignments. Include an image depicting the defence mechanism, describe the defence mechanism and cite your sources. b) Hypothesize how this defence mechanism may have evolved over time due to pressure from predation and/or competition.arrow_forwardYou've been out in the field collecting data on the predation of holly leaves. You collect 200 leaves in total of which 100 leaves contain one mine, 20 leaves contain 2 mines and 30 leaves contain 3 mines. After close examination with your hand lens and dissecting microscope you categorize a total of 15 mines with round holes, 9 mines that were torn open and 27 mines with an irregular hole. After some basic analyses you conclude that the predation rates by blue tits and wasps are: A. 3.7% and 6.5% B. 6% and 10% C. 10% and 6% D. 4% and 6.5%arrow_forward

- Lake Mendota is a lake with high levels of nutrient input from agriculture that has the potential to fuel blooms of phytoplankton. In 2009 the invasive spiny water flea Bythotrephes (native to Europe and Asia) was first detected in the lake. In the figure, the food web for Lake Mendota prior to the invasion is on the left, and after the invasion on the right. Bythotrephes is a more effective predator of the herbivorous zooplankton Daphnia than the native planktivorous perch (represented by the large red arrows between Bythotrephes and Daphnia), and perch consume Bythotrephes at much lower rates than they do Daphnia (represented by the small red arrows between perch and Bythotrephes).

A. Yucca plants are pollinated only by moths of the genus Tegeticula; however, some of the moth species 'cheat" by laying eggs on seeds without pollinating the plant. B. Large-sized lice of the genus Columbicola tended to live on larger species of pigeons. Body size matching had a significant effect on the ability of lice to escape defensive preening by the host bird. C. The nonvenomous yellow-eyed salamander has the same coloration as the toxic California newt. Related nontoxic salamanders which do not mimic the newts are prone to attacks by predators. D. Glochidion trees and Epicephala moths are in an obligate mutualism with each other. Significant cospeciation led to an increase in diversity of the two species.arrow_forwardat Del or or 1.
