Question

Will Competition with a Native Mosquito Species Prevent the Spread of an Introduced Mosquito? Suppose the researchers want to use the data collected from their experiments on the competition between the non-native mosquito Aedes albopictus and the native mosquito A. triserigtus to better control the population of the non-native species. Suppose the researchers decide that the best way to control the population of the non-native species is to artificially increase the carrying capacity of the native species. To do this, they first need to calculate a new carrying capacity for the native species. The original data are shown in the table below. Water obtained from tree holes Water obtained from tires Competition coefficients a=0.43 a = 0.84 B = 0.72 B = 0.25 Carrying capacities (no. individuals/100 ml of water) K1 = 42.5 K1 = 33.4 K2 = 53.2 K2 = 44.7 Question 1. Use the data in the table and in-text Equations 14.2 and 14.3 to determine the minimum carry capacity (K1) that would be needed to allow species 1 to outcompete species 2 in the tree hole communities. Plot the new isoclines for species 1 and species 2. Label your axes. Eqn. 142 is N1=K1-aNz and Eqn. 14,3 is N2=K2-BN1 Question 2. Use the data in the table and in-text Equations 14.2 and 14.3 to determine the minimum carry capacity (K1) that would be needed to allow species 1 to outcompete species 2 in the tires. Plot the new isoclines for species 1 and species 2. Question 3. What other option might the researchers employ to control the non-native mosquito species? Explain the pros and cons of this alternative control method.

don't need to know n1 or n2

14.2 equation N1=K1-(alpha)N2

14.3 equation N2=K2-(beta)N1

I need help with all of the questions.

Answer 1

HP =rk, ~AN2 At equilibrium duco, TN2 = r k k No a certain = 60.48) – 98-83 dela Ky - BN, => 0 = (-BN,) > N.-&-/B)-532 Sin Me ty, & Species 2 loss prejel I was 0.72 = 73.89 N127389, Kız 42.5 species a loss I M = 98.83 Kg = 83.2 species a win So, for Speciest (4) species a to win over speares 2, the K new K, Shored be 98.83. h oiSo,

Hope it's clear..thanks
