P. 2: "Karposi's sarcoma" should be "Kaposi's sarcoma"

P. 5: "Karposi's sarcoma" should be "Kaposi's sarcoma"

P. 13: Figure 1.7, , in panel a, the text on top of the highest curve should say "...with HIV (= prevalence, P_{a,1998})" ("P" not "i")

P. 148: Parts (b)-(d) of question 4.11 should be corrected as:

(b) Determine the two null clines along which the number of infected individuals,
I, would remain constant.
(c) Add curves for all three of these null clines to the figure, ...
(d) Add two dots to the figure where both variables remain
constant (the two possible equilibria).

P. 164 (right before equation 5.12): "Recipe P1.4" should read "Recipe P1.2".

P. 166 (legend for fig 5.3): "p(t+1) = f(p(t+1))" should read "p(t+1) = f(p(t))"

P. 178 (four lines after equation 5.1.3): "Using this result in the second term..." The derivative that follows should be the first derivative, not a double derivative.

P. 179 (two lines after equation 5.26): "[Use Rules A2.6 and A2.11 to take the derivative of (5.25)..." should read "[Use Rules A2.6 and A2.12 to take the derivative of (5.25)..."

P. 185: Equation (a) in problem (5.1) should have an n(t) added to the right-hand side and should read n(t+1) = n(t) + λ n(t) (1-(n(t)/K)^{θ}).

P. 211, first line: n_{0} = 1 should read n = 1

P. 275, second to last line: "the genetic covariance between mail tail length" should read "the genetic covariance between male tail length"

P. 277: "on both male tail length sexual and" should read "on both male tail length and"

P. 288, eight lines from bottom: "e.g., if B(t) = 0" should read "e.g., if G(t) = 0".

P. 290, Problem 7.1: Assume that all anemones remain alive and that no new ones are born over the time scale of the model.

P. 290, Problem 7.2: "Furthermore, suppose that ... p_{j}." should read "Furthermore, suppose that juveniles survive one time step to become adults with probability p_{j} and that they die with probability 1-p_{j}."

P. 290, Problem 7.3: Hint: Consider Rule P2.25.

P. 291, Problem 7.5: The second differential equation (for dp/dt) should not have a ^ over the Gp term. Hint: Consider Rule P2.25.

P. 301: Five lines up from the bottom should say "matrix (8.10)" not "matrix (8.10b)"

P. 304: Horizontal axis on graph (b) should say y

P. 305, eqn 8.15b: Subscript on second epsilon should be I

P. 305, eqn 8.16a: The last partial derivative should be taken with respect to the function f, not the function g.

P. 317, eqn 8.34a: A partial derivative symbol (∂) is missing in front of the x_{2} in the denominator.

P. 336, eqn 8.49: The term multiplying λ_{1} should read r + h s - r h s not r + s - r h s.

P. 336, eqn 8.50: The denominator should read r + h s - r h s not r + s - r h s.

P. 374, line 2 from the bottom: "...however, the equilibrium population size would be zero according to (9.39); to obtain a nonzero population size,..." should say "...however, the population size would also remain constant if we ignored terms of order epsilon in (9.39); to predict how the population size changes, ..."

P. 383, in problem 9.2: There are two (d) parts to this question, so the parts should be renumbered from (a) to (j).

P. 398: The dotted line is missing; it lies just below the short-dashed curve (see corrected version).

P. 407, below equation (10.18c): λ_{3} should read λ_{3} = -0.3 - 0.3 i

P. 411: The numbers in Table 10.1 are wrong. The corrected entries are:

In the text, "Table 10.1 presents these results, illustrating that an increase in the survival probability from age 3 to age 4 (i.e., p_{3}) has the greatest impact on the population growth rate. Even so, increasing p_{3} by 1% is expected to lead to only a 0.31% increase in the growth rate of the population." should say "Table 10.1 presents these results, illustrating that an increase in the survival probability from age 1 to age 2 (i.e., p_{1}) has the greatest impact on the population growth rate. Even so, increasing p_{1} by 1% is expected to lead to slightly less than a 1% increase in the growth rate of the population."

P. 473: On the third line, for the bell-shaped function, the parenthetical term in the exponent should be squared: exp(-(s_{m}-s)^{2}/a_{α}).

P. 550: In Figure P3.14, the curves are labeled incorrectly, with s^{2} = 0.25 and s^{2} = 4 being reversed. The more bell-shaped curve should say s^{2} = 0.25.

P. 558: The mean and variance of the log-normal distribution are incorrectly reported in Table P3.3. The correct formulae are given by equations (P3.31) and (P3.32) on p. 551.

P. 573: The second to last line should read ''we would draw a random number from an exponential distribution with parameter'' (not with mean)

P. 612: The line before equation (14.7) should read ''Having started in state i, we can write
the probability of eventually being absorbed in state j as'' (i and j are reversed)

P. 632: The first equation (14.53) should be (14.52).

P. 634: The middle line of equation 14.1.1 should read ''ρ_{a,2} = d_{2} ρ_{a,1} + (1-b_{2}-d_{2}) ρ_{a,2} + b_{2} ρ_{a,3}''.

P. 635: In equation 14.1.7, the upper limits of the sum should read ''i-1'' not ''i=1''

P. 636: Problem 14.4(c) should read ''(c) What are your answers to part (b) when the extinction rate is the same for both early and late successional forests (e_{2} = e_{3} = e)?''

P. 652: Above (15.6), change ''Specifically, diffusion models assume that'' to ''Specifically, diffusion models assume that the parameters u and d can be scaled such that", and below (15.6), change ''where μ and σ^{2} are finite numbers (with σ^{2} > 0).'' to "where μ and σ^{2} are finite numbers (but μ may be zero). For example, in this migration model, we can obtain a diffusion if we assume that difference between u and d shrinks as the spatial scale shrinks such that (u-d) is of order Δ_{x}, but both u and d themselves remain relatively large (bounded away from zero).''

P. 669: In equation (15.23), the a_{x} should be a_{k}, and the + sign before c_{2} should not be superscripted.

P. 670: Note after (15.24): it is interesting that the stationary distribution does not depend on the mutation rate (μ) or the mutational effect size (ν), only on the strength of competition and the population size.

P. 671: Note for Box 15.3: the Wright-Fisher model described here represents the ''idealized'' case where the population size is constant and parents are randomly chosen to give birth. This is the standard comparison against which more biologically realistic population dynamics are compared, through the introduction of the concept of an ''effective poulation size'', N_{e}. For non-ideal populations, N_{e} is chosen (where possible) such that the extent of random fluctuations in allele frequency would be the same as that in the idealized model (as given by σ^{2}).

P. 690: The book suggested by Lande et al. (2003) is missing the middle author, S. Engen (apologies!).

P. 704: The sixth line from the bottom should read "that g'(a) is not zero" rather than "that g(a) is not zero".

P. 713: After equation (A4.3), it should be noted that "If d^{2}W/dz^{2}|_{z=z*} = 0, higher-order terms must be examined to determine whether z* is a maximum."
