Chapter 15 Further Issues II: Importing IPMs and Function-based MPMs
More and more of our imports come from overseas.
It is relatively common for population ecologists running matrix projection analyses to find themselves wanting to build IPMs and function-based MPMs (fbMPMs) published by other authors. For example, users might find themselves reading an interesting paper utilizing IPMs, such as Childs et al. (2003) or Dahlgren & Ehrlén (2011), and wanting to replicate the analyses. Fortunately, lefko3 includes tools to make this relatively easy.
The strategy used in lefko3 is to take all of the characteristics of an IPM or a fbMPM and input those characteristics as data in a vrm_input object. This S3 object is essentially a list that contains up to 13 elements, most of which are structured data frames that need to be edited manually. The function that creates these objects is vrm_import().
To use function vrm_import(), users should first determine the monitoring occasions or years for which information will be entered, the number of patches to be covered, whether there are any stage groups, which vital rate models should be developed, whether information is provided for interactions between independent terms, whether any independent factors are categorical, and the distributions and associated parameters assumed for size and fecundity. Although a stageframe is not required to create vrm_input objects, a stageframe will be required to create the IPMs, fbMPMs, or projections resulting from them, so users should pay serious attention to creating realistic stageframes.
Let’s consider this process using the simplest vrm_input object, which includes only terms for main effects, three years, and a single patch, with Gaussian primary size and fecundity. Let’s say that our monitoring occurred over the years 2020, 2021, and 2022. This yields only two years at time t, since 2022 is the final year of data and so is the ultimate year in time t+1. So we will include only those two years in the input options.
vrm_example <- vrm_import(years = c(2020, 2021))

Our example vrm_input objects is a list holding only 7 elements. The first, vrm_frame, is a data frame holding the main effects factors that we can set for each of up to 14 vital rate models. The 14 vital rate models are the same as those listed in chapter 5 on function-based MPMs: survival (surv), observation status (obs), primary size (sizea), secondary size (sizeb), tertiary size (sizec), reproductive status (repst), fecundity (fec), juvenile survival (jsurv), juvenile observation status (jobs), juvenile primary size (jsizea), juvenile secondary size (jsizeb), juvenile tertiary size (jsizec), juvenile reproductive status (jrepst), and juvenile maturity status (jmatst). We see rows in which we can alter the coefficients to be used in linear models of vital rates, including the y-intercept (intercept), primary size in time t (size2), tertiary size in time t-1 (sizec1), spatial density (density), etc. The general strategy is for users to change the coefficients that they have explicit values for, and to leave the rest as 0.
Object year_frame allows us to set specific coefficients for each year associated with each vital rate model. This is particularly useful as the IPM in question used a mixed modeling approach with year as a random term, although it serves the same function with year as a fixed categorical term. Object patch_frame functions in the same way, except for patches or subpopulations (we do not currently offer a top-level population category, but the patch level can be used for populations if the latter are not to be subdivided). Objects group2_frame and group1_frame provide coefficients associated with different life history stage groups in times t and t-1, respectively, if such information is provided and stages are grouped in a way that is incorporated into linear modeling.
Object dist_frame gives the distribution of each vital rate model’s response term. Any vital rate that uses a linear model for estimation needs to be set to binom (for binomial distribution), gaussian (for the Gaussian distribution), gamma (for the gamma distribution), poisson (for the Poisson distribution), or negbin (for the negative binomial distribution). Unused vital rates should be set to constant. Object st_frame allows the user to set \(\sigma\) if the distribution is Gaussian, or \(\theta\) if the distribution is negative binomial (all other cases should be left as 1).
Let’s now take a look at some examples.
15.1 Generating standard ahistorical IPMs and function-based MPMs
Let’s start off by recreating the ahistorical IPM set up in Chapter 7. This example will focus on Lathyrus vernus (section 1.8.2). To remind ourselves of this plant and its dataset, let’s take a look at a data summary. Note that in a real example from the literature, we might not have the original dataset to work with, but would need to infer certain characteristics about the dataset from the publication.

The data were collected over four years - 1988 through 1991. Size is given in two formats - either by the total leaf volume (Volume), or by the natural logarithm of the total leaf volume (lnVol). Let’s use the total volume for this example. We also need to note the minimum and maximum size, and whether an unobservable size class is included. The minimum leaf volume appears to be be 1.8, while the maximum appears to be 7032.0, and the literature on this plant shows that it can experience vegetative dormancy, during which there would be no aboveground tissue and hence leaf volume would be 0.
As before, we need to create a stageframe describing the life history and the actual stages that will compose the discretized IPM. We do so below, utilizing the information that we have gleaned from the publication, and then show four key variables within that output. Note that this stageframe covers a complex IPM, involving 100 size-classified stages and three stages that do not fit in the size gradient (dormant seed, seedling, and vegetative dormancy).

To be useful, publications involving IPMs need to show the parameterizations of their kernels, which are generally composed of vital rate models. These parameterizations vary in complexity, as different authors have different preferences for developing vital rate models. Some choose approaches involving splines or general additive modeling - these approaches produce potentially complex patterns and are difficult to characterize except via saved data structures describing the localized relationships between independent terms and response (for an excellent example of a well-done non-linear IPM, see Garcia et al. 2011). Other approaches utilize linear modeling, and may involve generalized linear modeling (GLM) or generalized linear mixed modeling (GLMM) (e.g., Dahlgren & Ehrlén 2011; Shefferson et al. 2014). Package lefko3 is currently set up to allow imports of GLM and GLMM models. We anticipate developing methods to import spline-based kernels in the near future.
Let’s assume that our IPM is composed of a kernel that is itself composed of four vital rates: survival probability, sprouting probability, size transition, and fecundity. The kernel for a typical sprouting individual would be given as the following.
\[\begin{equation} K(x_j, x_i) = s(x_i, t) r(x_j, t+1) g(x_j, x_i) + f(x_i, t) \tag{15.1} \end{equation}\]
Here, \(s(x_i, t)\) is the survival of an individual of discretized size \(x_i\) at time t to time t+1, \(r(x_j, t+1)\) is the sprouting probability of an individual in discretized size \(x_j\) at time t+1 that has survived from time t, \(g(x_j, x_i)\) is the probability of size transition from discretized size \(x_i\) at time t to discretized size \(x_j\) in time t+1 assuming survival and sprouting, and \(f(x_i, t)\) is the average offspring production in time t+1 of an individual in discretized size \(x_i\) at time t. For a vegetatively dormant individual, the kernel differs because a lack of sprouting prevents any size transition or offspring production from occurring, as in the following.
\[\begin{equation} K(x_j, x_i) = s(x_i, t) (1 - r(x_j, t+1)) \tag{15.2} \end{equation}\]
Next we need to scour the publication to find the definitions of the vital rate models defining the kernels. In our case, this means finding the slope coefficients and response distributions for all vital rate models used, including survival probability, sprouting probability, size transition, fecundity, etc. The probability distributions, as shown in our IPM chapter (chapter 7), should be binomial for vital rates such as survival, observation status (sprouting), reproductive status, and maturity status. They could be Gaussian, gamma, Poisson, or negative binomial for size and fecundity, or might be zero-truncated or zero-inflated versions of the Poisson or negative binomial. We also need to know whether juvenile vital rate models will be used, and what those distributions correspond to.
Chapter 7 provides model summaries (just preceding section 7.2.4). For this example, following the model summaries in the IPM chapter, we see that we need survival, observation status, size transition, and fecundity, and that we will also use juvenile survival, juvenile observation status, and juvenile size transition to model the seedling class. The modeling approach is the generalized linear mixed model, with year as a random categorical factor.
Let’s start off by building a skeleton vrm_input object. Note that we input only the years capable of being transitioned from in the dataset, which means the three years 1988, 1989, and 1990. We will make this object a bit bigger than before, because we will allow fecundity to be zero-inflated (setting zi = TRUE will add seven new columns governing the zero-inflation binomial model for all parameters capable of being zero-inflated). We will also set use.juv = TRUE to change some defaults to allow the use of juvenile transitions. Here is the code to produce our skeleton object.
lath_vrm <- vrm_import(years = c(1988:1990), zi = TRUE, dist.fec = "negbin",
use.juv = TRUE)

Now that we have our skeleton vrm_input object, let’s take a look at the vital rate models. In a typical publication, the authors might present equations showing the linear relationships among terms. Alternatively, they may present some of the output from modeling, giving us the slope coefficients. Since chapter 7 includes the latter, let’s instead assume that we have a paper that presents the vital rate models as equations. Below, we see how the survival and sprouting models might be presented, using the real estimated terms.
\[\begin{equation} logit(s(x_i, t)) = 2.32571 + 0.00109 size(t) + year(t) + indiv(i) \tag{15.3} \end{equation}\]
\[\begin{equation} logit(r(x_j, t+1)) = 2.230 + year(t) + indiv(i) \tag{15.4} \end{equation}\]
In these models, we see that both are binomial models using the logit link. Both have y-intercepts (2.32571 in the case of survival, and 2.230 in the case of sprouting). The survival model involves a relationship with size in time t, and that relationship is linear with a slope of 0.00109. Both equations include categorical values for year in time t and individual, because both survival and sprouting probabilities were estimated as mixed models with year in time t and individual as random terms. Let’s input all of the main terms into our skeleton vrm_input object, particularly getting the y-intercepts and slope coefficients into the appropriate parts of the vrm_frame. Let’s also change the distribution of the sprouting model from constant (the current setting) to binom.

Year is a random term in both cases, meaning that the average effect of year has actually already been absorbed by the y-intercept and the mean of the year terms should be approximately zero. So, if we cannot find these terms in the paper, then we can simply assume it is 0, or we can produce random numbers if we have information on the variance of the year term in the model. In our case, we see in the output for the survival and sprouting models in the IPM chapter that the standard deviation of the year term is 0, meaning that these coefficients were inestimable under the mixed structure used. So, we will skip adding these terms here. Because we are not interested in predicting individual survival probabilities, we will also not incorporate any individual terms.
Let’s move on to size. Our size model has a Gaussian response and so uses the identity link. Thus, our predicted size in time t+1 is given by the equation below.
\[\begin{equation} E(size(x_j, t+1)) = 164.0695 + 0.6211 size(z_i, t) + year(t) + indiv(i) \tag{15.5} \end{equation}\]
The probability of becoming size j in time t+1 assuming a Gaussian distribution is the following.
\[\begin{equation} g(x_j, x_i) = \frac{1}{\sqrt{2 \pi} \sigma(x_j)} e^{-E(size(x_j, t+1))} \tag{15.6} \end{equation}\]
Our size model includes year terms, which are 96.3244, -240.8036, and 144.4792 for years 1988, 1989, and 1990. We also see that \(\sigma = 503.6167\), which is shown as the standard deviation of the residual component in the random effects section of the model summary output. We will add these terms below. Note that primary size is set to the Gaussian distribution by default.

Zero-inflation models are actually composed of two linear models - a binomial model governing the occurrence of excess zeros, and a second conditional model with the target distribution covering all non-zeros and a smattering of regular zeros (in this case, a negative binomial with a log link). So, we will need to parameterize both. Here are the two models, as shown in the model output summary in chapter 7.
\[\begin{equation} logit(f(x_i) = 0) = 6.252765 - 0.007313 size(t) + year(t) + indiv(i) \tag{15.7} \end{equation}\]
\[\begin{equation} log(f(x_i) \geq 0) = 1.517 + year(t) + indiv(i) \tag{15.8} \end{equation}\]
The dispersion parameter for the negative binomial is \(\theta\), and we see in the IPM chapter that this is given as 0.2342114. The year terms for the zero-inflation binomial model are \(3.741475 \times 10^{-7}\), \(-7.804715 \times 10^{-8}\), and \(-2.533755 \times 10^{-7}\) for 1988, 1989, and 1990, respectively. The year terms for the conditional model are -0.41749627, 0.51421684, and -0.07964038, respectively. Let’s incorporate all of these values.

> [1] "vrm_input"Next we will need to input the associated parameters for any other model included in the IPM. Particularly, we know that vital rate models were also estimated for seedlings, and that these models were incorporated as juvenile vital rate models. The juvenile vital rates include survival, sprouting, and size transition. The equations for these models are as follows.
\[\begin{equation} logit(s_{juv}(x_i, t)) = 1.03 + year(t) + indiv(i) \tag{15.9} \end{equation}\]
\[\begin{equation} logit(r_{juv}(x_j, t+1)) = 10.390 + year(t) + indiv(i) \tag{15.10} \end{equation}\]
\[\begin{equation} E_{juv}(size(x_j, t+1)) = 3.0559 + 0.8482 size(t) + year(t) + indiv(i) \tag{15.11} \end{equation}\]
Together with the residual \(\sigma\) for the size model and year terms for sprouting and size, let’s add all of these terms to our vrm_input object.

15.1.2 Fitting vital rate models to matrix estimation functions
At this point, we have created all of our main IPM vital rate model inputs. However, there are still a few missing pieces that we need to fit in order to create the IPM properly. Our next step is to include instructions that tell lefko3 how the vital rate models fit together. Let’s see how this works.
By default, elements in survival-transition matrices created by functions flefko2(), flefko3(), aflefko2(), and fleslie() are estimated via the following two kernels, the first for adults and the second for juveniles.
\[\begin{equation} e_{j, i} = surv_{kernel} obs_{kernel} sizea_{kernel} sizeb_{kernel} sizec_{kernel} repr_{kernel} \tag{15.12} \end{equation}\]
\[\begin{equation} e_{j, i} = jsurv_{kernel} jobs_{kernel} jsizea_{kernel} jsizeb_{kernel} jsizec_{kernel} jrepr_{kernel} jmatst_{kernel} \tag{15.13} \end{equation}\]
Here, \(e_{j, i}\) refers to the element at the jth row and the ith column. The terms to the right of the equal sign refer to the values developed by kernels representing different vital rates. So, \(surv_{kernel}\) is the kernel developing the probability of survival, \(obs_{kernel}\) is the kernel developing the probability of observation (or sprouting), \(sizea_{kernel}\) is the probability of size transition in the primary size variable, \(sizeb_{kernel}\) is the probability of size transition in the secondary size variable, \(sizec_{kernel}\) is the probability of size transition in the tertiary size variable, and \(repr_{kernel}\) is the probability of becoming reproductive or its complement. The juvenile kernel is composed of similar vital rate kernels, but also includes \(jmatst_{kernel}\), which is the probability of becoming mature.
Package lefko3 uses the vital rate kernels above to produce values in essentially all cases, and so vital rate kernel values can shift to a constant value of \(1\) if a vital rate is not used. There are also circumstances in which vital rates may be fixed to 0 or even other constants, though these are relatively rare (this may occur is a juvenile size class is not utilized, because then juvenile vital rates should generally equal zero during matrix creation). The key is to fix unused vital rates to constant values of \(1\). We do this by changing the y-intercepts of unused vital rate models to exactly 1, and changing the distribution listed for the vital rate in dist_frame to constant. Note that we do not need to bother doing this with zero-inflation components of unused vital rates. In our case, all unused vital rate models are already set to constant, so we will just change the intercepts to 1.

Finally, let’s build our IPM using the flefko2() function.
lathmat2_importipm <- flefko2(stageframe = lathframeipm, modelsuite = lath_vrm,
supplement = lathsupp2, reduce = FALSE)
summary(lathmat2_importipm)
>
> This ahistorical lefkoMat object contains 3 matrices.
>
> Each matrix is square with 103 rows and columns, and a total of 10609 elements.
> A total of 26926 survival transitions were estimated, with 8975.333 per matrix.
> A total of 600 fecundity transitions were estimated, with 200 per matrix.
> This lefkoMat object covers 1 population, 1 patch, and 3 time steps.
>

> Max. 1.000 1.000 1.000Users exploring the output and comparing against the original published IPM will notice that the element values are almost the same, but differ by tiny amounts (often on the order of 10-5 or smaller). These small differences occur because of the rounding that happens when authors publish their models, and are not a cause of concern nor will they cause dramatic differences in inference.
15.2 Importing complex IPMs and fbMPMs
Users may wish to import more complex structures using further terms or interactions. The approach above works in these cases, as well. For example, suppose that we wished to import the historical IPM for Lathyrus shown in the IPM chapter (chapter 7). That IPM involves models with historical size and some two-way interactions. We can also produce imported IPMs for this more complicated case, but need to expand the vrm_input object by noting interactions = TRUE in the input to that function, as below.
lath3_vrm <- vrm_import(years = c(1988:1990), interactions = TRUE, zi = TRUE,
dist.fec = "negbin", use.juv = TRUE)

Our new vrm_input object is bigger. The difference in size is a direct result of an increased number of rows in the vrm_frame element: previously, that data frame held 17 rows, but now it holds 128. The first 17 correspond to the main effects, as before, while the remaining 111 rows correspond to the two-way interactions.
Let’s start off by changing the distributions, as before.
Now let’s take a look at our vital rate models. The equations are as follows.

stageframe = lathframeipm, historical = TRUE)Finally we can produce our historical IPMs. Because they will be huge, we will create them in sparse format (standard matrix format will lead to an object around 7 gigabytes in size).
lathmat3_importipm <- flefko3(stageframe = lathframeipm, modelsuite = lath3_vrm,

As before, we can use this IPM in any way that might use a normal fbMPM in lefko3. The general approach shown above can also be used to develop age-based (Leslie) or age-by-stage function-based MPMs.
15.3 Running projections from imported IPMs and fbMPMs
The vrm_input approach can also be used to run custom function-based projections.
lath_proj <- f_projection3(format = 3, stageframe = lathframeipm,
supplement = lathsupp2, modelsuite = lath_vrm, nreps = 10, times = 10,
stochastic = TRUE)
> Warning: Option patch not set, so will set to first patch/population.
summary(lath_proj)
>
> The input lefkoProj object covers 1 population-patches.
> It is a single projection including 10 projected steps per replicate, and 10 replicates, respectively.
> The number of replicates with population size above the threshold size of 1 is as in
> the following matrix, with pop-patches given by column and milepost times given by row:

> [1] NALet’s take a look at what our projection replicates look like (figure 15.1).

15.4 Points to remember
- Users may import IPMs and fbMPMs into
lefko3if they are presented as kernels of linear models, with functionvrm_import(). - Imported IPMs and fbMPMs may also be loaded into projections, including function-based projections that create new matrices at each time step with function
f_projection3().
