title: "Quantitative methods for population dynamics"
description: "A two-day workshop with `R`"
site: distill::distill_website
---
```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = FALSE)
```
**What**: Quantifying population dynamics is crucial for the conservation and management of animal and plant species. This workshop deals with the analysis and modelling of population dynamics. In this introductory workshop, we will cover population projection matrix models and population viability analyses, the estimation of demographic parameters (e.g. survival, dispersal) using capture-recapture models and the estimation of population density and abundance using capture-recapture, N-mixture and distance sampling models. Our hope is to provide you with what you need to go your own path. The event is free of charge, and video-recorded.
**For whom**: This is a workshop for ecologists. Basic knowledge of `R` is required. See [R for beginners](https://cran.r-project.org/doc/contrib/Paradis-rdebuts_en.pdf) by E. Paradis for an introduction.
**How**: The format of the workshop will be a combination of lectures and live demonstrations in R with packages `popbio`, `Distance`, `RMark`, `AICcmodavg` and `unmarked`.
**Who**:
+ Lecturers: [Olivier Gimenez](https://twitter.com/oaggimenez), [Aurélien Besnard](https://twitter.com/abesnardEPHE) and [Sarah Cubaynes](https://twitter.com/sarahcubaynes).

### Schedule
**June 1, 2023**
9am-9:50am - Introduction, conventional methods and the detectability issue, capture-recapture for closed populations part 1.
10am-10:50am - Capture-recapture for closed populations part 2.
11am-11:50am - Distance sampling.
2pm-2:50pm - N-mixture models.
3pm-3:50pm - Survival estimation.
4pm-4:50pm - Survival estimation with covariates.
**June 2, 2023**
9am-9:50am - Capture-recapture multistate models.
10am-10:50am - Count-based PVA.
11am-11:50am - PVA with matrix models - determinist.
2pm-2:50pm - PVA with matrix models - stochastics.
3pm-3:30pm - Conclusion.
### Requirements
+ Install [`R`](https://cloud.r-project.org/) and [`RStudio`](https://rstudio.com/products/rstudio/download/#download). `RStudio` is recommended but not mandatory.
+ Install the R package `RMark` following the steps described at <http://www.phidot.org/software/mark/rmark/>. For Mac users, the installation is a bit tricky, check out the procedure [here](tutorials/rmark-mac.html).
+ Install the R packages `unmarked`, `Distance`, `AICcmodavg` and `popbio` directly from the console with
```{r eval = FALSE, echo = TRUE}
install.packages(c("unmarked", "popbio", "Distance", "AICcmodavg"))
```
