Workshop 1: Scientific Illustration - Techniques in black and white (Instructor: Davina Falcão)
Duration: 4 hours Objective: It is intended to demonstrate the most common techniques to illustrate an animal species, from shape to shaded.
Workshop 2: Scientific Illustration - Field Design (Instructor: Davina Falcão)
Duration: 4 hours Objective: It is intended to demonstrate how to draw an animal correctly from direct observation. Special focus on anatomy and proportions.
Workshop 3: A primer in occupancy-detection for herpetology (Formador: Mário Ferreira)
Duration: 3 hours Objectives: Observing and counting individuals of amphibian and reptile species can be difficult due to various factors such as cryptic behavior, staining patterns, or observer experience. Not taking into account undetected individuals will introduce errors in data analysis and compromise our ability to detect environmental factors affecting the abundance/distribution of species. Occupancy-detection modelling is a framework that explicitly accounts for variation in the detection probability and models the occupation probability by incorporating information from covariables. In this workshop, we introduce the problem of imperfect detection and the tools available under the occupation-detection framework. We also analyse a few examples for the main classes of occupation-detection models using simulated data sets in the package unmarked from R.
