Description
We live in a world where environmental conditions are constantly changing due to various human pressures. Ecological connectivity—the degree to which the landscape facilitates the movement of organisms, gametes, and ecological processes—is essential for ecosystem functioning. However, it is threatened by habitat loss, fragmentation, and degradation. Analyzing and assessing ecological connectivity are crucial for conservation planning and spatial prioritization, ensuring species persistence and ecosystem resilience. Today, ecological connectivity is a key component of international conservation and ecosystem restoration goals, such as the Sustainable Development Goals (SDGs) and the Kunming-Montreal Global Biodiversity Framework, including its "30x30" target.
This course introduces the theoretical foundations of ecological connectivity studies and their spatial analysis, with a primary focus on the R package “Makurhini" (Godínez & Correa, 2020). This package is specifically designed to calculate landscape fragmentation and connectivity indices, which are widely used in conservation planning. Makurhini provides a set of functions to assess the connectivity of protected area networks and the importance of different landscape elements in maintaining connectivity. Additionally, it allows the analysis of scenarios under landscape connectivity changes and incorporates territorial heterogeneity as a limiting factor. The course is aimed at individuals interested in connectivity analysis, taking advantage of the processing capabilities and innovative metric calculations implemented in Makurhini. n this course, we will use the R programming language and its development environment, RStudio, both of which are open-source alternatives, making them legally and easily accessible for governmental, educational, and research institutions.

Objectives
General
Strengthen participants' skills in the theoretical and methodological foundations of ecological connectivity analysis, using open-source software tools, particularly the R package Makurhini, to assess and plan landscape connectivity in conservation and restoration contexts.
Specific
- Explain the fundamental concepts of ecological connectivity and its importance for conservation and ecosystem resilience.
- Introduce the main approaches and metrics used in landscape connectivity analysis.
- Teach the use of the Makurhini package to calculate fragmentation and connectivity indices.
- Facilitate the interpretation of results and their application in conservation and ecological restoration planning.
Course methodology
The course combines a theoretical and practical approach, with a stronger emphasis on developing applied skills. The first part of the course will cover the theoretical foundations of ecological connectivity and its implications for conservation and ecosystem restoration. However, the majority of the course will focus on the practical application of these concepts through the use of the Makurhini package and other spatial analysis tools. Active learning will be encouraged through case study analyses presented by the instructor and potential guest speakers, as well as group discussions to reflect on challenges and applications in different contexts. Additionally, participants will develop a research project where they will apply the methodologies learned to address a real ecological connectivity issue, promoting experiential learning and the development of applied solutions.
Important:- All synchronous sessions will be recorded and published on the redbioma website.
- Final research projects will be published on the redbioma website.

Evaluation
Students will complete assignments and a final project. Evaluation items are as follows:
Item | Value (%) |
---|---|
Synchronous classes | 40 |
Assignments | 25 |
Final project | 35 |
Total | 100 |
Assignments must be submitted by 12:00 PM (GMT-6) on the day before the next class.
The final project consists of applying the knowledge acquired throughout the course to a topic of interest chosen by each student. The instructor will provide spatial data from a set of landscapes with different contexts where the acquired concepts can be applied. However, students are also welcome to use their own data for their final project presentation.
