How environmental and climatic changes over evolutionary timescales shape island biodiversity patterns

Ever since Charles Darwin's theory of evolution, islands have been central as study systems in the investigation of species distribution patterns and speciation. While Charles Darwin already realized that volcanic islands are dynamic entities, today, their geographical changes over evolutionary timescales are still often overlooked. Especially for ecological and evolutionary studies and theories, the recognition of island dynamics are important. For instance, in the paradigmatic dynamic equilibrium theory of island biogeography formulated by Robert McArthur and Edward Wilson, insular species richness is the consequence of an equilibrium between migration and extinction rates on islands, which are considered as static over time. Recently, Robert Whittaker postulated the General Dynamic model of insular biogeography, in which endemic species richness is related to the ontogenic cycle of volcanic islands; their emergence, growth and subsidence. This model recognizes that islands change over millions of years and that this is crucial to explain species richness patterns. This theory has been recently been complemented by the Glacial Sensitive model headed by José-María Fernández-Palacios. This model predicts that species richness patterns on islands are influenced by climatic change cycles on shorter timescales ranging between 1000s and 100.000s years. The glacial sensitive model also holds that the dynamics of area contraction and expansion, may lead to changing species richness patterns over time and that repetitive island fusions and fissions by sea level change may generate a species pump. Both recent models underscore the realisation that islands change dynamically over timescales and these changes may complement our insight in how insular species disperse, evolve and adapt to continuous environmental change.

Overview: Currently, climate changes or alterations are known to be reflected on the stable isotope ratios of Hydrogen, Nitrogen, Carbon, Oxygen and Sulphur present in atmospheric gas forms, fresh or ocean water, as well as in plants and animals and organi

Objectives: Evolutionary theory provides a framework for understanding all living systems.

Objectives: To introduce participants to the details of communicating science to non-specialized audiences, including, but not exclusive to, public and private stakeholders, students and teachers, and media professionals.

Objectives: Natural history museums are privileged spaces for seminal research on different subjects of biological sciences such as biodiversity, evolution, ecology, biogeography and taxonomy.

Objectives: Provide students with basic workflows, platforms and tools to increase reproducibility at all scientific levels.

Objectives: Under the general framework of Global Change Ecology, the goal of this course is to provide the participants with the most recent and practical knowledge on the use of Functional Diversity.

Objectives: The objective of this course is to introduce participants to the details of communication and writing scientific publications. The main emphasis is on the most common form, the “primary scientific paper”, but other forms will be covered.

Objectives: Lack of fertile land to feed the exponentially growing population, insufficient water availability and quality, changes in the flow of nutrients through the bio-geo-cycles (especially N and P) and climate and land use changes are impacting ecosystem

Objectives: Symbiosis is a key strategy for life on Earth.

Objectives: The goal of this course is to provide to the participants with current and practical knowledge on urban ecology, including ecological and social aspects. It aims at providing an integrated approach on urban socio-ecological systems.

Objectives: Citizen science can be part of the larger process of engaging people in new forms of interaction in scientific research, challenging scientists and citizens whilst enlarging scientific knowledge and providing learning opportunities for all part

Objectives: This course aims at: 1) exploring how scientists can use social media as tools to enhance the communication of their research and the dialogue with society, and 2) discussing the differences that exist in the work of scientists and journalists

Objectives: This course will teach how to apply the SWAT eco-hydrological model to assess the impacts of climate and associated changes on water-soil-plant interactions, and consequences to water resources, soil erosion and nutrient cycles.

Objectives: Provide students with basic knowledge of R programming, allowing them to manipulate and visualize data with R.
