Determining the response of plant functional and phylogenetic diversities to changes in management in lowland fens: implications for ecosystem processes and environmental change

Sala 2.2.14, FCUL, Lisboa

Human pressure on fen peatlands has created the need to implement management practices to restore and reconnect fragmented fens. However, the way in which different components of biodiversity respond to changes in land use and management is still poorly understood. A key research question is how functional and phylogenetic diversities of fens respond to changing levels of management. Understanding the consequences of management for fen vegetation composition is vital, not only for explaining the impacts of disturbance on biodiversity and ecosystem processes, but also for elucidating how such habitats may respond to future environmental change. Here, we use linear mixed-effects models and a combined measure of functional-phylogenetic diversity and show that phylogenetic diversity is more sensitive to management effects than functional diversity. High levels of disturbance resulted in plant communities with significantly lower phylogenetic diversity than relatively undisturbed sites. Management promoted a filtering effect of phylogenies and traits that are capable of tolerating such disturbance levels. These results have implications for the long-term management of lowland fens, since intensifying disturbance of ecosystems can lead to reduced resilience and increased vulnerability to future 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.
