Essential biodiversity change indicators for measuring the effects of Anthropocene in ecosystems

Sala 2.2.14, FCUL, Lisboa

During the Anthropocene Era, we expect most ecosystems to be affected by at least one anthropogenic driver (whether it is global or local). Some drivers, such as some pollutants (e.g. DDT) never existed in nature and others existed in much lower amounts or intensity (carbon dioxide or ammonia). Ecosystems are currently affected by drivers, which limit or impact biodiversity with different intensities. In this work, we use the term ‘Driver Intensity’ to convey not only the amount but also the toxicity of the drivers affecting biodiversity. Additionally, the driver’s intensity changes over time. In the past, biodiversity was mostly affected by air pollution (e.g. sulphur dioxide and metals), while nowadays nitrogen pollution is the driver with stronger effects on biodiversity, particularly in rural areas. In the future, we expect changes in climate patterns due to climate change to become the most important driver. Sulphur dioxide in the atmosphere increased almost ten-fold during the industrial revolution (with its maximum in the '70s), whereas ammonia emissions increased more recently and with an intensity of approximately four-fold. Climate change effects on biodiversity are mostly related to changes in the deviation from average climatic variables, such as the case of global surface temperature. Due to this, significant changes were only recently detected, and its intensity is still low in comparison with the magnitude of the previous drivers. In the Era of Anthropocene and under the framework of the Essential Biodiversity Variables, the main aim of this work is to call attention for the need to develop Biodiversity Change Indicators and Surrogates to monitor biodiversity changes. These can only be interpreted and applied after knowing their relationship with the drivers that limit or impact biodiversity. Our conceptual model will be based on the selection of the most cost-effective biodiversity change metric having in mind the nature and intensity of drivers, and the nature of the Essential Biodiversity Variables.

A ULisboa promove o Dia Aberto M23, um evento que pretende aproximar o público adulto do meio universitário.

In this course, we promote a multidisciplinary approach presenting the most recent findings on the topic and challenging the traditional way of considering symbiotic associations as exceptions and not as the rule.

The goal of this course is to provide to the participants with current and practical knowledge on urban ecology, including ecological and social aspects.

Neste encontro, vamos descobrir as potencialidades da utilização do Jamboard - um quadro branco digital gratuito da Google - em trabalhos colaborativos.

Nesta formação, aprenderemos a criar apresentações dentro do Mentimeter, a criar diferentes tipos de slides e a selecionar as configurações mais adequadas aos objetivos pedagógicos.

Nesta formação, iremos abordar as diferentes etapas do processo de planificação de unidades curriculares e refletir conjuntamente em boas práticas sustentadas pela investigação.

This course aims to explore ways of communicating science to non-specialized audiences, such as policy makers, industry, general public (including students and teachers), through their engagement and participation in citizen science activities.

O evento pretende juntar técnicos, investigadores, estudantes, produtores, industriais e demais agentes da fileira, contribuindo para a atualização de dados sobre o setor e a partilha de conhecimentos sobre as potencialidades da flora portuguesa, para além, das condições edafoclimáticas nacionais que potenciam produtos de elevada qualidade.

This course introduces the field of island biogeography, a discipline that has long influenced other research areas such as macroecology, community ecology, evolution and conservation biology.

Scientists, as the main actors in the production of scientific knowledge, have the responsibility of having an active voice in communicating this knowledge – and that can be achieved for example by a conscious use of the communication tools at their disposal and a better articulation with journalists, among other means.

This course aims at providing students with basic knowledge of R programming, allowing them to manipulate and visualize data with R.

This course aims at providing students with statistical knowledge and tools to manipulate, analyze and visualize biological data with R. It also includes an introduction to modeling, simulations and Bayesian statistics.

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.

The course provides essential skills and knowledge that enable the participants to develop climate change adaptation strategies.

The objective of this course is to provide participants with basic knowledge on a) the fundamental aspects of experimental design and b) workflows, platforms and tools to increase reproducibility at all scientific levels.

This is a mostly practical course offering an overview on different community ecology and macroecological methods and software. These will include all steps of a research project, from the optimal sampling of communities to process inference from large-scale patterns of taxon, phylogenetic and functional diversity.

This course aims to walk through the grounds of modern botany studies, covering subjects that have been excluded from most academic curricula.

The course aims at enabling the participants to use different methods to measure the impacts of pollutants on ecosystems. Basic knowledge will be provided through theoretical and practical lessons on how to select and use the most suitable metrics based on the analysis of multiple compartments of the ecosystems.

This course offers an overview of the different ways to measure biodiversity, and provides tips for the stratification of primary biodiversity data and the construction of variables that describe its various facets. It also includes an in-depth review of the different types of data used to measure biodiversity and their problems and limitations.
