My main research interest is to understand the distribution of life on earth (e.g. species, biodiversity, vegetation types, ecosystems) through space and time. I am particularly interested in interactions between climate and the terrestrial biosphere. This includes potential impacts of climate change on species, ecosystems and associated ecosystem services, as well as the role of the biosphere in the earth climate system (e.g. carbon and water cycling). Methodologically, vegetation and ecosystem modelling at local to global scales has been at the core of my work.

Examples of current research projects:

– GEOEssential
– EarthShape: Earth Shaping by Biota 
– Ecosystem Management Support for Climate Change in Southern Africa (EMSAfrica)
– The open Climate Impacts Encyclopedia (ISIpedia)
– Developing dynamic regional to global vegetation models
–  Accounting for habitat characteristics and biotic interactions in biodiversity models
– Modelling the role of fire in the functioning of the terrestrial biosphere
– Effects of plant trait variability on ecosystem stability and resilience
– Assessing the impacts of climate change on biodiversity and ecosystem Services
– Causes and ecosystem impacts of megafauna extinctions
– Impacts of climate change and air pollution on mountain ecosystems in Scandinavia, France and Spain

Examples of environmental impact assessments:

– Intergovermental Platform on Biodiversity and Ecosystem Services (IPBES), ongoing
Policy support tools and methodologies for scenario analysis and modelling of biodiversity and ecosystem services 
– North Sea Region Climate Change Assessment (NOSCCA, chapter Terrestrial Ecosystems)

Research interests

My work is focused on understanding the dynamics of tropical forests, its natural spatial and temporal patterns, and its response to anthropogenic pressures. In order to embrace its complexity, I use forest modelling and remote sensing as tools for tropical forest research, ultimately aiming for future applications in order to halt biodiversity loss in a future with strong human tropical presence.

I have a Bachelor’s degree in Environmental Sciences (2006), Master’s degree in plant ecology (2009) in Pernambuco Federal University and PhD (2017) in Ecological Modelling from the University of Osnabrück. I have experience in the field of ecology, with emphasis in forest ecology; ecological modelling, with focus on forest dynamics of fragmented landscapes and geographical information systems, climate change with focus on the carbon and hydrology cycles.

Keywords

Forest modelling, Animal-plant interactions, Forest fragmentation, Remote sensing, Carbon and hydrological cycles

CURRENT PROJECTS

  • Environmental changes in biodiversity hotspot ecosystems of South Ecuador: RESPonse and feedback effECTs (RESPECT)

 

RESPECT aims to unveil how major ecosystem functions, (i) ecosystem biomass production, and (ii) water fluxes, are affected by ongoing and future environmental changes through alterations in response and effect traits of relevant biota for the mountain rain forest in South Ecuador. This question is addressed through the synergy of field and modelling studies, for which I carry out the development. The model also seeks to address questions of climate change and anthropogenic nutrient deposition in tropical mountain forests to ecosystem function and biodiversity loss along an elevational gradient. 

The model in development for this project is the LPJ-GUESS-HUMBOLDT model, which includes implementation for the topics:

  • Trait diversity

As opposed to the plant functional type approach, in which few representative species are simulated, the use of dynamic traits allows the plant community to adapt through ecological filtering to local simulated conditions. This allows for more adaptive simulations in which functional biodiversity can be represented and its value tested.

  • Carbon, Nitrogen, Phosphorus soil-vegetation dynamics

The role of soil organic matter dynamics in vegetation structure and composition has been a hot topic in recent years due to their limiting effect on plant productivity during climate change scenarios. The implementation of these nutrient dynamics will also permit a better understanding of e.g. temperature increase and soil carbon storage, and the effects of increased human nutrient deposition.

  • Biotic interactions

LPJ-GUESS-HUMBOLDT also includes the representation of biotic interactions in its development, which have a significant effect on vegetation communities. The model will include both herbivory and seed-dispersal processes which are long known in empirical studies to affect several aspects of community composition and nutrient cycling.

  • Coupling with hydrological and atmospheric models

In addition to the development of novel modules, coupling with an atmospheric and a hydrological model is on course, which will allow for the exchange of variables. From the model`s perspective, this represents a whole new level of complexity because it allows driving data which was previously fixed to be influenced by model outputs.

RESEARCH INTERESTS

The main focuses of my research are vegetation and ecosystem processes and the role of vegetation in the Earth system. To study these topics, I use process-based models (primarily the Dynamic Global Vegetation Model LPJ-GUESS) applied to spatial scales ranging from regional to global and temporal scales ranging from millions of years ago to the next century.  I am particularly interested in the effects and feedbacks of fire in the Earth system.

 

CURRENT PROJECTS

Fire in the Earth System – I am working to improve the process-based representation of wildfire (in particular the SPITFIRE model) in vegetation models.  Fire is key in shaping the functioning and structure of large areas of the terrestrial land surface and is responsible for large carbon dioxide and other trace gas fluxes. As part of this work I am a coordinator of the Fire Model Intercomparison Project (FireMIP, website to be moved from KIT to Senckenberg soon)

 

Coupling LPJ-GUESS to an Atmospheric Chemistry enabled GCM – I am also working on a combined modelling framework which couplies LPJ-GUESS to the EMAC atmospheric chemistry model utilizing the MESSy interface.  This work will enable the investigation of many atmosphere-biosphere interactions and feedback including tracing gas emissions from vegetation and fire, changing vegetation structure and function, tropospheric ozone damage to plants, and Nitrogen fertilization and emissions.

RESEARCH INTERESTS

I am a quantitative ecologist specialized in freshwater ecology, with some years spent in marine science and terrestrial botany. In my research, I love to break down complex patterns into understandable chunks, which could be generalized to understand the overall complexity. Throughout my career, I worked on the interaction between humans and nature and currently focus on how humans drive biodiversity change by introducing new species, so-called neobiota. I strive to understand the introduction and establishment of neobiota over large spatial scales and how this has changed in the past and will change in the future. The spread and establishment of neobiota are tightly coupled to human activity, and as a consequence it is necessary to first understand changes in human activity related to neobiota such as trade, transport, and human migration over large spatial and temporal scales. Much of my research therefore deals with the analysis of human activity to predict the spread and the establishment of neobiota.

RESEARCH INTERESTS

My main interests involve the response and feedback of the carbon cycle in the land vegetation to climate change, with a special focus on boreal and temperate forest   ecosystems. I am particularly interested if increases in plant respiration and forest   mortality due to rising temperatures and more frequent and severe climate extremes may outweigh gross productivity increases in the future.  To address these research questions, the monitoring of vegetation characteristics and dynamics therein by remote sensing technologies will be of vital importance. I am using remote sensing-based information on the spatial distribution of forest carbon stocks (biomass) in synergy with field data in order to evaluate, calibrate and improve global vegetation models.

 

CURRENT PROJECTS

I am working towards identifying the drivers of changes in tree carbon use efficiency (CUE) in boreal and temperate forests. This work will be the basis for approaches to increase CUE to enhance wood productivity and carbon stocks under future climatic conditions. As a first step, I am currently collecting available measurements of tissue nitrogen concentrations in stems, roots, and leaves of common boreal and temperate tree species.

RESEARCH INTERESTS

For my Ph. D. project, I am simulating population dynamics of large herbivores in the Late Pleistocene. Working with extinct megafauna species requires a strictly bottom-up approach: scaling up from physiological mechanisms to populations. The megafauna model is coupled with the dynamic global vegetation model LPJ-GUESS into a process-based representation of the long-extinct Mammoth Steppe. Complex models of ecosystems that have no modern analogue are subject to high uncertainty. My approach is therefore to make use of uncertainty for pointing towards new and concrete research directions. Having academic training in both ecology and computer science, I place a strong emphasis on high-quality software engineering, reproducibility, and Open Science best practices.

RESEARCH INTERESTS

My main research interest is to understand how ecosystems around the world change due to global change, including natural and anthropogenic factors. I am interested in changes in land cover and land use, vegetation composition and diversity, carbon storage, fire regimes, and their interactions and impacts on climate, as well as the consequences thereof and their influence on society. Modelling and understanding global fire occurrence have been my main research interests over the last years. Fire is an important agent of ecosystem change in many regions but also poses major risks for society, including the direct loss of property and lives, poor air quality, and changes ecosystem structure and functioning, e.g. it reduces the forest cover and vegetation carbon storage. Models are an important tool in summarizing our current understanding and they offer the possibility to be one step ahead of what can be measured. Because of this, I believe that vegetation models will become increasingly important to support decision making in ecosystem management. Many of the processes included in vegetation models are not yet well understood or not well constrained. I therefore use approaches that let me integrate information from observations with process-based model simulations. The methods I apply range from model evaluation with simple descriptive statistics to machine learning algorithms and hybrid modelling. My goal with these data analyses is to understand how models can and need to be improved and to develop an understanding of the uncertainty in both models and observations.

RESEARCH INTERESTS

My research interests involve the field of climate-vegetation interactions and human influences. This matches well with the BMBF-funded SPACES project EMSAfrica (Ecosystem Management Support for Climate Change in Southern Africa). EMSAfrica focuses on the effects of natural disturbances, such as the impacts of land-use and climate change on the structure and functioning of South African terrestrial ecosystems. It also focuses on the production of information relevant to ecosystem management in the region.  Within the scope of this project I am working with the dynamic vegetation models (DVMs) aDGVM and aDGVM2 with a focus on Southern African vegetation changes. By using DVMs, I would like to detect changes in ecosystems and identify areas that require special attention in ecosystem management. Thus, I can contribute to protecting and maintaining biodiversity in vulnerable ecosystems.
