Research interests
Statement of research interests
My backgrounds as a forest engineer and my growing passion for ecology have guided me to the fields of dendrochronology and dendroecology. The current highlight of my research is the use of tree rings for understanding the relationships between “plant/tree and environment” and its application to the study of (environmental) change.
In the long term, I hope to contribute to ecological research by exploiting novel tree-ring information and innovative dendrochronological applications. Example case studies performed in a (Swiss) ecologically variable alpine context should contribute to the visibility of the research. Essentially I am interested in all topics that contribute to understanding the processes of storing information in tree-rings. Among those topics, the identification of tree responses to a changing environment in the wood and the interpretation of their ecophysiological meaning (tree functioning) are especially relevant. My field of activity is therefore prevalently anchored in dendroecology, but strongly interacts with other disciplines such as tree physiology, wood anatomy and plant ecology. And finally, the acquired knowledge should be applicable to the study of global change (from land use to environment and climate change).
Currently and for the next two to five years, I plan on focusing my work on two promising ongoing research areas. On the one hand, I aim to further evaluate the potentiality of wood cell anatomy as an ecological indicator. The research activities focus in particular on the identification and evaluation of environmental signals encoded in wood cell anatomical features of both hard- and softwood species, on improving the methodological basis for an efficient and reliable survey, on testing their application for both improving the ecophysiological understanding of tree functioning, and for using them as ecological proxies to reconstruct the past and provide a better scenario for the future. On the other hand, I intend to develop the use of tree rings to predict changes in forest composition and structure in a changing environment. Research will concentrate on the analyses of tree-ring relevant modifications in growth or competitive responses along time and space. The acquired knowledge should contribute to evaluating the effect that a changing environment will have on future forest development.
My work is goal-oriented. As far as is possible, I split broad research questions into modular projects, which answer specific questions while contributing to the understanding of the whole. I try to set up studies with efficient design and straightforward statistics. Results are published in international scientific journals but also presented at conferences and when relevant, disseminated for the praxis. Synergic collaborations are welcome. Fundraising will increase the working capacity as well as promote young expertise that can further develop and disseminate ideas and applications.<br/><br/>

Publications
- Fonti, P., and ~ 50 coauthors (in prep). XCELL — a repository for dated xylem cell anatomy and density profile data.
XCELL is an initiative promoting the creation and maintenance of a central repository of wood cell anatomy and intra-annual density profile data. Background
The structure of the wooden cells is important for the functioning and performance of trees as it play a main role in transporting water and solutes and provides the necessary mechanical support and storage for long-term survival. <br/>
These properties, combined to the fact that these cells are immutable and calendrically datable (via dendrochronological methods), have been early recognized to be keys to retrospectively understand how the environment at sub-annual scale can affect the wood characteristics and the functioning of trees. <br/>
Despite this potential, due to difficulties in quantifying the anatomical characteristics on a large number of cells, the measurement of cell anatomical features along series of dated tree rings (so-called tree-ring anatomy) has been little applied. Nowadays, thanks to important improvements with tailored image analysis software (e.g.; Roxas) and affordable sample preparation (e.g.; Microtomes), the survey, although still with important investment in time and money, is becoming more accessible. <br/>
With this initiative we aim at valuing these and future large measuring efforts by collecting, assembling, and harmonizing the data. We hope so to provide a service for the community to address new and broader research questions. <br/>
Aims of the initiative to preserve and promote individual efforts in quantifying cell anatomical and intra-annual density profile measurements performed along dated series of tree-rings to define standards and good praxis for the measurement and analyses of cell anatomical data to assemble, harmonize and facilitate the distribution/exchange of worldwide measured and dated datasets of xylem cell anatomical and intra-annual density data to make use of the data to complement or infer novel insights in the mechanism of xylem formation and functioning, as well as for assessing their impact on the plant-environment interaction and related biogeochemical cycles. Expected output Assemblage and harmonization of cell anatomical and density profile measurements from around the world Publication(s) on large-scale intra- to inter- seasonal wood anatomical responses Requirements
Cell anatomy or density profile data submitted to the XCELL must meet certain requirements before assimilation into the holdings. The collection is structured in order to only include cell anatomical or wood density profile data that are spatial-, chrono-, and geo-referenced, i.e.; only localized intra-ring measurements that have been obtained from dated annual rings (possibly along series of tree-rings), and from plants material collected from known locations. Consequently, a dataset usually includes data file (see examples from Roxas output) with the measurements of wood anatomical features (see a description for tracheid and vessels survey) as characterized from a wood cross-section and is accompanied by metadata (see the template) describing the characteristics of survey (e.g. site and trees characteristics and measuring procedure applied). For contributions, please consult the Guidelines for data intellectual property and publications (pdf) and the Instruction for data submission (pdf).
Current holdings of the collection
XCELL is an initiative that requires a long-term perspective to fully exploit its promises. Currently, the collection contains cell anatomical measurements of tree-rings from the stem wood of only mature conifer trees (only tracheids). This collection contains measurements from 38 sites (Fig. 2).
Fig. 2. Climatic space coverage of the collected conifer datasets. The mean annual temperature and mean annual precipitation of the sites are superposed on the Earth’s biomes definition according to Whittaker (1975). The biomes are Tundra (TU), Taiga (TA), Temperate grassland desert (TG), Woodland shrub-land (WS), Temperate deciduous forest (TD), Temperate rain forest (TE), Subtropical desert (SD), Tropical forest savanna (TS), Tropical rain forest (TR). Red site label = harmonized data; blue site label = data not yet collected or harmonized. Site information is given here.
