THANKS!

The TRACE 2015 conference was held on 20-23 May 2015 in Sevilla, Spain. This was the first TRACE in the Iberian Peninsula. It was organized by the University Pablo de Olavide (UPO) and the Association for Tree-ring Research (ATR), in collaboration with Pyrenean Institute of Ecology-Spanish National Research Council (IPE-CSIC), University of Barcelona (UB), Forest and Wood Technology Research Centre (CETEMAS) and University of Valladolid (UVa). TRACE 2015 seeks to strengthen the network and scientific exchange of scientists and students involved in the study of tree-rings. It aims to present and discuss novel research and approaches in tree-ring science. The scope of the meeting included all fields of dendrochronology and its application on archaeology, climatology, geomorphology, glaciology, fire history, forest dynamics, ecology, plant anatomy, hydrology and physiology, including the use of stable isotopes. It was a pleasure for all the people involved in the organization to share interesting, enriching and lovely week in TRACE 2015. Thanks for this unforgettable week!. TRACE was a meeting with so many young scientists, students and experts coming from whole Europe and some of them from Asia, Africa and America (>130). We hope you enjoyed the courses, venue, Spanish food, breaks, Icebreak, talks, events (Guided tour in Sevilla, Flamenco show, Special dinner), scientific program, experiences and field trip!. For us it was a wonderful experience. On behalf of the Organization, we warmly thank you for your participation and collaboration in this TRACE in Sevilla (Spain). See you soon in future dendro-meeting (hopefully ;-)) Good luck with your dendro-life!! Thank you to all for your participation in TRACE 2015 All the best The organizers and other members of the Scientific Committees, 2015

Field trip (optional) Abies pinsapo forests

FIELD VISIT (23 May 2015) Abies pinsapo forests Declared the first Biosphere Reserve (MaB) by UNESCO in Spain (1977), Sierra de Grazalema Natural Park located in the north east of the province of Cádiz and in the north west of Málaga, at an altitude ranging from 250 to 1,654 metres above sea level. Grazalema natural park covers 53,411 hectares and it is one of the areas of greatest ecological importance in the South of the Peninsula, and therefore of great significance in Spain as a whole. It is a special protection area for birds. It has the highest rainfall in the Iberian Peninsula, with an annual average of over 2,000 mm (it has the historical maximum precipitation in Spain of 4334 mm in 1963), and is the most important western massif of the Subbetica range. Its heavy rainfall and limestone terrain have created a limestone landscape rich in slopes, grottoes, caves and winding gorges.

Besides the dense Mediterranean forest of holm oak, cork trees, pines and others species, the Park’s most emblematic element is the Spanish fir (Abies pinsapo Boiss.), mainly concentrated in the Sierra del Pinar Mountains. It is in the central part of the Natural Park, between the towns of Benamahoma, Grazalema and Zahara de la Sierra. It is an important forest of Spanish firs (pinsapo), considered a relict species of the tertiary period (Linares et al. 2011). This species is a descendent of the central-European fir trees, which formed major forests here during the glacial periods. Nowadays, these Spanish fir trees can only be found here, in the Sierra de las Nieves Nature Park and in the Sierra Bermeja Mountains (both in Málaga province).

These pinsapo forests were severely damaged over the centuries through a variety of unsustainable practices such as overgrazing, logging and pollarding. Following the

conservation measures implemented and the progressive abandonment of traditional uses in the late 1950s, the fragmented populations expanded and the scattered remaining stands became denser, which provides a range of locations varying widely in their land-use history and forest canopy structure. It has been the centre of intense ecology and dendrochronological research (Plan Recuperación del Pinsapo, CoMo-ReAdapt, TRANSHABITAT and several projects) undertaken at the Junta de Andalucía, University Pablo de Olavide and University of Jaen over the past 15 years.Also, a lot of diverse institutions are working on different research lines focused on Abies pinsapo forests (Univ. Córdoba, Univ. Sevilla, Univ. Málaga, Univ. Politécnica Madrid, CSIC) more click the image

FIELD VISIT Human presence in the area dates back to the Palaeolithic period and today, one of the main objectives in its management is to strike a balance between human activity and the natural environment, a regional history really interesting for Dendrochronologist (scientifics in general). The Spanish fir forest and other areas in the Biosphere Reserve can only be visited at certain times of the year, and visitor numbers are limited. However, TRACE 2015 participants will have this unique opportunity to visit the southernmost Abies species in Europe.

Initial eco-development experiments and other development initiatives have been carried out here. Through these guided tour, we will introduce some of the fir ecology, climatic change effects, the influence of logging on the Spanish fir woodlands and their current recovery. The coordinator of Abies pinsapo conservation plan (José L. Quintanilla), the Director of the Natural Park (María Peña Mora), the forest managers and several expert researchers will show us about it.

Keywords: Defoliating insects, mountain pine beetle, forest pest distribution, forest disturbances

Development of models for predicting impacts of insect pests on forest resources requires estimates of future outbreak recurrence, expected levels of tree mortality and growth loss caused by the insect. These estimates are usually based on historical accounts and dendrochronological reconstructions of past outbreak occurrence and assume that future pest incidence will resemble the past. Examination of existing infestation maps, based on the short survey records available (records exist only since the 1950‟s), and comparison with current pest distribution (Alfaro et al., 2009), indicate that a possible range expansion may be in progress for mountain pine beetle in Alberta and for spruce budworm in British Columbia (Alfaro et al., 2014). We report results of research to establish the long term history of these two pests and discuss the opportunities offered by dendrochronology for the study of historic forest insect distributions, as well as the limitations of the methodology (Axelson et al., 2015).

Silver fir (Abies alba) has been suffering from SO2-polluted air over many decades in the past. New data from Thuringia, East Germany, close to the Northern border of natural distribution, are presented. While the absolute minimum of ring widths occurred around 1980 (Elling et al., 2009), a sudden additional increase after 1990 could be observed. This is explained by the fact that recovery partially started after reducing the emissions in (West-) Germany, but that the industrial restructuring in East Germany after 1990 strongly enhanced the effect. During the depression between 1960 and 1990 high elevation sites showed a stronger modulation by climatic factors compared to lower elevations. Since 1990 total annual increments were much higher than before the depression, possibly attributed to increased nitrogen deposition. Absolute ring widths were higher at cooler submontane sites which are closer to optimal conditions of a mixed beech-fir forest. However, the performance of trees at summer-warm and dry sites was better than expected. The response to extreme (drought) years, especially 2003, 2006 and 2011, was also investigated in comparison to Norway spruce (Picea abies). In general, silver fir seems to be more resistant than spruce showing a relatively smaller decline in dry years (cf. Zang et al., 2014). This makes silver fir a promising candidate to (partially) replace Norway spruce under the expected global warming in the future. The potential to grow on drier sites and to buffer dry years underlines this conclusion. References Elling, W. et al. 2009.

Mediterranean plants have developed various structural and ecophysiological mechanisms to face drought stress. With the aim to study different strategies of coexisting species, we evaluated intrinsic water use efficiency (WUEi), the ratio of photosynthesis (A) to stomatal conductance (gs), of two broad-leaved evergreen (Pistacia lentiscus and Phillyrea angustifolia) and one needle-like-leaved evergreen (Juniperus phoenicea), growing in the Capo Caccia area of Sardinia (Italy). The WUEi was assessed using tree-rings 13C, while 18 O was useful to understand the control of stomatal conductance influence. Mean WUEi of J. phoenicea resulted significantly higher (133.7 ± 5.5 mol mol-1, p
