Abstract:

The ARMOREC project has as the general aim the optimizing the capitalization of the Arnica montana L. natural populations from the north of the Eastern Carpathians by developing a new innovative model for the sustainable production of raw material (collecting, cultivation, conditioning) and of some eco-efficient processing methods of the vegetal material.

In this respect, it is necessary to develop inter- and transdisciplinary studies in the fields of biology, ecology, geomorphology, biotechnology and phytochemistry, grouped in 3 major components: the environment componen with connex aspects, the phytochemical and economical component – the capitalization by the industrial partner (SME).

The members of the concortium, by their expertise and experience in the project domain has the competences necesary to the development of the researches with a high degree of complexity and interdisciplinarity.

To attain the general objective of the project, we will process a series of activities grouped in 5 work packages corresponding the specific objectives:

1. Evaluating the bioproductive potential in the natural populations of A. montana from the north of thr Eastern Carpathians, on the basis of the quantitative and qualitative determinations onthe biomass yield, as well as the content of biologically active principles.

2. Evaluating the preservation status of the A. montana species in the target area, correlated to the main pressure factots.

3. Elaboration of a model of developing a coplimentary source of raw material by conventional and biotechnological methods.

4. The development of some eco-efficient methods of extraction and phytochemical anaysis for the main biologically avtive compounds – sequiterpen-lactons, flavonoids and phenolic acids, essential oil.

5. The development of an experimental model for the sustainable capitalization of A. montana (natural populations and experimenta cultures) by obtaining and characvterizing the specific phytocomplexes with multiple uses.

The originality of the project resides both in selecting the study and analysis methods and in the holistic approach of the problem that aim the whole capiatlizing chain of the principles of sustainable growth. It is the first time when an interdisciplinary approached is proposed to model the effect of the abiotic fators on the distribution of A.montana on the basis of a spacial analysis model.

Reaching the aims will promote the sustainable capitalization of the species in the north of the Eastern Carpathians, that will have complex , interdisciplinary stadie at the basis (with economic and scientific importance) and will generate added value over the whole chain of capitalization and will also assure the biodiversity conservation.

Although for A. montana he interst kept itsel at a high international level, in România, the species is slightly capitalized, both economically and scientifically. Thus, thorough studies are scrace, integrated in the present state of the species in the natural populations, in the preservation and capitalizing and promoting of autochthonous products. The majority of the studies achieved in Romania refer to the Apuseni Mountains, in the Eastern Carpathians, the species being only mentioned in some floristic studies.

By developing this project, we aim the sustainable capitalization of the species at local and regional level, in relation to the peculiarities of the species, and of its status as a rare and vulnerable species and the demands of the market.

Approaching a species that has already for long been studied worldwide, represents a reason to elaborate a capitalization plan of the species, this being in the same time a very good model to capitalize other medicinal, aromatic and food species of the mountain zone. In the time, this model of sustainable capitalization may be adapted and extrapolated to all the Romanian areals of this species.

CLIMATE VARIABILITY RECORDED BY GLACIAL DEPOSITS AND LAKE SEDIMENTS Call name: Projects for Young Research Teams - TE-2012 call

Abstract:

The goal of the project is to synthesize data from glaciolacustrine records (laminated/varved lake sediments) and glacial deposits from surrounding areas that span the Last Termination (ca 22–11.5 ka) and Holocene for climate reconstruction. We propose the investigation of three key regions (glacial lakes within classical glacial cirques from three corners of the Romanian Carpathians - Maramures, Iezer and Retezat) for understanding the pattern of glaciation(s)/deglaciation(s) and Holocene climatic events in the Carpathians in the context of rapid climate variability. The project will provide new data relevant for palaeoclimate evolution at regional scale and the high-resolution sedimentological and chronological data employed will allow signal calibration and comparative analysis of different proxies and time-series. Our multi-proxy approach is intended to i) overcome limitations of palaeoclimatic and dating methods; ii) combine different climatic signals into a composite profile; and iii) carry out palaeoclimatic reconstructions taking into account regional and global climatic profiles and identify regional constraints of rapid climate oscillations. The project is not intended to be a singular effort in investigating palaeoclimate evolution in the Romanian Carpathians, and should be regarded as the framework for further investigations of the hitherto neglected Carpathian-Lower Danube region-Balkan Mts. due to its multidisciplinary approach.

Reconstruction of Romanian river channel changes in the last 11,700 years: the role climatical conditions and of human impact Call name: Exploratory Research Projects - PCE-2011 call

Abstract:

The project is set out to get involved in the debate which animated the most recent comments of the scientific community in the field of Earth Sciences, namely: how sensitive are certain forms and processes on the surface of Terra (in the current case, rivers and their beds) to the natural or induced by human activities control factors and which is the size of these changes along a period of time sufficiently long (about 11,700 years). The questions we wish to answer are:(1)Which are the fluvial styles and rates of changes in the study area, during the entire Holocene?(2)Which are the control factors (both natural and anthropic ones) responsible for the spatial and temporal behavior of the fluvial systems and how important are they? Has the human control became more important than the climatic one, starting with Middle Holocene?(3)How is placed the behavior of Romanian rivers in the European context?(4)What scenarios can be developed regarding river channels evolution in the subsequent period of time? Time threshold of 150 years BP was chosen (given by the oldest precise cartographic documents in Romania).Research methods:(1)instrumental measurements, the bed material sedimentology, river channel planforms and drainage basins characteristics using GIS platform;(2)floodplain sediment analysis through geophysical methods,topographic surveys, 150-200 absolute datings (14C and OSL) of organic and inorganic material.Study area:Somes,Siret and Prut rivers.
