Corsica in Autumn
Corsica in Autumn Naturetrek Tour Report 25 September - 2 October 2016 Report compiled by David Tattersfield Naturetrek Mingledown Barn Wolf's Lane Chawton Alton Hampshire GU34 3HJ UK T: +44 (0)1962 733051 E: [email protected] W: www.naturetrek.co.uk Tour Report Corsica in Autumn Tour participants: David Tattersfield and Jason Mitchell (leaders) with 10 Naturetrek clients Day 1 Sunday 25th September We arrived at Calvi airport at 1.00pm. It was sunny and hot, with a temperature of 28°C. We drove first into Calvi, to allow a brief exploration of the town and to buy provisions for our lunches. The first butterfly we saw was a Geranium Bronze, on some Pelargoniums, a new record for us, in Corsica. We travelled south, through the maquis-covered hills, crossed the dried-up Fango river and stopped by the rocky coastline, just north of Galeria, for lunch. Plants of interest, in the vicinity, included the yellow-flowered Stink Aster Dittrichia viscosa, the familiar Curry Plant Helichrysum italicum, and a robust glaucous-leaved spurge Euphorbia pithyusa subsp. pithyusa. On the rocks, by the shore, were two of the islands rare endemics, the pink Corsican Stork’s-bill Erodium corsicum and the intricately-branched sea lavender Limonium corsicum. Our first lizard was the endemic Tyrrhenian Wall Lizard, the commonest species on the island. We headed south, on the narrow winding road, stopping next at the Col de Palmarella, to enjoy the views over the Golfe de Girolata and the rugged headland of Scandola. Just before reaching Porto, we entered some very dramatic scenery of red granite cliffs and made another stop, to have a closer look at the plants and enjoy the view. -

Responses of Riparian Guilds to Flow Alterations in a Mediterranean Stream
Responses of riparian guilds to flow alterations in a Mediterranean stream Maria Dolores Bejarano, Marta González del Tánago, Diego García de Jalón, Miguel Marchámalo, Alvaro Sordo-Ward & Joaquín Solana-Gutiérrez Keywords Abstract Composition; Diversity; Establishment patterns; Mature forest; Pioneers; Shrubland; Questions: Do Mediterranean riparian guilds show distinct responses to stream Stream water declines water declines? If observed, which are the most sensitive and resilient guilds and their most affected attributes? Nomenclature López González (2001) Location: Tiétar river below the Rosarito dam, central-western Spain. Methods: We identified riparian guilds based on key woody species features and species distribution within this Mediterranean river corridor, and evalu ated similarity of their responses to long-term flow alteration (i.e. stream water declines since dam construction in 1959). Hierarchical cluster analysis was used to group surveyed vegetation bands according to species composi Bejarano, M.D. (corresponding author, tion.

1.0 Introduction
1.0 Introduction Fats and oils are very important in the human diet due to the high content of essential fatty acids, which are necessary for the appropriate development of human tissues (Moya Moreno et al., 1999). Many studies were conducted to study the utilization of wild plants as a source of unconventional oils and their maximum utilities as antioxidants chronologically (Mirghani et al., 1996; Mirghani, 1990; Mariod, 2000). Inexpensive sources of protein that can be incorporated to value-added food products are in demand all over the world and most of the research is directed to various sources of proteins (Chandi and Sogi, 2007; Rangel et al., 2003 ; Sogi and Bawa, 2002) that may help in increasing the nutritional value of the products. Plants have for a long time been a veritable source of drugs; man tends to ignore the importance of herbal medicine (Nair and Chanda, 2007). Scientists worldwide care about the scientific exploration of medicinal plants for the benefit of human beings. Many African plants are used in traditional medicine as antimicrobial agents but only few were documented (Bellomaria and Kacou, 1995; Lewis and Elvin-Lewis, 1997; Ahmad et al., 1998). In view of the fact that antimicrobials are sometimes associated with adverse side effects e.g. hypersensitivity, immunosuppressive and allergic reactions, it is therefore of interest to develop alternative antimicrobial drugs such as medicinal plants for the treatment of infectious diseases (Clark, 1996). 1 A number of potential phytoantimicrobial agents, such as phenolic compounds have been isolated from olives and virgin olive oil, and among these are polyphenols and glycosides, these phytoantimicrobial agents incorporating nutraceutical advantage while enhancing food safety and preservation (Keceli et al., 1998). -
Oral Presentations
ORAL PRESENTATIONS Listed in programme order Technical analysis of archaeological Andean painted textiles Rebecca Summerour1*, Jennifer Giaccai2, Keats Webb3, Chika Mori2, Nicole Little3 1National Museum of the American Indian, Smithsonian Institution (NMAI) 2Freer Gallery of Art and Arthur M. Sackler Gallery, Smithsonian Institution (FSG) 3Museum Conservation Institute, Smithsonian Institution (MCI) 1*[email protected] This project investigates materials and manufacturing techniques used to create twenty-one archaeological painted Andean textiles in the collection of the National Museum of the American Indian, Smithsonian Institution (NMAI). The textiles are attributed to Peru but have minimal provenience. Research and consultations with Andean textile scholars helped identify the cultural attributions for most of the textiles as Chancay and Chimu Capac or Ancón. Characterization of the colorants in these textiles is revealing previously undocumented materials and artistic processes used by ancient Andean textile artists. The project is conducted as part of an Andrew W. Mellon Postgraduate Fellowship in Textile Conservation at the NMAI. The textiles in the study are plain-woven cotton fabrics with colorants applied to one side. The colorants, which include pinks, reds, oranges, browns, blues, and black, appear to be paints that were applied in a paste form, distinguishing them from immersion dyes. The paints are embedded in the fibers on one side of the fabrics and most appear matte, suggesting they contain minimal or no binder. Some of the brown colors, most prominent as outlines in the Chancay-style fragments, appear thick and shiny in some areas. It is possible that these lines are a resist material used to prevent colorants from bleeding into adjacent design elements. -

Edita: Conselleria de Medi Ambient Direcció General de Biodiversitat Dibuix de la coberta: Joan Miquel Bennàssar Impressió: Gràfiques Son Espanyolet Diposit Legal: PM 1992-2002 Pròleg Aquesta obra que teniu a les mans és el producte d’un llarg procés de recerca i d’investiga- ció. És el resultat de més de 12 anys de treballs que han duit a terme els científics del grup s‘Albufera-IBG i molts d‘altres experts i aficionats que han aportat l’esforç i els coneixe- ments per completar aquesta visió global de la biodiversitat de s‘Albufera de Mallorca. Un cos de coneixements que s’ha anat formant pas a pas, com és característic de tot procés cien- tífic. La Conselleria de Medi Ambient és ben conscient que la conservació del patrimoni natural no es pot fer sense els estudis que ens han de permetre conèixer quins són els recursos sota la nostra responsabilitat i quin valor tenen. De cada vegada el gran públic coneix més quines són les espècies amenaçades i les accions per conservar-les troben ressò en els mitjans de comunicació i en la sensibilitat de la socie- tat en general. Però cal demanar-se: estam fent tot allò que és necessari per garantir la con- servació del patrimoni natural per a les generacions pròximes? Són suficients els coneixe- ments actuals d’aquest patrimoni? Quines espècies o quines poblacions són les més valuo- ses? Aquest llibre ajudarà a respondre algunes d‘aquestes preguntes. És un compromís entre la visió del científic, que sempre desitja aprofundir en l’estudi, i els gestors, que demanen amb urgència unes eines adequades per planificar les accions de conservació i avaluar-les. -

F9.3 Mediterranean Riparian Scrub
European Red List of Habitats - Heathland Habitat Group F9.3 Mediterranean riparian scrub Summary This riparian scrub is an azonal habitat of irregularly flooded environments in a warm Mediterranean climate, occurring mainly along the beds of uncontrolled rivers but also in relatively fresh or brackish coastal sites. Summer drought is long and severe and, even inland, salinisation is possible. The habitat is threatened by changes in the hydrology of rivers to maintain water supplies and also by pollution, afforestation, removal of shrubs for cultivation and intensive grazing and urbanisation. Synthesis The overall decrease in quantity is relatively low (-12%), resulting in the category Least Concern (LC). The quality shows a slight negative trend affecting on average 20% of the surface with a moderately high severity (49%). Also these values lead to the conclusion Least Concern. Overall Category & Criteria EU 28 EU 28+ Red List Category Red List Criteria Red List Category Red List Criteria Least Concern - Least Concern - Sub-habitat types that may require further examination The Mediterranean riparian scrub is defined to include some coastal scrub on the Black Sea shores. This subhabitat differs from the core of the habitat definition, which relates to Mediterranean alluvial scrub, and may be considered as a separate habitat for assessing the threatened status. It is possible (but not certain, because of data gaps) that the Black Sea shore type is more threatened than the Mediterranean type.

Most records are made on retaining walls and historical fortifications. 60,5 % of the plants are indigenous, 7,0 % are archaeophytes, 32,6 % are neophytes. Wooded species, at least 20 (23,3 %) play a more important role compared to Central Europe due to the climatically preferred area in the western Mediterranean. Some further species which may grow spontaneously in joints are pointed out, however clear evidence could not be found. Introduction During a guided excursion in early spring to important gardens at the Côte D’Azur it was possible to study the vascular plants flora of numerous walls. This cursory observation is not at all complete but they are helpful to close gaps in our research project on ‘Biodiversity of walls in Europe and neighbouring areas’. Nomenclature and floristic status follow as far as possible NOBLE et al. (2016). The family affiliation of the species complies with CHRISTENHUSZ, FAY & CHASE (2017).
