Oral Lectures 32 POLLINATION ECOLOGY PROVIDES SOME NEW INSIGHT INTO EVOLUTION AND SYSTEMATICS OF MEDITERRANEAN LEGUMES Giovanni CRISTOFOLINI, Marta GALLONI, Licia PODDA, Daniele VIVARELLI Herbarium and Botanical Garden, University of Bologna, Italy. giovann.cristofolini@unibo.it A great diversity of Leguminosae–Faboideae is found in the Mediterranean region, including many endemic and rare taxa. Among tribes having their main diversity centre in the Mediterranean area, let’s mention Loteae, Coronilleae, Vicieae, Cytiseae, the last being the richest in species. It is well known that tribes and genera have been historically established on morphological grounds, with special regard to floral characters. Recent taxonomic revisions, mainly based upon molecular characters, have challenged the traditional taxonomic treatment, as several genera that used to be regarded as natural ones, turned out to be polyphyletic. The inconsistency between "traditional" (morphological) taxonomy and phylogenetic (molecular) relationships is a major point of concern in pursuing a natural system of classification. The question arises, whether the incongruence between natural groups based on morphological traits and monophyla based on molecular homology is due to experimental flaws or has a biological foundation. Pollinators’ ethology, form and size play a relevant role in shaping floral structures, and more so when pollination is specialized. Most Legumes have been reported in the past to be "generalist", i.e. pollinated by several different insect taxa. However, the very concept of generalist vs. specialist species needs to be critically examined: a species pollinated by several insect taxa may be specialized, as far as its fitness is enhanced by only one or few of them, or by a structurally homogeneous insect guild, when other pollinators exert little influence on seed production, or even depress it. In this light, recent evidence has shown that pollination in Mediterranean Legumes may be much more specialized than previously reported. Such "cryptic" specialization may account for homoplasy of floral characteristics, so the species that share important floral features, and hence are regarded as forming "natural" genera, may be the outcome of common pollination strategy rather than represent monophyletic clades. Keywords: Faboideae, homoplasy, phylogeny, pollination specialization, taxonomy. 20
RECENT INNOVATIONS BROUGHT BY GEOGRAPHIC INFORMATION SYSTEMS AND REMOTE SENSING IN VEGETATION AND FLORA STUDIES IN TURKEY Hakan Mete DO�AN 1 , Musa DO�AN 2 , Ferhat CELEP 2 1 Gaziosmanpasa University, Agricultural Faculty, Soil Science Department, Tokat hmdogan@hotmail.com 2 Department of Biological Sciences, Middle East Technical University, Ankara, doganm@metu.edu.tr fcelep@metu.edu.tr In the last two decades, the use of geographic information systems (GIS) and Remote Sensing (RS) increased rapidly due to the great interest of many institutions in Turkey. Parallel to this increase, hardware, software and trained people structures started to develop. This progress enabled the preparation of some countrywide digital databases to be used in spatial analysis and modelling processes. Flora and vegetation studies took the benefit of these improvements, and some applications showed the emerging utility of these tools. In this presentation, we summarized two latest innovations of us that can be used for plant bio-diversity and community composition mapping. In the former, we explained how plant bio-diversity of Nall�han forest ecosystem were modelled and mapped in GIS by utilizing diversity indices (Shannon Wiener, Simpson, Number of Species), environmental variables (soil, topography, geology and climate), and remotely sensed data (LANDSAT-ETM+). In the latter, we summarized the ways of Normalized Difference Vegetation Index (NDVI) usage to develop plant community composition maps of Tersakan Valley in Amasya by using both GIS and RS. Keywords: Geographic information systems, remote sensing, plant bio-diversity, community composition, mapping 21 33 Oral Lectures
