The river stretches for 270km in total and 70km are flowing within the Greek area. Downstream of the Pigai dam in Greece (10km from the springs of Aoos), the river is near natural, representing all types of river ecosystems, including canyon sections, braided parts and meandering stretches. In Greece the protected area, that partly includes river Aoos, belongs to the Northern Pindos National Park. The existing National Park is already protecting 50kms of Aoos’ river stretch, leaving nearly 20km of the river unprotected, towards the GR-AL borders (see Map 1). At the same time one of the major tributaries, Voidomatis (15km long) is included in the existing National Park, leaving 6km of the tributary unprotected, towards the GR-AL borders. Another major tributary, river Sarantaporos (50km long), stretches under no protection zone, from its springs until its confluence with Aoos, right upon the GR-AL borders. Voidomatis and Sarandaporos rivers are the main tributaries of Aoos. Voidomatis meets up with Aoos in the plain of Konitsa, and Sarandaporos joins them right on the Greek-Albanian border. Through this year’s biodiversity research, we aim to increase the biodiversity knowledge for the unprotected area of the Aoos river basin, in order to further support the efforts of the campaign for the expansion of the Aoos’ protected area towards the GR-AL borders, in a way that will include the unprotected stretches of Aoos and its major tributaries (Voidomatis, Sarantaporos). The present study is focusing on insect species related to water (Odonata), as well as on large mammals, either directly related to the riverine ecosystems (otter) or indirectly (carnivores and ungulates). The present biodiversity research sets four distinct objectives: • To provide a georeferenced database of species distribution in the study area, with special focus on the part of the area that is under no protection status. • To assess different microhabitats of Aoos’ catchment in terms of their ecological value for the target species. • To assess potential pressures and threats for the species. • To crystalize research findings into concrete conservation objectives.

Summary – After the third European Congress of Odonatology (ECOO) which took place from 11 to 17 July in Montpellier (France), 21 odonatologists from six countries participated in the week-long field trip that was organised in the Aude department. This area was chosen as it is under- surveyed and offered the participants the possibility to discover the Languedoc-Roussillon region and the dragonfly fauna of southern France. In summary, 43 sites were investigated involving 385 records and 45 dragonfly species. These records could be added to the regional database. No less than five species mentioned in the Habitats Directive ( Coenagrion mercuriale , Gomphus flavipes , G.

Gorb Department of Functional Morphology and Biomechanics, Institute of Zoology, Kiel University, Am Botanischen Garten 9, 24118 Kiel, Germany; [email protected] (E.Q.); [email protected] (S.N.G.) * Correspondence: [email protected] Received: 12 June 2020; Accepted: 25 June 2020; Published: 28 June 2020 Abstract: Leaf insects (Phasmatodea: Phylliidae) exhibit perfect crypsis imitating leaves. Although the special appearance of the eggs of the species Phyllium philippinicum, which imitate plant seeds, has received attention in different taxonomic studies, the attachment capability of the eggs remains rather anecdotical. Weherein elucidate the specialized attachment mechanism of the eggs of this species and provide the first experimental approach to systematically characterize the functional properties of their adhesion by using different microscopy techniques and attachment force measurements on substrates with differing degrees of roughness and surface chemistry, as well as repetitive attachment/detachment cycles while under the influence of water contact. We found that a combination of folded exochorionic structures (pinnae) and a film of adhesive secretion contribute to attachment, which both respond to water. Adhesion is initiated by the glue, which becomes fluid through hydration, enabling adaption to the surface profile. Hierarchically structured pinnae support the spreading of the glue and reinforcement of the film. This combination aids the egg’s surface in adapting to the surface roughness, yet the attachment strength is additionally influenced by the egg’s surface chemistry, favoring hydrophilic substrates.

Blloku “Vasil Shanto”, Tirana, Albania (Received October 1999, accepted May 2000) Abstract: The geothermic field in Sarandaporos-Konitsa lies in the cross-border area between Albania and Greece. The field has several surface manifestations and extended geological investigations, including tectonic and geomorphological studies have been carried out. This work presents the field application and interpretation of vertical electrical sounding (VES) data in both sides of the borders. The purpose was to study the structure down to the depth of 1000 m, in a relative large area, where information about the deep structure would have an extreme cost if acquired by a network of boreholes. Two main geoelectrical formations that coincide with the flysch and the limestone basement are revealed. The area appears faulted in the NW-SE and NE-SW directions and a few concealed graben and horst structures exist. Low resistivity values were observed above basement uplifts and major faults. These values were attributed to hot fluid circulation. Key words: Electrical Sounding, Geothermal Field, Sarandaporos-Konitsa Area, Albania, Greece. INTRODUCTION present study.

    Synoikism, Urbanization, and Empire in the Early Hellenistic Period by Ryan Anthony Boehm A dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy in Ancient History and Mediterranean Archaeology in the Graduate Division of the University of California, Berkeley Committee in charge: Professor Emily Mackil, Chair Professor Erich Gruen Professor Mark Griffith Spring 2011 Copyright © Ryan Anthony Boehm, 2011 ABSTRACT SYNOIKISM, URBANIZATION, AND EMPIRE IN THE EARLY HELLENISTIC PERIOD by Ryan Anthony Boehm Doctor of Philosophy in Ancient History and Mediterranean Archaeology University of California, Berkeley Professor Emily Mackil, Chair This dissertation, entitled “Synoikism, Urbanization, and Empire in the Early Hellenistic Period,” seeks to present a new approach to understanding the dynamic interaction between imperial powers and cities following the Macedonian conquest of Greece and Asia Minor. Rather than constructing a political narrative of the period, I focus on the role of reshaping urban centers and regional landscapes in the creation of empire in Greece and western Asia Minor. This period was marked by the rapid creation of new cities, major settlement and demographic shifts, and the reorganization, consolidation, or destruction of existing settlements and the urbanization of previously under- exploited regions. I analyze the complexities of this phenomenon across four frameworks: shifting settlement patterns, the regional and royal economy, civic religion, and the articulation of a new order in architectural and urban space. The introduction poses the central problem of the interrelationship between urbanization and imperial control and sets out the methodology of my dissertation. After briefly reviewing and critiquing previous approaches to this topic, which have focused mainly on creating catalogues, I point to the gains that can be made by shifting the focus to social and economic structures and asking more specific interpretive questions.

  • Struggles Against Dams and River Diversions in Northwestern Greece
    Struggles against dams and river diversions in Northwestern Greece (Sarajevo, 27-29/9/2018) Ioannis Papadimitriou Ioannina Ecological Organizations Net As one greek poet wrote “The rivers are the mailmen of the mountains”. So, in the beginning was Pindos mountain chain, which runs through continental Greece and shapes a climatic border between the more rainy western Greece and the rest of the country. Here are the springs of the longest greek rivers, flowing either to the east or to the west. 3 struggles against big dams or river diversions are the most interesting in the area, the first victorious in the past, the second continuing for many decades and the third necessary in the future. I shall describe in brief 2 of them, concerning Arachthos and Aoos rivers in Epirus Region and also Epirus Water Department (for Acheloos case, east of Pindos, there is another presentation). 1. Arachtos It originates in Pindos and flows to the south into Amvrakikos Golf. Since early 80’s there is the Pournari big dam in operation in its lower flow. The initial plans of the State Electrician Company was the transformation of Middle Arachthos in a system of successive hydroelectric dams. That’s why the water from Aoos springs dam was diverted to Arachthos after its use. The construction of the first planned, Agios Nikolaos dam, in the mountainous Tzoumerka area was announced in the mid-90’s, causing an 11 years struggle by local NGOs and societies, initially against the State Electrician Company and then against a private company. Finally the dam construction was cancelled by the Supreme Administrative Court (Decision 3858/2007 by Council of State).

Our results show that there are at least 31 species of fishes inhabiting the river system, of which 27 are native, including eight species endemic to the Balkans. With 11 species, Cyprinidae are by far the most specious family, followed by Mugilidae (five). Salmonidae and Acipenseridae are represented by 2 species each. The remaining ten families are represented by a single species. At least four species (Pseudorasbora parva, Oncorhynchus mykiss, Carassius sp., Gambusia holbrooki) were introduced into the Vjosa basin. The provided list includes the distribution of each species in River Vjosa, as well as annotations referring to in- troductions, taxonomic-and their conservation status.

Brown bear populations in Greece are confined to the mountain ranges of Pindos and Rodopi. Systematic data on brown bear spatial behavior based on telemetry data were lacking in Greece until 1997. This paper presents the results on brown bear habitat use patterns monitored on an annual basis in the area of Grammos and NW Voio mountains located in Northern Pindos range. A sample of six radiocollared brown bears (n=6, 5 males - 1 female) was monitored from 1997 to 2002 using ground telemetry. Generated data (n=3,052 bearings and n=739 radiolocations) were combined to an analysis of vegetation char- acteristics identified through a classification of eight habitat types according to vegetation struc- ture and dominant formations. Bear home range size varied individually from 102 km2 to 507 km2. Seasonal variability of home range size was also evident with fall presenting the highest values ranging from 87 km2 to 314 km2.
