20 species of obligate parasitic phytotrophic Erysiphales and Pucciniales fungi had been found in the reserved natural boundary «Kishevo» (Baltskyi region, Odessa oblast). These species parasitized on 29 species of host plants of 24 genera and 14 families. This is the first report of species composition of powdery mildew and rust fungi in this boundary

In the paper given the results of landscape zoning of the territory of a water-collecting area of Kudma river– the right inflow of the Volga River. The researched territory lies within two landscape zones – forest and forest-steppe, two landscape provinces, four landscape areas. As a result of carrying out research 17 landscapes are allocated and characterized, the map of landscape structure of the territory of the basin of the river of Kudma is developed.

This article considers the question of the territories of the Roman cities of Arles (Arelate) and Avignon (Avennio) in the context of the changes brought about by the Roman penetration into south Gaul. Following recent work in geography on the different meanings of the term "territory", the author explains the importance of the difference between a catchment territory, defined by economic relations, and a political territory, defined by administrative dependence on a centre. Questions about territory and legal status must be asked independently of one another. The author follows A. Chastagnol in his view that Caesar granted autonomy to Marseille's former dependencies. It follows that Aries' territory, as it was known in the second century C.E., was formed by the aggregation, under the Imperial power, of politically heterogeneous territorial units. He emphasizes the importance of Avignon, which is the least known among the Roman towns of Rhone valley, and discusses the historical importance of the idea that the Rhone represented a natural boundary. In the geographical and political context of Gallia Narbonensis, there is no reason to be surprised that Glanum was an autonomous city possessing its own territory. Its coalescence with Arles or Avignon was the consequence of a territorial organization of the province in a later period. After its administrative assignment to one of these two chief towns, Glanum still had a territory attached to it., Cet article replace la question des territoires des cités romaines d'Arles et d'Avignon à l'intérieur des mutations qu 'entraîne la pénétration romaine en Gaule du sud. Prenant en compte l'évolution récente de la réflexion des géographes sur le territoire et la polysémie du terme, il insiste sur la différence entre le territoire « vivrier », défini par des données économiques, et le territoire politique, espace dépendant administrativement d'un centre. Les questions de territoire et de statut juridique doivent être posées indépendamment l'une de l'autre. Il s'appuie sur des propositions formulées par A. Chastagnol selon lequel César aurait accordé leur autonomie aux anciennes dépendances de Marseille. Dans cette perspective, le territoire d'Arles, tel qu 'on le connaît au second siècle, résulte d'une agrégation par le pouvoir romain d'unités territoriales politiquement hétérogènes. Il insiste sur l'importance dAvignon, qui est la grande méconnue des villes romaines du Rhône, et discute le rôle historique de limite « naturelle » attribué au Rhône. Dans ce contexte géographique et politique de la Gaule Narbonnaise, il n'y a pas lieu de s'étonner que Glanum ait été une cité autonome dotée d'un territoire. Sa réunion avec Arles ou Avignon correspondrait à une phase ultérieure de l'organisation territoriale de la province. À la suite de son rattachement administratif à l'un de ces deux chefs-lieux de cité, Glanum continue de disposer d'un territoire., Leveau Philippe.

Seven segments of tourist-recreational activity are considered in the article, tourist-recreational resources are analysed on territory of Zadnetroviya within certain types of landscapes, and also the complex estimation of these resources is conducted based on landscape diversity., В статье рассмотрены семь сегментов туристско-рекреационной деятельности. Проанализированы туристско-рекреационные ресурсы на территории Одеського Заднестровья в пределах отдельных видов ландшафтов, а также проведена комплексная оценка данных ресурсов на основе ландшафтного разнообразия. Впервые выделены ключевые ландшафтные (географические) участки с различным ландшафтным разнообразием., У статті розглянуто сім сегментів туристсько-рекреаційної діяльності, проаналізовані туристсько-рекреаційні ресурси на території Задністров’я в межах окремих видів ландшафтів, а також проведена комплексна оцінка даних ресурсів на основі ландшафтного різноманіття.

We present results and background rationale in support of a Polya--Carlson dichotomy between rationality and a natural boundary for the analytic behaviour of dynamical zeta functions of compact group automorphisms.

We present and exploit an analogy between lack of absolutely continuous spectrum for Schrödinger operators and natural boundaries for power series. Among our new results are generalizations of Hecke's example and natural boundary examples for random power series where independence is not assumed.

We classify singularities of Dirichlet series having Euler products which are rational functions for p and p^{-s} for p a prime number and give examples of natural boundaries from zeta functions of groups and height zeta functions.

We study the behaviour of the dynamical zeta function and the orbit Dirichlet series for products of maps. The behaviour under products of the radius of convergence for the zeta function, and the abscissa of convergence for the orbit Dirichlet series, are discussed. The orbit Dirichlet series of the cartesian cube of a map with one orbit of each length is shown to have a natural boundary.

We prove some conditions on the existence of natural boundaries of Dirichlet series. We show that generically the presumed boundary is the natural one. We also give an application of natural boundaries in determining asymptotic results.

This article explores embodiment and spatiality by discussing the example of a conflict between competing representations of landscapes and the female body in the two volumes of the comic books La Frontière Invisible (Schuiten & Peeters 2002 & 2004). This piece of fiction deals specifically and explicitly with a reassessment of the gaze in the production of knowledge by examining maps as tools of power, control and colonisation. However, despite an apparent desire to reject reactionary political approaches, the authors seem to associate the naturalised (female) body with (naturalised) geopolitical scenarios by fetishising the body through complex discursive transcodings between women and nature. In contrast to this, this paper suggests considering the body as a site and space of resistance to (political) imposition. Drawing on both feminist geography and critical geopolitics, it suggests an alternative way of considering the consequences of embodied geographies for cartography by examining the links between naturalised bodies and naturalised political boundaries. The main argument is that the body, by posing an uncontrollable, unpredictable threat to regular ways of producing cartographic knowledge entails the possibility of a counterstrategic reinscription of spatial discourses and the creation of an alternative, more ethical cartography. This ethical cartography is rooted in embodied recalcitrance to imposed inscriptions associated with hegemonic positions.

Grand-llet, a white isolât on the Upper Reunion Island ? The concept of isolât which has been defined only by genetics and hastely taken up by other sciences, is applied at Grand-llet, in the area of the Cirque of Salazie on Reunion Island. The study of natural and socio-cultural boundaries allows us to apprehend the particular features of this population rather than conclude on its isolation., Le concept d'isolat (uniquement défini par la génétique et repris hâtivement par d'autres sciences) est appliqué à Grand-Ilet, secteur du cirque de Salazie à la Réunion. L'étude des frontières naturelles et socio-culturelles permet de saisir l'originalité de cette population plus qu'elle n'autorise à conclure à son isolement., Dion Michelle. Grand-Ilet, un isolat blanc des hauts de la Réunion ?. In: Espace, populations, sociétés, 1984-1. Limites et frontières. pp. 17-24.

If the sequence of coefficients of a random power series has a degenerate tail field, then either its circle of convergence is a natural boundary, or this situation can be achieved by subtracting a fixed series. This generalises the known result for independent coefficient sequences.

article en révision; The main result of this paper describe the meromorphic continuationof of a class of Bateman-like totien zeta function associated to a specialclass of arithmetical multiplicative functions, discovering a comb-like form ofthe region of meromorphic continuation, and we verify the expected naturalboundary by clustering logarithmic type singularities. A standard applicationof the Selberg-Delange classical method allows then us to derive in additionthe distribution of values of a class of multivariate multiplicative functions.
