Abstract Habitat use and preferences by raptors were studied during three non-breeding seasons (2011-201 3) in an agricultural landscape in western Slovakia. The non-breeding season on agricultural land showed high variation and changes in the cover of habitats related to human activities. The most abundant raptor species were the common buzzard Buteo buteo (L.) (1 52 individuals) and the common kestrel Falco tinnunculus (L.) (78 individuals). The common buzzard preferred alfalfa and avoided ploughed fields. The common kestrel showed a high habitat preference for alfalfa, corn fields, stubbles and fallow. It also avoided ploughed fields and wheat.

AbstractThe aim of this paper is to describe agricultural landscapes in the cadastral area of Hriňova and their development in the context of social and economic changes over the past 60 years. This area is characterized by the occurrence of historical structures of agricultural landscape (HSAL) which are important because they comprise various cultural, environmental and ecological aspects. The assessment of land use changes on the two scales of cadastral area and selected small localities highlights that the most important trend here is agricultural extensification. The results show that despite these changes in land use, the historical structures in the agricultural landscape represented by forms of anthropogenic relief remain a permanent part of this research area.

The 1960S

SUMMARYRed-legged partridge (Alectoris rufa) populations have significantly declined in the Iberian Peninsula (by > 50% between 1973 and 2002). This decline has been attributed to the drastic changes that have occurred in traditional agricultural landscapes, among other factors. This paper assesses the relationship between landscape change and the changes in areas favourable to partridges. The areas favourable to partridges in Andalusia (southern Spain), and the environmental and land-use factors that determined these areas, were identified for both the 1960s and the 1990s. Land-use changes were analysed both throughout the study area and for areas where favourability for partridges has either improved or worsened during recent decades. Both the location and the factors determining areas favourable to red-legged partridges have changed substantially over recent decades. In the 1960s, areas favourable to partridges were associated mainly with natural vegetation in mountainous areas, whereas, by the 1990s, favourable areas were associated with large low-lying croplands; such change may be attributable to regional land-use changes. The percentage area of the main natural vegetation variables positively correlated to partridge favourability in the 1960s model (mainly pastures and open scrubland) had decreased in areas that had become unfavourable to the species (such as mountain areas), and risen where partridge favourability increased. By the 1990s, the land area favourable to partridges had decreased by c. 10% (c. 6000 km2) in southern Spain, whereas land use unfavourable to partridges markedly increased (> 100%; an increase of c. 3000 km2). Landscape suitable for partridges has thus become severely impoverished over recent decades in the Iberian Peninsula. Management measures aimed at improving the landscape for farmland birds should be encouraged to conserve red-legged partridge populations in southern Spain.

SummaryLocal changes in land use can influence patterns of habitat selection by farmland birds, thus biasing predictions of population responses to land use changes based on wildlife-habitat or niche modelling. This study, based in arable farmland in south-central Spain, determined whether habitat selection (use of agricultural habitats and the distance to roads, tracks and buildings) by Great Bustards Otis tarda varied between two nearby areas with differing land uses. The western sector has experienced a process of land abandonment and infrastructure development linked to an airport project that started in 1998 and finished in 2009, while the eastern sector maintains extensive dry farmland systems. Great Bustards avoided ploughed fields and selected short- and long-term fallows. Selection of fallows was more intensive in the sector suffering recent land-use changes, where these substrates were more abundant. Great Bustards were distributed further from roads, paths and buildings than would be expected if individual birds selected habitats at random. Avoidance of infrastructure was strongest in the area suffering recent land-use changes. Local patterns of habitat selection seemed to change in relation to agricultural abandonment and infrastructure development. Consequently, conservation measures based on knowledge of broad patterns of habitat use and selection such as agri-environmental schemes may fail to ensure steppe bird conservation locally if such local effects are overlooked. Specifically, schemes should include landscape-scale restrictions on the development and use of infrastructure (roads, tracks and buildings). Analyses of the patterns and causes of local and regional changes in habitat selection are essential to conserve populations of endangered farmland birds.

<p>Gullies are traditionally considered as one of the most active landforms in agricultural areas. In many places gully erosion leads to massive loss of fertile soil, decline of areas available for cultivation and a number of other land use complications. In addition, gullies in many cases act as the most effective runoff and sediment routing pathways, promoting better connectivity and increasing sediment delivery from cultivated hillslopes into fluvial network. Hence, gully network development may also cause significant detrimental off-site effects, including small river degradation, reservoir siltation, particle-bound pollutants concentration, etc. On the other hand, this process is often not progressive and unidirectional, but rather includes cycles of incision and head retreat alternating with infill periods. Understanding this dynamics and knowing its control factors may help to predict the future process trends for different climate and land use change scenarios, save fragile soil and water resources and design sustainable agricultural activity in changing environment.</p><p>We analyzed five different small river basins in Central European Russia to investigate the cycles of gully growth and infill. The main approach was to acquire gully network structure from topographic maps or by manual visual interpretation of satellite images. A set of topographic maps was used to map the spatial structure of gullies over the case study areas for several time intervals from mid XIX century to the end of XX century. In addition, recent satellite images were used to investigate the up-to-date (2018-2019) gully network structure and distinguish its possible latest changes related to climate or land use changes.</p><p>It is common to consider agriculture as the main factor of gully erosion activation in this area. We found that land use changes over the last 150 years lead not only to erosion rates shifts, but to incision and infill cycles. Besides, morphometric parameters of individual gullies, spatial patterns of gully network and gully density within different catchments strongly depend on local topography. Particularly important controls are topographic ranges, long profile and planform shapes of catchment slopes. Recent studies also showed that planform structure of upper parts of gully network (especially small tributary gullies of larger gully systems), as well as smooth slope depressions and periodically formed ephemeral gullies on cultivated hillslopes are in many cases strongly related to relic cryogenic features (RCF) of the Late Pleistocene cold stages. Evidence of partly infilled gullies incised into the RCFs such as ice or ice-ground wedge pseudomorphs are widely observed both on satellite and airborne images and in natural (undercut gully or small valley banks) or anthropogenic (quarries) exposures.</p><p>Interaction of climatic impact, intrinsic gully headcut retreat threshold and recent land use changes determine modern gully network conditions. The main presently observed tendency is stabilization or gradual infill of most of the small- and medium-sized gullies by sediments transported by sheet wash, rill and ephemeral gully erosion from arable fields. At the same time, small discontinuous bottom gullies are developed in larger gully systems.</p><p>This study is supported by the Russian Foundation for Basic Research (Project No. 18-05-01118a).</p>

Vines and olives are two important and widespread traditional agricultural crops that are also connected to the Judeo–Christian–Muslim tradition. The goal of the research was to demonstrate the importance of using cartographical sources to obtain a more accurate and complete view of the past. To this end, the aims were: (1) to reconstruct the former agricultural land-use in three periods, 1873–1874, 1917, and 1943–1945; (2) to analyze the different spatial physical factors that could explain the spatial distribution of traditional agricultural landscapes; (3) to identify the changes which took place between the three reconstructed timestamps. The research employed different cartographic sources and the implemented analyses were conducted using GIS tools and methods. The results show that, in the past, the distribution of vines and olive groves greatly depended on several physical geographic factors (climate, slopes, direction). Nonetheless, human factors such as political instability, cultural and religious beliefs contributed as well. Moreover, this research showed how GIS has advanced historical geography research. Lastly, the research demonstrated that obtaining the most complete view of the past can be achieved by a combination of sources together with the use of GIS tools and methods.

Zusammenfassung Gegenstand und Ziel: Aufgefundene Wildgreifvögel sollten nur nach medizinischer Diagnosestellung, entsprechender Therapie und anschließender Vorbereitung auf die Wildbahn ausgewildert werden. Hierfür sind je nach Greifvogelart und Alter der Tiere unterschiedliche Trainingsmethoden, inklusive falknerischer Methoden notwendig. Nach Abschluss dieser Maßnahmen und Auswilderung wurden Greifvögel mittels Telemetrie überwacht, um die Überlebensfähigkeit und die Prognose von Erkrankungen/Verletzungen für die Wildbahnfähigkeit einschätzen zu können. Zusätzlich sollte die Telemetrie als Überwachungsverfahren evaluiert werden. Dies fand in Kooperation mit Schülern statt, um einen Betrag zur Naturerziehung zu leisten. Material und Methoden: Drei Mäusebussarde (Buteo buteo) und ein Turmfalke (Falco tinnunculus) wurden fallspezifisch in der Klinik behandelt und nach Abschluss der Therapie mit einem an einer Schwanzfeder befestigten Sender entlassen und täglich per PKW oder Flugzeug verfolgt. Nach Peilung der Tiere erfolgte eine Sichtung mittels Fernglas. Die GPS-Daten der Aufenthaltsorte der Vögel wurden notiert. Ergebnisse: Ein Tier verlor den Sender frühzeitig, sodass keine Verfolgung möglich war. Die anderen drei Vögel wurden über mehr als 14 Tage überwacht. Ihre gute Reintegration in die Wildpopulation ließ sich durch beobachtetes Balz-und Paarungsverhalten belegen. Die weiteste Flugstrecke eines Vogels betrug 44 km. Schlussfolgerungen: Tiermedizinische Maßnahmen mit dem Ziel der Wiederherstellung der Wildbahnfähigkeit von Wildvögeln können erfolgreich sein. Die Telemetrie eignet sich zur Überwachung ausgewilderter Vögel. Die Handhabung der Technik ist problemlos durch Laien (z. B. Schüler) durchführbar. Klinische Relevanz: Übereinstimmend mit anderen Studien bestärken die Daten Tierärzte in der ordnungsgemäßen Durchführung von Rehabilitationsmaßnahmen an aufgefundenen Wildgreifvögeln.
