An eight-hectare forest reserve in the centre of the metropolitan area in SE Poland was investigated for the effects of its management in relation to its purpose—protection of old Quercus robur L. trees. This local issue corresponds to a wider debate on the role of urban forests in contemporary societies. The study embraced (1) oak stand history—stand mapping and dendrochronology, historical maps’ analysis; (2) vegetation trends—undergrowth and ground layer analysis; and (3) visitors’ opinions on the reserve’s use—interview. The dendroecological analysis corroborates the landscape’s history emerging from the 1700s–1900s maps. The reserve is a feral park established in the early 1900s on the abandoned agricultural, partly wooded landscape. Under the current regime, shade-tolerant trees continue gaining advantage over older oaks, preventing their regeneration, whilst the herb layer, due to the reserve’s isolation remains poor and polluted by alien species. The non-intervention approach does not allow the reserve’s objective to be met. We recommend the restoration of features of semi-open silvopastoral landscape. This would correspond with both local eco-history and the dominating preference of the interviewed visitors. Such “bio-cultural refugia” should become key knowledge centres of the natural, cultural, and economic importance of the “working rural landscape”, fostering urban care for the countryside.

Abstract:This article focuses on the mechanisation of agriculture in central Italy in the thirty years or so after 1945. This provides a particular way of examining the major changes in the rural landscape in this period, especially the end of the sharecropping system. Land in these regions had for centuries been predominantly farmed under sharecropping contracts, but for political, economic, and demographic reasons this system, which had inhibited modernisation, entered a rapid decline. Whereas labour supply had previously exceeded demand, the reverse became the case, allowing sharecropping families more freedom in how they operated. Mechanisation was not a ‘push’ factor, but as the agricultural labour force contracted it was a necessary response. The article uses individual testimony to illustrate how tenant farmers started to work outside the sharecropping contract, some becoming outside contractors with other farms and supplying tractor hire. The mechanisation of agriculture was slow and uneven, but marked an irreversible change in the relationship between farming families and their land.

ABSTRACTOne of the world's great Victorian-era suburban metropolises, Melbourne, Australia, was transformed by mass immigration and the redevelopment of some of its older suburbs with low-rise flats and apartments in the post-war years. Drawing on a range of sources, including census material, municipal rate and valuation books, immigration and company records, as well as building industry publications, this article charts demographic and morphological change across the Melbourne metropolitan area and in two particular suburbs in the mid- to late twentieth century. In doing so, it both responds to McManus and Ethington's recent call for more histories of suburbs in transition, and seeks to embed the role of immigration and immigrants into Melbourne's urban historiography.

AbstractOcean striations are composed of alternating quasi-zonal band-like flows; this kind of organized structure of currents be found in all world’s oceans and seas. Previous studies have mainly been focused on the mechanisms of their generation and propagation. This study uses the spatial high-pass filtering to obtain the three-dimensional structure of ocean striations in the North Pacific in both the z-coordinate and σ-coordinate based on 10-yr averaged SODA3 data. First, we identify an ideal-fluid potential density domain where the striations are undisturbed by the surface forcing and boundary effects. Second, using the isopycnal layer analysis, we show that on isopycnal surfaces the orientations of striations nearly follow the potential vorticity (PV) contours, while in the meridional-vertical plane the central positions of striations are generally aligned with the latitude of zero gradient of the relative PV. Our analysis provides a simple dynamical interpretation and better understanding for the role of ocean striations.
