Opis:: Patagoński hemul (Hippocamelus bisulcus) należy do rodziny jeleniowatych (Cervidae) i jest klasyfikowany jako gatunek zagrożony wyginięciem. Obecna jego populacja wynosi 350-500 w Argentynie i 1.000 sztuk w Chile i jest skupiona w ponad 100 grupach rodzinnych. Ze względu na postępujący spadek liczebności konieczne jest utworzenie centrum hodowlanego, gdzie poza rozmnażaniem hemuli i ich wypuszczaniem do natury, będą prowadzone badania naukowe nad biologią tego słabo poznanego gatunku. Posiadanie zwierząt wychowanych na butelce pozwoli na pobieranie nasienia przy użyciu sztucznej pochwy i na utworzenie banku genów, nasienia zamrożonego w ciekłym azocie (LN2).
Patagonian hemul (Hippocamelus bisulcus) is a member of the deer family (Cervidae) classified as an endangered species. The size of its population, estimated at 350-500 heads in Argentina and at 1000 in Chile, is distributed in over 100 family groups. Taking into account the gradually decreasing number of specimens, it is necessary to establish a captive breeding center. Besides reproduction and reintroduction to the natural environment, the center will help also to conduct scientific investigations on this poorly known species. Tamed animals reared on the bottle will allow to collect semen using artificial vagina, and would provide an opportunity to establish a live semen bank protected in liquid nitrogen (LN2), as a reserve of genes.

Opis:: Over the past half-century, an expansion of agriculture on lands is observed, followed with increased intensification through larger fields of monoculture crops and application of high level of inputs, that icreases the pressures agriculture sets upon the environment. Raising awareness of consumers and environmentalists led to the promotion of several alternative farming practices, including integrated food and non-food systems (IFNS). Here we explore the potential of different kinds of IFNS systems in delivering environmental benefits, focusing on preserving soil functions as the form of land use limiting the loos of soil by water erosion. Six successfully implemented IFNS systems located in UK, Poland, Italy, Denmark and Romania, were taken as a baseline to investigate their potential impact onto lowering soil loss by water erosion in their respective NUTS3 regions, when they would be applied widely on a regional scale. The results of analyses performed within GIS systems based upon European datasets revealed, that altogether the highest potential of limiting the area of soil erosion exceeding 0,5 Mg ha-1y-1 by an IFNS existing in a particular NUTS is observed in Romania, where 531km2 may be protected effectively with exiting silvopastoral system, while applied in a longer term on non-pastoral land cover classes it could provide effective protection for another 1362 km2. Second largest influence can be achieved in Polish NUTS region, where 125 km2 may be taken into protection directly and an another 1140 km2 may be transformed into agroforestry systems to lower the risk of soil erosion by water. In all investigated regions, a wide introduction of IFNS, that are already proven to be economically successful, would decrease soil loss considerably on existing land cover classes similar to IFNS systems covering 4927km2, while potentially on all agricultural land up to 8854km2.
