The basis for preserving ecological balance and rational use of natural landscapes is the formation of a system of protected areas and objects. In the Ukrainian Carpathians, on the large areas naturally develop radical forests (virgin forests), the habitats of the bear, wolf, and many rare species of plants are preserved. Thus, the natural ecosystems of the Ukrainian Carpathians in the Nature Reserve Fund of Ukraine are the most represented. The consequence of increasingly global anthropogenic influence became a global phenomenon of fragmentation (decomposition) of the natural landscapes. One of relatively preserved natural variety is the areas of the national park “Verkhovynskyi”. The National Park “Verkhovynskyi” is a very important centre of the natural and cultural diversity of Ukraine. The main representative of the flora in the region is spruce common. Shrubberies on the territory of the Chyvchyn Mountains are represented by thickets of mountain pine. The biological value of the territory of the NP “Verkhovynskyi” is largely determined by the uniqueness of the high-altitude spruce forests. In the park, the animal world is rich and varied. Its biological uniqueness of its territory is largely determined by local landscape diversity. The landscape structure of the park area is the result of long-term interaction of the main landscape-factor factors: geological-geomorphological, hydro-climatic and biotic. The leading role belongs to the geological and geomorphological properties of the territory, which determine the climatic characteristics, the regime of humidification, distribution of biota and soil cover. The dominant position in the structure of landscapes is the high-altitude terrain of the steep-sloping erosion-denudation forest middle mountains. In contact with the Peneplainized highlands, the area has an island distribution in the form of mid-mountain spurs of the main ridge. Characteristic are tracts of convex crests of spurs, saddles and steep slopes. The historical and cultural value of the NP “Verkhovynskyi” district is based on the rich events of the history of the region. The territory of Verkhovyna district is the heart of Hutsulshchyna, and its centre is the village Verkhovyna. The successful operation of the NP “Verkhovynskyi” will be a major impetus for the tourist development of the Verkhovyna district. The orientation of the national natural park for the development of recreational activities will increase the number of tourists, will create additional demand for accommodation and food services that will be provided by the local population. Development of the tourism infrastructure of the park will give an impetus to the restoration and full functioning of the former and the creation of new settlements. Particular attention should be paid to laying the network of roads and tourist routes and their improvement. The scientific value of the territory of the NP “Verkhovynskyi” is high, which lies in the unique ability to study local natural ecosystems that are very close to natural or reference. The article analyzes in detail the natural peculiarity of the national park, and, to the extent possible volume of the article – unusually rich landscape and recreational resources (in particular, humanistic, historical, cultural, etc.) of its territory.

Adequate information on agricultural land suitability for viticulture are important for the expansion of the activity in wine producing regions, as the state of Santa Catarina, Brazil. This information contributes to improve the efficiency of evaluations, with the inclusion of different management levels for the crop and redefinition of limiting levels of agricultural land conditions. In this context, the objective of this work was to adapt the Land Agricultural Suitability Evaluation System (LASES) to grapevine crops grown in high-altitude regions in Santa Catarina. The LASES was modified based on the crop demands and managements, proposing the incorporation, removal, adjust and update of parameters used in the LASES. The limiting factors considered were topography, fertility, water excess or oxygen deficiency, susceptibility to erosion, impediments to meccanization, and soil effective depth. These traits were based on data of bibliographic surveys and five limiting levels were attributed to them: null, mild, moderate, strong, and very strong. Agricultural suitability classes like good, regular, restrictive and inapt resulted from the interaction between agricultural conditions and management levels of viticulture producers, and later, a suitability guide table was developed. The adaptation of the LASES to grapevine crops grown in high-altitude conditions in Santa Catarina incorporate and adjust local aspects that are important for the grapevine production system. Thus, it is an important tool for decision making when implementing new vineyards and contributes to a possible increase of this activity in the region.

Information on the biodiversity of high altitude lakes in the Stelvio National Park was scarce and fragmentary, in most cases limited to a few studies on a single biological issue. To fill this gap, a multidisciplinary research program was established in 2011 to investigate macroinvertebrates, diatoms, and water chemistry in 8 high altitude lakes within the boundaries of the Park (Rhaetian Alps, Eastern Alps). The results of this study were compared with data on biological assemblages and chemical parameters of Alpine lakes in the Pennine-Lepontine Alps (Western Alps), to evaluate the role of local drivers with respect to regional ones. This comparison was possible thanks to the adoption of standardized sampling methodologies developed since the ’90s by the National Research Council-Water Research Institute (Verbania), in collaboration with several European Research centers. Despite located in a restricted geographical area, the lakes of the Stelvio National Park showed a high variability of chemical composition, and of sensitivity to acidification, lower than that of the Pennine-Lepontine Alpine lakes. Macroinvertebrate and diatom taxa were ubiquitous and frequent along the Alps, and mainly represented by cold-stenothermal species. Richness, Shannon, Simpson, and Pielou indices applied to phyto- and zoobenthos highlighted significantly lower values in Stelvio National Park lakes than in those of Pennine-Lepontine for macroinvertebrates, while no significant differences were found for diatoms. Two groups of lakes were identified by Cluster Analysis, mainly on the basis of major ion concentrations. Canonical Correspondence Analysis showed that the macroinvertebrate assemblage of the lakes studied is driven mainly by altitude and lake surface, and, to a lesser extent, by nutrient content. On the contrary, pH and acid-related variables played a secondary role for diatoms, while nutrients and, more in general, ionic content had significant effects on their species composition. Overall, the results of this first investigation showed that the high elevation of these lakes affects their macroinvertebrate assemblages, while their diatom communities are comparable throughout the Alps.

We investigated the relationship between the number of growth rings (a surrogate for approximate age of stems) and basal girth for Eucalyptus pauciflora (Maiden & Blakely) L.A.S.Johnson & Blaxell. Using basal-girth measurements and growth-ring counts obtained from trees felled on ski slopes at three Victorian alpine ski resorts, as well as seedlings destructively sampled from near the tree line on four summits, we modelled the relationship between growth rings and basal girth by using simple linear and non-linear regression methods. We compared our data to growth-ring–basal-girth data collected from low- and high-altitude E. pauciflora woodland stands in Kosciuszko National Park. The relationship between the number of tree rings and basal girth at Victorian sites was non-linear (growth rings = 3.62 × girth0.63, R2 = 0.96). In general, the Victorian and Kosciuszko datasets were in broad agreement, although caution is required when attempting to estimate the age of trees with >115-cm girth. We suggest that the model we have developed can be combined with dendrological techniques to estimate the age of older trees accurately.

Dioscorea sphaeroidea is endemic to the high-altitude grasslands of the Serra dos Órgãos National Park located in southeastern Brazil. Based on the spheroid shape of its fruit and seed, i.e., not flattened or winged, this new species is morphologically unusual in the Dioscorea genus. Moreover, its unique morphology leaves this new species with no clear position in the infrageneric taxonomy of Dioscorea. Herein we present the morphological description of this species, including a discussion of its ecology and habitat, distribution, and preliminary risk of extinction assessment.
