Bioclimatic Modelling

Abstract The article describes the potential distribution area of B. bombina and fi gure out the signifi cant climatic factors of the species at a home range scale. Th is species is listed on Appendix II of the Bern Convention and on Annexes II and IV of the EU Natural Habitats Directive. It is protected by national legislation in many countries, occurs in many protected areas, and is listed in many national and sub-national Red Data books and lists. We collected the occurrence records and a set of climatic variables including 19 factors from 10’ resolution historical (summarizing annual trends, seasonality and extreme conditions during 1961-1990) and projected data (2050) available at the CliMond database. As a result, under climate predictions for 2050 there may be a substantial north and north-west shift of optimal habitat. Under such a scenario B. bombina populations may suff er mostly in the east and south of Ukraine. Under the modelled scenario the species representation in protected areas throughout the home range should be considered, but especially in Ukraine.

UDK: 597.551.2(497) Sabanejewia balcanica is a fish species that belongs to Cobitidae family and it is the endemic of the Balkan Peninsula. It is present in the tributaries of the Danube and Aegean waters. Systematics of this species has experienced certain changes that are related to the systemic instability of the entire Cobitidae family, so there has been a change in the name of the genus of this species. The genus Sabanejewia was separated from the genus Cobitis in the last century, but this name was generally used much later. According to data of the IUCN Red List of Threatened Species, this species is still not endangered, but is assigned a status of least concern (LC). Sabanejewia balcanica is in the Annex II of the Habitats Directive and Annex III of the Bern Convention which basically require the protection of this species and its habitats. In the proposal to create a red list of fauna of the Federation of Bosnia and Herzegovina, has been concluded that there is not enough information on the population characteristics of this species. The aim of this article is to present data on exploration of Sabanejewia balcanica in the Balkan area as well as Bosnia and Herzegovina, thereby contributing to the determination of its status of vulnerability and protection of its natural habitats.

The alpine lakes on the Tibetan Plateau (TP) are indicators of climate change. The assessment of lake dynamics on the TP is an important component of global climate change research. With a focus on lakes in the 33° N zone of the central TP, this study investigates the temporal evolution patterns of the lake areas of different types of lakes, i.e., non-glacier-fed endorheic lakes and non-glacier-fed exorheic lakes, during 1988–2017, and examines their relationship with changes in climatic factors. From 1988 to 2017, two endorheic lakes (Lake Yagenco and Lake Zhamcomaqiong) in the study area expanded significantly, i.e., by more than 50%. Over the same period, two exorheic lakes within the study area also exhibited spatio-temporal variability: Lake Gaeencuonama increased by 5.48%, and the change in Lake Zhamuco was not significant. The 2000s was a period of rapid expansion of both the closed lakes (endorheic lakes) and open lakes (exorheic lakes) in the study area. However, the endorheic lakes maintained the increase in lake area after the period of rapid expansion, while the exorheic lakes decreased after significant expansion. During 1988–2017, the annual mean temperature significantly increased at a rate of 0.04 °C/a, while the annual precipitation slightly increased at a rate of 2.23 mm/a. Furthermore, the annual precipitation significantly increased at a rate of 14.28 mm/a during 1995–2008. The results of this study demonstrate that the change in precipitation was responsible for the observed changes in the lake areas of the two exorheic lakes within the study area, while the changes in the lake areas of the two endorheic lakes were more sensitive to the annual mean temperature between 1988 and 2017. Given the importance of lakes to the TP, these are not trivial issues, and we now need accelerated research based on long-term and continuous remote sensing data.

In many parts of the world, freshwater crisis is largely due to increasing water consumption and pollution by rapidly growing population and aspirations for economic development, but, ascribed usually to the climate. However, limited understanding and knowledge gaps in the factors controlling climate and uncertainties in the climate models are unable to assess the probable impacts on water availability in tropical regions. In this context, review of ensemble models on δ18O and δD in rainfall and groundwater, 3H- and 14C- ages of groundwater and 14C- age of lakes sediments helped to reconstruct palaeoclimate and long-term recharge in the North-west India; and predict future groundwater challenge. The annual mean temperature trend indicates both warming/cooling in different parts of India in the past and during 1901–2010. Neither the GCMs (Global Climate Models) nor the observational record indicates any significant change/increase in temperature and rainfall over the last century, and climate change during the last 1200 yrs BP. In much of the North-West region, deep groundwater renewal occurred from past humid climate, and shallow groundwater renewal from limited modern recharge over the past decades. To make water management to be more responsive to climate change, the gaps in the science of climate change need to be bridged.

AbstractThe bush dog Speothos venaticus, a rare Near Threatened South American canid that lives in packs, was thought to be extinct in Minas Gerais state, south-eastern Brazil, until recently. Here, we report four recent records of the species in Minas Gerais, the first in the state since the description of the species in 1842. All records are from the Cerrado ecosystem in the north and north-west of the state; two are from animals found dead, one from footprints and another from a camera trap. Three of the records were inside or close (< 10 km) to strict protected areas, in a region recognized as the Protected Areas Mosaic Sertão Veredas–Peruaçu, where we expect any new records of the bush dog to be found. We discuss the low probability of detecting the bush dog and the main regional threats to the species, and emphasize the need to protect large and interconnected natural areas and keep them free of domestic dogs to avoid the extinction of the bush dog in Minas Gerais.

It has become evident that the global climate is changing rapidly over the past few decades. The variation and change in the global climatic factors have a notable impact on the local climate of a region. The changing climate is widely regarded as one of the most serious global health threats of the 21st century. Among various kinds of diseases, the most vulnerable to these changes are vector-borne diseases. In the Indian context, particularly Delhi city is the most vulnerable to dengue, a kind of vector-borne disease having its highest impact. We sought to identify and explore the correlation and influence of the global climatic phenomena and local climatic factors with the reported number of dengue cases in Delhi. The temporal expansions of reported dengue cases in Delhi have a variation from its first major outbreak in the city during the year 1996 to 2015. A statistical tool like Pearson Product Moment Correlation (PPMC) is used in this study to establish the interrelationship and the level of impact and local climatic variation on dengue. An exceptional negative correlation value of r = -0.82 between the monsoon index and the dengue incidences was reported during the positive years and also maintains a very high positive correlation with other global climatic indices. The study here finds that there is a strong correlation of climatic variation which further influences the epidemiology of dengue in Delhi.

The forests on the natural distribution area from the silvosteppe zone, under the influence of climate change will experience major changes in their structure and functioning. The analysis of growth parameters for Fraxinus excelsior, Quercus petraea, Q. robur in three experimental areas from center of the Republic of Moldova indicates that the radial growth processes are influenced by the same complex of climatic factors, which differ being dendroclimatic response intensity. It has been shown that between the annual tree growth and forest aridity index - FAI, there are close correlations: the higher FAI values indicate the lower annual growth of the trees, and vice versa, low FAI values identify good development conditions of the stands (higher increases in the annual ring width).

Based on species occurrence records of museum collections, published literature, and unpublished records shared by mammalian experts, we compiled a distribution database for 59 terrestrial mammals populating the extensively protected Dobrogea Region of Romania. The spatial patterns of mammal distribution and diversity was evaluated and systematic conservation planning applied to identify priority areas for their conservation. The spatial analyses revealed that intensive sampling was not directly correlated to mammal diversity but rather to accessibility for inventory. The spatial prioritisation analysis indicated a relatively aggregated pattern of areas with a high or low conservation value with virtually no connecting corridors between them. The significant overlap between Natura 2000 sites and national protected areas induced an over-optimistic vision of the effectiveness and representativeness of existing Natura 2000 network for species found in Annexes II and IV of the Habitats Directive. These results represent a key step in identifying core areas for the protection of mammal diversity and dispersal corridors for improved connectivity, and to guide future conservation efforts in increasing the effectiveness of the existing protected areas in the context of environmental changes.

Abstract The Stemnic river (Buda) is a right side affluent of Bârlad river, with the surface of the catchment basin of 15,662.5 ha. Situated in the central part of the Central Moldavian Plateau, the catchment of the Stemnic (Buda) is characterized by an oblong form (30.5 km, respectively 8.5 km), having a lithologic homogeneity, but also by a diversity of the superficial deposits (eluvia, diluvia, colluvia and proluvia, alluvia). The fields in the catchment basin of the Stemnic (Buda) have been analyzed from the point of view of the soils’ quality, that have been classified into five quality classes. Besides the intrinsic characteristics of the soils, their classification included also the pedo-chemical properties of the lands, geomorphologic or climatic properties of the area. First, second and the third quality classes are predominant in the lower half of the catchment basin, less fragmentary, with prolonged cuesta reverses, corresponding to the distribution area of the chernosols. The lands that form part of the fourth quality class are distributed, in a great percentage, on the same types of soil, but represent greater constrains because of the abrupt cliffs. The fourth class is made up of the lands with severe limitations that reduce the range of agricultural crops or that need special measures or work in order to protect and ameliorate the soil’s resources. This class cumulates a percentage of 9%, being characteristic for the area affected by landslides, prevalent mainly in North-West part of the catchment of the Stemnic (Buda). In the fifth class there are included soils with major constrains for agricultural use. From this perspective, in the catchment, there are predominant the soils in the third quality class (37%), being followed by the second class (26%) and the first class (23%). The main limitative factors for the agricultural production of the lands in the catchment of the Stemnic (Buda) are the erosion in surface, the landslides, humidity excess and the small quantity of nutritive elements.

The aim of this paper is (i) to review the method of valorization of natural resources as applied in the environmental impact assessment, and (ii) to develop recommendations on how valorization expertise should be prepared in order to be comprehensive and transparent. Valorization is the proper time to carry out identi>cation of the possible negative environmental impacts and damages of a planned project. It is recommended to perform valorization due to the state (numbers) and functions (quality) of natural resources. This approach is related to the concept of environmental damage, which is defined as a measurable adverse change in a natural resource or measurable impairment of a natural resource service (which means the functions performed by a natural resource for the benefit of another natural resource or the public). Valorization of natural resources should include an assessment of potential environmental damage, including an impact on the local biodiversity, the ecological connectivity, the N2000 network, and the legally protected areas. The valorization of natural resources should be performed at the following thematic levels focusing on the role of the area under consideration due to: (1) the implementation of the objectives of protection of Nature 2000 network and its overall coherence, (2) the implementation of the objectives of protection of legally protected areas other than N2000, (3) the maintenance of the ecological connectivity in a context other than the coherence of Nature 2000 network, (4) the maintenance of species and natural habitats with favorable conservation status, (5) the conservation of species and natural habitat types that are not legally protected.
