Abstract Background: Angiostrongylus vasorum is the causative agent of canine angiostrongylosis, a disease that mainly affects domestic dogs and others wild carnivores. In Europe, the number of infected animals is increasing, being mainly located in central and southern countries. In Spain, several studies have reported high prevalences of A. vasorum in wild animals. However, there are no studies that address the current situation and distribution of the disease in domestic dogs in the country. Therefore, the objective of the present study was to evaluate the prevalence of A. vasorum in different areas of Spain. Methods: Between November 2018 and October 2019, blood was sampled from a total of 2024 domestic dogs from 6 eco-epidemiological zones of Spain with climates that favour the presence of competent gastropod mollusks, and tested for the presence of A. vasorum circulating antigens using Angio Detect TM . All included dogs lived outdoors or had regular access to areas with vegetation. Results: The prevalence of canine angiostrongylosis in the studied areas of Spain was 1.73%. No differences were found between males and females. By age, significant higher prevalances were found in dogs younger than 4 years. By eco-epidemiological areas, the highest prevalences were obtained in the north (2.74%) and northwest (1.86%) of Spain, and the lowest was described in the western area (0.93%). Conclusions: The prevalence obtained can be considered high and demonstrates the presence of canine angiostrongylosis in Spain, in those areas where infected wild animals have been described and where climatic conditions are favourable for the establishment of the disease. Prophylactic measures should be prescribed for dogs at risk of infection and veterinarians should be aware of the importance of this disease.

Abstract Background: Angiostrongylus vasorum is the causative agent of canine angiostrongylosis, a disease that mainly affects domestic dogs and others wild carnivores. In Europe, the number of infected individuals is increasing, being located in central and southern countries. In Spain, several studies have reported high prevalence of A. vasorum in wild animals. However, there are no studies that address the current situation of the disease or its distribution in domestic dogs, and complaints from veterinary personnel are very limited. Taking into account these facts, the objective of the present study was to evaluate the prevalence of A. vasorum in different areas of Spain.Methods: Between November 2018 and October 2019, blood was sampled from a total of 2024 domestic dogs from 6 zones of Spain with climatologies that favour the establishment of the disease, where all dogs included in the study lived outdoors or had regular access to areas with vegetation and none had traveled outside the study area of ​​interest in the past year. Details about their gender and age were collected. All dogs were tested for the presence of A. vasorum circulating antigens using AngioDetectTM. Results: The prevalence of canine angiostrongylosis in the studied areas of Spain was 1.73%. No differences were found between males and females but by age, significant differences were found between dogs <1 years and the rest of three groups of age. By eco-epidemiological areas, the highest prevalences were obtained in the north and northwest of Spain and the lowest was described in the central area.Conclusions: Our data suggest that the disease is present in Spain in domestic dogs where previously infected wild animals existed or where climatic conditions are favourable for the establishment of the disease.

Rabies Diagnosis

In order to obtain an overview of the situation of rabies positive cases, but also to establish a true prevalence of the disease among domestic and wild animals, an epidemiological survey was conducted in the north east of the country, targeting the 8 counties of Moldova region,over a period of eight years, between 2010 and 2017. A total of 2306 brain samples coming from animals with suspicion of rabies were received at the laboratories, from which 851 (36,90 %) were represented by domestic animals and 1455 (63,10 %) by wild animals. Following the implementation of the referenced techniques in rabies diagnosis, out of 2306tested samples, 492 (21,36%) were confirmed positive and 1814 negative (78,66%). Out of 1455 samples coming from wild animals, 303 (20,82 %) were confirmed positive, with a total prevalence of 21,32 %, while in the case of domestic animals out of 851 samples, 189 were positive, with a total prevalence of 22,20 %.

A growth in the number of deer and an increase in their productivity are closely related to the solution of the complex problem of reproduction and rational use of deer females. Significant damage to reindeer husbandry is caused by the barrenness of northern domestic deer, the level of which has been quite high in recent years. So, in the Republic of Sakha, on 01.01.2020, the number of domesticated reindeer was 152,068, of which female deer and heifers — 71,818, offspring per 100 females — 59, business yield amounted to 52 fawns per 100 females. The causes of infertility are very diverse, as the natural and climatic conditions of the breeding zones have a significant influence on the reproductive function of reindeer. In Yakutia, the main population of northern domestic deer is bred in mountain taiga and tundra natural-climatic zones, so there are about 55 thousand deer in the mountain taiga zone and more than 65 thousand deer in the tundra zone. In this regard, the study of the peculiarities of the postpartum period course in domestic reindeer females, its morphophysiology, and behavioral reactions depending on the natural and climatic conditions of breeding is of great importance.

Впервые в мире создана популяция зубров на территории 60 градусов северной широты. В новых климатических условиях разведения и сохранения зубров определены и проанализированы факторы существования вида на севере Европейской части РФ. Выявлены признаки, динамика численности, которые являются составной частью системы, предназначенной для управления биоразнообразием. Интродукция, являясь процессом введения в экосистему нехарактерных для нее видов, может усиливать изменения биоценозов как положительно, так и отрицательно. Насколько быстро и успешно проходит процесс адаптации заселенного вида, и усматривается его влияние на окружающую среду зависит дальнейшее существование зубров и в целом биоразнообразия. В статье обсуждаются вопросы взаимоотношения зубров с другими видами копытных и хозяйственной деятельностью человека, а также дальнейшим использованием зубров в сельскохозяйственном производстве. Пластичность зубров, выявление изменений и их анализ при вселении видов в новые условия обитания необходимы не только для определения развития или деградации биоценозов и в целом экосистемы, но и прогноза социально-экономических последствий интродукции как одного из методов сохранения редких и исчезающих видов фауны.For the first time in the world, a bison population has been created in an area of 60 degrees north latitude. In the new climatic conditions of breeding and preservation of bison, the factors of the species existence in the north of the European part of the Russian Federation are identified and analyzed. The signs, dynamics of abundance, which are an integral part of the system designed to manage biodiversity are identified, since the preservation of biological diversity on the planet is one of the main problems of our time. Introduction, being the process of introducing non-typical species into an ecosystem, can enhance changes in biocenoses, both positively and negatively. The question posing sounds especially when it comes to such a large hoofed animal as the European bison. How quickly and successfully the process of adaptation of the universe takes place and its environmental impact is seen depends on the continued existence of bison and biodiversity in general. The article discusses the relationship of bison with other types of ungulates and human activities, as well as the further use of bison in agricultural production. How these issues will be resolved positively depends on the future of these animals. Thus, the plasticity of bison, the identification of changes and their analysis, with the introduction of species into new habitat conditions is necessary not only to determine the development or degradation of biocenoses and the ecosystem as a whole, but also to predict the socio-economic consequences due to the introduction as one of the methods of preserving rare and endangered species of fauna.

Our study compares the content in polyphenolic compounds and hypericin, in four species of Hypericum - H. perforatum L., H. maculatum Cr., H. hirsutum L., H. tetrapterum Fr. (syn. Hypericumacutum Mnch.) harvested from spontaneous flora in the north-western area of Transylvania, Romania. These species represent an important source of such compounds with different biological actions. After making the extracts, they were subjected to HPLC-SM analysis. The presence of rutoside in the largest amount (462.82 mg %) in the H. perforatum extract was observed, this containing most of the flavonoid heterosides. For the species H. maculatum, the presence in a much higher amount of the hyperoside (976.36 mg %) is characteristic compared to the other species. Quercetol is the best represented of the flavonoid aglycons, its concentration being the highest in H. hirsutum (659.66 mg %). The hypericin content ranges from 0.2171 g % in the H. tetrapterum extract, to 0.0314 g % in the methanol extract of H. maculatum.The highest antioxidant properties measured by FRAP method were recorded in the case of H. perforatum and H. maculatum.

Continuous Plankton Recorder records from the North Sea and north-east Atlantic from September 1997 to March 1998 indicate an exceptional influx of oceanic indicator species into the North Sea. These inflow events, according to historical evidence, have only occurred sporadically during this century. This exceptional inflow and previous inflow events are discussed in relation to their similarity in terms of their physical and climatic conditions.

Abstract Changes in runoff parameters are very important for Slovakia, where stream-flow discharges, being supplied by precipitation and groundwater runoff, are preferentially influenced by climatic conditions. Therefore, teleconnections between runoff parameters, climate parameters and global atmospheric drivers such as North Atlantic Oscillation, Southern Pacific Oscillation, Quasi-biennial oscillation and solar activity were studied in the Nitra River Basin, Slovakia. Research was mostly based on records of 80 years (1931-2010) for discharges and baseflow, and 34 years for groundwater heads. Methods of autocorrelation, spectral analysis, cross-correlation and coherence function were used. Results of auto- correllograms for discharges, groundwater heads and base flow values showed a very distinct 11-year and 21-year periodicity. Spectrogram analysis documented the 11-year, 7.8-year, 3.6-year and 2.4-year periods in the discharge, precipitation and air temperature time series. The same cycles except of 11-years were also identified in the long-term series of the North Atlantic Oscillation and Southern Pacific Oscillation indices. The cycle from approximately 2.3 to 2.4-years is most likely connected with Quasi-biennial oscillation. The close negative correlation between the North Atlantic Oscillation winter index and the hydrological surface and groundwater parameters can be used for their prediction within the same year and also for one year in advance.

AbstractA study was conducted in 2000 and 2003, following the collapse of the commercial fishery in 1990, to compare metazoan parasites of Atlantic cod Gadus morhua, captured off coastal Labrador, with samples taken in 1980 and 1986. Fish were captured by otter trawl offshore in the North Atlantic Fish Organisation subarea 2J. Parasites were removed from the digestive tract, stained, identified and compared between the different groups. Both the prevalence and mean abundance of trematodes, larval nematodes and E. gadi were significantly lower in fish taken in 2000 and 2003 than in 1980. While mean values of trematodes and nematodes declined in 1986, those of Echinorhynchus gadi remained unchanged in 1986 and 1990. Four-year-old cod sampled in 1990 harboured significantly fewer E. gadi than older age groups. The most commonly occurring trematodes included Podocotylereflexa, Lepidapedon elongatum, Derogenes varicus and Hemiurus levinseni while the larval nematode, Anisakis sp. was predominant. Comparison of offshore samples taken in 2000 and 2003 with others taken in previous years suggests an overall decline of parasites coincident with a change in climatic conditions, the absence of a major food source, namely capelin Mallotus villosus, of cod and ultimately the decline of the Labrador population.

Soviet medicine has set a very serious task for the health resorts to quickly, possibly fully and permanently restore the health of the working people. To accomplish this task, a tremendous amount of work was required to restore the resorts and adapt them for the mass admission of workers. However, the demand for spa treatment has significantly outgrown the possible supply, the nationwide resorts do not meet the needs felt in spa treatment. In addition, a trip to distant resorts with climatic conditions completely alien to the patient forces the patient to spend a lot of time and effort on acclimatization, and returning from the southern resorts to the harsh climatic conditions of the north often negates the results achieved at the resort
