In Europe, Serbia ranks among countries with a high prevalence of Trichinella infection in pigs, which continues to be a serious human health problem. While in some Balkan countries, more than one Trichinella species/genotype has been described in both the sylvatic and domestic cycles, these data are lacking for Serbia. To date, only a few Serbian isolates of Trichinella have been genetically specified, and all were classified as T. spiralis. Although transmission of Trichinella from domestic pigs to wildlife could be assumed, neither the infection status nor the species of Trichinella circulating among wildlife in Serbia has been investigated. This study shows the presence of two Trichinella species, T. spiralis and T. britovi, in wild animals originating from five districts in Serbia, where Trichinella infections in domestic pigs and humans have been recorded. Trichinella spiralis was detected in jackals (n = 3), red foxes (n = 2) and a wild cat (n = 1). We also established that wolves (n = 4) and red foxes (n = 2) serve as sylvatic reservoirs for T. britovi. This is the first report on the presence of T. britovi in Serbia.
Emerging parasitic invasions may have a significant influence on wild and domestic animals, as well as humans worldwide. One of the possible sources of infection is the consumption of the meat of wild animals that enable infectious agents to circulate in the environment and transmit them to human and domesticated animal hosts. Human sparganosis is an emerging and neglected zoonosis worldwide. Most cases are known from Asia; however, a few cases have also been diagnosed in Europeans. Recently, in Białowieża Primeval Forest, northeastern Poland, cases of sparganosis were stated in both intermediate (raccoon dog, badger, wild boar) and definitive hosts (wolf, lynx). Confirmed presence of sparganosis in game species (wild boar) and the possibility of its occurrence in domestic animals (dogs and cats) must be taken into consideration in case this zoonosis is not routinely diagnosed by veterinarians. Plerocercoids in wild boar are located subcutaneously and in muscle tissue. Thus, the emergence of human sparganosis due to consumption of undercooked or smoked wild boar meat is very likely in the areas where wild boar is an approved food source. In this review we describe the biology of Spirometra sp. and the current knowledge about the spread of this tapeworm among wild animals as well as the risk for people, focusing on the situation in Europe.
Several cases of the developing water crisis in semi-arid regions of Tanzania are described. Some cases have transboundary causes. These include Lake Victoria and the riparian population as a result of hydroelectricity developments in Uganda, the Serengeti ecosystem threatened by deforestation of the Mau forest and irrigation in Kenya, and several national parks threatened by irrigation projects within Tanzania. Some of these developments are given national priorities like in case of the Great Ruaha River. Other irrigation projects are driven by the local population to combat poverty. Most of these developments are in breach of state laws because there is no consideration of minimal environmental flows and all have profound negative impacts on people and wildlife downstream. The paper describes the previously unreported case of irrigation in the upper Katuma River that flows into Lake Rukwa, which lead to poverty increase, environmental degradation and a decrease in ecosystem services provision downstream. Governance at the watershed scale in a framework compatible with ecohydrology principles is needed. Such solutions are proposed.

This report presents the beautiful and cultural places in Sri Lanka attracting tourists. Democratic Socialist Republic of Sri Lanka is an island nationin South Asia, located in the Indian Oceanenrich with beautiful white sandy beaches, lush green landscapes varying from rainforests to peakwilderness sanctuaries, Buddhist monasteriesand accented by a cultural history dating back thousands of years.Sri Lankahas been a popular place of attraction for foreign travelers asearly as the 410’s AD/CE, the Chinese traveler Fa-Hienin the twelfth century and the Italian explorer Marco Poloclaiming“best island of its size in the world”. Tourism in the island nationis thethird largest foreign exchange earner. The airport and seaports have been closed to tourists for several months due to the pandemic. Discussions are underway to reopen the airport to tourism under a phased programme in January 2021

Plant: a necessity of life

58%
Plant is one of the major forms of life on earth. It can produce its own food but cannot move about. Plants have well organized structures. They are beautiful and they determine local climates and are used as live fences. They phytoremediate and cool our environment. They provide us with oxygen, medicines, fuel, timber, recreation, industrial products; preservatives, pesticides in addition to all the three necessities of life: food, clothing and shelter. They purify the air and water bodies. It is therefore impossible to talk about life without plants because of their importance to the balance of nature. However, people have altered and often degraded their environment, though it has been taking place so gradually that its effects have not been drastically felt. Despite the enormous benefits of plants to humanity, they are disappearing at alarming rates. The reasons for this loss are many and include many anthropogenic activities. It is therefore quite imperative to ensure their effective conservation. This paper summarizes available information about the direct and the indirect benefits of plants and suggests some important measures to ensure their posterity. I hope, by bringing this information together, people will appreciate our plants and be frugal in using them.
Subject and purpose of work: The study aims to assess the sustainability of rural areas of Western Himalayas during the year 2019. Materials and methods: Aquestionnaire-based survey was conducted in upper Beas Valley of Himachal Pradesh. A total of 101 individuals were interviewed and the questionnaire was filled by the surveyor. Results: Survey showed that high level of unemployment prevailed in the region with minimal monthly income. However, they engaged in agriculture and allied activities along with collection of non-timber forest products (NTFPs) to supplement their incomes. The proximity to protected areas led to frequent encounter with wildlife and such encounters increased after the commencement of Hydro Power Projects. Respondents believed that construction HPPs and expansion road network in the region has increased the occurrence of landslides; and many of them had lost their cultivated land due to landslides. Conclusions: The study showed rural areas of upper Beas Valley were moderately unsustainable.
The Mara River catchment is the dry weather refuge for more than one million migrating wildebeest and zebras of the Serengeti ecosystem. The river flow is affected by developments in Kenya, including deforestation and water diversion for irrigation and the proposed Ewaso Ng’iro (South) Hydropower Project. An ecohydrology model was used to predict the likely impact of these developments on the Serengeti ecosystem. The model was forced by observed monthly rainfall in the period 1900-2000 and calibrated against observations of the number of wildebeest and lions also in the period 1960-1999. The projects are predicted to have little effect on the number of migrating wildebeest in the Serengeti until a drought occurs; historically a drought occurs about every seven years. At that time 20 to 80% of the migrating wildebeest may die, according to the severity and duration of the drought. With a 50% die-off, it may take twenty years for the population to recover; with an 80% die-off there may be no population recovery. In practice the economic benefits would go to Kenya while Tanzania would suffer the economic costs, eg the negative impact on the tourism industry. To ensure sustainable development for both Kenya and Tanzania, a transboundary Mara River management plan needs to be implemented and be compatible with ecohydrology principles for the sustainable use of aquatic resources.
A survey of Babesia, Theileria and Hepatozoon was conducted in wild mammals, including the capybara (Hydrochaeris hydrochaeris; n = 14) from Brazil, the jaguar (Panthera onca; n = 2) and crab-eating raccoon (Procyon cancrivorus; n = 4) from Venezuela, and the red deer (Cervus elaphus; n = 70), red squirrel (Sciurus vulgaris; n = 5) and Eurasian pine marten (Martes martes; n = 3) from Spain. Diagnostic procedures included both microscopy and molecular methods (PCR and sequencing of the 18S rRNA gene). Microscopic examination of blood smears revealed no hematozoan infections — unlike the molecular analyses. Nine Brazilian capybaras were found to be infected with Hepatozoon canis (prevalence 64%), two of which were coinfected with a previously unknown babesid (prevalence 14%) loosely related to Theileria equi (90% 18S rRNA gene similarity according to BLAS® analysis). One jaguar and one crab-eating raccoon from Venezuela were infected by H. canis. Four of the red deer were infected with theilerids (5.7% prevalence), two with Theileria sp. and two with T. annulata. One red squirrel and three pine martens were infected with Hepatozoon sp. The isolate form the red squirrel was phylogenetically related to Hepatozoon sp. reported in Spanish bank voles, whereas those infecting the pine martens were related to Hepatozoon felis reported in Spanish cats. In conclusion, the molecular findings show that some non-canid mammals are carriers of H. canis in South America, while red deer may carry T. annulata in Europe. Small mammals in Europe appear to be unlikely hosts of H. canis and H. felis.
