The methodological approach and methodical problems of evaluation and mapping of biodiversity of mountain forest territory in Primorsky Krai (south of the Russian Far East) are considered. The complex evaluation of biodiversity is presented according to the scheme: (ecotopical environments → vegetation → animal population) ← fire-danger. It is proposed to compile the maps of ecotopical diversity on a basis of diversity index and contrast of relief characteristics, and the maps of geobotanical and zoological diversity — on a basis of spatial extrapolation of indexes relating biota to environmental conditions. The examples of construction of appropriate maps are given for Primorye Region.

Excessive hunting and poaching for commercial purpose of Varanus salvator in Indonesia can cause a decline in this animal population. However, the scientific information of this animal especially about the biologic of organ system is rarely reported. Therefore, this case opens up opportunities for researching, which aims to study the anatomy of digestive tract of water monitor macroscopically. This research has been conducted in Biology Laboratory, University of Muhammadiyah Kupang for 5 months from March to August 2016. The digestive organ of this animal that has been preserved in alcohol 70% was obtained before from two males of water monitors. Preservation process: the animal were anesthetized, exsanguinated, and fixated in 4 paraformaldehyde by tissue perfusion method. Observations were performed to the visceral site and morphometrical of digestive tract. The resulted data was analysed descriptively and presented in tables and figures. The digestive tract of water monitor consist of esophagus, stomach, small intestine, large intestine and cloaca. The dimension of each organ is different based on its structures and functions. The esophagus of water monitor connects the mouth cavity and the stomach and also as the entrance of food to the stomach. Water monitor stomach were found in cranial part of abdomen, in left side of liver. The small intestine was longer than stomach and it is a winding muscular tube in abdomen in posterior side of liver. The large intestine consist of colon and cloaca, while cecum was not found. This channel was extend lateromedially in abdomen to cloaca between left and right kidneys. The cloaca was the end of digestive tract which excreted feces and urine. From this research, we can conclude that the digestive tract of water monitor consists of esophagus, stomach, small intestine, and large intestine. It’s difficult to differentiate small intestine and large intestine because there are no cecum.

Parasite Exposure

AbstractTo date, there are no recent studies identifying the prevalence of parasites of human and veterinary importance in dogs and cats in Ireland. The interaction between pets and wildlife species in the environment is an important source of parasite exposure to canids and felines, and one likely to be heightened in the stray animal population. This study aimed to establish the prevalence of endoparasites in unowned dogs and cats in County Dublin, Ireland. Feces from stray dogs (n= 627) and cats (n= 289) entering a rehoming centre were collected immediately after defecation. The main parasitic agents detected were ascarids (15.52 and 30.26%),Cystoisospora(3.27 and 3.69%),Giardiaspp. (6.02 and 1.84%) and lungworms (0.64 and 2.08%), in dogs and cats respectively. Animals younger than 3 months of age were more likely to be infected with ascarids (P< 0.001) andCystoisosporaspp. (P= 0.008 andP= 0.014) than older animals. All lungworms were morphologically identified and dogs were infected withAngiostrongylus vasorum(0.48%) andCrenosoma vulpis(0.16%) whereas cats were only infected withAelurostrongylus abstrusus(2.08%). This represents the first prevalence study of stray animals in Ireland. Data collected will inform the treatment and in addition, the future monitoring and control studies of parasite populations.

Faunal remains obtained from archaeological sites in the Kruger National Park, provide valuable information on the distributions of animal species in the past. The relative abundances of some species are compared with animal population statistics of the present. The study of the faunal samples, which date from nearly 7 000 years before present until the nineteenth century, also provides insight into climatic conditions during prehistoric times.

Leptospirosis is a cause of great economic damages in cattle-breeding, and it is a great sanitary problem for human health. Therefore we tried to examine the situation in our area, through a period of 15 years, from the in year 1988. until year 2002.We gained insight into the spread of the sickness on our epizootic area, both for the animal population and for the human population.

Castration in domestic and companion animals plays an important role in controlling animal population, aggressive male behaviour and producing meat with a consistent quality acceptable to consumers. Surgical castration is the widely used method, but it is more expensive and painful if not well managed. This research focused on the use of 10% iodine and 1% polidocanol foam as intratesticular injections to achieve castration in three adult dogs owned by a client in Lwandeti village in Kakamega County, Kenya. Two of the dogs received 1ml of 1% polidocanol, while one dog received 1ml of 10% iodine in each of their testicles. The testicles were surgically harvested after three months for histological examination. The histological examination revealed that the seminiferous tubules of testes those received 10% Lugol’s iodine had cellular infiltration and fibrin deposition. Those that received 1% polidocanol showed moderate to severe cellular infiltration but less than the iodine group. This study has shown the potential of polidocanol and iodine as chemical methods that can be used instead of surgical castration.

COVID19 is posing threat cosmopolitically encompassing more than 200 countries and making threat to entire population globally as pandemic. The cats, dogs and bovine are at threat which are close partner to human population. The veterinarians specially practicing are at risk when they encounter the sick animals. This study focus to the Pakistani veterinarian where animal population is under estimated or sometimes census is not performed. As Current population of domestic animals in Pakistan consist of 23.34 million buffaloes, 22.42 million cattle, 24.24 million sheep, 49.14 million goats, and with a huge population of dogs and cats without official census which may pose a threat to innocent population and even more a practicing veterinarian and veterinary paramedics are more at threat, if god forbids. There is need for further investigation its role and zoonotic perspective. Regarding practicing field veterinarians fighting without weapons against mass destructing pathogen and making vulnerability on wide.
