Mycobacterium avium subspecies paratuberculosis (MAP) causes a significant economic burden in the animal production industry. The purpose of this study was to investigate the prevalence of MAP in the feces of wild duck populations residing along a riverside close to farms in the center of Korea. From wild Spot-billed (Anas poecilorhyncha) and Mallard (Anas platyrhynchos) ducks, 128 fecal samples were collected and analyzed using multiplex real-time PCR, sequencing, and nested PCR to confirm the presence of the organism. The molecular analyses showed that 44 samples (34.4%) were positive for MAP, suggesting a high prevalence of MAP in the wild duck population. Considering the nature and habitat of wild ducks, this result suggests that the organism was introduced from contaminated water from waste of nearby farms, and that the wild ducks may act as a transmitter of the organism to other wild birds or livestock.

This study determined the antibiotic resistance patterns of Escherichia coli and Staphylococcus aureus from the raw meat and feces of three game species from three different farms across South Africa. The Kirby-Bauer disk diffusion method was used according to the Clinical and Laboratory Standards Institute 2018 guidelines. E. coli was tested against ampicillin, ceftazidime, chloramphenicol, streptomycin, sulphafurazole and tetracycline. S. aureus was tested against tetracycline, erthromycin, vancomycin, penicillin, oxacillin and cefoxitin. There were no significant differences in the E. coli antibiotic resistance profiles between the meat and fecal samples (except towards ceftazidime where 5% of the meat isolates were resistant and 0% of the fecal isolates). The S. aureus meat isolates showed high (75%) resistance towards penicillin and on average, 13% were resistant to oxacillin/ cefoxitin, indicating methicillin resistance. The results from this study indicate that there is incidence of antibiotic resistant bacteria from the feces and meat of wildlife species across South Africa, suggesting that cross contamination of the meat occurred during slaughter by antibiotic resistant bacteria from the abattoir personnel or equipment and or from carcass fecal matter. In addition, the results highlight the importance of food safety and hygiene procedures during slaughter to prevent cross-contamination of antibiotic resistant bacteria, as well as pathogens, onto raw meat.

Cat vocalizes to communicate with another and express their internal states. The vocal repertoire of the cat is wide and up to 21 different vocalizations have been described in the literatures. But it is more than probable that the repertoire contains more types of vocalizations. An ethogram was created in this paper describing the actual known vocalisations of the domestic cat based on an auditory classification. However, the audiogram allows also a visual classification which can increase the accuracy of vocalization differentiation. The classification can be risky as it is sometimes unclear if different types of vocalizations are produced in different environments or if a unique type of vocalization is used with variation in the acoustic parameters. As an example, isolation calls produced by kittens differ depending on the context. The environment has an important impact on the vocal behaviour and thus feral cats and pet cats vocalize differently. Pet cats are thus able to create an efficient communication with humans thanks to the flexibility of vocalisation behaviours. This review allowed us to create a simple model of the cat vocal repertory.

A study was designed to investigate the pattern of sexual dimorphism in a plantation of Garcinia kola. Twenty trees were randomly selected for the study and have been observed to flower regularly. A total of 100 inflorescence were randomly collected from the crown of each tree and 500 flowers randomly assessed within the period of four (4) flowering seasons. Floral sex assessment was done visually and with a hand magnifying lens; floral morphometric measurements (i.e. pedicel and perianth length and breadth), inflorescence length, and breadth) was taken using a veneer caliper; number of flowers per inflorescence and inflorescence per twig was counted; while, data analysis was conducted on excel using analysis of variance and pairwise t-test comparison. Four floral sexes were identified in the G. kola plantation studied which were unisexual male flowers, unisexual female flowers, cosexual unisexual male flowers, and cosexual hermaphrodite flowers. Three tree sexes were identified viz: inconstant male, invariant female, and cosexual trees. The plantation was significantly sexually dimorphic in floral sex and phenotypic traits (i.e. pedicel and perianth size), and as well as sexually dimorphic in tree sex and reproductive phenotypic traits (i.e. inflorescence size, number of inflorescences per twig, and number of flower bud per inflorescence). The sexual system of the plantation was therefore trioecious with features suggestive of evolving dioecy through the gynodioecious pathway.

A 14-year-old intact male captive leopard (Panthera pardus) first presented with a focal alopecic lesion on the dorsal aspect of the distal one-third of its tail. Although itraconazole was administered, the lesion progressed deeper and became ulcerated due to self-trauma. Due to the wild nature of the leopard, daily dressing of the wound and replacing the bandages without anesthesia became too dangerous, and amputation became necessary. A postoperative tissue sample was submitted for histopathological examination, and tramadol, amoxicillin/clavulanate, and gabapentin were administered. In the days following the amputation, the leopard's appetite significantly decreased, and the patient passed away 18 days later. Histopathological examination of the specimen revealed well-differentiated squamous cell carcinoma (SCC). In hindsight, had more cells been collected by a fine-needle aspirate (FNA) biopsy or had additional FNA biopsies been performed, SCC might have been diagnosed based on its cytological features rather than delayed histopathological findings. The current study highlights the critical reasons why clinicians may often misdiagnose SCC and the importance of being more aware of potential tumors in ulcerative lesions, which are often incorrectly treated as infectious skin diseases. This is also the first report of cutaneous SCC in a leopard.

The Tibetan Plateau is home to the only alpine crane species, the black-necked crane (Grus nigricollis). Conservation efforts are severely hampered by a lack of knowledge on the spatial distribution and breeding habitats of this species. The ecological niche modeling framework used to predict the spatial distribution of this species, based on the maximum entropy and occurrence record data, allowed us to generate a species-specific spatial distribution map in Ladakh, Trans-Himalaya, India. The model was created by assimilating species occurrence data from 486 geographical sites with 24 topographic and bioclimatic variables. Fourteen variables helped forecast the distribution of black-necked cranes by 96.2%. The area under the curve score for the model training data was high (0.98), indicating the accuracy and predictive performance of the model. Of the total study area, the areas with high and moderate habitat suitability for black-necked cranes were anticipated to be 8,156 km² and 6,759 km², respectively. The area with high habitat suitability within the protected areas was 5,335 km². The spatial distribution predicted using our model showed that the majority of speculated conservation areas bordered the existing protected areas of the Changthang Wildlife Sanctuary. Hence, we believe, that by increasing the current study area, we can account for these gaps in conservation areas, more effectively.

Background: Accurate diagnosis of diseases in animals is crucial for their treatment, and imaging evaluations such as radiographs, computed tomography (CT), and magnetic resonance imaging (MRI) are important tools for this purpose. However, a cross-sectional anatomical atlas of normal skeletal and internal organs of long-tailed gorals (Naemorhedus caudatus) has not yet been prepared for diagnosing their diseases. Objectives: The objective of this study was to create an anatomical atlas of gorals using CT and MRI, which are imaging techniques that have not been extensively studied in this type of wild animal in Korea. Methods: The researchers used CT and MRI to create an anatomical atlas of gorals, and selected 37 cross-sections from the head, thoracic, lumbar, and sacrum parts of gorals to produce an average cross-sectional anatomy atlas. Results: This study successfully created an anatomical atlas of gorals using CT and MRI. Conclusions: The atlas provides valuable information for the diagnosis of diseases in gorals, which can improve their treatment and welfare. The study highlights the importance of developing cross-sectional anatomical atlases of gorals to diagnose and treat their diseases effectively.

Water is an important component in the production of fresh produce. It is mainly used for irrigation and application of pesticides and fertilizers. Several outbreaks cases related to fresh produce have been reported and water has been identified as the most likely source. On the other hand, wildlife has been identified as a possible source of the waterborne pathogens. The purpose of this study was to investigate the effect of wildlife access on irrigation water used in the cultivation of Chinese cabbage in Goesan. The frequency of wild animals access to upstream water source and the contamination level of bacteria such as Escherichia coli and Enterococci of irrigation water used in Chinese cabbage farm was examined. A total of 37 wildlife including the wild bear and water deer were observed in upstream of water source during the cultivation of Chinese cabbage. The result indicated the presence of hygienic indicator bacteria from the upstream where there is no human access. The contamination range of coliforms, E. coli, and Enterococcus spp. Detected in the irrigation water were 2.13~4.32 log MPN / 100 mL, 0.26~2.03 log MPN / 100 mL, and 1.43~3.49 log MPN / 100 mL, respectively. Due to low water temperatures, the contamination levels of coliform bacteria and E. coli in the irrigation water during harvesting time was lower compared to those recorded during transplanting of Chinese cabbage. However, no significant difference was detected in the number of Enterococci during the cultivation of Chinese cabbage. The results indicated the need to manage the microbial risk in irrigation water to enhance safety in cultivation of Chinese cabbage.

The U.S. Conservation Reserve Program (CRP) resulted in the conversion of approximately 14.8 million ha(36.5 million acres) of cropland to grassland, woodland, and other conservation uses throughout the U.S. between 1986 and 1992. One of the major results of CRP has been the addition of millions of hectares of potential wildlife habitat. primarily as grassland. In this study, we examined regional changes in landscape structure caused by the introduction of CRP. Utilizing multi-seasonal Landsat Thematic Mapper imagery, we produced maps of cropland and grassland for the pre- and post- CRP enrollment periods for a six-county region in southwest Kansas. We then applied post-classification differencing to identify regions of cropland that had been converted to CRP. Using the FRAGSTATS spatial pattern analysis program, we calculated a variety of spatial statistics to analyze changes in landscape structure due to CRP. The major impact of CRP in the six-county study area has been the reversal of an overall trend of grassland habitat fragmentation. From the standpoint of potential wildlife habitat, the introduction of CRP has greatly increased the number of patches, mean patch size, and the interior or core area of grassland patches. In addition, CRP has increased connectivity and aggregation between grassland patches, potentially important factors for species of conservation interest, particularly those that require larger expanses of unbroken habitat. Finally, the distance between neighboring patches of grassland has decreased, reducing travel distance between patches. Clearly, the introduction of CRP has substantially modified the spatial structure of the southwest Kansas landscape, with important implications for wildlife habitat.

Forestry as with all land matters, under the Constitution, is a State matter. Thus the States, numbering 14, have considerable autonomy in decisions on forestry and related matters. However, the Federal Government, having jurisdiction over such issues as defence, education and research, endeavours to coordinate, standardise and advise the States on matters where the States have jurisdiction. However, forestry being a major revenue earner, is jealously guarded by the States. Under such circumstances and recognising the interdependencies of impacts of decisions at the State level, the institutional organisations play an important role in coordinating state activities to ensure that the benefits to the country as a whole are not sacrificed in favour of interests of individual state. Various legislative mechanisms have been established to ensure this coordinated effort. A National Forestry Council forms the apex of national political coordination. The Federal Forestry Department is responsible for coordination of developmental activities at the State level, which are implemented be the State Forestry Departments within Peninsular Malaysia. Research is carried out centrally by the Forest Research Institute of Malaysia(FRIM), a statutory body formed in 1985 from a research division of the Forestry Department. The Stares of Sabah and Sarawak have their own Forestry Departments, independent of the Federal Department, and each with its own research unit independent of FRIM. Tertiary education in forestry is the sole responsibility of the Agricultural University at Serdang with a campus for Diploma level training in Sarawak. In the developmental area in the State of Sabah, institutions have been formed to focus on specific areas of activities. The Sabah Foundation is responsible for the long term development of the State forests with a concession of about one million ha. Sabah Forest Development Authority(SAFODA) was formed to carry out reforestation of denuded areas. Sabah Forest Industries Ltd.(SFI) is responsible for the country's only integrated pulp and paper industry with its own afforestation program to support its resource supply. In Peninsular Malaysia various states have established State Corporations to manage large "sustained yield" concessions. While wildlife and state parks are managed by the respective forestry departments in Sabah and Sarawak, it is the responsibility of a separate department in Peninsula Malaysia called the Department of Wildlife and National Parks(under the Ministry of Science, Technology and Environment). Timber trade legislation and promotion in the Peninsular is the responsibility of the Malaysian Timber Industries Board(MTIB) for Peninsular Malaysia and the Sarawak Timber Industries Development Corporation(STIDC) in Sarawak. In the area of NGOs ; the Institute of Foresters Malaysia, is the professional body of forestry in the country. A Malaysian Forestry Society caters for the public participation and interest. Other environmentally related NGOs such as the Malayan Nature Society, the Environmental Protection Society, World Wildlife Fund, Friends of the Earth and the Consumers Associations also involve themselves in specific forestry activities. A number of timber trade associations are also formed by the private sector to assist the industries.
