An animal is considered to have welfare if it has good nutrition and also expresses its innate behavior, including sensations and feelings experienced as a result of physical health. The objective of this study was to evaluate the effect of environmental enrichment on the behaviors of two Asian elephants in a wildlife conservation park. The behavior of two Asian elephants, a 46-year-old male and a 59-year-old female, was observed. Behavior was measured by quantifying the frequency, latency, and duration of behavioral actions. Measurements were done with ad libitum sampling during 5 days of testing, then observations were recorded with focal sampling for 25 days with environmental enrichment and 25 days without enrichment. Data were analyzed with the Chi-square statistical test using the statistical program SPSS 20, observing significant differences (P the application of environmental enrichment. The frequency of maintenance behaviors was higher when environmental enrichment was provided, and the frequency of social conducts (affiliative and agonistic) decreased. In fact, the behaviors most frequently presented by elephants with and without environmental enrichment were definitely maintenance behaviors. The environmental enrichment program helped to reduce the duration of abnormal behaviors and increase the frequency of typical behaviors of the species. It also increased independent movements within the exhibition area and helped to know each of the elephants individually in order to apply each enrichment combination according to their needs.展开更多

Elephants capture the affection of people but also inspire animosity and fear at the same time. This is because there are conflicts with people over space, critical resources, costs of damages and general insecurity to people. This paper examined field evidence and interviewed expert key informants on current intensity and frequency of human-elephants in Amboseli Ecosystem. According to them, generally, the most prevalent (score of 1 lowest to 10 highest) threats to elephants were competition for critical resources (6.32 ± 0.44) followed by blocking of migration (6.24 ± 0.46), harassment of elephants (4.83 ± 0.75), poaching (4.57 ± 0.37), and retaliatory killings (3.78 ± 0.31). For threats that elephants pose to people, the most prevalent one was crop raiding (6.95 ± 0.26) followed by environmental degradation (6.71 ± 0.46), general insecurity to people (5.76 ± 0.65), property destruction (5.16 ± 0.41), injury and death to livestock (3.78 ± 0.37), and injury and death to people (2.71 ± 0.27). For the severity of the threats, the highest score was given to crop raiding whose average score was 7.90 ± 0.24 followed by environmental destruction and degradation (6.89 ± 0.43), injury and death to people (6.72 ± 0.44), injury and death to livestock (6.36 ± 0.50), property destruction (5.78 ± 0.49), general insecurity to people (5.62 ± 0.64). Severity levels followed the same trend or varied slightly. These drivers of human-elephant conflicts need to be addressed decisively to protect both people and elephants. There is a need to ensure local people’s benefit from elephants through ecotourism investments such as wildlife sanctuaries, leasing critical space for elephants’ dispersal on acceptable terms, through appropriate compensation schemes for elephant costs, and supporting local community wildlife rangers to prevent conflicts.展开更多

Data from tw...While the Antarctic Slope Current(ASC) has been intensively studied for the East Antarctica slope area and the Weddell Sea, its fate in the western Antarctic Peninsula(WAP) region remains much less known. Data from two cruises conducted near the South Shetland Islands(SSIs) and the Elephant Island(EI), one in austral summer of 2004 and one in austral winter of 2006, were analyzed to provide a broad picture of the circulation pattern over the continental slope of the surveyed area, and an insight into the dynamical balance of the circulation. The results indicate that southwestward currents are present over the upper slope in the study area, indicating the ASC in the WAP region. Near the Shackleton Gap(SG) north of the EI, the southwestward slope currents near the shelf break are characterized by a water mass colder and fresher than the ambient water, which produces cross-slope density gradients and then vertical shear of the along-slope(or along-isobath) velocity. The vertical shear is associated with a reversal of the along-slope current from northeastward at surface to southwestward in deeper layers, or a depth-intensification of the southwestward slope currents. The water mass with temperature and salinity characteristics similar to the observed cold and fresh water is also revealed on the southern slope of the Scotia Sea, suggesting that this cold and fresh water is originated from the Scotia Sea slope and flows southwestward through the SG. Over the shelf north of the SSIs, the cold and fresh water mass is also observed and originates mainly from the Bransfield Strait. In this area, vertical structure of the southwestward slope currents is associated with the onshore intrusion of the upper Circumpolar Deep Water that creates cross-slope density gradients.展开更多

What the movie lenses hope to express is the same thing that the will of piano music does. Alex is not only a player of the two pieces of piano music but also a singer of the elephant.The thesis applies Schopenhauer's will theory in music to analyze Alex's song《For Elise》and《Moonlight Sonata》and to anatomize his mental activity and brewing of thought. By using the power of piano music this thesis aims at digging out how he becomes the singer of the elephant.展开更多

Therefore, the objectives of the study are to identify the causes, processes and impacts of woodland conversion by elephants and thereby propose a guideline for formulating management strategies. The study is conducted through reviewing published documents on elephant-woodland interaction, factors, mechanisms and processes of woodland conversion to grasslands and impacts on biodiversity have been identified. The study reveals that: 1) the large nutritional and energetic requirements by elephants and high elephant population densities are two driving forces that may cause elephants to convert woodlands to grasslands;2) the process of woodland conversion is not just elephant-tree interaction, but usually included other agents such as fires, droughts or other herbivores. Woodlands are converted to grasslands or scrublands because elephants, fires, droughts and other herbivores prevent recruitment of tree to larger class sizes and regeneration of seedlings of woody plants;3) whereas there are few studies that support biodiversity decline due to impacts of elephants on woodlands, there are studies that indicate woodland disturbance by elephants have benefited and increased diversity of other species. It is concluded that woodland disturbance by elephant is not always detrimental to biodiversity, but may create heterogeneity and suitable habitats for other species. In formulating management strategies, considerations must be made to elephant densities, other agents that interact or work with elephants in woodland conversion and the benefits of woodland changes to biodiversity due to elephants.展开更多

文摘<strong>Objectives:</strong> To describe our technique for the implantation of the Thoraflex Hybrid prosthesis for replacement of the aortic arch in a safe and reproducible way. <strong>Materials:</strong> Thoraflex<span style="font-size:12.0pt;line-height:107%;font-family:;" "="">™</span> Hybrid Plexus Device (Terumo Aortic).<strong> Design:</strong> Drawing on our own experience over the past 4 years in the management of acute type A aortic dissection, we have distilled the essentials of our “Frozen Elephant Trunk” technique which have led us through our own learning curve to the improved management of this taxing condition. <strong>Method/ Results:</strong> Small extension of the median sternotomy incision along the medial border of sternocleidomastoid muscle. End to side graft anastomosis near the origin of the left subclavian artery during cooling on bypass towards 20 degrees. Attention to cardiac protection and maintenance of cerebral perfusion during the shortened corporeal arrest period. Excellent results in 24 consecutive AAAD patients with just one hospital mortality. <strong>Conclusions:</strong> We believe we are entering a new phase in the treatment of AAAD, facilitated by the availability of a hybrid prosthesis which combines expanding stent technology with familiar surgical graft material. Our particular management of the left subclavian artery and of the cerebral circulation during implantation has contributed to an expeditious and reproducible method of treating dissection within the arch of the aorta and beyond.
文摘The film Elephant is novel not only in its narrative style and abundant use of long shots, but also in its selection of two pieces of piano music. What the movie lenses hope to express is the same thing that the will of piano music does. Alex is not only a player of the two pieces of piano music but also a singer of the elephant.The thesis applies Schopenhauer's will theory in music to analyze Alex's song《For Elise》and《Moonlight Sonata》and to anatomize his mental activity and brewing of thought. By using the power of piano music this thesis aims at digging out how he becomes the singer of the elephant.
文摘Geophagy is the deliberate consumption of earth materials such as soils,clays or sediments by human and animals.The ingested soil is chosen based on its physical,chemical,and mineralogical nature.Early studies reveal that geophagy functions through(1) adsorption/absorption of ingested toxic plant compounds onto clay particles,(2)mineral supplementation (Na,Mn,K,and S as the possible candidates),and(3)
文摘The impacts of elephants on woodlands have triggered concerns that elephants were converting woodlands to grasslands in African savannas leading to the loss of biodiversity. Therefore, the objectives of the study are to identify the causes, processes and impacts of woodland conversion by elephants and thereby propose a guideline for formulating management strategies. The study is conducted through reviewing published documents on elephant-woodland interaction, factors, mechanisms and processes of woodland conversion to grasslands and impacts on biodiversity have been identified. The study reveals that: 1) the large nutritional and energetic requirements by elephants and high elephant population densities are two driving forces that may cause elephants to convert woodlands to grasslands;2) the process of woodland conversion is not just elephant-tree interaction, but usually included other agents such as fires, droughts or other herbivores. Woodlands are converted to grasslands or scrublands because elephants, fires, droughts and other herbivores prevent recruitment of tree to larger class sizes and regeneration of seedlings of woody plants;3) whereas there are few studies that support biodiversity decline due to impacts of elephants on woodlands, there are studies that indicate woodland disturbance by elephants have benefited and increased diversity of other species. It is concluded that woodland disturbance by elephant is not always detrimental to biodiversity, but may create heterogeneity and suitable habitats for other species. In formulating management strategies, considerations must be made to elephant densities, other agents that interact or work with elephants in woodland conversion and the benefits of woodland changes to biodiversity due to elephants.
