Insect’s class is the most numerous, comprising more than 1 million species. Insects have inhabited a variety of terrestrial habitats, soil, fresh water, coastal seas. A large variety of habitats in the terrestrial environment contributed to the speciation and the wide distribution of this large group of arthropods. Most insects benefit as plants pollinators, some of them produce substances (honey, wax, varnish, silk), which are used as food products and raw materials for industry. Through the large biomass and diversity of trophic relations, insects take part in the biosphere circulation of substances, in soil formation processes. Among the insects that do not benefit, there are pests of forest and agricultural crops, carriers of plant, animal and human diseases. For example, potato or Colorado potato beetle (Leptinotarsa, Doryphora, decemlineata Say). It belongs to the tongs family (Crysomelidae), up to 1 sm in length and up to 7 mm in width. Their body is reddish-yellow, elytra light yellow with 5 black longitudinal stripes; there are several black dots on their chest shield, sometimes merging into spots; the apex of thickening antennae and the posterior margin of the head are also black. The potato beetle was discovered and described in 1823 in the Rocky Mountains, where it inhabited and ate at the expense of wild-growing members of the nightshade family (Solaneae); later it switched to the colonists potato plantations. The first devastations produced by it were noticed in 1859 in the state of Colorado hence the name of the beetle.1–6 The Colorado potato beetle causes great damage to the potato crop. Destruction is an important issue. The Colorado potato beetle has a multi-chamber heart. We believe that this is the most vulnerable part of his body. The heartbreak leads to the death of the Colorado potato beetle. This determines the relevance of the chosen topic. The aim of this work was to simulate a multi-chamber system of insect heart, to determine the rigidity of its multi-chamber system and the resonant frequency.
昆虫纲是数量最多的,有100多万种。昆虫曾栖息于各种陆地生境、土壤、淡水、沿海海域。陆地环境中各种各样的栖息地促成了这一大群节肢动物的物种形成和广泛分布。大多数昆虫作为植物传粉者受益,它们中的一些产生物质(蜂蜜,蜡,清漆,丝绸),这些物质被用作食品和工业原料。通过巨大的生物量和多样性的营养关系,昆虫参与生物圈物质循环,参与土壤形成过程。在不受益的昆虫中,有森林和农作物害虫,植物、动物和人类疾病的携带者。例如,马铃薯或科罗拉多马铃薯甲虫(Leptinotarsa, Doryphora, decemlineata Say)。它属于钳科(Crysomelidae),长可达1厘米,宽可达7毫米。身体呈红黄色,鞘翅淡黄色,有5条黑色纵条纹;它们的胸盾上有几个黑点,有时会合并成斑点;增厚触角的顶端和头的后缘也是黑色的。马铃薯甲虫于1823年在落基山脉被发现并被描述,它在那里居住并以野生生长的茄科(茄科)成员为食;后来,它转向了殖民者的马铃薯种植园。1859年,人们在科罗拉多州发现了这种甲虫造成的第一次破坏,因此这种甲虫得名。科罗拉多马铃薯甲虫对马铃薯作物造成巨大损害。破坏是一个重要的问题。科罗拉多马铃薯甲虫有一个多腔心脏。我们认为这是他身体最脆弱的部位。心碎导致科罗拉多土豆甲虫死亡。这决定了所选主题的相关性。本工作的目的是模拟昆虫心脏的多腔体系统,确定其多腔体系统的刚度和谐振频率。

Trichomoniasis, caused by a protozoan parasite, has been known for many years in pigeons and doves and also in birds of prey, but in 2005 it emerged in finches, first causing necrotic ingluvitis, infection of the crop.1 Since then epidemic mortality has occurred every year in the late summer and early autumn in birds visiting garden feeding stations, and particularly in Greenfinches (Chloris chloris). In the first year this disease led to a reduction in greenfinch populations of 35% and in chaffinches of 20% in areas with highest reports of the condition. Before the outbreak these finch species were seen in around 80% of gardens yet in the years following first reports of the disease sightings have halved.2 Now in the UK the International Union for the Conservation of Nature (IUCN) Red list classifies the breeding greenfinch population as endangered. Spread to Europe seemed to occur in 2008 with the same A1 clonal strain of Trichomonas involved. It appears that year-round feeding of garden birds at stations such as bird tables and congregation of birds at such localities has led to the spread of this condition.3
滴虫病是由一种原生动物寄生虫引起的,多年来人们已经知道它在鸽子和鸽子以及猛禽身上存在,但2005年它在雀类身上出现,首先引起坏死性肠衣炎,即作物感染从那时起,每年夏末和初秋,到访花园喂食站的鸟类,特别是绿翅雀(Chloris Chloris),都会发生流行病死亡。在该病报道最多的地区,该病第一年导致绿翅雀种群减少35%,苍头燕雀种群减少20%。在疫情爆发之前,这些雀类出现在大约80%的花园中,但在首次报告疾病目击事件后的几年里,这些雀类的数量减少了一半现在在英国,国际自然保护联盟(IUCN)的红色名录将繁殖中的绿翅雀种群列为濒危物种。传播到欧洲似乎发生在2008年,涉及相同的A1毛滴虫克隆株。看来,在诸如鸟桌之类的站点,花园鸟类的全年喂养和这些地方鸟类的聚集导致了这种情况的蔓延

Ecotourism is a form of tourism involving visiting fragile, pristine and relatively undisturbed natural areas intended as a low impact and often small scale alternative to standard commercial tourism. It is about creating and satisfying a hunger for nature, about exploiting tourism’s potential for conservation and development and averting its negative impact on ecology, culture and aesthetics. Wildlifebased tourism can be regarded as a type of ecotourism, and is often perceived to be effective in promoting conservation of important species and habitats in developing countries.1 Recent studies across the world has revealed that the number of tourists seeking interactions with wildlife in their natural environment is increasing,2,3 and has led to high revenues generated from wildlife tourism.
生态旅游是一种旅游形式,涉及访问脆弱,原始和相对未受干扰的自然地区,旨在作为标准商业旅游的低影响和小规模替代。它是关于创造和满足对自然的渴望,关于开发旅游业的保护和发展潜力,并避免其对生态、文化和美学的负面影响。以野生动物为基础的旅游可以被看作是一种生态旅游,在发展中国家通常被认为对促进重要物种和栖息地的保护是有效的最近世界各地的研究表明,在自然环境中寻求与野生动物互动的游客数量正在增加,并导致野生动物旅游产生高额收入。

Emu farming in India is gaining commercial importance. Report on leg deformities due to hypocalcaemia was scanty for emu birds. Hence, this communication reports investigated effect of calcium levels on emu birds specifically as a cause for leg deformities (Figure 1 &2). Birds were administered with oral calcium preparations (Syrup containing vitamin A, Calcium and Vitamin D3 and vitamin B12) daily twice in drinking water for the period of three months.

The probabilities of species colonization and extinction rates of meta-populations on island system could be affected by fraction of islands occupied and size of each island. Meta-population models are relevant to understand the dynamics of endangered species which often persist in highly fragmented landscapes. The objectives of the study were to: (1) determine the meta-population dynamics of the endemic lava heron ( Butoridessundevalli ) on the archipelago island system through estimating the probabilities of colonization and extinction rates; (2) investigate the structure of meta-populations and their trends on the island system by using meta-population models. The results revealed that islands which are large in size showed a source-effect due to their positive internal rate of population growth, lower probabilities of extinction rates, and higher average abundance of population size. However, islands with small size had lower average abundance of population size and relativity lower (negative) internal rate of population growth so that they acted to play a sink-effect. In contrast to the prediction made by meta-population model, the results of the comparison across the twelve islands showed that both the probabilities of colonization and extinction rates of the small sized islands were relatively higher than those islands with large size. However, across time frame comparison showed that the extinction probabilities increased with the increase in fraction of occupied islands though colonization probabilities showed a slight decline when the fraction of occupied islands increased. This suggested that the meta-population structure of the endemic lava heron on the archipelago island system was found to be the combination of source-sink and core-satellite structure. Fraction of islands occupied, and the area of islands had a significant effect to predict the internal rates of population growth and the average abundance of population size for the endemic lava heron on the archipelago island system, respectively.
岛屿系统上元种群的物种定殖率和灭绝率可能受到岛屿占比和岛屿大小的影响。元种群模型有助于理解濒危物种在高度破碎化的景观中生存的动态。本研究的目的是:(1)通过估算熔岩鹭(Butoridessundevalli)在群岛岛屿系统上的定殖率和灭绝率,确定其元种群动态;(2)利用元种群模型研究海岛系统的元种群结构及其变化趋势。结果表明,面积较大的岛屿由于其正的内部人口增长率、较低的灭绝率概率和较高的平均人口规模丰度而表现出源效应。然而,面积小的岛屿人口规模的平均丰度较低,人口内部增长率相对较低(负),因此它们发挥了下沉效应。与元种群模型的预测结果相反,12个岛屿间的比较结果表明,小岛屿的定殖概率和灭绝率均高于大岛屿。然而,跨时间框架的比较表明,灭绝概率随着被占领岛屿比例的增加而增加,而殖民化概率随着被占领岛屿比例的增加而略有下降。这表明该群岛系统特有熔岩鹭的元种群结构为源-汇与核心-卫星结构的结合。岛屿占比和岛屿面积分别对群岛岛屿系统特有熔岩鹭种群内部增长率和种群规模平均丰度有显著影响。

Scaling of total evaporative water loss and evaporative heat loss in birds at different ambient temperatures and seasons 不同环境温度和季节下鸟类总蒸发失水和蒸发热损失的标度

Endothermic animals exchange heat with the environment via four modes: conduction, convection, radiation and evaporation). Evaporation is of significant ecological interest. Evaporation from an animal always results in a decrease in the temperature of the surface from which the evaporation occurs. Therefore, evaporation is oneway transfer which causes heat loss from the organism. Biological evaporation always implies loss of water which is a vital resource for nearly all biochemical processes. Evaporation is the loss of heat via the loss of body mass.1 First guidance for the direct weighing method to determine evaporative water loss was obtained from the studies of Hutchinson and Sykes2 and Hutchinson3 on evaporation in domestic fowl. Robert С Lasiewski, Alfredo L Acosta and Marvin H Bernstein using new techniques and equipment, invented new methods different from the original method. A major disadvantage of the direct weighing method is that it does not permit the simultaneous determination of the energetic cost of evaporative cooling by monitoring oxygen consumption or carbon dioxide production, as is possible in the open flow method. As previous studies have shown,4–7 it is possible to determine evaporative heat loss from the ratio (q) between heat production (RM) (determined by the rate of oxygen consumption) and body mass loss (Dm) at various ambient temperatures (TA): q=RM/Dm. High water loss necessitates regular water ingestion through drinking, consuming water in food, and metabolic water production. The method is based on the law of conservation of mass where the total mass of the reactants equals the total mass of the products leading to the insight that the relations among quantities of reactants and products typically form a ratio of positive integers (stoichiometry). The method uses the metabolic rate (oxygen consumption) of the bird at thermo neutral ambient temperatures (TA), respiratory quotient (RQ), the loss of body mass and the energetic equivalent of the loss of body mass (q) as the ratio between heat production and the loss of body mass. It is known that the loss of mass in bird exposed to controlled conditions is due to three major factors:8–10
吸热动物通过四种方式(传导、对流、辐射和蒸发)与环境交换热量。蒸发具有重要的生态意义。动物的蒸发总是导致发生蒸发的表面温度下降。因此,蒸发是导致有机体热量损失的单向传递。生物蒸发总是意味着水的损失,而水是几乎所有生化过程的重要资源。蒸发是通过身体质量的损失来损失热量Hutchinson and Sykes2和Hutchinson3对家禽蒸发量的研究为直接称重法测定蒸发水分损失提供了第一个指导。Robert С Lasiewski, Alfredo L Acosta和Marvin H Bernstein利用新的技术和设备,发明了不同于原有方法的新方法。直接称重法的一个主要缺点是,它不允许通过监测氧气消耗或二氧化碳产生来同时确定蒸发冷却的能量成本,而开放流量法可能做到这一点。正如先前的研究所表明的,4-7可以通过不同环境温度(TA)下产热(RM)(由耗氧量决定)与体重损失(Dm)之间的比值(q)来确定蒸发热损失:q=RM/Dm。高失水需要通过饮用、食物中的水分摄入和代谢水的产生来定期摄入水分。该方法基于质量守恒定律,即反应物的总质量等于生成物的总质量,从而认识到反应物和生成物的数量之间的关系通常形成正整数的比例(化学计量学)。该方法使用鸟类在热中性环境温度(TA)下的代谢率(耗氧量)、呼吸商(RQ)、体重损失和体重损失的能量当量(q)作为产热与体重损失之间的比值。众所周知,暴露在受控条件下的鸟类的质量损失是由于三个主要因素:8-10

Mammals are an important ecological constituent of terrestrial ecosystems.1 Large−sized mammals (weigh more than 7kg) and medium−sized mammals (weigh between 2 and 7kg),2 in particular have important ecosystem functions.3 They regulate plant diversity and structure and potential pest species through hervibory, other animal populations through predation, and plant dispersion through seeds consumption.1,4 Large and medium−sized mammals are very sensitive and intolerant to disturbance and indicators of the healthiness and integrity of ecosystem.4–6 Mammals also act as umbrella species because of their large area home range requirements and contribute to the conservation of other species.1,4

Carrier pigeons are highly valued for their outstanding orientation skills and high performance that they display during races. The breeding of the carrier pigeon is very important for these reasons. Increased stress and short time for regeneration during the race are an important factors that significantly affects the health of racing pigeons and their composition of bacterial microflora. The aim of this study were to observe the health status and changes in bacterial microflora of 80 racing pigeons in age 1.5 - 4 years originated from holding on west of Slovakia , which for three months completed eighteen races at a distance of 120 - 1150 km. At the beginning and at the end of the race season were taken the samples of swabs from cloaca and oropharynx. Comparing the most common diseases of pigeons, were found an increased incidence of coccidiosis (52.2%), trichomoniasis (31.9%), and respiratory syndrome (7.2%) after the race season. The enterococcal and streptococcal intestinal flora of pigeons during the race season was dominated and composed of mainly host specific bacteria by Ent. faecalis , Ent. faecium , Ent. columbae , E. coli , Str. gallolyticus and Str. faecalis . Results are showing that also despite increased percentage of cultivation opportune pathogens, especially coagulase negative and positive staphylococci and increased prevalence of coccidiosis, trichomoniasis and respiratory syndrome, the pigeons are able to provide flight performance and cope with changes in their organism during this difficult race period.
信鸽因其出色的定向能力和在比赛中表现优异而受到高度重视。由于这些原因,信鸽的饲养是非常重要的。赛鸽在比赛过程中压力的增加和恢复时间的缩短是影响赛鸽健康及其菌群组成的重要因素。本研究的目的是观察80只年龄在1.5 ~ 4岁的赛鸽的健康状况和细菌菌群的变化,这些赛鸽来自斯洛伐克西部的holding,在三个月内完成了18场比赛,距离120 ~ 1150公里。在赛季开始和结束时,从泄殖腔和口咽处采集拭子样本。比较鸽子最常见的疾病,发现球虫病(52.2%)、滴虫病(31.9%)和呼吸综合征(7.2%)的发病率在赛季后增加。赛鸽肠道菌群以肠球菌和链球菌为主,主要由宿主特异性菌群组成。粪,肠;屎,恩特。大肠杆菌、大肠杆菌、溶胆链球菌和粪链球菌。结果还表明,尽管培养的适宜病原体,特别是凝固酶阴性和阳性葡萄球菌的百分比增加,球虫病、滴虫病和呼吸综合征的患病率增加,但鸽子能够提供飞行性能,并在这一艰难的比赛期间应对其机体的变化。

Anaesthesia is an indispensable pre-requisite to most of the surgical interventions, both in humans and animals, so that the surgeon can perform surgical intervention with maximum precision and sagacity. Anaesthetics are available for both parenteral as well as inhalation routes in canine surgery. Due to meager facilities available for field veterinarians in Pakistan, intravenous anaesthetics are preferred because of their early and safe induction. Ketamine hydrochloride has been the sole anaesthetic agent so far relied upon by the veterinarians for most of surgical interventions. Its unavailability or irregular availability in local market renders the veterinary surgeons incapable of performing any intervention on canine surgical patients. This situation compels the veterinary surgeons/ practitioners to look for some other suitable and safe alternative readily procurable from the market having better or an equivalent spectrum of anaesthesia. Propofol is a unique non-barbiturate, non-steroid, short-acting general intravenous anaesthetic agent.1 It is associated with a rapid smooth induction and a rapid recovery.2 More advantageously, it is readily available in the market. Anaesthetic stage duration of propofoland midazolam could be enhanced if used in combination with ketamine hydrochloride. This hypothesis lead us to study the anaesthetic efficacy of propofol in combination with ketamine hydrochloride and to compare it with combination of propofol mizadolam in dogs.
麻醉是大多数手术干预不可或缺的先决条件,无论是在人类还是动物中,这样外科医生才能以最大的精度和智慧进行手术干预。麻醉药可用于肠外和吸入途径在犬手术。由于巴基斯坦的野外兽医设施贫乏,静脉麻醉是首选,因为它们可以早期安全诱导。迄今为止,氯胺酮盐酸盐是兽医在大多数手术干预中所依赖的唯一麻醉剂。在当地市场上无法获得或不定期获得,使得兽医无法对犬类手术患者进行任何干预。这种情况迫使兽医医生/从业人员寻找其他合适和安全的替代品,可以从市场上轻易获得,具有更好或等效的麻醉范围。异丙酚是一种独特的非巴比妥酸盐、非类固醇、短效全身静脉麻醉药它与快速平稳的诱导和快速恢复有关更有利的是,它在市场上很容易买到。异丙酚咪达唑仑与盐酸氯胺酮合用可延长麻醉期。根据这一假设,我们研究了丙泊酚与盐酸氯胺酮联用对犬的麻醉效果,并与丙泊酚咪唑仑联用进行了比较。

Previously, new data were obtained on the study of the properties of a 5% solution of pyridoxine hydrochloride in relation to the development of processes of complicated action of 10% solution of isoniazid for intravenous administration in a modular animal experiment. They allowed to reveal the presence of a pronounced protective action, which was attributed to the value of the indicator in the therapeutic and protective index. These toxicological studies indicate the possibility of developing a system of measures for the treatment and antidote effects of pyridoxine on the overdose of isoniazid, which is extremely important in the widespread use of drugs for the treatment of tuberculosis.
此前,在模块化动物实验中,研究了5%盐酸吡哆醇溶液的性质与10%异烟肼溶液静脉给药复杂作用过程的关系,获得了新的数据。它们揭示了明显的保护作用的存在,这归因于该指标在治疗和保护指数中的价值。这些毒理学研究表明,有可能制定一套措施系统来治疗吡哆醇对异烟肼过量的治疗和解毒剂作用,这在广泛使用治疗结核病的药物中是极其重要的。
