Animals use some habitats and quit others. It is essential to examine resource which is of great interest to the animal for its survival. Distribution and habitat selection of Grey Francolin was examined in Swegali game reserve during June 2007. Twelve line transects 200 meters wide and average 3.73 kilometers long were laid down randomly for collection of data from 06h00-20h00 and observed 58 Grey francolins singly or in pairs. Distributed of Grey francolin was observed in three of the available six habitat types including woody ravines, shrub land and agricultural fields. Chi-squared test showed that Grey francolin displayed significant habitat selection and highly significant preference for woody ravines, northerly aspects and foraged in the morning and evening, a slight drag to the afternoon was also observed. The study can contribute to planning of management interventions for the study species and its preferred habitats. It might assist policy makers to devise policies pertaining to agriculture, study species and their habitats to mitigate encroachment into marginal lands for agriculture, human settlements, use of pesticides and unregulated hunting, assessment of the effects of resource use on wild populations, planning and policy decisions for habitat management and harvest levels.
动物使用一些栖息地,离开另一些。检查对动物的生存有重大意义的资源是必要的。2007年6月在瑞典野生动物保护区内调查了灰法兰克林的分布和生境选择。随机设置12条线样条,宽200米,平均长3.73公里,于6点至20点采集数据,对58只灰富兰克林进行了单独或成对的观测。在现有的6种生境类型中,有3种生境类型分别为林沟、灌丛地和农田。卡方检验表明,灰灰羊具有显著的生境选择性,对林木沟壑区、北侧具有高度显著的偏好,采食时间为早晚,下午采食时间也有轻微的延迟。该研究可为研究物种及其偏好栖息地的管理干预措施规划提供参考。它可以协助决策者制定有关农业的政策,研究物种及其生境以减轻对边缘土地的侵占,用于农业、人类住区、使用杀虫剂和不受管制的狩猎,评估资源使用对野生种群的影响,生境管理和收获水平的规划和政策决定。

Gomphotheres existed in the Siwaliks from the middle Miocene (14.2Ma) to the middle Pleistocene (0.8Ma) and became extinct later on. In this paper, we tried to discuss the reasons of such extinction of gomphotheres in the lower Pleistocene time span by considering Linear Enamel Hypoplasia (LEH) among 114 isolated tooth samples to assess whether ecological changes correlate with the stress factor in gomphotheres. For this purpose, the Siwalik gomphotheres were divided into two Groups viz. early gomphotheres (middle Miocene to late Miocene) and late gomphotheres (Pliocene to middle Pleistocene). We presented the hypothesis, that as the gomphotheres are characterized by the brachydonty and relied on browsing for their feeding while inhabiting the semi forest land setting thus, expected to have higher stress in Plio-Pleistocene time span as vegetational change around ~6 Ma may have exerted stress on late gomphotheres. The results for the occurrence of frequency of LEH indicated severe ecological stress in late gomphotheres (33%). The significant differences were found (P < 0.05) among the early gomphotheres and late gomphotheres which can be correlated to the vegetational change from C3 to C4, higher aridity indices and intensified seasonality after the late Miocene vegetational shift which may have resulted in substantial faunal turnover, extinction and speciation. We assume that such palaeoecological changes forced a competition with more pronounced grazers like of family Elephantidae and Bovidae resulting in extinction of gomphotheres during the late Pleistocene in the Siwaliks of Pakistan.
从中新世中期(14.2Ma)到更新世中期(0.8Ma),在Siwaliks中存在着gomphoiths,后来灭绝。本文通过对114个牙标本进行线性釉质发育不良(Linear珐琅质Hypoplasia, LEH)分析,探讨了牙象类在更新世晚期灭绝的原因,并探讨了生态变化是否与牙象类的应激因子有关。为此,将Siwalik象形虫划分为早期象形虫群(中中新世至晚中新世)和晚期象形虫群(上新世至中更新世)两个类群。我们提出假设,由于象形目以短齿动物为特征,在半森林环境中以觅食为食,因此,在上新世-更新世时期,象形目可能会受到更高的压力,因为~6 Ma左右的植被变化可能对后期象形目产生了压力。LEH发生频次的分析结果表明,龟类晚期的生态压力较大(33%)。早期和晚期gomphotha的差异显著(P < 0.05),这可能与中新世晚期植被转变后从C3到C4的植被变化、较高的干旱指数和强烈的季节性有关,这可能导致了大量的动物更替、灭绝和物种形成。我们假设这样的古生态变化迫使象科和牛科等更明显的食草动物与它们竞争,导致象科在巴基斯坦siwalik地区晚更新世灭绝。

Rose-ringed parakeet (P. krameri) is commonly found native psittacid in Pakistan. It is most popular companion bird in Pakistan. It is an unprotected species as per The Punjab Wildlife Act, 1974. The objectives of the present study were to study its population paradigm and basic nesting biology in the Gujar Khan, Punjab, Pakistan. Previously, no studies were carried out to assess its live and vacant nest cavities, nesting site, nest height, cavity position on substrate, and potential roosts in the area. Moreover, this study also assesses the potential threats and factors in this area and conservation of the parakeet. Results show that in the study area (36.77%) active and (63.22%) inactive nests were found. A total of 10 tree species were utilized to make nests. It was found Ficus bengalensis, Syzygium cumini, Morus alba, Melia azedarach and Broussonetia papyrifera as the most used tree species for nesting due to more frequencies and old ages. Parakeets make nest at 3-11 m height. The preferred nest height (42.48%) was in the range of 7-9 m, while (5.88%) least at 3-5 m height. For safety reasons they made more nests (45.09%) on the tree trunk followed by terminal (31.37%) and at fork (23.52%). Due to smaller thriving population we found only (mean=7±4) parakeets during roost counting. Severe cutting of trees, destruction of its habitat and poaching for selling in the bird market are the main causes of its population decline. Government must change its status from unprotected to protected species and should ban its dealing for pet.
玫瑰环长尾小鹦鹉(P. krameri)是巴基斯坦常见的原生鹦鹉。它是巴基斯坦最受欢迎的伴侣鸟。根据1974年《旁遮普野生动物法》,它是不受保护的物种。本研究的目的是研究其种群模式和基本筑巢生物学在巴基斯坦旁遮普省的古贾尔汗。在此之前,没有研究对其活巢和空巢、筑巢地点、巢高、巢在基质上的位置以及该地区的潜在栖息地进行评估。此外,本研究还评估了该地区的潜在威胁和因素以及对长尾小鹦鹉的保护。结果表明:研究区有活跃巢占36.77%,无活动巢占63.22%;共利用10种树种筑巢。榕树(Ficus bengalensis)、红树(Syzygium cumini)、桑树(Morus alba)、苦楝树(Melia azedarach)和纸莎草(Broussonetia papyrifera)是最常用的筑巢树种。长尾小鹦鹉在3-11米高的地方筑巢。42.48%的巢高在7 ~ 9 m, 5.88%的巢高在3 ~ 5 m。出于安全考虑,它们在树干上筑巢最多(45.09%),其次是终端(31.37%)和分叉(23.52%)。由于长尾小鹦鹉的数量较少,我们只发现(平均=7±4)只长尾小鹦鹉。严重砍伐树木,破坏其栖息地和偷猎在鸟类市场上出售是其数量下降的主要原因。政府必须将其从不受保护的物种改变为受保护的物种,并应禁止其宠物交易。

The Red fox (Vulpes vulpes) is a least concern carnivore according to the IUCN Red List of Threatened Species (2016). However, in Pakistan Red fox is considered as Near Threatened (NT), due to habitat destruction and depletion of food resources. The objective of the study was to identify habitat preferences and population density of Red fox in District Chakwal, Pakistan. Line transect census method was used to estimate the population density of Red fox through direct sighting and indirect method of burrow counting, presence of footprints and scats. A total of 10 transects were carried out at three potential sites: Devi, Photaki and Chumbisurla Wildlife Sanctuary (CWS) in Chakwal based on preliminary surveys. Habitat preference was estimated by comparing three different study sites by quadrat method and found that CWS area is preferred habitat for Red fox. A total of 24 plant species were recorded in the study areas, among them Cynodon dactylon is major herb found to provide shelter to Red fox in all study sites based on Importance value Index (I.V.I) at CWS (IVI=208.8) followed by Devi (IVI=185.93) and Photaki (IVI=142.33). The maximum population density of Red fox through direct sighting at CWS having 0.26 individuals/km2 compared to Devi and Photaki having 0.16 and 0.13 individuals/km2, respectively. The indirect estimation method revealed that maximum dens were found in CWS area compared to Devi and Photaki, while footprints and scats were found maximum in Devi and Photaki, respectively. It is concluded that Red fox preferred habitat is CWS site. Habitat destruction and conflicts with fox are causing the population of the Red fox to dwindle in Chakwal, Pakistan.
根据IUCN濒危物种红色名录(2016年),红狐是最不受关注的食肉动物。然而,在巴基斯坦,由于栖息地的破坏和食物资源的枯竭,红狐被认为是近危(NT)。本研究的目的是确定巴基斯坦Chakwal地区红狐的生境偏好和种群密度。采用样线普查法,通过直接观察和间接挖洞、足迹、粪便等方法估算红狐种群密度。在初步调查的基础上,在Chakwal的Devi, Photaki和Chumbisurla野生动物保护区(CWS)三个潜在地点共进行了10个样带。采用样方法对3个不同的研究点进行了生境偏好比较,发现红狐的首选栖息地为CWS区。研究区共记录到24种植物,其中Cynodon dactylon是各研究点为红狐提供庇护的主要草本植物(IVI=208.8),其次是Devi (IVI=185.93)和Photaki (IVI=142.33)。红狐在保护区直接观测的最大种群密度为0.26只/km2,而红狐和红狐分别为0.16只/km2和0.13只/km2。间接估算结果表明,CWS区洞穴数量最多,而Devi区和Photaki区足迹最多,Photaki区粪便最多。结果表明,红狐的首选栖息地为水煤浆区。在巴基斯坦的查克瓦尔,栖息地的破坏和与狐狸的冲突导致红狐的数量减少。

The freshwater algae grow in a wide range of aquatic habitats across the globe and are rich in secondary metabolites. The present study was designed to conduct the phytochemical screening, proximate analysis, antioxidant and antibacterial activities of water net (Hydrodictyon reticulatum), an algal weed from Pakistan. The pure and dried algal mass was crushed into a fine powder and four solvent-based extracts were used for phytochemical screening. The results of preliminary qualitative screening indicated the presence of flavonoids, phenols, quinones, steroids, resins, anthraquinones, glycosides, lignin, proteins, saponins, tannins, reducing sugars, alkaloids, terpenoids, fats, and oils, whereas the quantification results revealed the high quantities of total ash, crude proteins, crude fiber, alkaloids, carotenoids, flavonoids, and chlorophyll a. The studied methanolic extracts with maximum concentration (150 μg/ml) showed significantly (p-value ≤ 0.05) higher antioxidant and antibacterial activities. The IC50 values of the crude methanolic extract of water net were found very close to streptomycin (positive control) against both bacterial pathogenic species of Klebsiella pneumoniae and Staphylococcus aureus. This study concluded that the crude extracts of water net possessed antibacterial activity at par to streptomycin drug, and requires further detailed study for the separation, identification, and testing of the pure phytochemical compound to be used by the nutraceutical and or pharmaceutical industry.
淡水藻类生长在全球广泛的水生栖息地,富含次生代谢物。本研究旨在对巴基斯坦水藻(Hydrodictyon reticulatum)的植物化学筛选、近似分析、抗氧化和抗菌活性进行研究。将纯净和干燥的藻块粉碎成细粉,并使用四种溶剂基提取物进行植物化学筛选。初步定性筛选结果显示,黄酮类、酚类、醌类、甾体、树脂、蒽醌类、苷类、木质素、蛋白质、皂苷、单宁、还原糖、生物碱、萜类、脂肪和油脂含量较高,定量分析结果显示,总灰分、粗蛋白质、粗纤维、生物碱、类胡萝卜素、黄酮类、最大浓度为150 μg/ml的甲醇提取物具有显著(p值≤0.05)的抗氧化和抗菌活性。水网粗甲醇提取物对病原菌肺炎克雷伯菌和金黄色葡萄球菌的IC50值与阳性对照链霉素非常接近。本研究认为,水网粗提物具有与链霉素药物相当的抗菌活性,需要进一步详细的研究,以分离、鉴定和测试纯植物化学化合物,以供营养保健和/或制药行业使用。

The studied methanolic extracts with maximum concentration (150 μg/ml) showed significantly (p-value ≤ 0.05) higher antioxidant and antibacterial activities. The IC50 values of the crude methanolic extract of water net were found very close to streptomycin (positive control) against both bacterial pathogenic species of Klebsiella pneumoniae and Staphylococcus aureus. This study concluded that the crude extracts of water net possessed antibacterial activity at par to streptomycin drug, and requires further detailed study for the separation, identification, and testing of the pure phytochemical compound to be used by the nutraceutical and or pharmaceutical industry.","PeriodicalId":115980,"journal":{"name":"Journal of Bioresource Management","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124725574","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Water shortage is one of the major limiting factors of crop productivity worldwide. This study was planned to explore the impact of Capparis decidua stem extract on wheat varieties (FSD-2008, 12066 and 13348) under water stress condition. Water deficit condition negatively impacted the seedling germination, growth, photosynthetic pigments and ions uptake capacity. Water limited condition significantly (p≤0.05) increased time to attain 50% germination, lipid peroxidation, H2O2 and enhanced the antioxidant mechanism to overcome the oxidative stress. Different concentrations of C. decidua extract i.e. Not Soaking (NS), 10%, 20%, 30% and 40% were used for seed priming. It improved the negative effects of water stress and amended plant germination and growth by enhancing photosynthesis and reactive oxygen species (ROS) scavenging mechanism. The 20% and 30% C. decidua stem extract remained effective in mitigating the induced water stress effects in the tested cultivars. It was found that C. decidua stem extract significantly (p≤0.05) improved germination, growth Mg +2 and Fe +2 uptake in the wheat varieties under study. It is concluded that C. decidua phytoextract is an influential agent to ameliorate water stress effects in wheat at early growth stage.
水资源短缺是全球农作物产量的主要限制因素之一。本试验旨在探讨水分胁迫条件下,脱叶松茎提取物对小麦品种FSD-2008、12066和13348的影响。水分亏缺条件对幼苗萌发、生长、光合色素和离子吸收能力均有不利影响。限水条件显著(p≤0.05)提高了萌发达到50%的时间、脂质过氧化和H2O2,增强了抗氧化机制以克服氧化应激。采用不浸种、10%、20%、30%和40%不同浓度的松柏提取物进行催种。它通过增强光合作用和活性氧(ROS)清除机制,改善了水分胁迫的负面影响,改善了植物的萌发和生长。20%和30%落叶木茎提取物对不同品种的水分胁迫均有较好的缓解作用。结果表明,松柏茎提取物显著(p≤0.05)提高了小麦品种萌发、生长、Mg +2和Fe +2的吸收。综上所述,落叶木提取物是改善小麦生长早期水分胁迫效应的重要药剂。

A two years (2014-15 and 2015-16) field experiment was performed to find out the effect of plastic film and straw mulching on yield, water use efficiency (WUE) of wheat (Triticum aestivum L.) and selected soil properties. There were three treatments i.e. control, plastic film and straw mulch. No mulch was added in control. Rice straw was applied on the surface at a rate of 5 Mg ha-1. Soil samples in 0-15 cm and 15-30 cm depths were taken and analyzed. Soil water contents at 20 cm interval every 7 days were determined in 0-160 cm soil depth before sowing, after harvesting and during growing seasons. Results showed that grain yield was increased significantly by 29.8 in 2014-15 and 35.6% in 2015-16 over that of control under straw mulch. Straw mulch also decreased total water use with an increase in WUE. Soil bulk density was decreased significantly with a significant increase in porosity, water stable aggregates, active carbon, organic matter and soil water contents after harvesting. Soil water storage was higher under straw mulch for most sampling times. In conclusion, mulching soil with straw can sustain wheat yield and improve WUE and soil properties.
通过2014- 2015年和2015- 2016年2年的田间试验,研究了地膜和秸秆覆盖对小麦产量、水分利用效率(WUE)及部分土壤性状的影响。有三种处理,即防治、地膜和秸秆覆盖。控制组没有添加护根物。水稻秸秆按5 Mg ha-1施于表面。取0 ~ 15 cm和15 ~ 30 cm深度土壤样品进行分析。在播种前、收获后和生长季节分别测定0 ~ 160 cm土层含水量,间隔20 cm,每7 d测定一次。结果表明:2014-15年和2015-16年,秸秆覆盖可显著提高粮食产量,分别比对照提高29.8%和35.6%;秸秆覆盖也降低了水分利用总量,提高了水分利用效率。收获后土壤容重显著降低,孔隙度、水稳性团聚体、活性炭、有机质和土壤含水量显著增加。在大多数采样次数下,秸秆覆盖土壤储水量较高。综上所述,秸秆覆盖土壤可以维持小麦产量,提高水分利用效率和土壤性质。

Knowledge of soil properties is essential for environmental sustainability for any forest reserve or plantation. The physical and chemical properties of soil under three different land uses was investigated to assess the nutrient and fertility status of the soils. Fifteen soil samples, each collected from different locations within the natural forest, plantation and farm land were analyzed for soil texture, bulk density, porosity, pH, organic carbon, organic matter content, total nitrogen, available phosphorus, Na, K, Ca, Mg, Zn, Cu, Fe and Mn. Texturally, the soils were loamy, loamy sand and sandy loamy in the natural forest, plantation and farmland respectively. There was a significant difference between the three different soils in composition and texture.
