In this study, we present the description of a previously undocumented species of Cnemaspis found in the region of Tamil Nadu, India. Molecular analysis of the species reveals its placement within the Cnemaspis beddomei Theobald, 1876 clade, with a range of genetic divergence on the ND2 gene, spanning from 9.5% to 30.2% in comparison to its congeners. Although bearing a resemblance to the well-known Cnemaspis ornata Beddome, 1870, the new species exhibits a distinct set of non-overlapping morphological characteristics that set it apart. These findings are supported by molecular data, solidifying the distinction between the newly described species and its close relatives.
在这项研究中,我们介绍了在印度泰米尔纳德邦地区发现的一种以前未记载的cnmasis物种的描述。对该物种的分子分析表明,该物种属于1876年的beddomei Theobald线虫分支,其ND2基因的遗传差异范围为9.5%至30.2%。尽管与1870年发现的著名的Cnemaspis ornata Beddome有相似之处,但新物种表现出一套独特的非重叠形态特征,使其与众不同。这些发现得到了分子数据的支持,巩固了新描述的物种与其近亲之间的区别。

The Banteng (Bos Javanicus d'Alton 1823) is an endemic species in Indonesia that is threatened with extinction and whose population continues to decline in the wild. The aim of this study is to determine the timing of artificial insemination (AI) in the Banteng based on follicle size and uterine enlargement. For this study, two female Banteng were used in Taman Safari Indonesia, Cisarua, Bogor. Habituation was performed to facilitate data collection. Optimal timing for AI is determined by examining the reproductive organs using Ultrasonography (USG) to detect changes in the uterus and ovaries and monitor clinical signs of estrus. Follicle size and uterine examination was performed on days -1, 0, and +1 for 3 estrus cycles. Insemination was performed 2-3 times during estrus until ovulation occurred. The results showed that the average follicle size of both Banteng was 1.09 ± 0.02 cm on day -1, 1.31 ± 0.02 cm on day 0, and 1.33 ± 0.03 cm on day +1. Artificial insemination was performed with a double dose of frozen semen when the Banteng were still rideable, and the follicle size ranged from 1.23-1.38 cm. Pregnancy was examined by ultrasound on day 21 after mating; both Banteng females were pregnant after AI. It can be concluded that AI technique can be used in captive Banteng breeding program by studying the development of follicles and uterine enlargement.
班腾(Bos Javanicus d'Alton 1823)是印度尼西亚的一种特有物种,面临灭绝的威胁,其野生种群数量继续下降。本研究的目的是根据卵泡大小和子宫增大来确定班腾的人工授精(AI)时机。在这项研究中,两只雌性班腾在印度尼西亚的Taman野生动物园,Cisarua,茂物。进行习惯化以方便数据收集。人工授精的最佳时机是通过超声检查生殖器官(USG)来检测子宫和卵巢的变化,并监测发情的临床症状。在3个发情周期的第1、0、+1天进行卵泡大小和子宫检查。在发情期进行2-3次人工授精,直至排卵。结果表明,两种半藤的平均卵泡大小在第1天为1.09±0.02 cm,第0天为1.31±0.02 cm,第1天为1.33±0.03 cm。人工授精时,用双倍剂量的冷冻精液进行人工授精,其卵泡大小在1.23-1.38 cm之间。交配后第21天超声检查妊娠;在AI之后,两只班腾雌性都怀孕了。通过对卵泡发育和子宫增大的研究,认为人工智能技术可应用于圈养斑腾养殖计划。

Understanding and identifying butterfly species in various land uses serves a crucial eco-logical function in protecting biodiversity and improving environmental policy decisions. However, such a study on the diversity of butterflies from different land use types in and around Chebera Churchura Na-tional Park, southwestern Ethiopia, is extremely lacking. Thus, the present study aimed to quantify the species richness and abundance of butterflies in the Chebera Churchura National Park and its surroundings, which are prioritized for their conservation. Data was collected from January 2021 to June 2021 following the line transect method in the three habitat types using a standard insect net. In total, 2118 individuals representing 79 species and 38 genera belonging to five families were recorded. The Nymphalidae were the most dominant butterfly family, accounting for 45 species (57%) of the total butterflies observed, while the Heaspariidae contributed the least. Among the 79 species, 9 were very common, 32 were common, 37 were rare, and 1 was very rare. Based on butterfly species richness and composition, riverine forest had the greatest diversity and abundance with 65 species and 1028 individuals, and the least species composition was recorded in mosaic habitat with 26 species and 350 individuals, and the difference in diversity was significant. The study region was generally found to be rich in the diversity and abundance of butterflies in all three forms of land use. However, the study area is currently becoming an investment hub, and many road development projects are being planned. Ongoing human activities will devastate and harm the richness, abundance, and diversity of butterfly species. As a result, such human-induced activities need to be carefully studied to protect biodiversity.
了解和鉴定不同土地利用方式下的蝴蝶种类对保护生物多样性和改善环境决策具有重要的生态功能。然而,对埃塞俄比亚西南部Chebera Churchura国家公园及其周边不同土地利用类型的蝴蝶多样性的研究非常缺乏。因此,本研究旨在量化Chebera Churchura国家公园及其周边优先保护的蝴蝶物种丰富度和丰度。2021年1月至2021年6月,采用样线法对三种生境类型进行数据采集,使用标准虫网。共记录到5科38属79种2118只。蛱蝶科为优势科,共45种,占总数的57%;79种中,常见9种,常见32种,罕见37种,罕见1种。在蝴蝶种类丰富度和组成上,河流森林的蝴蝶种类最多,有65种,1028只;花叶生境的蝴蝶种类组成最少,有26种,350只,多样性差异显著。研究区在所有三种土地利用方式中均具有丰富的蝴蝶多样性和数量。然而,研究区域目前正在成为一个投资中心,许多道路发展项目正在规划中。持续的人类活动将破坏和损害蝴蝶物种的丰富性、丰富性和多样性。因此,需要仔细研究这种人为活动,以保护生物多样性。

Shyamlatal, a natural rain-fed wetland located at an elevation of 1300m in Champawat District, owes its prime conservation value in the Himalayan state of Uttarakhand, India. Because there is a scarcity of data on bio-resources that are critical to ecological functioning, the present study documented the species composition and seasonal patterns in richness and abundance of butterflies for their future management and conservation in a wetland environment of the Shyamlatal. A record of 64 species and 45 genera under six butterfly families was made from the catchment area of watershed and surrounding forests surveyed during 2016 to 2018. Nymphalidae with 28 species over 45.84% of the total individuals was the most dominant taxonomic group of butterflies. Species on conservation priority were rare (17.18% species), habitat specific (18.75% species), legally protected (7.81% species) and endemic (20.31% species) butterflies of the Himalaya. The overall species richness and diversity of butterflies varied across seasons and the high similarity in butterfly composition was observed during summer and autumn. Results provided baseline information on the importance of mosaic of vegetation in sustaining rich butterfly diversity around the wetland, which must be managed and conserved for maintaining ecological health and integrity of the region. The results also revealed that human activities have negative consequences on butterfly diversity in the study area.
Shyamlatal是一个位于Champawat区海拔1300米的天然雨水湿地,在喜马拉雅山脉的印度北阿坎德邦具有重要的保护价值。由于缺乏对生态功能至关重要的生物资源数据,本研究记录了蝴蝶的物种组成和丰富度和丰度的季节模式,以供其在Shyamlatal湿地环境中的未来管理和保护。在2016年至2018年期间调查的流域和周围森林的集水区中,记录了6个蝴蝶科下的64种45属。睡蝶科28种,占总个体的45.84%,是蝴蝶中最具优势的类群。优先保护的物种是喜马拉雅的稀有蝴蝶(17.18%)、特定栖息地蝴蝶(18.75%)、受法律保护蝴蝶(7.81%)和特有蝴蝶(20.31%)。蝴蝶的总体物种丰富度和多样性随季节而变化,在夏季和秋季观察到蝴蝶组成的高度相似性。结果提供了关于植被镶嵌在维持湿地周围丰富蝴蝶多样性方面的重要性的基线信息,必须对湿地进行管理和保护,以保持该地区的生态健康和完整性。研究结果还表明,人类活动对研究区域的蝴蝶多样性产生了负面影响。

, Lichens not only play a major role in plant succession as pioneer species but also provide many ecosystem services. Various anthropogenic activities like habitat destruction, air pollution and over exploitation of lichens for economic uses seem to be the main threats for loss of lichen diversity. Hence, for in situ conservation of lichens, it is a prioritised need to document lichen species of a locality. Lichens of Assam are being extensively studied from a taxonomic point of view in recent years. An accurate and updated checklist of lichens is not available so far. Here we expand the knowledge of the lichen of Assam by critically surveyed the literatures and prepared an updated list of total 657 species of Assam.
地衣不仅作为先锋物种在植物演替中起着重要作用,而且还提供多种生态系统服务。各种人为活动,如栖息地破坏、空气污染和为了经济用途而过度开采地衣,似乎是地衣多样性丧失的主要威胁。因此,对地衣的就地保护来说,记录地衣的种类是一个优先考虑的问题。近年来,人们从分类学的角度对阿萨姆邦地衣进行了广泛的研究。到目前为止,还没有一份准确和最新的地衣清单。在这里,我们通过批判性地调查文献,扩大阿萨姆邦地衣的知识,并准备了阿萨姆邦总共657种的更新清单。

The coral reef ecosystem in the Spermonde Archipelago manifests great potential in ecosystem services. However, it has been degraded to “severely damaged”. In this study we investigated the law enforcement related to coral reef conservation, especially the damage caused by destructive actions. We used mixed qualitative and quantitative methods. We explored existing laws, conductedsemi-structured interviewswith6 informants (five fishermen and one judge), collected data on regional convictions data,and surveyed 48 respondents with a quantitative questionnaire, in 5 sampling sites: South Galesong District, Takalar Regency; KodingarengLompo Island,Sangkarrang District Makassar city, Kapoposang Island; Sarappoand Papandangan Island; PangkajeneandKepulauan Regency. This study detected 26 destructive cases, in which the perpetrators were found guilty by the court with the consideration that their actions damaged the coral reef ecosystem. The perpetrators used bombs, cyanide, and cantrangnets to catch fish and collect corals for trading. The imposed sentence was mild and far from the maximum penalty, both in imprisonment and fine. Notably, none of the perpetrators were sentenced to half of the main legal threats. 96% of (n = 48) respondents in our study area disagreed with the mild penalty. A mild penalty may not provide deterrent effects to the perpetrators or others who have an intention to conduct similar activities.The questionnaire showed that most of the locals know about the conservation area (66%) and its regulation (88%). The best solution to strengthen the conservation effort is to quickly establish a fisheries court in Spermonde Archipelago, which is also supported by locals (92% agreed to the establishment). A fisheries court could examine, adjudicate, and decide fisheries criminal cases, such as illegal fishing and destructive fishing within their jurisdiction. The court could be established by Presidential Decree and it will be under supervision of the Supreme Court of Republic of Indonesia.
精子群岛的珊瑚礁生态系统在生态系统服务方面显示出巨大的潜力。然而,它已经退化为“严重损坏”。在这项研究中,我们调查了与珊瑚礁保护有关的执法情况,特别是破坏性行为造成的破坏。我们采用了定性和定量相结合的方法。我们探索了现有法律,对6名举报人(5名渔民和1名法官)进行了半结构化访谈,收集了地区定罪数据,并在5个采样点对48名受访者进行了定量问卷调查:南盖尔松区、塔卡拉县;KodingarengLompo岛,桑加朗区望加锡市,Kapoposang岛;Sarappond Papandangan岛;Pangkajen和Kepuluan摄政。这项研究发现了26起破坏性案件,其中犯罪者被法院认定有罪,因为他们的行为破坏了珊瑚礁生态系统。犯罪者使用炸弹、氰化物和大麻来捕鱼和收集珊瑚进行交易。判处的刑罚很轻,远未达到监禁和罚款的最高刑罚。值得注意的是,没有一名犯罪者被判处一半的主要法律威胁。在我们的研究区域,96%(n=48)的受访者不同意轻度处罚。轻微的处罚可能不会对犯罪者或有意进行类似活动的其他人产生威慑作用。调查问卷显示,大多数当地人了解保护区(66%)及其管理(88%)。加强保护工作的最佳解决方案是迅速在精子群岛建立一个渔业法庭,该法庭也得到了当地人的支持(92%的人同意建立)。渔业法院可以审查、裁决和裁决其管辖范围内的非法捕鱼和破坏性捕鱼等渔业刑事案件。该法院可根据总统令设立,并将接受印度尼西亚共和国最高法院的监督。

However, it has been degraded to “severely damaged”. In this study we investigated the law enforcement related to coral reef conservation, especially the damage caused by destructive actions. We used mixed qualitative and quantitative methods. We explored existing laws, conductedsemi-structured interviewswith6 informants (five fishermen and one judge), collected data on regional convictions data,and surveyed 48 respondents with a quantitative questionnaire, in 5 sampling sites: South Galesong District, Takalar Regency; KodingarengLompo Island,Sangkarrang District Makassar city, Kapoposang Island; Sarappoand Papandangan Island; PangkajeneandKepulauan Regency. This study detected 26 destructive cases, in which the perpetrators were found guilty by the court with the consideration that their actions damaged the coral reef ecosystem. The perpetrators used bombs, cyanide, and cantrangnets to catch fish and collect corals for trading. The imposed sentence was mild and far from the maximum penalty, both in imprisonment and fine. Notably, none of the perpetrators were sentenced to half of the main legal threats. 96% of (n = 48) respondents in our study area disagreed with the mild penalty. A mild penalty may not provide deterrent effects to the perpetrators or others who have an intention to conduct similar activities.The questionnaire showed that most of the locals know about the conservation area (66%) and its regulation (88%). The best solution to strengthen the conservation effort is to quickly establish a fisheries court in Spermonde Archipelago, which is also supported by locals (92% agreed to the establishment).

This survey reveals how the community in Rimbang Baling Wildlife Sanctuary in their understanding of positive laws, especially the state regulation, both concern the rule of law and laws related to conservation. In addition, their attitude towards sharia law such as the wildlife fatwa (MUI’s Fatwa No 4/2014) is about the protection of endangered wildlife to maintain ecosystem balance. We ask which rules must be obeyed first, the religious regulations, such as fatwas, or government rules? It has been revealed in this study that sharia complied with 20.1% (intervention villages = intervention) and 17.1% (control villages = control), government regulations of 15.3% (intervention), and 10.9% (control), while those who answered that both regulations must be obeyed were of 53.3% (intervention) and 65.1% (control), and the rest answered “don’t know”. The survey also questioned of hunting and trading of endangered animals prohibited by MUI Fatwa No. 4 of 2014. The respondents were on opinion that agreed and strongly agreed of 57.8% (intervention) and 65.1% (control), disagreed of 22.5% (intervention) and 21.7 (control), while the remainder was neutral, of 15.9% (intervention) and 10.9% (control). The results of relations of attitudes towards wildlife conservation between intentions and the resulting Spearman correlation values were of: p, 389 ** (control) and  p, 523 ** (intervention). This means that, for the control villages, the correlation of the two variables is suficien; on the other hand, the correlation in the intervention area has a strong value. The intervention areas, villages: Aur Kuning, Pangkalan Serai, Lubuk Bigau, and Kebun Tinggi, have relatively higher attitudes than the control villages, namely: Gajah Bertalut, Sungai Santi, Terusan, and Tanjung Permai.
本次调查揭示了林邦八陵野生动物保护区社区对实在法,特别是国家法规的理解,既涉及法治,也涉及保护相关法律。此外,他们对伊斯兰教法的态度,如野生动物法特瓦(MUI的法特瓦第4/2014号)是关于保护濒危野生动物以维持生态系统平衡。我们问必须首先遵守哪些规则,是宗教法规,如fatwas,还是政府规则?本研究发现,伊斯兰教法遵守政府规定的比例分别为20.1%(干预村=干预)和17.1%(对照村=对照),政府规定遵守的比例分别为15.3%(干预村)和10.9%(对照村),而回答必须遵守这两项规定的比例分别为53.3%(干预村)和65.1%(对照村),其余回答为“不知道”。调查还对MUI 2014年第4号法特瓦禁止的濒危动物的狩猎和交易提出了质疑。57.8%(干预组)和65.1%(对照组)的受访者表示同意和非常同意,22.5%(干预组)和21.7%(对照组)的受访者表示不同意,15.9%(干预组)和10.9%(对照组)的受访者表示中立。野生动物保护态度意向与Spearman相关值的关系结果分别为:p, 389 **(对照)和p, 523 **(干预)。这意味着,对于对照村,这两个变量的相关性是充分的;另一方面,干预区域的相关性具有很强的价值。干预区:Aur Kuning村、Pangkalan Serai村、Lubuk Bigau村和Kebun Tinggi村的态度相对高于对照村:Gajah Bertalut村、Sungai Santi村、Terusan村和Tanjung Permai村。
