The African golden cat Caracal aurata (Temminck, 1827) is an IUCN Red List ‘Vulnerable’ species (Bahaa-el-din et al., 2015b) and is considered Africa’s least known felid (Bahaa-eldin et al., 2015a). This species is restricted to forested habitats in equatorial Africa, with Kenya at the eastern limit of the species’ distribution (Butynski et al., 2012; Ray & Butynski, 2013). The status of C. aurata in Kenya remains unknown. Until now, the only confirmed records are two skins collected by A. Toschi in 1946 from Ogiek tribesmen in the Mau Forest (Toschi, 1946; Butynski et al., 2012). One of the skins (Accession No. 3369/332A) is currently at the National Museums of Kenya (NMK). All other records from the country are sight records that lack a supporting photograph or specimen (Butynski et al., 2012). On 19 May 2019, a dead cat, presumably killed by a vehicle, was found beside the section of the Kamae-Thika road that bisects the Kieni Forest Reserve in the southern Aberdares (0°52'12.9144"S and 36°45'05.4684"E; figure 1). It was immediately identified as a possible C. aurata and taken to NMK (Accession No. NMK-MAM-192942). Upon inspection of the specimen, and in consultation with experts in the field (L. Bahaa-el-din (pers. comm.); T.M. Butynski (pers. comm,); D. Mills (pers. comm.)), the specimen was confirmed to be a C. aurata. This is the first confirmed record of C. aurata for Kenya since 1946, and the first record of this species east of the Eastern Rift Valley. This specimen was collected ~2300 m above sea level in Afromontane forest at the edge of the bamboo zone. It was a female of the golden/reddish-brown morph (Bahaa-el-din et al., 2015a; figure 2) with the following weight and body measurements: weight: 3.1 kg, headbody length: 60 cm, and tail length: 26.5 cm.

非洲金猫Caracal aurata (Temminck, 1827)是世界自然保护联盟红色名录“脆弱”物种(Bahaa-el-din et al., 2015b),被认为是非洲最不为人知的猫科动物(Bahaa-eldin et al., 2015a)。该物种局限于赤道非洲的森林栖息地,肯尼亚是该物种分布的东部极限(Butynski et al., 2012;Ray & Butynski, 2013)。C. aurata在肯尼亚的状况尚不清楚。到目前为止,唯一确认的记录是A. Toschi于1946年从茂森林的Ogiek部落收集的两张皮(Toschi, 1946;Butynski et al., 2012)。其中一张皮(登记号3369/332A)目前在肯尼亚国家博物馆(NMK)。来自该国的所有其他记录都是缺乏支持照片或标本的视觉记录(Butynski et al., 2012)。2019年5月19日,在阿伯达尔南部(南纬0°52'12.9144"和东经36°45'05.4684")的凯马-西卡公路(Kamae-Thika road)路段旁发现了一只死猫,可能是被车辆撞死的;图1)。立即鉴定为可能的C. aurata,并将其带到NMK (Accession No. 1)。nmk -妈- 192942)。在检查了标本后,并与该领域的专家进行了磋商(L. Bahaa-el-din)。通讯);丁恩斯基(p。通讯,);D.米尔斯(pers)(通讯)),标本被确认为C. aurata。这是自1946年以来肯尼亚首次确认的aurata记录,也是该物种在东非大裂谷以东的首次记录。本标本采自海拔2300 m左右的非洲山林竹林边缘地带。它是一只金黄色/红棕色的雌性(Bahaa-el-din et al., 2015;图2)体重和体型:体重:3.1公斤,头身长:60厘米,尾长:26.5厘米。这个标本看起来像是一只大小猫或一只

ABSTRACT The minute, cleptoparasitic bee genus Chiasmognathus (Nomadinae: Ammobatini) is documented from western Kenya, representing the southernmost records of the lineage. Two species are recognized from the Great Rift Valley—Chiasmognathus aturksvenicus, from the southwestern side of Lake Turkana, and the other, C. riftensis, from further south near Lake Bogoria. The former was captured in association with its host, Nomioides (Nomioides) turanicus (Halictinae: Nomioidini). Chiasmognathus saheliensis is considered a new junior synonym of Pasites gnomus, and the latter epithet is transferred to Chiasmognathus: C. gnomus. We illustrate and discuss intraspecific variation in some morphological features of these tiny bees.
来自肯尼亚西部的微小寄生蜂属Chiasmognathus (Nomadinae: Ammobatini)被记录,代表了该谱系最南端的记录。大裂谷发现了两个物种——来自图尔卡纳湖西南侧的chiasmognathus aturksvenicus,另一个是来自更南边的Bogoria湖附近的C. riftensis。前者是与其寄主野蝇(Nomioides) turanicus (Halictinae: Nomioidini)联合捕获的。Chiasmognathus saheliensis被认为是Pasites gnomus的一个新的初级同义词,后者的绰号被转移到Chiasmognathus: C. gnomus。我们说明和讨论在这些小蜜蜂的一些形态特征种内变异。

ABSTRACT The Sokoke dog or bushy-tailed mongoose Bdeogale omnivora is poorly known and considered to be endemic to the East African coastal forests. Systematic camera trap surveys, comprising 9229 camera trap days on grids at six study sites, were used to determine the distribution and relative abundance of the Sokoke bushy-tailed mongoose in the two largest Kenyan coastal forests: Boni-Dodori Forest Complex (ca. 4000 km2); and Arabuko-Sokoke Forest Reserve (416 km2). This species was captured in all surveyed forests with significantly more detections in Brachystegia woodland habitat (ca. 71 km2) of Arabuko-Sokoke and the Boni forest sectors (ca. 2000 km2) of the Boni-Dodori Forest Complex. Boni-Dodori Forest Complex, with an estimated occupancy of over 60% for this species, holds a significant population. The study generated over 1000 images of the Sokoke bushy-tailed mongoose in a total surveyed area of approximately 500 km2 providing the first 24-hour activity data for the species. The circadian patterns confirm this species to be strictly nocturnal. This study strongly recommends that its Red List status remains ‘Vulnerable’. The few remaining coastal forests continue to face human pressure. Recent proposals to find and extract hydrocarbons from under the Arabuko-Sokoke Forest, and the planned major development close to Boni-Dodori Forest Complex, raise serious conservation concerns for this exceptionally biodiverse ecosystem.
杂食性猫鼬(Sokoke dog或budeogale mongoose)为人所知甚少,被认为是东非沿海森林的特有物种。系统的相机陷阱调查,包括在六个研究地点的9229个相机陷阱日,用于确定肯尼亚两个最大的沿海森林中的Sokoke浓密尾猫鼬的分布和相对丰度:Boni-Dodori森林群(约4000平方公里);Arabuko-Sokoke森林保护区(416平方公里)。该物种在所有调查的森林中均有捕获,其中在Arabuko-Sokoke的Brachystegia林地栖息地(约71 km2)和Boni- dodori森林复合体的Boni森林区(约2000 km2)有较多的发现。Boni-Dodori森林综合体,估计占该物种的60%以上,拥有大量的人口。该研究在大约500平方公里的总调查区域内生成了1000多张Sokoke浓密尾猫鼬的图像,提供了该物种的第一个24小时活动数据。昼夜节律模式证实这个物种是严格的夜行动物。这项研究强烈建议它的红色名录地位仍然是“脆弱的”。仅存的少数沿海森林继续面临人类的压力。最近在Arabuko-Sokoke森林下寻找和提取碳氢化合物的建议,以及计划在博尼-多多利森林综合体附近进行的主要开发,引起了对这一生物多样性异常丰富的生态系统的严重关注。

ABSTRACT Although African crested porcupines Hystrix spp. represent 0.5–34% of lion Panthera leo kills, interactions between the two species are poorly documented. Here we review porcupine-lion interactions and their impact on lion behaviour, including: 1) lion predation on porcupines; 2) lions injured or killed by porcupine quills; and 3) a case of a lion severely injured by a porcupine quill. Porcupine quills can be effective weapons and sometimes seriously wound lions, resulting in death. Death from quills can be a slow process and under these circumstances, death may be the result of starvation or infection (septicaemia).
尽管非洲冠毛豪猪Hystrix spp.占狮子Panthera leo捕杀量的0.5-34%,但这两个物种之间的相互作用却鲜有文献记载。本文综述了豪猪与狮子的相互作用及其对狮子行为的影响,包括:1)狮子捕食豪猪;2)被豪猪刺伤或杀死的狮子;3)一只狮子被豪猪的羽毛刺严重伤害的案例。豪猪的刺是有效的武器,有时会严重伤害狮子,导致死亡。刺死可能是一个缓慢的过程,在这种情况下,死亡可能是饥饿或感染(败血症)的结果。

ABSTRACT Comparative behavioural research reveals both intra- and inter-species diversity among primates. Few long-term behavioural studies have been conducted on African nocturnal primates. Here we describe and compare behavioural and ecological observations on two species of pottos (Perodicticus ibeanus and P. edwardsi) across ten sites. We observed a total of 51 P. edwardsi and 28 P. ibeanus. We recorded all 21 postures within an established lorisid ethogram, as well as 42 of 50 behaviours. Eating, locomotion, freezing, resting and sniffing were the most common behaviours. We recorded behaviours not previously described for perodicticines, including bark chewing and unique vocalisations. Three species of pottos are now recognised, with potentially more species to be revealed within this cryptic and nocturnal genus. Although there are similarities among potto species, we show that unique ecological adaptations and behaviours may further elucidate their diversity.
比较行为学研究揭示了灵长类动物种内和种间的多样性。对非洲夜行灵长类动物进行的长期行为研究很少。在这里,我们描述并比较了在十个地点对两种马铃薯(Perodicticus ibeanus和P. edwardsi)的行为和生态观察。我们一共观察到51只edward P.和28只ibeanus P.。我们记录了所有21种姿势和50种行为中的42种。进食、运动、冻结、休息和嗅闻是最常见的行为。我们记录了以前没有在期刊中描述的行为,包括树皮咀嚼和独特的发声。现在已经确认了三种马铃薯,在这个神秘的夜间植物属中可能会发现更多的物种。尽管盆栽物种之间存在相似性,但我们表明独特的生态适应和行为可能进一步阐明它们的多样性。

ABSTRACT Two populations of Meruterrana elegans, a monotypic bush-cricket genus, endemic to Mount Kenya in Kenya were surveyed. The species is restricted to Cassipourea forest, a forest community vanishing rapidly on Mount Kenya and with it Meruterrana elegans, which therefore should be included to the IUCN red list of threatened species as Critically Endangered.
摘要对肯尼亚肯尼亚山特有的一种单型灌木蟋蟀(Meruterrana elegans)进行了调查。该物种仅限于cassiourea森林,这是一个在肯尼亚山迅速消失的森林群落,因此应该将其列入世界自然保护联盟濒危物种红色名录,即极度濒危物种。

ABSTRACT Maned rat Lophiomys imhausi is a highly unusual, but very little known rodent that is endemic to East Africa. A population from the highlands of central Kenya was studied through analysis of owl pellets and prey remains, including one incidental observation. Over 28 months, 40 individual rats were documented, of which two were juveniles. The mean length of time between discovery of rat remains in any one owl territory was once every 5.3 months, and the maximum number of rats found in any single owl territory over one year was five. Maned rat density was low and was estimated at 1 rat/km2. Their lower altitudinal limit in Kenya is c. 1900 m, and eagle owls and humans are important predators. Maned rats are not uncommon in highly altered habitats and they may require poisonous plants in addition to Acokanthera spp. for anti-predator defense.
毛鼠(Lophiomys imhausi)是一种非常罕见但鲜为人知的东非特有啮齿动物。通过分析猫头鹰的颗粒和猎物遗骸,包括一次偶然的观察,研究了肯尼亚中部高地的一个种群。在28个月的时间里,记录了40只老鼠,其中两只是幼鼠。在任何一个猫头鹰领地发现老鼠遗骸的平均时间间隔是每5.3个月一次,在任何一个猫头鹰领地发现的老鼠的最多数量是一年5只。毛鼠密度低,估计为1只/km2。它们在肯尼亚的海拔下限约为1900米,鹰、猫头鹰和人类是重要的捕食者。鬃鼠在高度改变的栖息地并不罕见,它们可能需要有毒的植物来抵御捕食者。

Maned rats are not uncommon in highly altered habitats and they may require poisonous plants in addition to Acokanthera spp. for anti-predator defense.","PeriodicalId":143820,"journal":{"name":"Journal of East African Natural History","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133856275","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}

ABSTRACT During my studies of primate behavioral ecology in the Kibale Forest, Uganda, I documented the first cases of red-capped robin-chats Cossypha natalensis imitating an antiphonal duet. In one case two individual robin chats imitated the entire duet of the black-faced rufous warbler Bathmocercus rufus, each giving both the male and female components. In a second case one robin chat gave the male components and another gave that of the female warbler. The lack of temporal separation between the male and female components of the warbler's antiphonal duet indicates an unusually high level of auditory perception and response time and cognitive ability on the part of redcapped robin-chats.
在对乌干达基巴莱森林灵长类动物行为生态学的研究中,我首次记录了红帽知更鸟模仿对唱二重唱的案例。在一个案例中,两只知更鸟模仿了黑脸棕尾莺的整个二重唱,每只知更鸟都有雄性和雌性的成分。在第二种情况下,一只知更鸟给了雄性莺的成分,另一只给了雌性莺的成分。在莺的对唱二重唱中,雄性和雌性成分之间缺乏时间分离,这表明红冠知更鸟的听觉感知、反应时间和认知能力异常高。

The Reptiles of the Uzungwa Scarp Forest Reserve (User): An Updated Checklist with Notes on Dagger-Tooth Vine Snake Xyelodontophis uluguruensis Uzungwa悬崖森林保护区的爬行动物(用户):匕首牙藤蛇Xyelodontophis uluguruensis的更新清单和注释

ABSTRACT Uzungwa Scarp Forest Reserve (USFR) is one of the largest continuous forests within the Eastern Arc Mountains that has not been surveyed adequately from a herpetological perspective. A herpetological survey was carried out in the USFR at the beginning of the wet season, from December 2014 to February 2015. Bucket pitfall traps, night surveys and opportunistic search methods were conducted in six sites. Of 21 reptile species recorded during the survey, five are reported for the first time in the USFR. The checklist of reptiles for the area is updated from thirty three to thirty eight species. The study also provided notes on reproduction and extension in distribution for Xyelodontophis uluguruensis, a snake that was only discovered in 2002 and is known to be restricted to the Uluguru, Nguru and Mahenge mountains. These findings add to the conservation importance of the USFR and calls for more long term surveys especially in the least explored areas.
乌津古瓦断崖森林保护区(USFR)是东弧山脉最大的连续森林之一,但尚未从爬行动物的角度进行充分的调查。在2014年12月至2015年2月雨季开始时,在USFR开展了一项爬行动物调查。在六个地点进行了水桶陷阱、夜间调查和机会搜索方法。在调查中记录的21种爬行动物中,有5种是首次在USFR报告的。该地区的爬行动物清单从33种更新到38种。该研究还提供了关于Xyelodontophis uluguruensis的繁殖和扩展分布的记录,这种蛇是2002年才发现的,已知仅限于Uluguru, Nguru和Mahenge山脉。这些发现增加了保护USFR的重要性,并呼吁进行更多的长期调查,特别是在探索最少的地区。
