Abstract. The objective of this study was to clarify ecological factors influencing winter field sign abundance of Korean water deer Hydropotes inermis argyropus in a temperate forest on Mt. Maehwa, Hongcheon, South Korea. There were significant differences in four variables of cover and three variables of forage between the different topographic features, part from the midstory vegetation coverage. Most of the winter field signs of Korean water deer were observed on the ridge. The abundance of feces and total field signs of Korean water deer varied considerably between the topographical features. The understory vegetation, midstory vegetation, forb and shrub coverage, topography, understory vegetation × topography, midstory vegetation × topography, and shrub × topography were higher value of relative variable importance among habitat variables. Understory and midstory vegetation coverage, forage and topography were important ecological factors for affecting winter field sign abundance of Korean water deer.

Abstract. Research that elucidates the differences in the habitat use and diet of sympatric species is essential and meaningful for protection strategies. The habitat use and diet composition of blue sheep (Pseudois nayaur) and Alashan red deer (Cervus alashanicus) in the Helan Mountains, China, were examined from November 2013 to February 2015. Despite the partial overlap in habitat, the habitat used by blue sheep and Alashan red deer were significantly different. Blue sheep preferred mountain woodland steppe with high degree of slope at farther distances from water resources and bare rock. Alashan red deer selected winter habitat in moutain grassland with flat slopes, closer water resources, further distances to human disturbances and bare rock. The diet of blue sheep was significantly different from that of Alashan red deer regarding the proportions of the forage categories. Blue sheep grazed primarily on shrubs (36.7 %) and grass (23.1 %), while the diet of Alashan red deer was dominated by shrubs (43.6 %) and trees (25.6 %). Contrary to Alashan red deer, blue sheep preferred to forage on herbaceous plants.

Abstract. Food preferences of the edible dormouse were revealed with the use of radio-tracking. Studies were conducted on two plots in July and August of two years: one year with good beech (Fagus sylvatica) mast and the second with poor beech mast. Study plots were located in Roztocze National Park (RNP) where beech constituted about 80 % of the tree stand) and in Sieraków Landscape Park (SLP) where beech formed about 30 % of the tree stand. Six individuals (three males, three females) were radio-tracked in both years on each plot. Every animal was radio-tracked during four nights by using continuous recording during which the duration of foraging on particular tree species was recorded. On both study plots, the dormice foraged mostly on the common beech, eating both ripe fruit, ripening fruit and vegetative parts of trees. In a beech mast year, on both study plots, the animals foraged on the beech (both July and August) and on the fir Abies alba in RNP and on the common hazel Corylus avellana in SLP (in August). Bigger differences in diets between the two populations studied were found in a non-mast year, resulting from differential foraging and exploitation of subdominant tree and bush species on the plots. The dormice foraged mostly on food that was characterized by the highest nutritional value at a given time.

Abstract. Within a conifer plantation, hazel dormice (Muscardinus avellanarius) were individually marked from 2000 to 2016. In four adjacent experimental study areas (ESAs) of 3 ha each, a different method of restoration of a Planted Ancient Woodland Site (PAWS) was carried out in autumn 2003 to remove ca. 33 % of conifers. A third of those left were removed in 2009 and in 2015. The effects on dormouse abundance indices were recorded by routine monitoring of nest boxes, including marking individuals. The overall number of dormouse captures varied from year to year, increasing the year following forestry operations in 2003 and 2009, possibly because nest boxes temporarily became more attractive. The numbers of individually marked adults showed a stable trend but less variation. The numbers of small juveniles recorded appears to be rising in recent years, suggesting a positive impact during the later stages of this conifer forest reversion. The overwinter survival index of marked juveniles fell significantly for those born the year after each forest operation but not those alive when the felling took place. Adult survival did not fall in either year. Initially, dormouse populations were sustained in each ESA after management and the numbers were not significantly different between the treatments. After the 2009 operation dormouse numbers fell significantly in the traditional mechanical area-wide forest thinning treatment and low abundance has continued. This study demonstrating maintenance of a population of a European Protected Species has important implications for managers and we suggest similar forest management considerations are incorporated into policy and best practice guidelines. The results so far suggest that a patchwork regime type of conifer removal regime can be chosen to be both pragmatic for an economic forestry business and ensuring dormice remain in the local forest.

All of us who knew Rod Baxter were shaken by the news of his sudden death on 17 October 2015. Although Rod had entered the community of the “Dormousers” (specialists studying dormice and regularly communicating in meetings) late in his career, he played a prominent role in research on Southern African small mammal biology, ever since his studies at the University of Natal (South Africa) in the 1970s. Roderick Murray Baxter was born on 27 August 1951 in Irene near Pretoria, Union of South Africa (now Republic of South Africa), to Patricia and Murray F. Baxter. His father was head of medical research at the Counsel for Scientific and Industrial Research. The family has resided in South Africa since the 19th century. During the Anglo-Boer War, Rod’s great uncle Jack Baxter was executed by British troops for wearing a khaki suit, which was illegal lest for British soldiers. This tragic incident had left bitter resentment in Rod against British colonialists. Rod had spent his youth together with two brothers and one sister in an arid region, and frequently evoked his early experience of struggling with drought. He went to school in Irene and in Lyttelton (both Gauteng Province, South Africa). In the 1970s he joined the University of Natal in Pietermaritzburg and started his professional career as research assistant of Waldo Meester, studying, at that time, less known small mammals. Although the title at first had sounded impressive to a young postgraduate, the workload was high and the salary was low. Besides, there was a generation gap between these two men. While Waldo Meester, an internationally recognized authority on the taxonomy of African mammals, had based his works on museum vouchers, Rod, just like the majority of other junior staff, had nursed interest on behaviour and was desperate to work with living animals. His colleagues remember Rod as a bright, intelligent, and dynamic young man with a wide interest and true passion, particularly for his beloved and “favourite” mammals: Shrews. His enquiring mind and his excellent powers of observation were equally admired as was his empathy and compassion for his fellows. Caring about others, offering help and time lending an ear or even two to his students who sometimes had private, social, or family problems had top priority throughout his many years working with students and colleagues. At that time, Rod had long hair, a beard, and enjoyed smoking a pipe – he liked the smell of tobacco. He was not the only smoker among the University staff and in those days when people were still allowed to smoke inside, the smell of tobacco had filled the zoology department. After receiving his Master’s degree, he stayed in Pietermaritzburg for a short time before he joined the University of Cape Town. Thereafter, in 1983, he started lecturing at the University of Fort Hare, Alice, Eastern Cape Province, living in King Williams Town and later in Grahamstown together with his wife Ann, which meant long daily driv
我们所有认识Rod Baxter的人都对他于2015年10月17日突然去世的消息感到震惊。尽管罗德在职业生涯的后期进入了“睡鼠”(研究睡鼠并定期在会议上交流的专家)的圈子，但自从20世纪70年代在纳塔尔大学(南非)学习以来，他在南部非洲小型哺乳动物生物学的研究中发挥了突出作用。1951年8月27日，罗德里克·默里·巴克斯特出生于南非联邦(现南非共和国)比勒陀利亚附近的艾琳，母亲是帕特里夏·巴克斯特和默里·f·巴克斯特。他的父亲是科学和工业研究顾问的医学研究主管。这个家族自19世纪以来一直居住在南非。在英布战争期间，罗德的伯父杰克·巴克斯特(Jack Baxter)因穿着卡其色西装而被英军处决，这对英国士兵来说是非法的。这一悲惨事件使罗德对英国殖民者产生了强烈的怨恨。罗德与两个兄弟和一个妹妹一起在干旱地区度过了他的青年时代，他经常回忆起他早年与干旱作斗争的经历。他在Irene和Lyttelton(都是南非豪登省)上学。20世纪70年代，他加入了彼得马里茨堡的纳塔尔大学，开始了他的职业生涯，担任沃尔多·梅斯特的研究助理，研究当时不太为人所知的小型哺乳动物。虽然这个头衔一开始对一个年轻的研究生来说很有吸引力，但工作量大，薪水低。此外，这两个人之间有代沟。当国际公认的非洲哺乳动物分类学权威沃尔多·梅斯特(Waldo Meester)根据博物馆的代金券完成他的工作时，罗德和大多数其他初级职员一样，对行为产生了兴趣，并迫切希望与活的动物一起工作。在同事们的记忆中，罗德是一个聪明、聪明、充满活力的年轻人，兴趣广泛，充满激情，尤其是对他心爱的、“最喜欢的”哺乳动物:鼩鼱。他的探究精神和卓越的观察力，以及他对同伴的同情和同情，同样令人钦佩。在他与学生和同事的多年工作中，关心他人、提供帮助和时间——倾听甚至倾听有时有私人、社会或家庭问题的学生——是他的首要任务。那时，罗德留着长发，留着胡子，喜欢抽烟斗——他喜欢烟草的味道。他并不是大学里唯一一个吸烟的人。在那个允许在室内吸烟的年代，整个动物学系都弥漫着烟草的气味。在获得硕士学位后，他在彼得马里茨堡呆了很短的一段时间，然后加入了开普敦大学。此后，1983年，他开始在东开普省爱丽丝市的黑尔堡大学(Fort Hare University)讲课，住在金威廉姆斯镇(King Williams Town)，后来和妻子安(Ann)一起住在格雷厄姆斯敦(Grahamstown)，这意味着每天开车上下班要花很长时间。2008年，他们搬到了佛罗里达州的文达。- 67 (2): 120-127 (2018) DOI: 1.25225 /fozo.v67.i2.a8.2018

Abstract. Here, we report the values of 13 haematological parameters obtained from 10 potentially reproductive female individuals of the edible dormouse (Glis glis) from anthropogenically uninfluenced deciduous woodlands of Colchisian-Mediterranean type, with evergreen colchisine sub-forest in the Strandja region of Northeastern Thrace (Bulgaria). All specimens were captured at the end of the spring season in the bird's nest box in which they had lived. Values of hematological parameters investigated were calculated using a non-parametric percentile method and are described by their basic descriptive statistics (Mean; Median; SD; 2.5, 25, 75 and 97.5 percentile values). The present examination and statistical analysis of the hematological parameters described has established the basic norm of their variation in this species, described by their 2.5-97.5 % percentile range. This can be used not only for evaluation of the physiological condition of individuals, but also as an informative marker for evaluating the quality of the natural environment which they inhabit and thus contributes to species conservation in the Southeast Balkans.

Abstract. Age-related variation in breeding performance is well-known in birds. Similarly, plumage ornamentation as a signal of male quality may affect breeding performance. However, because of inter-correlation between age and plumage ornamentation, it is difficult to estimate the relative contribution of these factors on breeding performance in natural variation. In the current study, we examined the relationship between breeding characteristics, age and throat ornament size of bluethroat males (Luscinia s. svecica). The study was conducted on 96 males in the Krkonoše Mountains, Czech Republic, in 2003-2011. The results show that older males had higher reproductive performance: they arrived earlier, were more likely to be territorial, had larger clutches and thus had more hatchlings. On the other hand, ornamentation had a few, inconsistent correlations with breeding performances: well-ornamented males had fewer mates but had more fledglings. Our results suggest that age rather than ornamentation size is the main correlate of variation in breeding performance.

Abstract. A feral population of edible dormice (Glis glis) has been monitored by examining a network of 230 nest boxes placed ca. 25 m apart within a 100 ha wood in southern England. Individuals have been microchipped as juveniles or adults to subsequently determine various parameters during their lifetime. Evidence from microchipping records indicated that most individuals were recorded in summer in one or very few adjacent nest boxes during their known lifespan – even for individuals recorded over ten years old. During most years between 2009 to 2016 radio collars were fitted in the autumn to a small sample of microchipped adult individuals. These adults were located periodically if possible using radio telemetry to determine the exact location of their winter hibernaculum. The distances and direction from the known nest boxes used were very variable. Some individual hibernacula were also successfully excavated to provide further information. The data are analysed and discussed in the context of preparing control operations where Glis are a pest in houses or woods.

A feral population of edible dormice (Glis glis) has been monitored by examining a network of 230 nest boxes placed ca. 25 m apart within a 100 ha wood in southern England. Individuals have been microchipped as juveniles or adults to subsequently determine various parameters during their lifetime. Evidence from microchipping records indicated that most individuals were recorded in summer in one or very few adjacent nest boxes during their known lifespan – even for individuals recorded over ten years old. During most years between 2009 to 2016 radio collars were fitted in the autumn to a small sample of microchipped adult individuals. These adults were located periodically if possible using radio telemetry to determine the exact location of their winter hibernaculum. The distances and direction from the known nest boxes used were very variable. Some individual hibernacula were also successfully excavated to provide further information. The data are analysed and discussed in the context of preparing control operations where Glis are a pest in houses or woods.","PeriodicalId":50436,"journal":{"name":"Folia Zoologica","volume":"51 1","pages":"91 - 97"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88418523","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. Facing the ongoing decline in garden dormice (Eliomys quercinus) in large parts of Europe, data about genetic diversity, weight, size, and parasite burden were collected from live individuals (n = 156) from Hesse and Rhineland-Palatinate, Germany. Blood was collected under Isoflurane-oxygen-anaesthesia from the anterior vena cava or jugular vein, respectively. Sex, weight, tibiotarsal and tail length of all animals were recorded. Genetic analysis (n = 64) using hair samples, viral examinations of oral, ocular and anal swabs (n = 156) and parasitological examination of faecal samples (n = 57) were performed. Genetic analysis of mitochondrial DNA revealed three haplotypes in the study area (WE4, WE4-3, WE5). Microsatellite analysis demonstrated a comparably high genetic diversity with 66 % overlap of alleles, a low genetic distance (DJost 5.6 %) and a low index of differentiation (FST = 0.02) between individuals from Hesse and Rhineland-Palatinate. All swab samples were negative for Borna disease virus. In 47 % of the faecal samples Entamoeba sp. cysts, Eimeria sp. oocysts, and eggs of trematodes, cestodes (Hymenolepis spp.) and nematodes (Capillaria spp., Strongylida) were detected. To our knowledge, this is the first report of inhalation anaesthesia, clinical examination, blood collection and assessment of Borna disease virus in living garden dormice.

Abstract. Major roads are commonly regarded as migration barriers for most terrestrial animal species. Hazel dormouse, Muscardinus avellanarius, populations in south-eastern Schleswig-Holstein were investigated in order to assess the possible effects of major roads on their genetic variability and genetic structure. A total of 177 samples were collected and analysed, using ten microsatellite loci. Estimates of genetic diversity (expected heterozygosity: 0.48-0.65, allelic richness: 2.9-3.9) were within the range commonly found in this species. No evidence of inbreeding or past bottlenecks was detected. The software structure grouped the samples into five subpopulations. However, this subdivision should be treated with caution, since many individuals with mixed or unclear genetic profiles were found, possibly representing migrants or their offspring. Contrary to the previous assumption that dormice hardly ever cross roads, the present study shows that dormice not only cross even major roads, but also hold close relationships to individuals living on the other side of the motorway. The high number of animals captured within a small area and the relatively low genetic differentiation (FST: 0.142 and 0.105) despite the great distances (33.1 and 25.6 km) along the road, indicate that the roadside shrubs can actually be good habitats for dormice and provide suitable corridors for migration.
