Nocturnal primates have large vocal repertoires. This suggests that acoustic communication plays an important role in their life histories. Little is known about the behavioural context or the intraspecific variation of their vocalisations. We used autonomous recording units and manual recorders to investigate the vocal behaviour and structure of loud calls of the small-eared greater galago (Otolemur garnettii)in Kenya and Tanzania. We describe the vocal repertoire, temporal calling patterns and structure of 2 loud calls of 2 subspecies: O. g. panganiensis and O. g. kikuyuensis. We found considerable intraspecific structural differences in both loud calls. These are congruent with the current subspecies classification. Differences in vocalisations among populations are not consistent with the “acoustic adaptation hypothesis,” rather they are likely a result of geographic variation due to isolation caused by vegetational barriers in southern Kenya.","PeriodicalId":50437,"journal":{"name":"Folia Primatologica","volume":"90 1","pages":"319 - 335"},"PeriodicalIF":1.9,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1159/000500260","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44941582","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite this, primate vocal repertoires often also include gradations between different call types that are used in social interactions. Because many nocturnal primates show a solitary social structure, it has been difficult to assess the role vocalisations play in mediating their social encounters. Here we aim to expand on the call types of Sahamalaza sportive lemurs, Lepilemur sahamalaza, as well as investigate their variability and use in social contexts. Through long-term behavioural observations with concurrent recording of vocalisations of known and unknown individuals between 2015 and 2016, we described three previously unrecorded calls and expanded the vocal repertoire to 12 different call types that were used in both targeted social and broadcast solitary contexts. Linear discriminant function and cluster analysis supported initial observations that vocalisations within call types were variable and that at least two call types can be classified as “graded,” contrary to expectations. Despite variations in call-context connections, no clear patterns of call use could be established. However, measurable differences in vocal behaviour between the seasons and the sexes indicate that calling is used in a reproductive context, similar to other nocturnal and diurnal primates.","PeriodicalId":50437,"journal":{"name":"Folia Primatologica","volume":"90 1","pages":"336 - 360"},"PeriodicalIF":1.9,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1159/000493939","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48531603","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent taxonomic work has disentangled some of the confusion. This has resulted in an increase in the number of recognised galago species. The most widespread galago species, and indeed the most widespread nocturnal primate, is the northern lesser galago (Galago senegalensis) whose geographic range stretches >7,000 km across Africa. Based on morphology, 4 subspecies are currently recognised: G. s. senegalensis, G. s. braccatus, G. s. sotikae and G. s. dunni. We explore geographic and subspecific acoustic variation in G. senegalensis, testing three hypotheses: isolation by distance, genetic basis, and isolation by barrier. There is statistical support for isolation by distance for 2 of 4 call parameters (fundamental frequency and unit length). Geographic distance explains a moderate amount of the acoustic variation. Discriminant function analysis provides some degree of separation of geographic regions and subspecies, but the percentage of misdesignation is high. Despite having (putative) parapatric geographic ranges, the most pronounced acoustic differences are between G. s. senegalensis and G. s. dunni. The findings suggest that the Eastern Rift Valley and Niger River are significant barriers for G. senegalensis. The acoustic structures of the loud calls of 121 individuals from 28 widespread sites are not significantly different. Although this makes it unlikely that additional unrecognised species occur within G. senegalensis at the sites sampled, vast areas of the geographic range remain unsampled. We show that wide-ranging species do not necessarily exhibit large amounts of variation in their vocal repertoire. This pattern may also be present in nocturnal primates with smaller geographic ranges.","PeriodicalId":50437,"journal":{"name":"Folia Primatologica","volume":"90 1","pages":"300 - 318"},"PeriodicalIF":1.9,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1159/000499654","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48655254","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The use of vocalisations as a primary mode of communication has been the focus of much research, especially in attempts to understand the origins of human language, with a major focus on anthropoid primates and diurnal lemurs. Over the last decade, technological advances have allowed researchers to begin to conduct in-depth investigations into the communication systems exhibited by the nocturnal and cathemeral prosimian primates, including tarsiers, lemurs and lorises. Understanding how nocturnal prosimians use visual, olfactory and auditory cues is vital for reconstructing the origins of primate communication systems. In this special issue, we highlight some of the more exciting advances in the communication strategies of the prosimians. Contributions come from work conducted in Kenya, Tanzania, Senegal, Rwanda, Madagascar and the Indonesian islands of Java and Sulawesi. Topics will include: the description of novel ultrasonic vocalisations, including frequency and function of these newly discovered calls; the possible use of vocalisations to navigate and assemble at sleep sites; the importance of species-specific contact vocalisations for the identification of new species; the use of urinary and glandular signals to communicate and the methods developed to understand this complex communication in the field; the use of vocalisations for niche separation among nocturnal primates from mainland Africa and Madagascar; and whether or not we can use new technologies to discern whether prosimians use vocalisations for individual identification of group members. We discuss the importance of new field methods including novel equipment and techniques, the use of vocalisation to influence conservation practices and the importance of comparing across prosimian taxa to reconstruct the communication systems of our early primate ancestors.","PeriodicalId":50437,"journal":{"name":"Folia Primatologica","volume":"90 1","pages":"273 - 278"},"PeriodicalIF":1.9,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1159/000501003","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45172905","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Species are the fundamental unit of study in phylogeny, behaviour, ecology and conservation. Identifying species boundaries is particularly challenging for nocturnal taxa where only subtle morphological variation is present. Traditionally, vocal signals have been used to identify species within nocturnal primates: species-specific signals often play a critical role in mate recognition, and they can restrict gene flow with other species. However, little research has been conducted to test whether different “acoustic forms” also represent genetically distinct species. Here, we investigate species boundaries between two putative highly cryptic species of Eastern dwarf galagos (Paragalago cocosand P. zanzibaricus). We combined vocal and genetic data: molecular data included the complete mitochondrial cytochrome b gene (1,140 bp) for 50 samples across 11 localities in Kenya and Tanzania, while vocal data comprised 221 vocalisations recorded across 8 localities. Acoustic analyses showed a high level of correct assignation to the putative species (approx. 90%), while genetic analyses identified two separate clades at the mitochondrial level. We conclude that P. cocos and P. zanzibaricus represent two valid cryptic species that probably underwent speciation in the Late Pliocene while fragmented in isolated populations in the eastern forests.","PeriodicalId":50437,"journal":{"name":"Folia Primatologica","volume":"90 1","pages":"279 - 299"},"PeriodicalIF":1.9,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1159/000496972","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48248880","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because high-frequency sounds are capable of travelling only short distances, their function is limited by the distance the sound can be discerned. One possible function for these short-distance, high-frequency sounds is that they might be used by the tarsiers to navigate throughout their environment. I conducted this study at Tangkoko Nature Reserve in Sulawesi, Indonesia, from May to August 2017. Using the focal follows, I recorded the start of each locomotor activity to the nearest second. I also simultaneously recorded all ultrasonic vocalisations that the focal individual emitted using a Wildlife Acoustics Ultrasonic Song Meter BAT3. Approximately 42% of the ultrasonic calls that I recorded during this study were given within 1 s prior to engaging in locomotor activity. The tarsiers gave statistically more ultrasonic calls during locomotion than during other behaviours (rest, forage and social). Four types of ultrasonic calls were given while locomoting: whistles, doubles, trills and frequency-modulated calls. Of these, the trill and the frequency-modulated call were only given during locomotion, and trills were only given prior to leaping. These results preliminarily suggest that the tarsiers do use ultrasonic calls for navigation. Studying echolocation in organisms closely related to bats is critical for understanding the evolution of echolocation.","PeriodicalId":50437,"journal":{"name":"Folia Primatologica","volume":"90 1","pages":"379 - 391"},"PeriodicalIF":1.9,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1159/000497811","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43144807","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
