“…Although A . occidentalis have small home ranges (median range between 1.57 ha– 1.79 ha, [ 64 ]) and rely on low quality abundant leaves, suggesting that they would be able to inhabit relatively small fragments, it is possible that the number and distribution of large trees impacts Avahi occurrence [ 63 ]. Norscia [ 63 ] found that the percentage of large trees above 3.2 cm DBH was significantly positively related to Avahi density.…”

Determining what factors affect species occurrence is vital to the study of primate biogeography. We investigated the metapopulation dynamics of a lemur community consisting of eight species (Avahi occidentalis, Propithecus coquereli, Microcebus murinus, Microcebus ravelobensis, Lepilemur edwardsi, Cheirogaleus medius, Eulemur mongoz, and Eulemur fulvus) within fragmented tropical dry deciduous forest habitat in Ankarafantsika National Park, Madagascar. We measured fragment size and isolation of 42 fragments of forest ranging in size from 0.23 to 117.7 ha adjacent to continuous forest. Between June and November 2011, we conducted 1218 surveys and observed six of eight lemur species (M. murinus, M. ravelobensis, C. medius, E. fulvus, P. coquereli, and L. edwardsi) in the 42 fragments. We applied among patch incidence function models (IFMs) with various measures of dispersal and a mainland-island IFM to lemur species occurrence, with the aim of answering the following questions: 1) Do lemur species in dry deciduous forest fragments form metapopulations? 2) What are the separate effects of area (extinction risk) and connectivity/isolation (colonization potential) within a lemur metapopulation? 3) Within simulated metapopulations over time, how do area and connectivity/isolation affect occurrence? and 4) What are the conservation implications of our findings? We found that M. murinus formed either a mainland-island or an among patch metapopulation, M. ravelobensis formed a mainland-island metapopulation, C. medius and E. fulvus formed among patch metapopulations, and neither P. coquereli or L. edwardsi formed a metapopulation. Metapopulation dynamics and simulations suggest that area was a more consistent positive factor determining lemur species occurrence than fragment isolation and is crucial to the maintenance of lemur populations within this fragmented landscape. Using a metapopulation approach to lemur biogeography is critical for understanding how lemur species respond to forest loss and fragmentation.

“…Species‐specific contact calls may facilitate efficient group travel or foraging, maintain group cohesion, update group members to individual statuses of constituent group members, orient the motivational status of the group as a whole (e.g., female is still hungry, so the pair should keep traveling to access a new food patch), and coordinate behaviors (Cheney & Seyfarth, 2018; Ramanankirahina, Joly, Scheumann, & Zimmermann, 2016; Teixeira da Cunha & Byrne, 2009). Many species retain close spatial proximity with pair‐mates through nearly constant contact call use, which may be particularly useful during reduced visibility (e.g., during nocturnal foraging bouts in P. pallescens ; Kappeler, 1997).…”

Only a handful of primate species exhibit the social relationship of pair‐bonding. Efficient communication is critical for behavioral coordination within pair‐bonds to maintain proximity and respond appropriately to extra‐pair individuals, and possibly coordinate infant care. The use of complex signaling across modalities may help individuals improve communicative outcomes. We review many ways that pair‐bonded species use signals to communicate and maintain bonds, though little previous research has taken a truly multimodal approach within a single species. We make a call for further investigation into pair‐bonded communication using a multimodal approach to better understand how these species use all their senses to build, maintain, and advertise their bonds.

“…In many mammalian species vocal communication is essential to coordinate social interactions such as mating rituals (e.g., [ 1 , 2 ]), alarm calling (e.g., [ 3 , 4 ]), mother-infant care (e.g., [ 5 , 6 ]), group cohesion (e.g., [ 7 , 8 ]), or territorial displays (e.g., [ 9 , 10 ]). One of the first steps towards understanding the complexity of acoustic communication in a given species is to establish a vocal repertoire [ 11 ].…”

Describing vocal repertoires represents an essential step towards gaining an overview about the complexity of acoustic communication in a given species. The analysis of infant vocalisations is essential for understanding the development and usage of species-specific vocalisations, but is often underrepresented, especially in species with long inter-birth intervals such as the white rhinoceros. Thus, this study aimed for the first time to characterise the infant and juvenile vocal repertoire of the Southern white rhinoceros and to relate these findings to the adult vocal repertoire. The behaviour of seven mother-reared white rhinoceros calves (two males, five females) and one hand-reared calf (male), ranging from one month to four years, was simultaneously audio and video-taped at three zoos. Normally reared infants and juveniles uttered four discriminable call types (Whine, Snort, Threat, and Pant) that were produced in different behavioural contexts. All call types were also uttered by the hand-reared calf. Call rates of Whines, but not of the other call types, decreased with age. These findings provide the first evidence that infant and juvenile rhinoceros utter specific call types in distinct contexts, even if they grow up with limited social interaction with conspecifics. By comparing our findings with the current literature on vocalisations of adult white rhinoceros and other solitary rhinoceros species, we discuss to which extent differences in the social lifestyle across species affect acoustic communication in mammals.
