The alarm vocalizations of the whistling rats Parotomys brantsii and P. littledalei were investigated at the Goegap Nature Reserve in the Northern Cape, South Africa, where they occur sympatrically. Parotomys brantsii's call is a single note vocalization, characterized by an upward frequency sweep and high frequency plateau with a dominant frequency of 10.0 ± 0.3 kHz and duration of 164 ± 11 ms. The alarm whistle of P. littledalei has three overlapping components and is both shorter (53 ± 5 ms…

The effect of body size and habitat on the evolution of alarm vocalizations in rodents
TLDR
The results of the present study show that the acoustic frequencies of alarm calls can provide reliable information about the size of a sender in this taxonomic group, although they generally do not support the acoustic adaptation hypothesis.
Call divergence in three sympatric Rattus species.
To reduce errors in species recognition and the probability of interbreeding that lowers fitness, individuals within sympatric zones shift the signals to differentiate from those of other species. In…
Acoustic analysis of the alarm call of the Anatolian ground squirrel Spermophilus xanthoprymnus: a description and comparison with alarm calls of the Taurus S. taurensis and European S. citellus ground squirrels
TLDR
A description of the acoustic structure of alarm call of the Anatolian ground squirrel S. xanthoprymnus is provided and it is found that these three species can be clearly distinguished on the basis of their alarm calls.
Geographic variability in the alarm calls of the European ground squirrel
TLDR
There is a rather substantial geographic variability in the alarm calls of the European ground squirrel, and this study highlights its possible impact on conservation measures such as establishing artificial colonies or reintroductions.
Reduced geographic variation in roars in different habitats rejects the acoustic adaptation hypothesis in the black‐and‐gold howler monkey ( Alouatta caraya )
TLDR
The combination of high amplitude and low peak frequency of roars, coupled to small home range size and extensive overlap between neighboring groups, allows roars to keep their communication value across habitats without need of specific environmental tuning.
Low Geographic and Subspecific Variation in the Loud Call of the Widespread and Phenotypically Cryptic Northern Lesser Galago (Galago senegalensis) Suggests Taxonomic Uniformity
TLDR
It is suggested that the Eastern Rift Valley and Niger River are significant barriers for G. senegalensis, and wide-ranging species do not necessarily exhibit large amounts of variation in their vocal repertoire, which may also be present in nocturnal primates with smaller geographic ranges.
Song variation and habitat structure in the Golden Bowerbird
TLDR
It is suggested that local habitat structure has relatively little effect on the design of acoustic signal in the Golden Bowerbird at the individual level, while efficiency of transmission may influence signal design on evolutionary time-frames.
Associated tympanic bullar and cochlear hypertrophy define adaptations to true deserts in African gerbils and laminate‐toothed rats (Muridae: Gerbillinae and Murinae)
TLDR
It is concluded that in both arid and semi‐arid adapted laminate‐toothed rats and gerbils there is bulla and associated cochlea hypertrophy, particularly in true desert species.
Chapter 2 The Micaelamys namaquensis ( Rodentia : Muridae ) species complex from southern Africa : Patterns of mitochondrial DNA versus morphological diversity
  • Biology
  • 2012
TLDR
The genetic differentiation among populations of the Namaqua rock mouse, Micaelamys namaquensis Smith, 1834 a murine rodent from southern Africa, is reported, based on mitochondrial DNA (mtDNA) cytochrome b (cyt b) sequences.
Howl variation across Himalayan, North African, Indian, and Holarctic wolf clades: tracing divergence in the world’s oldest wolf lineages using acoustics
TLDR
The results suggest that genetic divergence and/or geographic distance may play an important role in understanding howl variation across subspecies.

Variation of the Chip Vocalization of Three Species of Townsend Chipmunks (Genus Eutamias)
TLDR
Examination of alarm calls in these three Eutamias taxa support their recognition as distinct species and suggest that one particular population of chipmunks from northern California and Oregon may contain hybrid individuals.
The social organization and breeding system of Brants' whistling rat (Parotomys brantsii)
TLDR
There was, however, evidence that reproductively receptive females were more tolerant of males, who may guard females following mating, which parallels the scramble competition polygyny described for a number of other species, including North American ground squirrels.
Pattern Analysis of Acoustical Behavior in Four Species of Ground Squirrels
TLDR
Chirp calls seemed to be convergent where species were sympatric while churr calls seemed unaffected, and cluster analysis of call syllable patterns determined both within-call structure, and phenetic relationships between species.
Adaptation to living in an open arid environment: lessons from the burrow structure of the two southern African whistling rats, Parotomys brantsii and P. littledalei
This study examines interspecific differences in the architecture and field characteristics of the burrow systems of Brants' whistling rat, Parotomys brantsii, and Littledale's whistling rat,…
Associations of Song Properties with Habitats for Territorial Oscine Birds of Eastern North America
  • R. H. Wiley

  • 1991
TLDR
The results suggest that the temporal properties of songs of many oscines have evolved to reduce the effects of reverberation in forested habitats, and Exceptional species might have retained features of song subject to degradation to permit listeners to judge distances to singers.
Yellow-bellied marmot and golden-mantled ground squirrel responses to heterospecific alarm calls

  • 1998
TLDR
Results indicate that both marmots and squirrels recognized not only their own species' anti-predator vocalizations, but also the alarm calls of another species, and that these vocalizations were discriminated from an equally loud non-threatening sound.

Geographical Variation in the Song of the Great Tit (Parus major) in Relation to Ecological Factors
TLDR
It is concluded that differences between habitats in climate, body size, perch height, and acoustic competition from other species are unimiportant in accounting for the observed differences in song.

The Role of Body Size, Phylogeny, and Ambient Noise in the Evolution of Bird Song
TLDR
There has been an evolutionary response to selection for low-frequency songs by birds in low-forest habitats, according to the constraints of body size and evolutionary history, and the spectral distribution of ambient noise as an additional selective factor is examined.
