Gibbon Systematics and Species Identification.
International Zoo News 42(8): 467-501.
A study of wild and captive gibbons and museum specimens, and a survey of the literature suggests that gibbons (genus Hylobates) include at least 11, possibly 12 species, which form 4 distinct groups (subgenera Hylobates, Bunopithecus, Nomascus, and Symphalangus): These are the 44-chromosome gibbons (including the Hylobates lar group and H. klossii: 5 species); the hoolock ( H. hoolock, 1 species); the H. concolor group (3, possibly 4 species); and the siamang ( H. syndactylus, 1 species). A key for the identification of adult gibbons based on visual characteristics is presented, together with colour photographs and distribution maps of all recognised species (11). In addition, diagnostic vocal characteristics of all species are described and illustrated with sonagrams.
Mixed herds of Common and Defassa waterbuck, Kobus ellipsiprymnus (Artiodactyla: Bovidae), in northern Kenya.
Bonn. zool. Beitr. 37(3): 183-193.
Observations of two mixed herds of Common and Defassa Waterhuck with potential hybrids of the two forms in Buffalo Springs Game Reserve, northern Kenya, are reported. Current theories published in the literature as to the distributional history and taxonomic status of the two forms are discussed.
Die Beobachtung von 2 gemischten Herden mit Ellipsen- und Defassa-Wasserböcken und möglichen Hybriden zwischen beiden Formen in Buffalo Springs Game Reserve, N-Kenia, ist Anlaß für eine Diskussion der in der Literatur publizierten Vorstellungen zu ihrer Verbreitungsgeschichte und zu ihrem taxonomischen Status.
Notes on Gessner’s Giraffe. Bible, Sources and Iconography.
In Leu, U. B. & Optiz, P.: Conrad Gessner. Die Renaissance der Wissenschaften. De Gruyter Oldenbourg; De Gruyter, pp.557-579, 2019, 978-3-11-049696-3. 10.1515/9783110499056-030. hal-02139257
The chapter on giraffe given by Conrad Gessner in his Historia animalium1 is an important step in the long-term history of this animal, from Antiquity to pre-modern times.2 The aim of this paper is not to give an in-depth review of Gessner’s chapter on the giraffe, but it will stress three topics: the specific problem of the presence of the giraffe in the Bible; some aspects of Gessner’s textual sources, with a special focus on medieval authors, and the illustrations of the giraffe in the printed editions of Gessner’s Historia animalium.

Records of the Malayan porcupine, Hystrix brachyura (Mammalia: Rodentia: Hystricidae) in Singapore.
NATURE IN SINGAPORE 9: 63–68.
The Malayan porcupine (Hystrix brachyura) is known to be native to Singapore, but the lack of sightings from 1970‒2000 suggested that the species was either locally rare or extinct. With the widespread use of camera traps in wildlife monitoring projects since 2005, there have been a substantial number of records involving porcupines which are compiled here. The conservation status of Hystrix brachyura in Singapore is briefly discussed.
The Himalayan Crestless Porcupine Hystrix brachyura Linnaeus, 1758 (Mammalia: Rodentia: Hystricidae): first authentic record from Bangladesh.
Journal of Threatened Taxa 11(12):14624-14626. DOI:10.11609/jott.48220.127.116.1124-14626.
During our social survey in Sundarbans mangrove forest, Bangladesh, the Hystrix brachyura was sighted in the Supoti Forest Camp (22.0470N & 89.8270E), Sundarbans East Zone, Bangladesh. On 22 May 2018, opportunistically an individual of porcupine was directly spotted but it was soon fled away into the shrubs and unidentified at that moment. The observation area was dominated by Acanthus ilicifolius and Phragmites karka. To substantiate the confirmation, a subsequent attempt was taken on 24 May 2018. Though several studies have revealed that various kinds of bait lured to particular species in general, or attract more of a prescribed species has been of specific focus; considering the facts, pieces of apples and potatoes were used to attract porcupine in a suitable place where a clear observation could be made. One more time, an individual attracted to bait was seen under the shrub of Phragmites karka at 19.35h. Finally, a clear visual observation as well as several photographs were taken. We recorded the geographic coordination using Garmin GPSMAP 64S.
How many species of mammals are there?
Journal of Mammalogy 99 ( 1): 1–14, doi.org/10.1093/jmammal/gyx147
Accurate taxonomy is central to the study of biological diversity, as it provides the needed evolutionary framework for taxon sampling and interpreting results. While the number of recognized species in the class Mammalia has increased through time, tabulation of those increases has relied on the sporadic release of revisionary compendia like the Mammal Species of the World (MSW) series. Here, we present the Mammal Diversity Database (MDD), a digital, publically accessible, and updateable list of all mammalian species, now available online: https://mammaldiversity.org. The MDD will continue to be updated as manuscripts describing new species and higher taxonomic changes are released. Starting from the baseline of the 3rd edition of MSW (MSW3), we performed a review of taxonomic changes published since 2004 and digitally linked species names to their original descriptions and subsequent revisionary articles in an interactive, hierarchical database. We found 6,495 species of currently recognized mammals (96 recently extinct, 6,399 extant), compared to 5,416 in MSW3 (75 extinct, 5,341 extant)—an increase of 1,079 species in about 13 years, including 11 species newly described as having gone extinct in the last 500 years. We tabulate 1,251 new species recognitions, at least 172 unions, and multiple major, higher-level changes, including an additional 88 genera (1,314 now, compared to 1,226 in MSW3) and 14 newly recognized families (167 compared to 153). Analyses of the description of new species through time and across biogeographic regions show a long-term global rate of ~25 species recognized per year, with the Neotropics as the overall most species-dense biogeographic region for mammals, followed closely by the Afrotropics. The MDD provides the mammalogical community with an updateable online database of taxonomic changes, joining digital efforts already established for amphibians (AmphibiaWeb, AMNH’s Amphibian Species of the World), birds (e.g., Avibase, IOC World Bird List, HBW Alive), non-avian reptiles (The Reptile Database), and fish (e.g., FishBase, Catalog of Fishes).
Towards a uniform nomenclature for ground squirrels: the status of the Holarctic chipmunks.
Mammalia 2016; 80(3): 241–251.
The chipmunks are a Holarctic group of ground squirrels currently allocated to the genus Tamias within the tribe Marmotini (Rodentia: Sciuridae). Cranial, postcranial, and genital morphology, cytogenetics, and genetics each separate them into three distinctive and monophyletic lineages now treated as subgenera. These groups are found in eastern North America, western North America, and Asia, respectively. However, available genetic data (mainly from mitochondrial cytochrome b) demonstrate that the chipmunk lineages diverged early in the evolution of the Marmotini, well before various widely accepted genera of marmotine ground squirrels. Comparisons of genetic distances also indicate that the chipmunk lineages are as or more distinctive from one another as are most ground squirrel genera. Chipmunk fossils were present in the late Oligocene of North America and shortly afterwards in Asia, prior to the main radiation of Holarctic ground squirrels. Because they are coordinate in morphological, genetic, and chronologic terms with ground squirrel genera, the three chipmunk lineages should be recognized as three distinct genera, namely, Tamias Illiger, 1811, Eutamias Trouessart, 1880, and Neotamias A. H. Howell, 1929. Each is unambiguously diagnosable on the basis of cranial, post-cranial, and external morphology.
