Records of the Malayan porcupine, Hystrix brachyura (Mammalia: Rodentia: Hystricidae) in Singapore.

NATURE IN SINGAPORE 9: 63–68.

Abstract:

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.

UL HASAN, M. A. & NEHA, S. A. (2019)

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.4861.11.12.14624-14626.

Auszug:

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

Abstract:

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).

PATTERSON, B. D. & NORRIS, R. W. (2016)

Towards a uniform nomenclature for ground squirrels: the status of the Holarctic chipmunks.

Mammalia 2016; 80(3): 241–251.

Abstract:

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.

SPOTORNO, A. E. & PATTON, J. L. (2015)

Superfamily Chinchilloidea Bennett, 1833.

In: PATTON, J. L., PARDIÑAS, U. F. J. & D'ELÍA (Hrsg.) Mammals of South America. Vol. 2, Rodents: 762-782. University of Chicago Press.

Buchinhalt:

The second installment in a planned three-volume series, this book provides the first substantive review of South American rodents published in over fifty years. Increases in the reach of field research and the variety of field survey methods, the introduction of bioinformatics, and the explosion of molecular-based genetic methodologies have all contributed to the revision of many phylogenetic relationships and to a doubling of the recognized diversity of South American rodents. The largest and most diverse mammalian order on Earth—and an increasingly threatened one—Rodentia is also of great ecological importance, and Rodents is both a timely and exhaustive reference on these ubiquitous creatures.

From spiny mice and guinea pigs to the oversized capybara, this book covers all native rodents of South America, the continental islands of Trinidad and Tobago, and the Caribbean Netherlands off the Venezuelan coast. It includes identification keys and descriptions of all genera and species; comments on distribution; maps of localities; discussions of subspecies; and summaries of natural, taxonomic, and nomenclatural history. Rodents also contains a detailed list of cited literature and a separate gazetteer based on confirmed identifications from museum vouchers and the published literature.

Rusa unicolor (Artiodactyla: Cervidae).

Mammalian Species, 43(1):1-30 (2011). https://doi.org/10.1644/871.1.

Volltext (Website)

Abstract:

Rusa unicolor (Kerr, 1792), or sambar, is the largest Oriental deer. Seven subspecies occur in varied habitats and elevations from India and Sri Lanka throughout southeastern Asia. Body mass and antler length decrease from west to east. R. unicolor is considered ancestral relative to the form of its male-only antlers and social behavior. Populations are vulnerable because of overexploitation for subsistence and markets in meat and antlers. R. unicolor was elevated by the International Union for Conservation of Nature and Natural Resources from no status in 2006 to “Vulnerable” in 2008 because of >50% decline in many populations over the past 3 generations. It is well represented in zoos and private collections and is introduced in Australia, New Zealand, South Africa, and the United States.
