Validation of Cercopithecus erythrogaster pococki as the name for the Nigerian white-throated guenon.

Mammalia 63 (3): 389-392.

Zusammenfassung:

Die Autoren validieren den Nemen Cercopithecus erythrogaster pococki für die nigerianische Unterart der Rotbauchmeerkatze. Der Name Cercopithecus pococki war von John Guy DOLLMAN im frühen 20. Jahrhundert eingeführt worden, allerdings ohne dass dieser die Form beschrieben hätte. 1927 wurde der Name publiziert, jedoch nicht in einer Form, dass er nach den taxonomischen Regeln "verfügbar" gewesen wäre. Dies wurde von den Autoren 1999 nachgeholt.

Biogeography of the marmosets and tamarins (Callitrichidae).

Mol Phylogenet Evol. 2015 Jan; 82 Pt B: 413-25. doi: 10.1016/j.ympev.2014.04.031. Epub 2014 May 20.

Abstract:

The marmosets and tamarins, Family Callitrichidae, are Neotropical primates with over 60 species and subspecies that inhabit much of South America. Although callitrichids exhibit a remarkable widespread distribution, attempts to unravel their biogeographic history have been limited by taxonomic confusion and the lack of an appropriate statistical biogeographic framework. Here, we construct a time-calibrated multi-locus phylogeny from GenBank data and the callitrichid literature for 38 taxa. We use this framework to conduct statistical biogeographic analyses of callitrichids using BioGeoBEARS. The DIVAj model is the best supported reconstruction of biogeographic history among our analyses and suggests that the most recent common ancestor to the callitrichids was widespread across forested regions c. 14 Ma. There is also support for multiple colonizations of the Atlantic forest region from the Amazon basin, first by Leontopithecus c. 11 Ma and later by Callithrix c. 5 Ma. Our results show support for a 9 million year old split between a small-bodied group and large-bodied group of tamarins. These phylogenetic data, in concert with the consistent difference in body size between the two groups and geographical patterns (small-bodied tamarins and large-bodied tamarins have an unusually high degree of geographic overlap for congeners) lend support to our suggestion to split Saguinus into two genera, and we propose the use of distinct generic names; Leontocebus and Saguinus, respectively.

WEHAUSEN, J. D., RAMEY, R. R. (2000)

Cranial morphometric and evolutionary relationships in the northern range of Ovis canadensis.

J. of Mammalogy, 81(1):145-161 (2000). https://doi.org/10.1644/1545-1542(2000)081<0145:CMAERI>2.0.CO;2

Abstract:

Univariate and multivariate statistical methods were used to examine geographic variation in skull and horn characters of 694 bighorn sheep (Ovis canadensis) specimens from the Great Basin north to British Columbia and Alberta to test previous taxonomic hypotheses. Substantially more morphometric variation in skull and horn size and shape was found west of the Rocky Mountains than within the Rocky Mountains. Our results did not support the recognition of Audubon's bighorn sheep (O. c. auduboni) as a subspecies separate from Rocky Mountain bighorn sheep (O. c. canadensis). California bighorn sheep (O. c. californiana) from Washington and British Columbia were not distinguishable from Rocky Mountain bighorn sheep but differed notably from populations in the Sierra Nevada considered part of that subspecies. Extirpated native populations from northeastern California, Oregon, and southwestern Idaho, also considered to be O. c. californiana, shared with Nelson bighorn sheep (O. c. nelsoni) from the Great Basin desert a horn-related character that distinguished them from Rocky Mountain bighorn sheep. Bighorn sheep from the Sierra Nevada were found to be distinguishable from those of the adjacent Great Basin region. Our morphometric results were concordant in geographic patterns with mtDNA data. We synonymize O. c. auduboni with O. c. canadensis. We also assign extant and extinct native populations of O. c. californiana from British Columbia and Washington to O. c. canadensis. Finally, we assign the extinct native populations of O. c. californiana from Oregon, southwestern Idaho, northern Nevada, and northeastern California to the Great Basin Desert form of O. c. nelsoni, recognizing that some transition to Rocky Mountain bighorn sheep probably occurred along that northern boundary. With these taxonomic revisions, the range of O. c. californiana includes only the central and southern Sierra Nevada.

Die Türkistangare (Tangara mexicana) - ihre Unterarten und Farbvarianten.

Gefiederter Freund 68 (2): 4-7.

Die farbenprächtigsten Vögel findet man unter den Schillertangaren, die in Lateinamerika verbreitet sind. Wurden sie von den 1970er bis in die 1990er Jahre auch von Privaten gehalten, sind sie heute in der Schweiz weitgehend aus der Liebhaberhand verschwunden. Der Verfasser hielt und züchtete früher Tangaren und spürt ihnen heute im Verbreitungsgebiet nach. Er beschäftigt sich in diesem Artikel mit den komplexen Farbvarianten un Unterarten der Türkistangare.

Taxonomic revision of the pampas cat Leopardus colocola complex (Carnivora: Felidae): an integrative approach.

Zoological Journal of the Linnean Society
DOI: 10.1093/zoolinnean/zlaa043/5848237

Abstract:

The pampas cat Leopardus colocola has been subject to conflicting classifications over the years. Currently, one polytypic species with seven subspecies is recognized, but integrative taxonomic study for this debated group has never been done. Here, we combine the broadest morphological coverage of the pampas cat to date with molecular data and ecological niche models to clarify its species composition and test the validity of recently proposed subspecies. The multiple lines of evidence derived from morphology, molecular, biogeography and climatic niche datasets converged on the recognition of five monotypic species: L. braccatus, L. colocola, L. garleppi (including thomasi, budini, steinbachi, crespoi and wolffsohni as synonyms), L. munoai and L. pajeros (including crucina as synonym). These five species are morphologically diagnosable based on skin and skull traits, have evolved in distinct climatic niche spaces and were recovered in molecular species delimitation. Contrary to previous taxonomic arrangements, we do not recognize subspecies in pampas cats. To objectively define the two most controversial species, we designate neotypes for L. colocola and L. pajeros. The diversification of pampas cats is associated with Middle Pleistocene glaciations, but additional genetic samples from the central Andean region are still needed to conclusively reconstruct its evolutionary history.

BECKMANN-DAHL, R. (2019)

The Sandy Zebra Shark: A New Color Morph of the Zebra Shark Stegostoma tigrinum, with a Redescription of the Species and a Revision of Its Nomenclature.

Copeia, 107(3):524-541 (2019). https://doi.org/10.1643/CG-18-115

Abstract:

The Zebra Shark, in recent years known as Stegostoma fasciatum (Hermann, 1783), is well known for its dramatic ontogenetic change of color pattern, from striped (“zebra”) juveniles to spotted (“leopard”) adults. Nevertheless, many aspects of the species' biology, ecology, and morphology are still unknown or inadequately described, and its nomenclature is contentious. This study introduces a hitherto undescribed color morph of the Zebra Shark and provides an updated diagnosis and redescription of the species. Firstly, we establish that the Zebra Shark remains a single species based on genetic data from mitochondrial COI and ND4 markers. Secondly, through morphological analyses, we conclude that there are two morphs of the species, the known, zebra striped morph and a new, sandy colored morph. Both morphs were studied morphometrically to expose any ontogenetic changes, such as a decrease in the relative length of the tail with increasing total length (TL). The external coloration pattern clearly differentiates the two morphs, and both morphs can be further divided into three stages based on color pattern and size: juveniles (255–562 mm TL), transitionals (562–1395 mm TL), and adults (>1300 mm TL). The transitional sandy morph is dorsally covered by a swirly pattern of thin, dark brown bands edged with freckle-like brown spots. The adults are a uniform sandy beige, partially covered with brown freckles. A mature male of the zebra morph displayed a yet unknown feature of the claspers: a small, triangular spike extruding from the dorsal terminal of the clasper glands. Finally, we reviewed the nomenclature of the species and suggest that the original name Stegostoma tigrinum Forster, 1781, should be used as the senior synonym for the species.

New observations of the ‘extinct’ Barbary sheep Ammotragus lervia ornata in Egypt.

Oryx 36 (3): 301-304.

Abstract:

The Barbary sheep or aoudad Ammotragus lervia is widely distributed in the mountains of the Sahara and North Africa. The 2000 IUCN Red List assessment of the Egyptian subspecies A. l. ornata categorized this taxon as Extinct in the Wild. We present new evidence, collected during 1997–2000, that this subspecies is extant in both the extreme south-east and south-west of Egypt, and reassess the status of captive aoudad in Egypt. We recommend that the category of A. l. ornata on the IUCN Red List be changed to Critically Endangered, that conservation of wild aoudad in Egypt be prioritized, and that the subspecific status of both the wild and be reassessed.

The hog-badger is not an edentate: systematics and evolution of the genus Arctonyx (Mammalia: Mustelidae)

Zoological Journal of the Linnean Society 154 (2): 353–385. https://doi.org/10.1111/j.1096-3642.2008.00416.x

Abstract:

Hog-badgers (mustelid carnivorans classified in the genus Arctonyx) are distributed throughout East and Southeast Asia, including much of China, the eastern Indian Subcontinent, Indochina and the large continental Asian island of Sumatra. Arctonyx is usually regarded as monotypic, comprising the single species A. collaris F. Cuvier, 1825, but taxonomic boundaries in the genus have never been revised on the basis of sizeable series from throughout this geographical range. Based on a review of most available specimens in world museums, we recognize three distinctive species within the genus, based on craniometric analyses, qualitative craniodental features, external comparisons, and geographical and ecological considerations. Arctonyx albogularis (Blyth, 1853) is a shaggy-coated, medium-sized badger widely distributed in temperate Asia, from Tibet and the Himalayan region to eastern and southern China. Arctonyx collaris F. Cuvier, 1825, is an extremely large, shorter-haired badger, distributed throughout Southeast Asia, from eastern India to Myanmar, Thailand, Vietnam, Cambodia and Laos. The world's largest extant badger, A. collaris co-occurs with A. albogularis in eastern India and probably in southern China, and fossil comparisons indicate that its geographical range may have extended into central China in the middle Pleistocene. The disjunctly distributed species Arctonyx hoevenii (Hubrecht, 1891), originally described within the order ‘Edentata’ by a remarkable misunderstanding, is the smallest and darkest member of the genus and is endemic to the Barisan mountain chain of Sumatra. Apart from A. hoevenii, no other Arctonyx occurs on the Sunda Shelf below peninsular Thailand. The natural history of each species of Arctonyx, so far as is known, is briefly reviewed.
