MORITZ, T. & BRITZ, R. (2019)

Revision of the extant Polypteridae (Actinopterygii: Cladistia).

Ichthyological Exploration of Freshwaters. July 2019: 1-96. DOI:10.23788/IEF-1094

Abstract:

The species-level taxonomy of all extant members of the family Polypteridae is revised. Two genera are recognised: Polypterus and the monotypic Erpetoichthys. Thirteen species of Polypterus are regarded as valid: P. bichir (type species), P. ansorgii, P. congicus, P. delhezi, P. endlicherii, P. mokelembembe, P. ornatipinnis, P. palmas, P. polli, P. retropinnis, P. senegalus, P. teugelsi and P. weeksii. Polypterus lapradei and P. bichir katangae are considered junior synonyms of P. bichir. Polypterus senegalus meridionalis is synonymized with P. senegalus, and P. buettikoferi and P. retropinnis lowei are regarded as junior synonyms of P. palmas. Lectotypes of P. ansorgii, P. congicus and P. delhezi are designated. Distribution maps for each species are compiled and a key for all species of Polypteridae is provided.

Ancient origin and evolution of the Indian wolf: Evidence from mitochondrial DNA typing of wolves from Trans-Himalayan region and Peninsular India.

Genome Biology 4(6). DOI:10.1186/gb-2003-4-6-p6

Abstract:

The two wolf types found in India are represented by two isolated populations and believed to be two sub-species of Canis lupus. One of these wolf, locally called Himalayan wolf (HW) or Tibetan wolf, is found only in the upper Trans-Himalayan region from Himachal Pradesh to Leh in Kasmir and is considered to be C. lupus chanco. The other relatively larger population is of Indian Gray wolf (GW) that is found in the peninsular India and considered to be C. lupus pallipes. Both these wolves are accorded endangered species status under the Indian Wildlife Protection Act. In 1998 for the first time in India, we initiated molecular characterization studies to understand their genetic structure and taxonomic status. Since then, we have analyzed the genetic variability in 18 of the total of 21 HW samples available in Zoological parks along with representative samples of GW, wild dogs and jackals. Our study of mitochondrial DNA diversity across three different taxonomically informative domains i.e., cytochrome-B gene, 16S rDNA and hypervariable d-loop control region revealed HW to be genetically distinct from the GW as well as from all other wolves of the world, including C. lupus chanco from China. Most importantly, d-loop haplotypic diversity revealed both HW and GW from India to be significantly diverse from other wolf populations globally and showed that these represent the most ancient lineages among them. Phylogenetic analysis revealed the Indian wolves as two independent lineages in a clade distinct and basal to the clade of all wolves from outside of India. Conservative estimate of evolutionary time-span suggests more than one million years of separation and independent evolution of HW and GW. We hypothesize that Indian wolves represent a post-jackal pre-wolf ancestral radiation that migrated to India about 1-2 mya and underwent independent evolution without contamination from other wolf like canids. The study thus, suggests that Indian subcontinent had been one major center of origin and diversification of the wolf and related canids. Further, the significant degree of genetic differentiation of HW from GW and of these two from other wolves, suggest the interesting possibility of them to be new wolf species/subspecies in evolution that may need to be described possibly as C. himalayaensis and C. indica (or as C. lupus himalyaensis and C. lupus indica), respectively. Thus for the first time, the study reveals new ancient wolf lineages in India and also highlights the need to revisit the origin, evolution and dispersion of wolf populations in Asia and elsewhere. Simultaneously, it increases the conservation importance of Indian wolves warranting urgent measures for their effective protection and management, especially of the small HW population that at present is not even recognized in the canid Red List.

MENDOZA, J. & FRANCKE, O. (1997)

Systematic revision of Brachypelma red-kneed tarantulas (Araneae:Theraphosidae), and the use of DNA barcodes to assist in the identification and conservation of CITES-listed species.

Invertebrate Systematics 31(2):157-179. DOI:10.1071/IS16023

Abstract:

Mexican red-kneed tarantulas of the genus Brachypelma are regarded as some of the most desirable invertebrate pets, and although bred in captivity, they continue to be smuggled out of the wild in large numbers. Species are often difficult to identify based solely on morphology, therefore prompt and accurate identification is required for adequate protection. Thus, we explored the applicability of using COI-based DNA barcoding as a complementary identification tool. Brachypelma smithi (F. O. Pickard-Cambridge, 1897) and Brachypelma hamorii Tesmongt, Cleton & Verdez, 1997 are redescribed, and their morphological differences defined. Brachypelma annitha is proposed as a new synonym of B. smithi. The current distribution of red-kneed tarantulas shows that the Balsas River basin may act as a geographical barrier. Morphological and molecular evidence are concordant and together provide robust hypotheses for delimiting Mexican red-kneed tarantula species. DNA barcoding of these tarantulas is further shown to be useful for species-level identification and for potentially preventing black market trade in these spiders. As a Convention on International Trade in Endangered Species (CITES) listing does not protect habitat, or control wildlife management or human interactions with organisms, it is important to support environmental conservation activities to provide an alternative income for local communities and to avoid damage to wildlife populations.

Generic Revision in the Holarctic Ground Squirrel Genus Spermophilus.

Journal of Mammalogy 90 (2), 14 April 2009, Pages 270–305, https://doi.org/10.1644/07-MAMM-A-309.1

Abstract:

The substantial body of research on Holarctic ground squirrels amassed over the past century documents considerable variability in morphological, cytogenetic, ecological, and behavioral attributes in the genus Spermophilus F. Cuvier, 1825. Recent molecular phylogenetic studies suggest that the traditionally recognized genera Marmota Blumenbach, 1779 (marmots), Cynomys Rafinesque, 1817 (prairie dogs), and Ammospermophilus Merriam, 1892 (antelope ground squirrels) render Spermophilus paraphyletic, potentially suggesting that multiple generic-level lineages should be credited within Spermophilus. Herein, we recognize 8 genera formerly subsumed in Spermophilus, each of which is morphologically diagnosable, craniometrically distinctive, and recovered as a monophyletic clade in phylogenetic analyses utilizing the mitochondrial gene cytochrome b. Generic-level names are available for each of these ground squirrel assemblages, most of which are exclusively or predominantly North American in distribution (Notocitellus A. H. Howell, 1938; Otospermophilus Brandt, 1844; Callospermophilus Merriam, 1897; Ictidomys J. A. Allen, 1877; Poliocitellus A. H. Howell, 1938; Xerospermophilus Merriam, 1892; and Urocitellus Obolenskij, 1927). Only Spermophilus sensu stricto is restricted to Eurasia. Generic subdivision of Spermophilus more aptly illuminates the taxonomic relationships, ecomorphological disparity, and biogeographic history of Holarctic ground squirrels.

Marmota caligata (Rodentia: Sciuridae).

Mammalian Species 43 (884):155-171.

Abstract:

Marmota caligata (Eschscholtz, 1829), a large ground squirrel commonly called the hoary marmot, is 1 of 15 species of extant marmots. It is distributed in western North America from Alaska and Canada south to Washington and Montana and is found at elevations ranging from sea level to 2,500 m . M . caligata prefers alpine and subalpine boulder piles and talus slopes surrounded by meadows. The species is listed as "Least Concern" by the International Union for Conservation of Nature and Natural Resources, although populations of Montague Island and Glacier Bay are of conservation concern by the State of Alaska.
