SCHULTE, U. (2007)

Beobachtungen zur Hybridisierung zwischen Ctenosaura similis (Gray, 1831) und Ctenosaura bakeri Stejneger 1901 auf Utila, Honduras. 

Elaphe N.F. 15: 55-59.

Zusammenfassung:

Die honduranische Karibikinsel Utila ist der einzige bekannte Ort der Welt, an dem drei Großleguanarten vorkommen. Währenddem Iguana iguana rhinolopha primär die Feuchtwälder bewohnt und Ctenosaura bakeri exklusiv die schattigen Mangrovensümpfe besiedelt, bevorzugt Ctenosaura similis semiaride bis aride Lebensdräume mit starker Sonneneinstrahlung. Trotz dieser ökologischen Trennung wurde bereits in der Vergangenheit von fertilen Hybriden zwischen C. similis und C. bakeri berichtet. Neben der Beschreibung eines möglichen Hybridgürtels mit beonbachteten potenziellen Bastarden, wird die ökologische Anpassungs- und Ausbreitungsfähigkeit von C. similis aufgezeigt.

Über Neuguinea-Buschkängurus der Gattungen Dorcopsis Schlegel & Müller, 1845 und Dorcopsulus Matschie, 1916.
(On New Guinean marsupials of the genera Dorcopsis Schlegel & Müller, 1845 and Dorcopsulus Matschie, 1916.)

Der Zoologische Garten 88(1): 51-75.

Zusammenfassung:

Es wurde versucht, die Geschichte der Haltung aller Dorcopsis- und Dorcopsulus-Arten in zoologischen Einrichtungen zu dokumentieren, unter Auslassung solcher Haltungen, in denen die Artbestimmung nicht nachvollziehbar war. Ebenso wie die Importe von 1964 und 1968, in Wirklichkeit D. luctuosa, aber eingeführt als D. macleayi, gehören die neuen Importe von 2013 und 2015, die nach Angaben der Importeure D. hageni sein sollten, nicht zu dieser Art, sondern meines Erachtens zu D. muelleri. Die Angaben in ZIMS wären zu korrigieren.

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￿

Volltext: https://hal-normandie-univ.archives-ouvertes.fr/hal-02139257/document

Abstract:

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.

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.

A revised nomenclature and classification for family-group taxa of parrots (Psittaciformes).

Zootaxa 3205: 26-40. DOI:10.11646/zootaxa.3205.1.2

Abstract:

The last 20 years have seen a resurgence in systematic studies of parrots (Aves: Psittaciformes). Principally but not solely molecular in nature, this body of work has addressed the circumscription of higher level groupings within the Psittaciformes and relationships among them. Stability has now emerged on many formerly contentious matters at these levels. Accordingly, we consider it appropriate to underpin further work on parrot biology with a freshly revised classification at the taxonomic ranks spanned by family-group nomenclature, i.e., between superfamily and tribe. In light of the body of recent work, we advocate a framework of three superfamilies among parrots (Strigopoidea, Cacatuoidea and Psittacoidea) within which Linnaean taxonomy can accommodate present phylogenetic understanding by employing groupings at the ranks of family, subfamily and tribe. Just as importantly, we have addressed numerous issues of nomenclature towards stabilising the family-group names of parrots. We erect two new subfamily names, Coracopseinae Joseph, Toon, Schirtzinger, Wright & Schodde, subfam. nov. and Psittacellinae Joseph, Toon, Schirtzinger, Wright & Schodde, subfam. nov. We stress that rankings we have applied reflect the state of understanding of parrot phylogeny and how it can be summarized in a Linnaean system; comparisons with rankings in other groups are likely not appropriate nor relevant.

Global phylogeography of the genus Capreolus (Artiodactyla: Cervidae), a Palaearctic meso-mammal.

Zoological Journal of the Linnean Society, 2013. 13 Seiten, 3 Abb., DOI: 10.1111/zoj.12091.

Abstract:

Areas of sympatry and hybridization of closely related species can be difficult to assess through morphological differences alone. Species which coexist and are similar morphologically may be distinguished only with molecular techniques. The roe deer (Capreolus spp.) is a meso-mammal having a Palaearctic distribution, with two closely related species: the European C. capreolus and the Siberian C. pygargus. We analysed mtDNA sequences from 245 individuals, sampled through all the entire range of the genus, to investigate the distribution of genetic lineages and outline phylogeographical patterns. We found that: (1) a C. pygargus lineage occurs in Poland and Lithuania, much farther west than the area which so far was believed its westernmost limit; (2) no haplotype of this C. pygargus lineage matches any found in East Europe and Asia – this should rule out human introductions and may indicate Pleistocene–Holocene migrations from the east; (3) no geographical structuring of C. pygargus lineages occurs, questioning the existence of putative subspecies; (4) several genetic lineages of C. capreolus can be recognized, consistent with the existence of two subspecies, respectively in central–southern Italy and southern Spain. Coalescence times suggest that intraspecific variation in C. capreolus and C. pygargus developed approximately 100–10 kya. The extant mitochondrial lineages pre-dated the Last Glacial Maximum. Capreolus pygargus must have moved westward to Central Europe, where at least one genetic lineage still survives, coexisting with C. capreolus.

Bemerkungen zu zwei Rehschädeln aus dem Elburs-Gebirge, Iran.

Bonn. zool. Beitr. 39 (2/3): 229—235.

Zusammenfassung:

Zwei Rehschädel aus dem Elburs-Gebirge, die 1986 als Jagdtrophäen vorgelegt wurden, ragen erheblich in der Größe aus den Kleinrehen dieses Gebietes heraus. Sie stimmen mit Rehgeweihen der kleinsten Unterart des Sibirischen Rehes {Capreolus pygargus caucasicus) des nordwestlichen Kaukasusgebietes überein; ebenso mit der Originalbeschreibung (Dinnik 1910) und einigen Abbildungen. Es wird das Auftauchen großer Rehe in Populationen kleinwüchsiger Rehe diskutiert.
