The horn shape and its sex dimorphism are compared in museum specimens of all geographical populations of the dama gazelle (Nanger dama). Departing from a putatively ancestral morphology prevailing in the west(-central) Sahel zone, a forked cladogenesis is inferred producing the eastern horn type of the red-necked gazelles (N. d. ruficollis) in Sud...
Twenty-five original prehistoric rock images from the Sahara in Libya, Niger, Mauretania and Algeria are presented which evidently or likely represent dama gazelles (Mammalia, Bovidae: Nanger dama (Pallas, 1766)). A literature revision of gazelles in North African rock art serves to interpret these new examples. Recurrent stylistic devices of engra...
The history of the discovery and the exploration of the hemione populations (Equus hemionus PALLAS) from Central Asia (Mongolia, northwest China, northeast Tibet, Kazakhstan, and Russian Siberia) from the 13th century to approximately 1950 are compiled with the aim to provide materials for a taxonomic and population genetic revision of the dziggeta...
Studbook records (1956–1992) of n = 1021 birth dates of hemione foals characterize the reproductive seasonality of E. h. kulan from Turkmenistan and E. h. onager from Iran in 33 European zoos, and in the equid sanctuaries at Askania Nova (Ukraine) and Canyon Colorado (New Mexico, U.S.A.). Husbandry practice introduces considerable artificial varian...
Cameroon is reported as a historical range country of the dama gazelle (Bovidae: Nanger dama), which has been overlooked by recent authors. Three historical literature records of 1852, 1854 and probably 1903-1904 reported dama gazelles at sites which later became incorporated into the historical German colony Deutsch-Kamerun, and the two more recen...
The hazel grouse populations in north-eastern France and adjacent regions are revised taxonomically on the basis of differentiated characters in morphometrics and plumage colouration of the two subspecies T. b. rhenana (n = 127) and T. b. styriaca (n = 102). In France, T. b. styriaca occurs in (parts of?) the Alps and T. b. rhenana in the Vosges mo...

Senn et al. (2014) and RZSS and IUCN Antelope SG (2014) claimed that the conservation of the dama gazelle would probably profit from lumping the different putative subspecies, and from combining the two traditional studbook projects by interbreeding them in zoological gardens. In this Opinion article we argue against this proposal considering the s...

Enzymes, representing 23 genetic loci, were studied in n = 320 European river barbels (Barbus barbus L. 1758) from the contact zone of the Rhine and the upper Danube. Barbel revealed the highest heterozygosity estimate (H(e) = 0.137) of 10 sympatric freshwater fishes (range H(e) = 0.017-0.106). The geographical genetic subdivision in barbel (G(ST)...
Allozyme analysis of 24 loci in 154 red kites (Milvus milvus) and 36 black kites (Milvus migrans) from die Hakel forest (Sachsen-Anhalt, Germany) revealed a Nei's interspecies genetic distance of D = 0.009. Of the observed genetic variance of four polymorphic enzymes, 15.4% referred to the differentiation between the kite species, but 84.6% were co...
Twenty-one allozyme loci, including fifteen polymorphisms, were studied in n = 317 minnows, Phoxinus phoxinus (LINNAEUS 1758), from 14 sites in the southern Rhine, Neckar, Danube, and the upper Elbe catchments. The heterozygosity estimate of He = 0.094 was subdivided into HeDON = 0.098 in the Danube, and HeRHE = 0.088 in the Rhine system. Despite m...
Abstract – Allozyme genetics (34 loci) is studied in up to 1010 European trout (Salmo trutta) from the Rhine, Meuse, Weser, Elbe and Danube river systems in Central Europe. Population samples from single collection sites, chiefly small streams (GCG = 0.2126), rather than the divergence of the trout from Atlantic and Danubian drainages (GSG = 0.0711...
Based on allozyme genetics, European sculpins or bullheads (Cottus gobio Linnaeus, 1758) from the Brenta River system (Adriatic basin, north east Italy) cluster with population sam- ples collected in the middle Danube catchment (Sava, Slovenia) and the Danubian headwaters, and with sculpins from the Lake Constance, but are more deeply differentiate...
Twenty-nine allozyme loci analyzed in 295 common gudgeons (Gobio gobio) from the Rhine, the upper Danube and the Elbe river systems revealed variability measures of P = 0.590, H(e) = 0.066, and G(ST) = 0.1415. Gene flow was estimated at N(e)m = 1.88 over 223 river km in the Danube basin, and at N(e)m = 1.96 over 300 river km in the Rhine system. Is...
Nine out of 57 bovine and caprine microsatellites investigated have proved polymorphic in roe deer populations from Central Europe. The polymorphism of four to nine microsatellites (with two to 16 alleles each) has been screened in 492 roe deer from 27 sample locations in Germany, the Netherlands and France, and 10 allozyme loci have been investiga...
The analysis of 25 allozyme loci in up to 469 Common Buzzards (B. b. buteo) from five locations in Germany revealed allelic polymorphism at twelve loci, but a prevalence of rare alleles resulted in a very low heterozygosity of H0=0.0057. This rather low level of genetic variation characterizes a most abundant raptor species with highly polymorphic...

Extensive review of the taxonomy and classification of Asiartic wild asses, including original research findings.
Enzyme polymorphism at 42 loci was compared before and after a major epidemy of swine fever in wild boars from northern Vosges (France). No change was observed in the 38 monomorphic loci, but allele frequencies at the phosphoglucomutase locus PGM-2* changed significantly. Possible causes for this observation are discussed, and it appears that PGM-2...
Morphometrical and biochemical-genetic comparisons were performed between wild (Mustela vison energumenos Bangs, 1896) and ranch mink (Dark Standard strain) to investigate intraspecific differences and to characterize effects of the domestication in this species. All animals were kept under similar conditions in larger open air enclosures prior to...
Allozyme variability was studied in 581 Porcellio scaber from 20 population samples in Germany, France, and Poland that were spaced at geographic distances ranging from a few metres to 1200 km.
