A stochastic simulation model for Asian elephant Elephas maximus populations and the inheritance of tusks
Autorzy:
Tiedemann, R.
Kurt, F.
Powiązania:
Acta Theriologica
Opis:
In the framework of available historical data on population size and human impact on the Asia elephant Elephas maximus Linnaeus, 1758, we developed a stochastic simulation model for elephant populations, which simulates individual elephants and includes their geno- and phenotype regarding the tusk character. The model omits density dependence of reproduction parameters and mortality rates. The model predicts female mortality and mean calving interval to be the paramount factors determining the long-term population trend.

Socio-ethogram of adult males versus biochemical-genetic variation in assessing phylogenetic relationships of the Carpinae
Autorzy:
Hartl, G. B.
Kurt, F.
Powiązania:
Acta Theriologica
Opis:
To investigate phylogenetic relationships among 9 genera of the Caprinae (Capra, Ammotragus, Hemitragus, Pseudois, Ovis, Rupicapra, Oreamnos, Nemorhaedus, Capricornis) behaviours involved in courtship and mating, aggression, threat, dominance, submission, and marking of adult males were subjected to phylogenetic analysis. Based on all 32 characters and 96 character states investigated, phylogenetic patterns generally were in good agreement with biochemical-genetic data available.

Breeding strategies and genetic variation in European roe deer Capreolus capreolus populations

Hartl, G. B.
Kurt, F.
Powiązania:
Acta Theriologica
Opis:
Based on previously published electrophoretic data on genetic variability in 31 roe deer Capreolus capreolus Linnaeus, 1758, the proportion of loci polymorphic (P), average heterozygosity (H), and the inbreeding coefficient (FIS) were examined for relationships with the social structure displayed in the various populations.

Tuskless bulls in Asian elephant Elephas maximus . History and population genetics of a man-made phenomenon
Autorzy:
Tiedemann, R.
Hartl, G. B.
Kurt, F.
Powiązania:
Acta Theriologica
Opis:
In Asian elephant Elephas maximus Linnaeus, 1758 tuskless bulls or maknas are generally rare. Only in Sri Lanka 93% of subadult and adult bulls have been reported to be maknas. Using historical records and computer simulations we demonstrate that simulation in man-made. The following mechanisms were identified to be associated with a loss of tuskers: (1) When using elephants, man has always preffered tuskers. (2) Selective hunting and capturing frequently led to a decrease of tuskers in wild-living populations. (3) The impact of selective unting and capturing was highest in isolated populations, such as Sri Lanka. (4) Selective removal of tuskers for protecting a maximum wild-living male population resulted in an increase of maknas.

Differences in spatial genetic population structure between African and Asian elephant (Loxodonta africana, Elephas maximus) as revealed by sequence analysis of the mitochondrial Cyt b gene
Autorzy:
Haberhauer, A.
Tiedemann, R.
Hartl, G. B.
Kurt, F.
Powiązania:
Acta Theriologica
Opis:
To assess spatial genetic population structure of both extant elephant species, we investigated sequence variation in 369bp of the mitochondrial Cyt b gene in 23 specimes of African elephant Loxodonta africana (Blumenbach, 1797) from three regions in the Southern part of Africa.

A pulsed supersonic gas jet target for precision spectroscopy at the HITRAP facility at GSI

Malarz, Adam
Winters, D. F. A.

Warczak, Andrzej
Opis:
A pulsed supersonic gas jet target for experiments at the HITRAP facility at the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt has been designed and built as a multi-purpose installation for key experiments on fundamental atomic physics in strong fields. This setup is currently installed at the Institut für Kernphysik of Goethe-University, Frankfurt am Main (IKF), in order to explore its operation prior to its installation at the HITRAP facility. Design and performance of the target are described. The measured target densities of 5.9×10^{12} atoms/cm3 for helium and 8.1×10^{12} atoms/cm³ for argon at the stagnation pressure of 30 bar match the required values. The target-beam diameter of 0.9 mm and the pulsed operation mode (jet built-up-time ≤15 ms) are well suited for the use at HITRAP.
