The inset shows the location of the four V. Factorial correspondence analysis performed for raccoons based on 16 microsatellite loci. While based on an over simplified approach, this latter analysis was performed in an attempt to account for genetic drift. Applying this to the national hunting bag gives an estimate of aboutraccoons in Germany. Reinhard Hendler betreut und in allen Phasen begleitet. The figure combines the results of Frantz et al. The genetic structure of the North American samples was weak and did not show any overlap with the Central European clusters.

Hunting bag data are routinely collected for game species, and these offer an additional monitoring strategy as they can be used as a general index of long term trends, population and distribution change and a proxy of abundance across time Cattadori et al.

However, if all sampled individuals from captive stocks were grouped together, genetic differentiation to the other genetic clusters was much lower, with minimum F ST -values of and for cluster HE and NA Table 3.

We used data from the first time step i. Are indirect measures of abundance a useful index of population density? On the other hand, some zoo populations are quite isolated, e. Because of this it was necessary to calibrate these colonization probabilities by finding the threshold that minimized the number of difference between omission false absence and commission false positive errors Jimenez-Valverde and Loboassessed by running the model starting at the distribution to predict the distribution.

Rapid genetic deterioration in captive populations: Flaschenhalseffekte in Anpassung an die neue Situation erfolgen Geiter et al. MEGA6, molecular evolutionary genetics analysis version 6. In order to facilitate geographical representation, the average q values for each administrative district Landkreis were calculated and mapped using ArcGIS In contrast to KA, the LU cluster had private alleles. A striking pattern from raccoon hunting bag data is that after over 60 years with a relatively stable population the density of raccoons increased dramatically in the s, and is still increasing even around the original introduction sites Figure 1.

After deciding on the most probable number of subpopulations based on the log-likelihood values and their convergence associated with each K, as well as on the K method by Evanno et al.

Invasive species, environmental change and niedereachsen, and health. No special permit was required to take samples from road-killed individuals. American Journal of Botany niiedersachsen, Lutz W Rates of range expansion can increase as spatial sorting leads to expanding range margins being dominated by strong dispersers Shine et al. Biology Letters 4 4Lutz W When removing all low-frequency alleles, we obtained estimates of 36 and 28 founders for BB and HE, respectively, while the corresponding estimates were 76 and 71 founders after removing non-private low-frequency alleles only.

Threshold criteria for conversion of probability of species presence to either or presence absence.

Molecular Ecology Resources 8. Journal of heredity niedersachseb. Network analysis short introduction 2. How reliable are harvesting data for analyses of spatio-temporal population dynamics?

How well do we understand the impacts of alien species on ecosystem services? Ex situ conservation genetics, a review of molecular studies on the genetic consequences of captive breeding programmes for endangered animal species. This indicates that it is not always appropriate to assume constant parameters throughout the process of range expansion, highlighting the importance of future work investigating the interactions between dispersal and habitat suitability in order to refine future modelling efforts.

Pairs of loci were tested for linkage disequilibrium using an exact test based on a Markov chain method as implemented in Genepop We visualized the genetic differentiation among the samples with a Factorial Correspondence Analysis FCA in Genetix Belkhir et al.

Modelling potential distribution of invasive species in different stages of invasion. The stochastic simulation models consistently predicted a greater area to be dispersed to than the deterministic model.

As raccoons are omnivorous generalists that can live in forested areas as well as in urban habitats Hohmann and Bartussekgenetic diversity might not be a short-term pre-requisite for raccoons to become successful invaders.

We introduce the general mode of action and instruments, that is, lists, risk assessments as well as measures, and further elaborate on ways to create a more efficient legislation Legal scope The proposed regulation and all measures it entails will only take effect for species listed on the List of IAS of Union concern see later section List of IAS of Union concern. AP Deutsch Sommerpaket The AP German exam is designed to test your language proficiency your ability to use the German language to speak, listen, read and write.

When resampling all alleles in the data sets analysis 1the inclusion of all individuals probably led to an overestimation of the number of the original founders of the two largest clusters BB and HE 97 or more.

Overview of EU legislative procedure: However, we recommend further improvements to achieve effective conservation management. Modell zur Untergliederung von Invasionsprozessen.

The inset shows the location of the four European countries sampled in this study: Cold spring harbor symposium on quantitative biology.

Single reports Stubbe and recent genetic studies already suggested that the invasion history of German raccoons might be more complex than often assumed. The sign is you personal number to be used in all exercises. So far, the results for Germany of this study are in line with the findings of our previous study Fischer et al.
