ABSTRACTSquamate reptiles exhibit high variation in their traits and geographical distribution and are therefore fascinating taxa for evolutionary and ecological research. However, high-quality genomic recourses are very limited for this group of species, which inhibits some research efforts. To address this gap, we assembled a high-quality genome of the common lizard Zootoca vivipara (Lacertidae) using a combination of high coverage Illumina (shotgun and mate-pair) and PacBio sequence data, with RNAseq data and genetic linkage maps. The 1.46 Gbp genome assembly has scaffold N50 of 11.52 Mbp with N50 contig size of 220.4 Kbp and only 2.96% gaps. A BUSCO analysis indicates that 97.7% of the single-copy Tetrapoda orthologs were recovered in the assembly. In total 19,829 gene models were annotated in the genome using a combination of three ab initio and homology-based methods. To improve the chromosome-level assembly, we generated a high-density linkage map from wild-caught families and developed a novel analytical pipeline to accommodate multiple paternity and unknown father genotypes. We successfully anchored and oriented almost 90% of the genome on 19 linkage groups. This annotated and oriented chromosome-level reference genome represents a valuable resource to facilitate evolutionary studies in squamate reptiles.

Common Milkweed Asclepias Syriaca

We investigated the extent of multiple paternity within and between fruits of the common milkweed, Asclepias syriaca, at one site. Using isozyme polymorphisms at four loci and the maximum likelihood methods of Williams and Evarts (1989), we found no statistical evidence for multiple paternity within fruits. When pairs of fruits obtained from individual ramets were analyzed in a similar manner, extensive multiple paternity was observed, indicating that fruits on the same ramet are sired by different paternal parents. This extensive multiple paternity between fruits provides considerable opportunity for maternal choice via selective fruit abortion. Key words: Asclepias, isozyme polymorphisms, multiple paternity, pollinia.

AbstractLittle is known about the mating system of the common wall lizard Podarcis muralis. Behavioural and observational data have demonstrated that females frequently mate with multiple males. However, the possible occurrence of multiple paternity has never been investigated. By using microsatellite paternity analysis in a wild population, we document this species indeed mate promiscuously and these matings resulted in multiple paternity in at least 87% of the clutches examined.

Astrometric Data

AbstractReduction techniques as applied to astrometric data material tend to split up traditionally into at least two different classes according to the observational technique used, namely transit circle observations and photographic observations. Although it is not realized fully in practice at present, the application of a blockadjustment technique for all kind of catalogue reductions is suggested. The term blockadjustment shall denote in this context the common adjustment of the principal unknowns which are the positions, proper motions and certain reduction parameters modelling the systematic properties of the observational process. Especially for old epoch catalogue data we frequently meet the situation that no independent detailed information on the telescope properties and other instrumental parameters, describing for example the measuring process, is available from special calibration observations or measurements; therefore the adjustment process should be highly self-calibrating, that means: all necessary information has to be extracted from the catalogue data themselves. Successful applications of this concept have been made already in the field of aerial photogrammetry.
