Project description:The complete chloroplast genome of Androsace mariae was sequenced and assembled. It is a circular form genome of 151,958 bp in length, which was separated into four distinct regions, a large single-copy (LSC) of 83,292 bp, a small single-copy region (SSC) of 16,744 bp, two inverted repeats (IR) of 25,961 bp. After annotation, a total of 133 genes were predicted, of which, 87 were encoded proteins, 8 rRNA, and 37 tRNA. The evolutionary history, inferred using the neighbour-joining method, indicates that A. mariae was grouped within Primulaceae, and comprised a clade with other three species in Androsace, Androsace paxiana, Androsace laxa and Androsace bulleyana, with 100% bootstrap value.

Project description:Thermally influenced freshwater systems provide suitable conditions for non-native species of tropical and subtropical origin to survive and form proliferating populations beyond their native ranges. In Germany, non-native convict cichlids (Amatitlania nigrofasciata) and tilapia (Oreochromis sp.) have established populations in the Gillbach, a small stream that receives warm water discharge from a local power plant. Here, we report on the discovery of spotted tilapia (Pelmatolapia mariae) in the Gillbach, the first record of a reproducing population of this species in Europe. It has been hypothesized that Oreochromis sp. in the Gillbach are descendants of aquaculture escapees and our mtDNA analysis found both O. mossambicus and O. niloticus maternal lineages, which are commonly used for hybrids in aquaculture. Convict cichlids and spotted tilapia were most probably introduced into the Gillbach by aquarium hobbyists. Despite their high invasiveness worldwide, we argue that all three cichlid species are unlikely to spread and persist permanently beyond the thermally influenced range of the Gillbach river system. However, convict cichlids from the Gillbach are known to host both native and non-native fish parasites and thus, non-native cichlids may constitute threats to the native fish fauna. We therefore strongly recommend continuous monitoring of the Gillbach and similar systems.
