Day2 Abstract Following reports of an invasive snail causing crop damage in the expansive Mwea irrigation scheme in Kenya, samples of snails and associated egg masses were collected and sent to CABI laboratories in the UK for molecular identifcation. DNA barcoding analyses using the cytochrome oxidase subunit I gene gave preliminary identifcation of the snails as Pomacea canaliculata, widely considered to have the potential to be one of the most invasive inver- tebrates of waterways and irrigation systems worldwide and which is already causing issues throughout much of south-east Asia. To the best of our knowledge, this is the frst documented record of P. canaliculata in Kenya, and the frst confrmed record of an established population in continental Africa. This timely identifcation shows the beneft of molecular identifcation and the need for robust species identifcations: even a curated sequence database such as that provided by the Barcoding of Life Data system may require additional checks on the veracity of the underlying identifcations. We found that the egg mass tested gave an identical barcode sequence to the adult snails, allowing identifcations to be made more rapidly. Part of the nuclear elongation factor 1 alpha gene was sequenced to confrm that the snail was P.

However, it has invaded freshwater ecosystems and become a serious agricultural pest in paddy fields. Water temperature is an important factor determining behavior and successful establishment in new areas. We examined the behavioral responses of P. canaliculata with water temperature changes from 25 ◦C to 30 ◦C, 20 ◦C, and 15 ◦C by quantifying changes in nine behaviors. At the acclimated temperature (25 ◦C), the mobility of P. canaliculata was low during the day, but high at night. Clinging behavior increased as the water temperature decreased from 25 ◦C to 20 ◦C or 15 ◦C. Conversely, ventilation and food consumption increased when the water temperature increased from 25 ◦C to 30 ◦C. A self-organizing map (an unsupervised artificial neural network) was used to classify the behavioral patterns into seven clusters at different water temperatures. These results suggest that the activity levels or certain behaviors of P. canaliculata vary with the water temperature conditions.

Mickiewicza 30, 30-059 Cracow, Poland (e-mail: [email protected]); https://orcid.org/0000-0002-5403-6696 abstract: Long-term research on the malacofauna of the Beskid Mały, one of the ranges of the Western Beskidy Mts, was based on flood deposits of the streams cutting through the massif. Samples from limestone areas (called Andrychów Klippes) and those from the Żurawnica massif complemented the material. The total of ca. 400 samples yielded 78 species of terrestrial snails. The malacofauna was characterised in terms of its ecological and zoogeographical composition. The material provided the basis for determining the zones of occurrence and distribution of the component taxa within the Beskid Mały range. The ecological, zoogeographical and species diversity of the assemblages made it possible to distinguish four types of fauna, each connected with certain parts of the Beskid Mały range, which differ in their geological structure, relief and the degree of anthropogenic transformations.

Molecular studies on their relationships confirmed the distinctness of this family. Their monophyly, however, remained doubtful, since the Moitessieriidae did not form a distinct clade in the phylogenetic tree based on the most commonly applied mitochondrial cytochrome oxidase subunit I (COI), and the representative of the family Cochliopidae occupied a position among the moitessieriid clades. In the present paper two new nuclear loci, namely histone H3 gene and ribosomal internal transcribed spacer ITS2, have been applied to resolve the status of the Moitessieriidae.
