Project description:Using a combination of Whole Genome Bisulfite Sequencing (WGBS) and RNA Sequencning (RNA-seq) we explored the effect that the loss of maternal care has on newly eclosed female offspring in the subsocial carpenter bee Ceratina calcarata.

Project description:We use ZooMS to obtain secure species identifications of key specimens of early domesticated fauna from South Africa, dating to ca. 2000 BP. Because it can be difficult to distinguish between fragmentary remains of early domesticates (sheep) and similar-sized local wild bovids (grey duiker, grey rhebok, springbok) based on morphology alone, we explore the use of biomolecular methods to make these distinctions. As well as the traditional method of analysing bone fragments, we show the utility of minimally destructive sampling methods such as PVC eraser and polishing films for successful ZooMS identification. We also show that collagen extracted more than 25 years ago for the purpose of radiocarbon dating can yield successful ZooMS identification. Our study demonstrates the importance of developing appropriate regional frameworks of comparison for future research using ZooMS as a method of biomolecular species identification on archaeological faunal assemblages. We confirm that the specimen from the site of Spoegrivier dated to 2105±65 BP is indeed a sheep. This is the earliest directly dated evidence of domesticated animals in southern Africa.
Project description:In this study we addressed whether the transcriptome profile in the honey bee brain is similar for two major parasites of honey bee, Varroa destructor and Nosema ceranae. Honey bees parasitized by these two parasites show accelerated behavioral maturation and deficiences in orientation and learning/memory that we hoped to characterized at the transcriptomic level.
