The heavy chain of an antibody is crucial for mediating antigen binding. IGHV genes, which partially encode the heavy chain of antibodies, exhibit vast genetic diversity largely through polymorphism and copy number variation (CNV). These genetic variations impact population-level expression levels. In this study, we analyzed expressed antibody transcriptomes and matched germline IGHV genes from donors from KwaZulu-Natal, South...

Aim The extraordinary diversity of plants across the Cape Floristic Region is characterized by considerable species turnover among sites. Phytophagous insects show similarly high turnover, but their patterns are closely coupled to those of their hosts. If the mechanisms underlying high plant turnover are not unique to plants, similar patterns of turnover should also be seen in non‐herbivorous arthropod groups. We tested this h...

Aim We investigated turnover and richness in Antarctic springtails to understand large‐scale patterns in soil faunal diversity and how these are altered by biological invasions. Location Antarctica and the Southern Ocean Islands. Taxon Collembola (springtails). Methods We developed a database of all springtail species recorded from the Antarctic region. The relationship of species richness and turnover to high‐resolution envir...
