Data from: Genetic and life-history changes associated with fisheries-induced population collapse

Lilian Pukk, Anna Kuparinen, Leili Järv, Riho Gross & Anti Vasemägi
Over the recent years, growing number of studies suggests that intensive size-selective fishing can cause evolutionary changes in life-history traits in the harvested population, which can have drastic negative effects on populations, ecosystems and fisheries. However, most studies to date have overlooked the potential role of immigration of fish with different phenotypes as an alternative plausible mechanism behind observed phenotypic trends. Here, we investigated the evolutionary consequences of intensive fishing simultaneously at phenotypic and molecular...

Data from: Molecular identification of cryptic bumblebee species from degraded samples using PCR-RFLP approach

Salla-Riikka Vesterlund, Jouni Sorvari & Anti Vasemägi
The worldwide decline and local extinctions of bumblebees has raised a need for fast and accurate tools for species identification. Morphological characters are often not sufficient and molecular methods have been increasingly used for reliable identification of bumblebee species. Molecular methods often require high quality DNA which makes them less suitable for analysis of low quality or older samples. We developed an efficient PCR-RFLP identification method for four bumblebee species of the subgenus Bombus s....

Data from: Male mealworm beetles increase resting metabolic rate under terminal investment

Harmful parasite infestation can cause energetically costly behavioural and immunological responses, with the potential to reduce host fitness and survival. It has been hypothesized that the energetic costs of infection cause resting metabolic rate (RMR) to increase. Furthermore, under terminal investment theory, individuals exposed to pathogens should allocate resources to current reproduction when life expectancy is reduced, instead of concentrating resources on an immune defence. In this study, we activated the immune system of Tenebrio...
