Concentrations of polybrominated diphenyl ethers (PBDE) in UK sparrowhawk (Accipiter nisus) livers. Data from the Predatory Bird Monitoring Scheme (PBMS)

J. Crosse, R. Shore, K. Jones & M. G. Pereira
Data on concentrations of PBDEs found in the livers of 59 sparrowhawks that had died in the UK between 1998 and 2009. Samples were selected from the Predatory Bird Monitoring Scheme (PBMS) Archive. Archived livers from birds that had died between 1998 and 2009 from central England, directly east and within 250 km of the Welsh border, were analysed. Data are presented as one table and two supporting files containing metadata. The Predatory Bird Monitoring...

Data from: Pest tradeoffs in technology: reduced damage by caterpillars in Bt cotton benefits aphids

Steffen Hagenbucher, Felix L. Wäckers, Felix E. Wettstein, Dawn M. Olson, John R. Ruberson, Jörg Romeis & F. L. Wackers
The rapid adoption of genetically engineered (GE) plants that express insecticidal Cry proteins derived from Bacillus thuringiensis (Bt) has raised concerns about their potential impact on non-target organisms. This includes the possibility that non-target herbivores develop into pests. Although studies have now reported increased populations of non-target herbivores in Bt cotton, the underlying mechanisms are not fully understood. We propose that lack of herbivore-induced secondary metabolites in Bt cotton represents a mechanism that benefits non-target...

Data from: Endemic infection reduces transmission potential of an epidemic parasite during co-infection

Joanna Randall, Joanne Cable, Irina A. Guschina, John L. Harwood & Joanne Lello
Endemic, low-virulence parasitic infections are common in nature. Such infections may deplete host resources, which in turn could affect the reproduction of other parasites during co-infection. We aimed to determine whether the reproduction, and therefore transmission potential, of an epidemic parasite was limited by energy costs imposed on the host by an endemic infection. Total lipids, triacylglycerols (TAG) and polar lipids were measured in cockroaches (Blattella germanica) that were fed ad libitum, starved or infected...

Data from: Dynamics of macronutrient self-medication and illness-induced anorexia in virally-infected insects

Sonia Povey, Kenneth Wilson, Sheena C. Cotter & Stephen J. Simpson
1. Some animals change their feeding behaviour when infected with parasites, seeking out substances that enhance their ability to overcome infection. This “self-medication” is typically considered to involve the consumption of toxins, minerals or secondary compounds. However, recent studies have shown that macronutrients can influence the immune response, and that pathogen-challenged individuals can self-medicate by choosing a diet rich in protein and low in carbohydrates. Infected individuals might also reduce food intake when infected (i.e....
