The idea that noncrop habitat enhances pest control and represents a win–win opportunity to conserve biodiversity and bolster yields has emerged as an agroecological paradigm. However, while noncrop habitat in landscapes surrounding farms sometimes benefits pest predators, natural enemy responses remain heterogeneous across studies and effects on pests are inconclusive. The observed heterogeneity in species responses to noncrop habitat may be biological in origin or could result from variation in how habitat and biocontrol are...

Data from: Exploring the causes of small effective population sizes in cyst nematodes using artificial Globodera pallida populations

Josselin Montarry, Sylvie Bardou-Valette, Romain Mabon, Pierre-Loup Jan, Sylvain Fournet, Eric Grenier & Eric J. Petit
The effective size of a population is the size of an ideal population which would undergo genetic drift at the same rate as the real population. The balance between selection and genetic drift depends on the effective population size (Ne), rather than the real numbers of individuals in the population (N). The objectives of the present study were to estimate Ne in the potato cyst nematode Globodera pallida and to explore the causes of a...

Data from: Intraspecific variation in litter palatability to macroarthropods in response to grazing and soil fertility

1. Clarifying the functional consequences of intraspecific trait variability in response to interacting trophic levels would provide a significant improvement in our understanding of aboveground-belowground linkages. In particular, the effects of grazing on plant traits may translate into altered litter quality, with potentially important consequences for litter-feeding decomposers. Plant and litter variability in response to grazing is expected to depend on soil fertility levels, with tolerance and defensive strategies more commonly expressed on fertile and...

Data from: Hosts do not simply outsource pathogen resistance to protective symbionts

Jan Hrcek, Benjamin J. Parker, Ailsa H.C. McLean, Jean-Christophe Simon, Ciara M. Mann & H. Charles J. Godfray
Microbial symbionts commonly protect their hosts from natural enemies, but it is unclear how protective symbionts influence the evolution of host immunity to pathogens. One possibility is that ‘extrinsic’ protection provided by symbionts allows hosts to reduce investment in ‘intrinsic’ immunological resistance mechanisms. We tested this idea using pea aphids (Acyrthosiphon pisum) and their facultative bacterial symbionts that increase host resistance to the fungal pathogen Pandora neoaphidis. The pea aphid taxon is composed of multiple...
