Data from: Modeling effects of environmental change on wolf population dynamics, trait evolution, and life history

Tim Coulson, Daniel R. MacNulty, Daniel R. Stahler, Bridgett VonHoldt, Robert K. Wayne & Douglas W. Smith
Environmental change has been observed to generate simultaneous responses in population dynamics, life history, gene frequencies, and morphology in a number of species. But how common are such eco-evolutionary responses to environmental change likely to be? Are they inevitable, or do they require a specific type of change? Can we accurately predict eco-evolutionary responses? We address these questions using theory and data from the study of Yellowstone wolves. We show that environmental change is expected...

Data from: Different diversification rates between sexual and asexual organisms

Diego Fontaneto, Cuong Q. Tang, Ulrike Obertegger, Francesca Leasi & Timothy G. Barraclough
Patterns of diversity reflect the balance between speciation and extinction over time. Here we estimate net diversification rates for samples of sexual and asexual rotifers using phylogenetic reconstructions from sequence data of one mtDNA locus, cytochrome oxidase c subunit I. All four clades of bdelloid rotifers, obligate asexuals, had higher number of species per clade and significantly higher accumulation of diversification events towards the root of the trees than the four clades of their sexual...

Data from: Blocking the evolution of insecticide-resistant malaria vectors with a microsporidian

Jacob C. Koella, Adam Saddler & Thomas P. S. Karacs
Finding a way to block the evolution insecticide-resistance would be a major breakthrough for the control of malaria. We suggest that this may be possible by introducing a stress into mosquito populations that restores the sensitivity of genetically resistant mosquitoes and that decreases their longevity when they are not exposed to insecticide. We use a mathematical model to show that, despite the intense selection pressure imposed by insecticides, moderate levels of stress might tip the...

Data from: The microsporidian parasite Vavraia culicis as a potential late life-acting control agent of malaria

Lena M. Lorenz & Jacob C. Koella
Microsporidian parasites are being considered as alternatives to conventional insecticides for malaria control. They should reduce malaria transmission by shortening the lifespan of female mosquitoes and thus killing them before they transmit malaria. As the parasite replicates throughout the mosquito’s life, it should have little detrimental effects on young mosquitoes, thus putting less selection pressure on the hosts to evolve resistance. Here we examined these expectations for the microsporidian Vavraia culicis on Anopheles gambiae Giles...

Data from: Molecular detection of trophic links in a complex insect host-parasitoid food web

Jan Hrcek, Scott E Miller, Donald L J Quicke & M. Alex Smith
Previously, host-parasitoid links have been unveiled almost exclusively by time-intensive rearing, while molecular methods were used only in simple agricultural host-parasitoid systems in the form of species specific primers. Here we present a general method for molecular detection of these links applied to a complex caterpillar-parasitoid food web from tropical rainforest of Papua New Guinea. We DNA barcoded hosts, parasitoids and their tissue remnants and matched the sequences to our extensive library of local species....
