Data from: Predator co-evolution and prey trait variability determine species coexistence

Thomas Scheuerl, Johannes Cairns, Lutz Becks & Teppo Hiltunen
Predation is one of the key ecological mechanisms allowing species coexistence and influencing biological diversity. However, ecological processes are subject to contemporary evolutionary change, and the degree to which predation affects diversity ultimately depends on the interplay between evolution and ecology. Furthermore, ecological interactions that influence species co-existence can be altered by reciprocal co-evolution especially in the case of antagonistic interactions such as predation or parasitism. Here we used an experimental evolution approach to test...

Data from: Behaviour out of control: experimental evolution of resistance to host manipulation

Nina Hafer-Hahmann
Many parasites alter their host’s phenotype in a manner that enhances their own fitness beyond the benefits they would gain from normal exploitation. Such host manipulation is rarely consistent with the host’s best interests resulting in suboptimal and often fatal behaviour from the host’s perspective. In this case, hosts should evolve resistance to host manipulation. The cestode Schistocephalus solidus manipulates the behaviour of its first intermediate copepod host to reduce its predation susceptibility and avoid...

Data from: Extortion strategies resist disciplining when higher competitiveness is rewarded with extra gain

Lutz Becks & Manfred Milinski
Cooperative strategies are predicted for repeated social interactions. The recently described Zero Determinant (ZD) strategies enforce the partner’s cooperation because the ‘generous’ ZD players help their cooperative partners while ‘extortionate’ ZD players exploit their partners’ cooperation. Partners may accede to extortion because it pays them to do so, but the partner can sabotage his own and his extortioner’s score by defecting to discipline the extortioner. Thus, extortion is predicted to turn into generous and disappear....

Data from: Experimental evolution of parasitic host manipulation

Nina Hafer-Hahmann
Host manipulation is a parasite-induced alteration of a host’s phenotype that increases parasite fitness. However, if genetically encoded in the parasite, it should be under selection in the parasite. Such host manipulation has often been assumed to be energetically costly, which should restrict its evolution. Evidence of such costs, however, remains elusive. The trophically-transmitted cestode Schistocephalus solidus manipulates the activity of its first intermediate copepod host to reduce its predation susceptibility before the parasite is...

Data from: Evolution of mating types in finite populations: the precarious advantage of being rare

Peter Czuppon & David Rogers
Sexually reproducing populations with self-incompatibility bear the cost of limiting potential mates to individuals of a different type. Rare mating types escape this cost since they are unlikely to encounter incompatible partners, leading to the deterministic prediction of continuous invasion by new mutants and an ever increasing number of types. However, rare types are also at an increased risk of being lost by random drift. Calculating the number of mating types that a population can...

Data from: Repeatability of adaptive radiation depends on spatial scale: regional versus global replicates of stickleback in lake versus stream habitats

Antoine Paccard, Dieta Hanson, Yoel E Stuart, Frank A Von Hippel, Martin Kalbe, Tom Klepaker, Skúli Skúlason, Bjarni K Kristjánsson, Daniel I Bolnick, Andrew P Hendry & Rowan D H Barrett
The repeatability of adaptive radiation is expected to be scale dependent, with determinism decreasing as greater spatial separation among “replicates” leads to their increased genetic and ecological independence. Threespine stickleback (Gasterosteus aculeatus) provide an opportunity to test whether this expectation holds for the early stages of adaptive radiation -their diversification in freshwater ecosystems has been replicated many times. To better understand the repeatability of that adaptive radiation, we examined the influence of geographic scale on...

Camera transects as a method to monitor high temporal and spatial ephemerality of flying nocturnal insects

Ireneusz Ruczyński, Zuzanna Hałat, Marcin Zegarek, Tomasz Borowik & Dina K. N. Dechmann
1. The current global decline of insects will have profound cascading effects as insects serve numerous roles in ecosystems. Effective but simple methods are needed to describe spatial and temporal distribution of flying insects in detail. This applies especially to important but short-lived phenomena such as insect swarms. 2. We developed, tested and implemented a non-invasive unbiased method with camera transects to measure spatio-temporal fluctuations in the abundance of nocturnal flying insects in different habitats....
