Data from: Short‐term insurance versus long‐term bet‐hedging strategies as adaptations to variable environments
Understanding how organisms adapt to environmental variation is a key challenge of biology. Central to this are bet-hedging strategies that maximize geometric mean fitness across generations, either by being conservative or diversifying phenotypes. Theoretical models have identified environmental variation across generations with multiplicative fitness effects as driving the evolution of bet-hedging. However, behavioral ecology has revealed adaptive responses to additive fitness effects of environmental variation within lifetimes, either through insurance or risk-sensitive strategies. Here we explore whether the effects of adaptive insurance interact with the evolution of bet-hedging by varying the position and skew of both arithmetic and geometric mean fitness functions. We find that insurance causes the optimal phenotype to shift from the peak to down the less steeply decreasing side of the fitness function, and that conservative bet-hedging produces an additional shift on top of this, which decreases as adaptive phenotypic variation from diversifying bet-hedging increases. When diversifying bet-hedging is not an option, environmental canalization to reduce phenotypic variation is almost always favored, except where the tails of the fitness function are steeply convex and produce a novel risk-sensitive increase in phenotypic variance akin to diversifying bet-hedging. Importantly, using skewed fitness functions, we provide the first model that explicitly addresses how conservative and diversifying bet-hedging strategies might coexist.
Validation of the best bet Urochloa (Brachiaria) grass cultivars for increasing feed availability and improve livestock productivity in selected sites in Kenya
<p>The trials were carried out at the Kenya Agricultural and Livestock Research Organization's Centre Mwea and Kamweti Agricultural Training Centre (ATC), both in Kirinyaga County.</p>

Figure 2 - Maintenance and production costs of bet-hedging. I expect that aphids which invest into bet-hedging produce offspring of lower quality, irrespective of environmental conditions (maintenance costs). In addition, I expect that the costs increase when the bet-hedging trait is expressed (production costs). To test these hypotheses, the data will be analysed separately for sexual and parthenogenetic parents (dashed line = critical day length).

Figure 1 - Phenotypic variance in sexual offspring production. When aphids are subjected to different day lengths, the induction of sexual offspring follows a logistic curve. Near the critical day length (were 50% of the offspring are sexual) there is a transient period in which the choice of offspring type is stochastic. I expect that clones from predictable (black, circles) and unpredictable (red, triangles) environments differ in slope of day length response and thus in the extent of the transient period. In total, 12 clones, each from a different environment, will be tested.

Figure 3 - Intended setup of the main experiment. The focal generation will be kept on individual plants for its full lifetime (middle column), starting two days before birth (left column). All offspring will be raised into adults (right column) to determine the reproductive mode of their parents.
