Data from: Time-lagged effects of weather on plant demography: drought and Astragalus scaphoides
Temperature and precipitation determine the conditions where plant species can occur. Despite their significance, to date, surprisingly few demographic field studies have considered the effects of abiotic drivers. This is problematic because anticipating the effect of global climate change on plant population viability requires understanding how weather variables affect population dynamics. One possible reason for omitting the effect of weather variables in demographic studies is the difficulty in detecting tight associations between vital rates and environmental drivers. In this paper, we applied Functional Linear Models (FLMs) to long-term demographic data of the perennial wildflower, Astragalus scaphoides, and explored sensitivity of the results to reduced amounts of data. We compared models of the effect of average temperature, total precipitation, or an integrated measure of drought intensity (Standardized Precipitation Evapotranspiration Index, SPEI), on plant vital rates. We found that transitions to flowering and recruitment in year t were highest if winter/spring of year t was wet (positive effect of SPEI). Counterintuitively, if the preceding spring of year t-1 was wet, flowering probabilities were decreased (negative effect of SPEI). Survival of vegetative plants from t-1 to t was also negatively affected by wet weather in the spring of year t-1, and for large plants, even wet weather in the spring of t-2 had a negative effect. We assessed the integrated effect of all vital rates on life history performance by fitting FLMs to the asymptotic growth rate, log(λt). Log(λt) was highest if dry conditions in year t-1 were followed by wet conditions in the year t. Overall, the positive effects of wet years exceeded their negative effects, suggesting that increasing frequency of drought conditions would reduce population viability of A. scaphoides. The drought signal weakened when reducing the number of monitoring years. Substituting space for time did not recover the weather signal, probably because the weather variables varied little between sites. We detected the SPEI signal when the analysis included data from two sites monitored over 20 years (2x20 observations), but not when analyzing data from four sites monitored over 10 years (4x10 observations).

Data from: Large-scale genetic panmixia in the blue shark (Prionace glauca): a single worldwide population, or a genetic lag-time effect of the "grey zone" of differentiation?
The blue shark Prionace glauca, among the most common and widely studied pelagic sharks, is a top predator, exhibiting the widest distribution range. However, little is known about its population structure and spatial dynamics. With an estimated removal of 10 to 20 million individuals per year by fisheries, the species is classified as "Near Threatened" by International Union for Conservation of Nature. We lack the knowledge to forecast the long-term consequences of such a huge removal on this top predator itself and on its trophic network. The genetic analysis of more than 200 samples collected at broad scale (from Mediterranean Sea, North Atlantic and Pacific Oceans) using mtDNA and nine microsatellite markers allowed to detect signatures of genetic bottlenecks but a nearly complete genetic homogeneity across the entire studied range. This apparent panmixia could be explained by a genetic lag-time effect illustrated by simulations of demographic changes that were not detectable through standard genetic analysis before a long transitional phase here introduced as the "population grey zone". The results presented here can thus encompass distinct explanatory scenarios spanning from a single demographic population to several independent populations. This limitation prevents the genetic-based delineation of stocks and thus the ability to anticipate the consequences of severe depletions at all scales. More information is required for the conservation of population(s) and managements of stocks, which may be provided by large scale sampling not only of individuals worldwide, but also of loci genome-wide.
Data from: Lagged effects of early-season herbivores on valley oak fecundity
The seasonal match between folivore and leaf phenology affects the annual success of arboreal folivore populations because many folivores exploit developing leaves, which are an ephemeral resource. One strategy for folivores to exploit early-season leaves is to anticipate their emergence. The consequence of this behavior for trees is that individuals that set leaves earlier may experience greater rates of folivore damage, with potential negative fitness consequences. To test this hypothesis, we surveyed the early-season phenology, insect folivore damage, and acorn crop of a population of valley oaks (Quercus lobata) over a 3-year period. We found that trees that set leaves earlier experienced greater rates of folivore damage than trees that set leaves later in the season. In addition, we observed a lagged effect of folivore damage on acorn production, whereby trees with greater leaf damage produced fewer acorns in the subsequent year. These results indicate potential negative fitness consequences of earlier leaf phenology. Our study suggests that folivore pressure may be one factor that affects the optimal timing of leaf set in oaks.

Lagged effects of herbivory impact host-choice but not nymphal survivorship in an ant-protected treehopper
<p>Theoretical studies have shown that in protection mutualism, modification of top-down control by protectors may be destabilizing. Central to this prediction are the assumptions that 1) protection mutualism increases the abundance of protected partners, 2) this increased abundance generates a lagged effect on partner resources, and 3) spatial dynamics can be ignored. Although a number of studies have confirmed that protection mutualism can increase the abundance of protected herbivores, the evidence for a negative effect of protected herbivores on plant quality is mixed, and we are unaware of any studies that have explored the effect of protected herbivores on plant quality across growing seasons. Here, we use the protection mutualism between ants and the treehopper <em>Publilia concava</em> to evaluate the assumption that treehopper herbivory has a lagged effect on plant quality. We also evaluated whether ant-protection exacerbated the negative effect of treehoppers on their host plants. We used a two-way factorial design that manipulated ant and treehopper presence on goldenrod host plants in one year, and assessed oviposition and survivorship on those same plants in the subsequent year. Treehopper herbivory was associated with a decrease in the probability of oviposition and female treehoppers laid significantly fewer egg masses on plants that had been fed on the previous year, regardless of ant-tending. In contrast, a prior history of herbivory had no impact on future treehopper performance as measured by nymph survival. Ant tending increased treehopper abundance and exacerbated the risk of plant mortality but otherwise did not significantly modify the negative effect of treehopper herbivory on plant quality or future treehopper performance. Although the increase in treehopper abundance associated with ant-tending and the lagged oviposition response of treehoppers is consistent with the core assumptions of a model showing that mutualism can be destabilizing, the avoidance of previously occupied plants for oviposition is not. These results highlight the importance of future modeling studies that explore spatiotemporal dynamics in protection mutualism, and long-term field studies that track the effect of mutualism across years.</p>
