title: Data from: Predicting forest management effects on oak–rodent mutualisms

description: Wood mice Apodemus sylvaticus are the main dispersers of acorns in highly
 managed Mediterranean holm-oak woodlands. Mice mobilize and cache acorns
 to store them for winter consumption. They carry acorns away from
 potential competitors, face predation risks during mobilization, and cache
 acorns in areas where pilfering risks are low. However, mice can act
 either as net predators or as moderately efficient dispersers, depending
 on the way landscape management affects intraspecific competition for
 acorns and shelter availability. To assess the influence of landscape
 structure and mouse behavior on acorn dispersal, we developed an
 agent-based model (ABM) that translates forest management into changes in
 key environmental factors driving mouse foraging decisions. The model was
 able to predict accurately acorn dispersal patterns in a wide range of
 forest management practices based on information on forest habitat
 availability, stem density and shrub cover. Sensitivity analysis revealed
 that caching rates emerged from the interplay between intraspecific
 competition for seeds and predation risk accepted during mobilization. It
 also showed that intraspecific competition for acorns decreased with
 increasing habitat loss (due to positive edge effects on acorn production)
 while landscape resistance to mouse movements increased. As a result, the
 net benefits of caching declined and acorn predation became the dominant
 strategy. Finally, we assessed the effects of shrub encroachment as a
 management practice to enhance dispersal services in savanna-like
 landscapes (dehesas). The model predicted non-linear responses with a 65%
 threshold of shrub cover needed to achieve relatively high levels of acorn
 dispersal. This value may not be compatible with the traditional
 exploitation of dehesas (livestock rearing). Our study shows that
 integrated approaches that combine environmental change driven by
 management with behavioral responses of dispersers improve our
 understanding of the causes of recruitment bottlenecks, and are useful
 tools for evaluating conservation strategies aimed at enhancing dispersal
 services.

title: Data from: Predator-prey trophic relationships in response to organic management practices

description: A broad range of environmental conditions likely regulate predator-prey
 population dynamics and impact the structure of these communities. Central
 to understanding the interplay between predator and prey populations and
 their importance is characterizing the corresponding trophic interactions.
 Here we use a well-documented molecular approach to examine the structure
 of the community of natural enemies preying upon the squash bug, Anasa
 tristis, a herbivorous cucurbit pest that severely hinders organic squash
 and pumpkin production in the United States. Primer pairs were designed to
 examine the effects of organic management practices on the strength of
 these trophic connections and link this metric to measures of the
 arthropod predator complex density and diversity within an experimental
 open-field context. Replicated plots of butternut squash were randomly
 assigned to three treatments and were sampled throughout a growing season.
 Row-covers treatments had significant negative effects on squash bug and
 predator communities. In total, 640 predators were tested for squash bug
 molecular gut-content, of which 11% were found to have preyed on squash
 bugs, but predation varied over the season between predator groups
 (coccinellids, geocorids, nabids, web-building spiders and hunting
 spiders). Through the linking of molecular gut-content analysis to changes
 in diversity and abundance, these data delineate the complexity of
 interaction pathways on a pest that limits the profitability of organic
 squash production.

title: Data from: Does local adaptation to resources explain genetic differentiation among Daphnia populations?

description: Substantial genetic differentiation is frequently observed among
 populations of cyclically parthenogenetic zooplankton despite their high
 dispersal capabilities and potential for gene flow. Local adaptation has
 been invoked to explain population genetic differentiation despite high
 dispersal, but several neutral models that account for basic life history
 features also predict high genetic differentiation. Here, we study genetic
 differentiation among four populations of Daphnia pulex in east central
 Illinois. As with other studies of Daphnia, we demonstrate substantial
 population genetic differentiation despite close geographic proximity
 (&lt; 50 km; mean θ = 0.22). However, we explicitly tested, and failed
 to find evidence for, the hypothesis that local adaptation to food
 resources in these populations. Recognizing that local adaptation can
 occur in traits unrelated to resources, we estimated contemporary
 migration rates (m) and tested for admixture to evaluate the hypothesis
 that observed genetic differentiation is consistent with local adaptation
 to other untested ecological factors. Using Bayesian assignment methods,
 we detected migrants in three of the four study populations including
 substantial evidence for successful reproduction by immigrants in one
 pond, allowing us to reject the hypothesis that local adaptation limits
 gene flow for at least this population. Thus, we suggest that local
 adaptation does not explain genetic differentiation among these Daphnia
 populations, and that other factors related to extinction / colonization
 dynamics, a long approach to equilibrium FST, or substantial genetic drift
 due to a low number of individuals hatching from the egg bank each season
 may explain genetic differentiation.
