Effects of urban horticulture on insect pollinator community structure, central Arizona Phoenix: site locations
Insects that pollinate flowering plants are often considered "keystone species," animals that play extremely important roles in ecosystem functioning such that their absence would have more widespread and far-reaching effects than their abundance alone would indicate. For example, the absence of pollinating insects would translate to a severe reduction in plant reproduction, which would in turn affect not only the plants but also seed-eating animals, herbivorous animals, predators of the herbivores, and so on in a trophic cascade. Such a scenario would impact not only wildlife but also human populations because insects pollinate the majority of human food-plants. While the importance of these relationships is acknowledged, surprisingly, little is known about how insect pollinator communities are affected by environmental changes, such as global climate change or urban development. There has recently been a call for research on insect pollinator communities, citing a pressing need to obtain baseline information in the face of probable future environmental changes. The Sonoran Desert has one of the most diverse insect communities in the world (particularly for members of the Order Hymenoptera [bees, wasps, and ants], which perform the lion's share of pollination duties for both native and crop plants). This community may be threatened from the presence of the exotic honeybee and from habitat alteration in the form of urban development. We propose to conduct a pilot study to examine how the pollinator community differs under different forms of urban land use in the Phoenix metropolitan area. We have three research questions: (1) How does the ratio of native species to the exotic honeybee differ among natural desert, urban desert remnants, and residential areas that also have flowering plants? (2) How does insect pollinator community structure (richness and abundance) differ among natural desert, urban desert remnants, and residential areas? and (3) How does insect poll

Data from: Intraspecific variation in host plant traits mediates taxonomic and functional composition of local insect herbivore communities
<p class="abstract_para">Host plant phenotypic traits affect the structure of the associated consumer community and mediate species interactions. We compare herbivore assemblages from the canopy of the phenotypically variable tree <em class="fi">Metrosideros polymorpha</em> on Hawai'i Island. Multiple distinct varieties of <em class="fi">M. polymorpha</em> frequently co‐occur, with variation in morphological traits. Using this system, we identify host and insect traits that underlie patterns of herbivore abundance and quantify the strength of host‐insect trait interactions.</p> <p class="abstract_para">The dataset includes host plant phenotypic traits (specific leaf area, leaf water content, foliar nutrients, trichome presence), as well as collection information. The dataset also contains the herbivorous insect community associated with this host plant, their abundances and life history traits. R code for analyses in this article is also included.</p>
Data from: Effect of insect herbivory on plant community dynamics under contrasting water availability levels
1. Diversity of plant communities is impacted by multiple global change drivers but also by altered biotic interactions with antagonist and mutualist organisms that can potentially affect species coexistence. 2. With a two-year outdoor mesocosm experiment in realistic mesic grassland communities, we explored the role of insect herbivory in impacting plant community dynamics under contrasting levels of water availability simulating altered rainfall regimes. We selected a grasshopper species (Calliptamus italicus) feeding predominantly on forbs while avoiding grasses. 3. High water availability reduced species coexistence, boosting productivity while decreasing individual plant survival. At the community level, herbivores were not able to promote species coexistence but asymmetrically influenced grasses and forbs, reducing forb biomass under high water availability. 4. Herbivores shaped individual plant responses to both abiotic conditions and individual-neighbours' interactions. Herbivores influenced focal plant survival by altering the effect of neighbouring plants, mitigating the negative effect of high neighbour biomass at low water availability and exacerbating it at high level of water availability. 5. Synthesis: Altered rainfall has the capacity to change the relative strength of the plant-plant interactions and also to determine the effects of herbivores on grassland communities. The complexity of the interactions between plants and herbivores and the observed context-dependence indicate the need to incorporate multiple biotic and abiotic drivers to fully understand the mechanisms underlying plant dynamics and species coexistence in a changing world.
Host plant phenology, insect outbreaks and herbivore communities – the importance of timing
1. Climate change may alter the dynamics of outbreak species by changing the phenological synchrony between herbivores and their host plants. As host plant phenology has a genotypic component that may interact with climate, infestation levels among genotypes might change accordingly. When the outbreaking herbivore is active early in the season, its infestation levels may also leave a detectable imprint on herbivores colonizing the plant later in the season. 2. In this study, we first investigated how the spring phenology and genotype of Quercus robur influenced the density of the spring-active, outbreaking leaf miner Acrocercops brongniardellus. We then assessed how intraspecific density affected the performance of A. brongniardellus and how oak genotype and density of A. brongniardellus affected the insect herbivore community. 3. We found that Q. robur individuals of late spring phenology were more strongly infested by A. brongniardellus. Conspecific pupae on heavily infested oaks tended to be lighter, and fewer heterospecific insect herbivores colonized the oak later in the season. Beyond its effects through phenology, plant genotype left an imprint on herbivore species richness and on two insect herbivores. 4. Our results suggest a chain of knock-on effects from plant phenology, through the outbreaking species to the insect herbivore community. Given the finding of how phenological synchrony between the outbreak species and its host plant influences infestation levels, a shift in synchrony may then change outbreak dynamics and cause cascading effects on the insect community. 29-Oct-2019
