  • toward a spatial perspective of plant based Indirect Interaction webs scaling up trait mediated Indirect Interactions
    Perspectives in Plant Ecology Evolution and Systematics, 2015
    Co-Authors: Takayuki Ohgushi, Peter A Hamback
    Abstract:

    Phenotypic plasticity of plants following herbivory is ubiquitous in a wide range of terrestrial systems. Importantly, it can largely determine community properties of arthropods associated with induced plants. Effects of herbivore-induced plant phenotypes on species diversity, abundance, and community composition of higher trophic levels would depend on spatial variations in the altered phenotypes. To understand how arthropod communities are organized by plant phenotypic plasticity, we should focus on neighbor effects, as well as how these effects scale up to influence community structure and biodiversity within and between plant populations. Here, we encourage ecologists to meet the challenge of this novel issue by addressing the scaling up of trait-mediated Indirect effects of the prevalent herbivory via plant phenotypic plasticity in a spatial context. We first examine how herbivore-induced phenotypic plasticity in terrestrial plants affects arthropod communities. Specifically, we review how different types of induced plant traits alter species diversity, overall abundance, and community composition of associated arthropods. Second, we provide a conceptual framework addressing how the combinations of induced and constitutive (i.e., non-induced) traits in a plant population result in resource heterogeneity available to herbivores in a more explicit spatial context. In particular, we pay special attention to the contrasting responses of specialist and generalist herbivores to induced plant phenotypes. Last, we highlight how induced resource heterogeneity affects distribution and diversity of arthropods through movements onto and away from plant individuals in a plant patch.

  • Indirect Interaction webs on tall goldenrod: community consequences of herbivore-induced phenotypes and genetic variation of plants
    Journal of Plant Interactions, 2011
    Co-Authors: Takayuki Ohgushi, Shunsuke Utsumi, Yoshino Ando, Timothy P. Craig
    Abstract:

    Abstract Tall goldenrod, Solidago altissima, was introduced from North America 100 years ago, and it has become widely distributed all over Japan. We have been investigating plant-based Indirect Interaction webs on the tall goldenrod in Japan and the US. We found that arthropod communities on Japanese goldenrods are organized via plant- and ant-mediated Indirect effects caused by the dominant aphid, Uroleucon nigrotuberculatum, which came from the US in the early 1990s. The aphid also generated bottom-up cascading effects on temporally separated communities. Our results highlight the importance of herbivore-induced plant phenotypes in determining the structure of Indirect Interaction webs. We review our ongoing research that focuses on the effect of plant genotypic variation on the formation of Indirect Interaction webs. Our findings of the genotypic effects on aphid population dynamics and herbivore community composition provide a more complete understanding of the community consequences of plant genotyp...

  • herbivore induced Indirect Interaction webs on terrestrial plants the importance of non trophic Indirect and facilitative Interactions
    Entomologia Experimentalis Et Applicata, 2008
    Co-Authors: Takayuki Ohgushi
    Abstract:

    One of the most important issues in ecology is understanding the causal mechanisms that shape the structure of ecological communities through trophic Interactions. The focus on direct, trophic Interactions in much of the research to date means that the potential significance of non-trophic, Indirect, and facilitative Interactions has been largely ignored in traditional food webs. There is a growing appreciation of the community consequences of such non-trophic effects, and the need to start including them in food web research. This review highlights how non-trophic, Indirect, and facilitative Interactions play an important role in organizing the structure of plant-centered arthropod communities. I argue that herbivore-induced plant responses, insect ecosystem engineers, and mutualisms involving ant-honeydew-producing insects all generate Interaction linkages among insect herbivores, thereby producing complex Indirect Interaction webs on terrestrial plants. These Interactions are all very common and widespread on terrestrial plants, in fact they are almost ubiquitous, but these Interactions have rarely been included in traditional food webs. Finally, I will emphasize that because the important community consequences of these non-trophic and Indirect Interactions have been largely unexplored, it is critical that Indirect Interaction webs should be the focus of future research.

  • Linkages among trait-mediated Indirect effects: a new framework for the Indirect Interaction web
    Population Ecology, 2010
    Co-Authors: Shunsuke Utsumi, Yoshino Ando, Takeshi Miki
    Abstract:

    Plants have diverse ways of responding to damage by herbivores, such as changes in allelochemistry, physiology, morphology, growth, and phenology. These responses form the mechanistic basis for trait-mediated Indirect Interactions (TMIIs) between organisms on the plants. There is a growing appreciation that such TMIIs form complex networks (i.e., Indirect Interaction webs) in terrestrial plant-associated arthropod communities. Almost all previous studies have had the same framework: examining trait-mediated Indirect effects within a single interactive unit consisting of one initiator of herbivore, a host plant as a mediator, and one receiver [trait-mediated Indirect Interaction unit (TMIU)]. However, this framework is too simple to understand the dynamics of the Indirect Interaction web. Recent studies suggest that there is a wide variety of Interactions among TMIUs within a community, which may largely affect the outcomes of Indirect effects in each unit. Here, we review recent advance in studies of trait-mediated Indirect effects in plant-associated arthropod communities and explore the mechanisms of linkages among TMIUs. Then, we argue the importance of examining linkages among TMIUs as a new framework for future studies on the Indirect Interaction web. Finally, we propose the hypothesis that linkages among TMIUs contribute to the maintenance of biodiversity.

  • Indirect Interaction in environments for multi-agent systems
    Lecture Notes in Computer Science, 2006
    Co-Authors: David Keil, Dina Goldin
    Abstract:

    The E4MAS community is leading an effort to accept environments of multi-agent systems as a first-class entity, distinguishing Indirect Interaction via the environment from the environment's role in message transport. This paper defines classes of Interaction (sequential and multi-agent, direct and Indirect) and environments (physical and virtual, persistent and amnesic, dynamic and static). These notions provide an underpinning for proper acknowledgement of the roles of MAS environments and for powerful MAS design techniques that use Indirect Interaction. We explore the limitations of MAS models that are restricted to message passing and suggest research directions for constructing more powerful models.

    Co-Authors: David Keil, Dina Goldin
    Abstract:

    Open systems are part of a paradigm shift from algorithmic to interactive computation. Multiagent systems in nature that exhibit emergent behavior and stigmergy offer inspiration for research in open systems and enabling technologies for collaboration. This contribution distinguishes two types of Interaction, directly via messages, and Indirectly via persistent observable state changes. Models of collaboration are incomplete if they fail to explicitly represent Indirect Interaction; a richer set of system behaviors is possible when computational entities interact Indirectly, including via analog media, such as the real world, than when Interaction is exclusively direct. Indirect Interaction is therefore a precondition for certain emergent behaviors.

    Co-Authors: Dina Goldin, David Keil
    Abstract:

    Unlike direct Interaction based on message passing, Indirect Interaction takes place between agents as they make and observe persistent changes to their shared environment. The dining philosophers and foraging ants problems illustrate the characteristics that distinguish Indirect from direct Interaction, such as persistence, space and time decoupling, dynamic binding of recipient, and lack of intent. We point out that Indirect Interaction is an important phenomenon in many different fields within and outside computer science, including open systems, and merits explicit formal modeling.
