Contrasting impacts of invasive engineers on freshwater ecosystems: an experiment and meta-analysis
Both carp and crayfish have profound effects on community composition and ecosystem processes through combined consequences of bioturbation, excretion, consumption and non-consumptive destruction, indicating that they have differential ecosystem impacts. Expand
Invasion Status and Potential Ecological Impacts of an Invasive Alien Bumblebee, Bombus terrestris L. (Hymenoptera: Apidae) Naturalized in Southern Hokkaido, Japan
The numbers of B. terrestris captured or observed have increased rapidly during the eight years since the evidence of its naturalization was found, and it clearly has the potential to compete with native bumblebees for floral resources and nest sites. Expand
Displacement of Japanese native bumblebees by the recently introduced Bombus terrestris (L.) (Hymenoptera: Apidae)
It is suggested that competition for nest sites rather than flower resources is the major ecological mechanism for displacement of native bees, which may cause local extinction of native bumblebees. Expand
Citizen science: a new approach to advance ecology, education, and conservation
Citizen science has a long history in the ecological sciences and has made substantial contributions to science, education, and society. Developments in information technology during the last fewExpand
Effects of common carp on nutrient dynamics and littoral community composition: roles of excretion and bioturbation
Carp can have dramatic direct and indirect impacts on nutrient dynamics and littoral community structure through excretion and bioturbation, indicating that ecosystem engineering by carp may trigger a shift from a clear water state dominated by submerged macrophytes to a turbid water statedominated by phytoplankton.

Patterns and consequences of stigma height variation in a natural population of a distylous plant, Primula sieboldii
Morph difference in reproductive success and the natural selection revealed for higher stigmas in the short-styled morph should be ascribed to the narrow corolla tube of the species that strictly restrict the path of the proboscis of the pollinators. Expand
Using monitoring data gathered by volunteers to predict the potential distribution of the invasive alien bumblebee Bombus terrestris
The use of ecological niche-modeling from data compiled in a participatory program of thousands of volunteer observers to quantitatively evaluate the spatial risk of invasion by the alien species Bombus terrestris indicated that the data compiled by participatory programs were useful for generating predictive models of the potential distribution of this invasive species.

Contributions of diffusional limitation, photoinhibition and photorespiration to midday depression of photosynthesis in Arisaema heterophyllum in natural high light
The increased Rubisco content in sun leaves, which has been recognized as raising photosynthetic assimilation capacity, also contributes to increase in the capacity for photorespiration. Expand
