This data paper reports bee occurrence data collected in citizen science program “Hanamaru-Maruhana national census” in Japan. We have confirmed all 16 bumble bee species inhabiting in the Japanese archipelago excluding the Kurile Islands, and have got 5503 occurrence data of these bumble bees. In addition, we have got 380 occurrence data of three carpenter bee species that are often mistaken for bumble bees by citizens.

In this study, we investigated that the relationship between species richness of wild-flowering plants at field margin before blooming or in blooming period of buckwheat and an abundance of flower-visiting insects on buckwheat in Japan. We found that the abundance of insects visiting buckwheat was positively related to the diversity of co-flowering plants at the field margin in autumn (September). The relationship would occur through the sharing of abundant insect species between co-flowering plants and buckwheat in autumn. The novel study suggests that the management of promoting wild-flowering plants' diversity would enhance pollination service on buckwheat yields.

Our coral reef model shows that ecological resilience could be more susceptible to the loss of habitat complexity than to that of ecosystem engineers. A general implication across ecosystems is that such influence of engineered structures on ecosystem dynamics would increase with their structural persistency and the strength of their interaction with biota.

Despite the lack of changes in δ¹⁵N of soil N ( the gray and pale gray bars indicate the ranges of δ¹⁵N of DON and NH₄⁺ (mean ± SD) across all 30 islands, respectively) as retrogression proceeded, the δ¹⁵N of most plant species increased. These results suggest that the N resources of plants change in response to retrogression: they have an increasing reliance on DON, a decreasing dependence on N transferred from the mycorrhizal fungi and reduced reliance on N from surface soil layers (e.g., the litter layer) as retrogression proceeds.

Global latitudinal patterns of the number of families, genera and species of pelagic, demersal, bony and cartilaginous fish were bimodal in all depth zones: high at the subtropics but with a dip at the equator.

I reviewed the current trends of conservation genetics using museum specimens. I present recommended genetic analysis methods and important points for the usage of museum. I also discuss perspectives on the future utility of conservation genetic studies using museum specimens.

We tested a hypothesis regarding species commonness using a database compiled by a citizen science program. The data used were more than 34,000 butterfly records posted by monitoring participants from 2009 to 2017. We concluded that the data collected by the monitoring program appear to represent the status of the butterfly community in Tokyo, a megacity subjected to rapid environmental changes.

Phenotypic polymorphism of leaf trichome density in the Bornean tropical alpine shrub Leptospermum recurvum involves a substantial level of gene flows between the populations of different phenotypic compositions and strong ongoing divergent selection.

In this article, we try to link the actual pattern of niche differentiation that can be observed in the fields to biogeographical histories. Based on the results, we discussed the evolutional and biogeographical history of the fine-scale topographical niche differentiation in the mountainous forests of the coastal areas of East Asia.

Our mathematical model shows that stage-specific responses of life history processes are an integral part of the mechanisms with which to predict the consequences of phenological species interactions at the community and ecosystem levels.

This manuscript used k-means clustering analysis to map global marine ecosystems with 20 environmental variables. The mapped ecosystems were compared with three previous global marine ecological partitions.

We review the current invasion status of the red imported fire ant, Solenopsis invicta in Asia-Pacific regions.
