We found significant effects of local conspecific density on diversity in plant communities along four environmental gradients in the Japanese archipelago. The strength of local conspecific negative density dependence (CNDD) changes with altitude, and temperature and snow depth, which also affect species number. All these environmental gradients could be considered as surrogates of anthropogenic climate change. Regardless of the mechanisms involved, our results suggest that along the gradients, biotic interactions (represented by CNDD) were changing and have strong effects on species composition and diversity in forests. These effects are important under the current climate change scenario, especially when: (1) most of the endemic species in Japan are locally restricted in the mountain areas and the archipelago provides a regional diversity hotspot, (2) some forest types are at the edges of their climatic ranges and regulated by temperature, (3) we observed that species diversity was highly correlated with altitude, temperature and snow depth gradients.
