Human-driven land-use changes increasingly threaten biodiversity. In agricultural ecosystems, abandonment of former farmlands constitutes a major land-use shift. We examined the relationships between areas in which agriculture has been abandoned and the distribution records of threatened plant species across Japan. We selected 23 plant species that are(More)

We compared the environmental and biotic characteristics of farm ponds with and without the invasive fish, largemouth bass (Micropterus salmoides), and bluegill (Lepomis macrochirus), with varying degrees of aquatic vegetation cover in western Japan. Redundancy analysis (RDA) revealed that aquatic vegetation cover and pond area were significant(More)
Although several studies have demonstrated that disturbance contributes to species’ diversity, little emphasis has been placed on the identification of species’ coexistence mechanisms related to life history traits. In this study, we compared species’ richness and components of plant communities around river confluences to explore how disturbance promotes(More)
Interfaces between terrestrial and stream ecosystems often enhance species diversity and population abundance of ecological communities beyond levels that would be expected separately from both the ecosystems. Nevertheless, no study has examined how stream configuration within a watershed influences the population of terrestrial predators at the(More)
