The marine dinoflagellate Alexandrium is associated with harmful algal blooms (HABs) worldwide, causing paralytic shellfish poisoning (PSP) in humans. We found that the marine bacterium Pseudoruegeria sp. M32A2M exhibits algicidal activity against Alexandrium catenella (Group I), inhibiting its motility and consequently inducing cell disruption after 24 h of co-culture. To understand the communication between the two organisms...

This study used the Hydrological Simulation Program—Fortran (HSPF) model to evaluate the river basin scale effects of nonpoint source (NPS) pollution loads caused by tillage and no‐tillage applications to upland crop areas. The study site was the Byulmi‐cheon river basin (1.21 km 2 ) of South Korea. Hourly rainfall, discharge and stream water quality data for 2 years (2012–2013) were collected at the river basin outlet. The HS...

This study describes the applicability of the Catchment hydrologic cycle Assessment Tool (CAT) for improving the water cycle in a river basin, and suggests appropriate water cycle improvement methods for adapting the impact of future climate change on river basin hydrology. For future assessment, the Gyeongan‐Cheon River Basin located in the north‐eastern part of South Korea was selected. To evaluate future water cycle improve...
