Gene flow is a crucial concept in the delineation of conservation units for natural populations of a species. Seagrasses are marine species targeted for conservation because their abundance has declined worldwide during the last century. However, knowledge of how to delineate seagrass conservation units based on their genetic structure is inadequate. In this study, the genomes of Zostera marina L. (eelgrass) populations in thr...

In Japan, agricultural drainage facilities such as pumping stations and drains are designed by calculating an approximately 10–30‐year return period based on observed precipitation in the past. However, damage to farmlands and agricultural facilities caused by heavy rainfall has become more severe and frequent in Japan. The Ministry of Agriculture, Forestry and Fisheries of Japan (MAFF) is urged to develop new design standards...

This study introduces a novel method for estimating floc conditions in sludge dewatering plants by employing image analysis and automatic control of polymer dosage. While previous research has focused on drinking water treatment plants, few reports address polymer dosage optimization using image analysis in sludge dewatering plants. The challenge lies in the high sludge dry solids hindering individual floc recognition due to o...

In Japan, mowing work on ridges of farms that cultivate rice is difficult for farmers, especially in hilly and mountainous areas. Moreover, geographical information on ridges in paddy fields has not been prepared; such information includes the slope angle, the ridge area, and the ridge rate of the total paddy field area. This issue causes a level of uncertainty in management analysis in terms of labor costs, including mowing c...

Mannosylerythritol lipid-B (MEL-B), which comprises ester-bonded hydrophilic ME and hydrophobic fatty acids, is a bio-surfactant with various unique properties, including antimicrobial activity against most gram-positive bacteria. The gram-positive Staphylococcus aureus is a causative pathogen of dairy cattle mastitis, which results in considerable economic loss in the dairy industry. Here, we demonstrate the efficacy of MEL-B...
