Abstract Species diversity, abundance and distribution relate to habitat preferences at multiple geographic ecological scales. In this study, we aimed understand the breeding ecology of five sympatric amphibians in Republic Korea – four anurans ( Bufo sachalinensis , Rana uenoi coreana huanrenensis ) one caudata Hynobius sp.) by characterising their spawning determine whether site preference wa...

Improving ecological connectivity (EC) within landscapes by establishing corridors and networks has been proposed to counteract the negative effects of habitat fragmentation climate change on biodiversity. To be functional, should kept free opportunistic invasive species that can disrupt EC between protected areas cause biodiversity loss. The present study focused perennial herbaceous whose occ...

The present article focuses on pressed biofuel preparation from invasive herbaceous plants, and the quality indicators properties were analyzed determined. Two plants chosen for this research: giant knotweed (Fallopia sachalinensis) Sosnowsky’s hogweed (Heracleum sosnowskyi). For a control, pine wood biomass was utilized. After harvesting drying, plant chopped milled later into cylindrical pell...

Reynoutria japonica (Japanese knotweed) is a problematic invasive plant found in many areas of Europe and North America. Notably, the UK, species can cause issues with mortgage acquisition. Control R. complicated by its ability to regenerate from small fragments material; however, there remains uncertainty about how much (in terms mass) rhizome required for successful regeneration. This study i...

Essential oils (EOs) from Abies sachalinensis (Sakhalin fir), a conifer species found in Sakhalin Island and Hokkaido Japan, effectively remove nitrogen dioxide possess antifungal activity. EOs also exert relaxing effect enhance air quality. Underwater shock waves generate instantaneous high pressure that ruptures cell walls, enhancing the performance of steam distillation oil extraction. In th...
