PROTECTING JAPANESE GIANT SALAMANDERS (ANDRIAS JAPONICUS) IN THE NAWA RIVER BASIN, JAPAN: POLICY RECOMMENDATIONS ADDRESSING WATER POLLUTION AND WATERWAY DISRUPTION

The Japanese giant salamander, Andrias japonicus, is an iconic but declining species of aquatic amphibian.A population within the Nawa River Basin of Tottori Prefecture persists but faces two significant threats.The first major threat is waterway obstructions, in the form of dams, weirs, and concrete embankments, which severely fragment and degrade

Ponerine ants are generalist predators feeding on a variety of small arthropods, annelids, and isopods; however, knowledge of their bacterial communities is rather limited.This study investigated the bacterial composition and diversity in the digestive tract (different gut sections and the infrabuccal pockets (IBPs)) of two ponerine ant species (Od

Massive machine type communication (mMTC) serves an irreplaceable role in the development process of the Internet of Things (IoT).Because of its characteristics of massive connection and sporadic transmission, compressed sensing (CS) has been applied in joint user activity and data detection in the uplink grant-free non-orthogonal multiple access (

This paper presents an experimental method for assessing the performances what is faux shagreen made of and the propulsion power of a UAV in several points based on telemetry.The points in which we make the estimations are chosen based on several criteria and the fallowing parameters are measured: airspeed, time-to-climb, altitude and the horizonta

This paper presents the results of an experimental research designed to investigate the dynamic mechanical properties and constitutive model of fiber reinforced concrete (FRC), including steel fiber reinforced concrete (SFRC) and polypropylene fiber reinforced concrete (PFRC) under fast loading.Experimental results are achieved by using the electro
