A glimpse into the foraging and movement behaviour of Nyctalus aviator; a complementary study by acoustic recording and GPS tracking
Autor: Yoshifumi Niga, Emyo Fujioka, Olga Heim, Akito Nomi, Dai Fukui, Shizuko Hiryu
Publikováno v: Royal Society Open Science, Vol 10, Iss 6 (2023)
Species of open-space bats that are relatively large, such as bats from the genus Nyctalus, are considered as high-risk species for collisions with wind turbines (WTs). However, important information on their behaviour and movement ecology, such as t

Coordinated Control of Acoustical Field of View and Flight in Three-Dimensional Space for Consecutive Capture by Echolocating Bats during Natural Foraging.
Autor: Miwa Sumiya, Emyo Fujioka, Kazuya Motoi, Masaru Kondo, Shizuko Hiryu
Publikováno v: PLoS ONE, Vol 12, Iss 1, p e0169995 (2017)
Echolocating bats prey upon small moving insects in the dark using sophisticated sonar techniques. The direction and directivity pattern of the ultrasound broadcast of these bats are important factors that affect their acoustical field of view, allow

Qualitative and quantitative analyses of the echolocation strategies of bats on the basis of mathematical modelling and laboratory experiments.
Autor: Ikkyu Aihara, Emyo Fujioka, Shizuko Hiryu
Publikováno v: PLoS ONE, Vol 8, Iss 7, p e68635 (2013)
Prey pursuit by an echolocating bat was studied theoretically and experimentally. First, a mathematical model was proposed to describe the flight dynamics of a bat and a single prey. In this model, the flight angle of the bat was affected by [Formula

Localization of Flying Bats from Multichannel Audio Signals by Estimating Location Map with Convolutional Neural Networks
Autor: Toru Tamaki, Emyo Fujioka, Bisser Raytchev, Yu Teshima, Kazuki Fujimori, Kazufumi Kaneda, Shizuko Hiryu, Yasufumi Yamada
Publikováno v: Journal of Robotics and Mechatronics. 33:515-525
We propose a method that uses ultrasound audio signals from a multichannel microphone array to estimate the positions of flying bats. The proposed model uses a deep convolutional neural network that takes multichannel signals as input and outputs the

Three-Dimensional Trajectory Construction and Observation of Group Behavior of Wild Bats During Cave Emergence
Autor: Emyo Fujioka, Shizuko Hiryu, Kazusa Ushio, Hitoshi Habe, Kyosuke Kohyama, Mika Fukushiro
Publikováno v: Journal of Robotics and Mechatronics. 33:556-563
Echolocating bats perceive the surrounding environment by processing echoes of their ultrasound emissions. Echolocation enables bats to avoid colliding with external objects in complete darkness. In this study, we sought to develop a method for measu

Discriminating predation attempt outcomes during natural foraging using the post-buzz pause in the Japanese large-footed bat, Myotis macrodactylus
Autor: Yuuka Mizuguchi, Emyo Fujioka, Olga Heim, Dai Fukui, Shizuko Hiryu
Publikováno v: Journal of Experimental Biology. 225
Bats emit a series of echolocation calls with an increasing repetition rate (the terminal buzz) when attempting to capture prey. This is often used as an acoustic indicator of prey-capture attempts. However, because it is directly linked to foraging

Foraging and commuting habitats of the greater horseshoe bat, revealed by high-resolution GPS-tracking
Autor: Dai Fukui, Shizuko Hiryu, Tomohiro Ujino, Koki Yoshimura, Ken Yoda, Emyo Fujioka
BackgroundEcholocating bats make a series of decisions to select their flight paths based on auditory information obtained by sonar as well as visual cues; accumulations of these flight routes are represented as daily movement patterns. However, ther
