FIG. 4 in Daily and seasonal variation in non-acoustic communicative behaviors of male greater short-nosed fruit bats (Cynopterus sphinx)
FIG. 4. Seasonal variation in duration and frequency of A — scent marking, B — wing flapping and C — open wing gesture behaviors. Mean ± SEM of frequency and duration varying between observed months (from January to December 2012). Mean ± SEM of number of attempts and duration was calculated from seven observation sessions for each month
FIG. 2 in Daily and seasonal variation in non-acoustic communicative behaviors of male greater short-nosed fruit bats (Cynopterus sphinx)
FIG. 2. Inter-individual variation in the mean frequency of A — scent marking, B — wing flapping and C — open wing gesture behavior between mating and non-mating seasons. Data shown as the mean of number of attempts (± SEM) made by focal bats between two mating and two non mating seasons. Each data point represents individual focal bat (Animal ID — A to F)
FIG. 3 in Daily and seasonal variation in non-acoustic communicative behaviors of male greater short-nosed fruit bats (Cynopterus sphinx)
FIG. 3. Daily variation in duration and frequency of A — scent marking, B — wing flapping and C — open wing gesture behaviors. Mean ± SEM of frequency and duration between observation sessions (one hour time interval). Mean ± SEM number of attempts and duration of each attempt were calculated for each observation session across 12 months (between January and December 2012) for all focal bats
FIG. 1 in Daily and seasonal variation in non-acoustic communicative behaviors of male greater short-nosed fruit bats (Cynopterus sphinx)
FIG. 1. Non-acoustic communicative displays of male C. sphinx. A — male bat scent marking the interior of palm leaves with its saliva during night time. Circled areas in the picture shows scent marked part of the leaf. B — Tagged male bat co-roosting with females (untagged) in the day roost and displaying open wing gesture during morning hours in the mating season

A tentative role of vibration-based communication in locust collective behavior
Locusts are renowned for their coordinated locomotion, or collective marching, in which juveniles swarm and walk in a synchronized fashion. While it is generally accepted that vision is the main form of communication enabling this behavior, it is suggested here that mechanical vibrations may also contribute to communication within the group. Using a laser Doppler vibrometer and accelerometer, the substrate vibration signals generated by locust walking, jumping, and coordinated marching were quantified in terms of frequency and amplitude. These mechanical signals were then artificially produced by a vibration generator and directly applied to the mechanical sensory receptors of experimental tethered locusts. A sensory threshold curve of the mechanical response of the locusts was established, in order to quantify and compare their ability to sense specific forms of locomotion, namely: individual walking, jumping, and coordinated group marching. While the vibrations generated by individuals walking in an unsynchronized fashion were below the sensory threshold of the locust, our findings indicate that locusts are capable of sensing the vibration signals generated by locust hopping or by the collective marching of conspecifics. It is suggested that locusts in a swarm may use substrate-borne mechanical vibrations for communication within the group, and that vibration-based communication may have a role in locust collective behavior and coordinated marching.
Directional speakers as a tool for animal vocal communication studies
<p class="MsoNormal"><span>Audio playback</span><span>s</span><span> are a common experimental tool in vocal communication research. However, low directionality of sound makes it hard to control the audience exposed to the stimuli. Parametric speakers offer a solution for transmitting directional audible signals by using ultrasonic carrier waves. The targeted transmission of vocal signals offers exciting opportunities for testing the diffusion of information in animal groups and mechanisms for resolving informational ambiguities. We have field tested the quality and directionality of a commercial parametric speaker, Soundlazer SL-01. Additionally, we assessed its usability for performing playback experiments by comparing behavioral responses of free ranging meerkats <em>(Suricata suricatta)</em> to calls transmitted from conventional and parametric speakers. Our results show that the tested parametric speaker is highly directional. However, the acoustic structure of meerkat calls was strongly affected and low frequencies were not reliably reproduced by the parametric speaker. The playback trials elicited weakened behavioral responses likely due to the partial distortion of the signal but also indicating the potential importance of social facilitation for initiating mobbing events in meerkats. We conclude that parametric speakers can be useful tool for directed transmission of animals calls but after a careful assessment of signal fidelity. </span></p>
