“…The great majority of vibrational signals are unknown, so it can be challenging for an inexperienced listener to distinguish signals from incidental vibrations caused by locomotion or feeding (Šturm et al, 2019). Computational methods for automatic classification and identification of vibrational signals have not yet been tested on field recordings (Korinšek et al, 2019;Šturm et al, 2019. Nevertheless, even taking into account specific challenges encountered in vibroscape recordings, automatic identification of signals should be possible using recent AI techniques such as convolutional neural networks applied to spectrogram images (Stowell et al, 2019).…”

“…First of all, the number of sources is relatively high, implying an additional level of complexity due to rich communities. Second, due to the complex pattern of vibration propagation through solids under field conditions, the degradation of signals is unpredictable with particularly important frequency and temporal changes (Michelsen et al, 1982;Casas et al, 2007;Polajnar et al, 2012;Mortimer, 2017;Brandt et al, 2018;Šturm et al, 2019). Third, ecotremology cannot refer to a public sample libraries as they exist for bird, amphibian or mammal sounds.…”

Our awareness of air-borne sounds in natural and urban habitats has led to the recent recognition of soundscape ecology and ecoacoustics as interdisciplinary fields of research that can help us better understand ecological processes and ecosystem dynamics. Because the vibroscape (i.e., the substrate-borne vibrations occurring in a given environment) is hidden to the human senses, we have largely overlooked its ecological significance. Substrate vibrations provide information crucial to the reproduction and survival of most animals, especially arthropods, which are essential to ecosystem functioning. Thus, vibroscape is an important component of the environment perceived by the majority of animals. Nowadays, when the environment is rapidly changing due to human activities, climate change, and invasive species, this hidden vibratory world is also likely to change without our notice, with potentially crucial effects on arthropod communities. Here, we introduce ecotremology, a discipline that mainly aims at studying substrate-borne vibrations for unraveling ecological processes and biological conservation. As biotremology follows the main research concepts of bioacoustics, ecotremology is consistent with the paradigms of ecoacoustics. We argue that information extracted from substrate vibrations present in the environment can be used to comprehensively assess and reliably predict ecosystem changes. We identify key research questions and discuss the technical challenges associated with ecotremology studies.

“…The different colours are the complementary results of substances that absorb a specific electromagnetic wavelength subtracting from the full spectrum of visible component of the light (which varies according to the taxon). At the same time, acoustic signals are the result of the vibration of a medium (e.g., air and water) (Shambaugh, 1930;Sturm et al, 2019), and olfactory signals are the interception of chemical molecules released by liquid, solid and gaseous substances (e.g., Page et al, 2011).…”

Vivoscape, from Latin ‘vivo’ (living) and the English ‘scape’ (shape and form of a place) is presented as a new ecosemiotic agency that integrates the interactions between biological and ecological components of a taxon with the environment. According to this model, the interactions between species and the environment are fused into a new functional unity driven by external and internal events (vivoevents). Sensorial and relational channels are used by a taxon to sense external energy gradients, matter, information and to return actions and proactions in an external operational environment. The eco-field model is suggested as the functional ecosemiotic mechanism associated with each vivoevent.

“…The probability that the emitted signal is intercepted by eavesdroppers does not increase only with the number of potential receivers, but also with the distance the signal travels through the habitat. The active space (i.e., effective range) of vibrational signals has been defined as the "area in which the signal amplitude is sufficiently above the detection threshold of potential receivers to have an effect on their behavioral response" (Mazzoni et al, 2014;Šturm et al, 2019). Signal active space therefore depends, on the one hand, on intrinsic factors like the signal amplitude at the source (i.e., "loudness" of the signaller) and the sensitivity of a receiver's vibroreceptors, and, on the other hand, on environmental factors like attenuation of the signal during the transmission through the substrate and the amplitude of interfering background noise.…”

“…It is generally assumed that for plant-dwelling animals the active space of vibrational signals is limited to the plant on which the animal is signaling. However, at least in meadows, the effective range also extends to the neighboring plants connected by roots and touching leaves (Čokl and Virant-Doberlet, 2003;Šturm et al, 2019) and even across a several-cm-wide air gap between overlapping leaves (Eriksson et al, 2011). Moreover, many small plant-dwelling insects increase the effective range of their vibrational signals using the behavioral strategy "fly/jump-call, " where they randomly move through the habitat and emit vibrational signals from different plants (e.g., Šturm et al, 2019).…”

Predator-Prey Interactions and Eavesdropping in Vibrational Communication Networks

Due to human perceptional bias in favor of airborne sounds, substrate-borne vibrational signaling has been traditionally regarded as a highly specialized, inherently short-range and, consequently, a private communication channel, free from eavesdropping by sexual competitors and predators. In this review, we synthesize current knowledge pertinent to the view that most animals live in a rich vibratory world, where vibrational information is available to unintended receivers. In recent years, we realized that vibrational signaling is one of the oldest and taxonomically most widespread forms of communication by mechanical waves and that receptors detecting substrate vibrations are ubiquitous. In nature, substrate vibrations are reliable source of information readily available to all members of the animal community able to detect them. Viewing vibrational communication in more relevant ecological context reveals that animals relying on substrate vibrations live in complex communication networks. Long evolutionary history of this communication channel is reflected in varied and sophisticated predator-prey interactions guided by substrate-borne vibrations. Eavesdropping and exploitation of vibrational signals used in sexual communication have been so far largely neglected; however, existing studies show that generalist arthropod predators can intercept such signals emitted by insects to obtain information about prey availability and use that information when making foraging decisions. Moreover, males which advertise themselves for longer periods than females and with vibrational signals of higher amplitude face higher predation risk. It is likely that eavesdropping and exploitation of vibrational signals are major drivers in the evolution taking place in the vibratory world and we believe that studies of interspecific interactions guided by substrate vibrations will, in the future, offer numerous opportunities to unravel mechanisms that are central to understanding behavior in general.
