“…It is composed of natural abiotic ambient sounds (geophony; Kinda et al 2013, Mathias et al 2016, anthropogenic sounds (anthrophony; Hildebrand 2009) and sounds from marine fauna (biophony). The main contributors to biophony are cetaceans (Au & Hastings 2008), fishes (Amorim 2006, Rountree et al 2006, Luczkovich et al 2008) and benthic invertebrates (Patek 2001, Popper et al 2001, Coquereau et al 2016a). Benthic invertebrates emit a variety of isolated transient sounds that eventually create mass phenomena such as choruses.…”

Coastal soundscapes are dominated by broadband transient sounds primarily emitted by benthic invertebrates. These sounds are characterized by a very large dynamic of amplitude. The loudest ones propagate further and interfere with the detectability of benthic sounds by invading other more distant habitats. Acoustic diversity assessment is therefore biased when applying acoustic indices related to the signal's power. Here, we propose new acoustic indices (IDSS: indices of the diversity of spectral shape) capable of extracting the diversity of the benthic invertebrate biophony (BIB) despite interference from loud and abundant sounds. A passive acoustic ecological survey was conducted in a shallow Mediterranean bay with a small-scale mosaic of biocenosis. The sound pressure level and spectrum of the BIB revealed that the rocky fringe had the most powerful biophony, propagating up to 3680 m, thus 'invading' other habitats. However, these power-based indices failed to depict BIB diversity. The IDSS allowed us to discriminate BIB diversity despite the interfering rocky fringe biophony, including low-power sounds not depicted by traditional power-based methods. Four main categories of benthic invertebrates sounds (BIS) spectra were found. Two categories (high-power, peak frequencies ~3 to 4 kHz) were mainly linked to the rocky fringe. Their contribution to the diversity (56%) decreased with increasing distance to the fringe, where low-power BIS (peak frequencies above 15 kHz) predominantly contributed to the BIB (42%) and may be specific to coralligenous reefs. The IDSS enables a better characterization and quantification of BIB diversity and soundscape structure with a fine spatial resolution (~200 m).

“…More than 800 fishes from 109 families are known to produce sounds, though this is likely to be an underestimate (Rountree et al 2003). It is evident that most of these sounds are deliberate rather than incidental.…”

Sexual dimorphism of drumming muscles in European hake (Merluccius merluccius)

2010

Dissections of mature and non-mature European hake males and females (N=142) collected in waters off the western coast of Norway and in the Bay of Biscay (France) in 2004-2006 demonstrate for the first time that this gadoid species contains drumming muscles. There were differences in drumming muscles weight with body length, sex and maturity stage. This study shows that the difference between females and males is primarily manifested during the spawning season, seen both in the French and Norwegian samples. For the mature females the drumming muscles dry weight increases only slightly, if at all, with increase in total length. For mature males there is a corresponding rapid increase. There does not seem to be any consistent difference between the average dry weight of the drumming muscles in immature male and immature and mature female hake of the same length, tested on the Norwegian samples.Our results suggest that male hake, like the males of other gadoids studied, may produce sounds in the context of spawning.

“…Little brown bats make calls to communicate with each other. An example of such a call is when two bats are flying on a collision course during feeding (Rountree et al, 2002). The similarity between the mobile nodes in MANET and the bats in a colony is that both cannot see their peer ends.…”

Abstract:A mobile ad-hoc network (MANET) is a network of wireless nodes with high mobility. Mobile nodes change their position quickly in any direction and speed, and follow an infrastructure-less network. Although there are many mobility models and protocols available to find the path between any two nodes, the challenge in retaining the path still remains unchanged. In general, a permanent path between any source and destination does not exist because of the node mobility. Path retention is essential for certain applications like in the military, disaster and rescue operations where an infrastructureless network like MANET is only feasible. In this paper an algorithm named 'Animal Communication Strategy (ACS)' is proposed to improve path construction and retention based on animal behaviour. Most of the time animals are found aggregated in the form of clusters. The cluster may undergo dispersal, reformation and reunion due to sudden changes. Each and every animal, who is aware of the changes, will immediately take the responsibility of communicating with their neighbours in the cluster. This impressive and cooperative behaviour of animals was adopted in the ACS algorithm. ACS algorithm is tested for performance using NS2 simulator. The results show a significant improvement with ACS for the metrics packet loss, delay and overhead when compared to the existing protocol in MANET routing.
