Vibrational and acoustic communication in fishes: The overlooked overlap between the underwater vibroscape and soundscape

The Journal of the Acoustical Society of America, Journal Year: 2023, Volume and Issue: 154(4), P. 2708 - 2720

Substrate-borne communication via mechanical waves is widespread throughout the animal kingdom but has not been intensively studied in fishes. Families such as salmonids and sculpins have documented to produce vibratory signals. However, it likely that fish taxa on or close substrate acoustic signals will also a component their signal due proximity substrates energy transfer between media. Fishes present an intriguing opportunity study vibrational communication, particularly context of production detection, detection range, how may complement replace It highly landscape, vibroscape, important sensory world, which certainly includes overlaps with soundscape. With wide range anthropogenic activities modifying underwater substrates, noise presents similar risks pollution for fishes depend communication. order understand noise, more empirical studies are required investigate role vibrations environment.

Paternal care regulates the timing, synchrony and success of hatching in a coral reef fish

Proceedings of the Royal Society B Biological Sciences, Journal Year: 2022, Volume and Issue: 289(1982)

Published: Sept. 13, 2022

In oviparous species, the timing of hatching is a crucial decision, but for developing embryos, assessing cues that indicate optimal time to hatch challenging. species with pre-hatching parental care, parents can assess environmental conditions and induce their offspring hatch. We provide first documentation regulation in coral reef fish, demonstrating male neon gobies (Elacatinus colini) directly regulate by removing embryos from clutch spitting hatchlings into water column. All synchronized within 2 h sunrise, regardless when eggs were laid. Paternally incubated hatched later development, more synchronously, had higher success than artificially shaken vibrational stimulus or not stimulated. Artificially displayed substantial plasticity times (range: 80-224 post-fertilization), suggesting males could respond heterogeneity modifying offspring. Finally, paternally smaller yolk sacs larger propulsive areas paternal effects on hatchling phenotypes may influence larval dispersal fitness. These findings highlight complexity fish care behaviour have important, currently unstudied, consequences population dynamics.

Timing decisions as the next frontier for collective intelligence

Trends in Ecology & Evolution, Journal Year: 2024, Volume and Issue: 39(10), P. 904 - 912

Published: July 3, 2024

The past decade has witnessed a growing interest in collective decision making, particularly the idea that groups can make more accurate decisions compared with individuals. However, nearly all research to date focused on spatial (e.g., food patches). Here, we highlight equally important, but severely understudied, realm of temporal making (i.e., about when perform an action). We illustrate differences between and decisions, including irreversibility time, cost asymmetries, speed–accuracy tradeoff, game theoretic dynamics. Given these fundamental differences, likely requires different mechanisms generate intelligence. Research should lead expanded understanding adaptiveness constraints living groups.

Effects of Light and Water Agitation on Hatching Processes in False Clownfish Amphiprion ocellaris

Journal of Experimental Zoology Part B Molecular and Developmental Evolution, Journal Year: 2024, Volume and Issue: unknown

Published: Sept. 12, 2024

ABSTRACT False clownfish ( Amphiprion ocellaris ) employ a hatching strategy regulated by environmental cues, wherein parents provide water flow to encourage embryos hatch after sunset on the day. Despite previous studies demonstrating necessity of complete darkness and agitation for hatching, regulatory mechanisms underlying these cues remain elusive. This study aimed investigate how affect secretion enzymes movements in false clownfish. Assessment chorion digestion live imaging Ca 2+ glands using GCaMP6s, indicator, revealed that stimulation triggers increasing levels gland cells. On other hand, primarily stimulated embryos, which led rupture their egg envelopes. These results suggest changes light environments following induce secrete provided stimulates movements. responses agitation, contribute rapid synchronous

Prehatch Calls and Coordinated Birth in Turtles

Ecology and Evolution, Journal Year: 2024, Volume and Issue: 14(10)

Published: Oct. 1, 2024

ABSTRACT Hatching synchronisation is widespread in oviparous taxa. It has been demonstrated that many species use sounds to coordinate synchronous hatching, being among archosaurs (birds and crocodilians). Recent studies have shown some turtle produce vocalisations from within the egg, but role of this behaviour synchronising hatch untested. The small amount information about sound production by embryos, limited a handful closely related species, precludes any inferences based on differences their ecology, reproductive phylogenetic context. With goal investigate if coordinated mediated within‐egg turtles, we recorded clutches six different species. selected animals present ecological niches belong distinct lineages at family level. We aimed understand: (1) what distribution vocal turtles; (2) asynchronous vocalise egg; (3) clutch size influences (4) calls follow signal. new evidence provides light current knowledge calls, challenging previous hypothesis are accidentally produced as side‐effects other behaviours.

Nocturnal parental care and the role of parents in hatching their eggs in the clown anemonefish

Ethology, Journal Year: 2023, Volume and Issue: 129(9), P. 479 - 488

Abstract Parental care is a critical component of many breeding systems that enhances both parent and offspring fitness. It widely recognized parental varies in quality quantity response to variation need, condition, ecological context. One context has been underexplored, however, the presence extensive at night, with studies focused on diurnal care. To fully understand evolution care, nocturnal must be accounted for. Here, we show exists clownfish Amphiprion percula , males females actively caring for night throughout embryo development during hatching within laboratory setting. At as day, continue dominant caregiver parents increase embryos mature. However, provide substantially more than day.

The first life-altering step for a fish is leaving the safety of its nest and hatching into big unknown. Researchers have long been fascinated with determining how embryos can discern when to hatch based on subtle cues from their environment.
