... Emerging research shows that networks pretrained on unrelated terrestrial bioacoustic data transfer well to similar bioacoustic domains, enabling few-shot learning [9]. However, the ability of pretrained bioacoustic networks to transfer to highly novel domains, such as aquatic environments, is largely untested [14]. Substantial domain shifts may require the development of novel pretrained networks to achieve accurate few-shot transfer learning. ...

Some works focused on analysis and detection of fish based applications to video modality (Hsu et al. 2025;Stobart et al. 2025;Jahanbakht et al. 2023). Underwater video transmission is actively researched in works like Hegazy et al. (2021), Zheng et al. (2024b), Qi et al. (2024) and Smolyaninov et al. (2024). ...

... Reef. Despite the limited direct human pressures on CSMP reefs, they are increasingly being exposed to the effects of climate change with seven major coral bleaching events recorded in the CSMP in the past two decades (2002, 2004, 2016, 2017, 2020, 2021 and 2022), with five of these bleaching events occurring in the past eight years (Oxley et al. 2004, Harrison et al. 2018, Hoey et al. 2020 These recurrent bleaching events have caused considerable declines in coral cover across CSMP reefs, although there was considerable variation in the change in coral cover among individual reefs (Hoey et al. 2021(Hoey et al. , 2023 Despite the cultural and ecological significance of Ashmore and Boot Reefs our understanding of the habitats (both shallow and deep) within these reefs, the biodiversity they support, and the status of culturally significant species is limited. ...

... However, many areas are unsampled or undersampled within this enormous range, and given the uncertainty of morphological identification, they require genotyping to confirm identity. Additionally, a significant structure characterizes verified T. maxima populations across this vast range, and deep divisions may indicate incipient species formation ( [49], Figure 4). While T. maxima populations have been well studied in the western IO, Indo-Malay region, and Western Pacific, they have been little surveyed along and off the coastline of Western Australia in the eastern IO until now [35] (Figure 5). ...

... These organisms often occur in great numbers, have the capacity to exploit microscopic food sources, and exhibit rapid growth and turnover, giving them an important role in connecting various compartments of food webs (Barnes et al., 2016;Baxter et al., 2005;Potapov, 2022). Yet, due to their small size, they are often difficult to monitor and, concerningly, small consumers may be particularly vulnerable to anthropogenic impacts (Brandl et al., 2024;Koltz, Burkle, et al., 2018;Pollierer et al., 2023;Ripple et al., 2017;Wagner et al., 2021). Understanding the pathways, pace, and efficiency with which these organisms make essential elements available to larger consumers requires not only a detailed inventory of the small consumer species that are present but also a holistic understanding of their internal food web structure, their size structure, and the life history and physiology of the dominant species Trebilco et al., 2013;White et al., 2007). ...

... It has been shown that gravity diminishes the effectiveness of marine reserves at sustaining reef fish biomass and the presence of top predators, even where compliance with reserve rules is high [47]. It is also strongly related to biomass production and turnover in fish communities [3], and more importantly, to the fisheries' impact on fish biomass [48,62]. ...

Functional diversity shapes the stability of reef fish biomass under global change

... For each community, we characterized three aspects of environmental variability that capture (i) the linear trend in sea surface temperature through time (hereafter SST change); (ii) the temporal variability in SST caused by increasingly frequent marine heatwaves (hereafter CV SST ) and (iii) the temporal variability in marine primary productivity, measured by chlorophyll a content (hereafter CV Chlorophyll ), as it can directly influence the stability of fish communities [46]. We assessed the intensity of human pressures using the human gravity index, which integrates both reef accessibility and human population density, providing a relevant proxy of biomass depletion by fisheries on shallow reef ecosystems [47,48]. We estimated four facets of functional diversity (i.e. ...

... These seamounts possess diverse marine habitats including shallow coral reefs, their associated lagoons, coral bommies and deep mesophotic to rariphotic coral ecosystems (Ceccarelli 2011;Ceccarelli et al. 2013;Muir et al. 2015;Englebert et al. 2017;Baldwin et al. 2018). Recent ecological monitoring and baseline surveys have begun to establish knowledge of shallow coral reefs in the CSMP (Ayling and Ayling 1985;Ceccarelli et al. 2008;Hoey et al. 2023), but much of the region's biodiversity (especially in deeper waters; Beaman et al. 2016;Bridge et al. 2019;Galbraith, Cresswell, et al. 2022; FIGURE 1 | Location of the Coral Sea Marine Park (CSMP), offshore from the Great Barrier Reef, east coast Australia.

... According to previous research by Putra et al. (2020b), the Acanthuridae family represented more than 70% of eroding EAM and removed nearly 70% of daily EAM productivity in the coral ecosystem.
