Coastal urbanization-related stressors affect fish herbivory in the Spermonde Archipelago, Indonesia

Frontiers in Marine Science, Journal Year: 2025, Volume and Issue: 12

Published: March 6, 2025

Coastal urbanization has significantly degraded coral reef habitats worldwide, often driving shifts from to algal dominance. Quantifying fish herbivory, a key ecological process mitigating such transitions, is essential for understanding health, functioning, and resilience. This study examined herbivory rates (bites multiplied by biomass) across five functional groups (detritivores, croppers, browsers, scrapers, excavators) in relation conditions along gradient of urban influence the Spermonde Archipelago, Indonesia. Herbivory generally increased inshore offshore sites, with notable differences among groups. Cropper scraper varied while detritivore excavator were consistent. Browser was only observed at most site, highlighting potential vulnerability browsing function near centers. Environmental factors influenced distinct ways. Detritivore higher on reefs lower rugosity, likely due sediment accumulation flatter substrates. all herbivorous fish, scrapers excavators individually, strongly correlated organic matter content turf algae sediments, underscoring importance food quality shaping dynamics. Experimental manipulation sediments (clearing vs . control) did not affect rates, suggesting that effects are main driver patterns studied sites. Preserving taxonomic diversity critical maintaining resilience amidst increasing local stressors.

A Self‐powered Triboelectric Coral‐Like Sensor Integrated Buoy for Irregular and Ultra‐Low Frequency Ocean Wave Monitoring

Advanced Materials Technologies, Journal Year: 2021, Volume and Issue: 7(6)

Published: Dec. 3, 2021

Abstract The design of efficient ocean wave sensors for monitoring the marine environment and revealing dynamic changes has been a major challenge. In this study, self‐powered bionic coral sensor (BCWS) based on triboelectric nanogenerator is proposed. BCWS captures data, which are useful engineering construction, resource development, disaster warning. It mainly composed perceiving units (60 mm in length, 10 width, 1.5 thickness) encapsulated tentacles, fixation mechanism, buoyancy tray, counterweight mechanism. With help its bio‐inspired structural design, effectively improves signal response time sensitivity 3D perception information. particular, tentacles stimulated by load cause contact‐separation between fluorinated ethylene propylene conductive ink electrodes, thereby generating electric signals. This analysis experimental data reveals that perceives height, frequency, period, direction with millimeter accuracy. To demonstrate applicability stability BCWS, several potential functions illustrated, including controlling light emitting diodes, information ocean, assisting overboard rescue. results show provides an intelligent solution modern monitoring.

The Nexus between Tourism Activities and Environmental Degradation: Romanian Tourists’ Opinions

Sustainability, Journal Year: 2021, Volume and Issue: 13(16), P. 9210 - 9210

This paper aims to analyse the nexus between tourism activities, including tourists’ circulation, accommodation or entertainment, and environmental degradation. Consequently, conceptual framework captures complexity of environment, given that activities can be performed by tourists for depends on quality, and, consequently, we highlight impact biodiversity loss through pollution effects they generate, i.e., air pollution, water noise as well their contribution waste increase depletion natural resources. To achieve this goal, apply structural equation modelling based partial least squares analysis (PLS). The results opinions existence a direct significant degradation, with many implications consequences.

Make a difference: Choose artificial reefs over natural reefs to compensate for the environmental impacts of dive tourism

The Science of The Total Environment, Journal Year: 2023, Volume and Issue: 901, P. 165488 - 165488

Published: July 29, 2023

In the marine environment, natural reef habitats are amongst most threatened by human activities. Although reef-based ecotourism can benefit local economies, dive tourism damage sensitive habitats. One solution to managing conflicts between economic value of diving and its ecological threats is deployment artificial reefs near popular sites. We surveyed recreational divers assess divers' use, preference, perceptions versus found that more prefer in than habitats, with associated biodiversity reason for preferring appreciating shipwrecks ones. Despite our sample population being highly educated experienced, predominantly European divers, only 49 % them perceived as important or somewhat diverting pressure from Similarly, 13 respondents exhibited preference avoid coral protect them.

No trout about it: behavioural and transcriptional effects of long-term noise exposure in brook trout (Salvelinus fontinalis)

Canadian Journal of Fisheries and Aquatic Sciences, Journal Year: 2025, Volume and Issue: 82, P. 1 - 16

Published: Jan. 1, 2025

Exposure to acute noise sources can lead negative behavioural outcomes and fitness deficits in fishes, but it is unknown whether fish habituate chronic exposures. As underwater increases globally, understanding how long-term exposures affect behavioural, morphological, transcriptional measures of stress critical. We tested responses captive brook trout ( Salvelinus fontinalis) immediately after exposure a 2 weeks exposure. Behavioural tests quantified movements before, during, sound presentation, with morphological changes assessed through ears whole brains samples, respectively. Pre-control pre-experimental exhibited increased swimming distance velocity, the 2-week exposure, post-experimental showed no response while post-control group remained responsive. Post-experimental significant differences transcription levels genes involved neuroplastic, appetite, relative other groups. Together these results suggest that may appear unresponsive via metrics anthropogenic noises they still show at level possible effects.
