“…Our results, therefore, provide direct insights into population‐level energy use strategies by investigating EE and the functional responses of fishes to changes in habitat quality – shedding light on the processes that mediate competitive interactions between the two model species (Brandl et al., 2023 ). Ultimately, combining approaches to assess energy flows across trophic levels and ecosystem scales will help to paint a more holistic picture of how energy moves through aquatic food webs (Robinson et al., 2023 ).…”

Unveiling the intricate relationships between animal movement ecology, feeding behavior, and internal energy budgeting is crucial for a comprehensive understanding of ecosystem functioning, especially on coral reefs under significant anthropogenic stress. Here, herbivorous fishes play a vital role as mediators between algae growth and coral recruitment. Our research examines the feeding preferences, bite rates, inter‐bite distances, and foraging energy expenditure of the Brown surgeonfish (Acanthurus nigrofuscus) and the Yellowtail tang (Zebrasoma xanthurum) within the fish community on a Red Sea coral reef. To this end, we used advanced methods such as remote underwater stereo‐video, AI‐driven object recognition, species classification, and 3D tracking. Despite their comparatively low biomass, the two surgeonfish species significantly influence grazing pressure on the studied coral reef. A. nigrofuscus exhibits specialized feeding preferences and Z. xanthurum a more generalist approach, highlighting niche differentiation and their importance in maintaining reef ecosystem balance. Despite these differences in their foraging strategies, on a population level, both species achieve a similar level of energy efficiency. This study highlights the transformative potential of cutting‐edge technologies in revealing the functional feeding traits and energy utilization of keystone species. It facilitates the detailed mapping of energy seascapes, guiding targeted conservation efforts to enhance ecosystem health and biodiversity.

Amidst escalating threats to coral reefs during the Anthropocene era, an urgent call emerges for a holistic strategy that seamlessly integrates Sustainable Development Goals (SDGs), ensuring the conservation and sustainable development of these vital ecosystems. Employing an interdisciplinary lens, this chapter delves into the current state of coral reefs, shedding light on the critical need for immediate action. The study emphasizes the transformative potential of SDGs as a guiding framework for policies and initiatives aimed at fortifying resilient ecosystems and uplifting the communities intricately tied to coral reef ecosystems. Drawing on diverse case studies and successful conservation models, this chapter discerns key strategies essential for realizing SDGs in the intricate context of coral reefs. The synthesis of ecological and socio-economic perspectives contributes to a nuanced understanding of the multifaceted challenges and opportunities entwined in securing the sustainability of coral reefs within the Anthropocene. The study underscores the imperativeness of collaborative efforts, innovative solutions, and policy coherence to effectively navigate the intricate issues surrounding coral reefs, offering a blueprint for the integration of SDGs into practical conservation and sustainable development initiatives. As coral reefs teeter on the brink of irreversible decline, this research advocates for a comprehensive and dynamic approach that transcends disciplinary boundaries, promoting the vitality of these ecosystems and the well-being of the communities reliant upon them.
