Within the northern Red Sea, coral reef communities appear to be faring relatively better than global trends and continue to exhibit remarkable diversity and thermal tolerance. However, recent reports of coral bleaching in the region highlight the urgent need for comprehensive ecological surveys to provide a baseline for long-term monitoring of biodiversity and potential species loss. This field report aims to support the tracking of diversity and growth form distributions of scleractinian corals at two reef sites at Mangrove Bay, El Qoseir, Egypt.

As a result of our 2023 field survey, we identified a total of 68 species across 29 genera and 14 families, spanning six reef habitats - three per study site - at two study locations (sheltered and current-exposed), with depths ranging from 0 to 9.5 m. We found that both scleractinian coral diversity and coral growth forms varied amongst the six habitats. Branching corals were found in each habitat, but were particularly abundant at the current-exposed reef edge, where they covered 67% of the habitat. Encrusting and massive corals became more prevalent with increasing depth at both study sites, with massive corals covering 72% at the sheltered deeper reef slope and encrusting corals covering 24% at the current-exposed deeper reef slope.

Understanding the feeding ecology of waterbirds is crucial for strengthening conservation efforts in vulnerable intertidal habitats. This study investigated the feeding behaviour and diet composition of waterbirds along the South West Johor Coast, Malaysia. Fieldwork was conducted in three coastal mudflats from November 2020 to May 2021, employing the direct observation technique. A total of 576 hours of observation were recorded, averaging 2 hours and 19 minutes per focal observation. Of 17 waterbird species recorded, only 11 species were included in the analysis based on sufficient data. The results revealed that waterbirds primarily consumed fish, molluscs, worms, crabs and unidentified prey, with fish comprising 25% of their overall diet. Feeding behaviour varied significantly by morphology traits, with larger waterbirds demonstrating higher feeding efficiency. Despite lower feeding rates and shorter feeding durations, larger species had a greater percentage of successful feeding attempts, indicating their superior ability to meet energy requirements. These findings provide crucial baseline data for understanding waterbird feeding ecology and highlight the importance of conserving the intertidal habitats.
