Sponge microbial communities play a crucial role in marine ecosystem functioning and serve as a rich source of bioactive compounds. While host identity is recognised as a major determinant of microbiome diversity, the underlying evolutionary mechanisms remain poorly understood. This study aimed to comprehensively assess phylosymbiosis patterns within the sponge family Petrosiidae. In total 21 sponge species, collected across a...

Coastal urbanization has significantly degraded coral reef habitats worldwide, often driving shifts from coral to algal dominance. Quantifying fish herbivory, a key ecological process mitigating such transitions, is essential for understanding reef health, functioning, and resilience. This study examined herbivory rates (bites multiplied by fish biomass) across five fish functional groups (detritivores, croppers, browsers, scr...

Sponges are one of the oldest lineages of animals on Earth and play key roles in shaping marine ecosystems. They are diverse, with more than 9600 species known to science, and come in a wide range of shapes, sizes, and colours. Sponges are, furthermore, known to host diverse communities of microbial symbionts, which play important roles in their physiology and ecology. In the present study, we sampled prokaryotic communities f...

It is widely recognized that humanity is currently facing multiple planetary crises, including the widespread loss of biodiversity and a rapidly changing climate. The impacts of these crises are often far reaching and threaten food security (SDG goal two: zero hunger). Small-scale fisheries are estimated to provide livelihoods for over one hundred million people and sustenance for approximately one billion people but face a pl...
