There are few generalizable patterns in ecology, with widespread observations and predictability. One possible pattern is the cumulative trophic theory, which consistently exhibits S-curves of biomass over level (TL) for 200 different marine ecosystems. But whether those persist some more distinct ecosystems, coral reefs, unclear. Coral reefs unique among representing global biodiversity hotspots providing crucial ecosystem services. They subject to many pressures, including both (e.g., climate ocean changes, warming, acidification) local overexploitation/overfishing, increase turbidity, bleaching, habitat destruction, invasive species) stressors. The analysis emergent features, such as S-curves, could represent a useful new analytical option that can also be implemented reefs. approach was applied 42 U.S. Pacific islands (Guam Commonwealth Northern Mariana Islands, American Samoa, Remote Islands Areas, Northwestern Main Hawaiian Islands), using data collected from fish surveys.

Millions of people around the world depend on ecosystem services produced by rocky and coral reef ecosystems, including nutrition, aesthetic value, coastal protection. Rocky reefs also contribute to critical global regional processes through cycling nitrogen, phosphorus, carbon. The increased stress experienced in Anthropocene threatens their ability provide vital services. This study investigates bundles services, that occur together, identify trade-offs synergies among reefs. To do this, we bring together estimates seven services: productivity, nitrogen cycling, phosphorus inorganic carbon nutritional We use correlations analysis understand between these cluster clusters with distinct suites or service bundles.

Abstract Function-based studies have opened a new chapter in our understanding of coral reefs. Unfortunately, we are opening this as the world’s reefs rapidly transform. In context, one most important roles function-based is to inform reef conservation. At critical juncture, chance reflect on where come from, and going, functional ecology, with specific consideration what means for approaches conserving As focal examples, examine role corals reefs, practice culling crown-of-thorns starfish, from perspective. We also consider how papers special issue build current understanding. Ultimately, highlight robust scientific investigation, based an ecosystem functions, will be key helping us navigate through crisis.

Consumers play an important role in biogeochemical cycles through the consumption and release of essential elements such as carbon (C), nitrogen (N), phosphorus (P). Indeed, a large proportion consumed are released into environment inorganic (i.e. excretion) or organic form egestion). On coral reefs, fishes represent bulk consumer biomass thus key recycling nutrients. In recent years, excretion rates have been studied intensively, but less is known about rate quality reef fish egestion. this study, we quantify elemental contents feces, estimate absorption efficiencies compare egestion for 51 species. We show that concentrations decrease remarkably little from food to feces. This due extremely low efficiencies, resulting amounts energy Moreover, while feces varies across trophic guilds, it remains highly variable within guilds. Finally, demonstrate N P outweighs amount nutrients recycled excretion. Our study highlights need incorporate animal assessments ecosystem functioning web structure.

Coral reef fisheries supply nutritious catch to tropical coastal communities, where the quality of seafood is determined by both rate biomass production and nutritional value fishes. Yet our understanding typically uses targets total fish rather than individual growth (i.e. production) nutrient content fish), limiting ability management sustain productivity catches. Here, we use modelled coefficients concentrations develop a new metric coral We then evaluate this with underwater visual surveys assemblages from four countries examine food webs. Species' were associated nutrients that vary body size (calcium, iron, selenium zinc), but not density.

Abstract The emergence of functional ecology has changed the focus ecological research from investigating patterns species diversity to understanding how traits relate specific processes generating these patterns. Traits, and can be shared driven by distantly related taxonomic groups. Crossing boundaries among groups is still a challenge critical knowledge frontier in ecology. A cross‐taxa approach, merging trait data across groups, could fill this gap. In context, functionally analogous traits, that may have distinct ontogenetic origins yet represent similar processes, comprise an important recent advance However, which taxa (be them or not) been used with multiple taxa, whether (and how) combined, needs elucidated.

The amount of ocean protected from fishing and other human impacts has often been used as a metric conservation progress. However, protection efforts have highly variable outcomes that depend on local conditions, which makes it difficult to quantify what coral reef date actually achieved at global scale. Here, we develop predictive model how conditions influence ~2,600 sites across 44 ecoregions, much more fish biomass there is reefs compared modeled scenario with no protection. Under the assumptions our model, study reveals without existing would be ~10% less reefs. Thus, estimate led approximately 1 in every 10 kg biomass.
