The value of ecosystem services in global marine kelp forests

Nature Communications, Journal Year: 2023, Volume and Issue: 14(1)

Published: April 18, 2023

Abstract While marine kelp forests have provided valuable ecosystem services for millennia, the global ecological and economic value of those is largely unresolved. Kelp are diminishing in many regions worldwide, efforts to manage these ecosystems hindered without accurate estimates that provide human societies. Here, we present a estimate potential three key - fisheries production, nutrient cycling, carbon removal by six major forest forming genera ( Ecklonia, Laminaria, Lessonia, Macrocystis, Nereocystis , Saccharina ). Each creates between $64,400 $147,100/hectare each year. Collectively, they generate $465 $562 billion/year with an average $500 billion. These values primarily driven production (mean $29,900, 904 Kg/Ha/year) nitrogen ($73,800, 657 Kg N/Ha/year), though also estimated sequester 4.91 megatons from atmosphere/year highlighting their as blue systems climate change mitigation. findings highlight society will facilitate better informed management conservation decisions.

Detecting areas with high social-ecological vulnerability (SEV) is essential to better inform management interventions for building resilience in coastal systems. The SEV framework, developed by the Intergovernmental Panel on Climate Change, a robust method identify of tropical systems climate change.

Studying functions on coral reefs: past perspectives, current conundrums, and future potential

Coral Reefs, Journal Year: 2024, Volume and Issue: 43(2), P. 281 - 297

Published: Feb. 24, 2024

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.

Abstract Setting appropriate conservation strategies in a multi-threat world is challenging goal, especially because of natural complexity and budget limitations that prevent effective management all ecosystems. Safeguarding the most threatened ecosystems requires accurate integrative quantification their vulnerability functioning, particularly potential loss species trait diversity which imperils functioning. However, magnitude threats associated biological responses both have high uncertainties.

Mean reef fish body size decreases towards warmer waters

Ecology Letters, Journal Year: 2024, Volume and Issue: 27(2)

Published: Feb. 1, 2024

Abstract Aquatic ectotherms often attain smaller body sizes at higher temperatures. By analysing ~15,000 coastal‐reef fish surveys across a 15°C spatial sea surface temperature (SST) gradient, we found that the mean length of in communities decreased by ~5% for each 1°C increase space, or 50% decrease from 14 to 29°C annual SST. Community size change was driven differential responses within trophic groups and temperature‐driven their relative abundance. Herbivores, invertivores planktivores became on average warmer temperatures, but no trend piscivores. Nearly 25% temperature‐related community attributable composition warmest sites, colder this <1% due being similarly sized. Our findings suggest small changes are associated with large sizes, important ecological implications.

Paired environmental DNA and dive surveys provide distinct but complementary snapshots of marine biodiversity in a temperate fjord

Environmental DNA, Journal Year: 2023, Volume and Issue: 5(3), P. 597 - 612

Published: April 20, 2023

Abstract Marine biodiversity is a key indicator of ecosystem health and can be assessed using variety methods, including environmental DNA (eDNA) sampling. However, the ecology eDNA in physically dynamic nearshore environments remains uncertain, particularly with regards to how stratifies depth. Here, we paired sampling dive surveys at six sites Knight Inlet, British Columbia, Canada. samples were collected from surface, midwater column bottom (8–25 m depth) each site, while focused on (benthic) habitat. Amplicon sequencing mitochondrial 12S rRNA gene (targeting fish) COI marine invertebrates algae) resolved significant differences community composition surface waters compared bottom. Differences by depth greater than across sites, dominated salmon ( Oncorhynchus spp.) rotifer DNA, largely Pacific herring, copepods, mussels. therefore, may not accurately capture benthic communities, systems high levels freshwater input such as coastal temperate fjords. Over small spatial scales, strong stratification, adding different depths more effective maximizing inferred diversity rather sites. In general, there was low overlap species detection between (less 10% for taxonomic group – fish, invertebrates, algae). observed clear strengths method provided better resolution, total diversity. These results suggest that two survey methods used tandem provide distinct complementary snapshots environment.
