Securing ecosystem functions is challenging, yet common priority in conservation efforts. While marine parks aim to meet this challenge by regulating fishing through zoning plans, their effectiveness hinges on compliance levels and may respond changes practices.

Coral reefs are in global decline. Reversing this trend is a primary management objective but doing so depends on understanding what keeps desirable states (ie “functional”). Although there evidence that coral thrive under certain conditions (eg moderate water temperatures, limited fishing pressure), the dynamic processes promote ecosystem functioning and its internal drivers community structure) poorly defined explored. Specifically, despite decades of research suggesting positive relationship between biodiversity across biomes, few studies have explored reef systems. We propose practical definition functioning, centered eight complementary ecological processes: calcium carbonate production bioerosion, herbivory, secondary predation, nutrient uptake release. Connecting species niches, functional diversity communities, rates key can provide novel, quantitative dependence communities will chart transition Anthropocene. This contribute urgently needed guidance for these important ecosystems.

Accurate, rapid, and comprehensive biodiversity assessments are critical for investigating ecological processes supporting conservation efforts. Environmental DNA (eDNA) surveys show promise as a way to effectively characterize fine-scale patterns of community composition. We tested whether single PCR survey eDNA in seawater using broad metazoan primer could identify differences composition between five adjacent habitats at 19 sites across tropical Caribbean bay Panama. paired this effort with visual fish compare methods conspicuous taxonomic group. revealed tremendous diversity animals (8,586 operational units), including many small taxa that would be undetected traditional situ surveys.

The Mediterranean Sea, a biodiversity hotspot, faces significant threats from non-indigenous species (NIS), which drive changes. Over the past century, introduction of NIS has accelerated due to maritime traffic, aquaculture, and interoceanic canals, fostering biological invasions. Marine protected areas (MPAs), established preserve biodiversity, are increasingly impacted. This review quantified characterized French MPAs, analyzing macroalgae distribution based on existing literature authors’ observations. Results revealed widespread occurrence, with highest richness in strictly regulated MPAs; their proximity large harbors highlights paramount importance pathways. In addition, there is knowledge gap regarding within complicating efforts monitor study these effectively. These findings highlight challenges monitoring managing invasions urgent need for controlling primary secondary invasion pathways, outside international collaboration control them, enhanced funding monitoring. Without adaptive management, even MPAs vulnerable escalating impacts invasive species.

Marine protected areas (MPAs) are globally important environmental management tools that provide protection from the effects of human exploitation and activities, supporting conservation marine biological diversity, habitats, ecosystems processes they host, as well resources in a broad sense. Consequently, also expected to manage enhance ecosystem services material, non-material, consumptive non-consumptive goods, benefits for humans. There is however certain confusion on what constitutes an service, it not always easy distinguish between them societal benefits. The main nuance service aptitude has or develops naturally consequence action, manifests through its own properties (productivity, stability, quality key parameters, etc.), while benefit economic other profitability (emotional, educational, scientific, etc.) humans obtain said quality.

Mapping habitats is essential to assist strategic decisions regarding the use and protection of coral reefs. Coupled with machine learning (ML) algorithms, remote sensing has allowed detailed mapping reefs at meaningful scales. Here we integrated WorldView-3 Landsat-8 imagery ML techniques produce a map suitable for occurrence model species, hydrocoral Millepora alcicornis, in located inside marine protected areas Northeast Brazil.
