Paraglacial lagoons of Svalbard: emerging ecosystems at the Arctic Land-Sea interface

Rapid Arctic glacier retreat is fundamentally reshaping coastal landscapes, creating novel aquatic habitats, particularly paraglacial lagoons. In Svalbard, these systems are expanding, yet remain understudied despite their growing ecological and biogeochemical significance. This synthesis integrates geomorphological, hydrological, ecological, and biogeochemical perspectives, revealing a developmental continuum from glacier-influenced basins to more stable lagoons exhibiting dynamic conditions and diverse communities.

Oarfish diet question!! What kind of squid do they eat?

The elusive diet of oarfish remains a subject of ongoing scientific inquiry. While observations confirm squid as a primary food source, specific species remain largely undocumented—a challenge for artists seeking accurate representation. Empirical evidence suggests oarfish opportunistically consume various deep-sea squid, likely prioritizing those encountered at their foraging depths. Sculptors aiming for detail might consider representing a generic, deep-water squid morphology rather than a specific, definitively validated species.

Spotted in Friday Harbor, WA. Is this a decorator crab?

A fascinating observation from Friday Harbor, Washington, has sparked discussion regarding a potential decorator crab sighting. Submitted by /u/hikingbotanist, the video depicts two unique crustaceans observed amongst a population of shrimp along the pier. While initial iNaturalist identification suggests a decorator crab, discrepancies with existing imagery prompt further investigation. This observation highlights the ongoing need for robust species identification and underscores the interconnectedness of marine ecosystems, as explored in our recent article, "The world agreed to protect 30% of the ocean by 2030."

Ecological patterns of trace and essential metal bioaccumulation in marine fish from the Gulf of California, Mexico

A new study from World Data Ocean examines ecological patterns of trace and essential metal bioaccumulation in marine fish from the Gulf of California, Mexico. Researchers evaluated concentrations of eleven elements—including arsenic, selenium, and uranium—across three fish species from distinct feeding guilds at two locations, revealing significant variability linked to species ecology, regional geology, and historical mining activity. Notably, selenium exhibited high bioaccumulation, while arsenic concentrations displayed interspecific differences.

Correction: Gray whales (Eschrichtius robustus) in San Francisco Bay experience high mortality and have limited affiliation to known foraging groups

Recent data reveal concerning mortality rates among gray whales ( *Eschrichtius robustus* ) within San Francisco Bay, coupled with a notable lack of association with established foraging groups. This observation presents a significant challenge to understanding population dynamics and conservation strategies. Our analysis, based on longitudinal tracking, underscores the need for further investigation into the factors contributing to this trend.

Tourism and coastal fisheries interaction: impacts and mechanism on social-ecological coastal ecosystems

Coastal ecosystems face a complex interplay between tourism and fisheries, both vital for livelihoods and local development. While tourism is often proposed as a sustainable alternative to overexploited fisheries, the precise nature of this interaction remains unclear. A recent scoping review of 317 articles reveals a growing body of research examining these impacts and underlying mechanisms. Findings suggest tourism can either increase or decrease fishing pressure, depending on governance structures and livelihood shifts.

Editorial: The threat of invasive alien species and the challenge of climate change

## Editorial: The Threat of Invasive Alien Species and the Challenge of Climate Change The escalating impacts of climate change are not occurring in isolation; they are synergistically amplifying the threat posed by invasive alien species. Altered ocean temperatures, shifting currents, and increased storm frequency create unprecedented opportunities for non-native organisms to establish and proliferate, disrupting fragile marine ecosystems. Addressing this complex interplay demands integrated data and rigorous analysis.
