Modeling archaeological site erosion often depends on regional databases that record sites accurately but with variable precision. This study examines the impact of sea-level rise (SLR) 10 in Quoddy Region Maine through comparing models and field observations. Sites were categorized as low, mid, or high priority for excavation based exposure to tides. These model results compared reports condition evaluate accuracy modeling SLR an indicator application developing prioritization protocols investigations. Models current sea level scenarios broadly underestimate degree reported by observations because not all locations recorded at precision required analysis. emphasizes importance audits enable large-scale urgently threatened sites.

Retrospective datasets offer essential context for conservation by revealing species’ ecological roles before industrial-era human impacts. We analysed isotopic compositions of pre-industrial and modern sea otters ( Enhydra lutris ) to reconstruct pre-extirpation ecology insights management. Our study focuses on southeast Alaska (SEAK), where are recolonizing, northern Oregon, translocations being considered. measured bulk bone collagen δ 13 C 15 N values amino acid extirpated from archaeological contexts, vibrissae SEAK otters. compare these results with published data potential prey additional datasets. In SEAK, our show otter populations consumed infaunal bivalves used soft-sediment (33%) kelp forest habitats (67%), sub-regional variation. anticipate current will expand into this historical niche, conflict regional traditional/subsistence bivalve fisheries persist. indicate past consumption low trophic level invertebrates a stronger reliance forests (88%) rather than habitats, highlighting the importance future translocations. work exemplifies value in informing strategies recovering species.

Abstract The Pacific cod (Gadus macrocephalus) fishery was closed in 2020 after a rapid decline biomass caused by the marine heat waves of 2014–2019. are exceptionally thermally sensitive and management this is now challenged increasingly unpredictable climate conditions. Fisheries monitoring critical for readiness, but short-term data may be inadequate recognizing anticipating change under changes. We propose an interdisciplinary, historical ecology framework that looks to long-term records (local traditional knowledge, history, archaeology, paleoclimatology) capture long range ecological variability provide context management. In order connect contemporary fisheries management, must built on common vocabulary understanding key metrics used stock assessments. Here, we derived from assessment synthesize information relevant effects past warming periods populations across Gulf Alaska Bering Sea. This case study provides thinking about how use these rapidly changing
