Are we ready to track climate‐driven shifts in marine species across international boundaries? ‐ A global survey of scientific bottom trawl data

Marine biota are redistributing at a rapid pace in response to climate change and shifting seascapes. While changes fish populations community structure threaten the sustainability of fisheries, our capacity adapt by tracking projecting marine species remains challenge due data discontinuities biological observations, lack availability, mismatch between real distributions. To assess extent this challenge, we review global status accessibility ongoing scientific bottom trawl surveys. In total, gathered metadata for 283,925 samples from 95 surveys conducted regularly 2001 2019. We identified that 59% collected not publicly available, highlighting availability is most important redistributions under change. Given primary purpose provide independent inform stock assessment commercially populations, further highlight single do cover full range main commercial demersal species.

Range edges of North American marine species are tracking temperature over decades

Global Change Biology, Год журнала: 2021, Номер 27(13), С. 3145 - 3156

ABSTRACT Understanding the dynamics of species range edges in modern era is key to addressing fundamental biogeographic questions about abiotic and biotic drivers distributions. Range are where colonization extirpation processes unfold, so these also important understand for effective natural resource management conservation. However, few studies date have analyzed time series edge positions context climate change, part because difficult detect. We first quantified 165 marine fishes invertebrates from three U.S. continental shelf regions using up five decades survey data a spatiotemporal model account sampling measurement variability. then whether those maintained their thermal niche—the temperatures found at position—over time. A large majority (88%) either summer or winter temperature extremes over study period, most both (76%), although not all shifted space. we numerous edges—particularly poleward region that experienced warming—that did shift all, further than predicted by alone, opposite direction expected, underscoring multiplicity factors drive changes positions. This suggests temperate largely same niche during periods rapid change provides blueprint testing what degree track general.

Timing and magnitude of climate‐driven range shifts in transboundary fish stocks challenge their management

Global Change Biology, Год журнала: 2022, Номер 28(7), С. 2312 - 2326

Опубликована: Янв. 18, 2022

Abstract Climate change is shifting the distribution of shared fish stocks between neighboring countries’ Exclusive Economic Zones (EEZs) and high seas. The timescale these transboundary shifts determines how climate will affect international fisheries governance. Here, we explore this by coupling a large ensemble simulation an Earth system model under emission scenario to dynamic population model. We show that 2030, 23% have shifted 78% world's EEZs experienced at least one stock. By end century, projections total 45% globally 81% waters with magnitude such reflected in changes catch proportion sharing global are projected experience average 59% stocks. Many countries highly dependent on for livelihood food security emerge as hotspots shifts.

Meanwhile, new anticipatory consider concerns associated uncertainties resilient change.

Sea temperature is the primary driver of recent and predicted fish community structure across Northeast Atlantic shelf seas

Global Change Biology, Год журнала: 2023, Номер 29(9), С. 2510 - 2521

Опубликована: Март 10, 2023

Climate change has strongly influenced the distribution and abundance of marine fish species, leading to concern about effects future climate on commercially harvested stocks. Understanding key drivers large-scale spatial variation across present-day assemblages enables predictions change. Here we present a unique analysis standardised data for 198 species from Northeast Atlantic collected by 23 surveys 31,502 sampling events between 2005 2018. Our analyses spatially comprehensive identified temperature as driver community structure region, followed salinity depth. We employed these environmental variables model how will affect both distributions individual local years 2050 2100 under multiple emissions scenarios. results consistently indicate that projected lead shifts in communities entire region. Overall, greatest community-level changes are predicted at locations with greater warming, most pronounced higher latitudes. Based results, suggest climate-driven warming widespread opportunities commercial fisheries

FISHGLOB_data: an integrated dataset of fish biodiversity sampled with scientific bottom-trawl surveys

Scientific Data, Год журнала: 2024, Номер 11(1)

Опубликована: Янв. 4, 2024

Scientific bottom-trawl surveys are ecological observation programs conducted along continental shelves and slopes of seas oceans that sample marine communities associated with the seafloor. These report taxa occurrence, abundance and/or weight in space time, contribute to fisheries management as well population biodiversity research. Bottom-trawl all over world represent a unique opportunity understand ocean biogeography, macroecology, global change. However, combining these data together for cross-ecosystem analyses remains challenging. Here, we present an integrated dataset 29 publicly available national waters 18 countries standardized pre-processed, covering total 2,170 sampled fish 216,548 hauls collected from 1963 2021. We describe processing steps create dataset, flags, standardization methods developed assist users conducting spatio-temporal stable regional survey footprints. The aim this is support research, conservation, context
