An ensemble machine learning bioavailable strontium isoscape for Eastern Canada

FACETS
Bioavailable strontium isotope ratios (87Sr/86Sr) distribution across the landscape mainly follow the underlying lithology, making 87Sr/86Sr baseline maps (isoscapes) powerful tools for provenance studies.

Is Gillnet Prey Subsidizing Ontogenetic Diet Shifts and Early Weaning in Common Coastal Bottlenose Dolphins From the Southwestern Gulf of Mexico?

Fisheries Management and Ecology, EarlyView.
ABSTRACT Artisanal gillnet fisheries can concentrate prey and provide incidental food subsidies to marine predators, but their effects on early‐life foraging behavior and demography remain poorly resolved. The Alvarado bottlenose dolphin population that lives off the coast of Veracruz, Mexico, is well known for having chronic, frequent, and recurring ...

Data_Sheet_1_Estimates of woody biomass and mixed effects improve isoscape predictions across a northern mixed forest.docx

, 2023
Contemporary methods used to predict isotopic variation at regional scales have yet to include underlying distributions of the abundance of isotopic substrates.

Contrasting Food Web Dynamics Across Oceanographic Boundaries in Subarctic Pelagic Ecosystems

Fisheries Oceanography, EarlyView.
ABSTRACT Understanding the structure of pelagic food webs across multiple trophic levels is critical for elucidating species interactions, energy flow, and anthropogenic impacts on production. This study presents a comprehensive analysis of the eastern North Pacific pelagic food webs, focusing on the Gulf of Alaska (GoA) during late winter of 2019.

Stable Isotope Analyses of Yellowfin and Blackfin Tuna Eye Lenses Reveal Life History Patterns

Fisheries Oceanography, EarlyView.
ABSTRACT Spatial geography, ontogenetic movement, and trophic patterns of mobile species are key elements of species life history, and knowledge of them is critical for effective marine resource management. For yellowfin tuna (Thunnus albacares; YFT) and blackfin tuna (Thunnus atlanticus; BLFT), residency durations and ontogenetic movements in the Gulf

A strontium isoscape of Italy for provenance studies

Chemical Geology, 2022
We present a novel database of environmental and geological 87Sr/86Sr values (n = 1920) from Italy, using literature data and newly analysed samples, for provenance purposes. We collected both bioavailable and non-bioavailable (i.e. rocks and bulk soils) data to attain a broader view of the Sr isotope variability of the Italian peninsula.

Assessing the Reliability of Mobility Interpretation From a Multi-Isotope Hair Profile on a Traveling Individual

Frontiers in Ecology and Evolution, 2020
Forensic practitioners, archeologists, and ecologists increasingly use hair isotope profiles and isotope databases and maps to reconstruct the life history of unidentified individuals.

Groundwater Isoscapes for the Contiguous USA

, 2019
Water extracted from subsurface aquifers has been and continues to be a major source of drinking and irrigation water in locations around the world. Regional studies and global compilations have demonstrated that the stable H and O isotopic composition of groundwaters often differs from that of local precipitation and/or surface water resources due to ...

Dietary partitioning mediates species coexistence in the high seas area of northwest Pacific

Ecography, Volume 2026, Issue 9, September 2026.
Niche partitioning, manifesting along various axes of the ecological niche, is a fundamental mechanism mediating species coexistence in a system. However, the emergence of many species in marine ecosystems would face considerable constraints in achieving coexistence through spatiotemporal differentiation mechanisms under the framework of niche ...
