TLDR
Though the distribution patterns reported here should be useful for the at-sea conservation of this endangered species, future research should focus on performing year-round tracking to map the species' distribution during the non-breeding period and gathering multi-year tracking information to understand the effect of inter-annual environmental stochasticity on the foraging choices and trophic habits of the species.About:

TL;DR: In this paper, the authors highlight research advances on the main threats for petrels (invasive species at breeding grounds, bycatch, overfishing, light pollution, climate change, and pollution) and propose an ambitious goal to reverse at least some of these six main threats, through active efforts such as restoring island habitats, improving policies and regulations at global and regional levels, and engaging local communities in conservation efforts.

Foraging areas, offshore habitat use, and colony overlap by incubating Leach's storm-petrels Oceanodroma leucorhoa in the Northwest Atlantic.

TL;DR: Future work should prioritize modelling efforts to incorporate information on relative predation risk at colonies, spatially explicit risks at-sea on the breeding and wintering grounds, effects of climate and marine ecosystem change, as well as lethal and sub-lethal effects of environmental contaminants, to better understand drivers of Leach’s storm-petrel populations trends in Atlantic Canada.

Ontogenic changes in habitat and trophic ecology in the Antarctic squid Kondakovia longimana derived from isotopic analysis on beaks
José P. Queirós,José P. Queirós,Yves Cherel,Filipe R. Ceia,Ana Hilário,Jim Roberts,José C. Xavier,José C. Xavier +7 more
TL;DR: The results suggested that the upper beak is the best beak to study ontogenetic shifts, mainly in initial stages of the cephalopods’ life, presenting lower values of δ15N than the lower beak.

Metabarcoding, stables isotopes, and tracking: unraveling the trophic ecology of a winter-breeding storm petrel (Hydrobates castro) with a multimethod approach

TL;DR: Overall, both sexes of Madeiran storm petrels exhibited a similar trophic ecology and diet during the breeding season, however, intersexual differences occurred during the non-breeding season, when females showed significantly lower nitrogen isotopic ratios than males (in 2016).
Journal ArticleDOI
High-resolution multi-marker DNA metabarcoding reveals sexual dietary differentiation in a bird with minor dimorphism.
TL;DR: The results suggest that dietary sexual differentiation in birds may be more widespread than recognized at present and that multi‐marker DNA metabarcoding is a particularly powerful tool to unveiling such differences.

A protocol for data exploration to avoid common statistical problems
TL;DR: A protocol for data exploration is provided; current tools to detect outliers, heterogeneity of variance, collinearity, dependence of observations, problems with interactions, double zeros in multivariate analysis, zero inflation in generalized linear modelling, and the correct type of relationships between dependent and independent variables are discussed; and advice on how to address these problems when they arise is provided.

Source partitioning using stable isotopes: coping with too much variation.
TL;DR: This work outlines a framework that builds on recently published Bayesian isotopic mixing models and presents a new open source R package, SIAR, to allow for continued and rapid development of this core model into an all-encompassing single analysis suite for stable isotope research.
