Individual movement modeling expands the power of migratory species observations: North Atlantic right whale case study

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Understanding a population's distribution depends on observing the presence and movement of individuals throughout their range. For highly mobile marine species, these observations typically rely on high effort monitoring programs. Tracking enough individuals to understand trends in movement behavior is not always logistically feasible, and ...

Lipid correction of hydrogen stable isotope ratios in fish

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Lipids are known to affect stable isotope ratio of organisms, especially δ13C values, and simple arithmetic lipid‐correction procedures have been developed based on the carbon to nitrogen ratio (C : N) that is a proxy for lipid content. Equivalent issues will likely arise with the increasing use of hydrogen isotopes in ecology, but as yet no ...

Archaeological and Biogeochemical Investigation of Past Human Relationships With Now‐Endangered Fish Species: Lake Sturgeon and American Eel in Southern Ontario, Canada

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT This paper explores the historical ecology and biogeography of two fish species that are currently endangered in the North American Great Lakes region, that were of great importance to the Indigenous people in the region, and that are the focus of ongoing conservation efforts on the part of descendant communities: lake sturgeon (Acipenser ...

Stable Carbon and Nitrogen Isotope Analysis Explores Diverse Domestic Goose Management Practices in Medieval and Postmedieval Russia

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT Studying goose domestication through archaeological finds has been challenging due to the similar skeletal morphology of the European domestic goose and its wild progenitor, the greylag goose (Anser anser). We analyzed stable carbon (δ13C) and nitrogen (δ15N) isotopes from bone collagen of subfossil domestic and potentially domestic geese to ...

Overexploitation can counteract top‐down control and the paradox of enrichment in simple food chains

open access: yesOikos, EarlyView.
Because of its high abundance or its high feeding intensity, a consumer can overexploit its resource by consuming it on a shorter timescale than resource regeneration. While this short‐term overexploitation is widespread in nature, its general implications for biotic control patterns and ecosystem stability are not clear.
