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

International 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 ...

Identifying knowledge gaps about context dependency in freshwater species invasions

Oikos, EarlyView.
The abiotic template of freshwater ecosystems is being altered by human activity on a global scale, often promoting the establishment of new invasive taxa and increasing the likelihood of facilitation between invaders. These positive interactions represent a substantive threat to freshwater ecosystems by promoting the establishment and persistence of ...

THE ART OF WAR: PATTERNS AND MECHANISMS UNDERLYING PREDATOR-INDUCED PLASTICITY OF AMPHIBIANS [PDF]

, 2013
Organisms often employ phenotypic plasticity as a strategy to cope with variable environments. This is particularly true of predation threats, wherein prey induce defenses to reduce detection or capture by predators.

The importance of wild meat and freshwater fish for children's nutritional intake in the Congo Basin

People and Nature, EarlyView.
Abstract Wild meat and freshwater fish are widely consumed in the Congo Basin, but in some areas, they are at risk of disappearing due to unsustainable hunting and fishing and changes in their habitat. Wild meat is also at risk of being eliminated from local diets due to potential policy changes such as wild meat bans.
