Insect communities of late Pleistocene steppe–tundra and Holocene boreal forest ecosystems in central Yukon Territory, Canada

Journal of Quaternary Science, EarlyView.
ABSTRACT Subfossil insect communities from the Quartz Creek site provide a detailed record of both Late Pleistocene steppe–tundra and Holocene boreal forest ecosystems in central Yukon Territory, Canada. Fifteen Pleistocene assemblages (marine isotope stages [MIS] 4 to 2) are dominated by steppe–tundra and dry‐tundra taxa, particularly the weevils ...

myo‐Inositol's role in laying hens’ active gastrointestinal microbiota: a strain comparison

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND myo‐Inositol (MI) is a cyclitol involved in cellular metabolism and phytate degradation, yet its influence on the gastrointestinal tract (GIT) microbiota of laying hens remains poorly understood. This study investigated the effects of graded dietary MI supplementation on the active GIT microbial communities of two commercial laying ...

Overview of the re‐evaluation of trace elements as nutritional feed additives in the European Union: characterization, safety, and efficacy

Journal of the Science of Food and Agriculture, EarlyView.
Abstract The re‐evaluation of feed additives in the European Union was outlined in the Regulation (EC) No 1831/2003. The primary objectives were to ensure safety and verify efficacy, as well as to update authorizations and phase out unsafe additives or those in which the industry expressed no interest.

Ringtail (Bassariscus astutus) survival in southwestern Oregon

The Journal of Wildlife Management, EarlyView.
We captured and monitored radio‐collared ringtails over 2 years to estimate monthly and annual survival rates. We found that annual survival rates were much higher within forested landscapes in Oregon than for populations in the southwestern United States.
