Negotiation of Parental Duties in Chick-Rearing Common Murres (Uria aalge) in Different Foraging Conditions

open access: yesFrontiers in Ecology and Evolution, 2020
Mates of biparental species share parental care but they are also predicted to try, within limits, to push for more offspring care from their partners.

Structure‐forward targeting of claudins with synthetic binders

open access: yesFEBS Letters, EarlyView.
Claudins form the paracellular barriers between epithelial and endothelial tissues at tight junctions and are targets for molecular binders with the goal of modulating barrier permeability. Claudin‐binding molecules are relevant in drug delivery or in altering claudin interactions with disease‐causing proteins.

Preliminary assessment of habitat characteristics of woodland caribou calving areas in the Claybelt region of Québec and Ontario, Canada

open access: yesRangifer, 2003
Woodland caribou (Rangifer tarandus caribou) require a diversity of forested habitats over large areas and may thus be particularly affected by the large-scale changes in the composition and age-class distribution of forest landscapes induced by the ...

Nutrient/TOR signaling controls adipose mitochondrial transcription factor A (TFAM) to regulate organismal growth in Drosophila

open access: yesFEBS Letters, EarlyView.
Animals must match their growth rate to available nutrients. We show that in Drosophila larvae, the nutrient‐sensing TOR kinase controls growth by regulating levels of TFAM, a key regulator of mitochondrial function, in the adipose tissue. When nutrients are abundant, high TOR activity suppresses TFAM, lowering mitochondrial bioenergetic activity and ...

European food availability databank based on household budget surveys

open access: yes, 2011
There is a need in Europe for sources of dietary data that would provide a regular flow of comparable nutrition information. In this context, the Data Food Networking (DAFNE) project has been developing a cost-effective food databank that allows ...

Liver organoids: modelling complexity in homeostasis and disease

open access: yesFEBS Letters, EarlyView.
Studying liver in vitro has been challenging because simple 2D cell cultures fail to capture liver's cellular and architectural complexity. To bridge this gap, scientists increasingly use organoids, 3D liver models which better mimic liver composition and function. This review examines recent advances in liver organoid complexity and realism, discusses

The availability, price, and marketing characteristics of organic foods and beverages: a comparative food environment assessment

open access: yesFrontiers in Sustainable Food Systems
BackgroundDemand for organic foods remains low, despite the potential of organic products to contribute to sustainable food systems. Food purchasing decisions are influenced by the food environment, yet no study has systematically evaluated food ...

Feeding Strategies of Brown Howler Monkeys in Response to Variations in Food Availability

open access: yesPLoS ONE, 2016
Primates display varying degrees of behavioral flexibility that allow them to adjust their diet to temporal changes in food availability. This trait might be critical for the survival of folivorous-frugivorous species inhabiting small forest fragments ...

Food Availability and Food Entitlements during the Chinese Great Leap Forward Famine: A dynamic panel data analysis (In French) [PDF]

open access: yes
The article aims at identifying socioeconomic factors which explain the Chinese famine of 1959-1961. The main hypothesis of this paper is that the radicalism of Great Leap Forward policies generated both a decline of agricultural output (availability ...
