Wildfire Emissions From European Boreal Fuels: Effects of Fuel Type and Moisture Content

Fire and Materials, EarlyView.
ABSTRACT The increasing severity of wildfires poses significant challenges through the release of greenhouse gases and other harmful gases and particles. Although field measurements exist, there is a lack of systematic data collection to understand the influence of moisture content on the particle and gas emissions of boreal fuels, particularly for ...

Under‐Explored Species, Breeds and Cell Types With Potential for Cultivated Meat Production

Food Bioengineering, EarlyView.
This graphical abstract illustrates how the strategic selection of overlooked cell lines from novel species and specific agricultural breeds can help overcome current manufacturing bottlenecks in cultivated meat production. The schematic links the concept of an ‘ideal cell line’ to four key bioprocessing and product advantages that can be optimised ...

Feathers in nest boxes do not prevent or delay nesting by Eastern Bluebirds ( Sialia sialis ), Tree Swallows ( Tachycineta bicolor ), or Carolina Chickadees ( Poecile carolinensis )

Journal of Field Ornithology
Many species of birds incorporate feathers into their cavity nests. The Fear of Feathers Hypothesis proposes that a major benefit of incorporating feathers into cavity nests is to trick other birds into thinking that a predation event occurred in the ...

Predicting origins of passerines migrating through Canadian migration monitoring stations using stable-hydrogen isotope analyses of feathers: a new tool for bird conservation

Avian Conservation and Ecology, 2015
The Canadian Migration Monitoring Network (CMMN) consists of standardized observation and migration count stations located largely along Canada's southern border.

Notable Impact of Paleotectonic Stress on Gold Mineralisation in the West Qinling Orogen

Geological Journal, EarlyView.
By applying fuzzy clustering and multiple inverse methods, we systematically processed the data of vein and fault slip in this ore deposit to reveal the transition of orogenic geological environment and paleotectonic stress field. Our research results show two different stress states: the northwest–southeast extensional stress field and the northeast ...

Trace element bioaccumulation in the plumage of common blackbirds (Turdus merula Linnaeus, 1758) from Agigea, Romania

Present Environment and Sustainable Development
The purpose of this research was to establish the baseline concentrations of thirteen trace elements (Cd, Co, Cr, Cu, Ni, Pb, Fe, Mg, Na, K, Sr, Ca, and Zn) in feathers of the common blackbird Turdus merula (n=9) at the Natura 2000 site “Marine Dunes ...

Homology and Potential Cellular and Molecular Mechanisms for the Development of Unique Feather Morphologies in Early Birds

Geosciences, 2012
At least two lineages of Mesozoic birds are known to have possessed a distinct feather morphotype for which there is no neornithine (modern) equivalent. The early stepwise evolution of apparently modern feathers occurred within Maniraptora, basal to the ...

Revisiting the Relationship Between Job Insecurity and Work Engagement: The Moderating Roles of Contract Type and Trait Negative Affectivity

Human Resource Development Quarterly, EarlyView.
ABSTRACT This study proposes and tests a curvilinear effect of job insecurity on work engagement, while also examining the moderating roles of employment contract type (permanent vs. temporary) and trait negative affectivity on this relationship. Utilizing two waves of time‐lagged data from a sample of 397 participants (273 permanent and 124 temporary ...

Conflict between cultural development and wildlife conservation: A potential threat to Reeves's pheasant (Syrmaticus reevesii)

Conservation Letters
Reeves's pheasant feathers are used to make headgears for the Chinese opera—Xiqu; however, this posed a considerable threat to the bird's population before it was banned from hunting/trade.

Hairs, feathers and fibres in Mesolithic contexts – recommendations for field archaeologists

Acta Academiae Artium Vilnensis
Microarchaeological research has drawn attention to new microscopic categories of finds such as charcoal and ash, archaeobotanical remains, and non-pollen palynomorphs, including textile fibres.
