Migratory microbiomes: the role of the gut microbiome in bird migration eco‐physiology

Journal of Avian Biology
Long‐distance bird migration is one of the most metabolically and immunologically challenging feats in the animal kingdom, with birds often needing to double their weight in a matter of days and facing increased exposure to novel pathogens.

Spiritual and religious information experiences: An Annual Review of Information Science and Technology (ARIST) paper

Journal of the Association for Information Science and Technology, EarlyView.
Abstract This chapter examines the contours of the religious and spiritual information experiences subfield through a review and content analysis of selected contributions from the past two decades in both information science and related fields. The research question that guides this review is: How have spirituality and religion been conceptualized in ...

Latitudinal distribution, migration, and testosterone levels in birds [PDF]

, 2008
Tropical bird species usually have lower testosterone (T) levels during breeding than temperate species. However, the potential mechanisms behind the positive interspecific correlation between T and latitude remain unexplored. In a comparative study of

Reduced Adult Neurogenesis in Humans Results From a Tradeoff Rather Than Direct Negative Selection

BioEssays, EarlyView.
Embryonic radial glia (RG) generate neurons, glial cells, and later adult neural stem cells, which sustain adult neurogenesis (top, left to right). Human‐specific genetic modifications (blue arrow), selected to boost early RG neurogenic activity, may lead to premature RG exhaustion and reduced adult neurogenesis in the human brain (bottom).

Accounting for Climate Change: A Temporal Analysis of the Literature

Business Strategy and the Environment, EarlyView.
ABSTRACT This study presents a systematic literature review of articles related to accounting for climate change. By adopting the theoretical lenses of the actor–network theory, this study investigates the primary actors influencing management research on accounting for climate change and how their roles have evolved over time considering major ...

Methods of quantitative and qualitative analysis of bird migration with a tracking radar [PDF]

Methods of analyzing bird migration by using tracking radar are discussed. The procedure for assessing the rate of bird passage is described. Three topics are presented concerning the grouping of nocturnal migrants, the velocity of migratory flight, and ...

Radial Mixing in Galactic Disks: The Effects of Disk Structure and Satellite Bombardment

, 2011
We use a suite of numerical simulations to investigate the mechanisms and effects of radial migration of stars in disk galaxies like the Milky Way (MW).

Brazilian Biomes as Promising Resources of Rhodotorula Yeasts for the Biotechnological Production of Carotenoids

Chemistry &Biodiversity, EarlyView.
ABSTRACT Yeasts belonging to the genus Rhodotorula are capable of synthesizing carotenoids, such as β‐carotene, γ‐carotene, torulene, torularodine, and astaxanthin. These carotenoids have been shown to offer health benefits to humans, such as immune system strengthening and a reduced risk of chronic degenerative diseases.

A biomimetic host from a poultry bone structure enables dendrite‐free lithium deposition

Carbon Energy, EarlyView.
A porous carbon material with cross‐linked nanostructures was prepared, drawing inspiration from the crosslinking trabeculae found in poultry bones. Due to the stable pore structure and abundant heteroatom sites, the deposition behavior of lithium metal was uniform, thus maintaining low nucleation overpotential and preventing dendrite formation ...
