Survival rates of captive-bred Asian Houbara Chlamydotis macqueenii in a hunted migratory population [PDF]

open access: yes, 2016
Asian Houbara Chlamydotis macqueenii numbers are declining owing to unsustainable levels of hunting and poaching, with the main conservation response being population reinforcement through the release of captive-bred birds.

Atmospheric conditions create freeways, detours and tailbacks for migrating birds

open access: yesJournal of Comparative Physiology, 2017
The extraordinary adaptations of birds to contend with atmospheric conditions during their migratory flights have captivated ecologists for decades. During the 21st century technological advances have sparked a revival of research into the influence of ...

Brain‐Wide Spatiotemporally Distinct Traveling Waves Drive Anxiety‐Like Behaviors in Mice

open access: yesAdvanced Science, EarlyView.
J.Liu et al. reveal the complete propagation dynamics of cortical traveling waves, from local circuitry initiation to long‐range propagation, and identify their functional relevance in modulating anxiety‐like behaviors and underlying cellular neuroplasticity in mice.

Spread of HPAIV H5N1 from south china agro-ecosystems through wild birds migration: a multidisciplinary approach [PDF]

open access: yes, 2012
Agricultural intensification in South China has increased densities of domestic ducks raised on intensively irrigated paddy fields, an important factor of the persistence of H5N1 highly pathogenic avian influenza virus (AIV) persistence.

Environmental complexity: A buffer against stress in the domestic chick [PDF]

open access: yes, 2019
Birds kept in commercial production systems can be exposed to multiple stressors from early life and this alters the development of different morphological, immunological and behavioural indicators.

Experimental Infection of North American Birds with the New York 1999 Strain of West Nile Virus

open access: yesEmerging Infectious Diseases, 2003
To evaluate transmission dynamics, we exposed 25 bird species to West Nile virus (WNV) by infectious mosquito bite. We monitored viremia titers, clinical outcome, WNV shedding (cloacal and oral), seroconversion, virus persistence in organs, and ...

A MXene‐Based Nanothermal Knife Inhibits Aggresome‐Mediated Persister Formation for Preventing Dental Caries

open access: yesAdvanced Science, EarlyView.
Early childhood caries (ECC) involves cariogenic persisters that evade antimicrobial treatment. Persisters achieve this by downregulating heat shock proteins (HSPs) and formation of protein aggregates. Ti3C2 MXene‐based photothermal therapy (PTT) acts as a “nanothermal knife,” disrupting membranes, upregulating HSPs, inhibits aggregates, prevents ...

Current Knowledge of Helminths of Wild Birds in Ecuador

open access: yesBirds
Parasitic helminths are diverse in wild birds globally, but knowledge about helminths in Ecuadorian avifauna is still fragmentary. In the present review, records about helminths (Platyhelminthes, Nematoda, and Acanthocephala) in Ecuadorian wild birds is ...

Secondary Electron Hyperspectral Imaging of Carbons: New Insights and Good Practice Guide

open access: yesAdvanced Science, EarlyView.
Secondary hyperspectral imaging of carbon surfaces is assessed with reference materials and in comparison to standard spectroscopies. Characterization of functional carbon materials from battery research reveals otherwise inaccessible information about the distribution of sp2 and amorphous carbon, as shown in graphite anode and carbon coated lithium ...
