Color Polymorphism of Unfeathered Parts of the Great White Egret Ardea alba alba in Europe: An Analysis of the Internet Images

open access: yesDiversity, 2023
Polymorphism has been described in many avian taxa including Ardeidae. This study investigated the spatio-temporal distribution of color polymorphic forms (with regard to the color of the unfeathered parts (legs/lores)) of the Great White Egret Ardea ...

Impact of Intended Isocaloric Early versus Late Time‐Restricted Eating on Plasma Lipidome in Women with Overweight or Obesity: Secondary Analysis of the ChronoFast Trial

open access: yesAdvanced Science, EarlyView.
Women with overweight or obesity follow intended isocaloric early and late time‐restricted eating (TRE) in a crossover trial. Shotgun plasma lipidomics reveals no significant differences between interventions, but identify pronounced lipid changes—including reductions in ceramides and phosphatidylcholines—within the early TRE.

Re-classification of Clavibacter michiganensis subspecies on the basis of whole-genome and multi-locus sequence analyses

open access: yesInternational Journal of Systematic and Evolutionary Microbiology, 2017
Although the genus Clavibacter was originally proposed to accommodate all phytopathogenic coryneform bacteria containing B2γ diaminobutyrate in the peptidoglycan, reclassification of all but one species into other genera has resulted in the current ...

Molecular identification of different trypanosome species and subspecies in tsetse flies of northern Nigeria [PDF]

open access: yes, 2016
Background: Animal African Trypanosomiasis (AAT) is caused by several species of trypanosomes including Trypanosoma congolense, T. vivax, T. godfreyi, T. simiae and T. brucei. Two of the subspecies of T. brucei also cause Human African Trypanosomiasis.

Boosting Electrochemical Capacitive of Ultrathin Shower‐Pouf Birnessite‐Type MnO2 for Porous High‐Mass‐Loading Energy Storage Device

open access: yesAdvanced Science, EarlyView.
Ultrathin Shower‐pouf Birnessite‐type MnO2 (thickness: ~3 nm) has been fabricated via the specific adsorption of fluoride ions on the (001) crystal plane of birnessite. By constructing an electrically conductive network and optimizing electrode slurry concentration, the electrode mass loading can be substantially improved. These electrodes also exhibit

Selection maintains floral color polymorphism in scarlet paintbrush, Castilleja coccinea, reflecting combined ecological factors

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Evolutionary theory predicts polymorphism should be rare; however, intraspecific variation in floral color is common and can be attributed to genetic drift, plasticity, or variable selection. Examining floral color polymorphism both within contact zones and across a species' range can reveal the mechanisms maintaining this variation ...

Non-Invasive Genotyping of Honey Bee Queens Apis mellifera L.: Transition of the DraI mtDNA COI-COII Test to In Silico

open access: yesInsects, 2020
The honey bee Apis mellifera L. colony is headed by a single and indispensable queen, whose duty it is to ensure brood production and provide pheromonal stability within the colony. This study presents a non-invasive method that allows the identification
