Life history and mating systems select for male biased parasitism mediated through natural selection and ecological feedbacks [PDF]

open access: yes, 2010
Males are often the "sicker" sex with male biased parasitism found in a taxonomically diverse range of species. There is considerable interest in the processes that could underlie the evolution of sex-biased parasitism.

Cis‐unsaturated sphingolipids support growth of sphingoid base‐deficient yeast but impair plasma membrane integrity

open access: yesFEBS Open Bio, EarlyView.
Sphingoid base structures, the sphingolipid backbones, vary among species. We established yeast cells in which the native sphingoid base was replaced with plant‐type bases containing cis or trans double bonds. This is, to our knowledge, the first eukaryotic model mostly composed of sphingolipids containing cis‐unsaturated sphingoid base, providing a ...

The impact of a volcanic ash fall event on the Critically Endangered Barbados leaf-toed gecko Phyllodactylus pulcher

open access: yesOryx
Ecosystem disturbance is known to negatively affect herpetofauna. There are, however, few studies on the impact of volcanic ash fallout on reptile species and no known publications on any impacts on the family Phyllodactylidae.

Microbial profile of the appendix niche in acute appendicitis: a novel sampling approach

open access: yesFEBS Open Bio, EarlyView.
This study utilized a novel sampling method, ERAT (i.e. endoscopic retrograde appendicitis treatment)‐guided lumen aspiration, to obtain samples from the appendix, and shotgun metagenomic sequencing was performed for in situ characterization of the appendix microbiome in patients with acute appendicitis.

The Flora of Ceylon [PDF]

open access: yesNature, 1894
WHEN Dr. Trimen left England at the beginning of 1877 to undertake the directorate of the Ceylon Gardens, he had already formed the determination to elaborate the flora of Ceylon, and to publish a descriptive handbook of its botany. Those who knew him knew that this work would only be undertaken after due preparation and without undue haste, but that ...

Structural and functional characterization of chitinase from carnivorous plant Drosera adelae

open access: yesFEBS Open Bio, EarlyView.
A class I chitinase from the carnivorous plant Drosera adelae was expressed and purified using a yeast system, revealing high enzymatic activity. Structural analyses of the catalytic and chitin‐binding domains identified key tyrosine residues involved in substrate binding, offering insights into the enzyme's adaptation for insect digestion.
