Riparian reserves protect butterfly communities in selectively logged tropical forest
Abstract: Selective logging is the most widespread habitat disturbance in tropical forests. Primary forest set‐asides along riparian zones are mandated in many countries and a key question is whether these riparian reserves...

Phenotypic divergence between closely related species has long interested biologists. Taxa that inhabit a range of environments and have diverse natural histories can help understand how selection drives phenotypic divergence....
G-Quadruplexes
Guanine (G)-rich sequences in nucleic acids can assemble into G-quadruplex structures that involve G-quartets linked by loop nucleotides. The structural and topological diversity of G-quadruplexes have attracted great attention...
Synthesis of Novel Regenerable 13X Zeolite-Polyimide Adsorbent Foams
A new generic synthesis method is presented for the production of a polyimide (PI)/adsorbent (80 wt% 13X zeolite) regenerable foam filter. The method uses a dual parallel reaction foaming process comprising CO 2...

Remote stereocontrol in [3,3]-sigmatropic rearrangements
The Ireland - Claisen [3,3]-sigmatropic rearrangement has been used to access biologically important β,β′-dihydroxy α-amino acids. The rearrangement reported is highly stereoselective and offers excellent levels of remote...
RNA promotes phase separation of glycolysis enzymes into yeast G bodies in hypoxia.

Apr 17, 2020
In hypoxic stress conditions, glycolysis enzymes assemble into singular cytoplasmic granules called glycolytic (G) bodies. G body formation in yeast correlates with increased glucose consumption and cell survival. However, the...
Modelling and simulation of biased agonism dynamics at a G protein-coupled receptor.
Theoretical models of G protein-coupled receptor (GPCR) concentration-response relationships often assume an agonist producing a single functional response via a single active state of the receptor. These models have largely...

In many animals, mate choice is important for the maintenance of reproductive isolation between species. Traits important for mate choice and behavioral isolation are predicted to be under strong stabilizing selection within...
Repeated genetic adaptation to altitude in two tropical butterflies.
Evolutionary and ecological processes influencing chemical defense variation in an aposematic and mimetic Heliconius butterfly.
Anniina LK Mattila, Chris D Jiggins, Øystein H Opedal, Gabriela Montejo-Kovacevich, Érika C Pinheiro de Castro, W Owen McMillan, Caroline Bacquet, Marjo Saastamoinen
Jul 26, 2021
Chemical defences against predators underlie the evolution of aposematic coloration and mimicry, which are classic examples of adaptive evolution. Surprisingly little is known about the roles of ecological and evolutionary...
