Colour Polymorphism in Coconut Crabs Is Under Relaxed Selection From Conspecifics?

open access: yesEthology, EarlyView.
Coconut crabs are either red or blue irrespective of age or sex, are nocturnal and have very few predators. This experimental study shows that they do not use conspecific's colour but do use relative size to settle competitive interactions over food in the wild.

Directed evolution of the fusion enzyme for improving astaxanthin biosynthesis in Saccharomyces cerevisiae

open access: yesSynthetic and Systems Biotechnology, 2022
The accumulation of the intermediate zeaxanthin and canthaxanthin in the astaxanthin biosynthesis pathway catalyzed by β-carotene hydroxylase (crtZ) and β-carotene ketolase (crtW) decreases the content of the astaxanthin.

First attempt at using a synthetic diet in short‐lived killifish, a vertebrate model of ageing

open access: yesJournal of Fish Biology, EarlyView.
Abstract Diet standardization of model organisms is crucial for experimental consistency and repeatability in laboratory research, yet laboratory fish often lack species‐specific, open‐formula standardized diets. This study aims to address this gap by testing the effect of macronutrient content on the performance of Nothobranchius furzeri, an ...
