Tracing the evolutionary pathway: on the origin of mitochondria and eukaryogenesis

open access: yesThe FEBS Journal, EarlyView.
This study examines the stepwise transition from archaeal–bacterial associations to the emergence of eukaryotic cells. Metabolic cooperation and endosymbiosis fostered ecological and genetic integration, with extensive gene transfer reshaping host biology.

The development of insect diversity and ecosystem complexity on green roofs: A review

open access: yesInsect Conservation and Diversity, EarlyView.
A classification system of different roof types is presented to improve consistency in green roof research. Landscape and green roof characteristics influence ecosystem development, but can be further explained by ecological concepts, like neutral and niche theory.

Effects of elevation and microclimatic temperatures on butterfly–flower interaction networks in a Mediterranean mountain range

open access: yesInsect Conservation and Diversity, EarlyView.
We tested how elevation and microclimate influenced butterfly–flower interaction networks at the hottest time of year in a Mediterranean mountain range. Interactions were dominated at all sites by one or two abundant butterfly and flower species, but butterfly networks were more robust to plant species loss at higher elevations. Nectar availability may

Anti‐melanogenic effects of Medicago sativa seed extracts on melanocytes

open access: yesInternational Journal of Cosmetic Science, EarlyView.
Our study demonstrated that two types of alfalfa seed extract: alfalfa ethanol precipitate (AEP) and alfalfa ethanol supernatant (AES) inhibited melanogenesis through the downregulation of tyrosinase expression, following the inactivation of CREB, b‐catenin and ERK signalling pathway in α‐melanocyte‐stimulating hormone (α‐MSH)‐stimulated B16F10 mouse ...
