The ageing holobiont: crosstalk between telomere dynamics, oxidative stress and the gut microbiome
Biological Reviews, EarlyView.ABSTRACT The gut tissue is at the frontline of early onset of ageing. It exhibits high cell turnover rates and rapid telomere shortening, which can have systemic effects on the developing or senescing organism. We conducted a literature review of studies on the crosstalk between telomere length dynamics, telomerase activity, oxidative stress, and gut ...

The extension of the taxon cycle model to island plants: insights from the Canarian vascular flora
Biological Reviews, EarlyView.ABSTRACT Taxon cycle models describe eco‐evolutionary patterns of lineage colonization, diversification, and decline across archipelagos, inferring an important role for competition amongst ecologically similar taxa in driving concurrent niche changes.

How wildlife respond to tropical cyclones: short‐term tactics and long‐term impacts
Biological Reviews, EarlyView.ABSTRACT From butterflies to lizards and from sharks to seabirds, wildlife exhibit tactics to survive the impacts of tropical cyclones, also known as hurricanes, cyclones, or typhoons depending on where they occur. Some species seek refuge during the storm by moving, some remain in place and ride it out, and others move longer distances, avoiding the ...

Loss, persistence and reversal of phenotypic traits
Biological Reviews, EarlyView.ABSTRACT The irreversibility of complex trait loss has long been a tenet of evolutionary biology. However, this idea is increasingly at odds with the numerous documented exceptions across the Tree of Life. We synthesise this growing body of evidence across a diverse array of taxa and traits, exploring the evolutionary conditions that enable ...
