The practicality of practice: A model of the function of play behaviour

open access: yesEcology and Evolution, Volume 13, Issue 9, September 2023., 2023
It has been hypothesised that play offers practice for serious adult behaviour. By modelling the repeated choices between three behaviours: foraging, play and rest, we show that play may be optimal, because of potential safety benefits, even if it only offers an inferior form of practice for serious behaviour.

Population analysis of retrotransposons in giraffe genomes supports RTE decline and widespread LINE1 activity in Giraffidae

open access: yesMobile DNA, 2021
Background The majority of structural variation in genomes is caused by insertions of transposable elements (TEs). In mammalian genomes, the main TE fraction is made up of autonomous and non-autonomous non-LTR retrotransposons commonly known as LINEs and
