英文摘要	Desertification is a serious ecological problem leading to significant biodiversity loss, but how desertification drives shifts in life history and fitness of animals remains understudied. To clarify whether habitat desertification causes shifts in life history strategies, we compared ecological factors and reproductive traits of Phr ynocephalus przewalskii from three different desertification habitats - fixed dune, semi-fixed dune and mobile dune of a semi-arid region of Inner Mongolia, at the eastern edge of Hobq Desert, China. Our results showed a significant shift in the egg size-number trade-off of P. przewalskii in response to desertification, with lizards from the mobile dune habitat producing smaller clutches of larger eggs than lizards from the fixed and semi-fixed dune habitats. This life history shift is likely adaptive and driven by abiotic factors (temperature and precipitation) rather than biotic factors (food availability and lizard population density). Our study demonstrates that habitat desertification drives the shift in egg size-number trade-off in a lizard and highlights the importance of exploring the life history responses of animals to habitat desertification as well as to other traditionally well-studied factors like temperature, especially in the context of future global climate change.
