MORPHOLOGICAL ADAPTATION  

Definition

  • Many animals show unique morphological and behavioural adaptations to desert extremes, while others are able to avoid these by behavioural means. This chapter focuses on patterns of convergent evolution of traits to assess which features represent unique desert adaptations. There are several taxa for which suitable, phylogenetically-controlled analyses have been conducted. This means that the effects of phylogeny, which may be considerable, have been removed. Removing the effects of phylogeny allow one to test whether an adaptation has occurred. For example, a character may be considered a desert adaptation because many desert-dwelling species possess the character, and non-desert-dwelling species do not. However, if there are many desert-dwelling species in a particular part of a clade, then this character may have evolved by chance alone. Select examples from tenebrionid beetles, lizards, birds, and mammals are considered. (en)
