Morphological adaptations for relatively larger brains in hummingbird skulls
(2018)A common allometric pattern called Haller’s Rule states that small species have relatively larger brains and eyes than larger species of the same taxonomic group. This pattern imposes drastic structural changes and ... -
Morphological and ecological variation of a tropical anoline lizard: are agonistic interactions shaping ecomorphological relationships?
(2018)Ecologists have long been intrigued by which factors influence habitat use by an organism and how communities are structured. However, the links between habitat preferences, morphology, biotic interactions and community ... -
