A "crown of thorns" is an inducible defense that protects Daphnia against an ancient predator.

Proceedings of the National Academy of Sciences of the United States of America - 17 Feb 2009

Abstract excerpt

Genetic data has become an essential part of ecological studies, because the analyses of diversity within and among natural populations may grant access to previously overlooked ecological and evolutionary causalities, especially among cryptic species. Here, we present an example of how phylogenetic analysis of molecular data obtained within a DNA barcoding study, in combination with morphological and ecological...
