An orphan dermaseptin from frog skin reversibly assembles to amyloid-like aggregates in a pH-dependent fashion.

15 Sep 2009 Dermaseptin PD-3-7 (aDrs) from frog skin contains three aspartic acid residues resulting in a negative net charge at neutral pH, as opposed to numerous other dermaseptins which are cationic helical antimicrobial peptides. Still, this peptide can be ... Read more...

Phylogenetic endemism: a new approach for identifying geographical concentrations of evolutionary history.

13 Sep 2009 We present a new, broadly applicable measure of the spatial restriction of phylogenetic diversity, termed phylogenetic endemism (PE). PE combines the widely used phylogenetic diversity and weighted endemism measures to identify areas where ... Read more...

Nutritional endoderm: a way to breach the holoblastic-meroblastic barrier in tetrapods.

13 Sep 2009 The deceptively simple evolutionary transition from complete, holoblastic cleavage of the zygote to incomplete, meroblastic cleavage occurred only once in tetrapods, with the evolution of the amniote egg. By examining the development of a frog with ... Read more...
