Speciation in little: The role of range and body size in the diversification of Malagasy mantellid frogs (2011)
Journal Article
Wollenberg, K. C., Vieites, D. R., Glaw, F., & Vences, M. (2011). Speciation in little: The role of range and body size in the diversification of Malagasy mantellid frogs. BMC evolutionary biology, 11(1), Article 217. https://doi.org/10.1186/1471-2148-11-217

Background: The rate and mode of lineage diversification might be shaped by clade-specific traits. In Madagascar, many groups of organisms are characterized by tiny distribution ranges and small body sizes, and this high degree of microendemism and m...

It has been repeatedly suggested that mammalian cranial sutures act not only to allow growth but also to reduce the levels of strain experienced by the skull during feeding. However, because of the added complexity they introduce, sutures are rarely...

Male‐killing bacteria are thought to persist in host populations by vertical transmission and conferring direct and/or indirect fitness benefits to their hosts. Here, we test the role of indirect fitness benefits accrued from resource reallocation in...
