Data from: Altitudinal migration and the future of an iconic Hawaiian honeycreeper in response to climate change and management

Alban Guillaumet, Wendy A. Kuntz, Michael D. Samuel & Eben H. Paxton
Altitudinal movement by tropical birds to track seasonally variable resources can move them from protected areas to areas of increased vulnerability. In Hawaiʻi, historical reports suggest that many Hawaiian honeycreepers such as the ‘I'iwi (Drepanis coccinea) once undertook seasonal migrations, but the existence of such movements today is unclear. Because Hawaiian honeycreepers are highly susceptible to avian malaria, currently minimal in high-elevation forests, understanding the degree to which honeycreepers visit lower elevation forests may be...

Data from: A rich diversity of opercle bone shape among teleost fishes

Charles B. Kimmel, Clayton M. Small & Matthew L. Knope
The opercle is a prominent craniofacial bone supporting the gill cover in all bony fish and has been the subject of morphological, developmental, and genetic investigation. We surveyed the shapes of this bone among 110 families spanning the teleost tree and examined its pattern of occupancy in a principal component-based morphospace. Contrasting with expectations from the literature that suggest the local morphospace would be only sparsely occupied, we find primarily dense, broad filling of the...

Data from: Incipient ecological speciation between successional varieties of a dominant tree involves intrinsic postzygotic isolating barriers

Elizabeth A. Stacy, Bhama Paritosh, Melissa A. Johnson & Donald K. Price
Whereas disruptive selection imposed by heterogeneous environments can lead to the evolution of extrinsic isolating barriers between diverging populations, the evolution of intrinsic postzygotic barriers through divergent selection is less certain. Long-lived species such as trees may be especially slow to evolve intrinsic isolating barriers. We examined postpollination reproductive isolating barriers below the species boundary, in an ephemeral hybrid zone between two successional varieties of the landscape-dominant Hawaiian tree, Metrosideros polymorpha, on volcanically active Hawai'i...
