Digital 3D models and measurements of avian brain cavity, blood vessel and nerve endocasts

S. A. Walsh, A. N. Iwaniuk, M. A. Knoll, E. Bourdon, P. M. Barrett, A. Milner, R. Nudds, R. L. Abel & P. Dello Sterpaio
This dataset comprises cast reconstructions of brain cavity space in 60 extant avian species, derived from X-ray micro computed-tomography scan image stacks. Each reconstruction was made using Materialise Mimics 14.11 to create volumetric models (brain cavity casts) that were then transformed into the polygon mesh stereolithograph (STL) files archived here. Brain cavity cast models are in most cases accompanied by casts of main vascular features (e.g., carotid arteries) and the olfactory nerves (CN I). A...

Data from: Recombinant DNA modification of gibberellin metabolism alters growth rate and biomass allocation in Populus

Overexpression of genes that modify gibberellin (GA) metabolism and signaling have been previously shown to produce trees with improved biomass production but highly disturbed development. To examine if more subtle types of genetic modification of GA could improve growth rate and modify tree architecture, we transformed a model poplar genotype (Populus tremula × P. alba) with eight genes, including two cisgenes (intact copies of native genes), four intragenes (modified copies of native genes), and two...

Data from: Fitness declines toward range limits and local adaptation to climate affect dispersal evolution during climate-induced range shifts

Anna L. Hargreaves, Susan F. Bailey & Robert A. Laird
Dispersal ability will largely determine whether species track their climatic niches during climate change, a process especially important for populations at contracting (low-latitude/low-elevation) range limits that otherwise risk extinction. We investigate whether dispersal evolution at contracting range limits is facilitated by two processes that potentially enable edge populations to experience and adjust to the effects of climate deterioration before they cause extinction: (i) climate-induced fitness declines towards range limits and (ii) local adaptation to a...

Data from: Gene flow of a forest-dependent bird across a fragmented landscape

Rachael V. Adams & Theresa M. Burg
Habitat loss and fragmentation can affect the persistence of populations by reducing connectivity and restricting the ability of individuals to disperse across landscapes. Dispersal corridors promote population connectivity and therefore play important roles in maintaining gene flow in natural populations inhabiting fragmented landscapes. In the prairies, forests are restricted to riparian areas along river systems which act as important dispersal corridors for forest dependent species across large expanses of unsuitable grassland habitat. However, natural and...
