Data from: Community functional trait composition at the continental scale: the effects of non-ecological processes

A. Michelle Lawing, Jussi T. Eronen, Jessica L. Blois, Catherine H. Graham & P. David Polly
Ecological communities and their response to environmental gradients are increasingly being described by measures of trait composition at the community level – the trait-based approach. Whether ecological or non-ecological processes influence trait composition between communities has been debated. Understanding the processes that influence trait composition is important for reconstructing paleoenvironmental conditions from fossil deposits and for understanding changes in community functionality through time. Here, we assess the influence of ecological and non-ecological processes on the...

Data from: The future distribution of the savannah biome: model-based and biogeographic contingency

Glenn R. Moncrieff, Simon Scheiter, Liam Langan, Steven I. Higgins & Antonio Trabucco
The extent of the savanna biome is expected to be profoundly altered by climatic change and increasing atmospheric CO2 concentrations. Contrasting projections are given when using different modelling approaches to estimate future distributions. Furthermore, biogeographic variation within savannas in plant function and structure is expected to lead to divergent responses to global change. Hence the use of a single model with a single savanna tree type will likely lead to biased projections. Here we compare...

Data from: Unifying latitudinal gradients in range size and richness across marine and terrestrial systems

Adam Tomasovych, Jonathan D. Kennedy, Tristan J. Betzner, Nicole Bitler Kuehnle, Stewart Edie, Sora Kim, K. Supriya, Alexander E. White, Carsten Rahbek, Shan Huang, Trevor D. Price & David Jablonski
Many marine and terrestrial clades show similar latitudinal gradients in species richness, but opposite gradients in range size—on land, ranges are the smallest in the tropics, whereas in the sea, ranges are the largest in the tropics. Therefore, richness gradients in marine and terrestrial systems do not arise from a shared latitudinal arrangement of species range sizes. Comparing terrestrial birds and marine bivalves, we find that gradients in range size are concordant at the level...

Data from: Effects of hummingbird morphology on specialization in pollination networks vary with resource availability

Boris A. Tinoco, Catherine H. Graham, Juan M. Aguilar & Matthias Schleuning
Specialization of species in interaction networks influences network stability and ecosystem functioning. Spatial and temporal variation in resource availability may provide insight into how ecological factors, such as resource abundance, and evolutionary factors, such as phylogenetically conserved morphological traits, influence specialization within mutualistic networks. We used independent measures of hummingbird abundance and resources (nectar), information on hummingbird traits and plant–hummingbird interactions to examine how resource availability and species' morphology influence the specialization of hummingbirds in...
