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: Shaping communicative colour signals over evolutionary time

Alison G. Ossip-Drahos, José R. Oyola Morales, Cuauhcihuatl Vital-Garcia, José Jaime Zúñiga-Vega, Diana K. Hews & Emilia P. Martins
Many evolutionary forces can shape the evolution of communicative signals, and the long-term impact of each force may depend on relative timing and magnitude. We use a phylogenetic analysis to infer the history of blue belly patches of Sceloporus lizards, and a detailed spectrophotometric analysis of four species to explore the specific forces shaping evolutionary change. We find that the ancestor of Sceloporus had blue patches. We then focus on four species; the first evolutionary...

Data from: Joint effects of habitat, zooplankton, host stage structure and diversity on amphibian chytrid

Jessica L. Hite, Jaime Bosch, Saioa Fernández-Beaskoetxea, Daniel Medina & Spencer R. Hall
Why does the severity of parasite infection differ dramatically across habitats? This question remains challenging to answer because multiple correlated pathways drive disease. Here, we examined habitat–disease links through direct effects on parasites and indirect effects on parasite predators (zooplankton), host diversity and key life stages of hosts. We used a case study of amphibian hosts and the chytrid fungus, Batrachochytrium dendrobatidis, in a set of permanent and ephemeral alpine ponds. A field experiment showed...
