Data from: Local neighbourhood and regional climatic contexts interact to explain tree performance

Jenny Zambrano, Philippe Marchand & Nathan G. Swenson
Tree neighbourhood modelling has significantly contributed to our understanding of the mechanisms structuring communities. Investigations into the impact of neighbouring crowding on tree performance have generally been conducted at local scales, missing important regional-scale context such as the suitability of the climate for each species. Favourable climates may enhance tree performance, but this may come at the cost of increased neighbourhood crowding and competition negatively impacting survival and growth. Through the synthesis of continental-scale forest...

Data from: Neighborhood defense gene similarity effects on tree performance: a community transcriptomic approach

Jenny Zambrano, Yoshiko Iida, Robert Howe, Luxiang Lin, Maria Natalia Umana, Amy Wolf, Samantha J. Worthy & Nathan G. Swenson
The structure and dynamics of ecological communities are ultimately the outcome of the differential demographic rates of individuals. Individual growth and mortality rates largely result from the interaction between an organism's phenotype and the abiotic and biotic environment. Functional traits have been used extensively over the past decade to elucidate links among phenotypes, demography and community dynamics. A fundamental weakness of most functional trait approaches is the use of ‘soft’ traits associated with resource acquisition...

Data from: Vegetation cover in relation to socioeconomic factors in a tropical city assessed from sub-meter resolution imagery

Sebastián Martinuzzi, Olga M. Ramos-González, Tischa A. Muñoz-Erickson, Dexter H. Locke, Ariel E. Lugo & Volker C. Radeloff
Fine-scale information about urban vegetation and social-ecological relationships is crucial to inform both urban planning and ecological research, and high spatial resolution imagery is a valuable tool for assessing urban areas. However, urban ecology and remote sensing have largely focused on cities in temperate zones. Our goal was to characterize urban vegetation cover with sub-meter resolution aerial imagery, and identify social-ecological relationships of urban vegetation patterns in a tropical city, the San Juan Metropolitan Area,...

Data from: Pre-dispersal seed predators and fungi differ in their effect on Luehea seemannii capsule development, seed germination and dormancy across two Panamanian forests

Pimonrat Tiansawat, Noelle G. Beckman & James W. Dalling
Pre-dispersal seed predation can greatly reduce crop size affecting recruitment success. Additionally, non-fatal damage by seed predators may allow infection by fungi responsible for post-dispersal seed losses. The objectives of this study were (1) to quantify pre-dispersal seed predation and fungal infection in a Neotropical tree species, Luehea seemannii, that produces dehiscent fruits and wind-dispersed seeds, and (2) to link pre-dispersal effects on seed quality to seed survival in the soil. To examine how seed...
