Data from: The influence of topography and soil phosphorus on the vegetation of Korup Forest Reserve, Cameroun

Duncan W. Thomas, David M. Newbery, P. G. Waterman & J. S. Gartlan
All living trees (≥ 30 cm gbh) were enumerated in 135 80×80 m plots, each subdivided into four 40×40 m subplots, and arranged along four 5 km transect lines in the Korup Forest Reserve, Cameroun. For each plot altitude, slope and the extent of permanent and seasonal swamps were recorded. Four hundred and eleven taxa were recognized of which 66% were identified to species. Mean tree density was 471 ha−1, basal area 27.6 m2 ha−1...

Data from: Brassicales phylogeny inferred from 72 plastid genes: a reanalysis of the phylogenetic localization of two paleopolyploid events and origin of novel chemical defenses

PREMISE OF THE STUDY - Previous phylogenetic studies employing molecular markers have yielded various insights into the evolutionary history across Brassicales, but many relationships between families remain poorly supported or unresolved. A recent phylotranscriptomic approach utilizing 1155 nuclear markers obtained robust estimates for relationships among 14 of 17 families. Here we report a complete family‐level phylogeny estimated using the plastid genome. METHODS - We conducted phylogenetic analyses on a concatenated data set comprising 44,926 bp...

Data from: The ephemerality of secondary forests in southern Costa Rica

J. Leighton Reid, Matthew E. Fagan, James Lucas, Joshua Slaughter & Rakan A. Zahawi
Secondary forests are increasingly recognized for conserving biodiversity and mitigating global climate change, but these and other desired outcomes can only be achieved after decades of regeneration, and secondary forests are frequently recleared before they recover to predisturbance conditions. We used a time series of aerial photographs (1947-2014) to evaluate multidecadal persistence of secondary forests across a 320 sq. km landscape in southern Costa Rica. Secondary forests had relatively short lifespans, with 50% recleared within...

Data from: A latitudinal gradient in dimensionality of biodiversity

Richard D. Stevens & J. Sebastian Tello
Biodiversity is multifaceted and represents numerous dimensions expressing variation in richness and abundances of species, ecosystem functions, phylogenetic relationships, morphology, traits and interactions. Such dimensions are correlated to varying degrees and recent research has attempted to better understand behavior of such correlations. We define dimensionality of biodiversity as degree of redundancy in variation among multiple dimensions of biodiversity. One fundamental question regarding biodiversity is whether its dimensionality is spatially structured, also exhibiting geographic gradients. We...
