TL;DR: The broad suite of measurements made at CTFS-ForestGEO sites makes it possible to investigate the complex ways in which global change is impacting forest dynamics, and continued monitoring will provide vital contributions to understanding worldwide forest diversity and dynamics in an era of global change.

Seed mass and mast seeding enhance dispersal by a neotropical scatter-hoarding rodent
TL;DR: It is concluded that scatter-hoarding rodents can select for both large seed crops and large seeds, which may reinforce mast seeding.

TL;DR: It is shown that most tree species are extremely rare, meaning that they may be under serious risk of extinction at current deforestation rates, and a methodological framework for estimating species richness in trees is provided that may help refine species richness estimates of tree-dependent taxa.
Journal ArticleDOI
Quantifying levels of animal activity using camera trap data
J. Marcus Rowcliffe,Roland Kays,Roland Kays,Bart Kranstauber,Bart Kranstauber,Chris Carbone,Patrick A. Jansen,Patrick A. Jansen +7 more
TL;DR: In this article, the authors present a method to estimate activity level with time-of-detection data from camera traps, fitting a flexible circular distribution to these data to describe the underlying activity schedule, and calculating overall proportion of time active from this.
Journal ArticleDOI
Thieving rodents as substitute dispersers of megafaunal seeds
Patrick A. Jansen,Patrick A. Jansen,Ben T. Hirsch,Ben T. Hirsch,Willem-Jan Emsens,Willem-Jan Emsens,Veronica Zamora-Gutierrez,Veronica Zamora-Gutierrez,Martin Wikelski,Roland Kays,Roland Kays +10 more
TL;DR: It is demonstrated that communities of rodents can in fact provide highly effective long-distance seed dispersal, suggesting that thieving scatter-hoarding rodents could substitute for extinct megafaunal seed dispersers of tropical large-seeded trees.
