TL;DR: A workflow and associated software for performing calibration of cameras placed in a field setting and estimating the accuracy of the resulting stereoscopic reconstructions that other researchers may use to calibrate their own cameras.

TL;DR: The kinematics of explosive dispersal and self-burial based on detailed high-speed and time-lapse videos are described and a simple mechanical model that accounts for the coiling behavior of the awn is developed to examine tradeoffs between dispersal distance and reliability of the dispersal mechanism.

TL;DR: Argus is a free and open source toolset for using consumer grade cameras to acquire 3D kinematic data in field settings and will open up new areas of biological study by providing precise 3D tracking and quantification of animal and human movement to researchers in a wide variety of field and laboratory contexts.

TL;DR: It is found that the swift flock is structured around local rules based on physical distance, that subgroup size increases with density, and that there exist regions of the flock that are less cooperative than others, in particular the chimney entry zone.

TL;DR: Interspecific differences in anchor-ice formation and propagation characteristics for Antarctic benthic organisms show increased incidence of formation and accelerated spread of ice crystals compared to urchins and sea stars, and are consistent with, and provide a potential first step toward, an explanation for disturbance patterns observed in shallow polar benthics communities.
