Resting Behaviour of Parrots Loriculus galgulus
Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2014 This study analysed the preferences of perch size and position in the aviary in a group of 6 lorikeets (Loriculus galgulus). We monitored the presence of the lorikeets in four different locations in the aviary – on the original perches, floor, wire mesh ...

Asymmetric Whisker‐Inspired Sensor Pairs for Enhanced Airflow Sensing on Drones
Advanced Intelligent Systems, EarlyView.This work incorporates asymmetric cross‐sections into a whisker‐inspired sensor pair to enhance airflow sensing. By comparing signals between two offset asymmetric whiskers, the system improves flow heading estimation and identifies the presence of fan‐generated wind during quadrotor flight.

The mechanism of labor in nonhuman primates: A look inside
The Anatomical Record, EarlyView.Abstract While in humans, the flexed position of the fetus and its rotating course down the birth canal are well documented, in other primates the mechanism of labor is unknown. Despite the lack of comparative data, it is commonly assumed that the human obstetric mechanism is unique, and anthropologists have disputed when and why the transition to the ...

Human evolution and the obstetrical dilemma: The pelvic floor hypothesis
The Anatomical Record, EarlyView.Abstract Human childbirth is mechanically difficult because a large‐headed, broad‐shouldered fetus must pass through a comparatively narrow, twisted bony birth canal. Traditional explanations of this “obstetrical dilemma” emphasize the role of bipedal locomotion in inhibiting the evolution of a wider, more spacious pelvis.

Biological Diversity, EarlyView.Mesozooplankton assemblages differed significantly both between and within Baltic Sea bays, driven mainly by local salinity and temperature gradients. Distinct communities occurred over distances of less than 1 km, demonstrating strong fine‐scale spatial variability.
