Coping with compliance during take-off and landing in the diamond dove (Geopelia cuneata). [PDF]
PLoS ONE, 2018 The natural world is filled with substrates of varying properties that challenge locomotor abilities. Birds appear to transition smoothly from aerial to terrestrial environments during take-offs and landings using substrates that are incredibly variable.

Smart Bioinspired Material‐Based Actuators: Current Challenges and Prospects
Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.This work gathers, in a review style, an extensive and comprehensive literature overview on the development of autonomous actuators based on synthetic materials, bringing together valuable knowledge from several studies. Furthermore, the article identifies the fundamental principles of actuation mechanisms and defines key parameters to address the size

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 ...

Effect of perches on morphology, welfare and behaviour of captive reared pheasants
Italian Journal of Animal Science, 2017 This study investigated the effect of providing elevated perches in growing pens on the morphology and behaviour of young pheasants. Pheasants reared with perches from one week old were observed roosting off the ground significantly more frequently when ...

Molecular investigations of outbreaks of Perch perhabdovirus infections in pike-perch
Diseases of Aquatic Organisms, 2017 In 2016, a total of 5 massive mortality episodes each affecting hundreds of thousands of pike-perch Sander lucioperca larvae occurred at 2 sites in 2 Western European countries. For each episode, perhabdoviruses related to the perch rhabdovirus (PRV) were detected in samples, using either PCR or cell culture combined with PCR.

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.
