Multi-species atlas resolves an axolotl limb development and regeneration paradox

Can Aztekin, Jixing Zhong, Georgios Tsissios, Evangelia Skoufa

Humans and other tetrapods are considered to require apical-ectodermal-ridge (AER) cells for limb development, and AER-like cells are suggested to be re-formed to initiate limb regeneration. Paradoxically, the presence of AER in the axolotl, a primary mode ...

Neuromechanical Simulations of Animats with Decentralised Control

Jonathan Patrick Arreguit O'Neill

The transition from aquatic to terrestrial environments represents a significant event in the history of evolution. For this transition to occur, animals had to adapt their morphology, physiology and locomotory skills to handle the challenges and interacti ...

Mechanisms Underlying the Recruitment of Inhibitory Interneurons in Fictive Swimming in Developing Xenopus laevis Tadpoles

Andrea Ferrario, Haoyu Zhang

Developing spinal circuits generate patterned motor outputs while many neurons with high membrane resistances are still maturing. In the spinal cord of hatchling frog tadpoles of unknown sex, we found that the firing reliability in swimming of inhibitory i ...

To regenerate or not to regenerate: Vertebrate model organisms of regeneration-competency and -incompetency

Can Aztekin

Why only certain species can regenerate their appendages (e.g. tails and limbs) remains one of the biggest mysteries of nature. Unlike anuran tadpoles and salamanders, humans and other mammals cannot regenerate their limbs, but can only regrow lost digit t ...

Automated flow control of a multi-lane swimming chamber for small fishes indicates species-specific sensitivity to experimental protocols

In fishes, swimming performance is considered an important metric to measure fitness, dispersal and migratory abilities. The swimming performance of individual larval fishes is often integrated into models to make inferences on how environmental parameters ...

PDMS filter structures for size-dependent larval sorting and on-chip egg extraction of C. elegans

Martinus Gijs, Furkan Ayhan, Hüseyin Baris Atakan

C. elegans-based assays require age-synchronized populations prior to experimentation to achieve standardized sets of worm populations, due to which age-induced heterogeneous phenotyping effects can be avoided. There have been several approaches to synchro ...

A meta-analysis reveals temperature, dose, life stage, and taxonomy influence host susceptibility to a fungal parasite

Suzanne Marie Young

Complex ecological relationships, such as host-parasite interactions, are often modeled with laboratory experiments. However, some experimental laboratory conditions, such as temperature or infection dose, are regularly chosen based on convenience or conve ...

Variable-stiffness tensegrity spine

Dario Floreano, Davide Zappetti, Enrico Ajanic, Roc Arandes Vilagrasa

Vertebrates, including amphibians, reptiles, birds, and mammals, with their ability to change the stiffness of the spine to increase load-bearing capability or flexibility, have inspired roboticists to develop artificial variable-stiffness spines. However, ...

Adaptive Compliant Foot Design for Salamander Robots

Auke Ijspeert, Kamilo Andres Melo Becerra, Robin Thandiackal, Laura Isabel Paez Coy

Aquatic stepping gaits in animals arguably display higher speed performance as well as energetic efficiency compared to other gaits using the limbs (i.e walking). This suggest that the foot structure and function contributes at a great extent on the propul ...

Indication of spatially random occurrence of Chlamydia-like organisms in Bufo bufo tadpoles from ponds located in the Geneva metropolitan area

Stéphane Joost, Oliver Michele Selmoni, Séverine Vuilleumier Varisco, Elia Vajana, Ivo Widmer

Occurrence of bacteria belonging to the order Chlamydiales was investigated for the first time in common toad (Bufo bufo) tadpole populations collected from 41 ponds in the Geneva metropolitan area, Switzerland. A Chlamydiales-specific real-time PCR was us ...
