Divergent defense strategies and niche partitioning in Cretaceous micro‐beetles

Journal of Systematics and Evolution, EarlyView.
We report a new clambid beetle from mid‐Cretaceous Kachin amber, Scutacalyptus kolibaci gen. et sp. nov., characterized by a flattened body and explanate margins. Alongside spiny and conglobating clambid forms, this diversity reflects niche partitioning and varied antipredator strategies in the Cretaceous forest floor.

Testing the size‐grain hypothesis in a generalist predator: The case of an ant species in the Brazilian savannah

Journal of Zoology, EarlyView.
In our recent study, we examined whether ants in the Brazilian Cerrado follow the “grain‐size hypothesis,” which proposes that larger ants should have proportionally longer legs to move efficiently across different environments. We used Ectatomma permagnum, a common predatory ant in the Cerrado, measuring hundreds of individuals collected from various ...

Postembryonic development of the predatory strike mechanics in a praying mantis (Insecta: Mantodea)

Physiological Entomology, EarlyView.
Praying mantis forelegs capture prey using specific kinematic and kinetic traits that change in size and morphology during postembryonic growth and sexual dimorphism influences these dynamics. Strike forces grow hyperallometrically with body weight; larger mantises show longer strike durations, slower joint angular velocities and increased tibia ...

Der posteriore tibiale slope – Vergleich und Evaluation verschiedener Messmethoden

Bei zunehmender Lebenserwartung, vermehrter körperlicher Aktivität sowie steigendem Anspruch der Bevölkerung an die moderne Medizin sind eine korrekte Achslage, gute postoperative Ergebnisse mit langfristigen Standzeiten sowie geringe Revisionsrisiken und stabile Kniegelenksprothesen wichtige Faktoren für die operative Versorgung von ...

Jumping on the moon as a potential exercise countermeasure

Experimental Physiology, EarlyView.
Abstract The Moon's gravitational field strength (17% Earth's gravity) may facilitate the use of bodyweight jumping as an exercise countermeasure against musculoskeletal and cardiovascular deconditioning in reduced gravity settings. The present study characterised the acute physiological and kinetic responses to bodyweight jumping in simulated Lunar ...

Isometric training at longer muscle–tendon complex lengths: A potential countermeasure to impaired neuro‐muscle–tendon function during space travel

Experimental Physiology, EarlyView.
Abstract Manned space exploration to distant destinations, including Mars, continues to be an aspiration of humankind. Space travel does, however, present many challenges to the body, amongst which adaptation to microgravity is perhaps the largest. For instance, both short and long manned spaceflight missions have shown substantial deleterious effects ...
