The signalling cascades involved in many biological processes require the coordination of different subcellular districts. It is the case of the pathways involved in spermatozoa acquisition of fertilizing ability (the so called "capacitation"). In the present work the coordination of subcellular signalling, during the boar sperm capacitation, was studied by a computational and experimental approach. As first the biological network representing all the molecular interactions involved in capacitation was build and analyzed, then, an experimental set up was carried out to confirm the computational model-based prediction.
Raptors are some of the most at-risk groups of birds in the world and saving these top predators is essential for maintaining the health of many ecosystems. After hospitalization, raptors are often released when muscular recovery is still unfitting when they are unable to hunt efficiently and are at risk of dying from starvation within a few days. On the other hand, if a convalescent bird is trained with the only use of classic falconry techniques, it is likely to remain dependent on the caretaker/falconer even long after the release, so unable to hunt independently. To overcome these problems, a new training method was conceived, which could improve raptors’ muscular strength while limiting habituation to humans. This has been possible due to the combination of classic falconry techniques and modern technologies, such as the introduction of specific workouts with drones. Three falconry raptors and one wild Eurasian hobby were trained through high-tech falconry to develop the ability to catch, grasp, and airlift their prey at a different speed, altitude, and resistance. The main findings of this study were: (i) The rapid increase of the raptors’ speed; (ii) the muscular growth and endurance, and (iii) successful reintroduction of a wild bird.
The overpopulation of shelters and the increase of homeless dogs have become serious problems in many countries. One contributor to the number of both sheltered and homeless dogs is the abandonment and relinquishment of pet dogs by their owners for different reasons – in many cases depending on dogs’ undesirable or problematic behaviors. Luckily, the behavioral characteristics of a dog are, to some extent, modifiable parameters. The aim of this study was to train the dogs housed in a garden shelter in Italy to become suitable as pets by becoming familiar to different tools and situations that they could encounter in a domestic setting through a customized educational path based on social and environmental enrichment. Shelters can hardly afford the expenses for administering training to dogs. The problem could be overcome by engaging the best graduating students attending referenced training schools, whose mission is to train professionals with high theoretical and practical skills. Shelters’ administrators should choose referenced schools only, that teach positive training methods respectful of animals and that support the human–animal bond.
