Researchers of the Hungarian Research Network (HUN-REN), the University of Debrecen (UD), the Eötvös Loránd University (ELTE) and the Hortobágy National Park Directorate investigated the social system of a herd of Przewalski's horses in Hortobágy by combining drone-based movement analysis and long-term population monitoring data.
, just like humans, live in a complex, multilevel society, the structure of which—and even group changes in the past and future—can be understood with the help of high-resolution aerial videos. The paper presenting the research was published in the journalInvestigating the social behavior of a large group of animals is time-consuming work if one uses classical observation methods.
"We took aerial videos of the herd using drones while they were moving around the reserve, and based on the footage, we determined the movement routes of all the individuals of the herd with high spatio-temporal resolution."The multilevel social structure that is also characteristic of humans is rare in animals.
The researchers combined the short-term movement observations of a few minutes with the long-term population monitoring data of the national park going back two decades. Since the establishment of the reserve, the wild horses have been individually recognized by the park staff who regularly collected data on population changes.
Between the closer harems, at the same time, the dispersal of mares was greater, which also contributes to the relations between harems through familiarity.

Researchers define protocol for high-resolution imaging of living cells using atomic force microscopyImages of nanoscale structures inside living cells are in increasing demand for the insights into cellular structure and function that they can reveal. So far, the tools for capturing such images have been limited, but researchers led by Takeshi Fukuma and Takehiko Ichikawa at Kanazawa University have now devised and reported a full protocol for using atomic force microscopy (AFM) to image inside living cells. The research is published in the journal STAR Protocols.
