Genetic Analysis of the Brown Bear Sub-Population in the Pindos Mountain, Central Greece: Insights into Population Status and Conservation.

Habitat fragmentation poses a significant threat to the existence and reproduction of large carnivores, such as brown bears, as it affects the genetic connectivity of populations and, consequently, their long-term viability. Understanding the genetic makeup and dispersal patterns in areas where brown bears live is crucial for developing effective conservation plans and promoting human-brown bear coexistence. In this study, 214 hair samples were collected non-invasively from brown bears and were genetically analyzed using fifteen specific microsatellite loci to shed light on the genetic status and demography of a sub-population residing in Central Greece (Trikala-Meteora area).

Introducing New Paths towards Public Primary Healthcare Services in Greece: Efforts for Scaling-Up Mental Healthcare Services Addressed to Older Adults.

The exponential growth in the aging population challenges the Primary Care Providers (PCPs) who provide health care services to older adults who are considered highly vulnerable and are in need of specialized healthcare services. The development of new policies and the adoption of appropriate health strategies by PCPs may improve the early detection and prevention of mental disorders in older adults. This reduces both queuing and costs in outpatient clinics while preventing stigma for patients and families.
