The "new diverted bed" of the Sperchios river and the new National Road Athina-Lamia in the area of the "Alamana Bridge" and the impact to the environment to the coastal area of the Maliakos Gulf and the Delta (Fthiotida-Greece)
The purpose of this work is to depict and evaluate the alterations in the geomorphological characteristics and the hydro-geomorphological processes as well as the effects to the environment of the coastal area of the Maliakos gulf and the delta of the Sperchios river, as a result of the construction of the "new bed" of the new diverted bed of Sperchios river, the "New Alamana Bridge" and the construction of the long embankments which are constructed in order to facilitate the road works for the New National Road Athina-Lamia in the section Thermopylae - Lamia (Fthiotida-Greece)
Works for the diversion of bed of rivers and torrents and their impact to the environmental of the Lagoons of Greece and Italy
This work deals with the comparative account and evaluation of the impact to the environment and especially with the alterations to the geomorphological structure and the hydro-geomorphological processes caused by the works for the diversion of the beds and the flow of rivers and torrents in the greater area of the "Katafourko lagoon" in Greece and of the "Venice lagoon" in Italy. Human intervention in the study areas, was of different aims in each location, but it all resulted in the alteration of the dynamic evolution of the hydro-geomorphological processes which has led to the creation of an "artificial" environment, controlled to a great extend by human power and which in turn, in the long term re-strengthens and reenforces the possibility of environmental destabilization

Brown bear attacks on humans : a worldwide perspective
The increasing trend of large carnivore attacks on humans not only raises human safety concerns but may also undermine large carnivore conservation efforts. Although rare, attacks by brown bears Ursus arctos are also on the rise and, although several studies have addressed this issue at local scales, information is lacking on a worldwide scale. Here, we investigated brown bear attacks (n = 664) on humans between 2000 and 2015 across most of the range inhabited by the species: North America (n = 183), Europe (n = 291), and East (n = 190). When the attacks occurred, half of the people were engaged in leisure activities and the main scenario was an encounter with a female with cubs. Attacks have increased significantly over time and were more frequent at high bear and low human population densities. There was no significant difference in the number of attacks between continents or between countries with different hunting practices. Understanding global patterns of bear attacks can help reduce dangerous encounters and, consequently, is crucial for informing wildlife managers and the public about appropriate measures to reduce this kind of conflicts in bear country.Peer reviewe

Human interventions and alterations of the geomorphological characteristics in parts of the coastal area in the Ionian coasts (Ipiros-Greece)
According to data results from in situ observations and the interpretation of aerial photography of the past, it arises that in general therms the state of the coasts in the study area is fragile, while there is a predominant tendency of regression of the coast line towards the inland
