Clarifying the demographic state of humankind during all periods of its historical development is an issue that has long been of interest to the scientific community. This paper traces the specifics and trends in the dynamics of the main demographic processes and structures of the population that has inhabited the Bulgarian lands in prehistory and antiquity. Their analysis allows us to establish that, according to the parameters of the studied indicators, the studied area can be related to the Mediterranean area, whose development was ahead of the rest of the world at that time.

In 2018, 23.2 Mt of pears were produced in the world across 1.3 million hectares (ha) of cultivated land. This review analyzes different training systems and management styles that have been adopted worldwide, emphasizing the European pear’s economic and environmental sustainability for the Mediterranean area of cultivation. Despite a reduced number of cultivars utilized around the world, pear presents a plethora of innovative training systems. In Europe, dwarfing rootstocks have led to reduced planting distances and a subsequent increase in planting density. Still, the economic sustainability of these systems is now questionable. Many of the quince rootstocks have made it possible to considerably reduce the size of the tree and introduce the concept of continuous row planting, with the management of orchards from the ground (i.e., pedestrian orchard). The planting distance must be chosen according to the soil fertility, the vigor of the grafting combination, and the training system. The planting distance dramatically affects the pruning and the management of soil, fertilization, and irrigation. The reduction of tree size also lowers the volume of spray necessary when applying pesticides. The variability in yield worldwide results from the interaction amongst cultivar/rootstock/training system/climate/management.

Migration and revolution in the Mediterranean area are inextricably connected. In this paper, I bring the stories of young Tunisian and Syrian revolutionaries of the 2008 and 2011 uprisings who were later forced into displacement and migration and who—both in their countries of origin and at European borders—demand freedom from their regimes’ oppression and freedom of movement. As European youth can mostly move freely in the world, Arab youth share the dream of doing the same. Both local tyrannies and their international allies, as well as unjust socioeconomic and migration policies, prevent these young people from living in dignity, from choosing where they live, and from being actors of change. The letters they share and the movement they found address an international audience and it to listen to their demands.

The genus Linum Linnaeus (1753: 277) consists of about 200 species distributed in temperate and tropical regions of the world. The Mediterranean area can be considered one of the centers of diversity of this genus (Greuter et al. 1989, Yilmaz et al. 2003, Yilmaz & Kaynak 2008, 2010, Tugay et al. 2010, Peruzzi 2011, Ruiz-Martin et al. 2015).

Pine forests of the Mediterranean area are subject to very serious depredations by the caterpillar of the Pine Processionary Moth. Although there are suitable habitats in other parts of the world, the moth has so far remained within this region because of its poor power of dispersal. Traditional methods of containing it are unsatisfactory and better results are to be expected from measures designed to stabilise the population at an acceptable level rather than to eradicate it entirely.

Silene Linnaeus (1753: 416) (Caryophyllaceae Juss.) is one of the largest genera of flowering plants in the world, consisting of about 700 species (Melzheimer 1988, Morton 2005) the majority of which are distributed in the Mediterranean area (Greuter 1995). The genus is critical from both taxonomic and nomenclatural points of views (see e.g., Petri et al. 2011, Rautenberg et al. 2011, Naciri et al. 2017, Đurović et al. 2018, Iamonico 2018).

We have been screening olive (Olea europea L.) cultivars using the Random Amplified Polymorphic DNA (RAPD) technique. We examined 23 olive cultivars selected to represent the important olive-growing regions of the world. These include oil and table olive cultivars originating from throughout the Mediterranean area. A high degree of polymorphisms is evident in the olive germplasm we examined. Early results indicate that polymorphisms that exist within the species are sufficient to enable efficient development of RAPD markers for distinguishing olive cultivars.

Species of the genus Lythrum Linnaeus (1753: 446) (Lythraceae) occur in temporary pools and wetlands (Morris, 2007) with about 35 species around the world (Graham, 2007). In the Mediterranean area, there are more than 10 species that mostly occur in temporary pools (Castroviejo Bolibar et al., 1997; Tison et al. 2014). Most of the species are also present in East and Central Asia (Webb, 1968). However, some species are limited to Europe, mostly Western Europe, e.g. L. flexuosum Lagasca (1816: 16) and L. baeticum González-Albo (1936: 141) (Castroviejo Bolibar et al., 1997), some are limited to West Asia, e.g. L. silenoides Boissier & Noë (in Boissier 1856: 55) (Ghazanfar, 2016), while Lythrum salicaria Linnaeus (1753: 446), the loosestrife, is widely distributed in Asia, Europe, Africa, Oceania and introduced in North America.

AbstractThe pillaging of archaeological sites throughout the world for salable items is increasing at an alarming rate. Recent information on looting in Mesoamerica, North America, and the Mediterranean area is summarized, and the weaknesses of the UNESCO and U.S.-Mexico treaties are outlined. Also described is a new and extremely destructive form of looting in Mesoamerica. It involves amassing many thousands of dollars from private investors for a project to decimate a chosen site, using explosives and power equipment, and then subdividing the loot among the sponsors. It is time for the SAA to act to stop the wanton destruction of the prehistoric record.

The paper analyses the data on ship and passenger availability in the busiest ports in the Republic of Croatia. In order to evaluate the variables related to cruiser traffic in seaports in the period from 2015 to 2023 in the Republic of Croatia, it was first necessary to determine the following most important variables of the proposed model: the port of Dubrovnik, the port of Split, the port of Zadar, the port of Rijeka and the port of Šibenik. The trends in passenger traffic from 2015 to 2023 for the five most important cruise ports in the Republic of Croatia were investigated. The values of the selected model variables were quantified on an index scale from zero to 100. This form of tourism is becoming more and more present on the international tourist market, offering numerous favourable opportunities, especially in the Mediterranean area. Due to its geo-traffic position, mild climate and rugged coastline, the Republic of Croatia is one of the most desirable cruising destinations in the world. The aim of this paper is to investigate and evaluate the cruise traffic variables of the busiest ports in the Republic of Croatia and to compare the observed ports with the port of Barcelona, as one of the most important ports for cruise ships in the Mediterranean. The conducted research indicates the constant growth of this form of tourism in the Republic of Croatia with the obligation to implement well-thought-out policies and strategies in order to achieve long-term sustainability.
