    Mediterranean European rice fields provide important habitats for migrating waterbirds. In winter. one waterbird species that particularly benefits from rice fields is the Northern Lapwing (VaneIlus vanellas), a species threatened in Europe. To assess the effect of agii-environmental measures on rice field selection and use by wintering lapwings, bird counts were conducted in northeastern Spain during two consecutive winters (2005-2006 and 2006-2007). Information on two mandatory post-harvest management prescriptions of the agri-environment schemes was collected, namely winter flooding (percent ground surface covered by water) and whether fields were rolled or not. The number of lapwings in rolled fields was significantly higher compared to non-rolled fields. For instance. an average rolled field with 50% water cover (percentage at which lapwing abundance more or less peaked) would host an estimated 12.03 +/- 0.52 SE lapwings versus 0.18 +/- 0.58 in a non-rolled field. While the maximum abundance of lapwings in rolled fields was found at an intermediate percentage of water cover (about 25 to 75%), the number of lapwings increased steadily with water cover in non-rolled fields. Rice post-harvest practices derived from the agri-environment schemes are beneficial for biodiversity, promoting the conservation of suitable habitats for waterbirds.

    The concept of generic diversity expresses the 'diversification' of species into genera in a community. Since niche overlap is assumed to be higher in congeneric species, competition should increase generic diversity. On the other hand, generic diversity might be lower in highly selective environments, where only species with similar adaptations can survive. We used the distribution of tenebrionid beetles in Central Italy to investigate how generic diversity varies with elevation from sea level to 2400 m altitude. Generic diversity of geophilous tenebrionids decreased sharply with elevation, whereas the generic diversity of xylophilous tenebrionids showed similarly high values across the gradient. These results suggest that geophilous species are more sensitive to variation in environmental factors, and that the advantages of close relationships (similar adaptations to harsh conditions) are greater than the possible drawbacks (competition). This is consistent with the fact that geophilous tenebrionids are mostly generalist detritivores, and hence weakly affected by competition for resources. By contrast, xylophilous species are more protected from harsh/selective conditions, but more limited by competition for microhabitats and food. Our results support the environmental filtering hypothesis for the species composition of tenebrionid beetles along an elevational gradient.

    Rethinking Borders
    When governments have to decide what to do about the threat of infection or contagion, their political concerns and, in particular, their understanding of the relationship between territory and people, are bound to inform their decisions. Drawing on accounts of how different political regimes responded to outbreaks of infectious disease in the Mediterranean region in the past, this chapter focuses on how different regimes understand the spread of the disease: its movement across space. The rapid spread of COVID-19 during 2020 and the highly diverse political responses to it have demonstrated the importance of this point. Close the borders or not? Quarantine the population or not? The issue here is how people understand, organize and structure spatial relations and separations, as well as how they understand the disease in itself. Given that the spread of a disease involves movement across space, including the crossing of political borders, the way that location is understood and organized is important to how diverse peoples and regimes respond to the spread of disease. The question the chapter deals with is how diseases are located – in the Mediterranean region, in this case.

    The migration situation in the Mediterranean has been broadly publicized in global media over the past 5 years. The situation has arguably been branded the single most pressing migration crisis facing Europe at current and to be sure, the facts and trends have given cause for alarm – the consistently high number of migrant deaths at sea, the high burden on coastal states, and the concomitant reluctance if not outright refusal of states to adhere to moral humanitarian principles are all features of the current situation in the Mediterranean. The rescue of migrants at sea is governed by a fragmentary and complicated system of rules, actors, and instruments that both coexist and come into conflict with one another. While the responsibilities of states are codified in international legal instruments, it would appear that their actions, backed by domestic legislation, often clash with the moral codes of humanitarian and refugee rights. This thesis will attempt to demonstrate, using particularly the cases of the rescue vessel Aquarius as illustrative examples, the complexity of the international legal system and the discrepancies between, or at worst the decoupling of, different legal orders and between international and national (legal) action, and to view this complexity through a perspective of inter-legality. This thesis will inspect the international, regional and national legal instruments and legislation that have a bearing on the rescue of migrants in the Mediterranean through the examples of two rescue operations carried out in 2018 by an NGO-operated vessel, the Aquarius, and will argue that the example of the Aquarius provides an apt illustration of inter-legality at play.
