Phenotypic Flexibility in the Social Organization of Clethrionomys

1990

I review the flexibility of social organization and spacing behavior in Clethrionomys. This review is based on a 6-year comparative study and several experimental studies on cyclic populations of the bank vole, C. glareolus, in Central Finland. The social organization of Clethrionomys populations shows great flexibility during both the breeding and nonbreeding season, and is dependent on habitat patchiness, food availability, Predation, kinship, philopatry, and familiarity between individuals. The first three factors are most important in destabilizing a population, whereas the last three stabilize a population without exhausting its resources. Female territoriality can weaken in a producti…

Basic knowledge of social hierarchies and physiological profile of reared sea bass Dicentrarchus labrax (L.).

2019

The effects of social hierarchies (dominant/subordinate individuals), such as aggressiveness, feeding order, and territoriality, are some of the characteristics used for describing fish behaviour. Social hierarchy patterns are still poorly understood in European-reared sea bass (Dicentrarchus labrax). In this work, we examine the social interactions among captive fish integrating behavioural and physiological profiles. Groups of three fish with EMG (electromyogram) radio transmitters were monitored for two weeks via video recording. Plasma levels of cortisol, glucose, lactate and lysozyme as well as haematological parameters such as haemoglobin, haematocrit and RBCC (red blood cell count) w…

Beyond ‘nasty neighbours’ and ‘dear enemies’? Individual recognition by scent marks in a lizard (Podarcis hispanica)

2008

True individual recognition (TIR), the ability to recognize conspecific individuals on the basis of identity cues, is required for the evolution of several social traits (e.g. the maintenance of dominance hierarchies). However, knowledge about the distribution and functional significance of TIR is scant in some vertebrate groups, such as reptiles. In this study we used a functional modification of a habituation-dishabituation paradigm to investigate the existence and adaptive significance of TIR in a territorial lizard (Podarcis hispanica, Lacertidae). Males discriminated between individual rivals of similar characteristics (e.g. size, weight, familiarity) solely on the basis of their scent…

Abitare il confine. Spazio, territorialità e dilemmi dello sviluppo

2013

L'articolo esplora criticamente la vicenda dell’isola di Lampedusa, oggetto negli ultimi anni di ingenti flussi di immigrati, da una prospettiva che guarda allo sviluppo locale e alle forme di territorialità come espressione di processi generativi complessi e peculiari. Tali processi, infatti, mettono in gioco nel tempo le relazioni tra popolazioni e risorse, sullo sfondo di scenari geopolitici e condizioni contestuali quali il Mediterraneo, con il suo carico di ambiguità, la condizione di insularità e di confine, il tempo quale fonte generatrice di eventi inattesi e sviluppi imprevedibili.

Extraterritorial Jurisdiction in International Law

2015

Application of internal law by a state beyond its own territory is an extraordinary action in international law. It requires not only a solid justification but is also subject to many restrictions. It often comes to conflicts against this background that is why extraterritorial jurisdiction is considered as a dangerous but yet an effective instrument of foreign politics. The article not only provides a concise definitions of extraterritoriality but also points to its acceptable bases (liaisons) and restrictions. Moreover, a review of interesting, representative doctrine stances has been done. Controversies and dangers related to the discussed institution are explicitly emphasized. In contra…

Mediterranean regionalism from territory to trains: spatial politics and planning of macro-regions and transport networks in Spain

2015

The contested planning of European macro-regions and Trans-European Transport Network (TEN-T) exemplifies the complexities of spatial politics, territorial and relational. What stratagems – discursive and cartographic – may regional actors employ in the process, and what can we learn from them? In context of European Union integration policies, we explore Spanish regional politics – discursive and cartographic – surrounding planning of cross-border regions and a TEN-T “Mediterranean Corridor” (and its alternatives). The contested remapping of macro-regions and transport networks reveals the role of spatial planning in the vertebracio (structuration in Catalan) of European territory in disti…

Poison frog social behaviour under global change: potential impacts and future challenges 

2022

AbstractThe current and cascading effects of global change challenges the interactions both between animal individuals (i.e. social and sexual behaviour) and the environment they inhabit. Amphibians are an ecologically diverse class with a wide range of social and sexual behaviours, making them a compelling model to understand the potential adaptations of animals faced with the effects of human-induced rapid environmental changes (HIREC). Poison frogs (Dendrobatoidea) are a particularly interesting system, as they display diverse social behaviours that are shaped by conspecific and environmental interactions, thus offering a tractable system to investigate how closely related species may re…

Septal complex of the telencephalon of lizards: III. Efferent connections and general discussion.

1998

The projections of the septum of the lizard Podarcis hispanica (Lacertidae) were studied by combining retrograde and anterograde neuroanatomical tracing. The results confirm the classification of septal nuclei into three main divisions. The nuclei composing the central septal division (anterior, lateral, medial, dorsolateral, and ventrolateral nuclei) displayed differential projections to the basal telencephalon, preoptic and anterior hypothalamus, lateral hypothalamic area, dorsal hypothalamus, mammillary complex, dorsomedial anterior thalamus, ventral tegmental area, interpeduncular nucleus, raphe nucleus, torus semicircularis pars laminaris, reptilian A8 nucleus/ substantia nigra and cen…

Conflicts of Jurisdiction in Criminal Proceedings in Europe: Between Bis In Idem and Lis Pendens

2018

The purpose of this paper is to highlight the main issues concerning conflicts of jurisdiction within the EU, also from an italian perspective. The reason of conflicts of jurisdiction’s increase lies in the non-full application of the territoriality criterion, but especially in the transformation of criminality: the opening of borders and free movement of people, as well as the using of IT tools, can cause a fragmentation, among different countries, in the commission of crimes. The discussion on the overlap of proceedings for the same facts involving the same person revolves around various sources of law. Because of interpretative difficulties, many questions regarding conflicts of jurisdic…
