Geografia dos movimentos socioterritoriais no Brasil de 2000 à 2012

The struggle for land is not a recent theme in Brazilian history. Since colonization, people have fought and resisted against oppression and injustice in the countryside, as can be evidenced by the highwaymen, peasant leagues and the war of Canudos. More recently, the struggle for land and agrarian reform can be evidenced by the struggles of the MST, CONTAG, CPT and other movements. For these movements, denominated as socioterritorial movements, land/territory is an essential condition for their existence and for the maintenance of their territoriality. The present paper examines the geography of socioterritorial moviments: the construction of the concept of socioterritorial movements and their forms of action and scales of actuation in the period 2000 to 2012, focusing on the movements that have been most active. These movements are studied through as analysis of data of the Land Struggle Data Base (Banco de Dados da Luta pela Terra –DATALUTA), print and digital media reports and a bibliographic survey of the literature. The action of socioterritorial movements can be studied through the forms of land occupations and demonstrations in the countryside which are the principal means of the struggle against large landholders, agribusiness and the State. These actions question the model of development which privileges agribusiness and, as such, are viewed by some as a hindrance to the development of the country. Over the years, the number of socioterritorial moviments, and their actions have oscillated due to a series of factors, such as repression (criminalization of members and violence against them), policies adopted by Brazilian governments and the contradictions inherent in very process of the spacialization of the struggle for land. These actions can be analyzed according to the scale of the struggle of the movements – municipal, micro-regional, state, macro-regional, and national

A precarização do trabalho: migrantes nordestinos no município de Leme-SP : caminhos, estradas e sonhos

This paper aims to examine the genesis of migration to the city of Leme-SP, as well as the influence of the social matrix northeastern expansion and redevelopment through the territorialization of the migrant population, particularly workers from the state of Ceará, migration from the 1970s. This process is evidenced by the territorial division of labor, through the economic, political and cultural insecurity through the work of cutting sugar cane, the territoriality of culture and northeastern faith in the city, and becomes another object before the materiality in which occurs. In this aspect, through dialogue between the sciences and arts, it was possible to show the historical importance of the phenomenon of migration in the country, in different scales and relationship that encompasses everything and everyone

História natural de Hypsiboas albopunctatus (Anura: Hylidae) na região de Rio Claro, estado de São Paulo

Natural history studies aim to know where the organisms live, what they do, and their relationships within the environment, including the other organisms. The anurans, among other vertebrates, exhibits the greatest variety of reproductive modes as well as a high complexity of social organization, that may enable a lot of naturalist studies. Anurans modes of organization are direct related to parental care, vocalization of chorus organization, and with males territoriality. In general, the social organization is influenced by species reproductive pattern. This study aim to get information about the natural history of Hypsiboas albopunctatus (perereca-cabrinha) a species of the family Hylidae, on the region of Rio Claro Municipality, São Paulo State, Brazil. The major aspects discussed were: seasonality, spatial distribution, acoustic and visual communication, reproductive mode, reproductive site, abiotic factors influences, territoriality, courtship behaviour, satellite male behavior, embrace and defensive behavior. To obtain this data, nocturnal field excursions were realized monthly. Two sites of Rio Claro county where chosen as studies sites, the sítio Cantaclaro (22o19’36’’S; 47o42’57’’O), on the District of Itapé and Floresta Estadual Edmundo Navarro de Andrade (FEENA) (22o24’58’’S; 47o31’26’’O).

Território migratório - contigüidade socioterritorial de terras distintas: os Dekasseguis e a busca pela reterritorialização

This paper analyzes the new trends of Brazilian migration to Japan, more specifically in the process of redefining its territoriality on the political and administrative Japanese territory. This migration, known as Dekassegui movement, is based on the flow of Brazilians of Japanese descent in this country. The working part of a periodization of the movement, considering the political and economic situations of countries and account for aspects of the difficult adjustment of the pioneers, the change the temporal expectation of return and search for repossession of these immigrants in their most recent time frame After more than 27 years of migration is still common difficulties in the integrating the Brazilian front of Japanese society, and it is in this context, however, that migration projects take new directions, new meanings are created networks, strengthens relationships, change and so plans to build a new interaction with the territory. To understand this process, we consider as a theoretical analysis and territorial consolidation of field research in Japan, through questionnaires, to identify the processes of social integration of immigrants

Variable assessment of wing colouration in aerial contests of the red-winged damselfly Mnesarete pudica (Zygoptera, Calopterygidae)

Wing pigmentation is a trait that predicts the outcome of male contests in some damselflies. Thus, it is reasonable to suppose that males would have the ability to assess wing pigmentation and adjust investment in a fight according to the costs that the rival may potentially impose. Males of the damselfly Mnesarete pudica exhibit red-coloured wings and complex courtship behaviour and engage in striking male– male fights. In this study, we investigated male assessment behaviour during aerial contests. Theory suggests that the relationship between male resource-holding potential (RHP) and contest duration describes the kind of assessment adopted by males: self-assessment, opponent-only assessment or mutual assessment. A recent theory also suggests that weak and strong males exhibit variations in the assessment strategies adopted. We estimated male RHP through male body size and wing colouration (i.e. pigmentation, wing reflectance spectra and transmission spectra) and studied the relationship between male RHP and contest duration from videodocumented behavioural observations of naturally occurring individual contests in the field. The results showed that males with more opaque wings and larger red spots were more likely to win contests. The relationships between RHP and contest durations partly supported the self-assessment and the mutual assessment models. We then experimentally augmented the pigmented area of the wings, in order to evaluate whether strong and weak males assess rivals’ RHP through wing pigmentation. Our experimental manipulation, however, clearly demonstrated that strong males assess rivals’ wing pigmentation. We finally suggest that there is a variation in the assessment strategy adopted by males

Male and female interactions during courtship of the Neotropical damselfly Mnesarete pudica (Odonata: Calopterygidae)

The courtship behavior in calopterygid damselflies is well documented; however, the behavior of the large Neotropical genus Mnesarete is still unknown. Thus, here we present the first description of male-female interactions in Mnesarete pudica, a common damselfly in the Neotropical Savanna. The male-female interactions were composed of courtship displays, mounting, and chasing. The courtship behavior lasted 5.23 +/- 1.65 s and is very different from other calopterygids, consisting of hovering flights and the cross display made in front of females rather than on the oviposition site. The arrival and presence of females on a male territory are not sufficient to initiate sexual interactions; the male usually interacts with the female only after a patrolling flight. The females may present three distinct behaviors in response to male approach: (a) warding off signal (31.53%), (b) escape (28.83%), (c) and wing flipping (39.64%), which seems to stimulate male courtship. Females also may sit still, which induces males to react as if females were signaling they are willing to mate. In this paper, we also suggest that male courtship behavior is mediated by female signals.

Vocal and territorial behavior in the Smith frog (Hypsiboas faber): Relationships with plasma levels of corticosterone and testosterone

The possible trade-off between the roles of glucocorticoids as facilitators of energy substrate mobilization and neural inhibitors of sexual behavior during breeding season is under debate. We studied the relationship between calling and territorial behavior with plasma levels of corticosterone (CORT) and plasma levels of testosterone (T) across the breeding season of Hypsiboas faber, a large and territorial Neotropical treefrog. We investigated these relationships through focal observations of males calling naturally, followed by blood sampling for hormonal radioimmunoassay. We additionally used an experimental approach, which consisted of broadcasting recorded advertisement calls for 10 min to simulate an invasion in the territory of the focal subjects, followed by behavioral observation and blood sampling for hormonal radioimmunoassay. Results showed a pattern of co-variation between CORT and T across the breeding season. Furthermore, individual variation in CORT and T was related to different aspects of behavior: individuals with higher CORT showed higher calling rates, and individuals with higher steroid levels, mainly T, showed higher responsivity to social stimulation by other males in the chorus. Experimental simulation of territorial intrusion by using playback of advertisement calls of this species did not elicit consistent changes in agonistic behavior and CORT, but decreased T in focal males.

Insolvenza transfrontaliera e giurisdizione: l'esperienza del regolamento (CE) n. 1346 del 2000

L’elaborato è strutturato in quattro parti: la prima è dedicata all’inquadramento del background normativo. L’autrice affronta, con un approccio ricostruttivo, i precedenti alla redazione del regolamento e le difficoltà incontrate a causa delle resistenze degli Stati membri. Si sofferma altresì sulle norme UNCITRAL, anch’esse oggetto nel recente periodo, di numerose implementazioni. La seconda parte fotografa il ruolo della Corte di Giustizia nell’interpretazione del regolamento n. 1346/2000 ed individua i concetti fondamentali del regolamento: l’universalità attenuata, il campo di applicazione soggettivo del regolamento, la legge applicabile, il principio dell’automatico riconoscimento delle decisioni e la correlata tematica dell’ordine pubblico, nonché la figura del curatore. Si approfondisce l’attività degli Stati membri nel dotarsi di norme di coordinamento ( esemplare il caso della Spagna e della Germania) sottolineando il silenzio del legislatore italiano che, nonostante le numerose riforme in materia, a tutt’oggi non ha ideato un sistema in grado di coordinare la normativa nazionale con la struttura del regolamento europeo. Nella terza parte l'autrice approfondisce la giurisdizione nel regolamento n. 1346/2000. Si individuano le parole chiave: Comi e dipendenza, i cui significati sono sfumati seguendo le posizioni della Corte di Giustizia, (Leading Case Eurofood sino a Interedil) e si mette in discussione, nel panorama attuale, la tenuta di tali criteri giurisdizionali. Sempre intorno al concetto di Comi, si analizzano: la giurisdizione verso gruppi di imprese disciplina assente nel regolamento, i rapporti tra procedura principale e secondaria , la giurisdizione in materia di azioni connesse e/o correlate (Gourdain vs Nadler/Seagon vs Deko Marty). Il capitolo conclusivo offre una panoramica delle proposte finalizzate ad un’implementazione della struttura del regolamento sull’insolvenza. Numerose, infatti, sono le proposte a livello dottrinale e da parte degli organi comunitari in vista della scadenza del Report della Commissione Europea sulla applicazione del regolamento 1346 del 2000 (art. 46).
