Continental-scale decreases in shorebird populations in Australia

Decreases in shorebird populations are increasingly evident worldwide, especially in the East Asian–Australasian Flyway (EAAF). To arrest these declines, it is important to understand the scale of both the problem and the solutions. We analysed an expansive Australian citizen-science dataset, spanning the period 1973 to 2014, to explore factors related to differences in trends among shorebird populations in wetlands throughout Australia. Of seven resident Australian shorebird species, the four inland species exhibited continental decreases, whereas the three coastal species did not. Decreases in inland resident shorebirds were related to changes in availability of water at non-tidal wetlands, suggesting that degradation of wetlands in Australia’s interior is playing a role in these declines. For migratory shorebirds, the analyses revealed continental decreases in abundance in 12 of 19 species, and decreases in 17 of 19 in the southern half of Australia over the past 15 years. Many trends were strongly associated with continental gradients in latitude or longitude, suggesting some large-scale patterns in the decreases, with steeper declines often evident in southern Australia. After accounting for this effect, local variables did not explain variation in migratory shorebird trends between sites. Our results are consistent with other studies indicating that decreases in migratory shorebird populations in the EAAF are most likely being driven primarily by factors outside Australia. This reinforces the need for urgent overseas conservation actions. However, substantially heterogeneous trends within Australia, combined with declines of inland resident shorebirds indicate effective management of Australian shorebird habitat remains important.

Conglomerados financeiros: análise de seu desempenho no Brasil, no período de 1978/1981

o presente trabalho resulta de uma pesquisa de campo realizada na cidade de Porto Velho / RO, em 1990, junto a técnicos da área agrícola e da utilização de outras fontes de informações (secundárias), com o objetivo de conhecer as Políticas Públicas para o setor agrícola do Estado, identificar e analisar o seu resultado e apresentar sugestões para mudanças, considerando a população migrante. o estudo descreve e analisa as Políticas Públicas do Estado, apresenta uma visão histórica de sua formação econômica, fazendo uma reconstituição de seu passado das Fases do Extrativismo e Moderna. Analisamos a evolução de sua economia, ficando evidente que os fatos econômicos e sociais condicionaram o direcionamento de fluxos migratórios para Porto Velho, desde os seus primórdios, até hoje em proporções crescentes. Evidenciaram-se os problemas decorrentes da crescente urbanização das cidades afetadas pelo processo migratório, principalmente a população rural, as dificuldades encontradas por essa população, motivadas pela falta de políticas agrícolas adequadas. Constatou-se que as políticas agrícolas do Estado não estão sendo viáveis, face a diversos fatores, os quais são apontados no trabalho. Por fim, apontamos sugestões para uma proposta de reformulação da política para o Setor Agrícola, com vistas a superar grandes problemas na área, vividos principalmente pela população rural que migra para aquele Estado.

Migração interna populacional e sua participação no desenvolvimento regional no final do século XX

A divulgação dos primeiros blocos de resultados do Censo Demográfico de 2000 traz importantes oportunidades de constatação sobre os padrões de evolução e distribuição demográfica brasileira nos anos 90. Nesse sentido, ao tratar do comportamento reprodutivo, destaca a continuidade do declínio dos níveis de fecundidade, associando-o a mudanças na organização econômica e espacial. Quanto á mortalidade, ressalta-se sua queda sistemática nas últimas décadas. Por último, em relação ás migrações e redistribuição espacial da população, enfatizam -se as alterações nos fluxos migratórios recentes, a desaceleração do crescimento de algumas regiões metropolitanas e áreas do Sudeste , enquanto aumentam relativamente a retenção populacional no Nordeste e o deslocamento para o Norte e para o Centro-Oeste.

Immigration and memory

The town of Nova Friburgo, in Brazil, was founded in 1820 by swiss immigrants who, as often happens in the majority of migratory flows, crossed the ocean in search of better life conditions. The scope of this paper is to trail the path of a swiss immigrant called Marianne Joset Salusse and then follow on to investigate the mechanisms involved in elaborating family memory and public memory around this woman who would become a symbol of immigration to this town. Thus a series of interviews were held with her descendants, which were fundamental for the understanding of current representations and the main elements which constitute the collective memory around Marianne. Besides oral sources, we had recourse to written documents which allowed a retrieval of relevant information about her life. More than simply adding information, written sources allowed for a more profound analysis of oral accounts, unravelling as well as unveiling selective procedures peculiar to memory construction (Pollak, 1989;1992).

A reforma agraria e suas implicações no processo de desenvolvimento do Estado de Rondonia

Na década de 80 teve início o Programa de Desenvolvimento Integrado para o Noroeste do Brasil. Financiado pelo Governo Federal e o Banco Mundial sob coordenação do Governo Federal e execução de institutos federais e estaduais. Seria através do POLONOROESTE que as instituições chaves do Estado seriam criadas e/ou fortalecidas. O objetivo do POLONOROESTE era absorver o fluxo migratório de maneira coordenada e sustentável. E principalmente concluir o asfaltamento da BR-364. Na visão dos ambientalistas vários problemas surgiram a partir do POLONOROESTE. O próprio Banco Mundial chegou ã conclusão que o plano foi aplicado de forma precipitada, embora tivesse seus pontos positivos. Realizou-se em 1984 uma revisão de meio termo no programa. Apresentou, inicialmente, em versão preliminar o Zoneamento Sócio-Econômico-Ecológico que seria o instrumento básico de planejamento e ordenamento territorial. A partir de estudos feitos pelo Zoneamento Sócio-Econômico-Ecológico teve início o PLANAFLORO. O Brasil não pode estagnar seu desenvolvimento em nome da questão ambiental. O foco não é somente estratégico, mas uma questão de sobrevivência dos povos da floresta amazônica. Entendendo-se como povos da floresta todos os cidadãos que lá habitam. Inúmeros países formaram Comitês Internacionais de Defesa da Amazônia com o pensamento de que a posse da floresta amazônica pela Guiana inglesa, BrasiL Venezuela, Colômbia, Peru e Bolívia era meramente circunstancial. Que a floresta na verdade era patrimônio da humanidade. Esse nível de consciência pelo resto do mundo tem transcendido os limites da tranqüilidade dos países a que pertence a Amazônia. Problemas sociais como a denominada "chacina dos yanomamis" em Roraima, servem para que as ONG's procurem mostrar a incompetência do Brasil em administrar esse rico território.

Processos produtivos e trabalho-educação: a incorporação do caboclo catarinense na indústria madeireira

The object theme of the present study is a population of caboclos that absorbed as manual workers in the saw-mills which were mounted in the highland region of Santa Catarina since 1950. The abundance of araucaria (native kind of pine) the opening of markets, and the corroboration of other industrial exploration conditions encouraged a great crowd of small en.- trepreneurs, coming basically from the state of Rio Grande do Sul, to migrate and settle down, building up a lot of saw-mills near rich forests and fields. The saw-mills started aprosperous production of timber sawn in planks. The process of industriali zation was so intensive, the destruction of pine woods soviolent that, in less than three decades, the forests ran out of tree reserves. The caboclos, absorbed as manual workers in production of timber, lived traditionally in an system of subsistense, either from the cultivation of pine the economic their land (planter caboclo) or as labourers in cattle-growing farms (farm hand caboclos). Nevertheless, the 'advantages' that were offered them by the new-comer entrepreneurs (a salary paid in money, a new house in a village, and other favours) helped the great majority of caboclos to abandon their traditional work and enlist as "workmen" in saw-mills. The new job, besides being a novelty, was an opportunity for a change in status. Subsequently, the running out of forests of araucaria and the resultant progressive shut-down of saw-mills caused the crowd of workmen to be out of imployment and to form to form a migratory flood toward the most important town of the region, Lages. The town of Lages, however, having made of the timber i ts main economic support wi thout the implantation of an alternative industry, was unable to offer the migrantssufficient 'work places'. In this way, the 'marginal crowd' began to settle down in the suburbs of the city. This study, in the context of the object theme, analyses two main questions related to the reality 'WOlLQ' and to the economic exploitation forms: ~) the relations of production in the economic regime of subsistence and in the capitalist regime of industrial production with the consequent 'positions' of the workman in the productive processj ~~) the deriving educative effects of the productive process, either in the economic regime of subsistence, or in the capitalist industrial regime. The two questions are theoretically debated andconfro~ ted with the proposed reality, giving origin to conclusions that, in a general formulation, can be summarized as follows: a) the caboclos of the highland region of Santa Catari na, when under an economic regime of subsistence, held in fee the productive processj there was a social division of the work and aclimate of freedom which made possible the development of knowledge from their life and work experience, the production of most of their tools, and the making of necessary manufactures adapted to their own surrounding ditionsi -- - --- other con- ------ b) however, these same caboclos, when absorbed by the capitalist industrial process of production - tipified by the work in saw-mills - lost the control of the productive processj this was caused by the technologic division of the work, since each man began to perform a dull and repeti tive action, directed by the speed of the 'major-saw' j man resigned form his skill and inventive power and surrendered to an executive authority which turned him into a 'collective worker'j the new productive process, besides rnaking each rnan a copy of a pattern, put the caboclos in a situation in which the daily work experiencedidn't add anything in terrns of autogenesis of knowledgei and even the environrnental educative rneans were reduced to new forrns of adaptation to the productive process, relegating rnan's inventive power to inertia.

De gata borralheira a Cinderela :nova espacialidade decorrente do desenvolvimento turístico, diferenciada pelo estilo de vida em Ponta Negra, Natal, RN

The transformations economical, social and politics in you finish them decades of the century XX brought changes that didn't just limit to the production system. The flexible accumulation took many workers lost her/it their workstations and they look for her/it new survival forms, migrating for administrative activities, of services rendered and for the tourist activity of small and medium load. The State has been investing in the implantation of plans of tourist development in order to create favorable conditions for the reproduction of the tourist activity in Brazil, mainly in the Northeast. A space when it starts to present a predominant economical activity suffers a restructuring in their social and economical relationships. The restructuring of these relationships takes to the construction of a new espacialidade. In the city of Christmas, in Rio Grande do Norte, the neighborhood of Black Tip is the most representative of the public investments for the tourist development. After intense process of tourist urbanization, Black Tip passed interfering in the global context consolidating as the tourist locus in the city. The tourist urbanization of the neighborhood took to the transformation of the space in merchandise that is sold and consumed as such. The recreation of fragments of other cultures brought by social actors, resulting from migratory processes stimulated by the tourist development, it has been presenting ruled social relationships in the informational technology, consumption of global goods and in the fragmentation of the urban space characterized by the internationalization and cosmopolitização. That process has been masking the inequalities partners and cultural as well as the territorial appropriation for an economical elite. The spaces are being appropriate for investors of the tourist section, private investors, agents and real estate producers, where the inequality is not just economical, but also cultural. The local population, mainly of the urban fraction of the Town of Black Tip, it doesn't participate of the productive process in function of the little or any professional qualification and he/she doesn't also have access to the consumption process. To the native ones it remains the fight for the preservation of his/her cultural identity and for the survival

Efeito anti-inflamatório do heparinóide isolado do camarão Litopenaeus vannamei sobre a peritonite aguda

In recent years the heparin has been the subject of several studies that aim to expand its use as a therapeutic agent, due to its ability to modulate the activity of various proteins that play important roles in the regulation of pathophysiological processes. In several experiments and preclinical trials, heparin has demonstrated an anti-inflammatory role. However, its clinical use is limited, due to its strong anticoagulant activity and hemorrhagic complications. For this reason, considerable efforts have been employed in discovery of heparin analogous (heparinoid) with reduced side effects, that retain the anti-inflammatory properties of heparin. In this context, a heparinoid obtained from the head of Litopenaeus vannamei shrimp, which presents a structural similarity to heparin, showed, in previous studies, anti-inflammatory activity in a model of acute peritonitis with reduced anticoagulant effect in vitro and low hemorrhagic activity. Thus, the present work had as objective to evaluate the effect the heparinoid of the cephalothorax of gray shrimp on the acute inflammatory response in different times (3 or 6 hours after the induction of inflammatory stimulus), using the model of acute peritonitis induced in mice. It was also analyzed the HL effect over the activity of elastase, an enzyme involved in leukocyte recruitment. Furthermore to check if the different doses of heparin and heparinoid change the hemostatic balance in vivo, was assessed the effect of these compounds on the plasma clotting time in animals submitted to inflammation. The results show that in 3 hours, all doses of heparinoid were able to prevent efficiently in the acute inflammatory process without any anticoagulant effects, unlike the extrapolation dose of heparin, which has induced a large hemorrhage due its high anticoagulant activity. However, 6 hours after induction of inflammation, only the dosages of 0.1 and 1.0 μg/Kg of heparin and 1.0 μg/Kg of heparinoid kept anti-migratory effect, without changing of the hemostatic balance. These results indicate that the anti-migratory effect of theses compounds depends on the dosage and time of inflammatory stimulus. The HL and heparin were also able to inhibit the activity of the enzyme elastase. The discovery of this bioactive compound in the cephalothorax of shrimps can arouse great interest in biotechnology, since this compound could be useful as a structural model interesting for the development of new therapeutic agents for peritonitis

Growth, lipogenesis and body composition of piracanjuba (Brycon orbignyanus) fingerlings fed different dietary protein and lipid concentrations

Piracanjuba (Brycon orbignyanus) is a Brazilian migratory fast-growing omnivore, very appreciated as a sport fish, which is threatened to extinction in Southern Brazil due to stock over exploitation and dam building. Therefore, efforts have been made to raise this fish in captivity for reintroduction and aquaculture purposes. In the present study, the effects of different dietary protein and lipid concentrations on piracanjuba fingerlings growth performance, feed utilization, body composition, hepatosomatic index (HSI) and activity of the lipogenic enzymes fatty acid synthetase (FAS), glucose-6-phosphate dehydrogenase (G6PD) and malic enzyme (ME) were investigated using a 2 x 3 factorial experiment. Six casein-gelatin based diets were prepared combining two protein (30% and 32%) and three lipid concentrations (5.5%, 8.8% and 12.1%). Eleven fish, average weight 11.30 +/- 0.1 g, were held in each of 18 100-1 aquaria, supplied with recirculating freshwater. Each diet was randomly assigned to triplicate groups of fish and fed to apparent satiation, twice a day for 100 d. Piracanjuba fingerlings' daily weight gain (0.36-0.40 g), specific growth rate (1.43-1.51%), feed utilization and HSI were not influenced by dietary protein or lipid concentration. However, body composition was directly affected by dietary treatment. An increase in body fat and dry matter was observed as dietary lipid increased, for both dietary protein concentrations tested. The activity of FAS was depressed by increasing dietary fat levels but the G6PD activity did not differ among dietary treatments, although ME activity showed some regulation by dietary protein. These results indicate that an increase from 5.5% to 12.1% in the dietary lipid, at a dietary protein concentration of 30% or 32%, promotes body fat accumulation in piracanjuba fingerlings with no improvement in growth, suggesting that the lipid requirement for this species should be 5% or less, when raised for commercial purposes. However, the additional energy reserve from body fat accumulation could be desirable for piracanjuba fingerlings produced for stock enhancement.

O discurso religioso no processo migratório para o caldeirão do beato José Lourenço

The Caldeirão is a site located in the city of Crato, in the south of Ceará, belonged to priest Cícero Romão Batista. There, was created a religious community led by blessed José Lourenço, who marked the life of thousands of Northeast country people in 1930s, for represent to them a space of religious conviviality, work and devotion. The Caldeirão s population was about three thousand of people, originated from states of Pernambuco, Alagoas, Paraíba, Maranhão, Piauí, Ceará and Rio Grande do Norte, who share the community s daily activities. The misery caused by the dryness and exploration of these country people by the landlords are indicated as the motivator elements of this migratory flux by the greater number of works published about the Caldeirão, turning the community into a primitive experience of class struggles. This present study proposes other comprehension of this migratory movement by the religious speech of salvation taken to country people by the counselor Severino Tavares. Was used as analysis camp the remaining norte-rio-grandenses that migrated to the Caldeirão, and as theoretical and methodological references the understanding model of investigation, the cultural history and the remaining memorial speech analysis. The work follows that pointing the phenomenon of Caldeirão as an campestral revolt is try to impose to this people the aspirations or wishes of others, besides of deny to them the right and the dignity of act by their believes and their own dreams.

Modos de ser e modos de viver : a trajetória dos estrangeiros em Natal/RN

This work aims to understand the trajectory of immigrants living in Natal / RN, between the years 1990 and 2009, their motivations for this change, their sociability relations, as well as the impact of this group in Natal and specifically, in the district of Ponta Negra, where most of them established their residences or work. Considering that the historical, political, economical and social environment where these immigrants are inserted, are different from that experienced by former immigrants who came to Brazil in the late nineteenth and early twentieth centuries, a period of mass migration, it was revealed that immigration studied in contemporary Natal constitutes a new configuration (Elias, 1994). This new configuration is represented by several characteristics that distinguish this contemporary immigration, as: the relationship established by these foreigners, both with their country of origin and the destination, the formation of social networks that offer support to newcomers and those already installed, the relations of sociability with locals and a new relationship of belonging with the space, since the possibility of coming and going from one country to the other, allows a (re)production of their original ?? social and economic life in the new space. The research methodology was based on the analysis of narrative interviews, in light of the theory of Schütze (1977) in order to understand the faces of this immigration. As theoretical support for the data analysis the theories of authors such as Norbert Elias, presentedin his work about the established and outsiders, Pierre Bourdieu, and his concept of habitus, distinction and style of life, Georg Simmel, and his study of life in the metropolis, his analysis of the foreigner and his theory of sociability, among others. This study attempted to give visibility to foreigners living in Natal, who experience the dynamics of the district of Ponta Negra and reconstruct their daily relations of sociability in this space. In fact, the presence of foreigners in this urban context allows for the construction of new configurations, both in terms of the physical space of the neighborhood, which has been modified by the touristification process and the real estate market, which is molded to meet this demand, but also in their social sphere, with regard to the relations established between foreign residents and locals. In seeking to characterize these migratory experiences it could be understood that the trajectories of each foreigner is part of a broader social structure, which cannot be evaluated neither disconnected from the contexts in which they operate, nor under a single point of view

Hematological parameters in two neotropical freshwater teleost, Leporinus macrocephalus (Anostomidae) and Prochilodus lineatus (Prochilodontidae)

Leporinus macrocephalus is a non-migratory omnivore fish which occurs in waters with a relatively high oxygen rate. Prochilodus lineatus is a migratory fish that inhabits deoxygenated hypolimnion and feeds on detritus material. Red blood cell, thrombocytes and white blood cell counts, hematocrit and hemoglobin, serum electrolytes (sodium, potassium, calcium, magnesium and chloride), metabolic products (total serum protein and plasma glucose) and blood cells major axis length for L. macrocephalus and P. lineatus were compared. White blood cell counts for both species indicated a similar activity of the immune functions. The concentration of total protein, sodium, calcium, magnesium and chloride, MCV, as well as red blood cells, monocytes, and thrombocytes size in L. macrocephalus were higher than in P. lineatus. However, P. lineatus had higher red blood cell counts, hematocrit and hemoglobin, which reflects a considerable adaptation to survive in an environment with low levels of oxygen.

Um imperialismo possível: fluxos migratórios e estratégias colonialistas na Europa mediterrânea (1870-1914)

Este artigo analisa algumas das diferentes implicações do fluxo migratório nos principais países fornecedores de contingentes, durante o período conhecido como new emigration: Itália, Espanha e Portugal. Considerando suas especificidades, o objetivo é identificar as estratégias de cada um para transformar esse movimento em fator de desenvolvimento econômico: conquista de mercados, criação e fomento de colônias, incorporação e tutela das remessas dos emigrados. Reino em formação e maior fonte de emigrantes, a Itália seguiu naturalmente os caminhos que identificavam a emigração como um dos agentes de prosperidade da nação, contrastando com Portugal e Espanha.
