Abstract:
Migratory species can experience limiting factors at different locations and during different periods of their annual cycle. In migratory birds, these factors may even occur in different hemispheres. Therefore, identifying the distribution of populations throughout their annual cycle (i.e., migratory connectivity) can reveal the complex ecological and evolutionary relationships that link species and ecosystems across the globe and illuminate where and how limiting factors influence population trends. A growing body of literature continues to identify species that exhibit weak connectivity wherein individuals from distinct breeding areas co-occur during the nonbreeding period. A detailed account of a broadly distributed species exhibiting strong migratory connectivity in which nonbreeding isolation of populations is associated with differential population trends remains undescribed. Here, we present a range-wide assessment of the nonbreeding distribution and migratory connectivity of two broadly dispersed Nearctic-Neotropical migratory songbirds. We used geolocators to track the movements of 70Vermivorawarblers from sites spanning their breeding distribution in eastern North America and identified links between breeding populations and nonbreeding areas. Unlike blue-winged warblers (Vermivora cyanoptera), breeding populations of golden-winged warblers (Vermivora chrysoptera) exhibited strong migratory connectivity, which was associated with historical trends in breeding populations: stable for populations that winter in Central America and declining for those that winter in northern South America.

Abstract:
From the dawn of civilisation, locusts have been one of the great agricultural plagues, stripping vast areas bare of vegetation as they relentlessly advance. Experience shows that the most effective control measure is to attack the pest at its breeding grounds in the Niger Delta area as soon as it shows signs of swarming. Unfortunately, the prolonged sahelian drought – which for some years has put a natural brake on breeding – has encouraged complacency about the risks of another resurgence when this comes to an end.

Abstract:
Abstract Counts of visible migrants at traditional watchsites throughout North America provide an opportunity to augment population-monitoring efforts for birds of prey. We analyzed hourly counts of migrating raptors at one inland (Hawk Mountain Sanctuary, Pennsylvania) and one coastal (Cape May Point, New Jersey) watchsite in northeastern North America. Hourly counts of migrants have been collected for 38 years at Hawk Mountain Sanctuary and for 28 years at Cape May Point. We compared effort-adjusted, arithmetic-mean passage rates to five geometric-mean indexes for 12 species. We used reparameterized polynomial regression to estimate trends in the indexes and to test the significance of trends from 1976–1978 (average index over three-year period) to 2001–2003. Effort-adjusted, arithmetic-mean indexes corresponded to more sophisticated indexes on the complete data sets but did not perform well on simulated data with missing observation days. We recommend the use of a regression-based, date-adjusted index for the analysis of hawk-count data. This index produced trends similar to other geometric-mean indexes, performed well on data sets simulating reduced sampling frequency, and outperformed other indexes on data sets with large blocks of missing observation days. Correspondence between trends at the watchsites and trends from Breeding Bird Surveys (BBSs) suggests that migration counts provide robust estimates of population trends for raptors. Furthermore, migration counts allow the monitoring of species not detected by BBS and produce trends with greater precision for species sampled by both methods. Analysis of migration counts with appropriate methods holds considerable promise for contributing to the development of integrated strategies to monitor raptor populations.

Abstract:
Labor force trends up to 2025 for the fifteen countries (before May 1, 2004) of the European Community are examined. Will demographic decline have an early effect on manpower volume? An estimation is made to determine whether present migratory flow levels in these countries will be sufficient to counter labor force stagnation. Manpower trend scenarios are proposed for each country. They show highly contrasting situations. These countries favor different policies for mobilizing and increasing their manpower volume. There is wide divergence between the various EU countries as concerns their demographic situation and labor force participation rate as well as their social security systems. Considering these highly diverse national characteristics, the difficulty in arriving at a consensus on EU migratory policy harmonization is stressed.

Abstract:
Migratory shorebirds are declining in all transequatorial flyways, most rapidly in the East Asian–Australasian Flyway. Population trends for shorebirds have been derived at a flyway and continental scale, but changes at the local scale are less well understood. Here we compare trends in migratory shorebird populations using natural and artificial roost sites within a tropical harbour, examine possible drivers of change, and identify appropriate conservation management responses. Counts of 19 migratory shorebird species from 2010 and 2018 showed that total abundance increased at an average annual rate of 3.3% (95% CI=1.3–5.4%, P=0.001) across five natural roost sites. This was driven largely by increases in great knot, with most other species declining. At an artificial site in an adjacent shorebird area, total abundance increased at an average annual rate of 14.5% (95% CI=10.5–18.6%, P ≤ 0.000), with few species declining. These results suggest that there is a need to include both natural and artificial sites within shorebird conservation and management planning and that trends in different species can be driven by a combination of local and external drivers.

Abstract:
Portuguese waters are an important migratory corridor for European seabirds and coast-based counts can be used to monitor local and global populations and to study the long-term trends in seabird populations. After 10 years of counts in seven different sites along the Portuguese coast, we aimed to identify the period of occurrence and distribution areas of the seven most common seabird species, evaluate abundance trends and associations with potential oceanographic drivers. The trim model was able to estimate the trend for most of the species with the Balearic Shearwater, the Great Skua, and the post-breeding populations of Sandwich Tern and Common Scoter presenting strong negative trends. The Mediterranean Gull and the Northern Gannet during the pre-breeding migration show a moderate increase. The GAMs found that the abiotic parameters that most often had a significant influence in the models were sea surface temperature, ocean mixed layer thickness and eastward wind speed; O uso da costa Portuguesa pelas aves marinhas migratórias Resumo: As águas portuguesas são um importante corredor migratório para as aves marinhas europeias e, contagens a partir da costa podem ser utilizadas para monitorizar e mostrar as tendências a longo prazo das populações de aves marinhas. Após 10 anos de contagens, pretendeu-se identificar o período de ocorrência e áreas de distribuição das sete espécies mais comuns, avaliar as tendências de abundância e potenciais associações com variáveis ambientais. O trim estimou a tendência para quase todas as espécies, com a pardela-balear, o alcaide e, as populações pósreprodutoras de garajau-de-bico-preto e da negrola a apresentarem acentuadas tendências negativas. A gaivota-de-cabeça-preta e a população pré-reprodutora do alcatraz apresentam um aumento moderado. Os GAMs indicam que os parâmetros abióticos que mais frequentemente tiveram uma influência significativa nos modelos foram a temperatura da superfície do mar, a espessura da camada mista do oceano e a velocidade do vento vindo de Este.

Abstract:
Depuis une trentaine d’années, les recherches sur l’immigration italienne en France se sont multipliées. Néanmoins, pour certaines régions, dont la Franche-Comté, les études manquent. En se concentrant sur le courant migratoire avec la province de Trente, l’objectif est d’apporter un éclairage nouveau, pluridisciplinaire et international. De plus, la valeur heuristique de la comparaison permet de donner une perspective « glocale » : les aspects locaux sont sans cesse replacés dans un cadre national et mondial. Dans un premier temps, nous nous concentrons sur le mouvement migratoire trentin le replaçant dans un contexte chronologique plus large et abordant dans sa globalité ce phénomène, véritable mosaïque d’itinéraires, de destinations et d’histoires de vie. Dans un second temps, la thèse s’attarde sur le pays d’arrivée dans une perspective nationale d’abord, dans une perspective régionale ensuite. L’immigration italienne est étudiée pour l’ensemble de la région pour ensuite mettre en évidence le courant migratoire entre le Sud du Trentin (particulièrement des vallées du Leno) et le Nord Franche-Comté (Belfort, Montbéliard, Delle). Enfin, la partie principale est consacrée aux migrants, à leur adaptation, principalement à partir des années 20 jusqu’à nos jours. Le croisement de plusieurs types de sources (archives, entretiens oraux etc. ) permet de construire une analyse mêlant éléments culturels, historiques, littéraires et sociologiques qui semble montrer que le modèle français d’assimilation/intégration a très bien fonctionné. Ce travail se termine par des comparaisons d’autres courants migratoires trentins ou plus récents, en France et dans le monde<br>Research on Italian immigration to France has considerably increased over the last thirty years. However, for some regions, including Franche-Comté, no doctoral theses have as yet been devoted to the subject. Through example of the migratory trend between this region and the Province of Trento, this dissertation aims to offer a pluridisciplinary and international contribution to scholarship. Moreover, the heuristic value of comparison gives it a “glocal” perspective: local aspects are continuously seen both nationally and globally. The first part dwells on migratory movement from Trentino. It is presented within a broader historical context, this phenomenon needing indeed to be seen comprehensively as it represents a mosaic of itineraries, destinations and lives. Secondly, the focus shifts to the immigration country. Italian immigration is examined for the whole region in order to evidence the migratory trend between the South of Trentino (especially from the Leno valleys) and the North of Franche-Comté (Belfort, Montbéliard, Delle). Finally, the third and main part of the dissertation deals with the migrants themselves, and how they have adapted, chiefly from the 1920s up to the present. By confronting various different types of source (archives, oral interview etc. ) it has been possible to construct an analysis model with cultural, historical, literary and sociological elements. The results would seem to prove that the French assimilation/integration model has been largely successful. This study ends by comparing these conclusions with other migration trends from Trentino or from other countries, both in France and throughout the world

A procura de água conduziu à necessidade do represamento do recurso e à construção de barragens e açudes que comprometem a conetividade longitudinal e as movimentações das populações de peixes migradores. Este efeito pode ser mitigado pela construção de Passagens para Peixes (PPP). O presente estudo, realizado no âmbito do Programa de Monitorização da Passagem para Peixes do Açude-Ponte de Coimbra, entre Janeiro e Junho de 2013, pretendeu otimizar a metodologia de contagem visual dos peixes que utilizam o dispositivo e relacionar essa utilização com variáveis abióticas. A utilização da PPP por parte das espécies diádromas foi sobretudo regulada pelo caudal. Para as espécies potamódromas, além do caudal outros preditores foram identificados como a temperatura e a turbidez. O pico de utilização da PPP foram os meses de Março e Abril para a lampreia-marinha, Abril e Maio para o sável, savelha e barbo do Norte e entre Janeiro e Abril para a boga-comum; ### ABSTRACT: Monitoring of Açude-Ponte fishway in Coimbra: Optimization of counting methodology. Water demand has led to the need of the impoundment of the resource and the construction of dams, that compromise the longitudinal connectivity of the rivers, impacting the populations of migratory fish. This effect can be mitigated with the construction of fishways. This work, that was performed under the monitoring of the Açude-Ponte fishway in Coimbra, and between January and June of 2013, was intended to optimize the methodology of visual counting of the fish, and relate this pattern of use with abiotic variables. The use of the fishway by the diadromous species was mainly regulated by the flow. For potamodromous species, in addition to the influence of flow, other predictors were identified, such as temperature and turbidity. The peak use of the fishway occurred in March and April for the sea lamprey, April and May for allis shad, twaite Shad and Iberian barbel and the period between January and April for Iberian nase.

Population development and emigration of Maghreb's countries Abstract The main aim of diploma thesis is to map the migratory situation and trends of all area since 1990 up to the present in context of the population development in region of Maghreb's countries. This all is in connection with the population growth of the states - natural and total. Apart from the analysis of the whole Maghreb as one unit, the demographic parameters are in detail assessed on the example Tunisia. It is estimated that migratory streams of the inhabitants of North Africa's countries are largely directed to Europe. The analasis is focused on the breakdown of the target countries, emigrants and on changes during the reporting period. The analasis uses conventional demographic indicators, its own methods of processing often difficult available data at the same time and empirical investigation. The initial basis of analyzing given issues show the theoretical conception of population development in Arabic countries, with emphasis on demographic transition and dependent migratory transition. Analysis revealed that none of Maghreb's countries has not yet completed demographic transition, the second stage of the demographic transition since 2000 suspended.

Abstract:
The growing share of skilled and highly-skilled, often unmarried, young Arab women immigrating to the GCC is generally un-documented. Shedding some light on this population, therefore, will not only emphasize a new phenomenon, but it also, first, points at a new structural trend within Arab populations: the emergence of educated female professionals in Arab societies characterized by low female activity rates. Second, it challenges the dominant assumption that Arab migration to Gulf countries is a “male-only” phenomenon in which women are married dependents. This contribution aims at laying some ground to bridge the knowledge gap regarding Arab female highly-skilled workers in the Gulf. The study explores the proximate determinants—rise in age at marriage, development of female celibacy in the Arab world, expansion of female education levels—and structural conditions compelling an increasing number of Arab citizens, male and female, to seek better futures abroad. Findings, such as the widespread denial that patriarchal pressures are important factors in determining Arab female migration, question the categories used, including Arab, female, and Gulf migration patterns. The study also concludes that such partial results beg to be completed by a wider-scale survey involving highly-skilled female migrants from several Arab countries and systematically comparing their migratory patterns and experience.

Abstract:
Il n’a que 14 ans. En 1956, István Borsodi pense choisir la liberté en traversant le Rideau de fer. Il quitte une Hongrie morose – où la Révolution contre l’occupant soviétique a été écrasée – et rejoint la Suisse. István se souvient de son arrivée en terres helvétiques, des applaudissements, « des gens qui venaient nous saluer » dans chaque gare où le convoi spécial faisait halte. Il a conservé la première carte postale destinée à sa famille restée en Hongrie « Je suis à Bière, je me sens bien, j’embrasse tout le monde ». Mais, après quelques temps, le mal du pays, l’ennui des proches commencent à le ronger et ses perspectives professionnelles en Suisse sont moins attrayantes que ce qu’il imaginait. Sa tante restée au pays lui écrit que les jeunes rapatriés bénéficient d’une amnistie. En 1959, István Borsodi choisit alors de rentrer dans la Hongrie de János Kádár. Cet ouvrage retrace l’exode de quelque 200 000 Hongroises et Hongrois de 1956, l’arrivée d’une partie d’entre eux en Suisse, avant d’éclairer le parcours de celles et ceux qui ont décidé de rentrer en Hongrie quelques semaines, mois ou années après leur exil. Ce phénomène migratoire « à contre sens » est au coeur de ce livre. Arrivés dans le « paradis capitaliste » des Trente glorieuses, pourquoi ces personnes choisissent de rejoindre l’ « enfer » communiste ?

El libro se centra en el trabajo de tres organizaciones pioneras en estos esfuerzos: el Bachillerato Popular Trans Mocha Celis, OTRANS Argentina y la Universidad Nacional de Avellaneda. Travar el saber es una frase asociada a Lohana Berkins, una de las principales referentas de movimientos sociales y militancias trans y travesti. Berkins lo define así: "cuando una trava va a la universidad, cambia la vida de la trans; cuando muchas travas van a la universidad, cambia la institución". Este libro cristaliza la importancia de este cambio estructural, señalando el impacto de factores como la aceptación familiar, el acceso al trabajo, y el estatus migratorio, entre otros. &lt;i&gt;Travar el saber&lt;/i&gt; evoca la lucha histórica y el anhelo revolucionario de este colectivo, no por la inclusión dentro de un sistema excluyente, sino por la transformación radical de las categorías e instituciones que lo sostienen y reproducen; entre ellas, de manera principal, la educación.

Abstract:
AbstractThis chapter analyses the relationship between migration and social mobility in Argentina and Spain from a transnational perspective focusing on two dimensions: the patterns of intergenerational social mobility of immigrants and natives in both countries; the social mobility strategies and trajectories of Galicians families in Buenos Aires and Argentinians, of Galician origin, who migrated to Galicia after the 2001 crisis. The chapter begins by contextualizing the migratory trends in Europe and Latin America. This is followed by a comparative study of how immigration impacts on the class structure and social mobility patterns in Argentina and Spain. Quantitative analysis techniques are used to study the intergenerational social mobility rates. The statistical analysis of stratification and social mobility surveys have been benchmarked against previous studies conducted in Argentina (Germani, G., Movilidad social en la sociedad industrial. EUDEBA, Buenos Aires, 1963; Dalle, P., Movilidad social desde las clases populares. Un estudio sociológico en el Área Metropolitana de Buenos Aires (1960–2013). CLACSO/Instituto de Investigaciones Gino Germani-UBA/CICCUS, Buenos Aires, 2016) and Spain (Fachelli, S., &amp; López-Roldán, P., Revista Española de Sociología 26:1–20, 2017). Secondly, qualitative research methods are used to consider the social mobility strategies and class trajectories of migrant families. We analyse two fieldworks, developed in the framework of other research projects (based on 44 biographical and semi-structured interviews). These case studies were carried out with Galicians that migrated to Argentina between 1940 and 1960 and Argentinians, of Galician origin, who migrated to Galicia after the 2001 crisis.

Abstract:
Studies of the timing (phenology) of bird migration provided some of the first evidence for the effects of climate change on organisms. Since the rate of climate change is uneven across the globe, with northern latitudes experiencing faster warming trends than tropical areas, animals moving across latitudes are subject to diverging trends of climate change at different stages of their annual life cycle, and, consequently, they can become mistimed with the local ecological conditions, with potentially negative effects on population size. This chapter reviews the modifications induced by climate change in different migration traits, like the timing of migration events, the distribution of organisms, and the direction and the speed of movements. It also considers the effects of ecological carry-over effects and migratory connectivity on the response of birds to climate change.

Abstract:
This chapter is based on the Hungarian Youth Research 2012, in which 8000 young people aged 15-29 were interviewed within a national representative sociological examination. In this study, the issue of international migration, especially of foreign employment trends, and the mobility intentions and attitudes of young Hungarians in terms of gender differences are examined.The global social contexts of the migration process in Hungary are examined through the theory of dual or segmented labor market, mobility theories, and models of integration. In 2011, many European Union's member states opened their labor markets to Hungarian workers, so more and more young people consider working abroad within the legal framework as an attractive prospect. This chapter analyzed what causes and motivations lie behind international migration, and what factors influenced young Hungarians to work or study abroad. It also discussed the factors that increase or hinder the migratory propensity, and the differences of opinion between young women and men.

Abstract:
The history of conflict between double-crested cormorants and human interest in fisheries is long and convoluted. Overall, double-crested cormorants are not major consumers of commercial and sportfish species. However, exceptions have been recorded at specific sites with documented impacts on local fisheries. Double-crested cormorants can have a significant impact on vegetation at breeding sites through normal nesting activities. Their guano is acidic and can change soil chemistry, killing ground vegetation and irreversibly damaging nest trees. Humans should avoid direct contact with excrement from wildlife, including droppings from cormorants. The U.S. Fish and Wildlife Service (USFWS) has the primary responsibility and authority for managing migratory bird populations in the U.S. This publication will focus on the double-crested cormorant, which is the most numerous and widely dispersed of the species.

Abstract:
La inestabilidad social, política y económica en Venezuela ha generado cambios en los patrones migratorios de la región en los últimos años, con millones de venezolanos en busca de oportunidades laborales o mejorar el sustento para las familias que dejan atrás. En este contexto, las remesas tienen un papel fundamental como componente del ingreso disponible de los hogares receptores. En este estudio, analizamos como estos flujos monetarios en el contexto de una crisis migratoria se convierte en una estrategia de vida para hacer frente a la inseguridad alimentaria que enfrentan los hogares venezolanos. Con base a los datos de la Encuesta Nacional de Condiciones de Vida (ENCOVI) de 2019, estimamos un modelo con variables instrumentales para medir los efectos de las remesas sobre tres medidas de seguridad alimentaria. Hallamos que ser receptor de remesas está asociado con un incremento en el consumo calórico y la diversidad alimentaria de los hogares y una reducción en sus limitaciones de acceso a los alimentos.
