Abstract:

Abstract There is a growing body of evidence demonstrating the impacts of human arrival in new “pristine” environments, including terrestrial habitat alterations and species extinctions. However, the effects of marine resource utilization prior to industrialized whaling, sealing, and fishing have largely remained understudied. The expansion of the Norse across the North Atlantic offers a rare opportunity to study the effects of human arrival and early exploitation of marine resources. Today, there is no local population of walruses on Iceland, however, skeletal remains, place names, and written sources suggest that walruses existed, and were hunted by the Norse during the Settlement and Commonwealth periods (870–1262 AD). This study investigates the timing, geographic distribution, and genetic identity of walruses in Iceland by combining historical information, place names, radiocarbon dating, and genomic analyses. The results support a genetically distinct, local population of walruses that went extinct shortly after Norse settlement. The high value of walrus products such as ivory on international markets likely led to intense hunting pressure, which—potentially exacerbated by a warming climate and volcanism—resulted in the extinction of walrus on Iceland. We show that commercial hunting, economic incentives, and trade networks as early as the Viking Age were of sufficient scale and intensity to result in significant, irreversible ecological impacts on the marine environment. This is to one of the earliest examples of local extinction of a marine species following human arrival, during the very beginning of commercial marine exploitation.

Abstract:

Bone samples from the Greenland Viking colony provide us with a unique opportunity to test and use 14C dating of remains of humans who depended upon food of mixed marine and terrestrial origin. We investigated the skeletons of 27 Greenland Norse people excavated from churchyard burials from the late 10th to the middle 15th century. The stable carbon isotopic composition (δ13C) of the bone collagen reveals that the diet of the Greenland Norse changed dramatically from predominantly terrestrial food at the time of Eric the Red around AD 1000 to predominantly marine food toward the end of the settlement period around AD 1450. We find that it is possible to 14C-date these bones of mixed marine and terrestrial origin precisely when proper correction for the marine reservoir effect (the 14C age difference between terrestrial and marine organisms) is taken into account. From the dietary information obtained via the δ13C values of the bones We have calculated individual reservoir age corrections for the measured 14C ages of each skeleton. The reservoir age corrections were calibrated by comparing the 14C dates of 3 highly marine skeletons with the 14C dates of their terrestrial grave clothes. The calibrated ages of all 27 skeletons from different parts of the Norse settlement obtained by this method are found to be consistent with available historical and archaeological chronology. The evidence for a change in subsistence from terrestrial to marine food is an important clue to the old puzzle of the disappearance of the Greenland Norse, obtained here for the first time by measurements on the remains of the people themselves instead of by more indirect methods like kitchen-midden analysis.

Abstract:

In response to the threat posed by marine and river erosion, a series of deeply stratified midden deposits was excavated in caves leading off a narrow, rock-cut inlet known as the Geodha Smoo, near Durness, Sutherland. These included the famous Smoo Cave (NGR: NC 4136 6714), at the southern end of the inlet; two smaller caves cut into the western wall of the inlet (Glassknapper's Cave and Antler Cave); and a fourth cave (Wetweather Cave) in the eastern wall. The majority of excavated deposits from these caves appear to relate to Viking/Norse or post-Norse activity, with fish bones, marine shells and mammal and bird bones representing the processing and consumption of marine and terrestrial foods. Possible evidence for metalsmithing in the form of iron slag and boat nails could suggest that boats were repaired in the sheltered inlet. Four radiocarbon dates from Smoo Cave and Glassknapper's Cave provide evidence for use of these sites between the eighth and 11th centuries AD. Convincing evidence for pre-Norse activity, although unsupported by radiocarbon dates, was recovered from Glassknapper's Cave in the form of probable Iron Age pottery, while late Neolithic pottery came from floor deposits in the Wetweather Cave.

Abstract:

The tropical western South Atlantic, which includes a substantial portion of the Brazilian Exclusive Economic Zone, is a region of endemism broadly recognized as being of prime importance for the conservation of the marine biodiversity. The north coast of Brazil, which comprises the states of Amapá, Pará and Maranhão from the mouth of the rio Oiapoque to the mouth of the rio Parnaíba, harbors the largest continuous mangrove in the world, with approximately 8,900 km2. The high discharge of freshwater and continental sediments in the delta of the Amazonas affects the regime of tides, ocean currents, and several oceanographic processes of the north coast, with direct impact on the composition of the biota found in the region. Despite its economic value and intrinsic biological relevance, several aspects of the diversity of the marine and estuarine fishes of the region are poorly known. This situation results mainly from a historical imbalance in terms of the number of studies devoted to increasing the knowledge of the marine biota along the Brazilian coast, such as those dealing with species inventory and taxonomic revisions, which are typically concentrated in the south and southwestern portions of the country. The scientific production focused on marine organisms of the north coast is also imbalanced, and reflects the relatively small number of taxonomists and research groups working on that subject. The insufficient knowledge of the biodiversity of the marine and estuarine fishes of the north coast is an impediment to the implementation of adequate public policies aimed at the management of natural resources in the region. In the long term, that situation is potentially harmful in terms of conservation of a still poorly known biota. A better understanding of the marine fish fauna of the north coast of Brazil will be achieved only through the investment in scientific research and personnel training in systematics and biogeography, coupled with the modernization of the current infrastructure and expansion of scientific collections of the region.

Abstract:

A arborização viária é negligenciada por muitas prefeituras brasileiras, ao não considerarem árvores parte da infraestrutura urbana. Neste contexto, este estudo pretende analisar o planejamento da arborização de ruas da cidade de Maringá, localizada no Norte do Estado do Paraná. Como objetivos específicos tem-se: a) identificar a legislação municipal referente à arborização urbana no período de 1950 a 2022; b) analisar o Plano de Gestão de Arborização Urbana (PGAU) de Maringá, publicado em 2020.Os procedimentos metodológicos compreenderam três linhas de análise: histórico de ocupação urbana; histórico da arborização de ruas; e análise do PGAU, através de pesquisa bibliográfica e documental. Maringá teve seu planejamento da arborização inicialmente realizada pela Companhia de Melhoramentos Norte do Paraná entre 1947 e 1982 e, na sequência, pela Prefeitura Municipal. Conclui-se que o PGAU é um importante documento de gestão de planejamento, elaborado por este município, mas que apresenta algumas deficiências que poderiam ser mais bem trabalhados.

Abstract:

This paper examines 2 potential sources of the radiocarbon offset between human and terrestrial mammal (horse) bones recovered from Norse (∼AD 870–1000) pagan graves in Mývatnssveit, north Iceland. These are the marine and freshwater 14C reservoir effects that may be incorporated into human bones from dietary sources. The size of the marine 14C reservoir effect (MRE) during the Norse period was investigated by measurement of multiple paired samples (terrestrial mammal and marine mollusk shell) at 2 archaeological sites in Mývatnssveit and 1 site on the north Icelandic coast. These produced 3 new δR values for the north coast of Iceland, indicating a δR of 106 ± 10 14C yr at AD 868–985, and of 144 ± 28 14C yr at AD 1280–1400. These values are statistically comparable and give an overall weighted mean δR of 111 ± 10 14C yr.The freshwater reservoir effect was similarly quantified using freshwater fish bones from a site in Mývatnssveit. These show an offset of between 1285 and 1830 14C yr, where the fish are depleted in 14C relative to the terrestrial mammals. This is attributed to the input of geothermally derived CO2 into the groundwater and subsequently into Lake Mývatn. We conclude the following: i) some of the Norse inhabitants of Mývatnssveit incorporated non-terrestrial resources into their diet that may be identified from the stable isotope composition of their bone collagen; ii) the MRE off the north Icelandic coast during the Norse period fits a spatial gradient of wider North Atlantic MRE values with increasing values to the northwest; and iii) it is important to consider the effect that geothermal activity could have on the 14C activity of samples influenced by groundwater at Icelandic archaeological sites.

Abstract:

This study presents the results of a marine geophysical survey performed in the Igaliku fjord in southern Greenland in order to understand the harbour setting of the former Norse settlement Garðar (modern Igaliku). The aims of the survey were (a) to reconstruct the former coastline during the first centuries of the Norse settlement period (c. 11/12th centuries) and (b) to search for archaeological remains on the seabed connected to maritime traffic and trade. In order to approach these goals, we used an integrated marine survey system consisting of a side-scan sonar and a reflection seismic system. The system was designed for lightweight transport, allowing measurements in areas that are logistically difficult to access. The side-scan sonar data revealed no remains of clear archaeological origin. Bathymetric data from seismic seabed reflection and additional Differential GPS height measurements yielded a high-resolution bathymetric map. Based on estimates of Holocene relative sea level change, our bathymetry model was used to reconstruct the shift of the high and low-water line since the early Norse period. The reconstructed coastline shows that a small island, which hosts the ruins of a tentative Norse warehouse at the mouth of the present harbour, was connected to the shore at low tide during the early Norse period. In addition, reflection seismics and side-scan sonar images reveal a sheltered inlet with steep slopes on one side of the island, which may have functioned as a landing bridge used to load ships. We also show that the loss of fertile land due to sea level rise until the end of the Norse settlement was insignificant compared to the available fertile land in the Igaliku fjord and is thus not the reason for the collapse of the colony.

Abstract:

Crinoidea from the Pennsylvanian deposits of the Itaituba Formation, Northern Amazonas Basin. The Itaituba Formation comprises part of the marine section of the Tapajós Group in the Amazonas Basin. This unit mainly comprises Pennsylvanian carbonate deposits associated with various marine invertebrate fossils. In this work, we present new records of crinoids in the Itaituba Formation in the Caltarém quarry, north platform of the Amazonas Basin. There are described and taxonomically identified, two genera of crinoids, through the study of columnals and pluricolumnals, in addition to the interpretation of the depositional environment through the analysis of carbonate microfacies. The identified specimens correspond to the species Cyclocaudex aff. typicus Moore & Jeffords, and to the genus Pentaridica Moore & Jeffords (first record in the Itaituba Formation). The textural, compositional, and paleontological analysis suggests four standard microfacies MPF 09, 10, 16, 23) and two faciological zones (ZF 7 E 8). The bioturbated bioclastic wackestones (MFP 09) and bioclastic wackestones/packstones (MFP 10) microfacies, with fossils of brachiopods, crinoids, echinoids, miliolid and fusulinid foraminifera, trilobites, and bryozoans, characterize an interior shelf environment, with a connection to an open marine circulation (ZF 7). The peloidal wackestones (MFP 16) and mudstones (MFP 23) microfacies, with a fossiliferous assemblage limited to brachiopods, echinoids and miliolid foraminifera, characterize a restricted lagoon environment (ZF 8). Paleontological data and microfacies analysis indicate the development of a lagoon environment with a diverse paleofauna of marine invertebrates in the carbonate platform of the northern bord of the Amazonas Basin, in the Monte Alegre County, during the Pennsylvanian. Keywords: taxonomy, echinoderms, microfacies, paleoenvironment, Pennsylvanian.

[Introduction]: Coastal areas constitute the interface between land and marine environments, connected through multiple natural and socioecological processes that contribute to human well-being. [Objective]: Identify land and marine uses and activities with mutual implications and biophysical processes in the northern region of the Bonaerense Coastal Ecosystem (Argentina), in order to evaluate the degree of compatibility or conflict between these activities, with emphasis on the fishing activity. [Methodology]: The land-sea-land (T-M-T) methodological analysis was applied. Uses and activities (U&A) and biophysical processes of marine and land origin were determined. Interactions between marine-land and biophysical processes T-M-T were identified for further categorization and analysis. [Results]: A total of 121 U&A sea-land-sea (L-S-L) interactions related to fishing were detected. Medium conflicts were mainly caused by competition for space or resources and were associated with the coexistence of U&A (tourism, fishing, and communication activities), both spatially and temporally. Of the total, 68 negative interactions were observed between biophysical processes and U&A L-S-L, which were linked to climatic events and the effects of climate change (variation in sea surface temperature, atmospheric and oceanic circulation, as well as variations in sediment transport and coastal erosion). [Conclusions]: The analysis carried out constitutes an advancement in the study of U&A T-M-T in coastal-marine areas of the Atlantic coast and their interactions, with emphasis on fishing activities, as a contribution to their management with an ecosystemic approach.

En este trabajo reflexionamos sobre las relaciones que se establecen entre la religiosidad popular y el desierto de Atacama en el Norte Grande de Chile. Para ello vemos como ese inmenso territorio que es el desierto es percibido por las elites políticas, militares y eclesiales. Primero como un lugar carente de vida y segundo como fuentes de riquezas sobre todo minerales. La fiesta de La Tirana y su vasto peregrinaje ha provocado la sacralización de algunas de sus partes. Lo que era un no-lugar se transformó en un lugar lleno de sentido. La religiosidad popular es como veremos más adelante una inscripción territorial. En términos metodológicos hemos realizado desde hace más de una década de viajes prolongados a esta fiesta, una observación e interpretación desde el punto de vista de los peregrinos. Largas conversaciones, análisis del cancionero religioso, entre otros, constituyen nuestras fuentes empíricas. Concluimos que gracias al peregrinaje el desierto de ser concebido, como algo vacío, se llena de vida.

Abstract:

The Brazilian spongiofauna is still one of the least known worldwide, and the Northeastern region of Brazil is the one with the greatest recorded diversity. Previous studies on sponges in the Rio Grande do Norte State focused on deeper regions of the Potiguar Basin and oceanic islands, lacking any records from intertidal environments. The present study aimed to investigate the biodiversity of marine sponges from two beaches on the northern coast of Rio Grande do Norte. The specimens were collected in intertidal beachrocks of Baixa Grande and Ponta do Mel beaches (Areia Branca, RN) quarterly between August 2018 and May 2019, using the active search method for 2 hours during low tide. We identified 19 species belonging to the Demospongiae class, four taxa were considered dominant and six were considered rare according to the sampling period. Our study considerably improved the knowledge of the spongiofauna for the Rio Grande do Norte State, with six new taxa occurrences: Placospongia sp., Dysidea robusta, Haliclona (Reniera) manglaris, Haliclona (Reniera) tubifera, Haliclona (Soestella) caerulea and Amorphinopsis atlantica.

La frontera norte del Estado ecuatoriano se ha visto afectada en la última década por los GIA, y un imporante hecho que ocurrió en el sector de Angostura, en enero del 2008, donde las Fuerzas Armadas de Colombia violaron territorio ecuatoriano mientras realizaban operaciones ocultas contra las FARC, en territorio ecuatoriano. El 26 de septiembre del 2016, el presidente de Colombia, Juan Manuel Santos, firmó formalmente los acuerdos de paz de Colombia con las FARC, pero no todos sus integrantes entregaron las armas. Los grupos que no se acogieron a la paz, continuaron realizando actos de terrorismo y secuestro, es decir, realizando Guerra de cuarta generación en territorio ecuatoriano.

Abstract:

The Barra de Tabatinga Formation corresponds to the previous informally named Barra de Tabatinga unit, after a homonymous beach name. These marine terrace deposits occur along the present shoreline in patches between Natal and Barra de Sagi (ca. 80km). The summit of those deposits is about 7.5m above m.s.l. at Natal. They are composed of very friable clayey sandstones and conglomerates, exhibiting more-or-less conspicuous hydrodynamic sedimentary structures. The Touros Formation, after a homonymous town name, corresponds to the previous Tertiary Guamaré Formation, found by Petrobras only in subsurface. These marine terrace deposits extend, frequently as steep sea-cliffs along the present shoreline, between São Bento and Zumbi (ca. 120 km). The summit of these deposits reaches to a maximum of 20m above m.s.l., 2km to the N of Zumbi. Deposits are made-up of medium to coarse-grained sanstones, frequently well-cemented due to partial dissolution of biodetrital components. Hydrodynamic sedimentary structures, and trace fossils of Ophiomorpha nodosa, are very conspicuous. Both marine terraces, recently dated by TL and/or OSL methods, indicated Upper Pleistocene ages, and overlie unconformably the Neogene Barreiras Formation. Finally, as they fulfill all the requirements of the Brazilian Stratigraphic Nomenclature Code, as demonstrated in this paper, two new formations are formally proposed here.

Abstract:

Reserva Biológica do Atol das Rocas is a marine biological reserve located about 250 Km west of Natal - Rio Grande do Norte, Brazil. It has an abundant fauna of visiting or nestíng seabirds. Its 2 islets, around 3 ha each, shelter the largest breeding colonies of Masked Booby Sula dactylatra and Brown Noddy Anous stolidus in Brazil and of Sooty Tern Sterna fuscata for the South Atlantic. Data on biological aspects of the bird species were collected in 1991, 1993 and 1994. Field work included population censuses; mapping of nesting areas, nest building; eggs, chicks and adults biometry and characterization; bird banding and recoveries, and general observations. The results indicate a breeding period seasonality, possible Iinked with climate. Climate also influences the local vegetation. The drier part of the year expanded the nesting habitat of Sterna fuscata and Anous stolidus (namely at Cemitério islet). The abundance and occurrence of fish species (preys) that are important on seabirds' diet.

Abstract:

The hydrographic basins of northern Espírito Santo comprises the systems of Itaúnas and São Mateus rivers. The present work is part of a series of studies on the fish fauna along Espírito Santo’s river basins. Forty-nine geo-referred points in rivers and rivulets of the area were evaluated, 20 in the Itaúnas basin and 28 in São Mateus basin. The environment and the taxonomic composition of the fish fauna were documented at every point, reporting a total of 83 species, including 47 freshwater species and 36 marine, belonging to 35 families and 11 orders. Among the freshwater fish species, the Siluriformes predominated, with 20 species, followed by the Characiformes, with 17 species. The Atlantic forest of northern Espírito Santo, known as “floresta de tabuleiros”, was originally composed of ombrophylous forest as well as swamps, coastal sand dunes, and mangroves. With the suppression of native forests, the region has suffered from desertification, and environmental conditions are similar to the northeastern semiarid region, where the run-off waters are dispersed or intermittent. The loss of environmental quality along river valleys is associated with the need to reestablish riverine aquatic conditions. Exotic species and risks of introductions need further studies in these areas. Rare or endangered species whose distributional range has diminished in response to environmental changes may function as biological indicators. Potentially new species are identified, and regional endemism and distribution patterns for freshwater fishes are discussed.

Abstract:

Abstract Baía Norte (North Bay) in Santa Catarina State is considered a typical coastal bay and is surrounded by a network of Marine Protected Areas. The objectives of this study were to describe the composition of the demersal fish assemblage, identify seasonal and spatial structures on a fine scale and evaluate the role of habitat descriptors and abiotic variables affecting the fish assemblage structure. Seasonal samplings were conducted in 2005, using bottom trawls in six pre-established areas in Baía Norte in summer, fall, winter and spring. Simultaneously with each trawl, environmental data were collected with a multiparameter probe. Temporal and spatial differences in fish abundance were tested by a PERMANOVA. To illustratethe differences detected graphically we ran a canonical analysis of principal coordinates (CAP). The influence of environmental variables on the fish fauna was evaluated using a Distant Based Linear Model (DistLM) with Akaike's information criterion (AIC). A total of 9,888 specimens, distributed in 27 families and 62 species, were collected. Citharichthys spilopterus was the most abundant species. PERMANOVA detected differences for abundance between seasons, areas and interaction among all the factors. The DISTLM selected temperature and pH. The results highlight seasonality as an important factor in the structuring of fish fauna of the study place.

Abstract:

Pode-se afirmar que um dos pontos mais característicos da poética de João Cabral de Melo Neto (1920-1999) é a metalinguagem, e uma metalinguagem não raro associada também a um juízo estético sobre outros escritores e artistas. Um bom exemplo dessa poesia “crítica” cabralina são seus textos sobre a poeta norte-americana Marianne Moore (1887- 1972). No total, são cinco os textos em que Moore e/ou sua obra aparecem como assunto de poesia. Sabendo também que, em João Cabral, esse juízo crítico sobre outros muitas vezes reflete uma visão crítica sobre seu próprio trabalho artístico, este estudo objetiva averiguar certas implicações estéticas estabelecidas nesses poemas de Cabral sobre Marianne Moore.

Abstract:

The coastline is constantly in undergoing change, in terms of its position (retreat) and form. The retreat of coastal cliffs is a physical, dynamic and complex process that is controlled mainly by the geology of the area, strength properties of materials, marine conditions and climatic aspects of the region. This process is directly related to basal erosion, which is basically the mechanical destruction and/or removal of soil particles from the toe of coastal cliffs, caused mainly by wave action. Basal cliff erosion decreases the stability of the slope and may trigger mass movements and coast retreats. The coastal area of Rio Grande do Norte (Brazil) consists predominantly of sandy beaches and cliffs of Barreiras Formation. In this area, the human occupation has been increasing; therefore, it potentiates the probability of occurrence of mass movement. The objective of this study is to analyze the direct influence of basal erosion on stability of typical cliffs of the district of Tibau do Sul / Rio Grande do Norte - Brazil. The results showed that tensions are generated above the basal erosion as notch extension increases.

Abstract:

ABSTRACTPublished marine sediment core records and new information from terrestrial aeolian deposits from the surroundings of Igaliku Fjord, south Greenland, have been used for a tentative reconstruction of multi-decadal to centennial scale changes in the intensity of regional atmospheric circulation since the Medieval Warm Period. The marine data show that aeolian activity over southern Greenland was generally enhanced in the Medieval Warm Period between c. AD 900 and c. AD 1300. The preliminary data from the onshore aeolian deposits suggest that wind activity was strongest after AD 1000, reaching a peak close to AD 1300, after which atmospheric circulation intensity decreased. A comparison with the marine data shows that this decrease coincides with increased advection of Polar Water by the East Greenland Current at the beginning of the Little Ice Age. The aeolian sediment record suggests foehn wind activity displaying multi-decadal oscillations in the range of known north Atlantic climate oscillations. The intensity of erosional processes in south Greenland has previously often been attributed to farming activities initiated after AD 1000 by the Norse who disappeared a few hundred years later. Our findings suggest, however, that erosion in this area is mainly related to marked variations in wind strength.

Evidências relacionadas à pesca entre populações sambaquianas e da cultura taquara-itararé na Baía da Babitonga são muito antigas, pode-se dizer que desde a sua primeira publicação, no século XIX, há menção aos vestígios relacionados à esta prática, já que estes sítios são constituídos majoritariamente por restos de animais obtidos por técnicas de pesca. Somente a partir dos anos de 1990 estudos sistemáticos voltados para os restos faunísticos e com base na Zooarqueologia começam a ser feitos, permitindo avançar no aspecto qualitativo e quantitativos. Estes estudos permitiram conhecer melhor o papel do peixe em relação aos outros recursos marinhos, as preferências entre as espécies capturadas, as inferências sobre os ambientes frequentados e os petrechos utilizados e as relações de práticas pesqueiras entre estas diferentes culturas. Pode-se dizer que foi este viés que dominou os estudos até recentemente quando pesquisa com foco em populações atuais de pescadores artesanais foi desenvolvida tendo em vista compreender melhor as práticas antigas assim como contribuir nas ações de conservação da fauna marinha. Em suma, o presente estudo traz uma síntese sobre os dados disponíveis sobre a pesca na pré-história da Baía da Babitonga afim de obter subsídios para a brilhante iniciativa de criação de uma rede colaborativa de estudos sobre o tema. Abstract: Evidence related to fishing between sambaquian populations and taquara-itararé culture in Babitonga Bay is very old, it can be said that since its first publication in the nineteenth century, there is mention of the traces related to this practice, since these sites are consisting mainly of animal remains obtained by fishing techniques. Only from the 1990s onwards, systematic studies focusing on faunal remains and based on zooarcheology began to be made, allowing the qualitative and quantitative progress to be made. These studies made it possible to better understand the role of fish in relation to other marine resources, the preferences between the species caught, the inferences about the environments frequented and the equipment used as well as the relationships of fishing practices between these different cultures. It can be said that it was this bias that can contribute to the brilliant initiative of creating a collaborative network of studies on the subject as well as to base conservation studies on the marine fauna of Babitonga Bay.

Abstract:

This study evaluates Foraminiferal assemblages and their relation with grain size, calcium carbonate content, organic matter, and mineralogy of sediment samples collected at the sediment-water interface along a transect on the northern continental shelf of Rio Grande do Norte State, Brazil, adjacent to the city of Areia Branca. The sedimentary sequence of this shelf is represented by lithostratigraphic units of a marine regressive sequence dominated by four facies: Siliciclastic sand, Silicibioclastic Sand, carbonate mud, and Biosiliciclastic sand. The carbonate content ranged from 5.83% to 85% and the organic matter content from 1.16% to 27.05%. Mineralogical characters separated the predominant siliciclastic content (37% to 92%) from the bioclastic content (8% to 63%). We have identified 14 species out of 50 species of Foraminifera, associated to particular depths and sediment types as follows: (1)deeper-water sediments in the middle shelf contain Bolivina striatula, Bulimina marginata, Triloculina trigonula, Pyrgo ringens, Textularia gramen (2)the shallowest sediments in the inner shelf contain Ammonia tepida, Buccella peruviana, Miliolinella subrotunda, and Quinqueloculina patagonica, (3)the central parts of the transect, also in the inner shelf, provide habitats for Quinqueloculina lamarckiana, Textularia earlandi, Buliminella elegantissima, Discorbis peruvianus, and Pyrgo nasuta. The distribution of Uvigerina striata and Buccella peruviana is probably related to colder water temperatures and possibly the occurrence of an upwelling phenomenon for the deepest parts of the area rather than the sedimentological features discussed here.

Abstract:

14C age measurements made on samples from three archaeological sites located on North Atlantic coasts were used to investigate the marine reservoir effect (MRE) at c.AD 1000. This is an important period within human cultural and palaeoenvironmental research as it is a time when Norse expansion to the North Atlantic islands occurred, during what appears to be a period of ameliorating climatic conditions. This makes improved chronological precision and accuracy at this time highly desirable. The data indicate a potential latitudinal variation in MRE at c. AD 1000 from a ΔR of-142±16 14C yr at Omey Island (53° 32' N) to 64±13 14C yr at Undir Junkarinsfløtti (61° 51' N). The results are compared with modern assessments of MRE values within the context of oceanographic and climatic regimes that provide a possible driving mechanism for spatial and temporal variation in MRE.

AbstractDuring the Pleistocene, the coastal marine bivalve mollusc Mya arenaria became extinct in northwest Europe. The species remained present in North America. Datings of Mya shells found in northern Denmark and the southern Baltic Sea suggest that repopulation of northwest European coasts already occurred before Columbus’ discovery of America (1492), possibly facilitated by Viking (Norse) settlers at Greenland and northeast North America. In this paper we report on findings of M. arenaria at five locations in the coastal landscape of the Netherlands: polders reclaimed from the Wadden Sea and the former estuaries of Oer-IJ and Old Rhine. The shells from four of these locations also date before 1492 AD.

In addition to that, this kind of research can provide relevant data to improve the capture of these animals, considering their economy and social importance. This study aimed to analyze the food composition of Larimus breviceps specimens from the northern coast of Cabedelo city, evaluating the importance of each food item for their diet. The specimens came from the local artisanal fisheries. In laboratory, the individuals were identified, measured and dissected to remove the stomachs content and then examined. Three different analyzes were performed, percentage by frequency of occurrence, by number and by weight, then the index of relative importance (IRI%) was computed. In total, 30 stomachs were analyzed, 15 distinct food items were identified, the most representative prey were fish fragments, Copepoda, Gammaridae, Decapoda (shrimp), algal fragments and synthetic material. Given the results, the diet of this species becomes more diversified as young individuals reach the adults size, and ingest marine debris which indicates an anthropogenic impact.</p>

ABSTRACT The federal public agencies have prioritized the financing of underground dams as a strategy to decrease water scarcity in rural semiarid regions in Brazil. The objective of this work was to evaluated water quality in underground dams, for agricultural irrigation purposes, in Rio Grande do Norte, Brazil, at the end of the dry season in 2018 and at the end of the rainy season in 2019. The variables with the greatest impact on water quality were identified through multivariate analysis, using the software Statistica 7.0. The results showed that concentrations of variables correlated with salinity and ion toxicity in water of the dams decreased after the rainy season, whereas those correlated with clogging of localized irrigation systems increased. Salinity, sodicity, and/or toxicity in areas of underground dams were correlated with natural mineralization of geological components of soils; however, they also were affected by rainfall with marine hygroscopic nuclei, presence of rural clusters and corrals, and decomposition of organic matter in the damming area. The variables correlated with salinity presented higher effect on the hydrochemical variability of water within these dams in both sampling periods; electrical conductivity and chloride ions were the most significant variables.

Su pensamiento político, expuesto de forma fragmentaria en cientos de cartas, comunicados, discursos, partes de guerra, etc., tiene una matriz antiimperialista que hace pivotar sobre la necesidad de unidad de la “Nacionalidad Latinoamericana” para derrotar al enemigo del Norte. Este es el sentido principal de los dos documentos que se recogen aquí: urgir a los gobernantes latinoamericanos a rechazar la doctrina Monroe, organizarse políticamente, integrarse como comunidad política siguiendo la estela de Simón Bolívar y defender la soberanía e independencia latinoamericana.

Abstract:

In Rio Grande do Sul State, there are four marine shrimp (Litopenaeus vannamei) farms in the municipal districts of São José do Norte and Rio Grande, and other four with previous license for operation. Thus, the present study aimed to identify and characterize areas for marine shrimp farming located in the Southern portion of the Patos Lagoon estuary (32º00'S 52º00'W) by employing the analysis of satellite remote sensing (Landsat TM and ETM+/Google Earth), airborne remote sensing (35mm system ADAR 1000), terrestrial remote sensing (RICOH 500SE), and field expeditions, integrating data in a Geographical Information System (IDRISI Andes). As a result, the enterprises were built on coastal fields or in obliterated dune areas, which are favorable for cultivation. The proximity of possible consuming markets and local labor, relatively good access roads and local technical support also favor the projects. However, there must be caution in terms of changes in the original projects, which could cause environmental impacts and noncompliance of environmental norms, such as the occupation of salt marsh areas. Based on the obtained information, instruments can be created to help inherent legal decision-making to manage the activity for futures enterprises.

Abstract:

Habitat preference and spatial distribution of Guiana dolphins (Sotalia guianensis) in Norte Bay, southern Brazil, was studied from 2001 to 2005. Boat surveys (N = 91) were made to evaluate the spatial distribution of the dolphins. Seven habitat variables were integrated into a geographical information system, and habitat preference was tested using the ‘Neu method’ and a habitat index. The Guiana dolphins did not use all habitat types in the same proportion as were available. Areas used more intensively included, in order of importance: (1) areas with a steep sloping sea-floor; (2) areas further from urban areas; (3) areas further from mangroves; (4) areas near the mouth of the bay; (5) shallow water areas; (6) areas of clayey-silt sediments; and (7) areas close to shore. From 2001 to 2005 there was a shift in spatial distribution and habitat use by the dolphins. The low frequency of use of areas close to urban encroachment and its related impacts to the marine environment raises concern about the coastal habitat destruction. The Guiana dolphin may be considered a habitat specialist, despite its wide latitudinal distribution in the western Atlantic Ocean. The ecological niche of the species may be defined by a narrow strip of shallow coastal waters (mostly < 30 m) bordering the coastline. The shift in the spatial use was probably linked with changes in the abundance of important prey of the species and possibly was caused by the collapse of a fish stock in the study area region. Different habitats may favour different assemblages of prey and consequently different foraging strategies by the dolphins. Human-related habitat alterations throughout the range of this species are likely to affect dolphins' ecology in many ways and, thus, must be evaluated and mitigated to conserve their critical habitats.

Norse and Celtic voyagers are recorded as reaching and settling in Iceland, Greenland and easternmost North America betweenc. AD 750 and 1000, but the date of these events and the homeland of the colonists are subjects of some debate. In this project, the birthplaces of 90 early burials from Iceland were sought using strontium isotope analysis. At least nine, and probably thirteen, of these individuals can be distinguished as migrants to Iceland from other places. In addition, there are clear differences to be seen in the diets of the local Icelandic peoples, ranging from largely terrestrial to largely marine consumption.

Abstract:

This study aimed to assess the presence of heavy metals, specifically Cadmium (Cd), Copper (Cu), Lead (Pb), Magnesium (Mg), Nickel (Ni), and Silver (Ag), in Nasipit Port, Nasipit, Agusan Del Norte, Philippines. The study measured and quantified the concentrations of these heavy metals in various environmental compartments within and around the port area, including water and sediment samples. This study employed an experimental research design to investigate the presence of heavy metals in Nasipit Port. The research utilized DOST's laboratory equipment and did not involve human respondents. The sampling method involved measuring the distance from the ship to collect water and sediment samples. The study ensured informed consent, voluntary participation, and privacy protection for the participants. The results showed that Cadmium, Copper, Lead, and Nickel were not detected, while Magnesium and Silver exceeded the standard limits set by the DENR. The study found no significant difference in heavy metal contamination between areas with and without ships, indicating that the port is still classified as safe for ecological risk assessment. The recommendations emphasize the importance of community engagement, continuous monitoring, and public awareness to protect the marine ecosystem and public health. Finally, future researchers are encouraged to expand the study to include other heavy metals and investigate their bioaccumulation in fish and other marine organisms.

Abstract:

O Geossistema, como método de análise integrado dos sistemas ambientais, surgiu como ferramenta capaz de suprir, em parte, a necessidade humana de compreender e descrever os processos naturais responsáveis pela organização elementar existente em cada paisagem. O estudo em Geossistema, aplicado ao ambiente litorâneo, pode apresentar um nível de análise de maior complexidade, se comparado ao continente, em função da origem dos elementos e processos dinâmicos existentes em suas paisagens peculiares. Este nível de complexidade é percebido ao longo da Planície Costeira do Amapá (PCA), onde a fisiologia da paisagem deriva principalmente de uma dinâmica geológica, geomorfológica e climática de longo e curto período. O presente trabalho teve como objetivo principal a compartimentação da Região Natural do Cabo Norte, em paisagens síntese, através do método geossistêmico proposto por Bertrand (1968). Os resultados alcançados identificaram três Geossistemas (Ambiente de Sedimentação Paleofluvial e Lacustre, Ambiente de Sedimentação Estuarina, Ambiente de Sedimentação Costeiro e Marinho) que posteriormente foram submetidos ao Índice Qualitativo de Sensibilidade Ambiental adaptado de BRASIL (2004). Como produto foram gerados os mapas de compartimentação da paisagem (Geossistemas) e sensibilidade ao impacto de derramamento de óleo na Região Natural do Cabo Norte. Palavras-chave: Geossistema, paisagem, planície, sensibilidade, Cabo Norte. Abstract The geosystem, as a method of integrated environmental systems analysis, emerged as a tool capable of supplying, in part, the human need to understand and describe natural processes responsible for the elementary organisation exists in each landscape. The study on geosystem, applied to the coastal environment, can present a more sophisticated analysis level, compared to the mainland, according to the origin of the elements and dynamic processes in their peculiar landscapes. This level of complexity is realised along the coastal plain of Amapá (PCA), where the landscape mainly derived from the physiology of a geological, geomorphological and climatic dynamics of long and short period. The present work had as main objective the compartmentalisation of the natural region of the North Cape, in landscapes synthesis, through the geosistemic method proposed by Bertrand (1968). The results identified three geosystems (Paleofluvial and Lacustrine Sedimentation environment, Estuarine Sedimentation environment, Coastal Sedimentation and marine environment) which subsequently underwent a qualitative Index of Environmental sensitivity adapted from BRASIL (2004). As product subdivision maps were generated from the landscape (geosystem) and sensitivity to the impact of the oil spill in the region of North Cape. Keywords: geosystem, landscape, plains, sensitivity, North Cape.

Abstract:

En este artículo utilizamos datos de censos nominativos del año 1836 referidos a 25 pueblos localizados a unos 50 km al norte de París y analizamos quién trabajaba y quién no en cada hogar. Centramos nuestra atención en las mujeres jóvenes y en las condiciones por las que entraban en el mercado laboral sin dejar el hogar paterno. Creemos necesario un enfoque de género para abordar los parámetros que estimulaban la entrada al mercado laboral en referencia a la composición del hogar y al nivel de riqueza de los hogares. En el artículo describiremos, en primer lugar, las fuentes que utilizamos. En la segunda parte, estudiaremos los vínculos entre la cualificación de los hijos y la composición de los hogares. Y en la tercera proponemos un modelo para entender y evaluar los parámetros que explican la entrada al mercado laboral. Al parecer, en esta sociedad el ciclo de vida no explica por completo el comportamiento de las mujeres jóvenes. Encontramos diversos factores que las protegen de la temprana incorporación al mercado laboral entre los que destacan: el estatus matrimonial del cabeza de familia y la presencia de un hermano mayor de 16 años (normalmente un varón) Por último, este estudio nos permite plantearnos las razones del subregistro del empleo en mujeres.
