Em tempos sombrios, a produção acadêmica brasileira sobre alfabetização
Authors: Mortatti Maria do Rosario
Published: May 2018

Visando a contribuir para avaliação crítica da qualidade e do impacto científico e social da produção acadêmica brasileira sobre alfabetização, problematiza-se a correlação entre teses/dissertações e artigos sobre o tema, em periódicos avaliados pela CAPES. Destacam-se os seguintes aspectos: apesar de avanços quantitativos, é ainda incipiente a circulação desse conhecimento como “produção qualificada”; apesar da relativa pluralidade de enfoques analíticos decorrentes da característica interdisciplinar do tema, vêm sendo reiterados objetos de estudo e resultados semelhantes, com dispersão do possível impacto social e científico; é necessária definição conjunta de ações para proposição de novos problemas e objetos, discussão de finalidades científicas e sociais, relação com agências financiadoras e políticas públicas, ampliação/fortalecimento de espaços de discussão, veículos e formas de divulgação do conhecimento sobre o tema.

As políticas de alfabetização no Brasil no contexto do ensino fundamental
Authors: Viegas Elis Regina dos Santos , Rebouças Virgília Margarida
Published: May 2018

Este artigo tem como objetivo identificar e analisar as políticas de alfabetização direcionadas aos primeiros anos do ensino fundamental no Brasil. Apresenta-se como suporte de pesquisa o levantamento bibliográfico-documental, tendo como ponto partida o arcabouço normativo-legal promulgado a partir dos anos de 1990. A partir disso, observa-se que as metas traçadas nas instâncias governamentais almejam um tipo de educação a ser ofertada, qual seja, uma educação de qualidade baseada em projeções, o que no nosso entendimento envolve aspectos muito mais complexos, como: acesso as vagas e garantia de permanência; valorização docente; gestão democrática; infraestrutura física e pedagógica; políticas complementares de apoio social; entre outros. Portanto, todas as ações – ampliação do tempo escolar, focalização de faixa etária, formação continuada docente, avaliação, etc. – no sentido de transformar o quadro da alfabetização só serão significativas se, de fato, conseguirem promover efeitos reais na sala de aula.

Spor Toto Süper Lig takımlarının spor iletişimi bağlamında Instagram’ı kullanımı
Authors: AKYAZI Erhan
Published: May 2018

Spor sözcüğünün
etimolojik kökeni incelendiğinde “fiziksel egzersizler içeren oyun” tanımı ile
karşılaşılmaktadır. Bu anlamda bakıldığında sporun M.Ö. 2000’de başladığını
söylemek mümkündür. Bir başka tanıma göre ise spor “Kişisel veya toplu yarışlar
biçiminde yapılan, bazı kurallara göre uygulanan beden hareketlerinin tümü”dür.
Bu tanıma göre sporun M.Ö. 776 yılında olimpiyat oyunları ile başladığını
söylemek mümkündür. Tanım ve tarihten bağımsız olarak spor günümüzde
milyarlarca dolarlık bir endüstri haline gelmiştir. Günümüz çağdaş dünyasında,
spor endüstrisinin yerine getirmesi gereken faaliyetlerden birisi de paydaşları
ile sürekli iletişim halinde olmaktır. Sosyal medya adıyla genelleştirilen pek
çok araç bu görevi hem kolaylaştırmakta, hem de daha etkili yapılmasına imkan
tanımaktadır. Sosyal medya araçları son zamanlarda giderek birbirlerine
benzemekle birlikte,  sunmuş oldukları
özellikler onları ön plana çıkarabilmektedir. Son zamanların en popüler sosyal
medya araçlarından birisi de 2010 yılında kullanıcıları ile buluşan Instagram’dır.
Bilimsel araştırmalar görsel ve işitsel içeriklerin daha dikkat çekici ve daha
akılda kalıcı olduğunu göstermektedir. Dolayısı ile Instagram’ın popülerleşmesi
şaşırtıcı değildir. Bu kapsamda, çalışma spor iletişimi bağlamında spor
kulüplerinin Instagram’ı ne şekilde kullandıklarını araştırmayı
hedeflemektedir. Türkiye Cumhuriyeti Gençlik ve Spor Bakanlığı’na bağlı 61
federasyon bulunmaktadır. Türkiye Futbol Federasyonu'nun Gençlik ve Spor
Bakanlığa bağlı özerk bir yapısı vardır. Türkiye Futbol Federasyonu'na bağlı 13
lig bulunmaktadır. Bu liglerden en üst seviyede olanı ise taraftar sayısının en
 fazla olduğu Spor Toto Süper Ligi’dir.
Her spor kulübü başta taraftarları olmak üzere paydaşları iletişim halinde
olması gerekmektedir. Bu sebeple daha fazla taraftarı olduğu için çalışmanın
örneklemi Spor Toto Süper Ligi bünyesindeki futbol takımlarının Instagram
hesapları olarak belirlenmiştir.

The impact of zero moment of truth on consumer buying decision: An exploratory research in Turkey
Authors: ERTEMEL Adnan Veysel , PEYK Peyvent
Published: May 2018

As a result of technological
improvements, consumer purchase decision process deviates from its traditional
behaviors. Considering the traditional
consumer behavior, process of product purchase decision begins with being
exposed to a stimulus, to various phases, finally to decision phase. Technological
changes enable consumers to have ready access to available rich information
about all types of products immediately after being exposed to a stimulus. At
this stage, a new concept Zero Moment of Truth (ZMOT) plays a crucial role that
accompanies more information seeking activity prior to going to the store. In
this study, theoretical and existing academic literature investigated with a
prior similar research conducted in US and Asia to analyze the results across
different demographic segments, and to compare ZMOT against other MOTs.

Stability of Functional Equations in Dislocated Quasi-Metric Spaces
Authors: Hejmej Beata
Published: May 2018

We present a result on the generalized Hyers-Ulam stability of a functional equation in a single variable for functions that have values in a complete dislocated quasi-metric space. Next, we show how to apply it to prove stability of the Cauchy functional equation and the linear functional equation in two variables, also for functions taking values in a complete dislocated quasimetric space. In this way we generalize some earlier results proved for classical complete metric spaces.

Authors: Anastasova Karina
Published: May 2018

Qualitative indicators are an important element in establishing truth in polygraph examinations. Considering this, a study of the change in the quality of the signal from the photoplethysmograph in subjects who have used nail polish is extremely relevant and requires a comprehensive qualitative study.

The paper uses general scientific and empirical methods of observation and experimentation, and is a comprehensive study of the effects of nail polish on the quality of the photoplethysmograph signal. It is the first time that this type of research has been conducted using a comparative analysis of subjects who did and did not use nail polish.

Osas and Associated Comorbidities - A Retrospective Study
Authors: Elena-Corina Jeler
Published: May 2018

OSAS (obstructive sleep apnoea syndrome) is the most common type of sleep apnoea, characterised by obstruction of the upper airways during sleep, causing the absence or reduction of airflow, although there is respiratory muscular activity. It contributes to the occurrence of multiple complications such as hypertension, obesity, diabetes mellitus, cardiac and cerebral pathology, metabolic damage. The objective of this study was to evaluate the major comorbidities associated with OSAS in a group of 101 clinically diagnosed and polysomnographic patients with OSAS at “Marius Nasta” Institute in Bucharest during 2014-2015. The obtained results revealed a very high prevalence of ENT disorders, hypertension, dyslipidaemia and gastroesophageal reflux. Also, among these patients, there was an increased incidence of rhythm disorders (17.8%), such as RBB, ESSV, FiA, but also of ischaemic heart disease (16.83%).
Methods of Paraclinic Diagnosis of Catecholamine Secreting Tumours, Especially of Pheochromocytoma
Authors: Mitu Florin , Maștaleru Alexandra , Cojocaru Clementina , Roca Mihai , Mitu Ovidiu , Leon-Constantin Maria-Magdalena
Published: May 2018

Catecholamine tumoral syndrome is caused by lesions of the medulosuprarenal cromafin tissue (pheochromocytoma or pheochromocytoblastoma) or of the neural crest (paraganglioma), from the ganglionar cells (ganglioneurinoma or ganglioneuroblastoma) or from the sympathetic nervous cells (sympathogonia – sympathoblastoma and sympathoblasts – neuroblastoma), tumors that excessively secrete cathecolamines (adrenaline and noradrenaline), but also neuropeptides. Indications for testing are associated with the clinical context. Because the pheochromocytoma means a heterogeneous group of secretory tumours, there is no analysis achieving the 100% accuracy. The diagnosis can be established by hormonal dosages for basal determinations and by dynamic tests or through nonspecific tests. Imagistic explorations like computer tomography, abdominal and pelvic MRI can localise the tumour. Plasma and urinary metanephrines dosage are the first intention tests because have a higher accuracy compared to catecholamines or other metabolites. Considering the low prevalence of catecholamine secreting tumours, we considered it necessary to systematise diagnostic possibilities.
The Impact of the ECB’s Quantitative Easing Policy on Capital Flows in the Cesee Region
Authors: Angelovska-Bezhoska Anita , Mitreska Ana , Bojcheva-Terzijan Sultanija
Published: May 2018

This paper attempts to empirically assess the impact of the ECB’s quantitative easing policy on capital flows in the countries of the Central and South Eastern region. Given the tight trade and financial linkages of the region with the euro area, one should expect that the buoyant liquidity provided by the ECB might affect the size of the capital inflows. We test this hypothesis by employing panel estimation on a sample of 14 countries CESEE countries for the 2003-2015 period. Contrary to the expected outcome, the results reveal either negative or insignificant impact of the change in the ECB balance sheet on the different types of capital inflows. The results suggest that the magnitude of the crisis, to which the ECB responded to was immense, hence precluding any significant impact of the monetary easing on capital flows in the region. The inclusion of a dummy in the model, to control for the 2008 crisis confirms the findings from the first specification and also does not change the finding on the ECB quantitative easing impact on the capital flows. The impact of the crisis dummy on capital flows is negative and it holds for almost all types of capital inflows, except for the government debt flows, which is consistent with the countercyclical fiscal policies and rising public debt after the crisis.

In this context, and under the current conditions, where Cyprus is facing a severe drought the last five years, the purpose of this study is basically to estimate the needed crop water requirements for supporting irrigation management and monitoring irrigation on a systematic basis for Cyprus using remote sensing techniques. The use of satellite images supported by ground measurements has provided quite accurate results. Intended purpose of this paper is to estimate the Evapotranspiration (ET) of specific crops which is the basis for irrigation scheduling and establish a procedure for monitoring and managing irrigation water over Cyprus, using remotely sensed data from Landsat TM/ ETM+ and a sound methodology used worldwide, the Surface Energy Balance Algorithm for Land (SEBAL).
Development of Underwater Laser Scaling Adapter
Authors: Bluss Kaspars
Published: May 2018

In this paper the developed laser scaling adapter is presented. The scaling adapter is equipped with a twin laser unit where the two parallel laser beams are projected onto any target giving an exact indication of scale. The body of the laser scaling adapter is made of Teflon, the density of which is approximately two times the water density. The development involved multiple challenges - numerical hydrodynamic calculations for choosing an appropriate shape which would reduce the effects of turbulence, an accurate sealing of the power supply and the laser diodes, and others. The precision is estimated by the partial derivation method. Both experimental and theoretical data conclude the overall precision error to be in the 1% margin. This paper presents the development steps of such an underwater laser scaling adapter for a remotely operated vehicle (ROV).

Authors: Ion Ion V. , Ciocea Gheorghe , Popescu Florin
Published: May 2018

In this work, the reduction of greenhouse gas emission, and the energy saving by integrating solar collectors and photovoltaic panels in a Stirling engine based microcombined cooling, heating and power (mCCHP) system are studied. The mCCHP system consists of a natural gas Stirling CHP and an adsorber chiller. When the thermal outputs of the Stirling CHP and solar collectors are not sufficient to cover the heat demand for domestic hot water (DHW), heating/cooling, an auxiliary heating boiler starts to operate. The energy saving by using solar energy varies from 13.35% in December to 59.62% in April, in the case of solar collectors usage and from 7.47% in December to 28.27% in July, in the case of photovoltaic panels usage. By using solar energy the annual GHG emission decreases by 31.98% and the fuel cost reduction varies from 12.73% in December to 49.78% in June.
Transfer of Metals in Food Chain: An Example with Copper and Lettuce
Authors: Vincevica-Gaile Zane , Klavins Maris
Published: May 2018

Present study investigated the possible transfer of metals in the food chain (from soil to edible plants). The experiment was done with lettuce Lactuca sativa grown in different types of soil contaminated with copper (Cu2+) in various concentrations, with or without addition of humic substances. The highest content of copper was detected in lettuce samples grown in soils with lower levels of organic matter, thus indicating the importance of soil organics in metal transfer routes and accumulation rates in plants. It was found that copper accumulation in lettuce grown in contaminated soils can be significantly reduced by the addition of humic substances.
A obra errante é viagem e estrada

O artigo aborda a trajetória de uma cópia do David de Michelangelo, que veio a se integrar ao acervo do Instituto Ricardo Brennand (Recife/PE), ao final de 2010. Encomendada no ano de 2000 para decorar o jardim de um restaurante em Curitiba, a peça foi considerada um “objeto de mal gosto” e pivô de uma série de questões, até ser leiloada e adquirida pelo instituto pernambucano, passando por uma verdadeira metamorfose e construindo para si outros sentidos. Considerada em sua biografia e a partir das questões que mobilizou, a cópia se revelou um “objeto inquieto”, privilegiado para se discutir outras histórias possíveis da arte, ao considerar os sentidos das obras de arte não fixos em um determinado espaço-tempo, mas instáveis e construídos em suas trajetórias.
José dos Santos Libório (1850-1923), um notável elo de ligação entre os mercados de arte português e brasileiro
Authors: Mariz Vera
Published: May 2018

José dos Santos Libório foi um dos principais agentes do mercado de arte português durante as duas últimas décadas de Oitocentos, tendo sido responsável pela organização de alguns dos mais icónicos leilões do seu tempo. No segundo decénio do século XX mudar-se-ia para o Rio de Janeiro, onde viria a notabilizar-se como um reputado antiquário cujas exposições comerciais atrairiam os principais colecionadores brasileiros. Este artigo constitui a primeira abordagem especificamente focada neste fascinante agente. Como tal, o principal objetivo consiste em analisar a atividade profissional de Libório entre a criação da Empreza Liquidadora em Lisboa no ano de 1886 e a sua bem-sucedida incursão no mercado de arte brasileiro a partir de 1910. A investigação e análise de periódicos da época, bem como de publicações coevas, catálogos de exposições e algum material de arquivo, revelaram-se fundamentais para alcançar o objetivo traçado. No final, concluímos que estamos perante um agente económico absolutamente notável pelo seu dinamismo, perspicácia e arrojo, características que lhe permitiram diferenciar-se tanto em Lisboa como no Rio de Janeiro e, não menos importante, afirmar-se como um extraordinário elo de ligação entre dois mercados de arte.

El objetivo de este artículo es reconstruir la biografía de Modesto Falcón Ozcoidi como el principal impulsor de las Bellas Artes en Salamanca, a través de las fuentes documentales, referidas a su persona, que se encuentran depositadas en el Archivo Histórico Provincial de Salamanca. Durante el trascendental periodo fundacional del Museo Provincial de Bellas Artes de Salamanca, de 1866 a 1876, él fue el primer conservador del mismo, entendiendo el museo como un lugar donde el artista debía completar su formación, realizando sus prácticas, y no sólo como un lugar contemplativo donde formar el gusto del artista. Tras el fracaso de esta propuesta y después de ocho años sin recibir remuneración alguna por parte de la Diputación Provincial, encargada de la gestión del museo, Modesto Falcón concluyó su trabajo en el mismo, presentando su dimisión como conservador del Museo Provincial de Bellas Artes de Salamanca.

Apresentação. Objetos Inquietos
Authors: João Neto Maria , Malta Marize
Published: May 2018

As chaves de leitura tradicionais sobre os objetos (práticos, poéticos, cotidianos, artísticos, banais, excepcionais) consideram-nos na inércia, desenvolvendo-se poucas análises sobre seus movimentos, suas ações no espaço e no tempo, suas atuações no mundo, especialmente no campo da história da arte.  Mas podemos pensar que a condição de imobilidade é uma situação temporária e o destino de muitos objetos é sua errância. Há inúmeros objetos inquietos, como há múltiplos modos de inquietude em objetos.  Alguns, saindo da sua inércia, assumem uma lógica desordenada e imprevisível de atuação, assumindo uma identidade particular.  Existem uns que, frente à sua potência poética em sobressalto, nos deixam atônitos, com a mente agitada, sem condições de nos manter passivos, fazendo-nos ver, ouvir, sentir de maneira incomum.  Outros nos instigam a rever paradigmas, conhecimentos dados e visualidades datadas. Alguns fazem nos movimentar com eles ou pelo menos nos provocam mobilidade, ao circundá-los, penetrá-los, experimentá-los.  Alguns nos incitam a nos movermos por destinos ainda não explorados, fazendo com que nossos corpos empreendam, necessariamente, novas posturas. Certos objetos tiveram como destino várias paragens, reinventando-se a cada lugar ocupado e incidindo sobre a conformação do lugar, como se nunca conseguissem se acomodar em determinada situação. Isso também pode ocorrer nos enquadramentos classificatórios, quando os rótulos não conseguem dar conta da natureza múltipla e ambígua dos objetos inquietos. Sua inquietude também implica se manterem como  enigmas, dificultando-nos decifrar aquilo que guardam e não dizem, que escapam às nossas indagações, ou se manterem como errantes ou metamórficos que, por sua propensão a mudanças constantes, de lugar e de aparência, atrapalham percebê-los em suas variantes.
Pervasive allele-specific regulation on RNA decay in hybrid mice
Authors: Sun Wei , Gao Qingsong , Schaefke Bernhard , Hu Yuhui , Chen Wei
Published: May 2018

Cellular RNA abundance is determined by both RNA transcription and decay. Therefore, change in RNA abundance, which can drive phenotypic diversity between different species, could arise from genetic variants affecting either process. However, previous studies in the evolution of RNA expression have been largely focused on transcription. Here, to globally investigate the effects of cis-regulatory divergence on RNA decay in mammals for the first time, we quantified allele-specific differences in RNA decay rates (ASD) in an F1 hybrid mouse. Out of 8,815 genes with sufficient data, we identified 621 genes exhibiting significant cis-divergence. Systematic analysis of these genes revealed that the genetic variants affecting microRNA binding and RNA secondary structures contribute to the observed divergences. Finally, we demonstrated that although the divergences in RNA abundance were predominantly determined by allelic differences in RNA transcription, most genes with significant ASD did not exhibit significant difference in RNA abundance. For these genes, the apparently compensatory effect between the allelic differences in RNA transcription and ASD suggests that changes in RNA decay could serve as important means to stabilize RNA abundances during mammalian evolution.
Proteomics and C9orf72 neuropathology identify ribosomes as poly-GR/PR interactors driving toxicity

Published: May 2018

Frontotemporal dementia and amyotrophic lateral sclerosis patients with C9orf72 mutation show cytoplasmic poly-GR and poly-PR aggregates. Short poly-(Gly-Arg) and poly-(Pro-Arg) (poly-GR/PR) repeats localizing to the nucleolus are toxic in various model systems, but no interactors have been validated in patients. Here, the neuronal interactomes of cytoplasmic GFP-(GR)149 and nucleolar (PR)175-GFP revealed overlapping RNA-binding proteins, including components of stress granules, nucleoli, and ribosomes. Overexpressing the poly-GR/PR interactors STAU1/2 and YBX1 caused cytoplasmic aggregation of poly-GR/PR in large stress granule–like structures, whereas NPM1 recruited poly-GR into the nucleolus. Poly-PR expression reduced ribosome levels and translation consistent with reduction of synaptic proteins detected by proteomics. Surprisingly, truncated GFP-(GR)53, but not GFP-(GR)149, localized to the nucleolus and reduced ribosome levels and translation similar to poly-PR, suggesting that impaired ribosome biogenesis may be driving the acute toxicity observed in vitro. In patients, only ribosomes and STAU2 co-aggregated with poly-GR/PR. Partial sequestration of ribosomes may chronically impair protein synthesis even in the absence of nucleolar localization and contribute to pathogenesis.

The 5G advent is stimulating research and development of new solutions and tools to serve the Media & Entertainment industry in order to cope with all the demanding requirements for very high volume (downlink and uplink), for service fruition across multiple devices, for anytime and anywhere coverage, for Quality of Service and security. In this paper, we focus on scenarios and requirements to implement orchestrated virtual CDNs in 5G networks used to distribute ultra-high-definition media contents. This work originates from the research activities within the H2020 5GMEDIA project, in which We are designing a solution across the edge Point of Presence (PoP) and core data-centers of an operator network, to allow the distribution of UHD media contents from central production centers to end users. Our vCDN solution can elastically cross various anchor points for fixed and/or mobile broadband services down till personal devices, both fixed and mobile to properly serve users attached to the 5G network. The work reports on results of our initial design phases and focuses on the specific scenarios and requirements in our scope. The implementation of the designed virtual CDN solution powered by the 5G-MEDIA management and orchestration platform is an ongoing task, which – once completed - will allow us to validate the proposed scenarios and service orchestration approaches through the 5G-MEDIA in the project testbeds.

The result of ANOVA One-Way test showed a significant difference in the width of clear zone, colony zone and PER and AER score with p-value < 0,05. This indicates that Actinomycetes isolates contain compounds that can act as inhibitors of protease and amylase enzymes from E.coli ATCC 25922. It is hoped that there will be research about the identification of Actinomycetes species isolates in Bogor Botanical Garden so that later can be cultivated and produced as an antibiotics alternative.

Some Actinomycetes isolates of tin plant (Ficus carica L.) have been obtained, namely T24M, T18, T19, T24, T25, T34, T37, T41 and T43. The aim of this study were to optimize the production of secondary metabolites (antibiotics) and screening antibacterial activity against Methicillin Resistant Staphyllococcus aureus (MRSA) from the Actinomycetes isolate of the tin rhizosphere. The study was performed with test an activity of the culture fluid from Actinomycetes isolate against MRSA by the well method. The result of optimization secondary metabolite production showed that the second day was the best incubation time to harvest antibiotics. The results showed that bacterial isolates of T24M produced antibiotics that could inhibit MRSA growth.

Reindeer Rangifer tarandus fences as a mortality factor for ptarmigan Lagopus spp.
Authors: Bevanger Kjetil , Brøseth Henrik
Published: May 2018

To assess how important reindeer Rangifer tarandus fences are as a mortality factor for ptarmigan Lagopus spp. we collected data during 1991–1994. Our fieldwork covered 12 different sections of reindeer fence (totalling 71.1 km) in the county of Finnmark, northern Norway. The sections consisted of steel wire, steel netting or a combination of these, and ranged in height from 100 to 250 cm. The fieldwork took the form of spring patrols during which dead birds and their remains were searched for along the fences immediately after snow melt. We covered a total of 179.9 km and found 253 collision victims belonging to at least 20 species. Of the 253 victims found, 215 were willow ptarmigan Lagopus lagopus and rock ptarmigan L. mutus; thus these two species comprised 85% of the victims. During the winters of 1992/93 and 1993/94, we carried out experiments with dummy willow ptarmigan which were placed along fence sections and monitored serving as artificial fencestrike victims. Our experiments showed that approximately 64% of the total number of ptarmigan killed by the fences during winter would be detected during spring patrols along the fences. The type and height of the fence had no effect on the ptarmigan collision rate. In contrast, both the fence section and year factor contributed significantly to the observed variation in collision rate. We estimate that on average 1.4 ± 0.5 (SE) ptarmigan are being killed per kilometre of reindeer fence in Finnmark annually, with a greater variation between fence sections than between years.
Energetics of feeding on winter wheat versus pasture grasses: a window of opportunity for winter range expansion in the pink‐footed goose Anser brachyrhynchus
Authors: Therkildsen Ole R. , Madsen Jesper

Traditionally, pink‐footed geese Anser brachyrhynchus wintering in Denmark, the Netherlands and Belgium have used the Danish sites only during mild winters, rapidly moving southwards in case of cold spells. Since the 1980s, an increasing number of geese have remained on the Danish wintering grounds despite cold spells, foraging on pastures and winter wheat Triticum aestivum fields. We compare the daily time and energy budgets and the food quality in the two habitats during winter. Winter wheat fields were increasingly used by the geese as temperatures dropped. At temperatures around 0°C, the geese foraged in both habitats, spending on average 83.8% and 74.9% of the daytime foraging in pastures and winter wheat, respectively. The estimated daily energy expenditure was slightly higher on pastures than on winter wheat fields (1,076 vs 1,057 kJ). The estimated daily food intake determined using the ‘marker substance’ method was 148 and 157 g ash free dry weight (AFDW) in geese feeding on pastures and winter wheat fields, respectively, equivalent to a daily net energy intake of 1,109 kJ and 1,145 kJ. Daily food intake, estimated on the basis of oesophagus contents of collected birds, was 170 g AFDW in pasture feeding geese and varied within 159–229 g AFDW in winter wheat feeding geese. In the mild winter, the protein content in winter wheat and Poa did not differ, whereas in the severe winter the protein content remained high in winter wheat but decreased in Poa. During the winters of 1994–1996, the abdominal profile index, API, in individually neck‐banded geese observed repeatedly, only changed significantly during late January 1996. Neither during cold spells was there any change in API. Since the 1980s, the area covered by winter wheat has increased markedly in Denmark. Because winter wheat represents a reliable and profitable food source even in severe winters, the recent change in agricultural practice has enhanced the development of a new wintering strategy of pink‐footed geese, allowing a northward expansion of their winter range. Potentially, this will increase the crop damage conflict and may lead to further population growth.
Modelling water level influence on habitat choice and food availability for Zostera feeding brent geese Branta bernicla in non‐tidal areas
Authors: Clausen Preben
Published: May 2018

Brent geese Branta bernicla spring fattening around Agerø, Denmark, alternate between feeding on saltmarshes and submerged Zostera beds in Limfjorden. It appeared from field observations that these alternations depended on the water level in Limfjorden. A model was developed to assess the impact of water level fluctuations on the habitat use. A second model was developed to estimate the impact of water level on Zostera availability. The first model was successful in demonstrating that fluctuations in water levels had considerable influence on habitat use by the brent geese, i.e. they fed on Zostera at low water levels and on saltmarshes during high water levels, particularly so in early spring, and that the switch between habitats occurred within a narrow water level span of ca 30 cm. The second model demonstrated that the switch between habitats could be explained by lowered availability of Zostera as water levels increased. By combining the output from the two models, differences between years could partly be explained by differences in Zostera availability in the early spring period (21 March ‐ 25 April), whereas a more complicated situation was detected later in spring (26 April ‐ 31 May). The models presented may be considered as tools in investigations of habitat use and carrying capacity of seagrass beds in non‐tidal areas, where birds' access to feeding areas regularly may be hindered by high water levels.
Are Norwegian lemmingsLemmus lemmusavoided by arcticAlopex lagopusor red foxesVulpes vulpes? A feeding experiment
Authors: Barth Lukas , Angerbjörn Anders , Tannerfeldt Magnus
Published: May 2018

Arctic foxAlopex lagopusand red foxVulpes vulpesare close relatives with similar niche demands in the Holarctic. Where they are sympatric, they compete for territories, dens and food. Scat analyses from Fennoscandia have shown different proportions of lemmings and voles in the diets of the two fox species suggesting food partitioning. However, it was not clear if this was due to different food preferences or distinct habitat use. Since the arctic fox is an endangered species in Fennoscandia, it is important to know whether the superior, north spreading red fox can oust it from the tundra habitat, or if food specialisation may prevent displacement. In a feeding experiment at the Lycksele Zoo in northern Sweden, we compared the food preferences of two arctic and two red foxes. Our results show that the four individuals responded similarly to a variety of food items, and particularly that the two species were not distinct in their food preferences concerning lemmings and voles. However, the foxes had considerable individual predilections. Therefore, in the wild, the unequal proportions of lemmings and voles found in scats may reflect different habitat use for hunting.
