A fractional models of some partial differential equations and analytical approximate solution arising in mathematical sciences
Authors: Hussein Qays Jasem , Altaie Huda Omran
Published: December 2023

The present paper, a combination of Sumudu Adomian Decomposition approach (STADM)is apply to investigate the analytical solutions for some Fractional Differential Equations(FDEs). The STADM is a new technique using the starting causes. To evaluate the effectiveness and powerful of the suggested technique, several applications  for examples are provided to get analytical or numerical results of  Gas  Dynamics equation, Fornberg - Whitham equation and Klein- Gordon equation. The Caputo sense definition applies to fractional derivatives. In addition, the approaches that were proposed gave convergence series solutions that had components that were simple to determine, and they did so without making use of perturbation or linearization.

АБДУЛЛОҲ СУБАЗМУНИЙ ВА УНИНГ “КАШФ АЛ-ОСОР” АСАРИ
Authors: MURATOV Doniyor
Published: December 2023

Ушбу мақола мовароуннаҳрлик машҳур олим, муҳаддис ва фақиҳ Абдуллоҳ Субазмунийнинг ҳаёти ва илмий меросини ўрганишдан иборат. Олимнинг ҳаёт йўли ҳақида маълумотлар жуда оз. Манбаларда унинг фақиҳ олим бўлгани, сомонийлар даврида фаолият олиб борган ва дарс бергани ҳақида ёзилган бўлсада, улар бир-бирини такрорлайди. Бухорода фаолият олиб борган Абдуллоҳ Субазмуний ҳанафий фақиҳи бўлган. У зот Бухорода Абу Ҳафс Кабир оиласига шогирд ҳисобланиб, ўша ерда фиқҳдан дарс берган ҳамда манбаларда фатволар чиқаргани айтилади. Абдуллоҳ Субазмуний муҳаддис бўлгани сабабидан Ҳижоз, Ироқ, Хуросон юртларига сафар қилиб ўз илмини ошириб қайтган. Сафарлари давомида борган жойларида катта олимлардан дарс олган. Шу билан бирга шогирдлар ҳам орттирган. Мовароуннаҳрда фиқҳ илми ривожида Абдуллоҳ Субазмунийнинг ўрни катта. Чунки манбаларда унинг кўплаб фақиҳ олимлар устозлари қаторида туриши кўрсатиб ўтилган. Натижада муҳаддисликнинг шартларидан бири “ҳадис талабида сафар қилиш” қоидасини ҳам бажарган. Манбаларда унинг бир неча асари бор, дейилган бўлсада, олимнинг икки асари аниқланди: “Кашф ал- осор фи маноқиб Аби Ҳанифа” ва “Муснад Аби Ҳанифа”. “Кашф ал-осор” асарида ҳадислар, маноқиблар, фатволар, биографиялар ва бошқа ривоятларнинг адади ҳақида тўхтаб ўтилган. Мақолада “Кашф ал- осор” асарининг Ўзбекистон Фанлар Академияси Шарқшунослик институтида сақланаётган қўлёзма нусхаси ҳақида ҳам маълумотлар берилган. Шунингдек, Мовароуннаҳрдан чиққан баъзи муҳаддис-ровийлар ҳақида ҳам маълумотлар келган.
ХОЖА МУҲАММАД ПОРСО “ҲАФТОДУ СЕ ФИРҚА” РИСОЛАСИНИНГ ИСЛОМДАГИ ФИРҚАЛАРНИ ЎРГАНИШДАГИ АҲАМИЯТИ
Authors: ISMOILOV Mas’udkhon
Published: December 2023

Мақолада темурийлар даври тарихи, маънавий ҳаётига доир масалалар қаламга олинган. Бу даврда юртимизда яшаган халқларнинг маънавиятида катта аҳамият касб этган Яссавия, Кубравия ва Хожагон-нақшбандия тариқатлари вакилларининг фаолияти ўрганилган. Жумладан, Баҳоуддин Нақшбанд ҳамда унинг султонлари Алоуддин Аттор, Хожа Муҳаммад Порсо, Яъқуб Чархий каби шайхлар ҳаёти ва улар ёзиб қолдирган тасаввуф соҳасидаги асарлар ҳақида маълумот берилган. Хожагон-нақшбандия тариқатининг ёзма меросга айланиши, илмий-назарий жиҳатдан асослаб берилиши, таълимот сифатида шаклланиши биринчи навбатда Хожа Муҳаммад Порсонинг илмий фаолияти, унинг қаламига мансуб асарлар воситасида амалга ошган. Унинг асарлари шариатнинг турли масалаларига, тасаввуф назариясига, хусусан, хожагон-нақшбандия тариқати таълимотига бағишланган. Муҳаммад Порсонинг илмий мероси бугунги кунда ҳам ўз аҳамиятини йўқотган эмас, албатта. Масалан, унинг “Ҳафтоду се фирқа” (“Етмиш уч фирқа”)” рисоласи ақида мавзусидаги бошқа асарлари каби бугунги глобаллашув даврида ақидапараст адашган оқим вакилларига раддиялар беришда илмий асосли кўрсатмалар баён қилинган қимматли манба сифатида муҳимдир. “Ҳафтоду се фирқа” рисоласи ушбу мақоланинг марказида туради. Асар Ислом умматининг етмиш уч фирқага бўлиниб кетиши хабарини берувчи ҳадис билан бошланган ва муаллифга маълум бўлган фирқалар рўйхати келтирилган ҳамда ҳар бир фирқанинг асосий ғояси баён қилинган, кейин уларга аҳли сунна олимларининг раддияси келтирилган.
EXTREMIST MOVEMENTS FORMED UNDER THE INFLUENCE OF THE “MUSLIM BROTHERHOOD” IN EGYPT: “MUSLIM BROTHERHOOD” IN EGYPT: A COMPARATIVE ANALYSIS
Authors: SHERMUKHAMMEDOV Komiljon
Published: December 2023

The article comparatively reveals the interdependence of the following religious-political organizations’ activities, directions, ideas, in particular, “Shabab Muhammad”, “al-Takfir wal-hijra”, “al-Jamaat al-islamiyya”, “al-Jihad” formed under the influence of “Muslim Brotherhood” in Egypt, and “Hizb at-tahrir al-islami” whose activity was observed in the Central Asian region, in particular in Uzbekistan. It shows that the “Muslim Brotherhood” was active not only in Egypt, but also in other countries as part of groups related to the same name or associations that correspond to their direction, but with different names. The article also analyzes the fact that the structure of the Muslim Brotherhood has become a unique model for modern terrorist organizations. It was also stated that the “Muslim Brotherhood” movement served as a basis for the emergence of extremist and terrorist organizations in countries such as Algeria, Sudan, Syria, Kuwait, Lebanon, Tunisia, Jordan, Libya, and Pakistan.

Diversidad cultural y saberes ancestrales en Colombia
Authors: Perilla Granados Juan Sebastián Alejandro , Rojano Hooker Wade Néstor
Published: December 2023

El sistema jurídico colombiano reconoce actualmente la diversidad cultural, desde una perspectiva constitucional que busca garantizar los saberes ancestrales de las comunidades indígenas. Sin embargo, parte de la comunidad indígena Zenú, ubicada en Montes de María del Departamento de Bolívar en Colombia, considera que existe un riesgo de perder su legado cultural en el contexto actual. Por lo tanto, se constituyó la Asociación de Mujeres Indígenas Zenú para que desde el trabajo artesanal se establezca una estrategia para preservar sus saberes ancestrales. Este artículo contextualiza la estrategia, sistematiza su implementación y propone posibilidades de fortalecimiento desde una perspectiva interdisciplinaria. Para tales efectos se emplea un enfoque de investigación sociocrítico, con métodos de investigación cualitativa aplicados a trabajo de campo.

Deficiência física e acessibilidade: avaliação de escolas do interior de Mato Grosso do Sul
Authors: Prado Thaiane de Souza , Martins Barbara Amaral
Published: December 2023

O presente estudo tem como tema a acessibilidade, de modo que objetivou-se avaliar e discutir a acessibilidade física (arquitetônica) das escolas públicas do município de Ladário – Mato Grosso do Sul. Sete escolas de nível fundamental participaram da pesquisa que utilizou o “Protocolo para avaliação de acessibilidade em escolas do ensino fundamental” como instrumento de coleta de dados. Os resultados demonstraram que as escolas estão pouco adaptadas para receber estudantes com deficiência física, visto que foram encontradas barreiras arquitetônicas capazes de impedir ou dificultar o acesso a todos os ambientes das escolas, portanto, apesar de a legislação preconizar que a escola deve ser um ambiente acessível, muito ainda precisa ser feito para que o direito à acessibilidade seja plenamente efetivado.
Fashion law e influencers: de la incredulidad a su integración jurídica
Authors: Lorenzo Luna Marina
Published: December 2023

Los comienzos del fashion law y la figura del influencer presentan una gran sincronía, ya que ambos fueron subestimados y en la actualidad destacan por haber alcanzado un merecido reconocimiento social y jurídico. Además de ello, el sector de la moda fue pionero en arriesgarse con la colaboración de influencers para llegar a un mayor número de potenciales clientes. Por ello, los abogados especializados en esta materia podrán prestar un buen asesoramiento a los que, enfocándose en dicho sector, encuentren una fuente de ingresos y tengan que adaptarse a un nuevo panorama normativo, que les presta una mayor atención, y que aunque no ha terminado de materializarse, les exigirá unas responsabilidades que han de conocer para evitar situaciones que les puedan afectar a nivel legal. Por medio de la reciente Ley 13/2022, de 7 de julio, general de la comunicación audiovisual, se reconoce la relevancia del influencer desde el punto de vista de la inversión publicitaria y el consumo, destacando del citado cuerpo normativo la previsión legal de efectos tributarios destinada a evitar migraciones económicas a países de carga impositiva leve, el establecimiento de un registro estatal de prestadores de estos servicios, el fomento de códigos de conducta, la prohibición de publicidad encubierta, la obligatoriedad de identificar las comunicaciones comerciales de forma clara y un amplio catálogo de infracciones y sanciones que pueden llegar a los 600.000 euros. Sin embargo, su entrada en vigor no ha sido completa en relación con algunos de los artículos que dan respuesta a muchos de los interrogantes motivadores de la misma, por lo que habrá que esperar a su desarrollo reglamentario para valorar su efectividad. Por otro lado, dicho reconocimiento les ha de permitir reivindicar una protección mayor en el desempeño de su actividad frente a conductas delictivas por parte de haters o seguidores, ya que pese a encontrar una previsión punitiva en nuestro Código Penal, no es efectiva en su aplicabilidad, debido a la dificultad de identificar o localizar a la persona que se escuda en la cuenta de una red social para desacreditar o dañar al influencer.
Socio-economic factors affecting access to basic formal education among the nomadic pastoralists: A case study of the Samburu
Authors: Lanyasunya Andrew Ropilo
Published: December 2023

The study examines the socio-economic factors influencing access to basic formal education among the Samburu nomadic pastoralists. To facilitate the data collection, Samburu District was stratified into three clusters – Highland-Rural, Lowland-Rural and Urban. Multi-stage and random sampling were used to select from each cluster, one division, one location, one sub-location and then 200 household heads from all the villages in the sub-location. That is moving from the division down to the villages using random sampling. Data were collected and analysed using Excel and SPSS computer packages and further presented using descriptive and inferential statistics. The specific tools used were frequencies and cross-tabulations. There have been policy intentions to improve the accessibility of the nomadic pastoral communities to basic formal education. What has been lacking is the effective implementation of search policies. Government policies need to be driven. This is because if the future of education in Kenya looks bleak as foreseen, what hope will be there for the already disadvantaged people like the nomadic pastoralists?

Çalışma alanına ait oluşturulan hassasiyet parametreleri ve değerlendirme puanı ile alana özgü hassasiyet ölçeği oluşturulmuştur. Su kaynaklarının kalitesini etkileyen faaliyetlere ait puanların, hassasiyet ölçeğinde değerlendirme sonuçları CBS programına aktarılarak, hassasiyet haritası oluşturulmuştur. Bu çalışmada kullanılan metodoloji, su kaynaklarını koruma geliştirme, kentsel-kırsal kalkınma ve göl havzası planlaması gibi çeşitli planlama programlarında yol gösterici olacağı düşünülmektedir.
A fogyatékosügyi mozgalom részvétele a szakpolitikákban 1998 óta Magyarországon
Authors: Petri Gábor , Hruskó Erika
Published: December 2023

A fogyatékos emberek társadalmi mozgalma történetileg befolyásolta a liberális demokráciák fejlődését. A fogyatékossággal élő embereket érintő progresszív szakpolitikai változások a fogyatékosügyi mozgalom nyomására történtek. Ugyanakkor nem világos, hogy a civil érdekvédelmi térnek az erodálódó demokráciákban tapasztalható zsugorodása mennyiben érinti a fogyatékosügyi mozgalmat. Tanulmányunk a hazai fogyatékosügyi mozgalom 1998 óta eltelt időszakát vizsgálja a szakpolitikai bevonódás szintjeire és az érdekvédelmi lehetőségek változására fókuszálva. Tapasztalt mozgalmi szereplőkkel készült interjúkra (15) építve, és szakpolitikai dokumentumok vizsgálatával megállapítható, hogy a hazai fogyatékosügyi mozgalom bevonódása jelentősen romlott a 2010-es évek kezdete óta. A konzultációs platformok kiüresedtek, a kormányzati reakciótól tartva a szervezetek rendszeresen öncenzúrát gyakorolnak a kommunikációjukban, és kerülik a kormányzat kritikáját. A mozgalom széttöredezett. A fogyatékossággal élők igényeinek emberi jogi keretezése egyre kevésbé preferált kormányzati oldalról, az emberi jogokkal szembeni mozgalmi hozzáállás apatikus. Szűkült a média és a független emberi jogi intézmények elérése is.
Visuomotor feedback tuning in the absence of visual error information
Authors: Franklin Sae , Franklin David W.
Published: December 2023

Large increases in visuomotor feedback gains occur during initial adaptation to novel dynamics, which we propose are due to increased internal model uncertainty. That is, large errors indicate increased uncertainty in our prediction of the environment, increasing feedback gains and co-contraction as a coping mechanism. Our previous work showed distinct patterns of visuomotor feedback gains during abrupt or gradual adaptation to a force field, suggesting two complementary processes: reactive feedback gains increasing with internal model uncertainty and the gradual learning of predictive feedback gains tuned to the environment. Here we further investigate what drives these changes visuomotor feedback gains in learning, by separating the effects of internal model uncertainty from visual error signal through removal of visual error information. Removing visual error information suppresses the visuomotor feedback gains in all conditions, but the pattern of modulation throughout adaptation is unaffected. Moreover, we find increased muscle co-contraction in both abrupt and gradual adaptation protocols, demonstrating that visuomotor feedback responses are independent from the level of co-contraction. Our result suggests that visual feedback benefits motor adaptation tasks through higher visuomotor feedback gains, but when it is not available participants adapt at a similar rate through increased co-contraction. We have demonstrated a direct connection between learning and predictive visuomotor feedback gains, independent from visual error signals. This further supports our hypothesis that internal model uncertainty drives initial increases in feedback gains.
A questão dos enterramentos em urna na Idade do Ferro do Sul de Portugal: uma revisão integrada
Authors: Gomes Francisco B.
Published: December 2023

A prática dos enterramentos em urna mereceu um relativo interesse ao longo da história da investigação sobre a Idade do Ferro do Sul de Portugal, tendo desempenhado um papel na construção de modelos histórico-culturais onde a difusão démica e cultural assumia um papel substancial. Apesar das críticas que esses modelos receberam e das nuances que se foram introduzindo na interpretação da sequência histórica sidérica do Sul português, esta modalidade funerária não foi objecto de nenhuma revisão crítica sistemática. Os dados hoje disponíveis permitem contudo revisitá-la numa óptica de longa duração, explorando as relações entre os enterramentos em urna precoces, da I Idade do Ferro, e os mais tardios, da segunda metade do I milénio a.n.e.. De igual modo, o incremento dos dados disponíveis permite hoje repensar e matizar as dinâmicas culturais subjacentes à difusão da prática do enterramento em urna, desenhando um panorama mais complexo e de natureza multicultural.
Os bifaces da estação paleolítica do Casal do Azemel (Leiria, Portugal): uma (re)interpretação
Authors: Ferreira Carlos , Cunha-Ribeiro João Pedro , Méndez-Quintas Eduardo
Published: December 2023

Entre os vestígios materiais do tecno-complexo Acheulense, os bifaces são recorrentemente referenciados como os seus produtos mais icónicos. Sendo inegável a sua relevância no reportório comportamental dos grupos responsáveis pela sua elaboração, ao longo das últimas décadas têm sido alvo de múltiplas abordagens, suscitando, amiúde, diferentes perspetivas. No ocidente europeu, uma das maiores coleções deste tipo de utensílios é proveniente da jazida do Casal do Azemel, conjunto esse que, entre outros aspetos, se caracteriza pelo predomínio de exemplares com uma hierarquização morfológica (volumetria plano-convexa) e tecnológica (configuração sequencial). Alternativamente à proposta que enquadrava a conceptualização da grande maioria dos artefactos na lógica das peças bifaciais suportes de utensílio (Cunha-Ribeiro 1999), argumenta-se que os particularismos em que se baseara essa perspetiva decorrem do tipo de suporte preferencialmente empregue e do mental template inerente à produção destes artefactos, propondo-se que correspondem a peças bifaciais utensílios, como é a norma no Acheulense peninsular.
Inequalities in Online Representation: Who Follows Their Own Member of Congress on Twitter?
Authors: McCabe Stefan , Green Jon , Goel Pranav , Lazer David
Published: December 2023

Members of Congress increasingly rely on social media to communicate with their constituents and other members of the public in real time. However, despite their increased use, little is known about the composition of members' audiences in these online spaces. We address these questions using a panel of Twitter users linked to their congressional district of residence through administrative data. We provide evidence that Twitter users who followed their own representative in the 115th, 116th, and 117th Congresses were generally older and more partisan, and live in wealthier areas of those districts, compared to those who did not. We further find that shared partisanship and shared membership in historically marginalized groups are associated with an increased probability of a constituent following their congressional representative. These results suggest that the efficiency of communication offered by social media reproduces, rather than alters, patterns of political polarization and class inequalities in representation observed offline.
Geo-environmental influences on breeding parameters of the Eurasian Kestrel (Falco tinnunculus) in the Western Palaearctic
Authors: Carrillo J. , González-Dávila E.
Published: December 2023

Geographic location largely determines environmental factors such as photoperiod and primary productivity.Breeding effort in birds may reflect different responses to these geographic- related conditions. We studied geographic variation in mean laying date (LD) and mean clutch size (CS) of the Eurasian Kestrel (Falco tinnunculus) in relation to photoperiod, seasonality of resources, temperature and rainfall during the previous winter and breeding season. We assumed that actual evapotranspiration (AE) varies in direct proportion to primary plant production and food resources. Using published data on 23 Western Palaearctic regions (28–65° N) we found that variation in LD was related to photoperiod. Also, Kestrels bred earlier where winter and spring temperatures were higher, spring rainfall was lower and winter AE was higher. The variables that most affected CS were nest type (box/natural), winter AE and spring temperature. CS was directly related to the ratio between spring and winterAE. Moreover,CS was unrelated with spring AE but inversely related to winterAE. The effect of scarce resources (low AE) during the previous winter on CS supports Ashmole’s hypothesis (Ashmole 1961). The data available are not sufficient to verify the influence of density of breeding adults on CS.
Ranging behaviour of a juvenile Bearded Vulture (Gypaetus barbatus meridionalis) in South Africa revealed by GPS satellite telemetry

Published: December 2023

A second-year Bearded Vulture was equipped with a GPS transmitter and located on average 10 times a day from 6 September 2007 to 22 June 2008. During this period, the individual ranged in an area of ca. 38,500 km2 across the mountainous regions of Lesotho and the north-eastern Cape province of South Africa, thus covering on average 66 km/day, mainly in areas covered by scrubland and herbaceous vegetation. Three different activity areas with a temporal overlap of locations within them were observed. The ranging behaviour could be explained by two non-exclusive alternative hypotheses: food searching and territory exploration. The information provided here may serve to identify potential threats for the species, such as poisoning, collision with power lines, food scarcity and persecution.

We studied the effects of habitat loss, fragmentation and their interaction on the persis-tence of Capercaillie lekking areas at three study areas in Finland. We inspected a total of 381 leks twice with an interval of 10–30 years, and classified them as persisting versus ceased leks. We attempted to explain the persistence of Capercaillie leks with forest cover and fine-grain fragmentation at two spatial scales (within 1,000 m and 3,000 m from the leks) by using satellite-image based forest-inventory data. We statistically removed the effect of forest cover from the measure of fragmentation, and used information-theoreti-cal model selection to evaluate a set of logistic regression analyses. Fine-grain forest frag-mentation had a positive effect on lek persistence. Forest cover positively affected lek per-sistence only when considering the landscapes surrounding the leks (within 3,000 m radius). In addition, we found a significant negative interaction between forest cover and fragmentation. Under conditions of low forest cover, patch configuration may become in-creasingly important for the persistence of lekking areas. According to our results, the most effective management strategies for Capercaillie lekking areas include maximizing the amount of forest around the lekking areas, and encouraging mosaic-like variability of the forest.
Nest predation versus resources in a Neotropical passerine: constraints of the food limitation hypothesis
Authors: Dias R. I. , Macedo R. H.
Published: December 2023

Food limitation is one explanation for differences in life-history traits, such as clutch size or nestling mortality, between tropical and temperate birds. Also predation has been con-sidered one of the major factors shaping life-histories. We found mixed support for the food-limitation hypothesis when we experimentally manipulated food abundance and evaluated subsequent effects on breeding and behavioural parameters of the Blue-black Grassquit (Volatinia jacarina). Food-provisioned males increased territorial disputes and received more female visits, and a higher proportion of supplemented pairs produced more eggs and had faster growth rates in their broods compared to non-provisioned pairs. However, egg laying was delayed in the fed group. Unexpectedly, predation in the food-provisioned group was twice that of the control group. We presume that nest detection by predators increased due to higher nest attentiveness in food-provisioned nests. Food availability constitutes a proximate mechanism resulting in changes in behaviours and breeding parameters, but nest predation may be the prevailing selective pressure.
Habitat associations of old forest bird species in managed boreal forests characterized by forest inventory data
Authors: Jokimäki J. , Solonen T.
Published: December 2023

Conservation areas are important for many species associated with old forests, but most individuals still occur in commercially-used forest landscapes. We conducted three-visit 2 breeding bird surveys in a total of 37 study squares of 1 km , and used National Forest In- ventory data to evaluate habitat associations of birds linked with old forests in three geo- graphical regions: southern, eastern and northern Finland. All study squares were located within managed forests. Out of the total of 23 pre-selected old-forest species, 12 were re- corded in the study squares of all three study regions; the number of species varied be- tween 16 and 21 among the regions. The total abundance did not significantly vary among the regions, but the abundances of many single species varied significantly among the re- gions. Forest-patch size was the single most important factor, positively affecting the abundance of most of the species considered. Development class affected most species in the south and east, and species associated with mature and old forest stands in general. Tree height and stand age were included into the models more often than tree species and diameter. In general, forest patch size, developmental class, age and tree height were among the most important factors in explaining the abundance of old-forest bird species in commercially-used forests. These stand characteristics appeared particularly important for resident species and cavity nesters. Our results indicate that the responses of old-forest bird species to environmental variation in managed, forested landscapes are individualis- tic, and different factors may affect them in different regions. Variables included in the patch-level forest-inventory data well explained abundance variation of species associ- ated with old forests. Our results underscore the importance of integrating national forest- inventory and bird-survey data to obtain information about species habitat requirements and forest-sector related information about the effects of forestry on birds.
Predicting the sex of the Sedge Warbler (Acrocephalus schoenobaenus) by discriminant analysis
Authors: Wojczulanis K. , Jakubas D.
Published: December 2023

Sexual size dimorphism was examined in 273 immature Sedge Warblers (Acrocephalus schoenobaenus) caught in northern Poland during autumn migration in 2008 and 2009. Each individual was measured (wing, tail, head to bill, bill length, bill width, bill height, two measurements of tarsus width and hind claw length) and a blood sample was taken for molecular sexing. A forward stepwise discriminant function analysis was used and three discriminant functions were proposed for sexing Sedge Warblers. The first function, ap-plied to the nine measurements, identified wing and bill length as the best measurements for sexing and correctly classified 82% of individuals. The second and third functions, ap-plied to only wing length and tail length, identified the former as the best single measure-ment, and these two correctly classified 83% and 82% individuals, respectively. These functions may be used as a tool for sexing Sedge Warblers when blood sampling is impos-sible, such as in historical ringing records. However, the functions may be valid only for young birds in north and central Europe measured by experienced ringers.

Migration and staging patterns of the Red-throated (Anthus cervinus) and Tree Pipits (Anthus trivialis) at the migratory bottleneck of Eilat, Israel
Authors: Zduniak P. , Yosef R.
Published: December 2023

We studied the migration patterns of Red-throated (Anthus cervinus) and Tree Pipits (A. trivialis) ringed during 25 years at Eilat, Israel. The number of migrants was four times greater in spring than in autumn for the Tree Pipit but was similar for the Red-throated Pipit. Stop-over during the migration seasons was also different. Both young and old Red-throated Pipits used Eilat as a stop-over site at similar intensity during both seasons. How-ever, most of the Tree Pipits in autumn were juveniles, but young and old individuals were almost equally abundant in spring. In both species, body-condition index was higher in autumn than in spring and was not related to the age of the birds. This finding illustrates differences in body condition before and after the crossing of the Saharo-Arabian desert belt.
The effects of anthropogenic and natural disturbances on breeding birds of managed Scots pine forests in northern Poland
Authors: Zmihorski Michal
Published: December 2023

Anthropogenic disturbance of habitats associated with clear-cut harvesting has replaced natural disturbances, such as wildfire and wind-throw, as initiators of succession in most European forests. Recently, however, forest management has begun to adopt techniques that better mimic natural disturbances, following the documentation of the negative ef-fects of forestry activities, but less information exists on the relative similarity between man-caused and natural disturbances. This study aimed at comparing the bird faunas of windstorm, clear-cut and closed-forest areas in northern Poland. Following the two dis-turbances, species inhabiting open areas and edge habitats increased (e.g., Yellow-hammer Emberiza citrinella and Woodlark Lullula arborea) while closed-forest special-ists decreased (Wood Warbler Phylloscopus sibilatrix, Crested Tit Parus cristatus and Goldcrest Regulus regulus). Community density, rarefied diversity and estimated species richness were higher in the disturbed than in the intact, closed-canopy forests. The spe-cies-specific responses to windstorm and clear-cutting were positively correlated, i.e., a given species that increased in response to one disturbance regime also increased in re-sponse to the other. This finding indicates that man-made disturbances, such as logging, may act as substitutes for natural disturbances for some species.
Diet of the Montagu's Harrier Circus pygargus nesting in natural habitat in Eastern Spain

Published: December 2023

We describe the diet of the Montagu's Harrier (Circus pygargus) population breeding in inland Castellón province (eastern Spain), which exhibits among the highest breeding productivity of European populations of this species. We assessed diet using pellets col-lected at nests at the end of the breeding season. We recorded the minimum number of items in every pellet for six prey classes (lizards, passerines, small mammals, cole-opterans, orthopterans and other insects). We also analyzed between-year relationships in diet diversity and breeding output at the nest level. The most frequently eaten prey were insects, particularly large orthopterans of the family Acrididae. Passerines were also abundant in the diet and contributed more than 50% of the consumed biomass. We found no significant between-year relationship in breeding output and diet diversity at the nest level. Further studies on prey availability in different habitat types would be needed in or-der to understand how land-use changes affect the Montagu's Harrier population.
Prey diversity is affected by climate and differs between age classes in the Red-backed Shrike (Lanius collurio)
Authors: Pedersen Lykke , Geertsma Marten , Tottrup Anders P.
Published: December 2023

When breeding, food availability is essential for optimal reproductive output and is po-tentially one of the main factors limiting breeding success, especially in single brooded long-distance migratory birds. In this study, we examined the diet (as a measure of prey availability) of two Red-backed Shrike (Lanius collurio) populations in Denmark, based on more than 11,000 prey items covering seven years. We found a negative correlation be-tween prey diversity and temperature, indicating that Red-backed Shrikes feed on pre-ferred prey items in warmer summers (low diversity) while forced to feed on a larger vari-ety of species in colder summers. Adults had a more diverse diet and generally fed on smaller prey items than did young birds. Thus, age-and environment-related differences must be taken into account when describing the diet of the Red-backed Shrike. Direct nest observations produced different results for diet composition than did nest and pellet samples, underlining the importance of using different methods in diet assessments. De-tailed knowledge on limiting factors on the breeding grounds, such as food availability, is crucial for mitigating population declines of vulnerable species, such as the Red-backed Shrike.
Red-backed Shrikes (Lanius collurio) adjust the mobbing intensity, but not mobbing frequency, by assessing the potential threat to themselves from different predators
Authors: Strnad Martin , Nemec Michal , Vesely Petr , Fuchs Roman
Published: December 2023

We studied the ability of Red-backed Shrikes to adjust their nest defence to the potential threat posed to defending adults and their nests. We presented mounts of two raptor spe-cies which prey on adult birds (Eurasian Sparrowhawk, Common Kestrel; differing in the proportion of adult passerines in their diets), and two species of nest predators (Common Magpie, Eurasian Jay; differing in the proportion of bird eggs and nestlings in their diets). A mounted Feral Pigeon was used as a control. Shrikes regularly mobbed the Sparrow-hawk, Kestrel and Jay, but not Magpie or Pigeon. The mobbing frequency, in terms of the number of mobbing events per 20 min, did not differ among the three regularly-mobbed predators. If shrikes tried to chase the predator away, they did not adjust the mobbing fre-quency to the level of potential threat to the nest. The proportion of mobbing events result-ing in physical contact (mobbing intensity) declined from the most mobbed species, Jay to the Kestrel, to the Sparrowhawk, which was considered most dangerous to adult shirkes. The Red-backed Shrikes appeared to adjusted their mobbing intensity by assessing the potential threat to themselves. Our results show the importance of a differentiation be-tween mobbing intensity and mobbing frequency in the study of nest-defence behaviour.
Mirrored sequences of colonisation and abandonment by pairs of Golden Eagles Aquila chrysaetos
Authors: Watson Adam , Rae Stuart , Payne Sandy
Published: December 2023

We report colonisation by extra breeding pairs of Golden Eagles, and subsequent abandonments, in part of northeast Scotland during 1895-1985. Thenumber of pairs rose from three in 1895-1937 to eight by 1948, and then fell to four during 1959-71 in reverse of the colonisation sequence. This fits the concept of hierarchic quality of habitat used, or of bird quality. Possible mechanisms to explain this are discussed.

Published: December 2023

The article examines the effects of weather, temporal factors and distance to coast on the flight altitude of migrating waterbirds in Western Estonia. A laser range finder and marine surveillance radar were used to measure flight altitudes. Visible effects on avian flight altitude due to weather conditions such as wind conditions, visibility and cloud cover were identified. Tailwinds were found to be associated with elevated flight altitude, while reductions in altitude were reportedly due to high wind speed. It was noted that behavioural and physical adaptations to the environment also helped in specific flight altitude selection.
The origin of Blackcaps Sylvia atricapilla wintering on the British Isles
Authors: Kopiec Katarzyna , Ozarowska Agnieszka
Published: December 2023

A migration route leading central European breeder Blackcaps to their winter quarters in Britain and Ireland was discovered in the 1960s. This phenomenon, representing a rapid evolutionary change of migratory behavior, can be explained by a shift in migration course towards the west and north-west (as opposed to the standard south-west direction) or reverse migration. These hypotheses were evaluated by analyzing the recoveries of Blackcaps either ringed or recovered on the British Isles. Blackcaps arriving in the British Isles from Scandinavia had been ringed over two weeks later than had been birds arriving from Central Western Europe, while no significant difference was found in the recovery dates of birds from these regions. Moreover, birds ringed in Scandinavia were recovered significantly later on the British Isles than in the continental Europe. This finding suggests that two populations migrate through Scandinavia: the local breeding population (migrating towards the south) and another with an unknown origin (possibly Central European, heading towards the north and west). Thus, some of the Blackcaps ringed in Utsira on the Norwegian west coast, and ending up to the British Isles, might be of Central European origin.
