Monitoring wolf populations using howling points combined with sign survey transects
No full textWolves respond to simulated howling, especially during the mating and breeding seasons. Simulated howling points are, therefore, commonly used by many wolf researchers around the world to estimate pack numbers in a given area. A large amount of information is available on various pack breeding
areas in Asturias, the only region in north-western Spain where the Iberian wolf (Canis lupus signatus, Cabrera 1907) is not classed as a game species. Wolf research began there in the early 1980s. We present the results of the latest study on population status, conducted between July and November, 2001. Using sampling transects to detect wolf scat and scratch marks and designated howling and observation points, twenty one (21) wolf packs were
definitely located, with two others considered “likely”. Nineteen (19) packs were detected using howling points (n=314). The results of this study show that simulated howling points and sampling transects are reliable and
inexpensive way of detecting wolf packs

An evaluation of deep learning achieved by students studying environmental science modules using the Wolverhampton Online Learning Framework (WOLF)
No full textReport of a CELT project on supporting students through innovation and researchThe Division of Environmental and Analytical Sciences uses the Wolverhampton Online Learning Framework (WOLF) for part of its module delivery programme at all 3 levels within all Awards. This initiative followed from the mission statement that the University of Wolverhampton is committed to broadening access to the widest range of students capable of succeeding in higher education. It is however difficult to assess the level of success achieved by WOLF-based modules in terms of the student’s true understanding of module concepts, although end-of-module evaluation forms completed by students have allowed some feedback on satisfaction of the way in which modules use WOLF. There has been limited information available on specific learning and teaching issues that might help guide the style of module delivery using the WOLF system. Indeed if WOLF-based modules are intended to be an alternative form of delivery for modules that are delivered by conventional methods, evaluations for the level of true understanding achieved by students (whatever their chosen platform for studying the module) would be very useful information to develop. The research involved canvassing the opinions of students on modules that are committed to the use of WOLF as part of the module delivery. Tracking facilities within the administrator’s role on WOLF gives feedback on the amount of time students spend on WOLF pages. However it is not possible to evaluate the level of learning or understanding that has been achieved by students from tracking statistics alone. There are therefore 3 main aims for this research: 1. To evaluate the level of deep learning achieved by students studying environmental science students who have accessed the modules via WOLF. 2. To study the quality and style of approaches to learning adopted by students that have accessed modules through WOLF. 3. To assess the effectiveness of module delivery by utilising WOLF
Use of satellite images for broad-scale modelling of conservation areas for wolves in the Carpathian Mountains, central Europe
No full textThis study analysed the spatial structure of the Carpathian Mountains, in Central Europe, considering it a unit that extends across national boundaries, and assessing the suitability of areas were wolves could be conserved. Physical characteristics of the area were extracted from NOAA-AVHRR NDVI. A set of 9 images from different periods of the year was used to parameterise the phenological variability of the area. Digital maps of road networks, human settlements and a DEM were integrated in a GIS. Locations of wolf presence
were used to extract “optimal” environmental characteristics that served as reference for estimating the degree of suitability over the whole area. Results show that most of the Carpathian Mountains are highly suitable for the wolf and that highly suitable areas are actually inhabited by the present population of wolf. These are also the area most phenologically stable
Die Anwendung von Mikrosatelliten zum Studium der Sozialstruktur bei Großsäugetieren : am Beispiel von italienischem Wolf und Damwild
No full textScandura M. The use of microsatellites in the study of social structure in large mammals : Italian wolf and fallow deer as case studies. Bielefeld (Germany): Bielefeld University; 2004.The content of the present PhD thesis deals with the application of microsatellite analysis to the study of two species of large mammals, referring to some aspects of their social and mating systems. The Italian wolf (Canis lupus) and the fallow deer (Dama dama) were chosen as case studies, since genetic investigations on their populations result, for different reasons, problematic.
The wolf in Italy is a particularly protected species, recovering throughout the peninsula from the effects of a recent bottleneck. Sampling wolves may not rely on capturing or killing them, therefore an alternative, non-invasive, approach was adopted in my study. Scats, shed hairs and blood drops collected on the snow represented the main source of DNA for the analysis. Methodological cares were necessary to obtain reliable wolf genotypes. A set of ten canine microsatellites was employed to achieve unique multilocus genotypes in the population. Fifty-two individuals were typed in the period 1998 - 2003. In some cases, pack composition was determined, confirming that familiar bonds are at the basis of wolf social units. An unpredictable high local differentiation was found among geographic areas. Early dispersal seem to be common in the population, but its effects on the gene flow are not detectable, at least at my study scale. I proposed that most of this dispersal may be unsuccessful or over long distances. The study population, indeed, seem to have reached a high level of local saturation, with clumped pack territories and high reproductive rates, and thus possibly represents a source, from which wolves disperse toward sink areas.
The second study involves an enclosed population of fallow deer. Lekking is seldom observed in mammals, and among them, it is more common in ungulate species. Fallow deer is one of the most studied lekking ungulate and this particular population is object of long-term researches on male mating strategies. Mature bucks in the population join into leks during the breeding season: a costly strategy, which apparently does not guarantee high direct benefits (fitness). In this study, for the first time, I used a molecular approach to verify the existence of a genetic basis to lek formation. The recourse to microsatellites enabled to overcome the strong limitation due to the extremely monomorphism of the species, documented in several studies. Though the low variability even at microsatellite loci, the hypotheses of kin selection (territorial bucks in a lek are relatives) and of heterozygosity advantage (territorial bucks in a lek have an overall high heterozygosity) were tested and resulted not supported by data. Hence, future studies should be addressed towards phenotypic variation and consider in detail physiological and ecological factors, in order to clarify the reasons why lekking takes place in fallow deer
As populações de estrelas Wolf-Rayet em galáxias starburst de alta metalicidade
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Ciências Físicas e Matemáticas. Programa de Pós-Graduação em FísicaNeste trabalho empregamos diferentes métodos de síntese de populações estelares para investigar as populações estelares de galáxias com formação estelar. Também estudamos como a morfologia e abundância do gás ditam os possíveis cenários de formação estelar -- contínuo ou instantâneo. Estamos particularmente interessados em estudar estrelas de alta massa e técnicas para detectá-las. Este trabalho é dividido em três partes. Na parte I discutimos o código Starburst99 e a nova biblioteca de estrelas de baixa metalicidade que adicionamos ao código. Esta nova biblioteca de baixa metalicidade (Z = ¼ Z#) extendeu o código Starburst99 ao regime de baixa metalicidade e verificamos que os ajustes sintéticos são melhorados pelo uso da nova biblioteca. Na parte II empregamos um código de síntese STARLIGHT, que desenvolvemos para o estudo de uma grande amostra de galáxias Starburst Nuclear e HII. Descobrimos que muitas das propriedades destas galáxias podem ser resumidas e melhor estudadas através do uso do vetor de populações X , cujas componentes representam a contribuição de diferentes elementos da base com idades e metalicidades conhecidas. Combinando componentes com idades semelhantes podemos simplificar ainda mais esta representação, escrevendo: X = (xY, xI, xO); onde xY, xI e xO são as componentes representando respectivamente as populações jovens, intermediárias e velhas. Propriamente combinando os diferentes componentes de idade podemos definir a idade média ponderada pela luz L. Verificamos que esta representação é uma maneira poderosa de descrever as propriedades desta amostra, pois as idades das galáxias descritas por L relacionam-se a várias outras propriedades. Em particular, relacionamos L à largura equivalente de H¸ Wobs(H¸). Encontramos que L atua como um ``relógio natural'' que corretamente descreve o comportamento da diluição da Wobs(H¸) com o tempo. Na parte III deste trabalho investigamos uma amostra de 32 galáxias starburst no ótico e no infra-vermelho para estudar a formação de estrelas massivas no regime de alta-metalicidade. Em particular, tentamos entender se a formação de estrelas Wolf-Rayet é favorecida de alguma forma em sistemas de alta metalicidade. Estudos anteriores encontram galáxias Wolf-Rayet em ambientes de baixa metalicidade e a questão é entender se estamos diante de um efeito de seleção ou diante de uma diferença natural entre os regimes de baixa e alta metalicidade. Estudamos as populações estelares da amostra utilizando tanto o código Starburst99 como o STARLIGHT. Também investigamos as propriedades da saliência Wolf-Rayet (uma clara indicação de estrelas com M > 25 M#) centrada em 4640 angstrons e calculamos o número de estrelas WR de Nitrogênio e de Carbono. Encontramos que grandes concentrações de estrelas WR são preferencialmente encontradas em galáxias muito jovens, indicando que a idade destes sistemas é um fator determinante na detecção destas estrelas
