Full textBåde bytestillgång och väderförhållanden har visat sig påverka häckningsframgången hos kattugglor. I Finland har en effekt av vinterförhållanden hittats på kläckningsdatum och i Ungern finns en påvisad negativ effekt av snötäcke på ungöverlevnaden. I den här studien undersöks effekten av snötäckets djup och långvarighet på kullstorleken och ägg- och ungöverlevnaden hos en kattugglepopulation i Västra Götaland. Eftersom regn har visat sig störa och påverka häckningen, har mängden nederbörd under häckningssäsongen jämförtsmed ägg- och ungöverlevnad. Ingen signifikant effekt på kullstorlek p.g.a. snötäcke hittades. På ägg- och ungöverlevnaden hade snötäcket en negativ effekt efter att andra viktiga faktorer som bytestillgång och andelen oerfarna och unga, häckande honor var kontrollerad. En signifikant positiv korrelation hittades mellan nederbörd och ägg- och ungöverlevnad, men efter att ha kontrollerat för andra viktiga faktorer, som mängden fångade byten, hittades ingen signifikant påverkan av nederbörd. Det fanns också en signifikant korrelation mellan regn och andelen fågel bland byten, där år med mer regn hade en mindre andel fågel i bytesfördelningen, en variabel som vanligtvis är högre under låg sorktillgång. För att ge stöd åt metoden att använda byten funna i holkar som indikatorer på bytestillgång finns en påvisad positiv effekt av den totala mängden funna byten och en negativ effekt av andelen fågel bland byten på ungarnas överlevnad. Resultaten indikerar att chansen för ungöverlevnad kan vara påverkad innan äggen är lagda och att det finns en indirekt positiv påverkan av regn påhäckningsframgång p.g.a. en större tillgång av föredragna byten.

Robots are moving from factories to people's homes taking on the roles of artificial pets, tutors and companions. If we are to have emotionally engaging robots, we must understand how we can design robots that people feel empathy towards. In this work, I explore one design criteria for such robots: implicit life stories or the ability for a robot to experience the world we share, be transformed by that experience and communicate that experience to us. Through the construction of novel robots that can have implicit life-stories, and through human subject studies I show that such robots can evoke empathy. I also show that empathy for robots can impact empathy for other human beings.

Full textENGLISH ABSTRACT: During Holocene times a considerable deposit of barn owl pellet material accumulated in the Hot Pot Cave at De Hoop Nature Reserve on the southern coast of the Western Cape Province, South Africa. An excavation of this accumulation has yielded information on barn owl prey species over the past some two millennia. Four distinct layers were excavated and radiocarbon-dated to AD 381, AD 615, AD 991 and AD 1417. The micromammalian cranial contents of these layers were compared to material from two pellet collections that represent modem bam owl predation at De Hoop (AD 2000). Comparisons were made from three perspectives: (1) physical size measurements of certain cranial parameters, (2) micromammal community species composition and (3) community structure indices, such as the Shannon-Wiener diversity index, Simpson's diversity index and the species equitability index. By extrapolating from known ecological distribution information of the relevant prey species, these data were used to recreate the local climate at the time of the accumulation of the layers. The results were compared to other palaeoclimate models for the region as a test of validity. It was found that the lower two layers of the sequence represented mild conditions with possibly more grass than in recent times, while the upper layers represented cool weather with a possible increase in scrub. AD 381 was found to be somewhat dry and mild, AD 615 to be the wettest level and possibly milder than AD 381, AD 991 to be the coolest of all the levels and dryest of the ancient levels, AD 1417 to be somewhat cool and probably drier than AD 615, but wetter than AD 381, and AD 2000 to be the mildest and dryest of all levels, with the artificial influence of nearby agricultural activities evident.
AFRIKAANSE OPSOMMING: Tydens die Holoseen tydperk het 'n relatief groot hoeveelheid nonnietjie-uil bolusmateriaal versamel in Hot Pot Grot in die De Hoop Natuurreservaat aan die Wes-Kaapse suidkus, Suid- Afrika. Opgrawings van hierdie bolusversameling het waardevolle en insiggewende inligting aandie lig gebring rakende nonnetjie-uil prooi tydens ongeveer die afgelope tweeduisend jaar. Vier defnitiewe lae is opgegrawe en deur radiodatering is die lae se datums vasgestelop 381, 615, 991 en 1417 n.e. Deur gebruik te maak van kraniale kriteria. is die mikrosoogdier inhoud van die opgrawings vergelyk met dié van twee bolusversamelings wat die huidige uilprooi (2000 n.Ci) in De Hoop verteenwoordig. Die vergelykings is op drie maniere getref: (1) fisiese grootternates van sekere kraniale parameters, (2) species-samestelling van die mikrosoogdiergemeenskap en (3) gemeenskap-struktuur indekse nl. die Shannon-Wiener diversiteitsindeks, Simpson se diversiteitsindeks en die species-gelykheid indeks. Deur ekstrapolasie vanaf bekende ekologiese verspreidingsinligting rakende die betrokke species, is hierdie data gebruik om die klimaat van daardie tydperke te herskep op 'n streeksbasis en vergelyk met ander paleoklimaat-modelle om die geldigheid daarvan te beproef. Die resultate het getoon dat die onderste (oudste) twee lae warmer toestande met moontlik meer gras verteenwoordig, terwyl die boonste twee lae koeler weer met moontlik meer bosse verteenwoordig. Daar is verder gevind dat 381 n.e. redelik droog en warm was, 615 n.e. die natste laag en moontlik warmer as 381 n.e., 991 n.e. die koudste van al die lae en droogste van die grot-lae, 1417 n.e. redelik koel en moontlik droëer as 615 n.e., maar natter as 381 n.e., en 2000 n.C. die warmste en droogste van al die lae, met kunsmatige invloed van nabygeleë landbou aktiwiteite.

Full textRoads represent a new source of mortality due to animal-vehicle risk of collision threatening log-term populations’ viability. Risk of road-kill depends on species sensitivity to roads and their specific life-history traits. The risk of road mortality for each species depends on the characteristics of roads and bioecological characteristics of the species. In this study we intend to know the importance of climatic parameters (temperature and precipitation) together with traffic and life history traits and understand the role of drought in barn owl population viability, also affected by road mortality in three scenarios: high mobility, high population density and the combination of previous scenarios (mixed) (Manuscript). For the first objective we correlated the several parameters (climate, traffic and life history traits). We used the most correlated variables to build a predictive mixed model (GLMM) the influence of the same. Using a population model we evaluated barn owl population viability in all three scenarios. Model revealed precipitation, traffic and dispersal have negative relationship with road-kills, although the relationship was not significant. Scenarios showed different results, high mobility scenario showed greater population depletion, more fluctuations over time and greater risk of extinction. High population density scenario showed a more stable population with lower risk of extinction and mixed scenario showed similar results as first scenario. Climate seems to play an indirect role on barn owl road-kills, it may influence prey availability which influences barn owl reproductive success and activity. Also, high mobility scenario showed a greater negative impact on viability of populations which may affect their ability and resilience to other stochastic events. Future research should take in account climate and how it may influence species life cycles and activity periods for a more complete approach of road-kills. Also it is important to make the best mitigation decisions which might include improving prey quality habitat.
As estradas representam uma nova fonte de mortalidade para vida selvagem devido ao risco de colisão com veículos apresentando mais uma ameaça à viabilidade das suas populações. O risco de atropelamento de cada espécie depende das características das estradas e das características bio-ecológicas da espécie. Neste estudo pretendemos conhecer a importância dos parâmetros climáticos (temperatura e precipitação) em conjunto com tráfego e os períodos do ciclo de vida da espécie e perceber o papel da seca na viabilidade populacional de coruja-das-torres afetadas por mortalidade nas estradas em três cenários: mobilidade elevada, elevada densidade populacional e a combinação dos cenários anteriores (misto) (Manuscrito). Para o primeiro objetivo correlacionaram-se os vários parâmetros (clima, tráfego e períodos do ciclo de vida). Usaram-se as variáveis mais correlacionadas para construir um modelo misto preditivo (GLMM) da influência dos mesmos. Através de um modelo populacional avaliou-se a viabilidade populacional nos três cenários. O modelo revelou que a precipitação, tráfego e dispersão têm uma relação negativa com os atropelamentos, embora esta não seja significativa. Os resultados foram diferentes, o cenário de mobilidade elevada resultou numa maior diminuição da população e em maiores flutuações ao longo do tempo apresentando um maior risco de extinção do que os restantes cenários. O cenário de elevada densidade populacional resultou numa maior estabilidade das populações com menor risco de extinção e o cenário misto apresentou resultados semelhantes ao cenário de elevada mobilidade. A precipitação parece apresentar um papel mais indireto na influência dos atropelamentos, influenciando a presença de presas a qual pode determinar o sucesso reprodutivo e a atividade desta espécie. A menor densidade populacional representa um maior risco para a viabilidade populacional e resiliência a outros eventos estocásticos. Estudos futuros deverão ter em conta o clima e o modo como este influencia os períodos de atividade das espécies e a incidência de atropelamentos de modo a tomar as medidas de mitigação mais adequadas que poderão passar pelo melhoramento da qualidade do habitat das presas.
