The Boreal Owl
Widespread in North American forest regions including the Rocky Mountains, the Boreal Owl (Aegolius funereus) was once the most numerous predatory bird in Eurasian boreal forests. Synthesising the results of unique long-term studies of Boreal Owls, this book explores hunting modes, habitats and foods, prey interactions, mating and parental care, reproduction, dispersal, survival and mortality, population regulation and conservation in boreal forests. Providing a detailed introduction to the species, the authors study the complex interactions of Boreal Owls with their prey species. They examine the inter-sexual tug-of-war over parental care, and the behavioural and demographic adaptations to environmental conditions that predictably and markedly fluctuate both seasonally and multi-annually. They also question whether Boreal Owls are able to time their reproductive effort to maximise lifetime reproductive success. Discussing the effect of modern forestry practices on owl populations, the book also examines how Boreal Owls could be managed to sustain viable populations.
Ecology and Conservation of Owls
Owls in Australia are difficult to find and study, so comparatively little is known about their biology. Even less is known about the status, taxonomy, and biology of those species and sub-species living in tropical and subtropical environments and on islands. Many island species and subspecies are at risk, some have already been lost. Ecology and Conservation of Owls includes sections on population ecology, distribution, habitat and diet, conservation and management, and voice structure and taxonomy. It contains a number of review chapters that bring together findings from a wide range of previous research, including recent developments in owl taxonomy and systematics, and studies of population limitation in northern hemisphere owls. The chapters in this book derive from papers presented at the Owls 2000 conference held in Canberra, Australia, which was third in a series of international meetings on owls.
Kiira Korpi
Finnish figure skater Kiira Korpi's career included triumphal championships and bitter disappointments. Trained from early childhood in a sport that demands uncompromising self-discipline and unrelenting work, her "fight until you make it" attitude brought her success and fame--and an insidious performance anxiety. Mental and physical burnout forced her retirement in 2015. With interviews and quotes from family, friends, coaches and competitors, Korpi's candid memoir describes the making and eventual undoing of a champion, reveals a darker side to the "ice princess" image of women's figure skating and advocates a more holistic, athlete-centered model of training.

Stream Processor Architecture
Media processing applications, such as three-dimensional graphics, video compression, and image processing, currently demand 10-100 billion operations per second of sustained computation. Fortunately, hundreds of arithmetic units can easily fit on a modestly sized 1cm2 chip in modern VLSI. The challenge is to provide these arithmetic units with enough data to enable them to meet the computation demands of media processing applications. Conventional storage hierarchies, which frequently include caches, are unable to bridge the data bandwidth gap between modern DRAM and tens to hundreds of arithmetic units. A data bandwidth hierarchy, however, can bridge this gap by scaling the provided bandwi...
Helmipöllö
Suomen yleisimmän pöllölajin elämää. Metsissä elävä suurisilmäinen helmipöllö oli muinoin maamme runsaslukuisin petolintu, mutta viime vuosikymmenien aikana kanta on romahtanut. Ainutlaatuisiin maastotutkimuksiin perustuva kirja tuo päivänvaloon helmipöllön elämän kiehtovimmat salat. Upeasti kuvitettu teos kertoo helmipöllön pariutumisesta, lisääntymisestä ja naaraan ja koiraan välisestä "köydenvedosta" jälkeläisten hoidossa. Helmipöllöjen ensisijaista ravintoa ovat myyrät. Myyräkantaa rajoittamalla helmipöllöt estävät myyriä tuhoamasta metsäpuiden taimia, ja samalla helmipöllöt pitävät myyrien levittämät taudit, kuten myyräkuumeen, aisoissa. Teos...
