SHORTLISTED FOR THE 2021 TWS WILDLIFE PUBLICATION AWARDS. The definitive work on Europe's largest and most spectacular owl. The Eagle Owl is one of the largest owls in the world, and is considered the most eclectic in terms of habitat, nest site and diet. An undisputed top predator, it can prey on a range of mammals up to the size of a fox, and almost every species of bird, reptile, amphibian and fish, as well as a wide spectrum of invertebrates. Surprisingly, this owl can breed almost anywhere, the female laying her eggs on a variety of natural and artificial structures over an array of altitudes. Despite being so adaptable, however, it is still a vulnerable species, and has suffered widely...
Vincenzo Penteriani and Maria del Mar Delgado are both researchers working in animal ecology and behaviour. At present, Vincenzo is a permanent researcher at the Estacion Biologica de Donana, a research centre of the Spanish Council for Scientific Research (CSIC) and Maria del Mar is a researcher in the Metapopulation Research Group at the University of Helsinki (Finland). They started their research on eagle owls in the '80s. To date, they have worked on this species in several European countries including Italy, France, Spain and Finland. Their eagle owl research projects are regularly funded by the Spanish Ministry of Economy and Competitiveness, the Excellence Projects of the Junta de Andalusia, the Finnish Academy, as well as several National and Regional Parks in Italy and France. All the photos were taken with professional and semi-professional Nikon cameras and lenses. Picture legend.

What role has natural selection played in shaping the structure and function of the vertebrate brain? This accessible book unravels the myriad adaptive explanations that have built up over decades, providing both a review and a critique of the work that has sought to explain which natural selection pressures have led to changes in brain size.
'Species' are central to understanding the origin and dynamics of biological diversity; explaining why lineages split into multiple distinct species is one of the main goals of evolutionary biology. However the existence of species is often taken for granted, and precisely what is meant by species and whether they really exist as a pattern of nature has rarely been modelled or critically tested. This novel book presents a synthetic overview of the evolutionary biology of species, describing what species are, how they form, the consequences of species boundaries and diversity for evolution, and patterns of species accumulation over time. The central thesis is that species represent more than just a unit of taxonomy; they are a model of how diversity is structured as well as how groups of related organisms evolve. The author adopts an intentionally broad approach, stepping back from the details to consider what species constitute, both theoretically and empirically, and how we detect them, drawing on a wealth of examples from microbes to multicellular organisms.
This novel text provides a concise synthesis of how the interactions between mitochondrial and nuclear genes have played a major role in shaping the ecology and evolution of eukaryotes. The foundation for this new focus on mitonuclear interactions originated from research in biochemistry and cell biology laboratories, although the broader ecological and evolutionary implications have yet to be fully explored. The imperative for mitonuclear coadaptation is proposed to be a major selective force in the evolution of sexual reproduction and two mating types in eukaryotes, in the formation of species, in the evolution of ornaments and sexual selection, in the process of adaptation, and in the evolution of senescence. The book highlights the importance of mitonuclear coadaptation to the evolution of complex life and champions mitonuclear ecology as an important subdiscipline in ecology and evolution.
This book is a concise and well-illustrated treatment of the conventional knowledge and modern utilities of earthworms. The first two chapters deal with earthworm morphology, food relationship, behavior, functional role, interaction with soil biota, and the influence of environmental factors. Earthworms found in the tropics and sub-tropics are also discussed in this section. The third chapter provides a good account of utilizing species of worms to produce high value manure through vermitechnology and its application in agriculture. The nutritional and medicinal values of earthworms are illustrated in the fourth chapter, while the fifth c provides information on how earthworms are used successfully as indicators of ecological perturbations, soil quality and for remediation of contaminated soils. The book will immensely benefit students, faculty and researchers in biological, agricultural and environmental sciences. It is also a source of information for anyone interested in knowing more about earthworms.
This novel reassessment of the field presents the central concepts in evolutionary game theory and provides an authoritative and up-to-date account. The focus is on concepts that are important for biologists in their attempts to explain observations. This strong connection between concepts and applications is a recurrent theme throughout the book.
A beautifully illustrated reference work on the biology, ecology, conservation status and management of all thirteen species of wild cattle and buffalo. This book will be a valuable resource for students, researchers, and professionals in animal behaviour, behavioural ecology, evolutionary biology and conservation biology.
This book explores the course and causes of the worldwide diffusion of democracy through an assessment of the political and economic development of individual countries from the year 1800 to 2005. Using this extended range of data and examining multiple variables, Barbara Wejnert creates a conceptual model for the diffusion of democracy and to measure national democratization. The author characterizes each nation's political system, its networking with other countries, level of development, and media advancement, in order to pinpoint what leads to national and regional progress to, or regress from, democratization. Her innovative findings challenge established thinking and reveal that the growth of literacy does not lead to democratization but is instead an outcome of democracy. She also finds that networks between non-democratic and democratic states are more important to a nation's democratization than financial aid given to non-democratic regimes or the level of national development.
