"Four productivity parameters (laying date, number of eggs, number of nestlings and number of chicks fledged) were measured over the same 10-year period for 16 territories in the Donana Park. Spearman correlation coefficient analyses ($r sb{s}$) were used to test for relationships between territory habitat characteristics, representing microhabitat, vegetative composition, degree of human influence and land use, and productivity. Egg-laying was later in territories situated closer to urban centres (n = 16 $r sb{s}$ = $-$0,529, $P

Dr Newton's book is concerned with all aspects of population regulation in diurnal birds of prey, their social behaviour, dispersion, numbers, movements, breeding and mortality. He has drawn on his own studies in Scotland and on material and investigations worldwide to produce an authoritative and stimulating synthesis of current thinking and research on the ecological problems of the Falconiformes. He also deals in detail with the effects of pesticides and other pollutants on these birds, and with their scientific management and conservation. The author's lucid style will ensure a wide readership among research workers and the more general audience with an interest in birds of prey. There is a full bibliography and an extensive appendix of tables.

« Think about how we know about past events in human history (e.g., the expansion of the Roman Empire, or the American Revolution). What types of records document those events? Now think about Earth's history, specifically the past environmental or climatic conditions at times before recorded human history. What records might there be of such conditions? Make a list of your ideas. n assemblage of five major types of natural archives of Earth's environmental and climatic history. What common feature(s) do each of these paleoclimate archives share? an assemblage of 5 major types of natural records, or archives, of Earth's environmental and climatic history. Just like a diary or other historical document, the layers in these natural archives contain indirect evidence (i.e., proxies) about past conditions and events, recorded in a sequential order. The evidence is specific to a certain time period and may be general or very detailed, depending on the rate that information was recorded. The faster the rate at which the recorder grew (trees and corals), accumulated (snow and ice), or was deposited (sedimentary sequences), the more detailed the record is, and the higher its resolution. For example, a record in which an annual signal can observed has a very high resolution. In contrast, if the finest observable details are on the order of a million years, then that record would have a low resolution. »--

Shortlisted for the 2021 TWS Wildlife Publication Awards 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 from persecution as well as other threats including electrocution on power lines, decreasing prey availability, the effects of pesticides and pollutants, and habitat alteration. Vincenzo Penteriani and María del Mar Delgado have studied this fascinating bird extensively across its vast Eurasian range. In this book, they detail its intriguing ecology, covering distribution, foraging and breeding behaviour, interspecific interactions, dispersal and conservation issues. The final two chapters provide a remarkable insight into vocal and visual communication. Scientists have long believed that owls and other crepuscular and nocturnal birds forgo the visual signals found in other avian species, but recent research on the Eagle Owl has suggested otherwise. Bringing together more than 30 years of research, The Eagle Owl tells a story rich in detail of one of the most thrilling and magnificent birds in the world.

This book provides case studies and general views of the main processes involved in the ecosystem shifts occurring in the high mountains and analyses the implications for nature conservation. Case studies from the Pyrenees are preponderant, with a comprehensive set of mountain ranges surrounded by highly populated lowland areas also being considered. The introductory and closing chapters will summarise the main challenges that nature conservation may face in mountain areas under the environmental shifting conditions. Further chapters put forward approaches from environmental geography, functional ecology, biogeography, and paleoenvironmental reconstructions. Organisms from microbes to large carnivores, and ecosystems from lakes to forest will be considered. This interdisciplinary book will appeal to researchers in mountain ecosystems, students and nature professionals. This book is open access under a CC BY license.

Current Ornithology publishes authoritative, up-to-date, scholarly reviews of topics selected from the full range of current research in avian biology. Topics cover the spectrum from the molecular level of organization to population biology and community ecology. The series seeks especially to review (1) fields in which an abundant recent literature will benefit from synthesis and organization, or (2) newly emerging fields that are gaining recognition as the result of recent discoveries or shifts in perspective, or (3) fields in which students of vertebrates may benefit from comparisons of birds with other classes. All chapters are invited, and authors are chosen for their leadership in the subjects under review.

The oak tree was a boon companion as humans expanded their presence across much of the globe. While oak woodlands (Quercus spp.) come today in stunningly diverse forms, the stately dehesas of Spain and the dramatic oak-dominated ranchlands of California are working landscapes where cultivation and manipulation for a couple of millennia have shaped Mediterranean-type ecosystems into a profoundly modified yet productive environment that is sought-after by every manner of species. The grazing of wildlife and livestock in oak woodlands yields a remarkable plant and animal biodiversity, creating a mosaic of habitats and visually pleasing savannas. Added products unique to Spain such as Iberian pigs and cork, and in California multiple landowner benefits, include valued ecosystem services that allow owners, visitors, and conservation supporters to experience the benefits of woodland life. With its 15 chapters a decade in the making, this handsomely illustrated book covers key topics in oak woodland policy, ecology, and management in Spain and California, presenting new research results and reviewing an existing expert literature.

Cork oak has historically been an important species in the western Mediterranean—ecologically as a canopy or “framework” tree in natural woodlands, and culturally as an economically valuable resource that underpins local economies. Both the natural woodlands and the derived cultural systems are experiencing rapid change, and whether or not they are resilient enough to adapt to that change is an open question. Cork Oak Woodlands on the Edge provides a synthesis of the most up-to-date, scientific, and practical information on the management of cork oak woodlands and the cultural systems that depend on cork oak. In addition, Cork Oak Woodlands on the Edge offers ten site profiles written by local experts that present an in-depth vision of cork oak woodlands across a range of biophysical, historical, and cultural contexts, with sixteen pages of full-color photos that illustrate the tree, agro-silvopastoral systems, products, resident biodiversity, and more. Cork Oak Woodlands on the Edge is an important book for anyone interested in the future of cork oak woodlands, or in the management of cultural landscapes and their associated land-use systems. In a changing world full of risks and surprises, it represents an excellent example of a multidisciplinary and holistic approach to studying, managing, and restoring an ecosystem, and will serve as a guide for other studies of this kind.
