Migration is a widespread, critical, and increasingly-threatened behavior expressed by diverse animal taxa. Beyond being one of the most awe-inspiring biological phenomena on Earth, migration also plays a key role in ecosystem functioning worldwide. Despite the prevalence of this behavior and its ecological and evolutionary significance, migration is a complex behavior, leaving significant knowledge gaps in understanding how animals navigate environmental variability and human-induced rapid environmental change in deciding when and where to migrate. This gap stems in part from the difficulty of observing and integrating individual-level and population-level behavior of migratory species in the wild, especially in oceanic ecosystems. The complexity and scale of animal migration also challenges applied ecologists and natural resource managers to develop more dynamic management strategies for the protection of migratory species alongside human resource use. In this dissertation, I aim to advance both theoretical and applied ecological understanding of animal migration by exploring the role of social cues and environmental variability in migration, linking individual and population-level behavior for observation of migration in remote ecosystems (specifically in the migratory Eastern North Pacific blue whale population), and considering the tools and strategies required for dynamic and equitable management of migratory populations and the ecosystems they inhabit.

Despite the wealth of natural historical research conducted on migration over decades, there is still a dearth of hypothesis-driven studies that fully integrate theory and empirical analyses to understand the causes and consequences of migration, and a taxonomic bias towards birds in much migration research. This book takes a comparative, integrated view of animal migration, linking evolution with ecology and management, theory with empirical research, and embracing all the major migratory taxa (including human pastoralists). The scope extends beyond the target organism to consider the ecosystem-level dynamics of migration. The emphasis is on exciting new research avenues that are now opening up, whether due to advances in our understanding of migration as a biological phenomenon or through the availability of a range of new technologies. Broad themes that emerge include integrating migration into the broad spectrum of movement behaviour, the need for a comparative and cross-taxonomic approach that considers migration at a range of temporal and spatial scales, and examination of the key roles of resource uncertainty and spatial heterogeneity in driving migratory behaviour. The book identifies the potential for new tools to revolutionise the study of migration, including satellite-tracking technology, genomics, and modelling - all of which are linked to increasing computing power. We are now on the verge of a breakthrough in migration research, which is crucial given the multiple threats that face the conservation of migration as a phenomenon, including climate change.

The pervasive perturbation of natural systems by human activities has rapidly changed the social context of many free-ranging animals, potentially reducing the efficiency of reproductive strategies, as well as the effective population size (Ne). Behavioral flexibility can be beneficial to species confronted with rapid contextual change, and the range of flexibility may ultimately influence whether a species can buy the time needed to respond adaptively to change. From the perspective of conservation management, an understanding of species' behavioral flexibility may improve predictions regarding the effects of rapid environmental change on populations, and facilitate the application of behavioral knowledge to conservation management. Fundamentally, an animal's decision-making processes are responsible for generating flexible behavioral responses, thus the lability of mechanisms underpinning decision-making influences the flexibility of behavioral responses. Here I evaluate the study of animal decision-making across scientific disciplines. I critically assess the use of animal decision-making in conservation and suggest ways in which decision theory could enhance conservation strategies. My empirical research is focused on the influence of social context on behavioral flexibility in the endangered giant panda (Ailuropoda melanoleuca). The panda is a compelling species in which to study behavioral flexibility in the conservation context, because they are solitary, and females are seasonally-monoestrus and ovulate spontaneously. While energetic constraints play a prominent role in reproductive strategies, little is known regarding their mating system or the plasticity of reproductive behavior. Pandas are behaviorally expressive, using multiple modes of signaling during courtship, however, a holistic understanding of multimodal signaling in the species is lacking. Further, although populations are depleted throughout most of their range, the influence of social context on behavior and communication has not been described. Here we show that female signaling effort is generally lower in the exclusive presence of other females, suggesting that females can modify their behavioural efforts during the pre-ovulatory period according to the prevailing social context. We also found that multimodal signaling during social interactions did not consistently evoke an immediate, discrete response from receivers. Together these findings suggest that giant pandas demonstrate a limited degree of flexible behavioral responses dependent upon the prevailing social context.

P. Berthold and E. Gwinnd Bird migration is an intriguing aspect of the living world - so much so that it has been investigated for as long, and as thoroughly, as almost any other natural phenomenon. Aristotle, who can count as the founder of scientific ornithology, paid very close attention to the migrations of the birds he ob served, but it was not until the reign of Friedrich II, in the first half of the 13th century, that reliable data began to be obtained. From then on, the data base grew rapidly. Systematic studies of bird migration were introduced when the Vogelwarte Rossitten was founded, as the first ornithological biological observation station in the world (see first chapter "In Memory of Vogelwarte Rossitten"). This area later received enormous impetus when ex perimental research on the subject was begun: the large-scale bird-ringing experiment initiated in Rossitten in 1903 by Johannes Thienemann (who was inspired by the pioneering studies of C. C. M. Mortensen), the experiments on photoperiodicity carried out by William Rowan in the 1920s in Canada and retention and release experiments performed by Thienemann in the 1930s in Rossitten, the first experimental study on the orientation of migratory birds. After the Second World War, migration research, while continuing in the previous areas, also expanded into new directions such as radar ornithology, ecophysiology and hormonal control mechanisms, studies of evolution, ge netics, telemetry and others.

Changes in seasonal movements and population dynamics of migratory birds in response to ongoing changes resulting from global climate changes are a topic of great interest to conservation scientists and birdwatchers around the world. Because of their dependence on specific habitats and resources in different geographic regions at different phases of their annual cycle, migratory species are especially vulnerable to the impacts of climate change. In Bird Migration and Global Change, eminent ecologist George W. Cox brings his extensive experience as a scientist and bird enthusiast to bear in evaluating the capacity of migratory birds to adapt to the challenges of a changing climate. Cox reviews, synthesizes, and interprets recent and emerging science on the subject, beginning with a discussion of climate change and its effect on habitat, and followed by eleven chapters that examine responses of bird types across all regions of the globe. The final four chapters address the evolutionary capacity of birds, and consider how best to shape conservation strategies to protect migratory species in coming decades. The rate of climate change is faster now than at any other moment in recent geological history. How best to manage migratory birds to deal with this challenge is a major conservation issue, and Bird Migration and Global Change is a unique and timely contribution to the literature.

Human-induced environmental change currently represents the single greatest threat to global biodiversity. Species are typically adapted to the local environmental conditions in which they have evolved. Changes in environmental conditions initially influence behaviour, which in turn affects species interactions, population dynamics, evolutionary processes and, ultimately, biodiversity. How animals respond to changed conditions, and how this influences population viability, is an area of growing research interest. Yet, despite the vital links between environmental change, behaviour, and population dynamics, surprisingly little has been done to bridge these areas of research. Behavioural Responses to a Changing World is the first book of its kind devoted to understanding behavioural responses to environmental change. The volume is comprehensive in scope, discussing impacts on both the mechanisms underlying behavioural processes, as well as the longer-term ecological and evolutionary consequences. Drawing on international experts from across the globe, the book covers topics as diverse as endocrine disruption, learning, reproduction, migration, species interactions, and evolutionary rescue.
