Leaving Spain

Since the beginning of the economic crisis of 2008, Spain, like other Southern European countries, has witnessed a mass departure of mostly young people looking for opportunities abroad. Leaving Spain is based on 58 autobiographical narrative interviews with recent Spanish migrants who went to the UK and Germany, and sometimes returned. By presenting a combination of in-depth case studies and comparative analyses, the author demonstrates the potential of biographical research and narrative analysis in studying contemporary Europe, including its overlapping crises. The scope of the sociological study is not limited to examining how those who left Spain experienced single phases of their migration. Instead, it focuses on the significance of migration projects in the context of their life histories and how they make sense of these experiences in retrospect. This book will not only be of great interest to social scientists and students in different disciplines and interdisciplinary studies such as sociology, anthropology, human geography, European studies, education, and social work, but also to professionals, European and national policy makers, and those interested in learning more about migrants’ experiences, perspectives, and (often invisible) contributions.

Brown Seaweeds (Phaeophyceae) of Britain and Ireland

Brown Seaweeds (Phaeophyceae) of Britain and Ireland provides the first complete, up-to-date, detailed illustrated guide and keys to the nearly 200 species of brown algae present around the coasts of Britain and Ireland. It is the culmination of over 30 years of field and laboratory studies by the author. Following an exhaustive introduction that covers the biology and ecology of brown seaweeds, a checklist of species is set out, followed by clear and user-friendly keys to the genera. Particular attention is then paid to providing detailed illustrations, and the volume holds more than 300 compound plates of line drawings and photographs in its extensive taxonomic treatment. Comprehensive information is given on the geographical and seasonal distributions, synonymy, morphology, anatomy, cytology, reproduction, life histories, taxonomy, systematics and bibliographic material pertaining to each species. Notably, this flora offers a much fuller consideration of many of the lesser known, more cryptic microscopic brown algae than previously available. Further, the book also contains the results of much original research undertaken by the author. This will surely remain a standard reference work on brown seaweeds for many years to come – an indispensable research tool and field guide for phycologists and students throughout the North Atlantic region and beyond.

The Traumatic Life Experiences and Ontological Well-Being: Insights from Narrative Psychology and Self-Memory Theory

Ontological well-being adopts a holistic perspective on well-being similar to the narrative psychology when analyzing life histories by referring to past, present, and future aspects of one's life. Relatedly, the self-memory view proposes that life events are self-evaluated. Based on the narrative psychology and self-memory approach, affective life events and emotions are processed in the memory and play a role in structuring self-perceptions and psychological well-being. Therefore, turbulent external conditions such as the pandemic, uncertain environments and socio-economic challenges may lead to traumatic experiences for individuals. Being exposed to traumatic events and experiencing post-traumatic stress harms mental health, well-being, and work performance. This study aims to examine the relationship between traumatic life experiences and ontological well-being within the period of COVID 19 pandemic. It is intended to reveal the impact of traumatic experiences on ontological well-being of individuals in work life. A cross-sectional study was utilized throughout an online survey with the participation of 270 employees working in various private organizations. Following the statistical analyses, the findings were evaluated and both conceptual and practical discussions were provided.

Latitudinal but not elevational variation in blood glucose level is linked to life history across passerine birds

Macrophysiological research is vital to our understanding of mechanisms underpinning global life history variation and adaptation under diverse environments. Birds represent an important model taxon in this regard, yet our knowledge is limited to only a few physiological traits, mostly studied in temperate and Neotropical species. Here, we examined latitudinal and elevational variation in an emerging biomarker of physiological pace of life, blood glucose concentration, collected from 61 European temperate and 99 Afrotropical passerine species. Our data suggest that the slow physiological pace-of-life syndrome, indicated by lower baseline glucose level and stronger stress response, evolves convergently in lowland tropical birds across continents and is shaped by their low fecundity. In contrast, elevational variation in blood glucose levels implied a unique montane pace-of-life syndrome combining slow-paced life histories with fast-paced physiology. The observed patterns suggest an unequal importance of life history in shaping physiological adaptations associated with latitude and elevation.

Short-lived species move uphill faster under climate change

Climate change is pushing species ranges and abundances towards the poles and mountain tops. Although many studies have documented local altitudinal shifts, knowledge of general patterns at a large spatial scale, such as a whole mountain range, is scarce. From a conservation perspective, studying altitudinal shifts in wildlife is relevant because mountain regions often represent biodiversity hotspots and are among the most vulnerable ecosystems. Here, we examine whether altitudinal shifts in birds’ abundances have occurred in the Scandinavian mountains over 13 years, and assess whether such shifts are related to species’ traits. Using abundance data, we show a clear pattern of uphill shift in the mean altitude of bird abundance across the Scandinavian mountains, with an average speed of 0.9 m per year. Out of 76 species, 7 shifted significantly their abundance uphill. Altitudinal shift was strongly related to species’ longevity: short-lived species showed more pronounced uphill shifts in abundance than long-lived species. The observed abundance shifts suggest that uphill shifts are not only driven by a small number of individuals at the range boundaries, but the overall bird abundances are on the move. Overall, the results underscore the wide-ranging impact of climate change and the potential vulnerability of species with slow life histories, as they appear less able to timely respond to rapidly changing climatic conditions.

Echoes of the hunt? An inter-continental comparison of patterns of growth and determinants of size of brown bears in Canada and Sweden.

Comparing life history traits among populations that have been separated genetically for several hundred thousand years, but live in similar habitats on different continents, may help us understand how ecological and anthropomorphic factors shape life histories. We compared patterns of growth in body length and mass, and the influence of population density, habitat quality (NDVI), and reproduction on age-specific length and mass of male and female brown bears between Alberta, Canada, and Sweden. We found that Swedish females were significantly smaller in both length and mass than Alberta females. Swedish females also reached primiparity earlier and at a smaller mass and length. However, there were no continental differences in the patterns of growth in males. We found strong positive effects of NDVI, but only weak negative effects of population density on female mass and length in both areas. Generally, especially mass of Alberta females was more strongly affected by NDVI and density than for Swedish females. Reproduction had stronger negative effects on female mass in Alberta than in Sweden. We found no effects of NDVI and population density on male mass and body length in both areas. The larger variation in female growth and size between the areas, in contrast to males, may be related to differences in female reproductive investment due to differences in population trends, i.e., earlier reproduction in increasing populations or populations below carrying capacity, or to different selection pressures in the past, potentially due to human persecution. Swedish females exhibited characteristics typical of increasing populations, whereas Alberta females exhibited characteristics typical of stable or decreasing populations. The difference in reproduction investment means that Swedish bears can be harvested at higher rates, whereas Alberta bears must be managed more conservatively.

Processional Culture and Black Mobility in Maggie Washington's Wilmington

This article addresses changes in the built environment of the postbellum American South through an examination of the life histories, parade routes, and costuming practices of the Afro-Caribbean Jonkonnu masking tradition. I juxtapose the stories of two practitioners of the tradition across the color line in turn-of-the-twentieth-century Wilmington, North Carolina. Using a material culturally inflected approach to the study of landscapes, I use these two narratives to deepen the histories of African American processional cultures toward a longer time span and a more immersive, performer-oriented approach. Though few conventional objects of ornamentation and display from these practices survive, this article posits that an approach rooted in the materiality of landscape can help uncover festive cultures that have been understudied or undertheorized in more conventional historical approaches. Further, the ubiquitous presence of Jonkonnu and other Black processional traditions in the post-emancipation city suggests the importance of these and other objects, practices, and larger cultures of celebration in combating white supremacist culture.

A modern baseline for the paired isotopic analysis of skin and bone in terrestrial mammals

We present the isotopic discrimination between paired skin and bone collagen from animals of known life history, providing a modern baseline for the interpretation of archaeological isotopic data. At present, the interpretation of inter-tissue variation (Δ (skin–bone) ) in mummified remains is based on comparisons with other archaeological material, which have attributed divergence to their contrasting turnover rates, with rapidly remodelling skin collagen incorporating alterations in environmental, cultural and physiological conditions in the months prior to death. While plausible, the lack of baseline data from individuals with known life histories has hindered evaluation of the explanations presented. Our analysis of a range of animals raised under a variety of management practices showed a population-wide trend for skin collagen to be depleted in 13 C by –0.7‰ and enriched in 15 N by +1.0‰ relative to bone collagen, even in stillborn animals. These results are intriguing and difficult to explain using current knowledge; however, on the basis of the findings reported here, we caution any results which interpret simply on differing turnover rates. We hypothesize that there may be a consistent difference in the routing of dietary protein and lipids between skin and bone, with potentially on-site synthesis of non-essential amino acids using carbon and nitrogen that have been sourced via different biochemical pathways.

Long distance homing in the cane toad (Rhinella marina) in its native range

Many animals exhibit complex navigation over different scales and environments. Navigation studies in amphibians have largely focused on species with life histories that require accurate spatial movements, such as territorial poison frogs and migratory pond-breeding amphibians that show fidelity to mating sites. However, other amphibian species have remained relatively understudied, leaving open the possibility that well-developed navigational abilities are widespread. Here, we measured short-term space use in non-territorial, non-migratory cane toads (Rhinella marina) in their native range in French Guiana. After establishing site fidelity, we tested their ability to return home following translocations of 500 and 1000 meters. Toads were able to travel in straight trajectories back to home areas, suggesting navigational abilities similar to those observed in amphibians with more complex spatial behavior. These observations break with the current paradigm of amphibian navigation and suggest that navigational abilities may be widely shared among amphibians.
