The Great War and British identityIn the context of the centenary commemorations, the chapter discusses the influence of the First World War on the evolution of British identity. It examines how the continued reinterpretation of the First World War has reflected different, often antagonistic, yet co-existing views of Britain and what it means to identify as British.
Pain coping, pain acceptance and analgesic use as predictors of health-related quality of life among women with primary dysmenorrheaPrimary dysmenorrhea causes menstrual pain that affects women’s quality of life (QoL) and analgesics are only moderately effective. Pain coping and pain acceptance influence QoL among people affected by other chronic pain conditions, so we examined pain coping, pain acceptance and analgesic use as predictors of QoL among women with primary dysmenorrhea. 145 women with primary dysmenorrhea completed an online survey including the Menstrual Symptoms Questionnaire (MSQ), the Coping Strategies Questionnaire (CSQ), the Chronic Pain Acceptance Questionnaire (CPAQ-8), questions about analgesic use, and the Short Form-12 (SF-12), a measure of physical and mental health-related QoL. In multiple regression, pain acceptance predicted better physical and mental QoL, whereas pain coping did not predict mental or physical quality of life. Being married or cohabiting and menstrual pain that was less severe and shorter in duration predicted better physical QoL, and those effects were mediated by pain acceptance. Being older at the onset of painful periods predicted better mental QoL and that effect was also mediated by pain acceptance. More severe menstrual pain and congestive rather than spasmodic dysmenorrhea predicted worse mental QoL but those effects were not mediated by other factors. Analgesic use did not predict physical or mental QoL. The results show the impact that menstrual pain has on women’s quality of life, and suggest that initiatives to increase pain acceptance among women with menstrual pain are worthwhile. More research is needed to understand more fully the factors that influence health-related quality of life among women with menstrual pain.
Of apples and oranges? The evolution of “monogamy” in non-human primatesBehavioral ecologists, evolutionary biologists, and anthropologists have been long fascinated by the existence of “monogamy” in the animal kingdom. Multiple studies have explored the factors underlying its evolution and maintenance, sometimes with contradicting and contentious conclusions. These studies have been plagued by a persistent use of fuzzy terminology that often leads to researchers comparing “apples with oranges” (e.g., comparing a grouping pattern or social organization with a sexual or genetic mating system). In this review, we provide an overview of research on “monogamy” in mammals generally and primates in particular, and we discuss a number of problems that complicate comparative attempts to understand this issue. We first highlight why the muddled terminology has hindered our understanding of both a rare social organization and a rare mating system. Then, following a short overview of the main hypotheses explaining the evolution of pair-living and sexualmonogamy, we critically discuss various claims about the principal drivers of “monogamy” that have been made in several recent comparative studies.We stress the importance of using only high quality and comparable data. We then propose that a productive way to frame and dissect the different components of pair-living and sexual or genetic monogamy is by considering the behavioral and evolutionary implications of those components from the perspectives of all participants in a species’ social system. In particular, we highlight the importance of integrating the perspective of “floater” individuals and considering their impacts on local operational sex ratios, competition, and variance in reproductive success across a population. We stress that pair-living need not imply a reduced importance of intrasexual mate competition, a situation that may have implications for the sexual selection potential that have not yet been fully explored. Finally, we note that there is no reason to assume that different taxa and lineages, even within the same radiation, should follow the same pathway to or share a unifying evolutionary explanation for “monogamy”. The study of the evolution of pair-living, sexual monogamy, and genetic monogamy remains a challenging and exciting area of research.
Untangling the origin of ghost gear within the Maldivian archipelago and its impact on olive ridley (Lepidochelys olivacea) populationsThere is little documentation available on the impact of abandoned, lost or discarded fishing nets (‘ghost nets’) on turtle populations. Here, we utilise data collected over a 5 year period to assess (1) if a particular net type or characteristic was identifiable as entangling more turtles and (2) if particular fishing practices (i.e. types of nets) could be managed to reduce turtle entanglement in the Maldivian archipelago. A total of 131 turtles were entangled in the 752 reported ghost nets, and olive ridley turtles Lepidochelys olivacea appeared to be the most vulnerable (making up 97% of entangled turtles). However, we estimate that the 752 nets in this study, reported over a 51 month period, could have entangled between 3400 and 12200 turtles across the Indian Ocean prior to being detected in the Maldives. Mesh size, seasonality (i.e. north east monsoon), and the presence of floats were all identified as variables significantly affecting the likelihood of turtle entanglement. The probability of entanglement increased as the mesh size increased but decreased when floats were present. Additionally, turtles were more likely to be entangled during the north east monsoon when currents flow from east to west. Cluster analysis indicated that there were at least 11 broadly assigned net types found floating in the study area, and these were dominated by trawl and gill nets. Our analyses highlight the need for a detailed database of existing gear types coupled with gear marking to improve traceability of ghost nets in the Indian Ocean.
The development of an eDNA based detection method for the invasive shrimp Dikerogammarus haemobaphesDikerogammarus haemobaphes is a freshwater gammarid crustacean native to the Ponto-Caspian region. However, the species is rapidly spreading throughout Western Europe and is classed as a highly invasive species. Here we present a novel eDNA assay aimed at detecting D. haemobaphes and demonstrate its suitability with validation steps conducted in-silico (computer simulations), ex-situ (test of specificity using closely related species) and in-situ (within the field). A survey of freshwater systems in the West-Midlands, United Kingdom, highlighted that D. haemobaphes was present in 26 out of the 39 sites assessed. We conclude that eDNA detection for D. haemobaphes is a promising tool for assessing and mapping the presence/distribution of this invasive amphipod.
