Phylogeny and biogeography of the wingless orthopteran family Rhaphidophoridae.

Cave crickets (Rhaphidophoridae) are insects of an ancient and wingless lineage within Orthoptera that are distributed worldwide except in Antarctica, and each subfamily has a high level of endemicity. Here, we show the comprehensive phylogeny of cave crickets using multi-gene datasets from mitochondrial and nuclear loci, including all extant subfamilies for the first time. We reveal phylogenetic relationships between subfamilies, including the sister relationship between Anoplophilinae and Gammarotettiginae, based on which we suggest new synapomorphies. Through biogeographic analyses based on divergence time estimations and ancestral range reconstruction, we propose novel hypotheses regarding the biogeographic history of cave crickets. We suggest that Gammarotettiginae in California originated from the Asian lineage when Asia and the Americas were connected by the Bering land bridge, and the opening of the western interior seaway affected the division of Ceuthophilinae from Tropidischiinae in North America. We estimate that Rhaphidophoridae originated at 138 Mya throughout Pangea. We further hypothesize that the loss of wings in Rhaphidophoridae could be the result of their adaptation to low temperatures in the Mesozoic era.

Range and climate niche shifts in European and North American breeding birds.

Species respond dynamically to climate change and exhibit time lags. Consequently, species may not occupy their full climatic niche during range shifting. Here, we assessed climate niche tracking during recent range shifts of European and United States (US) birds. Using data from two European bird atlases and from the North American Breeding Bird Survey between the 1980s and 2010s, we analysed range overlap and climate niche overlap based on kernel density estimation. Phylogenetic multiple regression was used to assess the effect of species morphological, ecological and biogeographic traits on range and niche metrics. European birds shifted their ranges north and north-eastwards, US birds westwards. Range unfilling was lower than expected by null models, and niche expansion was more common than niche unfilling. Also, climate niche tracking was generally lower in US birds and poorly explained by species traits. Overall, our results suggest that dispersal limitations were minor in range shifting birds in Europe and the USA while delayed extinctions from unfavourable areas seem more important. Regional differences could be related to differences in land use history and monitoring schemes. Comparative analyses of range and niche shifts provide a useful screening approach for identifying the importance of transient dynamics and time-lagged responses to climate change.

Legacies of millennial-scale climate oscillations in contemporary biodiversity in eastern North America.

The Atlantic meridional overturning circulation (AMOC) has caused significant climate changes over the past 90 000 years. Prior work has hypothesized that these millennial-scale climate variations effected past and contemporary biodiversity, but the effects are understudied. Moreover, few biogeographic models have accounted for uncertainties in palaeoclimatic simulations of millennial-scale variability. We examine whether refuges from millennial-scale climate oscillations have left detectable legacies in the patterns of contemporary species richness in eastern North America. We analyse 13 palaeoclimate estimates from climate simulations and proxy-based reconstructions as predictors for the contemporary richness of amphibians, passerine birds, mammals, reptiles and trees. Results suggest that past climate changes owing to AMOC variations have left weak but detectable imprints on the contemporary richness of mammals and trees. High temperature stability, precipitation increase, and an apparent climate fulcrum in the southeastern United States across millennial-scale climate oscillations aligns with high biodiversity in the region. These findings support the hypothesis that the southeastern United States may have acted as a biodiversity refuge. However, for some taxa, the strength and direction of palaeoclimate-richness relationships varies among different palaeoclimate estimates, pointing to the importance of palaeoclimatic ensembles and the need for caution when basing biogeographic interpretations on individual palaeoclimate simulations. This article is part of the theme issue 'Ecological novelty and planetary stewardship: biodiversity dynamics in a transforming biosphere'.

The ratting of North America: A 350-year retrospective on Rattus species compositions and competition.

While the impacts of black (Rattus rattus) and brown (Rattus norvegicus) rats on human society are well documented-including the spread of disease, broad-scale environmental destruction, and billions spent annually on animal control-little is known about their ecology and behavior in urban areas due to the challenges of studying animals in city environments. We use isotopic and ZooMS analysis of archaeological (1550s-1900 CE) rat remains from eastern North America to provide a large-scale framework for species arrival, interspecific competition, and dietary ecology. Brown rats arrived earlier than expected and rapidly outcompeted black rats in coastal urban areas. This replacement happened despite evidence that the two species occupy different trophic positions. Findings include the earliest molecularly confirmed brown rat in the Americas and show a deep ecological structure to how rats exploit human-structured areas, with implications for understanding urban zoonosis, rat management, and ecosystem planning as well as broader themes of rat dispersal, phylogeny, evolutionary ecology, and climate impacts.

Psychosocial factors associated with overdose subsequent to Illicit Drug use: a systematic review and narrative synthesis.

BACKGROUND AND AIMS: Psychological and social status, and environmental context, may mediate the likelihood of experiencing overdose subsequent to illicit drug use. The aim of this systematic review was to identify and synthesise psychosocial factors associated with overdose among people who use drugs. METHODS: This review was registered on Prospero (CRD42021242495). Systematic record searches were undertaken in databases of peer-reviewed literature (Medline, Embase, PsycINFO, and Cinahl) and grey literature sources (Google Scholar) for work published up to and including 14 February 2023. Reference lists of selected full-text papers were searched for additional records. Studies were eligible if they included people who use drugs with a focus on relationships between psychosocial factors and overdose subsequent to illicit drug use. Results were tabulated and narratively synthesised. RESULTS: Twenty-six studies were included in the review, with 150,625 participants: of those 3,383-4072 (3%) experienced overdose. Twenty-one (81%) studies were conducted in North America and 23 (89%) reported polydrug use. Psychosocial factors associated with risk of overdose (n = 103) were identified and thematically organised into ten groups. These were: income; housing instability; incarceration; traumatic experiences; overdose risk perception and past experience; healthcare experiences; perception of own drug use and injecting skills; injecting setting; conditions with physical environment; and social network traits. CONCLUSIONS: Global rates of overdose continue to increase, and many guidelines recommend psychosocial interventions for dependent drug use. The factors identified here provide useful targets for practitioners to focus on at the individual level, but many identified will require wider policy changes to affect positive change. Future research should seek to develop and trial interventions targeting factors identified, whilst advocacy for key policy reforms to reduce harm must continue.

Invasibility of a North American soil ecosystem to amphibian-killing fungal pathogens.

North American salamanders are threatened by intercontinental spread of chytridiomycosis, a deadly disease caused by the fungal pathogen Batrachochytrium salamandrivorans (Bsal). To predict potential dispersal of Bsal spores to salamander habitats, we evaluated the capacity of soil microbial communities to resist invasion. We determined the degree of habitat invasibility using soils from five locations throughout the Great Smoky Mountains National Park, a region with a high abundance of susceptible hosts. Our experimental design consisted of replicate soil microcosms exposed to different propagule pressures of the non-native pathogen, Bsal, and an introduced but endemic pathogen, B. dendrobatidis (Bd). To compare growth and competitive interactions, we used quantitative PCR, live/dead cell viability assays, and full-length 16S rRNA sequencing. We found that soil microcosms with intact bacterial communities inhibited both Bsal and Bd growth, but inhibitory capacity diminished with increased propagule pressure. Bsal showed greater persistence than Bd. Linear discriminant analysis (LDA) identified the family Burkolderiaceae as increasing in relative abundance with the decline of both pathogens. Although our findings provide evidence of environmental filtering in soils, such barriers weakened in response to pathogen type and propagule pressure, showing that habitats vary their invasibility based on properties of their local microbial communities.

Significant shifts in latitudinal optima of North American birds.

Changes in climate can alter environmental conditions faster than most species can adapt. A prediction under a warming climate is that species will shift their distributions poleward through time. While many studies focus on range shifts, latitudinal shifts in species' optima can occur without detectable changes in their range. We quantified shifts in latitudinal optima for 209 North American bird species over the last 55 y. The latitudinal optimum (m) for each species in each year was estimated using a bespoke flexible non-linear zero-inflated model of abundance vs. latitude, and the annual shift in m through time was quantified. One-third (70) of the bird species showed a significant shift in their optimum. Overall, mean peak abundances of North American birds have shifted northward, on average, at a rate of 1.5 km per year (±0.58 SE), corresponding to a total distance moved of 82.5 km (±31.9 SE) over the last 55 y. Stronger poleward shifts at the continental scale were linked to key species' traits, including thermal optimum, habitat specialization, and territoriality. Shifts in the western region were larger and less variable than in the eastern region, and they were linked to species' thermal optimum, habitat density preference, and habitat specialization. Individual species' latitudinal shifts were most strongly linked to their estimated thermal optimum, clearly indicating a climate-driven response. Displacement of species from their historically optimal realized niches can have dramatic ecological consequences. Effective conservation must consider within-range abundance shifts. Areas currently deemed "optimal" are unlikely to remain so.

Influence of temporary emigration on wood turtle (Glyptemys insculpta) detectability, with implications for abundance estimation.

Reliable population estimates are important for making informed management decisions about wildlife species. Standardized survey protocols have been developed for monitoring population trends of the wood turtle (Glyptemys insculpta), a semi-aquatic freshwater turtle species of conservation concern throughout its distribution in east-central North America. The protocols use repeated active search surveys of defined areas, allowing for estimation of survey-specific detection probability (p) and site-specific abundance. These protocols assume population closure within the survey area during the survey period, which is unlikely to be met as wood turtles are a highly mobile species. Additionally, current protocols use a single-pass design that does not allow for separation of availability (pa) and detectability (pd). If there are systematic influences on pa or pd that are not accounted for in the survey design or data analysis, then resulting abundance estimates could be biased. The objectives of this study were to determine if pa is a random process and if pa and pd are influenced by demographic characteristics. We modified the wood turtle survey protocol used in the upper Midwest to include a double-pass design, allowing us to estimate pa and pd using a robust design capture-recapture model. The modified protocol was implemented at 14 wood turtle monitoring sites in Minnesota and Wisconsin between 2017 and 2022. Our results indicated that pa was non-random and that pd increased with turtle carapace length. Our study suggests that model assumptions for current wood turtle population models may be violated, likely resulting in an overestimation of abundance. We discuss possible protocol and modeling modifications that could result in more accurate wood turtle abundance estimates.

Identifying research gaps in climate-related mental health outcomes in North America and Europe: a qualitative framework analysis.

BACKGROUND: Climate change and mental health outcomes are two of the most pressing global crises. Despite the increasing global mental health burden, climate-related mental health outcomes research is nascent and isolated, with substantial gaps across regions and disciplines. Connecting Climate Minds is a global initiative connecting researchers, experts, and people with lived experience of adverse mental health outcomes to identify regional research needs and create a community to support improved climate-related mental health outcomes. METHODS: We focused on North America and Europe as part of the global Connecting Climate Minds effort, using semi-structured interviews, focus groups, regional dialogues (ie, discussions between experts in climate health, planetary health, human health, and mental health and with lived experience to discuss the climate threats most affecting their communities, their effects on mental health, and opportunities for action), and a literature review to identify crucial research gaps in climate change and mental health. We collected insights into priorities when addressing mental health outcomes related to climate change in Europe and North America; requirements for effective research, policy, and practice; and encouraging collaboration from a diverse community that included experts, researchers, practitioners from multiple disciplines, indigenous groups, and youth representatives. We used a qualitative framework analysis to identify consensus priorities. FINDINGS: Several themes emerged regarding research gaps. First, research into the effects of climate change on mental health is needed (eg, how pre-existing mental health outcomes are affected by climate disaster events, risk factors and protective factors, the effects of climate action or inaction on mental health, and economic costs). Second, investigating connections between climate-related mental health outcomes and Indigenous and other cultural practices (eg, the effects of climate change on Indigenous peoples and practices, cultural variations in mental health responses, and the effectiveness of integrating Indigenous and cultural knowledge into mental health interventions). Third, mixed-methods research is needed to explore the relationships between climate change, global and national economies, and governance and their associations with mental health outcomes. Fourth, evaluating social and cultural connectedness in mental health outcomes and climate change, community-level interventions, and the effectiveness of climate-education programmes that incorporate mental health considerations are research priorities. Finally, understanding how emerging technology can be used to understand climate-related mental health outcomes and use of technology to collect, analyse, and respond to population health data (with ethical considerations). INTERPRETATION: Connecting Climate Minds aims to psychologically equip people in Europe and North America to navigate the challenges of a changing climate. Climate-related mental health experts in should collaborate and encourage research and action that are proactive, community-led, and accessible. FUNDING: Imperial College London, the Wellcome Trust, and the Planetary Health Alliance via Harvard University.

Whale evolution: Ancient toothed relative of baleen whales breaches northward.

The mysticetes - baleen whales and their toothed ancestors - have a long evolutionary history that, despite many recent paleontological discoveries, remains highly debated. The description of a new mysticete from the latest Eocene of North America opens promising new research directions.

Landscape of Métis health and wellness: protocol for a scoping review.

INTRODUCTION: In Canada, Métis people are one of three distinct Indigenous peoples whose rights are recognised and affirmed in Section 35 of the federal Constitution Act, 1982. In line with Métis people having a unique culture, history, language and way of life, a distinctions-based approach is critical to understand the current landscape of Métis-specific health. In this paper, we present a scoping review protocol to describe this research landscape in Canada led by the Métis Nation of Ontario (MNO). METHODS AND ANALYSIS: This scoping review protocol is reported in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews reporting guidelines and follows Arksey and O'Malley's scoping review methodology. We will search electronic databases (Scopus, MEDLINE, Embase, Web of Science, CINAHL, APA PsycINFO, Anthropology Plus, Bibliography of Indigenous Peoples of North America, Canadian Business and Current Affairs, Indigenous Studies Portal, Informit Indigenous Collection, Collaborative Indigenous Garden, PubMed, ProQuest), grey literature sources and reference lists from selected papers. Two reviewers (HMB and SK) will double-blind screen all titles/abstracts and full-text studies for inclusion. Any health-related study or health report that includes a Métis-specific health, well-being or Métis social determinant of health outcome will be included. Relevant variables will be extracted following an iterative process whereby the data charting will be reviewed and updated. ETHICS AND DISSEMINATION: Findings from this scoping review will be shared back through the MNO's existing community-based communication channels. Traditional academic dissemination will also be pursued. Research ethics board approval is not required, since data are from peer-reviewed publications or publicly shared health reports and knowledge translation products.

Gray whale (Eschrichtius robustus) post-mortem findings from December 2018 through 2021 during the Unusual Mortality Event in the Eastern North Pacific.

Beginning in December 2018, increased numbers of gray whale (Eschrichtius robustus) strandings were reported along the west coast of Mexico, the United States, and Canada, prompting declaration of a gray whale Unusual Mortality Event (UME) by the United States National Marine Fisheries Service. Although strandings declined in 2020 and 2021 from a peak in 2019, the UME is still ongoing as of fall 2023. Between 17 December 2018 and 31 December 2021, 503 animals stranded along the west coast of North America, with 226 strandings in Mexico, 71 in California, 12 in Oregon, 56 in Washington, 21 in British Columbia, and 117 in Alaska. These included 187 males, 167 females, and 149 whales of undetermined sex; and 193 adults, 194 subadults, 40 calves, 1 fetus, and 75 whales of undetermined age class. We report on 61 of the 503 carcasses (12%) that had external and internal gross necropsy and/or histopathology data: of these 61 whales, findings that contributed to death were identified in 33 (54%) whales. Sixteen of the 61 (26%) were severely emaciated. Gross lesions of blunt force trauma consistent with vessel strike were identified in 11 of the 61 animals (18%), only two of which were emaciated. Two whales (3%) were entangled at time of death, and one died from entrapment. Signs of killer whale (Orcinus orca) interaction were documented in 19 of the 61 animals; five were deemed from recent interactions and three (5%) likely contributed to mortality. A specific cause of death could not be identified in 28 of 61 whales (46%). Additionally, logistical challenges and the advanced state of decomposition of most examined carcasses precluded detection of potential infectious or toxic causes of morbidity or mortality. Up to 2016, the eastern North Pacific population of gray whale population had generally been increasing since the cessation of historic whaling and a prior UME in 1999-2000. However, recent abundance and calf production estimates have declined, a trend that overlaps the current UME. The relative contributions of carrying capacity, environmental change, prey shifts, and infectious, toxic, and other processes to the increased gray whale mortalities have not yet been resolved. Nevertheless, the marked temporal increase in strandings, including findings of malnutrition in some of the whales, along with low calf production, likely represent consequences of complex and dynamic ecological interactions in the ocean impacting the population.

Drought triggers and sustains overnight fires in North America.

Overnight fires are emerging in North America with previously unknown drivers and implications. This notable phenomenon challenges the traditional understanding of the 'active day, quiet night' model of the diurnal fire cycle1-3 and current fire management practices4,5. Here we demonstrate that drought conditions promote overnight burning, which is a key mechanism fostering large active fires. We examined the hourly diurnal cycle of 23,557 fires and identified 1,095 overnight burning events (OBEs, each defined as a night when a fire burned through the night) in North America during 2017-2020 using geostationary satellite data and terrestrial fire records. A total of 99% of OBEs were associated with large fires (>1,000 ha) and at least one OBE was identified in 20% of these large fires. OBEs were early onset after ignition and OBE frequency was positively correlated with fire size. Although warming is weakening the climatological barrier to night-time fires6, we found that the main driver of recent OBEs in large fires was the accumulated fuel dryness and availability (that is, drought conditions), which tended to lead to consecutive OBEs in a single wildfire for several days and even weeks. Critically, we show that daytime drought indicators can predict whether an OBE will occur the following night, which could facilitate early detection and management of night-time fires. We also observed increases in fire weather conditions conducive to OBEs over recent decades, suggesting an accelerated disruption of the diurnal fire cycle.

Phylogenomics of Tetraopes longhorn beetles unravels their evolutionary history and biogeographic origins.

Tetraopes longhorn beetles are known for their resistance to milkweed plant toxins and their coevolutionary dynamics with milkweed plants (Asclepias). This association is considered a textbook example of coevolution, in which each species of Tetraopes is specialized to feed on one or a few species of Asclepias. A major challenge to investigating coevolutionary hypotheses and conducting molecular ecology studies lies in the limited understanding of the evolutionary history and biogeographical patterns of Tetraopes. By integrating genomic, morphological, paleontological, and geographical data, we present a robust phylogeny of Tetraopes and their relatives, using three inference methods with varying subsets of data, encompassing 2-12 thousand UCE loci. We elucidate the diversification patterns of Tetraopes species across major biogeographical regions and their colonization of the American continent. Our findings suggest that the genus originated in Central America approximately 21 million years ago during the Miocene and diversified from the Mid-Miocene to the Pleistocene. These events coincided with intense geological activity in Central America. Additionally, independent colonization events in North America occurred from the Late Miocene to the early Pleistocene, potentially contributing to the early diversification of the group. Our data suggest that a common ancestor of Tetraopini migrated into North America, likely facilitated by North Atlantic land bridges, while closely related tribes diverged in Asia and Europe during the Paleocene. Establishing a robust and densely sampled phylogeny of Tetraopes beetles provides a foundation for investigating micro- and macroevolutionary phenomena, including clinal variation, coevolution, and detoxification mechanisms in this ecologically important group.

A Systematic Scoping Review of Indigenous People's Experience of Healing and Recovery from Child Sexual Abuse.

Child sexual abuse is a form of violence that occurs across nations and cultures. Collective efforts are being made to address this issue within many Indigenous communities. In Australia, Aboriginal and Torres Strait Islander communities have expressed the need for cultural models of healing child sexual abuse. A preliminary exploration of the relevant literature shows a lack of synthesis with regard to the current evidence base. This protocol outlines the methods and background for a scoping review that aims to explore and collate the broad scope of literature related to healing from child sexual abuse within an Indigenous context. The proposed review utilises a 'population, concept, and context structure' from the Joanna Briggs Institute to explore the broad scope of the literature within a scoping review framework. The target population is Indigenous survivors of child sexual abuse, including Indigenous populations from six distinct regions: Aboriginal and Torres Strait Islander peoples from Australia; Maori peoples from Aotearoa (New Zealand); First Nations, Inuit and Métis peoples from Canada; Native American peoples from North America; Native peoples from Alaska; and the Sámi peoples of the Sápmi region in Northern Europe. The concept within the review is healing from an Indigenous perspective, which includes a broad range of processes related to both recovery and personal growth. The contexts explored within this review are any context in which healing from child sexual abuse can occur. This may include processes related to disclosure and accessing services, specific interventions or programs for survivors of child sexual abuse, as well as broader non-specific healing programs and personal experiences of healing without intervention. The scoping review will use search strings with broad inclusion and exclusion criteria to capture the potential breadth of perspectives. The search will be conducted across several academic databases and will also include an extensive search for grey literature. This protocol establishes the proposed benefits of this scoping review.

A trend, analysis, and solution on women's representation in diagnostic radiology in North America: a narrative review.

Despite the demonstrated benefits of gender diversity in medicine, women in Radiology in North America are still underrepresented. We reviewed the literature to highlight the current status of women in Radiology in North America, identify the underlying causes of the gender gap, and provide potential strategies to close this gap. We conducted a narrative literature review using the terms ("Gender Disparity" OR "Gender Inequality") AND ("Radiology Department" OR "Radiology Residency"), searching data from April 2000 to April 2022 in Ovid Medline, Embase, PubMed, and Scopus. Our results indicate that Radiology in North America lacks gender diversity in its subspecialties, academic leadership, and research productivity, which the COVID-19 pandemic has further exacerbated. Challenges stemming from a dearth of women role models, limited preclinical contact, and a high rate of burnout contribute to the current gender inequality. Several complementary and supplementary steps can enhance gender diversity in Radiology. These include increasing education and exposure to Radiology at earlier stages and optimizing mentorship opportunities to attract a more diverse pool of talent to the discipline. In addition, supporting resident parents and enhancing the residency program's culture can decrease the rate of burnout and encourage women to pursue careers and leadership positions in Radiology.

Sexual Medicine Society of North America (SMSNA)/American Urological Association (AUA) telemedicine and men's health white paper.

PURPOSE: The purpose of this white paper is to educate health care professionals about the evolution of telemedicine (TM) and to propose a hybrid model that leverages the strengths of traditional in-person medicine as well as virtual medicine while maximizing the safety and quality of men's sexual health care. LITERATURE SEARCH STRATEGY: A literature search focused on the use of TM in urology and men's health was performed through PubMed/MEDLINE, Embase, and Web of Science (January 1, 2012-April 26, 2022). Keywords included all known permutations of the terminology used to refer to virtual health, care as well as the terminology used to refer to urologic diseases, issues specific to men's health, and men's sexual health concerns. Publications that emerged after the literature search that met this criterion also were incorporated. Opinion pieces, letters to the editor, meeting abstracts, and conference proceedings were excluded. Additional resources were retrieved, such as governmental technical reports, legislative updates and reviews, and blogs. This search strategy yielded 1684 records across databases after removal of duplicates. Abstracts from the retrieved records were reviewed for relevance. Relevant publications were defined as those that reported data on any aspect of TM use specific to urology, men's health, and/or men's sexual health. If relevance was unclear from the abstract, then the full text of the article was retrieved for a more detailed review. In addition, the published evidence-based practice guidelines relevant to care for erectile dysfunction, Peyronie's disease, ejaculatory dysfunction, and hypogonadism were retrieved. The most common reasons for article exclusions were a focus on TM use in disciplines other than urology and the absence of data (ie, opinion pieces). After exclusions, a total of 91 publications remained and constituted the evidence base for this paper.
