Abstract
Many shark populations are in decline around the world, with severe ecological and economic consequences. Fisheries management and marine protected areas (MPAs) have both been heralded as solutions. However, the effectiveness of MPAs alone is questionable, particularly for globally threatened sharks and rays ('elasmobranchs'), with little known about how fisheries management and MPAs interact to conserve these species. Here we use a dedicated global survey of coral reef elasmobranchs to assess 66 fully protected areas embedded within a range of fisheries management regimes across 36 countries. We show that conservation benefits were primarily for reef-associated sharks, which were twice as abundant in fully protected areas compared with areas open to fishing. Conservation benefits were greatest in large protected areas that incorporate distinct reefs. However, the same benefits were not evident for rays or wide-ranging sharks that are both economically and ecologically important while also threatened with extinction. We show that conservation benefits from fully protected areas are close to doubled when embedded within areas of effective fisheries management, highlighting the importance of a mixed management approach of both effective fisheries management and well-designed fully protected areas to conserve tropical elasmobranch assemblages globally.

Abstract
A global survey of coral reefs reveals that overfishing is driving resident shark species toward extinction, causing diversity deficits in reef elasmobranch (shark and ray) assemblages. Our species-level analysis revealed global declines of 60 to 73% for five common resident reef shark species and that individual shark species were not detected at 34 to 47% of surveyed reefs. As reefs become more shark-depleted, rays begin to dominate assemblages. Shark-dominated assemblages persist in wealthy nations with strong governance and in highly protected areas, whereas poverty, weak governance, and a lack of shark management are associated with depauperate assemblages mainly composed of rays. Without action to address these diversity deficits, loss of ecological function and ecosystem services will increasingly affect human communities.

Abstract
Both sharks and humans present a potentially lethal threat to mesopredatory fishes in coral reef systems, with implications for both population dynamics and the role of mesopredatory fishes in reef ecosystems. This study quantifies the antipredator behaviours mesopredatory fishes exhibit towards the presence of large coral reef carnivores and compares these behavioural responses to those elicited by the presence of snorkelers. Here, we used snorkelers and animated life-size models of the blacktip reef shark (Carcharhinus melanopterus) to simulate potential predatory threats to mesopredatory reef fishes (lethrinids, lutjanids, haemulids and serranids). The responses of these reef fishes to the models and the snorkelers were compared to those generated by three non-threatening controls (life-size models of a green turtle [Chelonia mydas], a PVC-pipe [an object control] and a Perspex shape [a second object control]). A Remote Underwater Stereo-Video System (Stereo-RUV) recorded the approach of the different treatments and controls and allowed accurate measurement of Flight Initiation Distance (FID) and categorization of the type of flight response by fishes. We found that mesopredatory reef fishes had greater FIDs in response to the approach of threatening models (1402 ± 402-1533 ± 171 mm; mean ± SE) compared to the controls (706 ± 151-896 ± 8963 mm). There was no significant difference in FID of mesopredatory fishes between the shark model and the snorkeler, suggesting that these treatments provoked similar levels of predator avoidance behaviour. This has implications for researchers monitoring behaviour in situ or using underwater census as a technique to estimate the abundance of reef fishes. Our study suggests that, irrespective of the degree to which sharks actually consume these mesopredatory reef fishes, they still elicit a predictable and consistent antipredator response that has the potential to create risk effects.

Abstract
Shark depredation is a complex social-ecological issue that affects a range of fisheries worldwide. Increasing concern about the impacts of shark depredation, and how it intersects with the broader context of fisheries management, has driven recent research in this area, especially in Australia and the United States. This review synthesises these recent advances and provides strategic guidance for researchers aiming to characterise the occurrence of depredation, identify the shark species responsible, and test deterrent and management approaches to reduce its impacts. Specifically, the review covers the application of social science approaches, as well as advances in video camera and genetic methods for identifying depredating species. The practicalities and considerations for testing magnetic, electrical, and acoustic deterrent devices are discussed in light of recent research. Key concepts for the management of shark depredation are reviewed, with recommendations made to guide future research and policy development. Specific management responses to address shark depredation are lacking, and this review emphasizes that a "silver bullet" approach for mitigating depredation does not yet exist. Rather, future efforts to manage shark depredation must rely on a diverse range of integrated approaches involving those in the fishery (fishers, scientists and fishery managers), social scientists, educators, and other stakeholders.

Abstract
Understanding the extent to which species' traits mediate patterns of community assembly is key to predict the effect of natural and anthropogenic disturbances on ecosystem functioning. Here, we apply a trait-based community assembly framework to understand how four different habitat configurations (kelp forests, Sargassum spp. beds, hard corals, and turfs) shape the trophic and energetic dynamics of reef fish assemblages in a tropical-temperate transition zone. Specifically, we tested (i) the degree of trait divergence and convergence in each habitat, (ii) which traits explained variation in species' abundances, and (iii) differences in standing biomass (kg ha-1), secondary productivity (kg ha-1 day-1) and turnover (% day-1). Fish assemblages in coral and kelp habitats displayed greater evidence of trait convergence, while turf and Sargassum spp. habitats displayed a higher degree of trait divergence, a pattern that was mostly driven by traits related to resource use and thermal affinity. This filtering effect had an imprint on the trophic and energetic dynamics of reef fishes, with turf habitats supporting higher fish biomass and productivity. However, these gains were strongly dependent on trophic guild, with herbivores/detritivores disproportionately contributing to among-habitat differences. Despite these perceived overall gains, turnover was decoupled for fishes that act as conduit of energy to higher trophic levels (i.e. microinvertivores), with coral habitats displaying higher rates of fish biomass replenishment than turf despite their lower productivity. This has important implications for biodiversity conservation and fisheries management, questioning the long-term sustainability of ecological processes and fisheries yields in increasingly altered marine habitats.

Abstract
Extreme climatic events can reshape the functional structure of ecological communities, potentially altering ecological interactions and ecosystem functioning. While these shifts have been widely documented, evidence of their persistence and potential flow-on effects on ecosystem structure following relaxation of extreme events remains limited. Here, we investigate changes in the functional trait structure - encompassing dimensions of resource use, thermal affinity, and body size - of herbivorous fishes in a temperate reef system that experienced an extreme marine heatwave (MHW) and subsequent return to cool conditions. We quantify how changes in the trait structure modified the nature and intensity of herbivory-related functions (macroalgae, turf, and sediment removal), and explored the potential flow-on effects on the recovery dynamics of macroalgal foundation species. The trait structure of the herbivorous fish assemblage shifted as a result of the MHW, from dominance of cool-water browsing species to increased evenness in the distribution of abundance among temperate and tropical guilds supporting novel herbivory roles (i.e. scraping, cropping, and sediment sucking). Despite the abundance of tropical herbivorous fishes and intensity of herbivory-related functions declined following a period of cooling after the MHW, the underlying trait structure displayed limited recovery. Concomitantly, algal assemblages displayed a lack of recovery of the formerly dominant foundational species, the kelp Ecklonia radiata, transitioning to an alternative state dominated by turf and Sargassum spp. Our study demonstrates a legacy effect of an extreme MHW and exemplified the value of monitoring phenotypic (trait mediated) changes in the nature of core ecosystem processes to predict and adapt to the future configurations of changing reef ecosystems.

Abstract
AIM OF THE STUDY The objective of this study was to evaluate the potential impact of a third wave CBT group intervention for the management of auditory hallucinations in patients with schizophrenia. METHOD 38 patients with schizophrenia presenting with auditory hallucinations, followed in mental health services, participated in six sessions of a group based on acceptance and engagement therapy (ACT). The study followed a repeated single case experimental design (type A-B-A) based on the principle of a control phase followed by an intervention phase and a follow-up phase of similar duration. The various measurements were administered during the control phase, at pre-/post-group and six weeks after the last group session. RESULTS The results show a significant decrease in auditory hallucinations, as measured by the PSYRATS scale, during the treatment and follow-up phase, compared to the control phase. In addition, the participants saw significant reductions in depressive and anxious symptomatology (assessed with CDSS and SEAS), and increases in coping and acceptance in regards to voices (assessed using a study scale and VAAS). The level of Malevolence beliefs about voices (measured with BAVQ-R) also decreased significantly. CONCLUSIONS A brief group intervention based acceptance show promise in the reduction of the intensity of auditory hallucinations, depression and anxiety in patients with schizophrenia, while improving their acceptance.

Abstract
Decades of overexploitation have devastated shark populations, leaving considerable doubt as to their ecological status1,2. Yet much of what is known about sharks has been inferred from catch records in industrial fisheries, whereas far less information is available about sharks that live in coastal habitats3. Here we address this knowledge gap using data from more than 15,000 standardized baited remote underwater video stations that were deployed on 371 reefs in 58 nations to estimate the conservation status of reef sharks globally. Our results reveal the profound impact that fishing has had on reef shark populations: we observed no sharks on almost 20% of the surveyed reefs. Reef sharks were almost completely absent from reefs in several nations, and shark depletion was strongly related to socio-economic conditions such as the size and proximity of the nearest market, poor governance and the density of the human population. However, opportunities for the conservation of reef sharks remain: shark sanctuaries, closed areas, catch limits and an absence of gillnets and longlines were associated with a substantially higher relative abundance of reef sharks. These results reveal several policy pathways for the restoration and management of reef shark populations, from direct top-down management of fishing to indirect improvement of governance conditions. Reef shark populations will only have a high chance of recovery by engaging key socio-economic aspects of tropical fisheries.

Abstract
OBJECTIVES Hearing voices is a common experience for people with schizophrenia. Perceived voices are in most cases a source of great distress for patients. This experience also exists in the general population and is considered as "non-clinical". Much research has focused on the psychological and neuropsychological mechanisms behind the emergence of voices. With regard to voice persistence factors, the acceptance of the voice-hearing phenomenon is still relatively unexplored. In addition, there are few standardized tools that specifically assess this dimension of voice experience. The Voices Acceptance and Actions Scale (VAAS) is the only validated tool to address voice acceptance in individuals with schizophrenia. However, to date, there is no French version. The objective of this research was to validate the VAAS in a French speaking population. METHOD Our sample consisted of individuals with schizophrenia (N=65) and voice hearers from the general population (N=321). For the clinical population, individuals with schizophrenia and auditory hallucinations were assessed using the VAAS scale in its two abbreviated versions (9 and 12 items). In order to validate the measure in French, we administered psychopathology scales (BPRS) and voice belief scales (BAVQ-R) for convergent and divergent validity. For the non-clinical population, we administered the VAAS scale online (via LimeSurvey), accompanied by a brief sociodemographic questionnaire (age, sex, country of origin, existence of medical or psychological follow-up). RESULTS The psychometric properties of the VAAS scale were satisfactory and similar to the original English-language tool for both versions, with a slight advantage for the one with 9-items. The convergent validity measured with the BAVQ-R scale, and the divergent one measured with the BPRS depression subscale, were found to be satisfactory. In addition, the re-test performed 6 weeks after the first test (N=30) was satisfactory for both scales, with a Pearson correlation index greater than 70 (r=0.70; P<0.001 for the VAAS 9 items) and (r=0.79; P<0.001 for the 12 item version). In individuals with schizophrenia (clinical population), the level of voice acceptance was low and strongly correlated with depression. This point seems to corroborate the current data in the field suggesting that voice hearing in this population is associated with significant distress and has a significant impact on their lives. Conversely, the level of acceptance obtained from the non-clinical population was much higher, reflecting a higher level of acceptance in this population. People from the non-clinical population seemed to accept and experience their voices with less distress than people from the clinical population in this study. CONCLUSION To date, a paucity of studies have investigated the acceptance of auditory hallucinations. Our results support the psychometric validity of the French version of the VAAS, particularly the 9-item version. Furthermore, our study supports the need to continue studying voice acceptance, as it appears to be strongly linked to depression in people with psychiatric disorders such as schizophrenia. In addition, our study is novel in that it also explored, with a standardized tool, the level of voice acceptance in a non-clinical population and found people to be more accepting of the voices they hear and better at living with them. These data provide new evidence to better understand the links between the level of acceptance of voices, their experiences, and depression. Clinically, it seems essential to conduct more systematic and regular evaluations of the level of voice acceptance in those hearing voices. Finally, in terms of rehabilitation, voice acceptance can become a therapeutic target in order to improve the psychological and behavioral functioning of the person.

Abstract
Animal bite wounds are amongst the most common types of traumatic injuries in humans. The organisms isolated from these wounds generally reflect the oral flora of the biting animal and may be fastidious in nature and difficult to identify. This study was undertaken to determine the prevalence of Eikenella corrodens, Actinobacillus actinomycetemcomitans, Porphyromonas and Prevotella spp. in supragingival dental plaque collected from the right maxillary canine and carnassial teeth and the right mandibular canine tooth of dogs. In part one of the study, 30 dogs were used. E. corrodens was found in 62% of these dogs and 44% of individual plaque samples. A. actinomycetemcomitans was not detected in any of the dogs sampled. In pan two, 34 dogs were used to determine the prevalence of the black pigmented anaerobic bacilli (Porphyromonas and Prevotella spp.). Porphyromonas gingivalis was present in 68% of these dogs and 47% of individual plaque samples. Prevotella intermedia was present in 44% of the dogs and 23% of individual plaque samples. The recently described Porphyromonas canoris, Porphyromonas salivosa, Porphyromonas cangingivalis, Porphyromonas cansulci, Porphyromonas crevioricanis and Prevotella denticola species were isolated from only 9%, 6%, 3%, 3%, 3% and 3% of dogs respectively. Porphyromonas gingivicanis was not isolated from any of the animals sampled. In conclusion, black-pigmented anaerobic bacilli were isolated from 91% of the animals sampled and therefore constitute a significant risk with respect to bite wound infections. It is also suggested that the prevalence of E. corrodens in wound infections has been underestimated in previous reports because of use of inappropriate techniques for detecting this organism.

Abstract
No-take marine reserves (NTRs), i.e. areas with total fishing restrictions, have been established worldwide aiming to promote biodiversity and ecosystem conservation. Brazil has 3.3% of its exclusive economic zone protected by 73 different NTRs, however, most of them currently lack scientific knowledge and understanding of their ecological role, particularly regarding rocky reefs in subtropical regions. In this context, this study aimed to contrast a network of NTRs with comparable fished sites across a coastal biogeographic gradient to investigate the effect of fishing and habitat variability on the abundance and body size of rocky reef fish. We used Baited Remote Underwater stereo-Video (stereo-BRUVs) and Diver Operated stereo-Video (stereo-DOVs) systems to simultaneously sample reef fish and habitat. Model selection and results identified habitat and biogeographic variables, such as distance from shore, as important predictor variables, explaining several aspects of the fish assemblage. The effect of protection was important in determining the abundance and body size of targeted species, in particular for epinephelids and carangids. Conversely, species richness was correlated with habitat complexity but not with protection status. This is the first study using these survey methods in the Southwestern Atlantic, demonstrating how a network of NTRs can provide benchmarks for biodiversity conservation and fisheries management.

Abstract
Designated large-scale marine protected areas (LSMPAs, 100,000 or more square kilometers) constitute over two-thirds of the approximately 6.6% of the ocean and approximately 14.5% of the exclusive economic zones within marine protected areas. Although LSMPAs have received support among scientists and conservation bodies for wilderness protection, regional ecological connectivity, and improving resilience to climate change, there are also concerns. We identified 10 common criticisms of LSMPAs along three themes: (1) placement, governance, and management; (2) political expediency; and (3) social-ecological value and cost. Through critical evaluation of scientific evidence, we discuss the value, achievements, challenges, and potential of LSMPAs in these arenas. We conclude that although some criticisms are valid and need addressing, none pertain exclusively to LSMPAs, and many involve challenges ubiquitous in management. We argue that LSMPAs are an important component of a diversified management portfolio that tempers potential losses, hedges against uncertainty, and enhances the probability of achieving sustainably managed oceans.

Abstract
Climate-driven changes in biotic interactions can profoundly alter ecological communities, particularly when they impact foundation species. In marine systems, changes in herbivory and the consequent loss of dominant habitat forming species can result in dramatic community phase shifts, such as from coral to macroalgal dominance when tropical fish herbivory decreases, and from algal forests to 'barrens' when temperate urchin grazing increases. Here, we propose a novel phase-shift away from macroalgal dominance caused by tropical herbivores extending their range into temperate regions. We argue that this phase shift is facilitated by poleward-flowing boundary currents that are creating ocean warming hotspots around the globe, enabling the range expansion of tropical species and increasing their grazing rates in temperate areas. Overgrazing of temperate macroalgae by tropical herbivorous fishes has already occurred in Japan and the Mediterranean. Emerging evidence suggests similar phenomena are occurring in other temperate regions, with increasing occurrence of tropical fishes on temperate reefs.

Abstract
BACKGROUND The molecular bases of the cellular changes that occur during human megakaryocyte (MK) ontogeny remain unknown, and may be important for understanding the significance of MK differentiation from human embryonic stem cells (hESCs) METHODS We optimized the differentiation of MKs from hESCs, and compared these with MKs obtained from primary human hematopoietic tissues at different stages of development. RESULTS Transcriptome analyses revealed a close relationship between hESC-derived and fetal liver-derived MKs, and between neonate-derived and adult-derived MKs. Major changes in the expression profiles of cell cycle and transcription factors (TFs), including MYC and LIN28b, and MK-specific regulators indicated that MK maturation progresses during ontogeny towards an increase in MK ploidy and a platelet-forming function. Important genes, including CXCR4, were regulated by an on-off mechanism during development. DISCUSSION Our analysis of the pattern of TF network and signaling pathways was consistent with a growing specialization of MKs towards hemostasis during ontogeny, and support the idea that MKs derived from hESCs reflect primitive hematopoiesis.

Abstract
Breast cancer mortality rates have declined in the United States and in Wisconsin. We examined racial differences in mortality trends among black and white women in Wisconsin and the United States from 1979 to 1996. During this time period, mortality rates increased 10% among black women and decreased 7% among white women in Wisconsin. These trends were similar nationally, with an 18% increase among black women and a 3% decrease among white women. The black:white gap in mortality increased among women of all ages--especially among women under age 55. The increasing racial disparity in breast cancer mortality may result from differences in trends in incidence and survival among black women. More research is needed to understand the underlying causes of the disparity in breast cancer mortality between black and white women.

Abstract
Animal bite wounds are amongst the most common types of traumatic injuries in humans. The organisms isolated from these wounds generally reflect the oral flora of the biting animal, and may be fastidious in nature and difficult to identify. This study was undertaken to determine the prevalence of Eikenella corrodens, Actinobacillus actinomycetemcomitans, Porphyromonas and Prevotella spp. in supragingival dental plaque collected from the right maxillary canine and carnassial teeth and the right mandibular canine tooth of dogs. In part one of the study, 30 dogs were used. E. corrodens was found in 62% of these dogs and 44% of individual plaque samples. A. actinomycetemcomitans was not detected in any of the dogs sampled. In part two, 34 dogs were used to determine the prevalence of the black pigmented anaerobic bacilli (Porphyromonas and Prevotella spp.). Porphyromonas gingivalis was present in 68% of these dogs and 47% of individual plaque samples. Prevotella intermedia was present in 44% of the dogs and 23% of individual plaque samples. The recently described Porphyromonas canoris, Porphyromonas salivosa, Porphyromonas cangingivalis, Porphyromonas cansulci, Porphyromonas crevioricanis and Prevotella denticola species were isolated from only 9%, 6%, 3%, 3%, 3% and 3% of dogs respectively. Porphyromonas gingivicanis was not isolated from any of the animals sampled. In conclusion, black-pigmented anaerobic bacilli were isolated from 91% of the animals sampled and therefore constitute a significant risk with respect to bite wound infections. It is also suggested that the prevalence of E. corrodens in wound infections has been underestimated in previous reports because of use of inappropriate techniques for detecting this organism.

Abstract
The prevalence and populations of Eikenella corrodens, Actinobacillus actinomycetemcomitans and black pigmented anaerobic bacilli were determined in three samples of supragingival plaque from each of 30 healthy dogs. E corrodens was present in 62 per cent of the dogs and 43.7 per cent of the individual plaque samples but none of the dogs yielded A actinomycetemcomitans. Black pigmented anaerobic bacilli were present in 46.7 per cent of the dogs and 36.7 per cent of the individual plaque samples, and their numbers were correlated with the age of the dogs (P < 0.05) and the amount of plaque (P < 0.01). It is suggested that the prevalence of E corrodens in wound infections of man from dog bites has been underestimated from lack of appropriate techniques for detecting this fastidious organism.

Abstract
This study compared PCR and an assay for cytomegalovirus (CMV) pp65 antigenemia (CMV-vue; INCSTAR Corp.) with a quantitative shell vial culture (QSVC) technique for the detection of CMV in serial blood specimens from 46 solid-organ transplant recipients. In a comparison based on 535 specimens tested by PCR and QSVC, CMV was detected by PCR in 41 and by QSVC in 37 of 43 recipients at risk of CMV infection. The mean number of days after transplantation of initial detection of CMV was 29.9 for PCR and 34.0 for QSVC (P = 0.01). The antigenemia assay was performed on 395 specimens, including 304 of those also tested by PCR. In these specimens, CMV was detected by the antigenemia assay, QSVC, and PCR in 30, 32, and 35 (respectively) of 38 patients at risk, with no statistically significant difference in the time to detection. Each of the assays detected CMV in similar proportions of patients with and without clinically significant CMV infection. PCR stayed positive longer after transplantation than the other assays but frequently returned to negative when more than 6 months had elapsed after transplantation. The antigenemia assay and PCR stayed positive longer after institution of antiviral therapy than QSVC. PCR can provide highly sensitive detection of CMV viremia, but a PCR assay for CMV is not yet available in kit form. The pp65 antigenemia assay and shell vial culture are quantifiable and comparable in sensitivity. Either is recommended for rapid detection of CMV in blood specimens from solid-organ transplant recipients.

Abstract
A quantitative modification of the shell vial assay was used to investigate cytomegalovirus viremia in solid-organ transplant recipients. The level of viremia detected in 109 of 407 specimens ranged from 0.02 to 28 infectious foci per 100,000 leukocytes. By using a Poisson model, a technique was developed to determine 95% confidence limits for the measured levels of viremia. These confidence limits were used to determine the level of viremia that could be excluded by culturing a given number of cells. Longitudinal assessment of two transplant recipients revealed different patterns of viremia and demonstrated that significant disease sometimes occurred with low-level viremia. On the basis of the results of the studies, culture of at least 4 x 10(6) leukocytes is recommended for the sensitive detection of cytomegalovirus viremia.
