What are the causes and consequences of species diversity in forested ecosystems, and how is this species diversity being affected by rapid environmental and climatic change, movement of invertebrate ...and vertebrate herbivores into new biogeographic regions, and expanding human populations and associated shifts in land-use patterns? In this book, we explore these questions for assemblages of forest trees, shrubs, and understory herbs at spatial scales ranging from small plots to large forest dynamics plots, at temporal scales ranging from seasons to centuries, in both temperate and tropical regions, and across rural-to-urban gradients in land use.

Data regarding demographics, professional degree, training and current practice location, and perceptions regarding orthopedic surgery was obtained using Likert rating scales. Data was analyzed using descriptive statistics with two-tailed student's t-tests (α=0.05).The survey yielded 282 responses (182 females and 100 males). Overall, the distribution of residents (28%), fellows (6%), and attendings (66%) correlates well with the prevalence of each respective physician category in the field of orthopedic surgery. The study demonstrated no difference in subspecialty choice based on mentorship, work-life-balance, career advancement, subspecialty culture, salary potential, family planning, or schedule. However, a statistically significant difference exists regarding stereotypes, perceived strength required, and perception of discrimination from pursuing a specific orthopedic subspecialty. 27% of females and 10% of males reported discouragement from any subspecialty (p<0.05). Adult reconstructive and oncology were most frequently discouraged. Women reported not choosing a subspecialty because of perceived physical demands more often than men (p<0.001). Women reported an increased use of adaptive strategies in the operating room (p<0.001). Women were also more likely to report feeling discouraged from pursuing a subspecialty due to their gender (p<0.001). Both men and women reported mentorship as the most influential factor in subspecialty selection.ResultsThe survey yielded 282 responses (182 females and 100 males).

Hill numbers or the effective number of species are increasingly used to quantify species diversity of an assemblage. Hill numbers were recently extended to phylogenetic diversity, which incorporates ...species evolutionary history, as well as to functional diversity, which considers the differences among species traits. We review these extensions and integrate them into a framework of attribute diversity (the effective number of entities or total attribute value) based on Hill numbers of taxonomic entities (species), phylogenetic entities (branches of unit-length), or functional entities (species-pairs with unit-distance between species). This framework unifies ecologists' measures of species diversity, phylogenetic diversity, and distance-based functional diversity. It also provides a unified method of decomposing these diversities and constructing normalized taxonomic, phylogenetic, and functional similarity and differentiation measures, including
N
-assemblage phylogenetic or functional generalizations of the classic Jaccard, Sørensen, Horn, and Morisita-Horn indexes. A real example shows how this framework extracts ecological meaning from complex data.
Equal opportunity in the workplace is thought to be the direct legacy of the civil rights and feminist movements and the landmark Civil Rights Act of 1964. Yet, as Frank Dobbin demonstrates, ...corporate personnel experts--not Congress or the courts--were the ones who determined what equal opportunity meant in practice, designing changes in how employers hire, promote, and fire workers, and ultimately defining what discrimination is, and is not, in the American imagination. Dobbin shows how Congress and the courts merely endorsed programs devised by corporate personnel. He traces how the first measures were adopted by military contractors worried that the Kennedy administration would cancel their contracts if they didn't take "affirmative action" to end discrimination. These measures built on existing personnel programs, many designed to prevent bias against unionists. Dobbin follows the changes in the law as personnel experts invented one wave after another of equal opportunity programs. He examines how corporate personnel formalized hiring and promotion practices in the 1970s to eradicate bias by managers; how in the 1980s they answered Ronald Reagan's threat to end affirmative action by recasting their efforts as diversity-management programs; and how the growing presence of women in the newly named human resources profession has contributed to a focus on sexual harassment and work/life issues.
In a stimulating interchange between feminist studies and biology, Banu Subramaniam explores how her dissertation on flower color variation in morning glories launched her on an intellectual odyssey ...that engaged the feminist studies of sciences in the experimental practices of science by tracing the central and critical idea of variation in biology. As she shows, the histories of eugenics and genetics and their impact on the metaphorical understandings of difference and diversity that permeate common understandings of differences among people exist in contexts that seem distant from the so-called objective hard sciences. Journeying into areas that range from the social history of plants to speculative fiction, Subramaniam uncovers key relationships between the life sciences, women's studies, evolutionary and invasive biology, and the history of ecology, and how ideas of diversity and difference emerged and persist in each field.
The Ruth Jackson Orthopaedic Society awards the Jacquelin Perry, MD Resident Research Grant and RJOS/Zimmer Biomet Clinical/Basic Science Research Grant to female orthopedic surgeons, intending to ...aid women in the progression and completion of their orthopedic research and bolster their pursuit or current career in academic orthopedic surgery. The impact of these grants has not yet been studied. The purpose of this study is to determine the percentage of scholarship/grant-winners who went on to publish the findings of their research, pursue academic positions, and currently hold positions of leadership in the field of orthopedic surgery.
The titles of the winning research projects were searched in PubMed, Embase, and/or Web of Science to ascertain publication status. For each award recipient, the number of publications prior to the award year, number of publications after the award year, total number of publications, and H-index were calculated. Each award recipient was searched online through the websites of their employment and social media pages to determine their residency institution, whether they pursued a fellowship, the number of fellowships they pursued, their subspecialty within orthopedics, their current job, and whether they are in academic or private practice.
Of the fifteen Jacquelin Perry, MD Resident Research Grant winners, 73.3% of awarded research projects have since been published. 76.9% of award winners currently work in an academic setting and are affiliated with a residency program, and 0% currently hold leadership positions in orthopedic surgery. Of the eight winners of the RJOS/Zimmer Biomet Clinical/Basic Science Research Grant, 25% have published the findings of their awarded grant. 87.5% of award winners currently work in academics, and 75% hold leadership positions in orthopedic surgery.
Our results show that many of the winners of the Jacquelin Perry, MD Resident Research Grant and RJOS/Zimmer Biomet Clinical/ Basic Science Research Grant have published their research findings, continued research within the field of orthopedic surgery, and pursued academic careers and leadership positions. Many of the barriers to career progression and entry into orthopedic surgery that women and underrepresented groups face could be overcome through more grant opportunities and mentorship.

Diversity in orthopedics is lacking despite ongoing efforts to create a more inclusive workforce. Increasing diversity necessitates recruitment and retainment of underrepresented providers, which ...involves representation among leadership, mentorship initiatives, and development of a safe work environment. Discrimination and harassment behaviors are prevalent within orthopedics. Current initiatives aim to address these behaviors among peers and supervising physicians, but patients are an additional underrecognized source of these negative workplace behaviors. This report aims to establish the prevalence of patient-initiated discrimination and harassment within a single academic orthopedic department and establish methods to reduce these behaviors in the workplace.
An internet-based survey was designed using the Qualtrics platform. The survey was distributed to all employees of a single academic orthopedic department including nursing staff, clerks, advanced practice providers, research staff, residents/fellows, and staff physicians. Survey was distributed on two occasions between May and June of 2021. The survey collected information on respondent demographics, experience with patient-initiated discrimination/harassment, and opinions regarding possible intervention methods. Fisher exact test was used for statistical analysis.
Over one half of survey respondents report observing or personally experiencing patient-initiated discrimination within our orthopedics department (57%, n=110). Nearly half of respondents report observing or personally experiencing patient-initiated harassment within our department (46%, n=80). Encounters with these behaviors were more commonly reported from resident and staff female physicians. The most frequently reported negative patient-initiated behaviors include gender discrimination and sexual harassment. Discordance exists regarding optimal methods to address these behaviors, but one third of respondents indicate potential benefit from visual aids throughout the department.
Discrimination and harassment behaviors is common within orthopedics, and patients are a significant source of this negative workplace behavior. Identification of this subset of negative behaviors will allow us to provide patient education and provider response tools for the protection of orthopedic staff members. Ideally, minimizing discrimination/harassment behaviors within our field will help create a more inclusive workplace environment and allow continued recruitment of diverse candidates into our field.

Access to orthopaedic care across the United States (U.S.) remains an important issue, however, no recent study has examined disparities in rural access to orthopaedic care. The goals of the present ...study were to (1) investigate trends in the proportion of rural orthopaedic surgeons from 2013 to 2018 as well as the proportion of rural U.S. counties with access to such surgeons and (2) analyze characteristics associated with choice of a rural practice setting.
The study analyzed the Centers for Medicare and Medicaid Services (CMS) Physician Compare National Downloadable File (PC-NDF) for all active orthopaedic surgeons from 2013 to 2018. Rural practice settings were defined using Rural-Urban Commuting Area (RUCA) codes. Linear regression analysis investigated trends in rural orthopaedic surgeon volume. Multivariable logistic regression evaluated the association of surgeon characteristics with rural practice setting.
The total number of orthopaedic surgeons increased 1.9%, from 21,045 (2013) to 21,456 (2018). Meanwhile, the proportion of rural orthopaedic surgeons decreased by roughly 0.9%, from 578 (2013) to 559 (2018). From a per capita perspective, the number of orthopaedic surgeons practicing in a rural setting per 100,000 population ranged from 4.55 orthopaedic surgeons per 100,000 in 2013 and 4.47 per 100,000 in 2018. Meanwhile, the number of orthopaedic surgeons practicing in an urban setting ranged from 6.63 per 100,000 in 2013 and 6.35 per 100,000 in 2018. The surgeon characteristics most associated with decreased odds of practicing orthopaedic surgery in a rural setting included earlier career-stage (OR: 0.80, 95% CI: 0.70-0.91; p < 0.001) and sub-specialization status (OR: 0.40, 95% CI: 0.36-0.45; p < 0.001).
Existing rural-urban disparities in musculoskeletal healthcare access have persisted over the past decade and could worsen. Future research should investigate the effects of orthopaedic workforce shortages on travel times, patient cost burden, and disease specific outcomes.

ABSTRACT
Disturbances alter biodiversity via their specific characteristics, including severity and extent in the landscape, which act at different temporal and spatial scales. Biodiversity response ...to disturbance also depends on the community characteristics and habitat requirements of species. Untangling the mechanistic interplay of these factors has guided disturbance ecology for decades, generating mixed scientific evidence of biodiversity responses to disturbance. Understanding the impact of natural disturbances on biodiversity is increasingly important due to human‐induced changes in natural disturbance regimes. In many areas, major natural forest disturbances, such as wildfires, windstorms, and insect outbreaks, are becoming more frequent, intense, severe, and widespread due to climate change and land‐use change. Conversely, the suppression of natural disturbances threatens disturbance‐dependent biota. Using a meta‐analytic approach, we analysed a global data set (with most sampling concentrated in temperate and boreal secondary forests) of species assemblages of 26 taxonomic groups, including plants, animals, and fungi collected from forests affected by wildfires, windstorms, and insect outbreaks. The overall effect of natural disturbances on α‐diversity did not differ significantly from zero, but some taxonomic groups responded positively to disturbance, while others tended to respond negatively. Disturbance was beneficial for taxonomic groups preferring conditions associated with open canopies (e.g. hymenopterans and hoverflies), whereas ground‐dwelling groups and/or groups typically associated with shady conditions (e.g. epigeic lichens and mycorrhizal fungi) were more likely to be negatively impacted by disturbance. Across all taxonomic groups, the highest α‐diversity in disturbed forest patches occurred under moderate disturbance severity, i.e. with approximately 55% of trees killed by disturbance. We further extended our meta‐analysis by applying a unified diversity concept based on Hill numbers to estimate α‐diversity changes in different taxonomic groups across a gradient of disturbance severity measured at the stand scale and incorporating other disturbance features. We found that disturbance severity negatively affected diversity for Hill number q = 0 but not for q = 1 and q = 2, indicating that diversity–disturbance relationships are shaped by species relative abundances. Our synthesis of α‐diversity was extended by a synthesis of disturbance‐induced change in species assemblages, and revealed that disturbance changes the β‐diversity of multiple taxonomic groups, including some groups that were not affected at the α‐diversity level (birds and woody plants). Finally, we used mixed rarefaction/extrapolation to estimate biodiversity change as a function of the proportion of forests that were disturbed, i.e. the disturbance extent measured at the landscape scale. The comparison of intact and naturally disturbed forests revealed that both types of forests provide habitat for unique species assemblages, whereas species diversity in the mixture of disturbed and undisturbed forests peaked at intermediate values of disturbance extent in the simulated landscape. Hence, the relationship between α‐diversity and disturbance severity in disturbed forest stands was strikingly similar to the relationship between species richness and disturbance extent in a landscape consisting of both disturbed and undisturbed forest habitats. This result suggests that both moderate disturbance severity and moderate disturbance extent support the highest levels of biodiversity in contemporary forest landscapes.
