Chemosensory deficiency may render island-dwelling lizards more vulnerable to invasive predators
Authors: Van Moorleghem Charlotte , Huyghe Katleen , Van Damme Raoul 
Published: September 2019

AbstractNewly introduced predators constitute a major threat to prey populations worldwide. Insular prey animals in particular often do not succeed in overcoming their naivety towards alien predators, making them specifically vulnerable. Why this is the case remains incompletely understood. Here, we investigate how the ability to detect and respond to predator chemical cues varies among populations of the Dalmatian wall lizard, Podarcis melisellensis. Lizards were sampled from five locations in south-eastern Croatia (one mainland location and four islands) that varied in the composition of their predator community. We observed the lizards’ behaviour in response to chemical cues of native saurophagous snakes (the Balkan whip snake, Hierophis gemonensis, and eastern Montpellier snake, Malpolon insignitus) and an introduced mammalian predator (the small Indian mongoose, Herpestes auropunctatus – a species held responsible for the loss of numerous insular reptile populations worldwide). Mainland lizards showed elevated tongue-flick rates (indicative of scent detection) as well as behaviours associated with distress in response to scents of both native and introduced predators. In sharp contrast, island lizards did not alter their behaviour when confronted with any of the predator cues. Alarmingly, even lizards from islands with native predators (both snakes and mammals) and from an island on which mongooses were introduced during the 1920s were non-responsive. This suggests that insular populations are chemosensorily deprived. As failure at the predator-detection level is often seen as the most damaging form of naivety, these results provide further insight into the mechanisms that render insular-living animals vulnerable to invasive species.
Searching for Virtue Ethics: A Survey of Social Work Ethics Curriculum and Educators
Authors: Pawar Manohar , Hugman Richard , Anscombe A W (Bill) , Alexandra Andrew 
Published: September 2019

Abstract
This article discusses whether, and to what extent, virtue ethics is covered in the social work ethics curriculum and views of social work ethics educators in Australia. Drawing on a survey of social work ethics curriculum and education, it presents the nature and scope of social work ethics subjects in terms of learning outcomes; overall curriculum content; textbooks used; teaching approaches, challenges and strategies for teaching; and social work ethics educators’ views about teaching virtue ethics. It argues that attention to virtues is largely absent in terms of consciously developing certain qualities and character. The findings, conclusions and implications of the study will be useful to social work researchers, educators and practitioners alike.
Gazing at “It”: An Intersectional Analysis of Transnormativity and Black Womanhood in Orange is the New Black
Authors: Thomas Victoria E 
Published: September 2019

Abstract
Transgender representations are predominantly negative and represent trans identities in dehumanizing tropes. I analyze the sole Black. transgender character on Orange is the New Black, Sophia Burset, to theorize a framework for transgender subjectivity that interrupts dehumanizing tropes. Sophia’s narrative on the show constructs transgender subjectivity through Sophia’s medical transformation, relationship with a Catholic nun, and lack of community with Black, cisgender women in prison. I employ theory from Black feminism and transgender media studies to analyze Sophia’s medical transition, interpersonal relationships, and political ideologies. Ultimately, Sophia Burset’s narrative functions as a non-threatening trans woman to alleviate transphobia and render Blackness invisible in Laverne Cox’s embodiment of Sophia Burset.
Plumage Convergence in Picoides Woodpeckers Based on a Molecular Phylogeny, With Emphasis on Convergence in Downy and Hairy Woodpeckers
Authors: Weibel Amy C. , Moore William S. 
Published: September 2019

AbstractAdult and juvenile plumage characters were traced onto a well-resolved molecular based phylogeny for Picoides woodpeckers, and a simple phylogenetic test of homology, parallelism, and convergence of plumage characters was performed. Reconstruction of ancestral character states revealed multiple events of independent evolution of derived character states in most characters studied, and a concentrated changes test revealed that some plumage characters evolved in association with habitat type. For example, there was a statistically significant association between loss of dorsal barring and use of densely vegetated habitats among Picoides species. Two analyses indicated that convergence, as opposed to parallel evolution or shared ancestry, underlies the similarity in plumage patterns between the Downy (Picoides pubescens) and Hairy (P. villosus) Woodpeckers. Possible causal explanations for convergence in plumage patterns may include mimicry and interspecific territoriality.
Estimating Shorebird Numbers at Migration Stopover Sites

Abstract

Abstract
We describe a method for estimating the totalnumber of shorebirds that use a migration stopoversite during spring and fall migration. We combinedweekly shorebird counts with parameter estimatesfor detection probability, sampled proportion, andlength of stay on the Squaw Creek National WildlifeRefuge. Double sampling was used to determinedetection probability and estimated values variedamong wetland units from a low of 0.07 to a high of0.82. The sampled proportion of most wetland unitswas 100% but was lower in some of the largerunits. Length of stay (measured for Pectoral[Calidrismelanotos] and LeastSandpipers [C.minutilla] combined)averaged 10.0 days in spring and3.7 days in fall. Spring shorebird numberswere approximately five times greater than fallnumbers on the Refuge. Annual shorebird numbersvaried among years from an estimated low in 2003 of15 734 to a high in 2002 of 69 570.Peak daily counts during study years averaged only12% of estimated spring totals and 4%of fall totals. An estimate of shorebird numbersbased on summing weekly counts, not corrected fordetection probability or sampled proportion, wouldhave been only 21% (spring) to31% (fall) of the total number ofbirds. These results reveal that peak counts andnonadjusted counts can significantly underestimatethe number of shorebirds that use migrationstopover sites in the midcontinent of NorthAmerica.
Differences in Plumulaceous Feather Characters of Dabbling and Diving Ducks
Authors: Dove Carla J , Agreda Ana 
Published: September 2019

AbstractAbstractWe examined variation in five microscopic plumulaceous (downy) feather characters of eighteen species of dabbling (Anatini) and diving (Aythyini, Mergini) ducks to quantify the differences between these tribes, and to explain how the plumulaceous feather ultrastructure in ducks may be influenced by different ecological requirements. Over 75% of the variation in feather characters among these ducks was explained by the first two components of a principal components analysis (PCA). Component 1 explained 51% of the variation and was positively correlated with the characters that quantified the number of barbules with expanded nodes and the number of expanded nodes on barbules. The microscopic feather characters of dabbling ducks (Anatini) have triangular-shaped, expanded nodes on most proximal barbules, whereas diving ducks (Aythyini and Mergini) lack expanded nodes on some barbules. Anatini also have a greater density of expanded nodes per barbule, wider nodes, shorter distance between expanded nodes, and longer barbule length. Further analysis of node density across all taxa showed that as dive depths increase, the number of expanded nodes per barbule decreases, and in the deepest divers many of the barbules completely lack expanded nodes. The significantly greater density of expanded nodes in dabbling ducks suggests that the downy nodes may function to trap more air. Diving species have fewer expanded nodes, less buoyant plumage, and are more efficient at foraging in deeper water than dabbling ducks.
A Reversed Pattern of Association Between Song Dialects and Habitat in the Rufous-Collared Sparrow
Authors: Lijtmaer Darío A. , Tubaro Pablo L. 
Published: September 2019

AbstractAbstract. We studied song dialects of the Rufous-collared Sparrow (Zonotrichia capensis) in espinal woodland and steppe surrounding Guatraché Lake in Argentina. We recorded 150 individuals and analyzed 14 quantitative song variables. There were significant differences between habitats in song temporal structure. In particular, the internote interval of trills was shorter in the closed compared to the open habitat. This pattern is the reverse of what is usually found in this species, although it has previously been detected in another area of the region in which this study was conducted. This region is characterized by strong winds, which could be related to the reversed pattern found. Song frequencies were lower in the closed woodland habitat than in the open steppe, which also contrasts with the pattern usually found in this species. We also recorded and analyzed the songs in a portion of the area in which the woodland was converted into grassland during the last century. The temporal structure of songs in the converted area was intermediate between song structures in the original habitats and frequencies were lower in the converted area than in both original habitats. Song structure appears to have changed after habitat conversion, but this cannot be confirmed with the data at hand because of the lack of recordings obtained before habitat change.
Isotopic Evidence for Sources of Nutrients Allocated to Clutch Formation by Harlequin Ducks
Authors: Bond Jeanine C. , Esler Daniel , Hobson Keith A. 
Published: September 2019

AbstractAbstract. Waterfowl employ a broad array of strategies for acquiring the energy and nutrients needed for egg formation, ranging from storage of endogenous reserves prior to arrival on breeding areas to complete reliance on exogenous food sources available at breeding sites. We used stable isotope analyses (δ13C and δ15N) to quantify the relative nutrient inputs to Harlequin Duck (Histrionicus histrionicus) eggs and, therefore, to identify the strategy of nutrient acquisition and allocation used by females to meet the demands of egg production. Marine-derived endogenous nutrients are isotopically more enriched than freshwater dietary nutrients for Harlequin Ducks that migrate between marine wintering grounds and terrestrial breeding grounds. There was little evidence that endogenous reserves stored on marine wintering areas were allocated to clutch formation. Therefore, Harlequin Ducks relied on food available in streams on breeding grounds for egg formation, and reserves stored on marine areas were likely used during other energetically and nutritionally demanding periods.

AbstractBackground and AimsA personalized approach to therapy hold great promise to improve disease outcomes. To this end, the identification of different subsets of patients according to the prevalent pathogenic process might guide the choice of therapeutic strategy. We hypothesize that ulcerative colitis [UC] patients might be stratified according to distinctive cytokine profiles and/or to a specific mucosa-associated microbiota.MethodsIn a cohort of clinically and endoscopic active UC patients and controls, we used quantitative PCR to analyse the mucosal cytokine mRNA content and 16S rRNA gene sequencing to assess the mucosa-associated microbiota composition.ResultsWe demonstrate, by means of data-driven approach, the existence of a specific UC patient subgroup characterized by elevated IL-13 mRNA tissue content separate from patients with low IL-13 mRNA tissue content. The two subsets differ in clinical–pathological characteristics. High IL-13 mRNA patients are younger at diagnosis and have a higher prevalence of extensive colitis than low IL-13 mRNA patients. They also show more frequent use of steroid/immunosuppressant/anti-tumour necrosis factor α therapy during 1 year of follow-up. The two subgroups show differential enrichment of mucosa-associated microbiota genera with a prevalence of Prevotella in patients with high IL-13 mRNA tissue content and Sutterella and Acidaminococcus in patients with low IL-13 mRNA tissue content.ConclusionAssessment of mucosal IL-13 mRNA might help in the identification of a patient subgroup that might benefit from a therapeutic approach modulating IL-13.PodcastThis article has an associated podcast which can be accessed at https://academic.oup.com/ecco-jcc/pages/podcast
Association of Insect-Derived Ear Injury With Yield and Aflatoxin of Maize Hybrids Varying in Bt Transgenes
Authors: Pruter Luke S , Brewer Michael J , Weaver Mark A , Murray Seth C , Isakeit Thomas S , Bernal Julio S 
Published: September 2019

Abstract
Environmental factors have been associated with the production of aflatoxin in maize, Zea mays L., and it is inconclusive whether transgenic, Bacillus thuringiensis (Bt), maize has an impact on aflatoxin accumulation. Maize hybrids differing in transgenes were planted in two locations from 2014 to 2017. Yield, aflatoxin, and ear injury caused by corn earworm, Helicoverpa zea (Boddie), and fall armyworm, Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae), were measured across three groups of hybrids differing in transgenes including near-isogenic hybrids, and water-stressed conditions. The hybrid groups consisted of non-Bt hybrids with no Bt transgenes, a second group with one or more Cry-Bt transgenes, and the third group with vegetative insecticidal Bt protein and Cry-Bt transgenes (Cry/Vip-Bt). Across the six data sets derived from 11 experiments, the Cry-Bt and Cry/Vip-Bt hybrids had less ear injury and aflatoxin on average than non-Bt hybrids. The effects of ear injury on yield and aflatoxin were more prominent and consistent in Corpus Christi, TX, where hybrids experienced more water-limited conditions than in College Station, TX. The trend of increased aflatoxin among hybrids with increased ear injury was further resolved when looking at Cry-Bt and Cry/Vip-Bt isogenic hybrids in Corpus Christi. The results supported that the maize hybrids with the inclusion of Cry-Bt and Cry/Vip-Bt transgenes warrant further investigation in an integrated approach to insect and aflatoxin management in sub-tropical rain-fed maize production regions. Research outcomes may be improved by focusing on areas prone to water-stress and by using hybrids with similar genetic backgrounds.
Bombus (Hymenoptera: Apidae) Microcolonies as a Tool for Biological Understanding and Pesticide Risk Assessment

Published: September 2019

Abstract
Bumble bees provide valuable pollination services to many wild and agricultural plants. Populations of some bumble bee species are in decline, prompting the need to better understand bumble bee biology and to develop methodologies for assessing the effects of environmental stressors on these bees. Use of bumble bee microcolonies as an experimental tool is steadily increasing. This review closely examines the microcolony model using peer-reviewed published literature identified by searching three databases through November 2018. Microcolonies have been successfully used for investigating a range of endpoints including behavior, the gut microbiome, nutrition, development, pathogens, chemical biology, and pesticides/xenobiotics. Methods for the initiation and monitoring of microcolonies, as well as the recorded variables were catalogued and described. From this information, we identified a series of recommendations for standardizing core elements of microcolony studies. Standardization is critical to establishing the foundation needed to support use of this model for biological response investigations and particularly for supporting use in pesticide risk assessment.
A comparison of UAV laser scanning, photogrammetry and airborne laser scanning for precision inventory of small-forest properties

Published: September 2019

AbstractThis study addresses the use of multiple sources of auxiliary data from unmanned aerial vehicles (UAVs) and airborne laser scanning (ALS) data for inference on key biophysical parameters in small forest properties (5–300 ha). We compared the precision of the estimates using plot data alone under a design-based inference with model-based estimates that include plot data and the following four types of auxiliary data: (1) terrain-independent variables from UAV photogrammetric data (UAV-SfM); (2) variables obtained from UAV photogrammetric data normalized using external terrain data (UAV-SfMDTM); (3) UAV-LS and (4) ALS data. The inclusion of remotely sensed data increased the precision of DB estimates by factors of 1.5–2.2. The optimal data sources for top height, stem density, basal area and total stem volume were: UAV-LS, UAV-SfM, UAV-SfMDTM and UAV-SfMDTM. We conclude that the use of UAV data can increase the precision of stand-level estimates even under intensive field sampling conditions.
After the Burden Is Lifted: Caregivers' Recovery of Life Satisfaction After the Death or Recovery of a Spouse
Authors: Langner Laura A , Furstenberg Frank F 
Published: September 2019

Abstract

Objective
How does caregivers' life satisfaction shift upon the recovery of an ill spouse? Paradoxically, there is a greater increase in life satisfaction upon death than recovery of a spouse. Our analysis explores this paradox.

Method
We follow the two groups of exiting caregivers longitudinally for 4 years from when the partner is still in need of care until the death (N = 152) or recovery (N = 112) of a previously ill partner, comparing their trajectory of life satisfaction. We use the years 2001–2016 of the German-Socio-Economic Panel Study and a growth curve analysis.

Results
Contrary to our expectations, bereaved caregivers experience a significantly stronger increase in life satisfaction than spouses whose partners recover from a serious illness, even when we stratify by age, gender and initial life satisfaction to account for significantly different subsample composition. Surprisingly, life satisfaction remains unchanged when the partner recovers. Only if a heavy burden in terms of unpaid care and housework hours or prior care need is lifted, do we observe an increase in life satisfaction among spouses with recovering partners, which is like the one experienced by bereaved caregivers.

Discussion
More support for caregivers with high caregiving burdens may alleviate some of the strain associated with spousal caregiving, as—even if the partner dies—a decrease in spousal caregiving hours results in an uplift in life satisfaction.

Abstract
There is some evidence that female sex workers (FSWs) receive greater earnings for providing unprotected sex. In 2003, the landscape of the fight against HIV/AIDS dramatically changed in India with the introduction of Avahan, the largest HIV prevention programme implemented globally. Using a unique, cross-sectional bio-behavioural dataset from 3591 FSWs located in the four Indian states where Avahan was implemented, we estimate the economic loss faced by FSWs who always use condoms. We estimate the causal effect of condom use on the price charged during the last paid sexual intercourse using the random targeting of Avahan as an instrumental variable. Results indicate that FSWs who always use condoms face an income loss of 65% (INR125, US$2.60) per sex act compared to peers providing unprotected sex, consistent with our expectations. The main finding confirms that clients have a preference for unprotected sex and that policies aiming at changing clients’ preferences and at improving the bargaining power of FSWs are required to limit the spread of HIV.
Thoracic endovascular aortic repair of an aberrant arterial aneurysm with pulmonary sequestration
Authors: Yamamoto Masaki , Okada Hironobu , Nakashima Junko , Anayama Takashi 
Published: September 2019

Abstract
We describe a treatment strategy for an aberrant arterial aneurysm associated with pulmonary sequestration. A 58-year-old man with impending aberrant arterial aneurysm rupture underwent a 2-stage surgery that included an emergency thoracic endovascular aortic repair (TEVAR) of the descending aorta to occlude the origin of the aberrant artery, followed by lobectomy. TEVAR can lead to faster occlusion of the aneurysm and can avoid operative risk of aneurysm rupture during lobectomy. The aberrant artery was broad where it branched off the aorta and had a short neck, rendering primary ligation or stump-forming unsuitable. Pathological findings revealed the fragility of the aberrant artery; thus, its root was prone to breakdown of the stump after simple aneurysmectomy. Furthermore, TEVAR may reduce graft infection during lobectomy in the second surgery. The 2-stage surgery may be useful for aberrant aneurysms complicated by pulmonary sequestration.
A Newton method for harmonic mappings in the plane
Authors: Sète Olivier , Zur Jan 
Published: September 2019

Abstract
We present an iterative root finding method for harmonic mappings in the complex plane, which is a generalization of Newton’s method for analytic functions. The complex formulation of the method allows an analysis in a complex variables spirit. For zeros close to poles of $f = h + \overline{g}$ we construct initial points for which the harmonic Newton iteration is guaranteed to converge. Moreover, we study the number of solutions of $f(z) = \eta $ close to the critical set of $f$ for certain $\eta \in \mathbb{C}$. We provide a MATLAB implementation of the method, and illustrate our results with several examples and numerical experiments, including phase plots and plots of the basins of attraction.
The Generalized Baker–Schmidt Problem on Hypersurfaces
Authors: Hussain Mumtaz , Schleischitz Johannes , Simmons David 
Published: September 2019

Abstract
The generalized Baker–Schmidt problem (1970) concerns the $f$-dimensional Hausdorff measure of the set of $\psi $-approximable points on a nondegenerate manifold. There are two variants of this problem concerning simultaneous and dual approximation. Beresnevich–Dickinson–Velani (in 2006, for the homogeneous setting) and Badziahin–Beresnevich–Velani (in 2013, for the inhomogeneous setting) proved the divergence part of this problem for dual approximation on arbitrary nondegenerate manifolds. The corresponding convergence counterpart represents a major challenging open question and the progress thus far has only been attained over planar curves. In this paper, we settle this problem for hypersurfaces in a more general setting, that is, for inhomogeneous approximations and with a non-monotonic multivariable approximating function.
