Identity in non-Western contexts ,Identity in the Caribbean ,Multidisciplinary perspective of conceptualizing identity ,Identity development in Central and South America ,Identity in Sub-Saharan Africa ,Identity development in East Asia - Abstract
Identity is a construct strongly rooted and still predominantly studied in Western (or WEIRD; Western, educated, industrialized, rich, and democratic) contexts (e.g., North American and Western European). Only recently has there been more of a conscious effort to study identity in non-Western (or non-WEIRD) contexts. This edited volume investigates identity from primarily a non-Western perspective by studying non-Western contexts and non-Western, minority, or immigrant groups living in Western contexts. The contributions (a) examine different aspects of identity (e.g., personal identity, social identity, online identity) as either independent or interrelated constructs; (b) consider the associations of these constructs with aspects of intergroup relations, acculturative processes, and/or psychological well-being; (c) document the advancement in research on identity in underrepresented groups, contexts, and regions such as Africa, Asia, Eastern Europe, the Middle East, and South America; and (d) evaluate different approaches to the study of identity and the implications thereof. This book is intended for cultural or cross-cultural academics, practitioners, educators, social workers, postgraduate students, undergraduate students, and scholars interested in studying identity. It provides insight into how identity in non-Western groups and contexts may both be informed by and may inform Western theoretical perspectives.

© The Author(s), 2022. This article is distributed under the terms of the Creative Commons Attribution License. The definitive version was published in Dragone, N. B., Henley, J. B., Holland-Moritz, H., Diaz, M., Hogg, I. D., Lyons, W. B., Wall, D. H., Adams, B. J., & Fierer, N. Elevational constraints on the composition and genomic attributes of microbial communities in Antarctic soils. Msystems, 7(1), (2022): e01330-21, https://doi.org/10.1128/msystems.01330-21., The inland soils found on the Antarctic continent represent one of the more challenging environments for microbial life on Earth. Nevertheless, Antarctic soils harbor unique bacterial and archaeal (prokaryotic) communities able to cope with extremely cold and dry conditions. These communities are not homogeneous, and the taxonomic composition and functional capabilities (genomic attributes) of these communities across environmental gradients remain largely undetermined. We analyzed the prokaryotic communities in soil samples collected from across the Shackleton Glacier region of Antarctica by coupling quantitative PCR, marker gene amplicon sequencing, and shotgun metagenomic sequencing. We found that elevation was the dominant factor explaining differences in the structures of the soil prokaryotic communities, with the drier and saltier soils found at higher elevations harboring less diverse communities and unique assemblages of cooccurring taxa. The higher-elevation soil communities also had lower maximum potential growth rates (as inferred from metagenome-based estimates of codon usage bias) and an overrepresentation of genes associated with trace gas metabolism. Together, these results highlight the utility of assessing community shifts across pronounced environmental gradients to improve our understanding of the microbial diversity found in Antarctic soils and the strategies used by soil microbes to persist at the limits of habitability., Geospatial support for this work was provided by the Polar Geospatial Center under NSF-OPP awards 1043681 and 155969.

This chapter combines developments in the emotion literature with developments in cross-cultural methodology in order to formulate four recommendations that can bridge the gap between relativist and universalist views on cultural variation in emotion. We recommend that researchers (1) specify the emotions or facets of emotions they study, preferably using a multi-componential approach to assessing emotions; (2) check the equivalence across languages and cultures of the emotion vocabulary they use, either by existing data bases or by including the measurement of meaning in their design; (3) specify the level at which they compare emotions across cultures ranging from descriptions of culture-specific constructs to direct comparisons of mean scores, and apply adequate methods to demonstrate the level of comparability claimed; and (4) account for both similarities and differences when they formulate hypotheses, as well as when they interpret their data. These recommendations are illustrated with historical and contemporary cross-cultural emotion research.

- Abstract
Outlet glaciers that flow through the Transantarctic Mountains (TAM) experienced changes in ice thickness greater than other coastal regions of Antarctica during glacial maxima. As a result, ice-free areas that are currently exposed may have been covered by ice at various points during the Cenozoic, complicating our understanding of ecological succession in TAM soils. Our knowledge of glacial extent on small spatial scales is limited for the TAM, and studies of soil exposure duration and disturbance, in particular, are rare. We collected surface soil samples and, in some places, depth profiles every 5 cm to refusal (up to 30 cm) from 11 ice-free areas along Shackleton Glacier, a major outlet glacier of the East Antarctic Ice Sheet. We explored the relationship between meteoric 10Be and NO3- in these soils as a tool for understanding landscape disturbance and wetting history and as exposure proxies. Concentrations of meteoric 10Be spanned more than an order of magnitude across the region (2.9×108 to 73×108 atoms g−1) and are among the highest measured in polar regions. The concentrations of NO3- were similarly variable and ranged from ∼1 µg g−1 to 15 mg g−1. In examining differences and similarities in the concentrations of 10Be and NO3- with depth, we suggest that much of the southern portion of the Shackleton Glacier region has likely developed under a hyper-arid climate regime with minimal disturbance. Finally, we inferred exposure time using 10Be concentrations. This analysis indicates that the soils we analyzed likely range from recent exposure (following the Last Glacial Maximum) to possibly >6 Myr. We suggest that further testing and interrogation of meteoric 10Be and NO3- concentrations and relationships in soils can provide important information regarding landscape development, soil evolution processes, and inferred exposure durations of surfaces in the TAM.

- Abstract
National identity has often been referenced as a culprit in ongoing struggles for rights and freedoms since the inception of modern Turkey. In this chapter, we examine the boundaries of Turkish national identity and the way it has been used in order to consolidate different groups into one. We do so by relying on relevant constructs within social psychology, such as the recognition and nonrecognition of identity and the common ingroup identity model, to shape our argument, while also addressing the historical and sociological background of Turkish identity. We then explore examples from contemporary social psychological research on identity in Kurdish and Alevi groups—groups who are not officially recognized as minorities but who make up the largest minority populations in the country. Our aim is to discuss particular contextual factors of identification, the important antecedents and consequences of that identification, and important points for the study of identity in Turkey.

- Abstract
The Dark Triad (i.e., narcissism, psychopathy, Machiavellianism) has garnered intense attention over the past 15 years. We examined the structure of these traits' measure-the Dark Triad Dirty Dozen (DTDD)-in a sample of 11,488 participants from three W.E.I.R.D. (i.e., North America, Oceania, Western Europe) and five non-W.E.I.R.D. (i.e., Asia, Middle East, non-Western Europe, South America, sub-Saharan Africa) world regions. The results confirmed the measurement invariance of the DTDD across participants' sex in all world regions, with men scoring higher than women on all traits (except for psychopathy in Asia, where the difference was not significant). We found evidence for metric (and partial scalar) measurement invariance within and between W.E.I.R.D. and non-W.E.I.R.D. world regions. The results generally support the structure of the DTDD.

- Abstract
Ecosystems across the United States are changing in complex and surprising ways. Ongoing demand for critical ecosystem services requires an understanding of the populations and communities in these ecosystems in the future. This paper represents a synthesis effort of the U.S. National Science Foundation-funded Long-Term Ecological Research (LTER) network addressing the core research area of "populations and communities." The objective of this effort was to show the importance of long-term data collection and experiments for addressing the hardest questions in scientific ecology that have significant implications for environmental policy and management. Each LTER site developed at least one compelling case study about what their site could look like in 50-100 yr as human and environmental drivers influencing specific ecosystems change. As the case studies were prepared, five themes emerged, and the studies were grouped into papers in this LTER Futures Special Feature addressing state change, connectivity, resilience, time lags, and cascading effects. This paper addresses the "connectivity" theme and has examples from the Phoenix (urban), Niwot Ridge (alpine tundra), McMurdo Dry Valleys (polar desert), Plum Island (coastal), Santa Barbara Coastal (coastal), and Jornada (arid grassland and shrubland) sites. Connectivity has multiple dimensions, ranging from multi-scalar interactions in space to complex interactions over time that govern the transport of materials and the distribution and movement of organisms. The case studies presented here range widely, showing how land-use legacies interact with climate to alter the structure and function of arid ecosystems and flows of resources and organisms in Antarctic polar desert, alpine, urban, and coastal marine ecosystems. Long-term ecological research demonstrates that connectivity can, in some circumstances, sustain valuable ecosystem functions, such as the persistence of foundation species and their associated biodiversi

- Abstract
Important findings from the second decade of the 21st century on the impact of environmental change on biological processes in the Antarctic were synthesised by 26 international experts. Ten key messages emerged that have stakeholder-relevance and/or a high impact for the scientific community. They address (i) altered biogeochemical cycles, (ii) ocean acidification, (iii) climate change hotspots, (iv) unexpected dynamism in seabed-dwelling populations, (v) spatial range shifts, (vi) adaptation and thermal resilience, (vii) sea ice related biological fluctuations, (viii) pollution, (ix) endangered terrestrial endemism and (x) the discovery of unknown habitats. Most Antarctic biotas are exposed to multiple stresses and considered vulnerable to environmental change due to narrow tolerance ranges, rapid change, projected circumpolar impacts, low potential for timely genetic adaptation, and migration barriers. Important ecosystem functions, such as primary production and energy transfer between trophic levels, have already changed, and biodiversity patterns have shifted. A confidence assessment of the degree of 'scientific understanding' revealed an intermediate level for most of the more detailed sub-messages, indicating that process-oriented research has been successful in the past decade. Additional efforts are necessary, however, to achieve the level of robustness in scientific knowledge that is required to inform protection measures of the unique Antarctic terrestrial and marine ecosystems, and their contributions to global biodiversity and ecosystem services.

Journal of Geophysical Research: Biogeosciences, 126(6), (2021): e2020JG006052, https://doi.org/10.1029/2020JG006052., Microbes are widely assumed to be capable of colonizing even the most challenging terrestrial surface environments on Earth given enough time. We would not expect to find surface soils uninhabited by microbes as soils typically harbor diverse microbial communities and viable microbes have been detected in soils exposed to even the most inhospitable conditions. However, if uninhabited soils do exist, we might expect to find them in Antarctica. We analyzed 204 ice-free soils collected from across a remote valley in the Transantarctic Mountains (84–85°S, 174–177°W) and were able to identify a potential limit of microbial habitability. While most of the soils we tested contained diverse microbial communities, with fungi being particularly ubiquitous, microbes could not be detected in many of the driest, higher elevation soils—results that were confirmed using cultivation-dependent, cultivation-independent, and metabolic assays. While we cannot confirm that this subset of soils is completely sterile and devoid of microbial life, our results suggest that microbial life is severely restricted in the coldest, driest, and saltiest Antarctic soils. Constant exposure to these conditions for thousands of years has limited microbial communities so that their presence and activity is below detectable limits using a variety of standard methods. Such soils are unlikely to be unique to the studied region with this work supporting previous hypotheses that microbial habitability is constrained by near-continuous exposure to cold, dry, and salty conditions, establishing the environmental conditions that limit microbial life in terrestrial surface soils., This work was supported by grants from the U.S. National Science Foundation (ANT 1341629 to B.

Biogeosciences, 18(5), (2021): 1629-1644. https://doi.org/10.5194/bg-18-1629-2021., Previous studies have established links between biodiversity and soil geochemistry in the McMurdo Dry Valleys, Antarctica, where environmental gradients are important determinants of soil biodiversity. However, these gradients are not well established in the central Transantarctic Mountains, which are thought to represent some of the least hospitable Antarctic soils. We analyzed 220 samples from 11 ice-free areas along the Shackleton Glacier (∼ 85∘ S), a major outlet glacier of the East Antarctic Ice Sheet. We established three zones of distinct geochemical gradients near the head of the glacier (upper), its central part (middle), and at the mouth (lower). The upper zone had the highest water-soluble salt concentrations with total salt concentrations exceeding 80 000 µg g−1, while the lower zone had the lowest water-soluble N:P ratios, suggesting that, in addition to other parameters (such as proximity to water and/or ice), the lower zone likely represents the most favorable ecological habitats. Given the strong dependence of geochemistry on geographic parameters, we developed multiple linear regression and random forest models to predict soil geochemical trends given latitude, longitude, elevation, distance from the coast, distance from the glacier, and soil moisture (variables which can be inferred from remote measurements). Confidence in our random forest model predictions was moderately high with R2 values for total water-soluble salts, water-soluble N:P, ClO−4, and ClO−3 of 0.81, 0.88, 0.78, and 0.74, respectively. These modeling results can be used to predict geochemical gradients and estimate salt concentrations for other Transantarctic Mountain soils, information that can ultimately be used to better predict distributions of soil biota in this remote region., This research has been supported by the National Science Foundation (grant nos. OPP 1341631, GRFP 60041697, OPP 1341618, OPP 1341629, and OPP 1341736).

Dark Triad ,cross-cultural ,cultural values ,Taverne ,Machiavellianism ,narcissism ,psychopathy - Abstract
The Dark Triad traits (i.e., narcissism, psychopathy, Machiavellianism) capture individual differences in aversive personality to complement work on other taxonomies, such as the Big Five traits. However, the literature on the Dark Triad traits relies mostly on samples from English‐speaking (i.e., Westernized) countries. We broadened the scope of this literature by sampling from a wider array of countries.

Longior surieli n. sp. Fig. 1 A–F, Fig. 2 A–G, Fig. 3 A–E Type material. ♀ holotype, Dominican Republic, La Vega province, Reserva Científica “Ébano Verde”, Sendero El Arroyazo-Casabito; in Antillanax dominicanus; 19°04.42’N, 70°34.18’W; 16/II/2014; G. de los Santos, C. Suriel coll.; CZACC 11.7150. Paratypes 4♀♀, same data as holotype, CZACC 11.7151 –11.7154; 15♂♂, same data as holotype, CZACC 11.7155 –11.7169; ♀, same data as holotype, MNHNSD 05.001; ♂, same data as holotype, MNHNSD 05.002. Description. Female. Body long and slender, widening gradually posterior to head, reaching its maximum width at level of the vulva, then narrowing gradually towards tail. Cuticle thin. Sub-cuticular striae present. Cervical cuticle unarmed, with wide annuli (ca. 8 µm) from the base of the first cephalic annule to ca. the level of the first third of procorpus. Lateral alae well-developed, extending from ca. a body-width posterior to the basal bulb to the level of the anus. Head bearing eight paired, digitiform cephalic papillae, which originate from the external edge of the head, at ca. half of its height. A cuticular, veliform annular lip surrounding the trirradiate oral opening. Amphids lateral, at level of the base of the cephalic papillae. First cephalic annule comparatively long, truncate, slightly dilated. Stoma long and slender, surrounded by an oesophageal collar. Oesophagus consists of a muscular, sub-cylindrical procorpus, its base similar in diameter to the isthmus. Basal bulb rounded, valve-plate well-developed. Intestine simple, sub-rectilinear, its fore region slightly dilated. Rectum comparatively long. Anus as a crescent-like ventromedian slit, anteriorly directed, not prominent. Nerve ring encircling procorpus at ca. 30% of its length. Excretory pore located at ca. half of a body-width posterior to the basal bulb. Vulva a median transverse slit, its lips slightly prominent, located at level of midbody. Vagina muscular, forwardly directed. Genital tract monodelphic-prodelphic, occupying ca. 30% of the body length. Ovary distally reflexed at ca. a body-width posterior to the excretory pore, distal flexure ca. one body-width in length. Oocytes in a single row. Eggs ellipsoidal, bearing eight rough longitudinal ridges in the shell that do not reach the poles. Uterus contains 2– 3 eggs at a time. Tail conical, subulate, ending in a fine tip. Male. Body shorter and comparatively slender than females. Posterior region ventrally curved. Cuticle unarmed, markedly annulated up to the level of the nerve ring, annuli ca. 2 µm. Rest of body with less conspicuous annuli (ca. 1 µm), up to level of the dorsal cuticular thickening. From the base of the head to a distance of ca. 30 µm, the cervical annuli increase their diameter to a maximum of ca. 30 µm, forming a dilatation at the cephalic region. Lateral alae narrow, extending from the last third of the oesophageal region to a distance of ca. 100 µm before the ventromedian pair of copulatory papillae. Head set-off from body by a deep groove, bearing eight ellipsoidal, slightly flattened cephalic papillae arranged as two sub-dorsal and two sub-ventral pairs. Six digitiform lips originate from the internal edge of the cephalic papillae and project to the center of the oral aperture. Lips are arranged as one lip dorsal, one ventral, two sub-dorsal and two sub-ventral; the latter flanking the dorsal and ventral lips, respectively. Amphids lateral, as crescent-like pores. Oesophagus consists of a muscular, sub-cylindrical procorpus, diminishing its diameter toward its posterior half, almost equal to the diameter of the isthmus at the level of their junction. Basal bulb rounded, valve-plate well-developed. Intestine simple, its fore region slightly inflated. Nerve ring encircling procorpus at ca. 45% of its length. Excretory pore located at ca. 1.5 body-widths posterior to the basal bulb. Monorchic, testis outstretched, its distal end located at a distance of a little less than a body-width behind the excretory pore. Vas deferens with three distinguishable regions: an anterior region with granular content; a median, slightly swollen region, also granular (granuli slightly shorter in diameter) and a posterior region that diminishes its diameter through the cloaca. Spicule absent. A ventral bursa-like structure present. The tail tip presents a hammer-like appearance due to a ventral bending and a dorsal knob-like protuberance. Dorsal cuticle of the tail end is thickened and smooth. Such thickening forms a cuticular crest at the tail tip that extends terminally and laterally at the ventral bending. Phasmids pore-like, lateral, located at level of the beginning of the bursa. Four pairs of copulatory papillae, two pre-cloacal and two post-cloacal. A ventromedian large pair consist of duplex papillae very close each other on an ellipsoidal protuberance (appear to be a single papilla in lateral view) at ca. 120–170 µm from the tail tip. A sub-lateral pair of papillae is at ca. the level of the beginning of the dorsal cuticular thickening. The remaining two post-cloacal pairs consist of small papillae: one pair ventral, located at the tip of a papilliform protuberance just posterior to the bursa and one pair ventral, sub-terminal, close to the tail tip, below and in contact with the terminal cuticular crest. Differential diagnosis. Longior surieli n. sp. presents lateral alae extending from ca. a body width posterior to the basal bulb to the level of the anus, similar to the rest of the species of the genus. This feature differentiates it from L. semialata, which possess lateral alae that extend from the level of the vulva to just before the anus (Hunt 1981). In addition, the oesophagus is comparatively shorter in L. surieli n. sp. (b = 4.11–4.52 vs. 3.30–3.70) and the tail is longer than L. semialata (c = 5.31–5.83 vs. 5.80–8.60). Longior surieli n. sp. has a body shorter than L. longicollis, L. longior and L. zumpimito n. sp. (2.550 –2.850 mm vs. 2.980 –3.640 mm vs. 3.500 –4.525 mm vs. 3.110 –3.920 mm). The tail of L. surieli n. sp. is comparatively longer than in the aforementioned species (c = 5.31–5.83 vs. 9.03–9.33 vs. 6.24–8.54 vs. 7.93–9.58). Also, the body of L. surieli n. sp. is comparatively more robust than L. longior and L. zumpimito n. sp. (a = 14.47–15.83 vs. 23.61–28.28 vs. 18.10–22.64). Longior surieli n. sp. is longer than L. elieri and L. panamensis (2.550 –2.850 mm vs. 1.650 –1.950 mm vs. 1.670 –2.060 mm). The body of L. surieli n. sp. is comparatively more robust than L. elieri (a = 14.47–15.83 vs. 17.11–18.44) and its oesophagus is comparatively longer (b = 4.11–4.52 vs. 3.65–3.98). Longior similis differs from L. surieli n. sp. by its tail being comparatively shorter (c = 6.22–6.99 vs. 5.31–5.83) and a genital tract that comprises ca. 40% of the body length, instead of ca. 30% in L. similis. The excretory pore of L. surieli n. sp. is located at ca. a half of a body-width behind the basal bulb, more posterior than in L. lamothei n. sp., with the excretory pore just posterior to the basal bulb. Males of L. surieli n. sp. can be easily differentiated from the aforementioned species by having a swelling next to the head, formed by a group of cuticular annuli, their diameter increased. It can be differentiated from L. longi-collis by its more robust body (a = 11.19–15.50 vs. 21.65–23.79) and a comparatively shorter tail (c = 38.33–58.00 vs. 30.66–32.83). The oesophagus (b = 2.94–3.75 vs. 3.79–3.97) and the tail (c = 38.33–58.00 vs. 62.50–72.00) of L. surieli n. sp. are comparatively longer than L. zumpimito n. sp. Longior surieli n. sp. is slightly longer than L. lamothei n. sp. and L. similis (1.000 –1.550 vs. 0.850 –1.030 vs. 0.860 –1.370 mm). Also, L. lamothei n. sp., L. similis and L. longior lack the hammer-like structure at the tail tip, which is present in L. surieli n. sp. Type locality.

Last pair of post-cloacal papillae small, ventral, sub-terminal, close to the tail tip, located below the terminal cuticular crest. Differential diagnosis. The females of L. zumpimito n. sp. can be differentiated from most of the nominal species of the genus by its body length (3.110 –3.920 mm), only similar to L. longior (3.500 –4.525 mm) and L. longicollis (2.980 –3.640 mm). In the rest of the species the female body length is under 3.000 mm, with the exception of L. similis (2.675 –3.075 mm). It differs from L. longior by having the body comparatively more robust (a = 18.10–22.64 vs. 23.61–28.28) and the genital tract occupying ca. 34% of the body length in opposition to ca. 20% in L. longior. Longior zumpimito n. sp. differs from L. longicollis by its more anterior vulva (V% = 49.86–54.89 vs. 57.72–61.81). Longior zumpimito n. sp. can be differentiated from L. semialata by the extension of the lateral alae from a distance of 1–1.5 body-widths posterior to the basal bulb to the level of the anus in opposition to the lateral alae extending from the level of the vulva to the anus. The females of L. zumpimito n. sp. present the tail comparatively shorter than L. elieri, L. lamothei n. sp., L. similis, L. surieli n. sp. and L. panamensis (c = 7.93–9.58 vs. 5.00–5.34 vs. 5.57–6.35 vs. 6.22–6.99 vs. 5.31–5.83 vs. 5.42–6.30). Additionally, L. zumpimito n. sp. presents the oesophagus comparatively shorter than L. elieri and L. panamensis (b = 4.32–4.84 vs. 3.65–3.98 vs. 3.59–4.20). Both, L. lamothei n. sp. and L. surieli n. sp. are more robust than L. zumpimito n. sp. (a = 14.20–16.33 vs. 14.47–15.83 vs. 18.10–22.64). The males of L. zumpimito n. sp. can be differentiated from L. longicollis by its shorter body (1.250 –1.380 mm vs. 1.380 –1.970 mm) and comparatively shorter tail (c = 62.50–72.00 vs. 30.66–32.83). L. zumpimito n. sp. differs from L. lamothei n. sp., L. longior and L. surieli n. sp. by its oesophagus (b = 3.79–3.97 vs. 3.70–3.75 vs. 3.13–3.63 vs. 2.94–3.75) and tail (c = 62.50–72.00 vs. 38.00–46.00 vs. 43.33–51.27 vs. 38.33–58.00) comparatively shorter.
