Abstract: Urban green spaces vary in their local and regional attributes, and this variation can have contrasting effects on the ability of urban green spaces to support biodiversity. Here we assess the response of four insect taxa to urban development in Sydney, Australia, using a multiscale approach. We sampled four insect orders (Coleoptera, Diptera, Hemiptera and Hymenoptera) at 19 sites and employed a) multivariate analyses to test the responses of insect communities to environmental management regimes, and b) generalised linear models to determine taxa responses to urban green spaces at local and regional scales. We hypothesised that environmental management regimes (forest, urban forest remnant, and recreational park) affected the species composition of insect com- munities but found no evidence to support this hypothesis. Only species composition of hemipteran communities responded at this scale, with assemblages in urban forest remnants distinct to those in forests and recreational parks. Conversely, site attributes at local and regional scales had distinct effects on each insect group. While species richness of all taxa was positively related to local flower species richness, they exhibited variable re- sponses to regional attributes such as greenspace proportion and site area. The taxon-specific response to local and regional attributes of urban green spaces suggest that there is no silver-bullet for managing local or regional traits to promote diversity of major insect groups in urban areas. These results highlight the opportunities for managers and planners to develop unique and targeted taxon-specific interventions aiming to enhance urban insect diversity. Resumen: Los espacios verdes urbanos varían en sus atributos locales y regionales, y esta variación puede generar efectos contrastantes en su habilidad de soportar la biodiversidad. En este artículo evaluamos la respuesta de cuatro grupos de insectos al desarrollo urbano en Sídney, Australia, usando una aproximación multi-escala. Muestreamos cuatro ordenes de insectos (Coleoptera, Diptera, Hemiptera y Hymenoptera) en 19 sitios, y utilizamos a) análisis multivariados para evaluar las respuestas de las comunidades de insectos a los régimenes de manejo ambiental, y b) modelos lineales generalisados para determinar las respuestas de estos grupos de insectos en las escalas locales y regionales de los espacios verdes urbanos. Hipotetizamos que diferentes regímenes de manejo ambiental (bosque, remanentes de bosque urbano, y parques recreativos) tendrían efecto en la composición de especies de las comunidades de insectos, pero no encontramos evidencia que soporte esta hipótesis. Únicamente la composición de especies de las comunidades de hemípteros respondió a esta escala, con los ensamblajes de especies en los remanentes urbanos de bosque siendo significativamente diferentes a los ensamblajes de especies en las bosques y parques recreativos. De manera contraria, los atributos locales y regionales de los espacios verdes urbanos tuvieron efectos distintos en cada uno de los grupos de insectos estudiados. Mientras que la riqueza de especies de todos los grupos estuvo positivamente relacionada a la riqueza local de flores, todos los grupos exhibieron respuestas variadas a atributos regionales tales como la proporción de área verde y el área del espacio verde urbano. Estas respuestas específicas de cada grupo de insectos a los atributos regionales de los espacios verdes urbanos sugiere que no hay soluciones universales (en los regímenes de manejo ambiental) para promover la diversidad de insectos. Estos resultados demuestran las oportunidades que administradores y planeadores urbanos tienen para desarrollar intervenciones únicas y dirigidas a grupos particulares de insectos, para proteger la diversidad de los insectos en centros urbanos.

Abstract: Biological and physiological changes in response to stress are crucial to achieving adaption to environmental constraints. Typical stress responses activate the sympathetic nervous system and the hypothalamic-pituitary-adrenal cortical axis, which aim to maintain homeostasis in response to demands and influence various biological responses at neuroendocrine, cellular, and immune levels. In particular, there is compelling evidence showing the devastating effects of high-stress levels on immune responses and brain functionality. In that sense, data suggest that a sustained stress-physiological response predicts decreases in immunity and leads to allostatic load, the wear, and tear of biological systems. Similarly, in cancer research, chronic stress levels have been reported to impair the bodysurveillance systems and be related to cancer incidence, progression, and mortality. Despite the evidence demonstrating the associations between stress and cancer, there are limited data on whether lifetime stress exposure relates to clinical indicators of cancer aggressiveness. Considering the evidence showing the adverse effects of prolonged stress exposure on cancer disease, this thesis aimed to explore the relationship between lifetime stress exposure and the clinical characteristics of tumor-aggressiveness in a cohort of patients affected with triple-negative breast cancer (TNBC). Likewise, as research has shown that coping responses moderate the stress-physiological response, we aimed to investigate the role of coping responses in moderating the association between tumor aggressiveness and lifetime stress exposure. According to the scientific literature, high-stress levels would increase physiological arousal and allostatic load favoring a debilitated immune system. Thus, we hypothesized finding positive associations between lifetime stress exposure and tumor-aggressiveness. In the same line, we suspected that adaptative coping styles would be negatively related to tumoraggressiveness. The participants of this study were 29 women diagnosed with TNBC who were treated in the University Hospital for Gynecology Pius-Hospital (Oldenburg, Germany). Correlation and moderation regression analyses with the use of composite scores were conducted. Overall, we could not demonstrate significant associations between lifetime stress exposure and coping responses on the clinical indicators of tumor aggressiveness in this cohort of patients. Possible explanations for these results are discussed, and suggestions for future research are provided. This study was the first to investigate the effect of lifetime stress exposure and coping response on the aggressive tumor characteristics of TNBC. We provided a deep theoretical framework to understand the interplay between biological and psychological aspects of cancer disease, and we hope that our recommendations may serve as a base for upcoming studies.

Abstract: Despite some epidemiological evidence on the protective effects of polyphenol intake on epithelial ovarian cancer (EOC) risk from case-control studies, the evidence is scarce from prospective studies and non-existent for several polyphenol classes. Therefore, we aimed to investigate the associations between the intake of total, classes and subclasses of polyphenols and EOC risk in a large prospective study. The study was conducted in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort, which included 309,129 adult women recruited mostly from the general population. Polyphenol intake was assessed through validated country-specific dietary questionnaires and the Phenol-Explorer database. During a mean follow-up of 14 years, 1469 first incident EOC cases (including 806 serous, 129 endometrioid, 102 mucinous, and 67 clear cell tumours) were identified. In multivariable-adjusted Cox regression models, the hazard ratio in the highest quartile of total polyphenol intake compared with the lowest quartile (HRQ4vsQ1) was 1.14 (95% CI 0.94–1.39; p-trend = 0.11). Similarly, the intake of most classes and subclasses of polyphenols were not related to either overall EOC risk or any EOC subtype. A borderline statistically significant positive association was observed between phenolic acid intake (HRQ4vsQ1 = 1.20, 95% CI 1.01–1.43; p-trend = 0.02) and EOC risk, especially for the serous subtype and in women with obesity, although these associations did not exceed the Bonferroni correction threshold. The current results do not support any association between polyphenol intake and EOC in our large European prospective study. Results regarding phenolic acid intake need further investigation.

Abstract: Islands have been considered natural laboratories to study evolutionary processes. Ibiza is a small island in Spain whose population stands out from other Spanish populations due to its particular demographic and historical processes. War, famine, and several epidemics have affected Ibizans, and these phenomena could have left signatures of positive selection in their genomes. Here, we used three different methodologies to detect positive selection: The Population Branch Statistic (PBS), the Integrated Haplotype Score (iHS), and the Cross-Population Extended Haplotype Homozygosity (XP-EHH). We used a sliding windows approach to control for spurious results. The candidate windows for selection were chosen using three different criteria for each test: maximum and mean score within each window, and proportion of high scores in each window. Only the windows being simultaneously on the top of each of the three criteria were selected for annotation and enrichment analyses. The most common traits associated with the SNPs present in the candidate windows were blood function, cardiovascular diseases, body mass measures, lipid metabolism, renal function, and skin diseases. We suggest some hypotheses to explain the selection signatures related to some of these traits and some recommendations for further studies to overcome the present research's limitations. Resumen: Las islas se han considerado laboratorios naturales para estudiar procesos evolutivos. Ibiza es una pequeña isla de España cuya población se distingue del resto de poblaciones españolas por sus particulares procesos demográficos e históricos. La guerra, el hambre y varias epidemias han afectado a los ibicencos, y estos fenómenos podrían haber dejado huellas de selección positiva en sus genomas. Aquí, utilizamos tres metodologías diferentes para detectar selección positiva: el Population Branch Statistic (PBS), el Integrated Haplotype Score (iHS) y la Cross-Population Extended Haplotype Homozygosity (XP-EHH). Usamos un enfoque de ventanas deslizantes para controlar resultados espurios. Las ventanas candidatas para la selección se eligieron utilizando tres criterios diferentes para cada prueba: puntuación máxima y media dentro de cada ventana, y proporción de puntuaciones altas en cada ventana. Solo las ventanas que se encontraban simultáneamente en la parte superior de cada uno de los tres criterios se seleccionaron para los análisis de anotación y enriquecimiento. Los rasgos más comunes asociados con los SNP presentes en las ventanas candidatas fueron la función sanguínea, las enfermedades cardiovasculares, las medidas de masa corporal, el metabolismo de los lípidos, la función renal y las enfermedades de la piel. Sugerimos algunas hipótesis para explicar las señales de selección relacionadas con algunos de estos rasgos y algunas recomendaciones para futuros estudios para superar las limitaciones de la presente investigación.

Abstract: Thanks to theoretical and technological advances in evolutionary biology we can look into genomic patters to infer evolutionary processes such as divergence and gene flow, and how they shape the genomic landscape. However, such studies tend to focus on model species with small genomes and overlook non-model species with large repetitive genomes, thus missing generality across a big part of the tree of life. Here, we develop new genomic methods for the grasshopper Chorthippus parallelus, which is characterized by a giant genome of 13.5 Gb, which is not only expensive to sequence but impossible to assemble using state of the art methodologies. Alternative genomic methods involving Exome Capture have been developed in the last years to study other species with large repetitive genomes but these approaches have not been developed in grasshoppers yet. In this study we test two different library protocols — Nextera and Collibri — coupled with multiplexing, exome capture and Illumina sequencing. To test which library protocol was the best to be coupled with the exome capture we compared the number of retained reads and PCR duplicates in both protocols after sequencing. We found that Nextera was the library protocol with the highest number of retained reads and lowest number of PCR duplicates making it the best library protocol to be used in future studies. To test If the capture worked, these reads were mapped to a file containing target sequences and the coverage was then compared to the coverage resulting from a no-enrichment protocol. The capture protocol had a up to ~26 fold enrichment confirming that the baits hybridized with the target sequences. We also found that beads attached to the baits inhibit the polymerase, suggesting that beads should be removed before the amplification step. Two technical replicates showed consistent patterns but higher input of DNA seems to increase the efficiency of the capture. Together, our results suggest that this protocol could be used in organisms with large genomes, like grasshoppers, for which no reference genome is available, helping to fill the gaps in the knowledge of the genomic landscape of differentiation in these underrepresented species.

Resumen: Robert Nozick es conocido por sus posiciones libertarias, expuestas en su libro Anarquía, Estado y Utopía. Sin embargo, textos posteriores del autor (en particular La vida examinada) parecen mostrar una renuncia al libertarianismo y una crítica a éste como posición política y ética. A través del análisis de su último libro (Invariances) este trabajo busca identificar si existe o no esa renuncia y, además, analiza el alcance, condiciones y contenido de la renuncia o, al menos, de los cambios en perspectiva. En ese sentido, el trabajo analiza si Invariances presenta un marco libertario y si este marco es compatible con el presentado en Anarquía, Estado y Utopía, tanto desde la perspectiva de la teoría del Estado, como desde la perspectiva de la ética. Abstract: Robert Nozick is known for his libertarian positions, presented in his book Anarchy, State and Utopia. Nevertheless, later books by the author (particularly The examined life) seem to show a renunciation of libertarianism and a criticism of it as a political and as an ethical position. By analyzing his last book (Invariances) this work attempts to identify whether this renunciation exists or not and, also, analyzes the extent, conditions and content of this renunciation or, at least, if its changes in perspective. In this sense, this work analyzes if Invariances presents a libertarian framework and if this framework is compatible with the one exposed in Anarchy, State and Utopia, both from the perspective of the theory of the State as from the perspective of ethics.

Abstract: Most socioeconomic studies on illicit economies have been approached through the lens of war economics, hence, a wide variety of them are rooted in the greed and grievance literature. On contrast, recent studies (Eventon & Gutierrez, 2020, p. 10) (Gutierrez, 2020) (International Journal of Drug Policy, 2021) have found that illicit economies, particularly on illicit crops, arise as a source of livelihoods for impoverished farmers that provides opportunities to enhance agricultural practices and local development such as infrastructure, land access, access to credit, and supplies for cropping coca, also for other licit products and services. In addition, its origin is not only the result of poverty or "lack of development", but of a modernisation process in which coca has emerged as an "autonomous form of development." (Gootenberg, 2021). The aim of this study which dialogues with these new analytical frames, is measuring the influence that subnational inequality measures have in explaining the variation of coca area –among municipalities identified as coca leaf producers— and contrasting them with municipal poverty measures. I will argue that coca crops expansion adapts to different land regimes, but particularly in uneven distribution of land, where coca interacts with other conditions of economic precarity (Rigg, et al., 2016). Based on a longitudinal analysis of 217 Colombian municipalities, I contrast the effect of Gini of land owning and the Dependency on National Transfers on coca area from 2014 and 2018. The results feeds into and contributes to an Agrarian Change perspective to explain the influence of structures and mechanisms that shape rural change (Cramer & Richards, 2011); and a subnational analysis to make visible “within-country heterogeneity” of the association coca and land inequality. Resumen: La mayoría de los estudios socioeconómicos sobre las economías ilícitas se han abordado a través de los lentes de la economía de la guerra, por lo que una gran variedad de ellos están arraigados en la literatura de la codicia y el agravio. Por el contrario, estudios recientes (Eventon & Gutierrez, 2020, p. 10) (Gutierrez, 2020) (International Journal of Drug Policy, 2021) han encontrado que las economías ilícitas, en particular sobre los cultivos ilícitos, surgen como una fuente de sustento para los agricultores empobrecidos que proporciona oportunidades para mejorar sus prácticas agrícolas y el desarrollo local, tales como la infraestructura, el acceso a la tierra, el acceso al crédito y los suministros para el cultivo de coca, también para otros productos y servicios lícitos. Además, su origen no es sólo el resultado de la pobreza o la "falta de desarrollo", sino de un proceso de modernización en el que la coca ha surgido como una "forma autónoma de desarrollo". (Gootenberg, 2021). El objetivo de este estudio, que dialoga con estos nuevos marcos analíticos, es medir la influencia que tienen las medidas de desigualdad subnacional en la explicación de la variación de la superficie de coca -entre los municipios identificados como productores de hoja de coca- y contrastarlas con las medidas de pobreza municipal. Argumentaré que la expansión de los cultivos de coca se adapta a diferentes regímenes de tierra, pero particularmente en la distribución desigual de la tierra, donde la coca interactúa con otras condiciones de precariedad económica (Rigg, et al., 2016 ). A partir de un análisis longitudinal de 217 municipios colombianos, contrasto el efecto del Gini de la propiedad de la tierra y la Dependencia de las Transferencias Nacionales sobre la superficie de coca de 2014 y 2018. Los resultados alimentan y contribuyen a una perspectiva de Cambio Agrario para explicar la influencia de las estructuras y mecanismos que moldean el cambio rural (Cramer & Richards, 2011); y un análisis subnacional para hacer visible la "heterogeneidad dentro del país" de la asociación coca y desigualdad de la tierra.

Abstract: This research aims at critically appraising the connections that can be traced between the regulation of strategic approaches towards public procurement and the interest of integrating sustainability and innovation driven goals within procurement proceedings. As such, the investigation is framed under areas of research that have not acquired significant attention until recently; on the one hand, the interaction of sustainability and environmental concerns has increased at the same rate that the environmental crisis has worryingly amplified, and the study of law and technology has simultaneously gained attention as regulation attempts to keep the pace in which technology rapidly change human experience. Along these two intertwined objects of academic interest, this research will attempt to demonstrate that the synergy between public procurement and sustainability concerns may be further enhanced and strengthened by reaching out to the support that technological innovations may provide along the multiple stages of the procurement process. The investigation is thus concerned not only in identifying the advantages derived from such cooperative interaction, but also in examining the margins and shortcomings which this involvement entails.

Abstract: This essay aims to review some of the postulates of the scientist, theologian and Jesuit priest Teilhard de Chardin, in the light of integral ecology, environmentalism and the contemporary critique of modernity. The general objective is to highlight the preponderance of the Teilhardian project of the human and to inquire about its resolving potential in the face of environmental conflicts. A controversy about the natural or human origin of disasters is analyzed as a starting point. After recognizing that disasters cannot be treated as natural phenomena, it is observed that they could not be considered human either, without revealing an inconclusive notion of the meaning of the human. Disaster resolution and our unrealized humanity are presented as parallel itineraries. The arguments throughout the text aim, on the one hand, to blur the limits drawn by modernity and secularism to claim exclusive access to the rational and managerial knowledge of human communities; on the other hand, the convenience of broadening the epistemological horizon and the benefits of enriching the intellectual and practical possibilities to contribute to the qualification of the human are postulated. In this case, Teilhard de Chardin’s perspective is presented as a reference. Resumen: Este ensayo pretende revisar algunos de los postulados del científico, teólogo y sacerdote jesuita Teilhard de Chardin, a la luz de la ecología integral, el ambientalismo y la crítica contemporánea a la modernidad. El objetivo general es resaltar la preponderancia del proyecto teilhardiano de lo humano e indagar sobre su potencial resolutivo frente a los conflictos ambientales. Se analiza como punto de partida una controversia sobre el origen natural o humano de los desastres. Después de reconocer que los desastres no pueden tratarse como fenómenos naturales se observa que no podrían, tampoco, considerarse humanos, sin desvelar una noción inconclusa de lo que significa el sentido de lo humano. La resolución de desastres y nuestra humanidad no realizada se presentan como itinerarios paralelos. Los argumentos a lo largo del texto pretenden, por un lado, desdibujar los límites trazados por la modernidad y el secularismo para atribuirse el acceso exclusivo al conocimiento racional y gerencial de las comunidades humanas; por otro, se postula la conveniencia de ampliar el horizonte epistemológico y los beneficios de enriquecer las posibilidades intelectuales y prácticas para contribuir en la cualificación de lo humano. En esta causa se presenta como referencia la perspectiva de Teilhard de Chardin.
