Large‐scale marine protected areas and imaginaries of progress in ocean governance

Large‐scale marine protected areas (LSMPAs) are an increasingly important feature of global conservation as countries strive to meet international commitments to protect 30% of all land and sea areas by 2030. In this paper, we contribute to current interest in the imaginaries that underpin environmental governance. Drawing together work on spatial and sociotechnical imaginaries, we examine how ocean imaginaries get bound up with the rise of large, protected areas in the ocean. We develop a typology of three ocean imaginaries associated with LSMPAs, which is elaborated through an empirical analysis of the political discourse that surrounded the designation of 17 LSMPAs since 2010. We examine extracts of government statements, speeches and press releases predominantly in news article sources and government websites to consider how these ocean imaginaries are institutionally stabilised and aligned with advances in science and technology. Our analysis reinforces an understanding that the kinds of spatial imaginaries that are created for environmental governance shape and are shaped by policy and management strategies. We also find that both visions of ocean spaces and the social worlds that perceive them can be multiple. We contend that research and policy need to recognise LSMPAs and other area‐based conservation measures as more‐than‐technical pursuits, and harness geographic scholarship to consider and enable a multiplicity of imaginaries in exploring options for environmental governance

Recuperación de la diversidad morfológica de los escleractinios durante el Jurásico temprano en la provincia de Mendoza, Argentina

After a diversity peak during the Late Triassic, corals were severely affected by the end-Triassic extinction. The study of their recovery is fundamental for a better understanding of the ecological rearrangement undergone by Early Jurassic marine invertebrate faunas. In this contribution we analyze the morphologic recovery shown by scleractinians in southern Mendoza Province, which is the only place in the Neuquén Basin with marine outcrops spanning the Triassic/Jurassic boundary. A two-stage recovery pattern was recognized. During the first stage (Hettangian–Sinemurian) only solitary corals, most of them discoidal, could be found. After a hiatus encompassing the latest Early Sinemurian and the Late Sinemurian, the second stage (Pliensbachian) developed. A sharp increase in morphological diversity of solitary corals is then recorded, with discoidal, cupolate, patellate, turbinate, trochoid/turbinate, trochoid/ceratoid and maybe cylindrical morphologies. Additionally, colonial forms with low degree of corallite integration (phaceloid and cerioid colonies) appeared in the basin. The diversification trend hereby described provides useful insight regarding the scleractinian recovery after the end-Triassic mass extinction event within southern basins of South America. Furthermore, this recovery pattern is comparable with the one recognized for other regions (Chile, western North America, central Asia) yet it differs from that observed in some European basins. The trend outlined herein for Early Jurassic corals from the Neuquén Basin may reflect a large-scale phenomenon and/or the action of local adverse conditions (such as fluvial influence), which is open to further testing.Después de un máximo de diversidad durante el Triásico Tardío, los corales se vieron severamente afectados por la extinción del final del Triásico. El estudio de su recuperación resulta fundamental para una adecuada comprensión del reacomodamiento ecológico de las faunas de invertebrados marinos del Jurásico Temprano. Se analiza aquí la recuperación morfológica experimentada por los escleractinios en el sur de la Provincia de Mendoza, único lugar en la Cuenca Neuquina con afloramientos marinos del pasaje Triásico–Jurásico. Se reconoce un patrón de recuperación de dos fases. Durante la primera fase (Hetangiano–Sinemuriano) sólo se registran corales solitarios, en su mayoría discoidales. Después de un hiato que abarcó la última parte del Sinemuriano Temprano y todo el Sinemuriano Tardío se desarrolló la segunda fase (Pliensbachiano). Se registra entonces un incremento marcado en la diversidad morfológica de los corales solitarios, con formas discoidales, cupulares, pateladas, turbinadas, trocoides/turbinadas, trocoides/ceratoides y posiblemente cilíndricas. Además, aparecen en la cuenca formas coloniales con bajo grado de integración de sus coralitos (faceloides y cerioides). La diversificación reconocida aporta información útil acerca de la recuperación de los escleractinios tras la extinción masiva de finales del Triásico en cuencas australes de Sudamérica. Este patrón de recuperación es comparable al de otras regiones (Chile, oeste de Norteamérica, Asia central) aunque difiere del hallado en algunas cuencas europeas. La tendencia aquí esbozada para los corales del Jurásico Temprano de la Cuenca Neuquina podría estar reflejando un fenómeno de gran escala y/o condiciones locales adversas (como influencia fluvial), lo cual plantea la posibilidad de futuros estudios.Facultad de Ciencias Naturales y Muse

Global urban environmental change drives adaptation in white clover

Urbanization transforms environments in ways that alter biological evolution. We examined whether urban environmental change drives parallel evolution by sampling 110,019 white clover plants from 6169 populations in 160 cities globally. Plants were assayed for a Mendelian antiherbivore defense that also affects tolerance to abiotic stressors. Urban-rural gradients were associated with the evolution of clines in defense in 47% of cities throughout the world. Variation in the strength of clines was explained by environmental changes in drought stress and vegetation cover that varied among cities. Sequencing 2074 genomes from 26 cities revealed that the evolution of urban-rural clines was best explained by adaptive evolution, but the degree of parallel adaptation varied among cities. Our results demonstrate that urbanization leads to adaptation at a global scale

Omecamtiv mecarbil in chronic heart failure with reduced ejection fraction, GALACTIC‐HF: baseline characteristics and comparison with contemporary clinical trials

Aims: The safety and efficacy of the novel selective cardiac myosin activator, omecamtiv mecarbil, in patients with heart failure with reduced ejection fraction (HFrEF) is tested in the Global Approach to Lowering Adverse Cardiac outcomes Through Improving Contractility in Heart Failure (GALACTIC‐HF) trial. Here we describe the baseline characteristics of participants in GALACTIC‐HF and how these compare with other contemporary trials. Methods and Results: Adults with established HFrEF, New York Heart Association functional class (NYHA) ≥ II, EF ≤35%, elevated natriuretic peptides and either current hospitalization for HF or history of hospitalization/ emergency department visit for HF within a year were randomized to either placebo or omecamtiv mecarbil (pharmacokinetic‐guided dosing: 25, 37.5 or 50 mg bid). 8256 patients [male (79%), non‐white (22%), mean age 65 years] were enrolled with a mean EF 27%, ischemic etiology in 54%, NYHA II 53% and III/IV 47%, and median NT‐proBNP 1971 pg/mL. HF therapies at baseline were among the most effectively employed in contemporary HF trials. GALACTIC‐HF randomized patients representative of recent HF registries and trials with substantial numbers of patients also having characteristics understudied in previous trials including more from North America (n = 1386), enrolled as inpatients (n = 2084), systolic blood pressure < 100 mmHg (n = 1127), estimated glomerular filtration rate < 30 mL/min/1.73 m2 (n = 528), and treated with sacubitril‐valsartan at baseline (n = 1594). Conclusions: GALACTIC‐HF enrolled a well‐treated, high‐risk population from both inpatient and outpatient settings, which will provide a definitive evaluation of the efficacy and safety of this novel therapy, as well as informing its potential future implementation

Imaginaries : Oceanic Bordering with Large-Scale Marine Protected Areas

Large-scale marine protected areas (LSMPAs) are growing in prominence as an area-based conservation strategy that places vast areas of the ocean (more than 150,000 square kilometres at a time) into formal protection. While LSMPAs are lauded for their conservation potential—for example, their ability to protect entire marine habitats and the ranges of highly mobile marine species—they also fulfil other political, social and economic functions. This chapter considers the role of imagination in the oceanic bordering practices of LSMPA designation. It demonstrates how LSMPAs are mobilised as resources by powerful actors to promote visions of progress tied to national identities centred on continuing connection to the ocean. In doing so, it illustrates how there is more at stake in the establishment of LSMPAs than conservation and marine management alone. The oceanic bordering agendas associated with LSMPAs not only redraw ocean maps, but also reinforce and renew national identities in relation to ocean space.</p

Ceramica a vernice nera di età ellenistica da siti della Sicilia nord-occidentale : considerazioni tipologiche ed analisi archeometriche

In questo studio sono state integrate osservazioni tipologiche, condotte su forme a vernice nera rinvenute a Palermo, Termini Imerese, Monte Iato e Marineo, con i dati ricavati dalla caratterizzazione mineralogica, petrografica e chimica degli impasti. I 55 campioni selezionati appartengono a due forme : un piatto («Lamboglia 36 » , serie 1310-1320 di J.-P. Morel), tra i più comuni nella Campana A di I e II secolo a. C. ; ed una coppa di produzione locale o regionale, attestata (fine IV-III secolo a. C.) in insediamenti della Sicilia nord-occidentale, che è stata utilizzata anche come «gruppo di riferimento » chimicopetrografico. Sono stati distinti due gruppi composizionali, da ascrivere uno all’area del Golfo di Napoli, l’altro ad ambito produttivo locale, che per le caratteristiche mineralogico-petrografiche e chimiche è riferibile alle Argille di Ficarazzi (periferia orientale di Palermo). Ad entrambi i gruppi appartengono reperti del piatto Lamboglia 36, ma solo al secondo i campioni della coppa.Belvedere Oscar, Burgio Aurelio, Iliopoulos Ioannis, Montana Giuseppe, Spatafora Francesca.
