The archaeological investigations conducted between 2009 and 2013 at Japnišče, a site in Miren, unearthed part of a cemetery from the late 5th and early 6th century. It is a small cemetery located ...at a formerly major road that connected Aquileia and Emona. Nine burials have thus far been investigated, though the scattered finds of human bones in the mixed layers and fills of pits suggest the burial ground was originally larger. A particular feature of the cemetery is the East Germanic elements visible in the costume and the artificially deformed skulls. We argue that these elements indicate the presence of a Germanic population, with historical sources pointing to the Ostrogoths as the most likely people. The interpretation of the Miren cemetery relies on a meticulous typo-chronological analysis of the recovered grave goods, as well as a study of objects from the late 4th and early 5th centuries that originated from the Lower Danube Basin, and the study of East Germanic elements from the late 5th and the initial decades of the 6th century unearthed at sites in Slovenia. Finally, the site is compared with similar cemeteries in Italy and Austria.
La proliferación en los últimos años de los estudios autoriales, de la mano de especialistas como Jêrome Meizoz, Ruth Amossy o Dominique Mainguenau, ha permitido explorar el lugar del autor en el ...campo literario y sus diferentes estrategias de posicionamiento. Sin embargo, las investigaciones en la intersección entre los estudios autoriales y los estudios de género, inauguradas y desarrolladas en el ámbito hispánico por expertas como Meri Torras, Aina Pérez Fontdevila o Eleonora Cróquer Pedrón, no han alcanzado aún la notoriedad que merecen para atender a las características particulares que manifiesta la autoría de mujeres. En la medida en que las escritoras han sido históricamente desautorizadas para ocupar una posición autorial reconocida, han necesitado recurrir a múltiples estrategias de autolegitimación. Este artículo se propone indagar en estas relaciones entre género y autoría con el objetivo de exponer un mecanismo de legitimación observado en la literatura hispánica reciente. En esta dirección, se formula la inscripción autorial como una nueva categoría de análisis para la función de autora y se ofrece un estudio de caso centrado en el diagnóstico de esta propuesta teórica en Un ojo de cristal (2014), de la escritora vasca Miren Agur Meabe. Además, se exploran los nexos entre el cuerpo y la autoría femenina a partir de nociones como “corpografía autorial”, “autorialidad corporal” y “sensocorpografía” para concluir que la inscripción de la autoría y la textualización del cuerpo extraordinario caminan conjuntamente en la dirección de la autolegitimación de una autoría disidente.
The Andes mountain range in South America has a high level of endemism and is a major source of ecosystem services. The Andes is increasingly threatened by anthropogenic disturbances that have ...allowed the establishment of non-native plants, mainly in the lower elevation areas. However, synergies between climate change and anthropogenic pressure are promoting the spread of non-native plants to higher elevation areas. In this article, we evaluate and identify the main non-native plants invading Andean ecosystems, and assess their taxonomic families, growth forms and distribution patterns. Based on a systematic literature review, we identified the importance of climatic and anthropogenic factors as drivers of non-native species establishment in Andean ecosystems and the main impacts of non-native plants in the Andes. We then identified research gaps across each biogeographic region in the Andes. Finally, we highlight key elements to better tackle the problem of non-native plant invasions in Andean ecosystems, including the need for a systematic monitoring of invasion patterns and spread (e.g. MIREN protocol) and a common policy agenda across international borders for the prevention and management of non-native plants in this highly vulnerable region.

Climate change and other global change drivers threaten plant diversity in mountains worldwide. A widely documented response to such environmental modifications is for plant species to change their ...elevational ranges. Range shifts are often idiosyncratic and difficult to generalize, partly due to variation in sampling methods. There is thus a need for a standardized monitoring strategy that can be applied across mountain regions to assess distribution changes and community turnover of native and non‐native plant species over space and time. Here, we present a conceptually intuitive and standardized protocol developed by the Mountain Invasion Research Network (MIREN) to systematically quantify global patterns of native and non‐native species distributions along elevation gradients and shifts arising from interactive effects of climate change and human disturbance. Usually repeated every five years, surveys consist of 20 sample sites located at equal elevation increments along three replicate roads per sampling region. At each site, three plots extend from the side of a mountain road into surrounding natural vegetation. The protocol has been successfully used in 18 regions worldwide from 2007 to present. Analyses of one point in time already generated some salient results, and revealed region‐specific elevational patterns of native plant species richness, but a globally consistent elevational decline in non‐native species richness. Non‐native plants were also more abundant directly adjacent to road edges, suggesting that disturbed roadsides serve as a vector for invasions into mountains. From the upcoming analyses of time series, even more exciting results can be expected, especially about range shifts. Implementing the protocol in more mountain regions globally would help to generate a more complete picture of how global change alters species distributions. This would inform conservation policy in mountain ecosystems, where some conservation policies remain poorly implemented.
We summarize the findings achieved with the standardized sampling protocol developed by the Mountain Invasion Research Network (MIREN) for monitoring the impact of global change on elevational plant species distributions. We intend to promote the use of the protocol to generate global insights into native and non‐native species responses to rapid global change in mountains.
We present a paleoenvironmental reconstruction for the mountain fringe between the South-Eastern Alps and the Northern Dinarides (NE-Italy/W-Slovenia) during the Last Glacial Maximum. We focused on a ...new sedimentary and paleoecological archive spanning the LGM acme, located in an aggrading, permanently flooded and ponded plain, dammed by an active fluvioglacial megafan. The ecosystem reconstruction, based on two high resolution pollen records, is supported by a rich plant macrofossil flora and constrained by a robust radiocarbon chronology between 26 and 22calka BP. We show evidence for persistence of boreal trees and of different open boreal forest types throughout the LGM at the south-eastern mountain fringe of the Alps and the Northern Dinarides. Fire frequency is responsible for high, oscillating forest openness. The paleobotanical record is discussed in the light of the ecogeographic diversity of the region. A belt formed by Swiss stone pine, larch and dwarf mountain pine on limestone bedrock, and accompanied by Spruce in the floodplain, extended uphill, while proximal outwash plain supported Scots pine and dwarf mountain pine. These differences arise from groundwater regimes rather than from local climate variability. A steep moisture gradient from the semiarid pedoclimatic regime prevailing in the Adriatic alluvial plain to the forested mountain fringe is related to the orographic rainout triggered by southern air circulation. Mesophytic broad-leaved forest trees did not withstand the LGM temperature extremes in zonal ecosystems at the Alpine–Dinaric fringe; however, the fossil evidence suggests a number of microrefugia in karstic and thermal spring habitats of the northern Adriatic.

Invasion by alien plant species may be rapid and aggressive, causing erosion of local biodiversity. This is particularly true for islands, where natural and anthropogenic corridors promote the rapid ...spread of invasive plants. Although evidence shows that corridors may facilitate plant invasions, the question of how their importance in the spread of alien species varies along environmental gradients deserves more attention. Here, we addressed this issue by examining diversity patterns (species richness of endemic, native and alien species) along and across roads, along an elevation gradient from sea-level up to 2050 m a.s.l. in Tenerife (Canary Islands, Spain), at multiple spatial scales. Species richness was assessed using a multi-scale sampling design consisting of 59 T-transects of 150 m à 2 m, along three major roads each placed over the whole elevation gradient. Each transect was composed of three sections of five plots each: Section 1 was located on the road edges, Section 2 at intermediate distance, and Section 3 far from the road edge, the latter representing the ânative communityâ less affected by road-specific disturbance. The effect of elevation and distance from roadsides was evaluated for the three groups of species (endemic, native and alien species), using parametric and non-parametric regression analyses as well as additive diversity partitioning. Differences among roads explained the majority of the variation in alien species richness and composition. Patterns in alien species richness were also affected by elevation, with a decline in richness with increasing elevation and no alien species recorded at high elevations. Elevation was the most important factor determining patterns in endemic and native species. These findings confirm that climate filtering reflected in varying patterns along elevational gradients is an important determinant of the richness of alien species (which are not adapted to high elevations), while anthropogenic pressures may explain the richness of alien species at low elevation.
