How are riparian plants distributed along the riverbank topographic gradient in Mediterranean rivers? Application to minimally altered river stretches in Southern Spain.

Species structure and composition in Mediterranean riparian forests are determined by hydrological features, longitudinal zonation, and riverbank topography. This study assesses the distribution of four native riparian plants along the riverbank topographic gradient in three river stretches in southern Spain, with special emphasis on the occupation of adult and young feet of each species. The studied stretches suffered minimal human disturbances, displayed semi-arid conditions, and had wide riparian areas to allow the development of the target species: black alder (Alnus glutinosa), salvia leaf willow (Salix salviifolia), narrow-leafed ash (Fraxinus angustifolia), and oleander (Nerium oleander). Thalweg height was used to define the riverbank topographic gradient. The results showed a preferential zone for black alder and salvia leaf willow in the range of 0-150 cm from the channel thalweg, with adult alders and willows being more common between 51 and 150 cm and young alders being more common under 50 cm. Conversely, narrow-leafed ash and oleander were much more frequent, and showed greater development, in the ranges of 151-200 cm and 201-250 cm, respectively, whereas the young feet of both species covered the entire topographic range. Adult feet of the four species were spatially segregated along the riverbank topographic gradient, indicating their differential ability to cope with water stress from the non-tolerant alders and willows to more tolerant narrow-leafed ash trees and oleanders. Young feet, however, showed a strategy more closely linked to the initial availability of colonisation sites within riparian areas to the dispersion strategy of each species and to the distribution of adult feet. In Mediterranean areas, where riparian management has traditionally faced great challenges, the incorporation of species preferences along riverbank gradients could improve the performance of restoration projects

Distribución espacial del ensamblaje de Macroinvertebrados asociada al litoral rocoso del Pnn Ensenada de Utría, Pacífico Colombiano.

La distribución de los organismos que habitan en los litorales rocosos del mundo es afectada por diversos factores físicos que varían con respecto a la altura intermareal, la cual se hace particularmente amplia en la costa pacífi ca colombiana. Debido a esto se estudió cómo la localidad, la exposición al oleaje y la posición en la zona intermareal afectan la riqueza, la abundancia y la distribución de las especies más representativas que se encuentran en los litorales rocosos del Parque Nacional Natural Utría (PNNU). Las especies más abundantes fueron los gasterópodos Nerita scabricosta, N. funiculata, Littorina modesta, L. aspera y el cirripedio Cthamalus panamensis, y mostraron un claro patrón de segregación dentro de la zona intermareal. La exposición al ojeaje dentro de las pequeñas bahías de las tres localidades infl uyó en la riqueza y el promedio de especies encontradas, pero no en la abundancia. Por otro lado, el patrón de distribución observado en las especies más abundantes se explica principalmente por las características intrínsecas y su capacidad para colonizar áreas específi cas a lo largo del litoral rocoso. Abstract The distribution of organisms that inhabit the rocky shores of the world is affected by several physical factors that vary with respect to the intertidal height, which is particularly wide in the Pacifi c coast of Colombia. This study shows the effect of location, wave exposure and position in the intertidal zone on the richness, abundance and distribution of the most distinctive species found on the rocky shorelines of The Utría National Park ( PNNU ), Colombia. The most abundant species, gastropods Nerita scabricosta, N. funiculata modest Littorina, L. aspera and barnacle Cthamalus panamensis, showed a clear pattern of segregation within the intertidal zone. Wave exposure in the bays of the three locations infl uenced the richness and average but not the abundance of the species. For the most abundant species, the observed distribution pattern is mainly due to intrinsic features and their ability to colonize specifi c areas along the rocky shoreline

Strategies for the Development of the Value of the Mining-Industrial heritage of the Zaruma -Portovelo, Ecuador, in the Context of a Geopark Project

The enhancement of heritage resources helps to promote conservation, contributes to more significant and better protection, and favors the efficient use of these resources. Many heritage works and liabilities linked to mining activity are abandoned, causing the deterioration of heritage resources that may become environmental liabilities over time. This work aims to develop strategies for the development of the Mining-Industrial heritages through participatory methods for geomining enhancement and development of places in the Zaruma-Portovelo area. The proposed methodology consists of: (i) The creation and development of a database with several publications and documents that register the Mining-Industrial heritage sites; (ii) The assessment of mining-industrial sites based on criteria or methodologies proposed by other authors; (iii) Focal group work considering: (a) The identification and cataloging geosites of interest, (b) The creation and/or development of museums, tourist mines, mineral routes or geoparks in which the natural and geological-mining factors complement each other and (iv) SWOT analysis and matrix which provides several strategies for value-making of geomining heritage and its promotion in the development of geotourism in a project proposal for Zaruma and its surroundings. In conclusion, this work includes twelve unified mining sites in the Proposal for Geopark ‘Ruta del Oro,’ as a strategy to guarantee the conservation of heritage values and contribute to local development and geotourism

Cyber-physical framework for laparoscopic surgery

[EN] This work develops the implementation of a cyber-physical framework for laparoscopic surgery that allows for the use of a surgical simulator with a robotic arm, in order to facilitate learning and research with this type of systems. A configuration for every element in the operation room that allows all the functional restrictions to be fulfilled is proposed and validated. An inverse kinematic model for the redundant robotic arm is also implemented, which returns the most appropriate solution that ensures compliance with these restrictions. Finally, an interface is developed in MATLAB that allows future work to be carried out using this framework, presenting a simple application as an example of use.[ES] Este trabajo desarrolla la implantación de un entorno de trabajo cíber-físico para cirugía laparoscópica que permite utilizar un simulador quirúrgico con un brazo robótico, para así facilitar el aprendizaje y la investigación con este tipo de sistemas. Se propone y valida una configuración para cada uno de los elementos del quirófano que permite cumplir todas las restricciones funcionales. También se implanta un Modelo Cinemático Inverso para el brazo robótico redundante que devuelve la solución más adecuada que asegura el cumplimiento de estas restricciones. El entorno de trabajo se ha implementado haciendo uso de ROS y MATLAB, realizando una serie de pruebas a fin de validar el desarrollo de aplicaciones utilizando este framework.Proyecto Sistema quirúrgico ciberfísico para abordaje laparoscópico" (PY20-00738), grupo de investigación de Robótica Médica del Dpto de Ingeniería de Sistemas y Automática de la Universidad de MálagaHerrera-López, JM.; Galán-Cuenca, Á.; García-Morales, I.; Rollón, M.; Rivas-Blanco, I.; Muñoz, VF.

Ayotzinapa y la crisis del estado neoliberal mexicano

¿Qué pasó en Ayotzinapa? Es la pregunta que surgió el 26 de septiembre de 2014, que no encuentra una respuesta satisfactoria pese a la intervención de actores de distintas instancias, niveles y nacionalidades, y al esbozo de múltiples hipótesis sobre los enfrentamientos registrados en Iguala, Guerrero, que derivaron en la muerte de varias personas y la desaparición de 43 estudiantes de la Normal Rural “Isidro Burgos”, en una tragedia que evidenció la crisis que atraviesa el estado mexicano y que afecta a todo el país. A partir de lo acontecido en Ayotzinapa y con base en la teoría general de los campos de Pierre Bourdieu y su propuesta de análisis teórico metodológico sobre el estado, en esta obra se realiza un análisis de la práctica sistemática y generalizada de las desapariciones forzadas en México, con el fin de ofrecer otra manera de comprender el entretejido político–económico–social que hace posible este grave fenómeno, que desgarra tanto a familias como a la comunidad. La herida abierta por Ayotzinapa sangra y el objetivo último de este libro es contribuir a evitar que se cierre en tanto no se responda la interrogante de qué pasó ahí y que crímenes de lesa humanidad como este sigan aconteciendo en México.ITESO, A.C

SilvAdapt.Net: A Site-Based Network of Adaptive Forest Management Related to Climate Change in Spain

[EN] Adaptive forest management (AFM) is an urgent need because of the uncertainty regarding how changes in the climate will affect the structure, composition and function of forests during the next decades. Current research initiatives for the long-term monitoring of impacts of silviculture are scattered and not integrated into research networks, with the consequent losses of opportunities and capacity for action. To increase the scientific and practical impacts of these experiences, it is necessary to establish logical frameworks that harmonize the information and help us to define the most appropriate treatments. In this context, a number of research groups in Spain have produced research achievements and know-how during the last decades that can allow for the improvement in AFM. These groups address the issue of AFM from different fields, such as ecophysiology, ecohydrology and forest ecology, thus resulting in valuable but dispersed expertise. The main objective of this work is to introduce a comprehensive strategy aimed to study the implementation of AFM in Spain. As a first step, a network of 34 experimental sites managed by 14 different research groups is proposed and justified. As a second step, the most important AFM impacts on Mediterranean pines, as one of the most extended natural and planted forest types in Spain, are presented. Finally, open questions dealing with key aspects when attempting to implement an AFM framework are discussed. This study is expected to contribute to better outlining the procedures and steps needed to implement regional frameworks for AFM.A.J.

A code to Make Your Own Synthetic ObservaTIonS (MYOSOTIS)

We introduce our new code MYOSOTIS (Make Your Own Synthetic ObservaTIonS) which is designed to produce synthetic observations from simulated clusters. The code can synthesize observations from both ground-and spaced-based observatories, for a range of different filters, observational conditions and angular/spectral resolution. In this paper, we highlight some of the features of MYOSOTIS, creating synthetic observations from young massive star clusters. Our model clusters are simulated using NBODY6 code and have different total masses, halfmass radii, and binary fractions. The synthetic observations are made at the age of 2 Myr with Solar metallicity and under different extinction conditions. For each cluster, we create synthetic images of the Hubble Space Telescope (HST) in the visible (WFPC2/F555W) as well as Very Large Telescopes in the nearIR (SPHERE/IRDIS/Ks). We show how MYOSOTIS can be used to look at mass function (MF) determinations. For this aim we re-estimate stellar masses using a photometric analysis on the synthetic images. The synthetic MF slopes are compared to their actual values. Our photometric analysis demonstrate that depending on the adopted filter, extinction, angular resolution, and pixel sampling of the instruments, the power-law index of the underlying MFs can be shallower than the observed ones by at least ±0.25 dex which is in agreement with the observed discrepancies reported in the literature, specially for young star clusters
