Se utilizó un método de mapeo basado en la localización de las edificaciones y la disponibilidad de vegetación combustible. Se trabajó sobre una capa raster base (10 x 10 m) y para cada píxel se calculó la densidad de edificaciones en una circunferencia de 500 m de radio, utilizando una ventana móvil. La IUR ocupa el 14,8% del área de estudio. Sin embargo, alberga 143.700 viviendas, lo que representa el 52% de la totalidad de las edificaciones del área de estudio. Asimismo, 6.769 viviendas se ubicaron en áreas que sufrieron incendios entre 1999 y 2011, de las cuales el 63% se ubicó en áreas de IUR. Por tal motivo, es imprescindible adoptar medidas de manejo destinadas a minimizar el riesgo y planificar el desarrollo urbanístico futuro.Fil: Argañaraz, Juan P.

Instantaneous Kinematics and Singularities of Two Types of Under-Actuated Parallel Wrists
No full textS-(nS)PU-SPU and S-(nS)PU-2SPU are two out of three types of under-actuated wrists that are generated from the “ordinary” wrists of type S-3SPU (fully-parallel wrists), by replacing a spherical pair (S) with a nonholonomic spherical pair (nS) according to the rules stated in [1]. Position analysis, controllability, and path planning of these two wrist types have been addressed and solved in two previous papers [2, 3] of this author. Their kinetostatics and singularity analysis have not been addressed, yet; and they are studied in this paper.

Fire regime, climate, and vegetation in the Sierras de Córdoba, Argentina
No full textWildfires are a primary disturbance in the Sierras de Córdoba, Argentina,with approximately 2152000 ha burned between 1993 and 2012. However,little is known about the spatial and temporal patterns of fires and theirrelationship with climate and vegetation in this area. Such information isof great value for fire risk assessment and the development of strategies forfire management. Our main objective was to analyze fire activity in four sierranranges, assessing which weather and climate conditions were mostly relatedto fire activity, and which land cover types were mostly burned. Weused a fire database of mid-high spatial resolution and a land cover mapderived from Landsat imagery. Fire regimes were different among the differentsierran ranges. The Sierras Chicas range was the most affected byfires, with the largest number of fire events, burned area, and fire frequency.Although large fires represented 3% to 5% of fire events, they accountedfor 60% to 86% of total burned area in different sierran ranges. Sierrasof lower elevation had a winter seasonality of fires, while sierras ofhigher elevation had a winter-spring or spring fire seasonality. The number offire events was positively correlated with preceding periods that were wetterthan normal, while the burned area was mainly associated with midtermweather conditions. Fires occurred mainly in grasslands and shrublands,but the area of burned forests was important, too. Our results will be usefulto determine the times and conditions in which fire risk is highest, and also toidentify where preventive efforts should be focused.Fil: Argañaraz, Juan Pablo.

Unraveling resilience amidst degradation: Recurring loss of freshwater marshes in the Paraná River Delta, Argentina
No full textWetland ecosystems have experienced several ecological and hydrological impacts in recent decades determined by human activities and natural disturbances. The Lower Delta of the Paraná River, one of the most important wetland ecosystems of South America, has seen significant losses in both the structural and functional components of wetland vegetation. These losses promoted not only a widespread conversion of freshwater marshes into grasslands between 1997 and 2013, but also a decline in ecosystem functional diversity between 2001 and 2015. These processes manifested as abrupt shifts in long-term vegetation dynamics, a distorted, transient, spatially heterogeneous relationship with the hydrologic regime, and altered plant communities. However, recent field observations (2015–2023) have partially challenged previous findings and assumptions. Thus, we ask whether previously observed wetland losses are part of a long-term periodic process, rather than a permanent change. To address this question, we studied land use and land cover conversions through an object-based supervised classification of yearly Landsat composites between 1985 and 2023, trained on 935 ground-truth points. To study the spatial and temporal patterns of wetland gain and loss, we implemented an Intensity Analysis (IA), as well as analyses that capture frequency-specific variations and identify significant shifts in linear trends. We produced a total of 39 land cover maps. The IA revealed non-stationarity at all levels of analysis: interval, category, and transition. The study area exhibited resilient patterns through significant and increasingly short-term, periodic dynamics guiding the gain and loss of freshwater marshes. On the opposite, long-term, negative trends depicted an absolute, sustained loss. These contrasting patterns suggest that despite experiencing absolute loss and degradation, wetland ecosystems thrive by exhibiting transient recovery or adaptation mechanisms. Our study unraveled the complexity of wetland ecosystem dynamics, emphasizing how resilience and degradation interplay in the context of land use intensification.Instituto de Fisiología y Recursos Genéticos VegetalesFil: Aquino, Diego Sebastián.

Disentangling the effects of hydro-climatic factors and land use intensification on wetland vegetation dynamics in the Lower Delta of the Paraná River
No full textThe non-insular portion of the Lower Delta of the Paraná River is part of the largest mosaic of wetlands in Argentina. However, it is being altered by intensification of cattle grazing and the increasingly rapid implementation of water management infrastructure. In this context, studying the relationship between hydro-climatic variables and vegetation growth is urgent to ensure sound management and conservation. To overcome the limitation of high cloud cover in the area which has hampered the construction of regularly spaced high-resolution time series, we implemented the recently developed spatio-temporal vegetation index image fusion model (STVIFM). In order to understand the relationship between vegetation growth and hydro-climatic factors, we performed pixel-wise correlation analyses between the newly synthesized monthly (30m) NDVI time series and hydro-climatic variables. Then, we tested whether water control infrastructure alters these relationships. Based on the accurate performance of STVIFM, we provide quantitative and spatially accurate evidence on the positive, complementary and heterogeneous relationships between vegetation growth, temperature, rainfall and the flood pulse. Our results show that water management infrastructure decouples certain areas from its natural hydrological regime, decreasing water availability and altering vegetation growth dynamics. In this context, urgent action is needed aimed towards implementing land planning measures that consider the natural variability and hydrologic regime of the system while balancing production and conservation.Fil: Aquino, Diego Sebastián.

Ecological condition indicators for dry forest: Forest structure variables estimation with NDVI texture metrics and SAR variables
No full textThe ecological condition of forest ecosystems is degraded. Limited prior research in vegetation has focused on monitoring ecological condition levels in dry forest at fine scale. We proposed a novel approach to obtain accurate indicators of the ecological condition of the Chaco Serrano forest (Córdoba, Argentina) by estimating forest structure variables (canopy cover (CC), diameter breast height (DBH_sum), number of woody individuals (NW) and two first axes of a principal component analysis (PC1 and PC2)) as a measure of forest degradation. To achieve this, first the correlation with two complementary groups of remote sensing derived data (texture metrics over Normalised difference vegetation index and SAR-derived data) was explored. Then, General linear models (GLM) were constructed using the most correlated remote sensing derived variables with forest structure variables as predictor variables. The best estimation was obtained to CC (r2=0.58, rmse=14,5%), followed by DBHsum (r2=0.37, rmse=156.6) and NW (r2=0.22, rmse=14.6), with an spatial arrangement consistent with field observations. Moreover, CC estimation was more accurate than those at regional and global scale, and highlights the importance of developing local models in areas that exhibit high ecological, geological, and human heterogeneity. In addition, other forest variables could also be evaluated, like floristic composition or others associated with functioning. Results offer valuable insights for developing management strategies suitable for each condition, and for future studies regarding the relationship of the mentioned condition and associated natural and anthropic factors.Instituto de Fisiología y Recursos Genéticos VegetalesFil: Alvarez, María Paula.
