“…Estos suelos abarcan una superficie importante en la provincia de Entre Ríos distribuidos en los departamentos Federal, Feliciano, Federación, y La Paz, y presentan altos niveles de arcilla expandible en el perfil generando dificultades en infiltración de agua, por lo tanto favorecen a la supervivencia de la colonia porque permiten sellar los orificios rápidamente (da SILVA y SCHOEREDER, 2008 En los departamentos ubicados al centro de la provincia como Nogoyá, La Paz, Villaguay, Concordia y Paraná, la probabilidad de encontrar alta presencia de nidos es menor (Cuadro 3). Esta disminución puede estar determinada por la intensa tasa de cambio de cobertura vegetal en los últimos años que provocó un reemplazo de las áreas boscosas por agricultura extensiva (SABATTINI y SABATTINI, 2012;BRIZUELA et al, 2013;SABATTINI, 2015). La probabilidad de no encontrar nidos de hormigas en los departamentos ubicados al sur es baja a nula (Cuadro 3) debido fundamentalmente a un descenso de la temperatura media anual y a la dominancia de un ecosistema menos diverso como la provincia fitogeográfica Pampeana (CABRERA, 1976).…”

ResumenLas especies de Atta tienen una amplia distribución geográfica tanto en el mundo como en la Argentina. El desarrollo de modelos de distribución de especies se encuentra en aumento, por la expansión de la información geoespacial de los recursos bióticos y abióticos. Los objetivos de este trabajo fueron determinar la distribución geográfica potencial de Atta vollenweideri Forel en la provincia de Entre Ríos e identificar los factores que limitan su distribución. La superficie del trabajo abarca 78.781 km 2 , y climáticamente se presenta como templado húmedo de llanura. Los registros de ocurrencia de la especies se obtuvieron de relevamientos de campo realizado en el año 2015 por medio de rutas nacionales, provinciales y caminos rurales, utilizando un receptor de posicionamiento global portátil. Se utilizaron 15 variables bioclimáticas del Worldclim que fueron estudiadas con el método de Máxima Entropía, mediante el programa MaxEnt. El 28% de la superficie provincial presenta una probabilidad alta (mayor al 50%) de condiciones bioclimáticas para la instalación de esta especie, mientras que el 30% presentan baja probabilidad de ocurrencia. La temperatura media del cuatrimestre más cálido explica el 35% del modelo, seguido de la precipitación del cuatrimestre más lluvioso, topografía, precipitación anual y la estacionalidad de la temperatura. El método de modelización y análisis espacial presenta respuestas adecuadas a lo esperable

“…In temperate regions of Europe and North America, an increase in the mass of planted forests has caused an increase in the equivalent carbon stock between 1 Gt to 3 Gt absorbed annually (Malhi et al, 1999). One aspect to highlight is that PA «El Caraya» have low impact from the clearing, probably due to the geographical location of the studied site, distant from paved routes, which makes insecurity in the activity of extraction of wood for sawmills (Sabattini, 2015;Sabattini et al, 2015a).…”

In forests, it is possible to sequester the carbon emitted by industrial activities, although global deforestation has recently increased considerably. Protected Areas make a significant contribution to mitigate negative effects of climate change. In this sense, the aim of this study is to estimate the carbon storage of the different types of subtropical native forests in the Protected Area «Estancia El Caraya» (hereinafter -PA «El Caraya»), located in the Mesopotamian Spinal. The study was carried out in the province of Entre Rios, Argentina. We evaluated the carbon stock in the soil and herbaceous, shrub and tree components of five various environments with native forests as the dominant biome. The soil component represented 81% of the carbon stock in native forest, while the remaining percentage is distributed in trees (11%), shrubs (6%), and herbaceous vegetation (2%). Native forest of PA «El Caraya» stores 0.974 t C × km -2 (3.56 t CO 2 × km -2 ), 39.4% less than the world average in this conservation category. These differences are due to the high heterogeneity of the natural environments in the world due to the very diverse ecological conditions. Proper management practice of subtropical native forests in the Spinal Mesopotamian contributes highly to reduction of carbon in atmosphere. Application of forest management techniques in Protected Areas allows obtaining sustainable forests that maximise the potential of this area.

“…On the other hand, it is called successional forest to those who are in the intermediate stages of plant succession. They have not still the stability of a native climax forest (Fontana & Sabattini, ; Sabattini, ; Sabattini, Wilson, Muzzachiodi, & Dorsch, ). At present, there are no specific criteria standardized in Argentina to classify successional stages.…”

Native forests are subject to variations in the structure of the different strata. These modifications can have a natural origin due to phenomena such as climate variation, fires, or floods; or they can be anthropic, due to the unsustainable use of forest resources. In general, according to the dominance of the different strata, the forests are classified as virgin, successional, or renoval. In the realization of inventories, there are situations in which the operator can offer a doubtful classification with a high degree of subjectivity. The purpose of this work has been to provide to technicians an objective tool for the classification of successional status in native forests. In this work, it has been found that there is a relationship between the presence of combinations of different plant species, both arboreal and shrub, related to the classification of forests. This relationship has been analyzed through the application of neural networks in two steps: First, a perceptron was applied, then a probabilistic neural network. The analysis through an artificial neuronal network of these two stages has allowed us to develop equations that through the presence/absence of 16 species allows to classify objectively the successional state. This analysis demonstrated an agreement of 83% with the subjective classification of trained field assessors.
