Significativa disminución de la superficie ocupada por los cuerpos de agua en los partidos de Adolfo Alsina y Puan
Full text linkEl sudoeste bonaerense está experimentando una severa sequía durante el presente 2023. De hecho, las precipitaciones mensuales arrojan valores inferiores al promedio histórico desde el mes de abril de dicho año. Una de las consecuencias de este fenómeno lo constituye la constante y considerable disminución de su superficie de los cuerpos bajo agua. En este informe se presentan los resultados correspondientes a la evolución del área ocupada por el agua en dos partidos de dicha área: Adolfo Alsina y Puan.EEA BordenaveFil: Marini, Mario Fabián.

Determinación de superficie de cultivos de invierno regada con pivot central en el partido de Coronel Suárez, campaña 2021
Full text linkSe ha efectuado un relevamiento de la superficie regada con pivot central en el partido de Coronel Suárez para la campaña agrícola 2021. Para ello se han empleado técnicas de teledetección y SIG utilizando el satélite Landsat 8 - Operational Land Imager (OLI) en virtud de su óptima disponibilidad y adecuada resolución espacial. El objetivo de este artículo es el de efectuar un relevamiento de lotes que actualmente se encuentran empleando este sistema de riego en cultivos invernales.EEA BordenaveFil: Marini, Mario Fabián.

Termites of the monastery of saint catherine (Sinai, Egypt)
No full textThe Greek Orthodox Monastery of Saint Catherine is the oldest continuously inhabited Christian Monastery, and is included in a UNESCO World Heritage Site due to its cultural importance. In 2001, termite-related damage was observed in some of the Monastery buildings and in a church in the nearby village of Saint Catherine. The identification of the termite species found in the area of the Monastery was a priority for planning pest control activities. Morphological analysis revealed the presence of two species of higher termite (Termitidae): Microcerotermes eugnathus Silvestri and Amitermes vilis (Hagen), the latter new to Egypt. Because genetic data on Microcerotermes and Amitermes species from this area are lacking, we also sequenced mitochondrial DNA genes (COII and 16S) of these species and of two additional species, Microcerotermes palestinensis Spaeth and Amitermes desertorum (Desneux), occurring in nearby areas. The systematics of Microcerotermes species in Africa and the Levant is still confused, some synonymies are suspected, and recent revisions are lacking. As for M. eugnathus, no diagnostic differences with the more recently described M. palestinensis are known, and we suspect that M. palestinensis might be a junior synonym of M. eugnathus. In the Monastery, termite-related damage was mainly limited to structural wood and scarce objects of historical value. Termite monitoring and control would be necessary to prevent serious damage to objects of important historical value, especially in consideration of the recent increase in rainfall in the area of the Monastery, which could favour termite abundance and activity
A dark-necked drywood termite (Isoptera: Kalotermitidae) in Italy: description of Kalotermes italicus sp. nov.
No full textThe yellow-necked drywood termite, Kalotermes flavicollis (F.), so called due to the Yellow pronotum of its alates, is the only species in the genus Kalotermes known for Europe. In some Italian localities, K. flavicollis swarms can contain a small proportion of alates with a dark pronotum, but otherwise not different from the normally colored K. flavicollis. This color variation was described by G. Becker in 1955 as Kalotermes flavicollis var. fuscicollis.
During collecting trips in central Italy, we found in Grosseto Marina (Tuscany) a Kalotermes population whose alates all have a very dark pronotum. Compared with K. flavicollis alates, Grosseto alates also have paler wings and smaller arolia. Grosseto soldiers have eyes smaller than those of K. flavicollis soldiers. Kalotermes sp. form Grosseto also differs morphologically from the other Kalotermes species known for the circum-Mediterranean lands.
The population from Grosseto has mitochondrial DNA sequences (a partial sequence of the control region and a fragment including a portion of COI, tRNA-Leu and a portion of COI) quite different from K. flavicollis (p-distance: 5.6-7.3%). Some Kalotermes populations from Tuscany and Marche, morphologically classifiable as K. flavicollis, have sequences similar to those of Grosseto Kalotermes (p-distance: 0.1-1.0%). These populations are possibly hybrids between K. flavicollis and Kalotermes sp. from Grosseto. Because of its morphologic and genetic distinctive features, we describe Kalotermes sp. from Grosseto as Kalotermes italicus sp. nov
Description of a new termite species from Cyprus and the Aegean area: Reticulitermes aegeus sp. nov.
No full textReticulitermes aegeus sp. nov. (Rhinotermitidae) is described, based on samples of alates and soldiers collected on the island of Cyprus. The range of the species includes the island of Lošinj (Croatia), north-eastern Greece (Halkidiki and north-eastern Greece), Eastern Peloponnese, Northern Turkey, Crete, Cyprus and Amorgos (Cyclades Islands). The ascertained range of R. aegeus does not overlap with the ranges of other species occurring in the eastern Mediterranean lands. From the phylogenetic point of view, R. aegeus belongs to the eastern Mediterranean Reticulitermes clade, that also includes R. urbis, R. balkanensis and R. clypeatus, as well as taxa not yet described from Turkey and the island of Samos. R. aegeus is genetically distinct from other eastern Mediterranean Reticulitermes species, while its morphological characters do not allow a reliable diagnosis without further support. DNA analysis provides such corroboration
Computed Tomography of dental arches with dedicated software: current state of applications.
No full textSince the introduction of the "Dentascan" reconstruction program, the use of CT in the field of odontostomatology has attracted growing interest from both radiologists and dentists. Over the years, the potential applications of Dentascan have extended from the management of implantology-related issues to the study of all jaw bone diseases relevant to dentists. This paper describes the technical aspects and current diagnostic capabilities of computed tomography of the dental arches with dedicated software, by presenting a wide selection of case studies
