Understanding the factors that govern bone weathering is essential for interpreting faunal preservation and site formation processes in archaeological contexts. This study presents the firstfour-years of an actualistic l...

In this article, we present three case-studies of paleodietary reconstruction from Prehispanic agropastoralist societies located in the arid and semi-arid zones of North western Argentina. These three examples include th...

Among the South American Arid Diagonal (SAAD), the Argentine Arid Diagonal (AAD) constitutes an area with low precipitations (less than 500 mm) and extends from the north of the country (on the border with Bolivia), to P...

In semi-arid environments there is often a lack of data on hydrological variables that limits the ability to understand key hydrological processes. In response to this need, geomorphometric analysis is a quantitative app...

The Mapuche communities of the Argentinean extra-Andean Patagonia overcome extreme living conditions by applying subsistence strategy based on the utilization of different ethno-ecological units corresponding with differ...

Neltuma spp. (previously known as Prosopis spp.) are vital for ecological restoration and sustainable forestry in arid and semiarid environments. Although extensively studied, nursery techniques are still inconsistently ...

Biotic and abiotic stressors commonly co-occur in plant communities and influence interactions between plants. However, their combined effects on plant interactions have not been widely studied and are still unclear. Her...

Bacteroidales and viruses were contemporaneously measured during dry and wet weather conditions at a watershed-scale in a semi-arid watershed impacted by a mixture of agricultural runoff, municipal wastewater effluent an...

El estudio del xilema secundario de Bulnesia retama a lo largo de un gradiente de aridez permite encontrar variaciones entre los diferentes tipos celulares del xilema que predicen la tolerancia de esta especie a la aride...

The lesser rhea (family Rheidae) is a flightless large bird of South America, threatened due to habitat loss, hunting and egg collecting, with special concern in Northern Patagonia. Diet and food availability were estima...

In order to identify concordant distributions of endemic vascular plants in the Monte desert, we analyzed the distributional data of 180 species endemic to the Monte desert with the optimality criterion implemented in th...

Biological invasions are one of the most pervasive environmental threats to native ecosystems worldwide. The spontaneous spread of saltcedar is a particular threat to biodiversity conservation in arid and semiarid enviro...

Abstract Background Microhabitat heterogeneity plays a crucial role in shaping plant water use strategies and ecophysiological processes in arid ecosystems, yet little is known about the coupled response of leaf water is...

Abstract Freshwater scarcity and increasing energy demands pose serious challenges, and they are mainly experienced in arid environments and remote locations that are not grid-connected. In order to tackle these problems...

Abstract Groundwater provides a vital component of water supplies in semi-arid environments, wherein its quality directly influences ecosystem stability and human well-being. This investigation presents the first complet...

This research was aimed to analyse the genetic diversity of Geraeocormobius sylvarum, a forest-dwelling Neotropical harvestman with a disjunct distribution,separated by approximately 630 km of semi-arid environments. The...

Abstract Major concerns in view of global issues including population increase, climate change, food insecurity and declining cultivable land are ones of expansion. Ensuring nutritional security and helping to mitigate t...

Tayassuidae represent one of the first mammalian immigrants that entered South America during the “Great American Biotic Interchange.” However, the exact moment of its arrival for the first time in South America is c...

Knowledge of space use and territoriality of New World birds largely derives from studies in temperate North America and the tropics, whereas it remains poorly studied in temperate South America, particularly in arid env...

Tayassu pecari is widely distributed across the Neotropical region, from northern Argentina to south-eastern Mexico. However, its fossil record is scarce; it is recorded since the middle Pleistocene to Holocene in Argent...

This work aimed to analyze and classify the suitability of freshwater sources for irrigation in three large hydrographic regions of Southern Continental Patagonia: Coyle, Serrano, and Gallegos. In these regions, there is...

La historia geológica y climática del noroeste Argentino presenta fuertes cambios producto de los constantes procesos orogénicos y climáticos ocurridos durante el Neógeno y períodos glaciares e interglaciares del C...

En este trabajo se re-evalúa el modelo propuesto por Tonni y Politis en 1980 acerca de la distribución del guanaco durante el Holoceno tardío en el este de la región pampeana y se analizan las evidencias arqueológic...

Mycotoxins produced by Aspergillus species pose a major threat to food safety, particularly in warm and arid regions where environmental conditions favor fungal persistence and toxin biosynthesis. Aspergillus quadrilinea...
