Water scarcity and soil fertility loss are major limitations for agricultural production. This study evaluated the effects of walnut shell biochar (WSB) fertilizer on growth lettuce (Lactuca sativa L. “Gran rapid”) in hydroponic conventional systems. WSB alone + were applied at different mass ratios to (0, 5, 10, 15%) system substrate 20%) system. Agronomic parameters such as fresh weight, dry leaf area index, number leaves evaluated. The results showed that addition improved both In...
This study investigated the phytotoxicity of agro-industrial wastes (almond, walnut, pistachio and peanut shells, asparagus spears, brewer’s spent grain) their biochar through germination bioassays in several horticultural species: green pea, lettuce, radish, arugula. Biowaste was pyrolyzed under controlled conditions to produce biochar, both biowaste were characterized. Germination bioassay conducted using seeds exposed different dilutions aqueous extract (0, 50, 100%). percentage, seed...
This study presents an analysis of NO2 and CO emissions in Argentina, utilizing remote sensing data. research aims to determine the spatiotemporal distribution from 2019 2021. It examines influence land use cover on using various climatic, anthropic, natural indicators. The year with highest concentration was 2020. exhibited concentrations built-up urban areas croplands, notably impacting capital city northern region Buenos Aires province. Also, influenced by anthropic variable distances...
Anopheles (Nyssorhynchus) aquasalis, is the main coastal vector of malaria from northeastern Venezuela to southeastern Brazil. Several authors have argued that An. aquasalis a highly polymorphic species while others indicated it complex closely related species. This investigation compared morphology eggs Sinamaica (Zulia State) and Yaguaraparo (Sucre State), west east Venezuela, respectively. We were able separate two localities using discriminant analyses based on ratios percentages...
Two new stonefly species, Anacroneuria segnini Stark and Maldonado sp. n. A. cacute are described from Venezuela. Nymphal descriptions based on reared specimens given for segnini, muesca Stark, paleta two unassociated females, an additional species being by colleagues.
Dominant woody vegetation in arid ecosystems supports different species of plants and animals largely dependent on the existence these habitats for their survival.The chica (Ramorinoa girolae) is a leguminous tree endemic to central-western Argentina categorized as vulnerable.We evaluated 1) richness plants, birds mammals associated with habitat under its canopy, 2) whether related morphological attributes features 3) behavior displayed by mammals.We recorded presence/absence canopy 19 trees...
Urban parks and cemeteries constitute hot spots of bird diversity in urban areas. However, the seasonal dynamics their communities have been scarcely explored at large scales. This study aims to analyze drivers assemblage seasonality comparing assemblages during breeding non-breeding seasons Neotropical Region. Since less human disturbance than parks, we expected differences community between habitats. The change species composition was partitioned into turnover nestedness. At scales,...
Herbivorous subterranean rodents, such as Ctenomys mendocinus (tuco-tuco), have a significant impact on vegetation cover and composition. This study aimed to examine the indirect influence of tuco-tucos bird populations assemblages in southernmost region desert Puna. In shrub-steppe community, at an altitude between 3,000 3,100 m.a.s.l., surveys were conducted from February 2001 October 2004. Transects 50 m length 40 width established: 56 located highly disturbed patches 53 with low...
This article focuses on identifying risk factors through the knowledge, perceptions, and prevention practices of population regarding rock pigeon vector Chagas disease (vinchucas) in an urban area Argentina. The study used interviews focal groups, family nuclei with nearby nesting sites without sites. Among results, some that contribute to infestation vinchucas houses were identified, such as presence pigeon, frequency cleaning nests fumigation. We show people kept their clean routinely...
Abstract In a city located in desert environment (Tulum Valley, Argentina) we proposed to assess the coldest and warmest periods (1) urban cold/heat island (UCI/UHI) phenomenon; 2) which driving factors currently affect Land Surface Temperature (LST). study area, selected 50 points for class 49 rural class. The LST data was obtained from Landsat 5 TM y 8 OLI/TIRS, 1988, 2000, 2010, 2021 years. As driver factors, assessed median (med) standard deviation (sd) of NDVI (Normalized Difference...
