| description | Background and Aims: Biocrusts play an essential role on the earth’s surface and have a direct influence on soil parameters. Their effects on soil temperature are considered one of the most important because they affect ecological and hydrological processes, as well as the diversity of natural ecosystems. Although there are several studies concerning biocrust effects on the soil surface, investigations about the effect of the biocrust on soil temperature are still scarce. Our objective was to evaluate the influence of biocrusts on soil temperature conditions in drylands of central-western Argentina. Methods: Temperature values were recorded in the Monte phytogeographic region in the central-western part of Argentina, in three sites, during the dry and wet seasons in 2017-2018. We collected samples from a total of 30 randomly selected plots. We recorded daily temperatures values in two paired plots with crusted and uncrusted zones using a calibrated data logger Ibutton. The sampling took 18 days in total, three days on each site.Key results: Our results indicate that biocrusts produce a change in micro-soil temperatures. Areas in which biocrusts are present show a temperature reduction both in the wet and dry seasons. This effect is observed in the three studied sites. Temperature reduction varies according to the time of the day, study site and season. The morning, noon, and afternoon recorded the highest mean temperatures.Conclusions: The presence of biocrusts reduces soil temperatures in drylands of central-western Argentina. Large differences in mean temperature values between crusted and uncrusted zones were observed. The thermal reduction was more notorious in the hyper-arid site. How they affect their surrounding environment can be related to multiple factors, such as the composition of the microphytic community, the local climate and environmental conditions. |

Antecedentes y Objetivos: Las costras biológicas del suelo juegan un papel esencial en la superficie terrestre y tienen una influencia directa en los parámetros del suelo. Sus efectos sobre la temperatura del suelo se consideran uno de los más importantes debido a que afectan los procesos ecológicos e hidrológicos, así como la diversidad de los ecosistemas naturales. Aunque existen varios estudios sobre los efectos de la costra biológica en la superficie del suelo, las investigaciones sobre el efecto de la costra biológica en la temperatura del suelo aún son escasas. Nuestro objetivo fue evaluar la influencia de las costras biológicas en las condiciones de temperatura del suelo en zonas áridas del centro-oeste de Argentina.Métodos: Se registraron valores de temperatura en la región fitogeográfica del Monte en la parte centro-oeste de Argentina, en tres sitios, durante las estaciones seca y húmeda de 2017 y 2018. Colectamos muestras de un total de 30 parcelas seleccionadas al azar. Registramos valores de temperatura diarios en dos parcelas emparejadas con zonas con costras biológicas y sin costras biológicas utilizando un registrador de datos calibrado tipo Ibutton. El muestreo se llevó a cabo durante un total de 18 días, tres días en cada sitio. Resultados claves: Nuestros resultados indican que las costras biológicas producen un cambio en las temperaturas microambientales del suelo. Las áreas donde están presentes las costras biológicas muestran una reducción de la temperatura tanto en las estaciones húmedas como en las secas. Este efecto se observa en los tres sitios estudiados. La reducción de la temperatura varía de acuerdo con la hora del día, el sitio de estudio y la estación del año. La mañana, el mediodía y la tarde registraron las temperaturas medias más altas.Conclusiones: La presencia de costras biológicas reduce las temperaturas del suelo en las zonas áridas del centro-oeste de Argentina. Se observaron grandes diferencias en los valores medios de temperatura entre las zonas con costras biológicas y las zonas sin costras biológicas. La reducción térmica fue más notable en el sitio hiperárido. Cómo afectan su entorno circundante puede estar relacionado con múltiples factores, como la composición de la comunidad microfítica, el clima local y las condiciones ambientales.
