Abstract Tracer‐aided studies to understand plant water uptake sources and dynamics in tropical ecosystems are limited. Here, we report the analysis of dry season source patterns five unique Costa Rica across altitudinal (<150–3,400 m asl) latitudinal (Caribbean Pacific slopes) gradients: evergreen seasonal rainforests, cloud forest, Páramo forest. Soil samples were collected during 2021. Plant soil extractions conducted using centrifugation. Stem extracted volume stem total content calculated via gravimetric analysis. Water contributions estimated a Bayesian mixing model. Isotope ratios stems exhibited strong meteoric origin. Enrichment trends only detected cactus within forest ecosystem. profiles revealed nearly uniform isotopic profiles; however, depletion trend was observed ecosystem below 25 cm. More enriched compositions reported for volumes above ~20% ( adj. r 2 = 0.34, p < 0.01). The most prominent rainforest (74.0%), (86.4%) (66.0%) corresponded well‐mixed water. In ecosystem, recent rainfall produced by trade wind incursions resulted significant (61.9%), whereas mean annual precipitation (38.6%) baseflow (33.1%) dominant sources. latter highlights prevalence distinct between cold front (near‐surface storage) more moisture season, revealing ecohydrological processing previously unknown this region.

High mountain areas are critical for water security and natural hazard dynamics, as well glacier ecosystem conservation in a warming world. We present brief account of the methodological steps geomorphological mapping areas, including required scale, legends, technology, software. analyze best imagery sources their combination with fieldwork geographical information systems (GIS), performing accurate cartography. In addition, we two case studies which apply several methods described previously. Firstly, carried out classical digital Cerro Chirripó (Talamanca Range). Secondly, studied Reserva Biológica Alberto Manuel Brenes (Central Volcanic Range), where used UAVs to map high-resolution fluvial geomorphology. This framework is suitable future surveys worldwide. Moreover, can give ideas on application these approaches different mountainous environments.

Precipitation plays a crucial role in the natural hydrological cycle. Understanding spatial and temporal variations of precipitation isotopes is essential for identifying hydrological, meteorological, ecological processes. In high mountain areas with arid semi-arid conditions, especially regions endorheic basins, portion that infiltrates groundwater as primary source water recharge. However, estimating this recharge challenging prone to uncertainty. The main objective study was implement robust detailed methodology analyze influence meteorological variables origin moisture sources on stable isotopic composition (δ18O δ2H) precipitation.
