ABSTRACT Despite their critical role as freshwater resources and vulnerability to anthropogenic pressures, our knowledge of the ecohydrology tropical montane cloud forests remains limited. Here, we use a dual stable isotope approach (δ 2 H δ 18 O) trace water inputs, fluxes, pools through seasonally dry forest in central Veracruz, Mexico. We found strong seasonal variation composition precipitation inputs ~130‰ O ~18‰), with significantly more depleted wet‐season values compared dry‐season...
Most studies to date in the humid tropics have described a similar pattern of rapid translation rainfall runoff via overland flow and shallow subsurface stormflow. However, study sites been few overall, one particular system has received very little attention so far: tropical montane cloud forests (TMCF) on volcanic substrate. While TMCFs provide critical ecosystem services, our understanding generation processes these environments is limited. Here, we present aimed at identifying dominant...
Abstract. While tropical montane cloud forests (TMCF) provide critical hydrological services to downstream regions throughout much of the humid tropics, catchment hydrology and impacts associated with forest conversion in these ecosystems remain poorly understood. Here, we compare annual, seasonal event-scale streamflow patterns runoff generation processes three neighbouring headwater catchments central Veracruz (eastern Mexico) similar pedological geological characteristics, but different...
Present and future climatic trends are expected to markedly alter water fluxes stores in the hydrologic cycle.In addition, demand continues grow due increased human use a growing population.Sustainably managing resources requires thorough understanding of storage flow natural, agricultural, urban ecosystems.Measurements stable isotopes (hydrogen oxygen) cycle (atmosphere, soils, plants, surface water, groundwater) can provide information on transport pathways, sourcing, dynamics, ages, pools...
Land use/cover (LUC) and changes between 1990 2003 in a tropical mountainous watershed were analysed with Landsat TM images using GIS‐RS approach. The La Antigua River upper catchment is 1325 km2, biodiverse hydrological region central Veracruz, Mexico. A large set of training pixels was used to optimize the representation environmental heterogeneity. Classification accuracy assessed spectral field‐checked error matrices. Overall classification for (78.2%) (79.7%) satisfactory. Ancillary...
Abstract. Stream water mean transit time (MTT) is a fundamental hydrologic parameter that integrates the distribution of sources, flow paths, and storages present in catchments. However, tropics little MTT work has been carried out, despite its usefulness for providing important information on watershed functioning at different spatial scales (largely) ungauged basins. In particular, very few studies have quantified stream MTTs or related these to catchment characteristics tropical montane...
Abstract. Globally, coffee has become one of the most sensitive commercial crops, being affected by climate change. Arabica (Coffea arabica) grows in traditionally shaded agroforestry systems tropical regions and accounts for ∼70 % production worldwide. Nevertheless, interaction between plant soil water sources these plantations remains poorly understood. To investigate functional response dominant shade tree species (C. arabica var. typica) plants to different availability conditions, we...

Abstract Tropical montane cloud forests (TMCF) are recognized for their capacity to maintain high dry‐season baseflow and a host of other ecosystem services. Substantial areas TMCF have been converted pasture crops such as coffee, while in TCMF recovering. However, little is known about the effects this complex dynamic on catchment hydrology. We investigated effect land use rainfall‐runoff response five neighbouring headwater micro‐catchments central Veracruz, Mexico, dominated by either...
The provision and regulation of water flows in catchments is probably the most important ecosystem service cloud forests; however, its hydrological behavior impacts associated with forest conversion remain very poorly understood.The present study aimed at evaluating effects land use change for a region on volcanic soils Veracruz, Mexico.For this, micrometeorological, ecophysiological measurements combined stable isotope data were used.The findings showed higher annual yields pasture, as well...
Citizen science data can fundamentally advance the natural sciences, but concerns remain about its accuracy, reliability, and overall value. While some studies have evaluated accuracy of citizen data, few also assessed potential contribution to conservation policy. This study focuses on rainfall collection, with four goals: (1) examine motivations of, barriers for, volunteer participation in science; (2) evaluate comparison automatic rain gauge data; (3) incorporate datasets into...

Abstract Rainfall retention and runoff detention are likely the most important ecosystem services provided by extensive green roofs (EGRs) that contribute to urban stormwater mitigation management. However, hydrological performance generation mechanisms of mature, well‐established EGRs in tropical regions remain poorly understood. This study evaluated rainfall retention, discharge times processes two neighbouring 20‐year‐old with different slopes (2° 14° for EGRns EGRws, respectively)...
