Larval mortality of leafcutting bee, Megachile pacifica (Panzer)
(= rotundata (F.)), is high, usually exceeding 50%. Parasites and
predators are not a limiting factor in the survival of the progeny.
The disease chalk brood has been an important mortality factor since
1974. Inadequate food supply, pollen and nectar, may affect...
Interactions and feedbacks among climate change effects and continued human impacts will exacerbate impacts to water resources in complex ways. An urgent imperative of the hydrologic community is to understand the response of hydrologic systems to these perturbations, thus contributing to long-term sustainability of water resources in an uncertain future....
Climate change impacts everyone’s food and water security. Increasing global temperatures accelerate the hydrologic cycle and consequently impact the water resources for billions of people worldwide. Countless models have been developed to represent various components of the hydrologic cycle at various spatial and temporal scales. These are often validated against...
The development of ecohydrological frameworks and theories under the ongoing global climate crisis depends on the development of new and advanced ecohydrological measurements. Currently, numerous of datasets have been collected at plot and ecosystem levels to understand the complex interactions of along the soil, plant, and atmosphere continuum. The development...
The knowledge about the intensive agricultural irrigation is very limited, but the use of irrigation is rapidly increasing. As an outcome, the sympathetic ecosystem is accepting modern irrigation that will play an essential function in the present and future for agricultural products. My dissertation will display the modification for investigation...
Transpiration (T), or the evaporation of water through plant stomata, plays a critical role in climate and biophysical processes at the earth’s surface. While T makes up a majority of the terrestrial evapotranspiration (ET) flux on a global scale, the partitioning of ET is variable and remains elusive. Because photosynthetic...

Transpiration (T), or the evaporation of water through plant stomata
Knowledge of the mean recharge elevation (MRE) of water resources is
important for informing conservation and protection practices where water security is threatened by population growth, urban expansion, and land and climate changes. In this study a Bayesian approach was developed and applied to determine the MRE of 682 surface...
Satellite Based evapotranspiration (ET) models have become a dominant means to estimate large-scale surface fluxes of water. Global and regional ET estimates are important parameters in many climate forecasts and hydrologic models. However, large scale partitioning of ET into soil evaporation, transpiration, and canopy interceptions remains largely unknown and modeled...
