The Hidden Harvest: Harnessing Colorado's Geodiversity and Environmental Heterogeneity for Sustainable Agritourism

open access: yesSustainable Development, EarlyView.
ABSTRACT Colorado's geologic, pedologic, topographic, hydrological, and climatic contrasts create strong but under‐synthesized opportunities for sustainable agritourism. This review investigates how geodiversity, and the broader environmental heterogeneity within which it operates, can be used to diversify farm income, strengthen place‐based visitor ...

Modelling the hydrological process of the karst spring using a revised Vensim model

open access: yes地质科技通报, 2022
The conventional Vensim model uses two parallel reservoirs to simulate the slow and fast flows in karst systems, which can hardly simulate the existing nonlinear hydrological process.

Varying hydraulic strategies within leaves, stems and roots of coexisting desert shrubs

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Effective and continuous root‐to‐leaf hydraulic transport is crucial for plant survival and growth during drought. However, the capacity to resist hydraulic dysfunction remains understudied in leaves and roots, especially for desert shrubs.

Classification and characteristics of karst reservoirs in China and related theories

open access: yesPetroleum Exploration and Development, 2009
Karst reservoirs are distributed widely in China, for which integrated geological, logging, testing, and seismic identification marks can be made and their ages can be determined using unconformity surfaces, the lithologic features, and paleobiology of ...
