Abstract:
... Fire regimes have changed due to environmental and socioeconomic factors which have led to an increase in the number, frequency, intensity, extension, and severity of fire events. On this context, postfire management is crucial for preserving forest ecosystems’ functions and biodiversity, and returning them to prefire levels (both in the short- and long-term) after wildfires. Currently, there is a ...

Abstract:
... Exploring how watershed partition influences hillslope and channel sediment in the Soil & Water Assessment Tool is important to identify the partition threshold and improve the model application in soil erosion evaluation. However, the influences on the channel phase, and the partition threshold for the entire watershed sediment process have not yet been well addressed. The Xixi basin located in s ...

Abstract:
... The taxonomy of Cinclidium, with only four species recognized, has been remarkably stable compared to most other genera in the Mniaceae. Two bisexual diploids (C. stygium and C. subrotundum) with n = 14 and two unisexual haploids (C. arcticum and C. latifolium) with n = 7 have been accepted since 1877, when C. latifolium was the last of these to be described. In the course of our inquiries into th ...

Abstract:
... Landslides are common disturbances in forests around the world, and a major threat to human life and property. Landslides are likely to become more common in many areas as storms intensify. Forest vegetation can improve hillslope stability via long, deep rooting across and through failure planes. In the U.S. Rocky Mountains, landslides are infrequent but widespread when they do occur. They are als ...

Abstract:
... Uphill-facing scarps are typical surface expressions of deep-seated gravitational slope deformations and are commonly created by flexural toppling. However, their evolution mechanisms are not well-understood partly because of the difficult in observing their internal structures. This study therefore performed high-resolution geomorphic analyses and thorough geological mapping in a slate-rich area ...

However, despite this ample literature, clear guidelines about the effectiveness and feasibility of the different restoration techniques in environmental contexts showing variable responses still lack. Furthermore, postfire hydrolog ...

There is a growing recognition that examining patterns of ecological communities and their underlying determinants is not only feasible based on taxonomic data, but also functional and phylogenetic approaches. This is because these additional facets can enhance the understanding of the relative contribution of multiple processes in shaping biodiversity. However, few studies have focused on multifa ...

Abstract:
... Although numerical methods based on strength reduction are becoming popular in slope stability analysis, they fail to provide a distinct critical slip surface and only provide a shear band. The widely used visualization techniques for defining the critical slip surface are susceptible to subjective judgment and are inefficient for batch analysis and three-dimensional analysis. When a slope fails, ...
