Restoration Ecology, EarlyView.Abstract Introduction Restoration outcomes in cold desert ecosystems like sagebrush steppe are affected by weather variability, particularly during the spring, a critical time period for seedling establishment. Seedling emergence phenology is also highly variable among species in these ecosystems.

Restoration Ecology, EarlyView.Abstract Introduction The Wetlands Reserve Easement (WRE) program accounts for the majority of private land afforestation in the Lower Mississippi Alluvial Valley (LMAV), but consistent ecological monitoring is not often feasible after restoration activities are complete.

Climate‐Smart Agricultural Assets and Household Coping Strategies in Times of Upheaval
Review of Development Economics, EarlyView.ABSTRACT Transferring agricultural assets can be welfare‐improving for smallholders. Can agricultural assets also improve smallholders' ability to cope with unprecedented exogenous shocks? We investigate this question using the case of subsidized solar‐powered irrigation pumps (SIP) during the time of upheaval (COVID‐19 pandemic) in Nepal.

Geology of a Part of the Panamint Range, California [PDF]
, 1932 The Panamint Range is a tilted fault-block, uplifted probably in Tertiary time and rejuvenated by very complex recent faulting on the west. This great block is approximately 100 miles long, but the reconnaissance geologic map covers only a tract in the ...

Sedimentology, EarlyView.ABSTRACT One of the largest wetlands on Earth, the Brazilian Pantanal contains roughly 10 000 natural lakes, about 1000 of which are hypersaline. In these environmentally stressful settings, animal life struggles to survive, while cyanobacteria form extensive mats.

Clastic sedimentary rocks of the Michipicoten Volcanic-sedimentary belt, Wawa, Ontario [PDF]
The Wawa area, part of the Michipicoten greenstone belt, contains rock assemblages representative of volcanic sedimentary accumulations elsewhere on the shield.

Sedimentology, EarlyView.ABSTRACT The c. 1 Ga Diabaig Formation of north‐west Scotland preserves diverse lacustrine and fluvial facies and abundant microbial and non‐microbial surficial sedimentary features. 172.6 m of section was logged across seven localities to assess the distribution of microbially induced sedimentary structures (MISS) relative to lithofacies, substrate ...

Quantitative analysis of channel characteristics of distributive fluvial systems
Sedimentology, EarlyView.ABSTRACT Distributive fluvial systems (DFSs) are characterised by a radial distributive channel pattern in planform and dominate modern‐day sedimentary basins. Where aggradation occurs, such as in sedimentary basins, there is increased preservation potential, and therefore, DFSs are hypothesised to constitute a significant portion of the continental ...

Determining the relationship between rock colour and the type of physical weathering on desert pavements in arid landscapes, Ras Al Khaimah, UAE [PDF]
, 2008 Despite opposition to the theory that diurnal heat fluxes within desert rocks cause enough internal stress to form cracks on clasts leading to the break down of the desert material, this study provides further evidence that this is a credible process in ...
