Diatom-Inferred Changes in Effective Moisture From Gall Lake, Northwestern, Ontario, Over the Past Two Millennia
The boreal forest of Canada extends across 58% of Canada’s land area providing a large range of ecosystem services including flood control, water filtration, and carbon storage. Despite conservation efforts to protect this ecosystem, the boreal region is still under stress from global stressors …

Holocene variations in summer temperature and effective moisture: Understanding the causes of vegetational dynamics in Alaska
… to test the role of orbital forcing and moisture balance on interior Alaskan vegetation assemblages. The results presented here provide some of the first high-resolution, vegetation-independent climate records from Alaska that span the entire Holocene and highlight heterogeneous climatic …

Assessing changes in pollen assemblage and charcoal accumulation during known changes in climate from c. 5,400 to 3,300 Years Before Present at the forest-prairie ecotone in Alberta, Canada
… To assess the ecotonal response to changes in effective moisture, as inferred by diatom-inferred salinity, temporal variations in pollen and charcoal preserved in a sediment core from Chauvin Lake were analyzed over several diatom-inferred moisture-cycles from c. 5,400 to 3,300 YBP. Changes in …

Holocene climate change and peatland dynamics in southern Sweden based on tree-ring analysis of subfossil wood from peat deposits
… bog-tree growth variability is controlled by effective moisture was performed by comparing RW data with tree-ring carbon (δ13C) and oxygen (δ18O) isotope records. Variations in the isotopic records confirm that growth depressions coincided with moister atmospheric conditions and reveal a lag …

Species response to shifting and variable climates
… of selective pressure for comparatively lower effective moisture than surrounding regions that also harbored black spruce during the last glacial-interglacial cycle. The genomic imprint detected in this study, consistent with ongoing adaptation to contrasted modern-day selective pressures, …

Reconstructing climate variability on the Tibetan Plateau : comparing aquatic and terrestrial signals
Spatial and temporal temperature and moisture patterns across the Tibetan Plateau are very complex. The onset and magnitude of the Holocene climate optimum in the Asian monsoon realm, in particular, is a subject of considerable debate as this time period is often used as an analogue for recent …

Hydrology across scales : sensitivity of East African lakes to climate changes
… explores the effect of the morphology and the effective moisture of a lake catchment. The availability of digital elevation models (DEM) and gridded climate data sets facilitates the comparison of the morphological and hydroclimatic conditions of rift lakes. I used the hypsometric integral (HI) …

Use of ultrasonication, thermogravimetric analysis and newly developed hot-air drying platform for evaluation and optimization of drying processes of agricultural materials
… to 22%, yielding products with lower equilibrium moisture content (which can improve shelf-life), and increasing the hydration rate and equilibrium moisture content of hydrated grains. The second study was undertaken to examine changes in the drying and drying rate curves, moisture diffusivity, …
