Microclimf: Fast modelling of microclimate across real landscapes in R

Methods in Ecology and Evolution, EarlyView.
Abstract Many ecological studies require climate data, but readily available datasets are poor surrogates for the conditions that organisms experience in nature. Understanding the climatic conditions experienced by organisms requires modelling microclimate rather than relying on coarse, station‐based climate data.

GIS and field data-based modelling of snow water equivalent in shrub tundra

Fennia: International Journal of Geography, 2015
An approach for snow water equivalent (SWE) modelling in tundra environments has been developed for the test area on the Yamal peninsula. Detailed mapping of snow cover is very important for tundra areas under continuous permafrost conditions, because ...

Integrated Species Distribution Model Using Historical Data Shows Decline in a Common Semi‐Aquatic Mammal

Animal Conservation, EarlyView.
A diagram of the integrated species distribution model of river otter intensity of use. Three types of data (latrine detections, roadkill detections, and detection/nondetection surveys) are linked by different observation processes to the same underlying intensity of use.

What controls forest litter decomposition? A coordinated distributed teabag experiment across ten mountains

Ecography, EarlyView.
Litter decomposition in mountainous forest ecosystems is an essential process that affects carbon and nutrient cycling. However, the contribution of litter decomposition to terrestrial ecosystems is difficult to estimate accurately because of the limited comparability of different studies and limited data on local microclimatic and non‐climatic factors.

Towards Improved Snow Water Equivalent Estimation via GRACE Assimilation [PDF]

Passive microwave (e.g. AMSR-E) and visible spectrum (e.g. MODIS) measurements of snow states have been used in conjunction with land surface models to better characterize snow pack states, most notably snow water equivalent (SWE). However, both types of

Extreme weather and economic crisis in the 1430s in England, and the implications for tenurial change

The Economic History Review, EarlyView.
Abstract The 1430s were characterized by extreme weather conditions, food and fodder shortages, and high mortalities among animals and humans, although the severity of events and their consequences in England have received limited attention. The economic downturn and the depressed customary land market in this decade marked the beginning of the Great ...

High resolution spatial variability in spring snowmelt for an Arctic shrub-tundra watershed [PDF]

, 2019
Arctic tundra environments are characterized by spatially heterogeneous end-of-winter snow cover because of high winds that erode, transport and deposit snow over the winter.
