Review of the Salpausselkä ice‐marginal formations in Finland

Journal of Quaternary Science, EarlyView.
ABSTRACT Extensive Salpausselkä ice‐marginal formations were deposited in southern and eastern Finland during the Weichselian deglaciation. These comprise three major ridges (I, II, and III Salpausselkäs) and their eastern counterparts (Tuupovaara, Koitere, and Pielisjärvi), together forming laterally continuous ice‐marginal formations extending ...

Analysis of Landsat 8 detection of the interannual variability of grassland curing in Greater Melbourne, Australia

International Journal of Digital Earth, 2020
As one of the main components of Grassland Fire Danger Index, grassland curing degree provides crucial information for determining grassland fire danger. Accurate estimates of grassland curing are critical for determining grassland fire risk.

Late Quaternary lake filling and drying in northern Australia's largest freshwater lake

Journal of Quaternary Science, EarlyView.
ABSTRACT Lake Woods, Jurrkulu, is northern Australia's largest freshwater lake filled today in strong Indo–Australian summer monsoons (IASM) to maximum depths of ~5 m. On the western margins of the lake, two large arcuate ridges occur 20 to 40 m above the lake floor and inset within these are other mid‐elevation lake deposits, such as depositional ...

Landscape drivers of scaled quail occurrence across a broad spatiotemporal scale: implications for habitat management

The Journal of Wildlife Management, EarlyView.
Combining large‐scale avian surveys with remote sensing products revealed landscape variables that likely limit scaled quail occurrence at the ecoregion scale in Texas. Promoting management practices that address ecoregion‐specific limiting factors may be key to averting further declines.

Fusion of Landsat 8 OLI and Sentinel-2 MSI Data [PDF]

IEEE Transactions on Geoscience and Remote Sensing, 2017
Sentinel-2 is a wide-swath and fine spatial resolution satellite imaging mission designed for data continuity and enhancement of the Landsat and other missions. The Sentinel-2 data are freely available at the global scale, and have similar wavelengths and the same geographic coordinate system as the Landsat data, which provides an excellent opportunity

Cutting through the noise: What can habitat selection modeling teach us about caribou‐fire space use dynamics?

The Journal of Wildlife Management, EarlyView.
We synthesize the current knowledge regarding caribou habitat selection in relation to wildfires. Caribou responses to recent burns were generally weak and highly variable across subspecies or ecotypes, suggesting that post‐fire habitat selection is likely context‐dependent and the need for regionally adapted habitat management strategies.

Modeling effects of environmental conditions and hunter activity on Montezuma quail harvest in Arizona

The Journal of Wildlife Management, EarlyView.
Models of spatiotemporal variation in hunter harvest show that monsoon precipitation and changes in hunter behavior and composition are the primary drivers underlying variation in annual harvest of Montezuma quail. The demographic structure of the previous year's harvest was also strongly associated with the magnitude and rate of annual harvest ...
