Spatiotemporal Evolution of Hydroclimatic Variables in the Brazilian Semi‐Arid Region Through the Aridity Index and Susceptibility to Desertification

International Journal of Climatology, EarlyView.
Over the past 60 years, noticeable changes have been observed in the main hydroclimatological variables, driven by both natural and anthropogenic factors. In the context of climate change, such behaviour may adversely affect the state's economic activities, as well as increase the recurrence of extreme events in the region.

An Arctic sea ice concentration data record on a 6.25 km polar stereographic grid from 3 years of Landsat-8 imagery [PDF]

Earth System Science Data
The decline in Arctic sea ice in the global warming era has received much attention as a contributing factor to the changes in the weather and climate in the Arctic and beyond. The coverage of Arctic sea ice (i.e.

Landsat 8 Virtual Orange Band for Mapping Cyanobacterial Blooms

Remote Sensing, 2020
The Landsat 8 Operational Land Imager (OLI) has a panchromatic band (503−676 nm) that can be used to derive a novel virtual orange band (590−635 nm) by using the multispectral green band and red band components.

A Quantitative Assessment of Forest Cover Change in the Moulouya River Watershed (Morocco) by the Integration of a Subpixel-Based and Object-Based Analysis of Landsat Data [PDF]

, 2016
A quantitative assessment of forest cover change in the Moulouya River watershed (Morocco) was carried out by means of an innovative approach from atmospherically corrected reflectance Landsat images corresponding to 1984 (Landsat 5 Thematic Mapper) and ...

Moose indifferent to canopy loss from forest disturbance by bark beetles

The Journal of Wildlife Management, EarlyView.
Moose showed strikingly similar patterns of habitat selection before and after widespread forest disturbance following an infestation of bark beetles. Our findings indicate that beetle‐kill does not appreciably alter habitat quality for moose and highlight the importance of riparian areas in sustaining moose as they contend with changing forests ...

A comparative study of ALOS-2 PALSAR and landsat-8 imagery for land cover classification using maximum likelihood classifier

Egyptian Journal of Remote Sensing and Space Sciences, 2018
This study examines ALOS-2 PALSAR L-band dual-polarization (HH and HV) SAR data and Landsat-8 optical imagery for land cover classification. The SAR data has been preprocessed first, which included radiometric calibration, geocoding, and speckle ...

Nutritional and reproductive dynamics of moose near their southern range limit

The Journal of Wildlife Management, EarlyView.
Though southern moose (Alces alces) had relatively low seasonal fluctuations in body fat, their condition was positively associated with pregnancy and adult survival but did not influence recruitment of young. We demonstrated clear signs of nutritional limitation and unexpected patterns of reproductive performance that may be unique to moose living at ...

Desertification Risk: Bibliometric Analysis and Future Research Directions

Land Degradation &Development, EarlyView.
ABSTRACT Desertification, driven by climatic and anthropogenic factors, is one of the most pressing global environmental challenges, causing significant economic, ecological, and social consequences. A bibliometric analysis was performed to identify research trends and gaps in the desertification risk topic.

Coupling Water Purification and Carbon Sequestration at Various Spatial Scales From Supply and Demand Perspective

Land Degradation &Development, EarlyView.
ABSTRACT Balancing ecosystem‐service supply and demand is central to understanding both the natural and social dimensions of ecosystem services and to enhancing human well‐beings. Concurrently, collaborative efforts are underway to improve multiple ecosystem services, including the promotion of carbon neutrality and water purification (WP) within basin
