Climate‐driven resource availability drives medium‐ and broad‐scale temporal changes in owl–prey interactions over 24 years in a semi‐arid ecosystem

Ecography, EarlyView.
Predator–prey interactions are vital to ecosystem functioning but may be disrupted by climate change. We investigated a food‐web network involving three owl species over 24 years in a semi‐arid ecosystem at Bosque Fray Jorge National Park, Chile.

Estimation of Airborne Lidar-Derived Tropical Forest Canopy Height Using Landsat Time Series in Cambodia

Remote Sensing, 2014
In this study, we test and demonstrate the utility of disturbance and recovery information derived from annual Landsat time series to predict current forest vertical structure (as compared to the more common approaches, that consider a sample of airborne

Object-Based Greenhouse Mapping Using Very High Resolution Satellite Data and Landsat 8 Time Series [PDF]

, 2016
Greenhouse mapping through remote sensing has received extensive attention over the last decades. In this article, the innovative goal relies on mapping greenhouses through the combined use of very high resolution satellite data (WorldView-2) and Landsat

Butterfly abundances but not patch occupancy buffered by vegetation heterogeneity during climatic extremes

Ecography, EarlyView.
As extreme climatic events are becoming more frequent, we need to understand what mechanisms could buffer populations to ensure their persistence. Fragmented populations may be especially vulnerable, as exemplified by species with metapopulation dynamics whose persistence is determined by a precarious balance between frequent local extinctions and ...

Desertification mapping based ARIMA model and Landsat time series [PDF]

, 2020
Desertification models do not include analyses of rainfall, temporality, field visits and projection scenarios. The objective is to evaluate desertification under levels of vegetation, soil and albedo, construct forecast models and analyze its variability with time and rainfall. Landsat TM was used for NDVI, TGSI and albedo between 2000 and 2008 in dry

Remote Sensing for Irrigation Water Management—The State of the Art and Prospects for Near‐Future Operations

Irrigation and Drainage, EarlyView.
ABSTRACT A recent UN report describes many regions as facing ‘water bankruptcy,’ a condition in which available water resources can no longer meet existing demands. In practice, this means irrigation will likely bear the greatest burden of future water‐use reductions, a complicated and fraught decision to make given its critical role in food security ...

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.
