Using information theory to select spatial scales for species–habitat responses with camera traps
Abstract Widespread anthropogenic landscape change, particularly from energy development, has fundamentally reshaped ecosystems, and understanding species responses remains a central ecological challenge. Remote camera traps are widely used to estimate mammal abundance and distribution, but inferring species–habitat relationships from these data is ...

We found that Western Fence Lizards experience higher detectability in burned areas but do not consistently darken or adjust perch use to enhance background matching, despite showing improved camouflage on darker substrates. These results suggest that lizards may face behavioral trade‐offs in post‐fire landscapes that could influence success.

We integrated ecological niche modeling (MaxEnt) with a remote sensing–driven machine‐learning productivity model (BRT), using 3139 Chinese fir occurrences, MODIS‐derived NPP, and 37 climate–soil predictors to project future suitability and productivity under a 13‐GCM CMIP6 ensemble (SSP245/SSP585).

Assessment of Nontarget Small Mammal Occupancy Using Broadly Designed Camera Arrays
Camera traps are a mainstay method in ecological research and monitoring, often focusing on a single species; however, many nontarget species are captured as well. We aimed to assess the distributions and trends in the occurrence of nontarget species captured by an existing camera trap study initially designed to monitor mesocarnivores in Rhode Island,

Vegetation and Topographic Controls on Post‐Fire Snowpack: Evidence From the 2021 Caldor Fire
ABSTRACT The increase in wildland fires in recent decades due to long‐term fire suppression policies and increasingly favourable climate factors has also increased the elevation range of wildland fires. In the mountainous western United States, this has led to an increasing influence of fire on landscape‐level vegetation patterns in snow‐dominated ...

Using LiDAR to quantify, map, and conserve late‐successional and old‐growth forest in Maine, USA
Abstract The world continues to lose late‐successional and old‐growth (LSOG) forest as the human population and demand for wood fiber grow. However, older forest age classes provide structural and compositional characteristics important to biodiversity that are often not present in forests managed for timber.

ABSTRACT Deforestation and its social impacts are an enduring challenge in agrarian frontiers, especially in the tropics. Fueled by global demand for commodities, this process is mediated by ideas, concepts, meanings, and policies that uphold socioenvironmental degradation. A key and understudied—arena in which this mediation occurs is the sub‐national

Is timber harvesting related to deforestation? On the unsustainable nature of timber harvesting
Deforestation is a major environmental issue, while demand for timber products increases rapidly in the developing world. One can thus wonder whether forest harvesting is sustainable worldwide, or if demand for timber products is fulfilled with the products from deforestation. Our panel data analysis shows that countries where timber harvesting is more

Governance and Timber Harvests
Environmental and Resource Economics, 2010Resource economics theory implies that risks associated with weak governance have an ambiguous impact on extraction, with the net impact depending on the relative strengths of depletion and investment effects. Previous empirical studies have found that improved governance tends to reduce deforestation but to raise oil production.

The use of a harvester head, processor head or merchandiser to deploy or place probes into a standing tree, felled stem or trunk, log, cant or the like whereby a time of flight of a stress or acoustic wave can be measured for the purpose of comparing a relationship to a threshold for the purpose of attributing a characteristic to be harvested ...
