Estimating crippling loss from hunting with multistate models: a case study on northern bobwhites
Wildlife Biology, EarlyView.Hunting as a recreational pursuit provides an important ecosystem service worldwide. Harvest management plays a vital role in regulating wildlife take to ensure long‐term population sustainability and meet value‐based objectives (e.g. hunter satisfaction). However, managers rarely have complete control or observability of harvest mortality.

Costs and efficiency of timber harvesting by NIAB 5–15 processor mounted on a farm tractor
Croatian Journal of Forest Engineering, 2007 The present research deals with costs and economic effectiveness of timber harvesting technology with the use of the NIAB 5–15 processor mounted on a farm tractor, which method is used in Poland. Measurements were conducted in pine, fir and spruce stands,

Computer Vision for Timber Harvesting [PDF]
, 2009 The goal of this thesis is to investigate computer vision methods for timber harvesting operations. The background for developing computer vision for timber harvesting is to document origin of timber and to collect qualitative and quantitative parameters

Wildlife Society Bulletin, EarlyView.Abstract Limited engagement between Black Americans and wildlife is often treated as cultural disinterest rather than the outcome of historical exclusion, racialized trauma, or persistent structural barriers. This perspective obscures the long‐standing relationships Black communities have had with land, agriculture, and conservation, and constrains ...

CIRI LIMBAH PEMANENAN KAYU DI HUTAN RAWA GAMBUT TROPIKA
Jurnal Ilmu Pertanian Indonesia, 2013 Effectiveness of timber harvesting in peat swamp forest is low. It is indicated by highly logging waste caused by timber harvesting operation. Thus, logging waste should be studied to describe characteristic and volume of logging waste in locations of ...

Comparison of data handling techniques for modeling bat acoustic activity
Wildlife Society Bulletin, EarlyView.We deployed 169 acoustic recording units (A) across the Raystown Lake Project, Huntingdon County, Pennsylvania, USA (B). Echolocation recordings were used to evaluate alternative acoustic data handling methods and their effects on bat acoustic activity model predictions.

Forestry Economics: Principles and Practice [PDF]
This review discusses bioeconomic models of the forest and uses them to explore policy options for forest management. The main type of bioeconomic model used is based on a biomass model of the growth of the forest, similar to the biomass model widely ...

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Home‐Field Advantage (HFA) theory—positing that litter decomposes faster at its site of origin—allows us to disentangle the respective influences of litter quality, soil biota composition, and microclimate on shifts in litter decomposition following land use conversion.

Apex predators exploit advantageous snow conditions across hunting modes
Journal of Animal Ecology, EarlyView.Advantageous snow conditions—in terms of snow depth and density—are among the most important features of the winter landscape for two apex predators, regardless of hunting strategy. In a warming climate, the knock‐on effects of a diminishing snowpack may reduce the hunting success of multiple large carnivore species.
