The Accuracy of the Titan 1+ 10 Hz Global Positioning System for Measures of Time, Distance, and Top Speed Open
Introduction: Global Positioning System (GPS) technology provide quantifiable data concerning the number and types of movements athletes complete across training session and match player. The Titan 1+ is a novel GPS device that has not bee…

Combustion of Aboveground Wood from Live Trees in Megafires, CA, USA Open
Biomass combustion is a major biogeochemical process, but uncertain in magnitude. We examined multiple levels of organization (twigs, branches, trees, stands, and landscapes) in large, severe forest fires to see how combustion rates for li…

Plant community succession following ungulate exclusion in a temperate rainforest Open
Ecosystem structure and processes of coastal temperate rainforests of the Pacific Northwest are thought to be strongly influenced by herbivory primarily of Roosevelt elk ( Cervus elaphus roosevelti ) and secondarily of Columbian black‐tail…

Vegetation Succession in Elk Exclosures of Olympic National Park Open
Data describe changes in abundance of herbs, ferns, shrubs and trees inside and outside of elk exclosures over 36 years in Olympic National Park. Data were collected annually early in the time series and subsequently less frequently. Two e…

Dynamic prediction length for time series with sequence to sequence network Open
Recurrent neural networks and sequence to sequence models require a predetermined length for prediction output length. Our model addresses this by allowing the network to predict a variable length output in inference. A new loss function w…

Mortality in Forested Ecosystems: Suggested Conceptual Advances Open
Mortality of trees is an important ecological process altering forest structure and function as well as influencing forest management decisions. Recent observations suggest that the overall rate of tree mortality is increasing at local to …

Meeting GHG reduction targets requires accounting for all forest sector emissions Open
Atmospheric greenhouse gases (GHGs) must be reduced to avoid an unsustainable climate. Because carbon dioxide is removed from the atmosphere and sequestered in forests and wood products, mitigation strategies to sustain and increase forest…

Have product substitution carbon benefits been overestimated? A sensitivity analysis of key assumptions Open
Substitution of wood for more fossil carbon intensive building materials has been projected to result in major climate mitigation benefits often exceeding those of the forests themselves. A reexamination of the fundamental assumptions unde…

Nitrogen isotopes, carbon isotopes, and pyrolysis products in wood decay fungi, woody tissues, and cellulose from a long-term log decomposition experiment at H.J. Andrews Experimental Forest, Oregon, USA Open
We combined elemental, isotopic, and compositional patterns in wood, cellulose, and sporocarps to investigate functional and isotopic differences in six taxa of decay fungi during log decomposition. Fungal protein was 4-5‰ higher in δ15N a…

The Long-Term Effects of Wind Disturbance on a Sitka Spruce-Western Hemlock Forest Open
Wind is an important disturbance in many forested regions, but research has largely focused on immediate to short-term (<10 years) effects on species composition and structure of stands and landscapes. We used a set of ten, 0.4-ha plots es…

Estimating uncertainty in the volume and carbon storage of downed coarse woody debris Open
Downed coarse woody debris, also known as coarse woody detritus or downed dead wood, is challenging to estimate for many reasons, including irregular shapes, multiple stages of decay, and the difficulty of identifying species. In addition,…

Activation Ensembles for Deep Neural Networks Open
Many activation functions have been proposed in the past, but selecting an adequate one requires trial and error. We propose a new methodology of designing activation functions within a neural network at each layer. We call this technique …
