Assessing and mitigating systematic errors in forest attribute maps utilizing harvester and airborne laser scanning data [PDF]
arXiv, 2022 Cut-to-length harvesters collect useful information for modeling relationships between forest attributes and airborne laser scanning (ALS) data. However, harvesters operate in mature forests, which may introduce selection biases that can result in systematic errors in harvester data-based forest attribute maps.

Shaping the human face: Periosteal bone modeling across ontogeny
The Anatomical Record, EarlyView.Abstract Facial morphology is a defining aspect of Homo sapiens that distinguishes our species from fossil ancestors and plays a central role in estimating age, sex, and ancestry in both past and present populations. Understanding how the face develops during postnatal ontogeny is essential for interpreting adult facial variation.

Frontiers in Forests and Global Change, 2020 Wood density is strongly related to key aspects of tree physiological performance. While many studies have examined wood density in different parts of trees, for a variety of reasons, there are very few studies that have compared within-tree density ...

Putative biotic drivers of plant phenology: With special reference to pathogens and deciduousness
Ecology and Evolution, 2022 Plant phenology is not only manifested in the seasonal timing of vegetative and reproductive processes but also has ontogenetic aspects. The adaptive basis of seasonal phenology has been considered mainly in terms of climatic drivers.

Deep learning for conifer/deciduous classification of airborne LiDAR 3D point clouds representing individual trees [PDF]
arXiv, 2018 The purpose of this study was to investigate the use of deep learning for coniferous/deciduous classification of individual trees from airborne LiDAR data. To enable efficient processing by a deep convolutional neural network (CNN), we designed two discrete representations using leaf-off and leaf-on LiDAR data: a digital surface model with four ...

Re-imagining the Future of Forest Management -- An Age-Dependent Approach towards Harvesting [PDF]
arXiv, 2023 Facing the drastic climate changes, current strategies for enhancing carbon dioxide stocks need to be thoroughly honed. To address the problem, we first built a carbon sequestration growth model driven by growth rate dependency (GRDM). We abstracted the carbon cycling system into the process of photosynthesis, the humidity fluctuation, and the original

Discrimination of Deciduous Tree Species from Time Series of Unmanned Aerial System Imagery
PLoS ONE, 2015 Technology advances can revolutionize Precision Forestry by providing accurate and fine forest information at tree level. This paper addresses the question of how and particularly when Unmanned Aerial System (UAS) should be used in order to efficiently ...

Sharpening our understanding of saber‐tooth biomechanics
The Anatomical Record, EarlyView.Abstract Saber‐teeth are a striking example of convergent evolution in vertebrate predators, having evolved multiple times in mammals and their early ancestors. While there is broad consensus that saber‐toothed taxa employed a distinct biting strategy compared to conical‐toothed carnivores, like the lion, the precise mechanics and variability of this ...

Commentary: What's so interesting about sabertooths?
The Anatomical Record, EarlyView.Abstract Sabertooth creatures are fascinating to the public and to scientists. This Special Issue on The Anatomy of Sabertooths starts with a discussion of what exactly a sabertooth is, continues with a couple of papers about other animals with extraordinarily long teeth, and then delves into analyses of fossil sabertoothed taxa—some of which are not ...
