Forest decline first came to public attention when the dominant silvicultural tree of Germany showed damage on a large geographic scale. Damaged Norway spruce, Picea abies (L.) Karts., displayed symptoms which could not be explained by known pathogens or other factors. In the Fichtelgebirge (...

Forestry is the province of variability. From a spatial point of view this variability ranges from within-tree variation (e.g. modeling wood properties) to billions of trees growing in millions of hectares (e.g. forest inventory). From a temporal point of view we can deal with daily variati...

An introduction to the aquatic insects of North America Rock phosphate, basic slag, and superphosphate supplying 330, 120, and 120 pounds of P2O5 per acre, respectively, were applied to replicated plots on Bernard clay loam in the fall of 1949 to determine their effects upon the production an...
Ponderosa pine seeds used in the “broadcast seeding” plots originated from the Roosevelt National Forest in north-central Colorado. Seeds were kept in cold storage and had 70% germination viability. In October 2015, seeds were dispersed using a hand-held broadcast seeder at 158 g per subplot ...
1. Introduction In this post we discuss the H2O machine learning platform. We talk about what H2O is, and how to get started with it, using R - we create a Random Forest which we use to classify the Iris Dataset. 2. What is H2O? The definition foun...
11 From you, O Nineveh,[aw] one has marched forth who plots evil against the Lord,a wicked military strategist.[ax] Oracle of Deliverance to Judah 12 This is what the Lord says:[ay] “Even though[az] they are powerful[ba]—and what is more,[bb] even though their army is numerous...
In these plots, a point is generated for each taxon within its corresponding sample that is proportional in size to its relative abundance. Potential indicator taxa of the different core sections and modern assemblages were identified using the Indicator Value (IndVal) (Dufrene and Legendre 1997) ...
This post is a gentle introduction to it, hope you enjoy it! Find me on Twitter and Linkedin. Clone this github repository to reproduce the plots. Introduction Complex predictive models are not easy to interpret. By complex I mean: random forest, xgboost, deep learning, etc. In other words...
