SNP genotyping in Pseudotsuga menziesii and Pinus radiata using targeted genotyping-by-sequencing (GBS): improved Bayesian SNP calling using a beta-binomial distribution and other optimized input parameters

BMC Genomics
Background Single-nucleotide polymorphism markers (SNPs) have important applications in gene conservation, breeding, and fundamental genetics research. Our long-term goal is to develop routine approaches for SNP genotyping in forest trees. Ideally, these

Succession influences wild bees in a temperate forest landscape: the value of early successional stages in naturally regenerated and planted forests. [PDF]

PLoS ONE, 2013
In many temperate terrestrial forest ecosystems, both natural human disturbances drive the reestablishment of forests. Succession in plant communities, in addition to reforestation following the creation of open sites through harvesting or natural ...

De novo synthesis of short‐chain aldehydes and hydrocarbons secreted by the brown marmorated stink bug Halyomorpha halys

FEBS Open Bio, EarlyView.
The brown marmorated stink bug, Halyomorpha halys, mainly secretes 4‐oxo‐(E)‐2‐hexenal, (E)‐2‐decenal, dodecane and tridecane, a mixture representative of that released by many heteropterans. We demonstrated that H. halys can synthesise these secretory components de novo using dietary glucose.

Landsat-Based Land Use Change Assessment in the Brazilian Atlantic Forest: Forest Transition and Sugarcane Expansion

Remote Sensing, 2018
In this study, we examine the hypothesis of a forest transition in an area of early expansion of the agricultural frontier over the Brazilian Atlantic Forest in the south-central part of the State of São Paulo.

Morphophysiological Evaluation of Schizolobium Parahyba Var. Amazonicum and Eucalyptus urograndis Growing in Different Levels of Shading

Floresta e Ambiente, 2022
This study aimed to identify the best shade level for the growth of Schizolobium parabyba var. amazonicum and Eucalyptus urograndis seedlings to obtain more resilient seedlings with higher quality. We used an entirely randomized design was used, in a 2 x

Neurochemical Endpoints to Inform Early‐Stage Trials of Spinocerebellar Ataxia 2 and 3 in a Multisite Setting

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Neurochemical levels measured by brain MR spectroscopy (MRS) have been proposed as endpoints for clinical trials in early‐stage spinocerebellar ataxia (SCA) trials. We tested their trial‐readiness by quantifying neurochemicals in three affected brain regions in early‐stage cohorts of SCA2 and SCA3, examining their reproducibility in ...

Coastal Protection by Planted Mangrove Forest during Typhoon Mangkhut

Journal of Marine Science and Engineering, 2022
Mangroves provide many ecosystem services, including coastal protection against storm surges and waves. As an adaptive method for coastal defense, mangroves were widely restored and planted in tropical and subtropical regions, such as the coastal regions

Machine Learning‐Supported Analysis for Predicting and Visualizing Nonlinear Relationships Between Material Properties in Electroplated Chromium Layers

Advanced Engineering Materials, EarlyView.
This study applies machine learning regression to predict chromium layer thickness in decorative trivalent chromium electroplating, using 441 experiments from laboratory‐scale (1L) and pilot‐scale (14L) setups. Tree‐based models, particularly CatBoost, outperformed linear regression by capturing nonlinear parameter interactions (R2$R^2$ up to 0.77 ...
