Chemistry &Biodiversity, EarlyView.ABSTRACT Yeasts belonging to the genus Rhodotorula are capable of synthesizing carotenoids, such as β‐carotene, γ‐carotene, torulene, torularodine, and astaxanthin. These carotenoids have been shown to offer health benefits to humans, such as immune system strengthening and a reduced risk of chronic degenerative diseases.

Successful modeling of the environmental changes' influence on forests' vegetation over North Eurasia [PDF]
arXiv, 2010 Modeling of forests' vegetation in North Eurasia has been performed for 1982-2006 on the basis of remote sensing data. Four meteorological parameters and one parameter, characterizing geomagnetic field disturbance level, were used for this aim. It was found out that revealed formula is adequate both for coniferous evergreen and coniferous deciduous ...

Understanding the drivers of sustainable land expansion using a patch-generating land use simulation (PLUS) model: A case study in Wuhan, China [PDF]
arXiv, 2020 Cellular Automata (CA) are widely used to model the dynamics within complex land use and land cover (LULC) systems. Past CA model research has focused on improving the technical modeling procedures, and only a few studies have sought to improve our understanding of the nonlinear relationships that underlie LULC change.

Scalogram habitat measures as predictors of bird abundance
Ecography, EarlyView.Birds select habitat characteristics, such as variability in habitat structure, across multiple spatial scales (grain and extent). Measuring habitat variability at multiple scales can better capture factors that influence avifauna communities than focusing on one scale only. One valuable tool in assessing habitat heterogeneity is the cumulative dynamic

A Spatial Concordance Correlation Coefficient with an Application to Image Analysis [PDF]
arXiv, 2019 In this work we define a spatial concordance coefficient for second-order stationary processes. This problem has been widely addressed in a non-spatial context, but here we consider a coefficient that for a fixed spatial lag allows one to compare two spatial sequences along a 45-degree line.

, 2014 Plant phenology regulates ecosystem services at local and global scales and is a sensitive indicator of global change. Estimates of phenophase transition dates, such as the start of spring or end of fall, can be derived from sensor- based time series ...

Trade‐offs among restored ecosystem functions are context‐dependent in Mediterranean‐type regions
Ecography, EarlyView.Global biodiversity hotspots, including Mediterranean‐type ecosystems worldwide, are highly threatened by global change that alters biodiversity, ecosystem functions, and services. Some restoration activities enhance ecosystem functions by reintroducing plant species based on known relationships between plant traits and ecosystem processes.

An empirical model for the vegetation screening effect in the remote sensing monitoring [PDF]
arXiv, 2017 A layer of vegetation over the soil surface absorbs microwave radiation emitted from the soil and some objects located under the vegetation canopy. This paper investigates the microwave propagation process within the vegetation layer and evaluate the attenuation coefficients. For this purpose, laboratory experimental test bench is synthesized.

Analyses of the Erosive Effect of Dietary Substances and Medications on Deciduous Teeth
PLoS ONE, 2015 This study aimed at analysing the erosive potential of 30 substances (drinks, candies, and medicaments) on deciduous enamel, and analyse the associated chemical factors with enamel dissolution.
