Vegetation and environmental dynamics in the central part of the Kola Peninsula during the past 13.3 ka as reflected by ancient plant DNA on sediments from Lake Imandra

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT The first high‐resolution reconstruction of the vegetation and environmental changes during the last ca 13 300 cal a BP in the central part of the Kola Peninsula (NW Russia) was reconstructed based on sedimentary ancient DNA (sedaDNA) metabarcoding on sediment core Co1410 from Lake Imandra.

Regional onset of Holocene drying period estimated from sand deposit analyses in Kharga Oasis, Western Desert, Egypt

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Desertification in North Africa has progressed rapidly over the past 6000 years. The occupation of Egypt by the Achaemenid Persians and Romans occurred even in hyperarid climates. Understanding the process of environmental changes on a regional scale may improve knowledge of how people developed technologies and adapted to the natural ...

How Effective Are Cleaners With “Effective Microorganisms”?

open access: yesJournal of Surfactants and Detergents, EarlyView.
ABSTRACT Microbial‐based cleaning products containing active microorganisms, such as Bacillus spores and “Effective Microorganisms” (EM)—a blend of lactic acid bacteria, photosynthetic bacteria, and yeast—are marketed for their potential to clean and displace pathogens. This study evaluated the efficacy of EM‐based cleaners by analyzing their microbial

Daphnia‐associated bacterial communities correlate with diet quantity, environmental conditions, and epidemic size across natural outbreaks

open access: yesLimnology and Oceanography, EarlyView.
Abstract Zooplankton‐associated microbiomes play an important role for host health, and contribute to ecosystem processes such as nutrient cycling. Yet, few studies have assessed how environmental gradients and biotic interactions, including parasitism and diet, may shape the microbiome composition of wild zooplankton. Here, we analyzed the microbiomes
