Climate‐modulated accumulation and erosion of sediments in the Rodderberg crater basin for the last 439 ka (East Eifel Volcanic Field, Germany)

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Glacial/interglacial climate cycles since marine isotope stage (MIS) 12 influenced the discontinuous and 73 m‐long sediment record from the volcanic crater of Rodderberg in the East Eifel Volcanic Field, Germany. High‐resolution grain size and geochemical data have been valued by numerical dating techniques (radiocarbon and luminescence dating,

L-asparaginase activity in bacteria from estuarine sediments and mollusc

open access: yes, 1991
36-39L-asparaginase activity of bacteria, isolated from estuarine sediments and mollusc Villorita cyprinoids, was studied in 642 strains. Based on the activity, these strains were divided into 5 groups.

Macronutrient and micronutrient profiles of meat types: insights into human health and diet

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract Despite considerable advances in global health and nutrition, emerging challenges such as population growth, climate change, and limited natural resources continue to threaten food security. Meat remains an essential component of the human diet, supplying high‐quality proteins, essential amino acids, lipids, vitamins, and minerals necessary ...

Extraction‐dependent changes in immunoglobulin E binding profiles of processed lesser mealworm (Alphitobius diaperinus) proteins

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Alphitobius diaperinus, the lesser mealworm, is an edible insect considered safe for human consumption; however, its proteins show documented cross‐reactivity with crustacean and house dust mite (HDM) allergens, raising potential concerns for allergic populations.

Method‐dependent differences in zooplankton abundance and size metrics: Microscopy vs. ZooScan

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Image‐based approaches such as ZooScan are increasingly used for high‐throughput zooplankton monitoring. However, quantitative evaluations of methodological differences relative to conventional microscopy remain limited. In this study, zooplankton abundance and size‐based metrics obtained from microscopy and ZooScan image analysis were ...

Variation in nuclear genome size in a freshwater snail model system featuring a recent whole-genome duplication

open access: yesRoyal Society Open Science
Conspecifics often share—or are assumed to share—nuclear genome characteristics like nucleotide composition and genome size. These fundamental aspects of the nuclear genome can themselves be the object of natural selection. We here provide the first high-
