Holocene vegetation dynamics of Grande Terre (Kerguelen Islands) inferred from sedimentary ancient DNA

Journal of Quaternary Science, EarlyView.
ABSTRACT While the Antarctic region has experienced significant climatic changes over the Holocene, few high‐resolution records have examined their effects on the local biota. In order to understand past ecological shifts and forecast future changes, it is important to obtain high‐resolution palaeoecological records from this region.

Sourdough fermentation as a modulator of nutritional quality in cereal‐based baked products

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Sourdough fermentation, an ancient food bioprocessing technology, has attracted renewed attention for its positive impact on the nutritional profile and sensory attributes of leavened baked products. This process relies on the symbiotic activity between lactic acid bacteria and yeasts, which leads to acidification, proteolysis, enzyme ...

Validating antler‐ and movement‐based estimates of caribou reproduction using video camera collars Validation des estimations de la reproduction du caribou basées sur la rétention des bois et  sur le déplacement à l'aide de colliers‐caméras

The Journal of Wildlife Management, EarlyView.
We used GPS video camera collar data from barren‐ground caribou in the Porcupine and Western Arctic herds to validate antler‐ and movement‐based methods for estimating annual reproductive metrics. Antler retention was highly accurate for estimating parturition, but the movement methods we tested performed marginally for estimating parturition and ...

Is DNA metabarcoding an option for formaldehyde‐preserved zooplankton time series?

Limnology and Oceanography: Methods, EarlyView.
Abstract The recovery of amplifiable DNA from formaldehyde‐fixed (FF) zooplankton samples has long been considered problematic, but advances in degraded‐DNA retrieval have renewed interest in FF samples. To access the information stored in long‐term zooplankton time series, we evaluated methods for extracting amplifiable DNA from community samples ...

Artificial Intelligence‐Driven Natural Product Drug Discovery: From Computational Genome Mining to Clinical Translation

Medicinal Research Reviews, EarlyView.
ABSTRACT Natural products (NPs) have historically yielded numerous therapeutic agents, yet their integration into modern drug discovery has been constrained by chemical complexity, low abundance, laborious dereplication, and limited target annotation.

Entamoeba, giardia and toxoplasma: clones or cryptic species?

Parasitology Today, 1993
The availability of molecular markers has renewed interest in the taxonomy of parasitic protozoa at the subspecific and specific levels. Nevertheless, the conclusions reached are heavily dependent upon the way the data are analyzed. Some authors have emphasized the value of genetic distances to propose the creation o f new species, while others have ...

Data from: Cryptic diversity in a fig wasp community – morphologically differentiated species are sympatric but cryptic species are allopatric

, 2016
A key debate in ecology centres on the relative importance of niche and neutral processes in determining patterns of community assembly with particular focus on whether ecologically similar species with similar functional traits are able to coexist ...

Macro‐ and micromorphological insights into Iranian Onobrychis subgenus Onobrychis Miller (Fabaceae): exploring fruit traits for taxonomic clarity

Nordic Journal of Botany, EarlyView.
This study provides a comprehensive examination of fruit morphology and micromorphology characteristics of 28 populations of Onobrychis subgenus Onobrychis taxa from Iran, using both light and scanning electron microscopy. For each trait, 25 replicates were analyzed, encompassing a wide range of qualitative and quantitative traits.

Advances in research on autophagy in the maintenance of insect–microbe symbiosis

New Plant Protection, EarlyView.
Autophagy plays a dual regulatory role in insect–microbe symbiotic relationships. Beneficial symbiotic bacteria in insects participate in nutrient exchange via the TOR pathway, whereas pathogenic microbes induce immune defense through the AMPK pathway. Autophagy‐related genes regulate development and pathogen clearance during this process.
