Gene and Genome Duplication in Spiders

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In chelicerates whole genome duplications (WGDs) were identified in distinct groups. While there is evidence that Xiphosurans/horseshoe crabs had three rounds of WGD and arachnopulmonates (e.g. spiders and scorpions) had one WGD, in many other arachnid groups no WGD was identified.

High Temperatures and Bacillus Inoculation Affect the Diversity of Bradyrhizobia in Cowpea Root Nodules

Journal of Basic Microbiology, EarlyView.
ABSTRACT Future climatic scenario predictions indicate a substantial temperature increase, reducing crop production worldwide and demanding the development of adaptations in agriculture. This study aimed to assess the impact of high temperatures and amendments with Bacillus on nodulating bradyrhizobia.

Concurrent DNA meta‐barcoding and plankton imaging reveal novel parasitic infection and competition in a diatom

Limnology and Oceanography, EarlyView.
Abstract Little is known about diatom parasitism in marine systems. Guinardia delicatula, a biomass‐dominant diatom on the Northeast US Shelf (NES), is regularly parasitized by the protistan nanoflagellate, Cryothecomonas aestivalis in this region. While G.

Seasonal and spatial transitions in phytoplankton assemblages spanning estuarine to open ocean waters of the tropical Pacific

Limnology and Oceanography, EarlyView.
Abstract Islands in the tropical Pacific supply elevated nutrients to nearshore waters that enhance phytoplankton biomass and create hotspots of productivity in otherwise nutrient‐poor oceans. Despite the importance of these hotspots in supporting nearshore food webs, the spatial and temporal variability of phytoplankton enhancement and changes in the ...

Heterotrophy of particulate organic matter subsidies contributes to divergent bleaching responses in tropical Scleractinian corals

Limnology and Oceanography, EarlyView.
Abstract Heterotrophic feeding on plankton and particulate organic matter (POM) by tropical Scleractinian corals is known to aid in the resistance and recovery from thermally induced bleaching. However, the relative importance of heterotrophy in promoting bleaching resistance and recovery is likely to vary based on ecological context and the severity ...

Impact of glacial cycles and ocean currents on radiation events in the Japanese turban snail Lunella coreensis

Limnology and Oceanography Letters, EarlyView.
Abstract The Japanese turban snail Lunella coreensis is sensitive to ocean currents due to its short pelagic larval stage and moderate dispersal ability, making it an ideal model for studying genetic diversity shaped by paleoclimatic shifts. In this study, we analyzed the mitochondrial genes COI and 12S of museum samples collected from various coasts ...

Concurrent global change and marine heatwaves disturb phototrophic more than heterotrophic protist diversity

Limnology and Oceanography Letters, EarlyView.
Abstract Anthropogenic pressures like ocean warming, acidification, rising N : P ratios, and marine heatwaves (MHWs) are affecting eukaryotic plankton diversity, though their combined impacts are rarely studied. To address this, we conducted a mesocosm experiment on a North Sea plankton community, testing the influence of a MHW under ambient and future

Using the diel cycle of ocean microbes to better understand their biogeochemical functions

Limnology and Oceanography Letters, EarlyView.
Abstract The daily cycle of solar radiation has a profound influence in structuring the physiology of microbes in the euphotic zone and subsequently setting the degree of coupling across trophic levels within ocean ecosystems. There has been an upsurge of interest in the biological role of the diel cycle and the ability to probe it using molecular ...

The Antiviral Activity of Polyphenols

Molecular Nutrition &Food Research, EarlyView.
Polyphenols demonstrate remarkable antiviral properties by effectively disrupting multiple biochemical processes essential for viral replication. ABSTRACT Polyphenols are secondary metabolites produced by a large variety of plants. These compounds that comprise the class of phenolic acids, stilbenes, lignans, coumarins, flavonoids, and tannins have a ...

Comparative LC‐MS Proteomics of Quinoa Grains: Evaluation of Bioactivity and Health Benefits by Combining In Silico Techniques With In Vitro Assays on Colorectal Adenocarcinoma Cells

Molecular Nutrition &Food Research, EarlyView.
Identifying health‐promoting molecules such as bioactive peptides in complex food mixtures is a major challenge. In this study, we investigated proteins and protein hydrolysates from four quinoa varieties to evaluate their potential anticancer effects on colorectal adenocarcinoma cells.
