Impacts of ocean acidification and warming on post-larval growth and metabolism in two populations of the great scallop (Pecten maximus).

Ocean acidification and warming are key stressors for many marine organisms. Some organisms display physiological acclimatization or plasticity, but this may vary across species ranges, especially if populations are adapted to local climatic conditions. Understanding how acclimatization potential varies among populations is therefore important in predicting species responses to climate change.

Influence of Demographic Factors on Clinical Outcomes in Adults With Chronic Idiopathic Constipation Treated With Plecanatide.

Introduction: Chronic idiopathic constipation (CIC) is a common condition that affects some patient groups more often. Demographic/clinical characteristics can differ in presentation and therapeutic response. The impact of these characteristics on plecanatide efficacy/safety was examined.

Fate of C-MSMA in a soil column study simulating herbicide use environments.

Monosodium methanearsonate (MSMA), a selective contact herbicide, is a sodium salt of monomethyl arsenic acid (MMA or MAA). This paper focuses on the environmental fate of MMA. Decades of research have shown that a significant portion of applied MSMA drips to soil and is sorbed quickly.

Microbiota of the Digestive Glands and Extrapallial Fluids of Clams Evolve Differently Over Time Depending on the Intertidal Position.

The Manila clam (Ruditapes philippinarum) is the second most exploited bivalve in the world but remains threatened by diseases and global changes. Their associated microbiota play a key role in their fitness and acclimation capacities. This study aimed at better understanding the behavior of clam digestive glands and extrapallial fluids microbiota at small, but contrasting spatial and temporal scales.

Study of Synthesis Pathways of the Essential Polyunsaturated Fatty Acid 20:5n-3 in the Diatom Using C-Isotope Labeling.

The present study sought to characterize the synthesis pathways producing the essential polyunsaturated fatty acid (PUFA) 20:5n-3 (EPA). For this, the incorporation of C was experimentally monitored into 10 fatty acids (FA) during the growth of the diatom for 24 h preferentially and quickly incorporated C into C PUFAs such as 18:2n-6 and 18:3n-6 as well as 16:0 and 16:1n-7, which were thus highly C-enriched. During the experiment, 20:5n-3 and 16:3n-4 were among the least-enriched fatty acids.
