Egg and larval production of Eastern Baltic cod in captivity over one spawning season
Abstract Eastern Baltic cod (Gadus morhua) has experienced a dramatic decline in biomass, distribution, size and condition over recent decades, related to a combination of fishing pressure and environmental stressors. Reduced parental size and condition are known to impact reproductive success, affecting egg quality, fertilization and hatching success ...

Auxin response and PIN‐mediated transport in chlorophyte algae
Like multicellular plants, green algae respond to auxin and move it across their cells. However, their PIN‐like proteins do not act like plant auxin exporters, suggesting that basic auxin transport evolved early and specialized directional transport appeared later in plant evolution.

ABSTRACT Salt stress and nitrogen utilisation efficiency (NUE) represent critical constraints affecting worldwide crop productivity. While nitrate transporter proteins (NPFs) have been implicated in saline chloride (Cl−) ion transport, the mechanistic linkage between chloride stress and NUE remains poorly understood.

The CaM1‐CBP60b‐MYB77 Transcriptional Cascade Regulates K+ Homeostasis and Salt Tolerance in Barley
ABSTRACT Soil salinity is a major abiotic stress that threatens global crop productivity. Calcium (Ca2+) is a pivotal second messenger in plant stress signalling, but how Ca2+ sensors such as calmodulin (CaM) transcriptionally control ion homeostasis and salt tolerance remains largely understood in crops.

Mesophotic octocoral larval settlement preferences and behaviors
Abstract Introduction Lab‐based coral reproduction is advancing restoration efforts to support coral populations injured by the 2010 Deepwater Horizon oil spill. Objectives This study aimed to answer foundational questions concerning coral spawning and larval settlement that need to be resolved for these mesophotic and deep‐sea coral species before ...

Fertilization failure and oocyte activation
Recent reports have suggested that when unfertilized oocytes with a sperma-tozoon after intracytoplasmic sperm injection (ICSI) are properly activated, the activated oocytes develop normaly similar to fertilized oocytes. However, human oocytes do not easily respond to universal activators of mammalian oocytes like ethanol or calcium ionophore A23187 ...

Women in space: A review of known physiological adaptations and health perspectives
Abstract Exposure to the spaceflight environment causes adaptations in most human physiological systems, many of which are thought to affect women differently from men. Since only 11.5% of astronauts worldwide have been female, these issues are largely understudied.
