Published: Dec. 3, 2024

Microalgae offer a promising solution for enhancing agricultural sustainability and mitigating global warming. When extracts from algal cells their spent medium are used as biostimulants on crop seeds, they can significantly influence plant physiology. This application boosts productivity improves tolerance to abiotic stress. The objective of this study was evaluate the biostimulant potential crude Tetradesmus obliquus, Chlamydomonas reinhardtii, Auxenochlorella protothecoides, consortium, well growth media, when applied tomato seeds (Solanum lycopersicum). assessed germination indexes seed development, including weight, root/shoot ratio, speed. results indicated that variation in morphology treated primarily influenced by concentration extracts, with species having lesser impact observed variability. number germinated notably higher at lowest biostimulants. Additionally, exhibited greater than media. Furthermore, analysis speed revealed most seedlings grew faster control seeds. Lastly, reported lower consortium compared single species, possibly due co-cultivation different species.

Sibling Species with Different Distributions Around a Co2 Vent Show Proteomic Remodelling Upon Transplantation, While Displaying Unique Metabolite and Lipid Signatures Associated with Their Regimes of Origin

Published: Jan. 1, 2023

How marine organisms respond to ongoing global change will dictate their developmental trajectory, performance, survival and fitness, ultimately biogeography in the future ocean. Physiological adjustments are key buffering negative impacts caused by changing conditions, maintaining homeostasis, although whole organism responses can vary from those at cellular molecular level. Studying physiological of closely related species inhabiting different environments help us understand extent species’ ability for acclimatisation under natural they may utilise changes. In this study we conducted reciprocal situ transplant experiments a CO2 vent (Ischia, Italy), using sibling annelid Platynereis c.f. dumerilii (found mainly outside vent, known undergo an extreme reduction metabolic rates when exposed high pCO2 conditions) massiliensis inside be able maintain higher conditions). Following transplantations, characterised each individual response its proteome, metabolome, lipidome, short or long term, low conditions whilst confirming genetic identity. By integrating information on biomolecules omics levels demonstrate that level mechanisms utilised spp. regimes with shown conserved across species. Responses metabolome lipidome were dependent regime origin, changed relatively slowly, whereas proteome type quickly comparison. Our results provide new insights improve our understanding interplay between involved defining functional phenotype species, acclimatise conditions.

Response to visual and mechano-acoustic predator cues is robust to ocean warming and acidification and is highly variable in European sea bass

Frontiers in Marine Science, Journal Year: 2023, Volume and Issue: 10

Published: Oct. 18, 2023

Predator-prey interactions and, especially, the success of anti-predator responses are modulated by sensory channels vision, olfaction, audition and mechanosensation. If climate change alters fish ability to avoid predation, community dynamics can be affected. We investigated whether mid-duration exposure warming and/or acidification behavioural response visual or mechano-acoustic predator cues in juvenile Dicentrarchus labrax . measured kinematic variables before after a challenge which mimicked an overflying bird shadow swoop attack, respectively. Due large interindividual variability cue presentation, were categorized as slow fast account for baseline individual variability. Treatment did not impact both every treatment elicited precautionary escape responses. Interestingly, even swam cue, suggesting that regardless initial category, managed facing danger. Anti-predator varied according level threat survival with greater attack. Although wild sea bass aggregate schools, school rely on single leaders highlights importance behaviours. demonstrated D. is robust independent combined effects acidification. robustness confirmed over long-duration, it could provide evolutionary advantage future ocean, where transmission through changing environments further modulate perception predator-prey interactions.
