🌳From Biosystems Engineering: New yield-mapping method separates mixed almond harvest flows into individual tree yields without slowing harvesting.(Juan Villacrés, Patrick H. Brown, Y. Jin, J. L. Zarate-Valdez, M. A. Germani, R. Camargo, Stavros G. Vougioukas) ▶️ www.sciencedirect.com/science/arti...
Fig. 4. Graphical representation of almond flow mixing from three consecutive trees. The almonds are shaken from each tree and deposited onto the conveyor belt, where mixing occurs. Each tree has a distinct, actual volume flow that is not directly measurable; the measurable component represents the combined mixed flow of all three trees.

🌱 From Soil Biology and Biochemistry: Oak death reshaped deep-soil microbial functions within three years, potentially altering how savanna soils cycle carbon as tree mortality increases. (Anna C. Goodman, Ernest N. Walker, Glade D. Bogar, Laura M. Bogar) ▶️ www.sciencedirect.com/science/arti...
Fig. 4. Rolling averages of fungal biomass (ng PLFA/g soil) over depth by assigned functional group. Black points are measurements of fungal phospholipid fatty acids (PLFAs)/g soil, used here as a proxy for total fungal biomass. The black curve is a local regression connecting the mean fungal PLFA measurements at each depth. Other points represent each soil core's “imputed biomass” of fungi belonging to a given functional group (denoted by color). Imputed biomass is the proportion of the total fungal community (as described by ITS rRNA metabarcoding) assigned to a given functional group multiplied by the total fungal biomass as measured by PLFA. Functional groups were assigned to ASVs based on “primary lifestyle” denoted in the FungalTraits database and further agglomerated for visual simplicity. All local regressions were fitted using the “loess” method to geom_smooth() in ggplot2.

Interactions include a prediction line for the lowest and highest values for each interaction factor (see legends). Fixed effects include: (A) individual tree diameter at breast height (dbh); (B) quadratic mean diameter (QMD); (C) dbh * average snowpack Nov-Mar; (D) dbh * average precipitation Apr-Aug prior year. Each x-axis displays scaled levels of the explanatory variable.

🌱 From Current Opinion in Plant Biology: Malate may play a bigger role in photosynthesis than once thought, helping plants balance carbon storage and protein production as CO2 rises. (Arnold J. Bloom) ▶️ www.sciencedirect.com/science/arti... #PlantScience #PlantBiology
Figure 1. C3 carbon fixation and photorespiration within the context of photosynthetic carbon, oxygen, organic acid, and nitrogen metabolisms within a C3-species leaf cell. Solid black and red lines represent reactions of the traditional pathways, solid blue lines represent reactions of several proposed photorespiratory pathways, solid purple lines represent reactions for amino acid synthesis, and dotted lines represent associated transport processes. The following enzymes catalyze the numbered reactions: 1. rubisco; 2. phosphogluconate dehydrogenase; 3. NADP-malic enzyme; 4. malate dehydrogenase; 5. phosphoenolpyruvate carboxylase; 6. pyruvate:phosphate dikinase; 7. phosphoribulokinase; 8. phosphoglycolate phosphatase; 9. glycolate oxidase; 10. glutamate:glyoxylate aminotransferase; 11. glycine decarboxylase complex; 12. serine hydroxymethyltransferase-1; 13. serine:glyoxylate aminotransferase; 14. hydroxypyruvate reductase-1; 15. glycerate kinase; 16. glucose-6-phosphate dehydrogenase; 17. 6-phospho-gluconolactonase; 18. malate dehydrogenase; 19. nitrate reductase; 20. nitrite reductase; and 21. glutamine synthetase. PETC and RETC designate photosynthetic and respiratory electron transport chains, respectively. TrioseP includes GAP and DHAP. The overall reaction for one of the proposed photorespiratory pathways in chloroplasts (1–3 & 7) is RuBP + 6 PG + O2 → RuBP + glycolate + malate; the overall reaction for the other proposed photorespiratory pathway (1 & 4–6) is RuBP + O2 + HCO3– + NADPH → glycolate + malate + NADP+ + H+.

PCA showing climate change at the home sites for the water year. Arrows show the change from historical (1964–1993) to recent (1994–2023) climate means at each population home site. The arrow for the shift in climate at the WL2 population is circled and labelled. Diamonds represent the garden climate in 2023 and 2024. PC1 represents a cold/warm (left/right; BIO1), snow/no snow (left/right; PCK) continuum while PC2 represents a dry/wet (bottom/top; CWD) and temperature annual range (bottom to top: Low to high; BIO7) continuum (see Table S2). There are significant shifts in PC space from historical to recent climate (Table S3).
