  3. Seasonal variation in the balance and strength of cooperative and competitive behavior in patches of blue mussels

    • PLOS ONE
    • by Jacob J. Capelle, Eva Hartog, Tony Wilkes, Tjeerd J. Bouma Aggregation into groups may affect performance of individuals through the balance and strength of facilitative versus competitive interactions. We studied in situ how seasonal variation in abiotic environment affects this balance for blue mussels, a semi-sessile species. We hypothesize that seasonal variation in stresses and resources affects the strength of the interaction.

  10. Food waste quantities and composition in Polish households

    • Waste Management & Research
    • Over one-third of the produced food is wasted globally. Most food is wasted at the consumer stage. The use of waste sorting analysis is considered to deliver more precise and less biased results than self-reporting methodologies. Currently, no detailed studies on the amounts and composition of household food waste are available for Poland. In the current paper the results of a food waste generation study in the city of Opole in Poland are presented.

  12. Seasonal differences in softening of early-harvested ‘Royal Gala’ apple fruit are correlated with at-harvest biomarkers indicative of abiotic stress responses

    • Postharvest Biology and Technology
    • Softening of apple fruit depends on maturity at harvest and a range of orchard and environmental factors. We investigated seasonal effects on ‘Royal Gala’ storage performance independent of maturity and separate from potential orchard effects. In two consecutive seasons, fruit were harvested at four times: very early (H1), early (H2), commercial (H3) and late (H4), and were cold-stored at 0.5 °C for 100 d followed by a shelf-life period.
