title: Variation in defensive traits against herbivores of native and invasive populations of Carpobrotus edulis

description: The Enemy Release Hypothesis (ERH) predicts that the escape from natural enemies, such as specialist herbivores, may explain the invasiveness of some invasive alien plants, maximizing their investment in growth and reproduction. This release from natural enemies might decrease the investment in expensive defense mechanisms (i.e., digestibility reducers) against the attack of specialist enemies, whilst increasing the investment in defenses (i.e., cheap toxins) and tolerance against the attack of generalist herbivores, as exposed by the Shifting Defense Hypothesis (SDH). To test this, we conducted a greenhouse experiment to compare morphological and physiological traits of <em>Carpobrotus edulis</em>, collected in its native (South Africa) and introduced (Chile and Spain) ranges, attacked by the generalist spittlebug <em>Philaenus spumarius</em> and the specialist scale insect <em>Pulvinariella mesembryanthemi</em>. Our results do not support the ER and SD hypotheses. We found that <em>C. edulis</em> plants collected from native and introduced ranges showed no significant differences in growth and defensive compounds studied for both controls and those plants under attack by the generalist <em>P. spumarius</em> (i.e., showing no increase in biomass or changes in biochemical defenses). In contrast, the specialist herbivore <em>P. mesembryanthemi</em> induced the production of total phenols and tannins and reduced the growth and survival of <em>C. edulis</em> plants. Overall, we found strong evidence that <em>C. edulis</em> is negatively affected by the attack of its specialist herbivore, but not by that of generalist herbivore, regardless of origin. The observed tolerance to generalist herbivores suggests the intriguing possibility of trait selection, allowing <em>C. edulis</em> plants to tolerate generalist herbivores more than specialists.

title: Data underlying the research of Efficient Hydrothermal Pretreatment of Mixed PHA/PLA and Consequent Continuous Anaerobic Fermentation into VFA

description: Recycling biobased biodegradable plastics such as polyhydroxyalkanoates (PHA) and polylactic acid (PLA) is essential for developing a circular economy. This study presents an integrated strategy that combines batch hydrothermal processing at 150℃ with continuous open-culture fermentation to convert PHA and PLA into C<sub>2</sub>-C<sub>6</sub> carboxylates. Co-hydrolysis in a carboxylic acid solution significantly enhanced PHA depolymerization compared to PHA hydrolysis alone. Among various catalytical supplements, PLA addition notably improved PHA hydrolysis, achieving up to 91% dissolution. Throughout fermentation, acetate and <em>n</em>-butyrate were the primary products. In Phase VI, co-fermentation of PHA hydrolysates (~10 g/L 3-hydroxybutyrate) and PLA hydrolysates (5 g/L lactate) yielded acetate (4.4 g/L), <em>n</em>-butyrate (8.0 g/L), and <em>n</em>-caproate (0.3 g/L), while also reducing the need for KOH for pH control. An overall conversion efficiency of 89% from bioplastics to carboxylates was achieved, with a high <em>n</em>-butyrate selectivity of 71%. Supplementing with ethanol (7 g/L) further enhanced chain elongation, increasing <em>n</em>-butyrate concentration to 10.1 g/L, although excess ethanol oxidation was observed. This study demonstrates, for the first time, the successful continuous open-culture fermentation of PHA and PLA hydrolysates into carboxylates. Microbial community analysis identified <em>Clostridium tyrobutyricum</em> as a key species likely responsible for dominant <em>n</em>-butyrate production.

title: Phenotypic plasticity of invasive <i>Carpobrotus edulis</i> modulates tolerance against herbivores

description: The anthropogenic movement of species has favoured the introduction of invasive plants worldwide. Invasive plants are frequently released from their natural enemies; however, new associations with generalist herbivores may induce defence mechanisms of non-native plants. Defensive traits are often directly related to the highly competitive ability, but also to potential antagonisms and mutualisms that they can establish with soil microorganisms. Here, we examined whether the intraspecific competition and soil microorganism influence the morphological and physiological traits of Carpobrotus edulis when is being attacked by the native generalist snail Theba pisana. To achieve this, we grew two C. edulis individuals in separate and same pots filled with live or sterile sand, and with or without T. pisana. Our results indicated that herbivory induced an increase of shoot biomass in attacked C. edulis individuals (i.e., treated donor plants), as well as in un-attacked neighbouring individuals co-growing in the same pot (i.e., untreated recipient plants). Nevertheless, intraspecific competition or soil microorganisms did not affect the regular growth of C.edulis despite reduced physiological activity and damage caused by the herbivore. Overall, our findings revealed that C. edulis individuals tolerate snail attack by inducing a compensatory growth response, and probably emitting soil-mediated chemical alarms, which are identified and received by conspecifics neighbours. We conclude that phenotypic plasticity of invasive C. edulis favours tolerance against herbivores, but we also suggest that plant-plant communication probably determines the plant growth of un-attacked neighbouring C. edulis individuals, thus favouring their invasion mechanisms.

title: Data underlying the research of Mesophilic Fermentation Explorations for Anaerobic Carboxylates Production from Commercial Bioplastic Products: PHA-based ‘Happy Cups’ & PLA-based Lids

description: Biodegradable plastics such as polyhydroxyalkanoates (PHA) and polylactic acid (PLA) are increasingly applied in commercial products, but their end-of-life (EoL) processing remains inefficient in terms of carbon and energy recovery. Carboxylates, such as acetate and <em>n</em>-butyrate, are valuable platform chemicals that can serve as precursors for bioplastics, biofuels, and other biobased products. Producing carboxylates from biodegradable plastics offers a promising strategy to recover carbon and support circular EoL management beyond conventional options like composting or incineration. This study presents mesophilic open-culture fermentation strategies to convert commercial PHA and PLA raw materials and/or products into carboxylates. A sequential bioprocess was developed using a gas-lift anaerobic filter bioreactor, initiating in Phase I with batch fermentation of hydrolysates derived from hydrothermally pretreated PHA (10 g/L) and PLA (1.4 g/L) pellets. In Phase II, continuous operation produced 6.6 g/L acetate and 4.8 g/L <em>n</em>-butyrate from the same hydrolysates source. During Phase III, additional shredded commercial bioplastic products (PHA-based cups and PLA-based lids) were filled to co-ferment with hydrolysates, which further increased acetate and <em>n</em>-butyrate yields to 7.2 g/L and 5.5 g/L, respectively. In subsequent phases, hydrolysates feeding was stopped, and only the remaining solid bioplastics were used. The hydraulic retention time was extended from 2 to 18 days in Phase V. Overall, 35% of the PHA-based cups were converted into carboxylates, while PLA-based lids showed negligible degradation. Residual plastics were partially fragmented into microplastics. Microbial community analysis revealed that <em>Clostridium tyrobutyricum</em> likely played a key role in the hydrolysates fermentation of PHA and PLA pellets, while a broader microbial consortium contributed to solid bioplastic conversion.
