Flexibilization or biomethane upgrading? Investment preference of German biogas plant operators for the follow-up of guaranteed feed-in tariffs
<p><span>This dataset reports the results of a discrete choice experiment with 183 German biogas plant operators designed to elicit the respondents' plans for biogas utilization pathways after the end of guaranteed feed-in tariffs. Participants could choose between 'flexibilization' for demand-based electricity generation and conversion to biomethane upgrading for direct feed-in into the natural gas grid. A binomial logit model revealed a 37% probability of switching to biomethane upgrading. These plants are characterized by higher capacities, several involved shareholders, secured succession, costly digestate disposal and belonging to the upper performance quartile. Mixed logit estimations conducted separately for the two investment concepts revealed a very high overall willingness to invest: 71% for flexibilization and 82% for biomethane upgrading. The respondents demand a return on investment of 19% for flexibilization and 26% for biomethane upgrading. Within the flexibilization, twofold overbuilding (installed capacity equals 2 times the rated power) is clearly preferred to fivefold overbuilding. For the biomethane upgrading, private ownership of the upgrading plant is preferred to a joint investment in a central upgrading facility. Limiting the use of energy crops reduces the propensity to invest in both models, while a longer utilization period enhances it. The respondents consider lack of planning reliability as the biggest obstacle to invest, followed by long approval procedures and high investment costs due to restrictive legal requirements.</span></p>

Top-down cascading effects of seed-feeding beetles and their parasitoids on plants and leaf herbivores
<p><span>When feeding on a plant, herbivorous insects alter the quality of the plant as a food source. This affects other organisms interacting with the same plant. These so-called 'plant-mediated interactions' can be altered by parasitoids that attack the herbivores. So far, this research area has mainly focused on interactions at the leaf level, and very little is known about plant-mediated interactions via seeds. </span><span>It is still poorly understood if seeds that survive insect damage have fewer resources to allocate to plant growth and defence against leaf herbivores, and whether parasitoids that kill seed-feeding insects mitigate such negative effects.</span></p> <p><span>Using seeds of wild lima bean plants (<em>Phaseolus lunatus</em>) we studied the effect of the intensity of infestation by seed beetles (<em>Zabrotes subfasciatus</em>) and their parasitoids (<em>Stenocorse bruchivora</em>) on the following parameters under lab conditions: seed mass and germination, plant growth and defensive compounds (cyanogenic glycosides and flavonoids) and performance of a leaf herbivore species (<em>Spodoptera latifascia</em>). In addition, we performed a field experiment using seeds with or without insect damage to investigate the consequences on plant performance and fitness in the wild.</span></p> <p><span>Seed beetle infestation had an overall negative impact on seed germination. Lab experiments revealed that damaged seeds produced plants with slower growth and reduced concentration of defensive compounds, which increased the performance of the leaf herbivores. Effects of seed-feeding on seed germination and plant growth were attenuated by parasitism, resulting in a net increase of the number of viable offspring. In the field, we observed that seed damage impaired germination, delayed flowering time and increased leaf herbivory.</span></p> <p><span>Our results show that plant-mediated interactions between insect herbivores are not limited to leaf herbivores but extend to seed herbivores. In our study system, parasitoids had no apparent effect on these interactions, despite their strong beneficial effects on germination and plant performance. These findings confirm the long-lasting consequences of indirect plant-mediated interactions in a community-wide ecological context. Furthermore, they contribute to a better understanding of the important but understudied effects of parasitoids on plant fitness.</span></p>
