ABSTRACT.- The identification of optimal rotation length of forest crops considering production and environmental perspectives is a major concern for eucalypts since plantations costs are high and nutrient extraction is considerable. This study assessed biomass productivity, energy yield and nutrient use efficiency of E. benthamii,E. dunnii and E. grandis plantations for energy purposes, with densities of 2220, 3330, 4440 and 6660 trees.ha−1 in the first rotation during a period of 76 months. Weight, content and extraction of nutrients, energy yield and efficiency of the use of nutrients in conversion to biomass and energy were measured in the stem with bark. The results showed a stabilization of biomass production, energy yield, and nutrient conversion efficiency between 49 and 57 months of age for all species and planting densities. During this time range, biomass productivity was notoriously reduced at higher planting densities (6660 vs. 2220 trees.ha−1), showing the convenience of using low densities. No relationship between productivity and efficiency of nutrient use was detected in the entire age range evaluated. E. benthamii and E. grandis were more efficient in converting nutrients to biomass and energy, while the three species showed similar productivity and energy yield. Productive and energetic sustainability can be enhanced by the optimization of rotation in eucalyptus crops in Uruguay. © 2022 Elsevier Ltd. All rights reserved. |

Abstract
The ability of an invasive species to establish is mostly determined by its biotic interactions with native species from the recipient community. Here, we evaluate the competitive effects and responses of the invasive Eragrostis plana when interacting with native species, in order to identify possible mechanisms driving invasion in Río de la Plata grasslands. A pairwise competition experiment was performed consisting of treatments that varied in the identity of neighbour plant species: (i) control (no interaction); (ii) intraspecific interaction; (iii) interspecific interaction between native and invasive species; and (iv) interspecific interaction between two co‐occurring native species. Data analysis was separated into the effect of E. plana on the performance of three native perennial grasses (target species: Aristida laevis, Eragrostis neesii and Paspalum notatum) and the response of E. plana to natives (target species: E. plana). Separately for each target species, components of plant performance were compared between neighbouring species treatments. We found that the strength of competitive interactions depended on both target and neighbour species identity. Regarding natives, interspecific competition was stronger than intraspecific. Native species showed distinctive responses to whether the neighbour was the invasive or a co‐occurring native (Eragrostis lugens). Competition between E. plana and native species was stronger than between co‐occurring natives. We demonstrated E. plana had a greater negative effect on native's species performance than the native congener E. lugens. Regarding E. plana, intraspecific competition was stronger than interspecific, and its response was positive or neutral when interacting with natives, suggesting its high tolerance to grow in competition with neighbours. We conclude E. plana's negative effects on native species performance, and its positive or neutral responses to neighbouring native plants demonstrate its strong competitive ability in the recipient community. This may explain its invasion success in southern Brazil and in the encompassing Río de la Plata grasslands. MenosAbstract
