This paper seeks to investigate the impact of ambidexterity (exploration and exploitation) on green product innovation and the success of new products through the effects of sustainability, considering the moderating role of customer pressure. This research proposes a theoretical model that was tested using structural equation modelling (SEM) and a multigroup analysis to understand the moderating role of customer pressure. A 23‐item questionnaire was developed to explore the proposed relationships, applied in two different moments, answered by two other critical respondents from each company. At the end of the second collection moment, 336 valid questionnaires were collected from a sample of industrial SMEs in Portugal. The results show a positive influence of ambidexterity on sustainability and, therefore, on new product success and green product innovation. In addition, green product innovation increases the success of new products due to the growing demand for more sustainable products. Furthermore, the chain of effects between ambidexterity and further product success was strengthened when customer pressure was higher. This study stresses the need to actively manage exploration and exploitation investments to enhance ambidexterity, especially when sustainability and green innovation are the expected outcomes. The originality of this research is related to the contributions of hierarchical dynamic capabilities, combining and balancing exploration and exploitation, to produce successful ambidextrous companies in sustainability and green strategies.

Despite worldwide proliferation of the genus Caulerpa and subsequent effects on benthic communities, little is known about the nutritional physiology of the Caulerpales. Here, we investigated the uptake rates of ammonium, nitrate, amino acids, and phosphate through the fronds and rhizoids + stolon, the internal translocation of nitrogen, and developed a nitrogen budget for the rapidly spreading Caulerpa prolifera in Ria Formosa lagoon, southern Portugal. Caulerpa prolifera acquired nutrients by both aboveground and belowground parts at similar rates, except nitrate, for which fronds showed 2‐fold higher uptake rates. Ammonium was the preferential nitrogen source (81% of the total nitrogen acquisition), and amino acids, which accounted for a significant fraction of total N acquisition (19%), were taken up at faster rates than nitrate. Basipetal translocation of 15N incorporated as ammonium was nearly 3‐fold higher than acropetal translocation, whereas 15N translocation as nitrate and amino acids was smaller but equal in either direction. The estimated total nitrogen acquisition by C. prolifera was 689 μmol · m−2 · h−1, whereas the total nitrogen requirement for growth was 672 μmol · m−2 · h−1. The uptake of ammonium and amino acids by belowground parts accounted for the larger fraction of the total nitrogen acquisition of C. prolifera and is sufficient to satisfy the species nitrogen requirements for growth. This may be one reason explaining the fast spreading of the seaweed in the bare sediments of Ria Formosa where it does not have any macrophyte competitors and the concentration of nutrients is high.
