Herbivore and plant invasions can modify the structure and functioning of ecosystems through positive interactions that facilitate their mutual establishment. An important consequence of the feeding behaviour of rabbits is that they can play a key role in seed dispersal by endozoochory. We examined the diet and potential for dispersing Rosa rubiginosa and R. canina (Rosa spp.) of European rabbits introduced in a semiarid protected area of Argentina. We found entire seeds in 100% of the samples of Rosa spp. analysed (n = 11, 187 pellets). Our results indicate that the passage of Rosa spp. seeds through the digestive tract of rabbits (64%) did not diminish their viability in comparison to the seeds taken directly from fruits (66%) (χ² = 0.09, p > 0.05). This study has identified new positive interactions between an invasive mammal and two invasive plants, a finding that suggests that these invader complexes could have a reciprocal effect on one another, which would potentially aid their invasive process in a semiarid protected area of Argentina.

草食动物和植物的入侵可以通过促进它们相互建立的积极相互作用来改变生态系统的结构和功能。兔子进食行为的一个重要结果是，它们可以在动物的内胚乳传播种子中发挥关键作用。我们研究了在阿根廷半干旱保护区引入的欧洲兔的Rosa Rubiginosa和R. canina（Rosa spp。）的饮食和散布潜力。我们在100％的Rosa spp样品中发现了整个种子。分析（n = 11，187粒）。我们的结果表明，罗莎的传球spp。通过兔的消化道（64％）的种子并没有减少它们的生存力相比于直接从水果（66％）所采取的种子（χ ²  = 0.09，p  > 0.05）。这项研究确定了一种侵入性哺乳动物与两种侵入性植物之间的新的积极相互作用，这一发现表明这些入侵者复合物可能相互产生互惠作用，这可能有助于它们在阿根廷半干旱保护区的侵入过程。
