First record of amaranthus viridis after over 25 years

Introduction

First record of amaranthus viridis after over 25 years. Rediscovery of Amaranthus viridis in Romania after 25+ years. Learn about its morphology, distribution, biology, ecology, and invasiveness, a species native to South America.

Abstract

We report the presence of Amaranthus viridis after over 25 years from the last mention. The species is native to South America and in Europe is naturalized or casual. The way of introduction in Romania is unknown. We provide information about its morphological features, distribution, biology, ecology and invasiveness.

Review

This manuscript reports the rediscovery of *Amaranthus viridis* in Romania after an absence of over 25 years, a significant finding for regional floristic records. The authors aim to provide essential information regarding the species' morphological features, distribution, biology, ecology, and invasiveness. Such updated records are crucial for monitoring changes in local biodiversity and understanding the dynamics of non-native species, particularly those with potential invasive tendencies. The strength of this submission lies in its contribution to local phytogeography by addressing a clear gap in species observation for an extended period. The intention to provide comprehensive background information on the species' characteristics is commendable. However, the abstract currently lacks crucial methodological details. It does not specify how this 'first record' was established, the extent of the observation (e.g., single individual, established population), or the methods used to gather the biological and ecological information presented. Clarification on the source of this information (original fieldwork, synthesis of existing literature, or both) would significantly strengthen the paper's foundation. Given the importance of documenting such reappearances, this manuscript holds merit, likely as a floristic note or short communication. To enhance its impact, the authors should explicitly detail their methodology, including collection efforts, identification confirmation, and site descriptions. Furthermore, exploring potential reasons for its 25-year absence and subsequent reappearance, even if speculative, would add valuable context. A discussion on the implications of its presence for local ecosystems or agriculture, beyond merely stating its invasiveness, would also be beneficial. I recommend a revision addressing these points to elevate the scientific contribution of the work.
