IntroductionThe paper by Al-Sheikhly et al. (2013) described many novel observations that aimed to expand our understanding of the biology of the Basra Reed Warbler Acrocephalus griseldis, a poorly known species of considerable conservation concern (it being currently treated as Endangered by IUCN). However, we believe that significant problems concerning the methodology underlying the data stated to have been collected severely compromise the stated importance of their work, and must raise considerable doubts with respect to at least some of their conclusions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
