研究人员在亚马逊西部发现了一个此前未被记录的青蛙物种，并将其命名为Adenomera varcena1。这一新物种在上胡鲁亚河地区、莫瓦河和克罗亚河附近被发现，靠近克鲁泽罗多南1。圣保罗州立大学教授Célio F. B. Haddad和米纳斯吉拉斯联邦大学教授Thiago R. Carvalho领导的研究团队通过DNA分析、独特的鸣叫声和形态学特征将其与近似物种区分开来1。该新种的前臂下侧没有黑点，具有独特的缓慢节奏鸣叫声1。
这项发现具有生态学意义，因为Adenomera varcena栖息于季节性泛滥森林，这对通常与干旱森林相关的Adenomera属来说是罕见的1。研究成果已发表在《Ichthyology & Herpetology》期刊上1。Carvalho表示："由于我们还不详细了解该物种的生态需求和自然历史，很难预测气候变化的影响"1。Haddad指出："目前，生态系统破坏的速度超过了分类学研究的速度"1。这一发现突显了亚马逊生物多样性的丰富程度，以及在物种灭绝前被正式命名的紧迫性1。
Researchers have identified a previously unknown frog species in the western Amazon, designated Adenomera varcena 1. The discovery was made in the seasonally flooded forests near the upper Huruaia River region, close to Cruzeiro do Sul and adjacent to the Moa and Croa rivers 1. Scientists distinguished the new species through DNA analysis, its distinctive slow-paced vocalization, and morphological characteristics, including the absence of black spots on the underside of its forearms 1.
The finding was formally published in Ichthyology & Herpetology and represents a significant addition to the Amazon's documented biodiversity 1. Leading the research were Célio F. B. Haddad, a professor at São Paulo State University, and Thiago R. Carvalho, a professor at the Federal University of Minas Gerais 1. Notably, Adenomera varcena inhabits seasonally flooded forests, an unusual habitat for a genus typically associated with arid woodlands 1. According to Carvalho, "since we still do not have a detailed understanding of the species' ecological requirements and natural history, it is difficult to predict the impacts of climate change" 1. Haddad underscored the urgency of taxonomic work, stating that "at present, the rate of ecosystem destruction exceeds the pace of taxonomic research" 1.
