With the loss of global biodiversity, signals of the speciation process are progressively being erased as populations dwindle and species disappear. We propose to develop and implement an integrative approach that will draw from new advances in computational biology, field ecology, and population genomics. We anticipate that our approach will be broadly applicable to other non-model biological systems, especially those that diverged recently and rapidly and for which species boundaries are cryptic. Our findings, as well as in-country collaboration, will have immediate relevance to conservation policy in the ecologically complex and poorly studied regions of Southeastern Madagascar.

随着全球生物多样性的丧失，随着种群的减少和物种的消失，物种过程的信号被逐渐消除。我们建议开发和实施一种综合方法，该方法将从计算生物学，现场生态学和人群基因组学方面的新进展中汲取灵感。我们预计我们的方法将广泛适用于其他非模型生物系统，尤其是那些最近，迅速差异的且物种边界的隐密性的生物系统。我们的发现以及国内合作将与马达加斯加东南部的生态复杂且研究不足的地区的保护政策直接相关。
