This Science in Developing Countries award will support travel to Chile and Paraguay, per diem, and materials associated with the dissertation research of R. Eduardo Palma, a Chilean doctoral student working under Donald Duszynski at the University of New Mexico. The project aims to evaluate phylogenetic relationships within the marsupial genus Thylamys, using molecular analytical methods of allozyme variation and mtDNA. The molecular data are expected to elucidate evolutionary relationships within the genus, since most studies have been limited to morphologic and chromosomic analyses. The research also will likely provide results needed to develop conservation strategies in the Neotropics, a region in which research in systematic mammalogy is critical. Both the U.S. and Chilean sides will benefit from new advances in South American biogeography. The Chilean side will benefit from dissertation research support, which will enhance collaborative ties between the U.S. and South America, the region's scientific infrastructure, and its capacity for basic biological research.

这一发展中国家科学奖将按日资助前往智利和巴拉圭的旅行，以及与R·爱德华多·帕尔马的论文研究相关的材料。帕尔马是智利博士生，在新墨西哥大学唐纳德·杜辛斯基手下工作。该项目旨在利用等位酶变异和线粒体DNA的分子分析方法，评估有袋类动物Thylamys属内的系统发育关系。分子数据有望阐明该属内部的进化关系，因为大多数研究仅限于形态和染色体分析。这项研究还可能提供在新热带地区制定保护战略所需的结果，在该地区，系统哺乳动物学的研究至关重要。美国和智利双方都将受益于南美生物地理学的新进展。智利方面将受益于论文研究支持，这将加强美国和南美之间的合作关系，这是该地区的科学基础设施，以及其基础生物学研究的能力。
