生境丧失和气候变化正在迅速改变自然生境，从而增加了脆弱物种扩散能力的重要性。飞行是许多昆虫传播所必需的，传播能力的差异可能反映了飞行肌肉有氧能力的差异。在一个大型集合种群的格兰维尔贝母蝴蝶在芬兰的奥兰群岛，成年人之间的小地方人口分散频繁。在新建立的种群中发现的个体比老种群中的蝴蝶具有更高的飞行代谢率和实地测量的扩散距离。为了评估可能存在的差异，在飞行肌肉有氧能力之间的格兰维尔贝母种群，酶活性和组织浓度的线粒体蛋白质细胞色素-c氧化酶（CytOx）进行了测量和比较与其他四种蛱蝶。飞行肌肉结构和线粒体密度也在格兰维尔贝母和一个长距离的移民，红色的海军上将。新种群的格兰维尔贝母比旧种群的个体有显着更高的有氧能力。不同种类的蝴蝶相比，飞行能力强的蝴蝶飞行肌CytOx含量和酶活性高于短距离飞行的蝴蝶，红海军上将的飞行肌线粒体比格兰维尔贝母的大且多。这些结果表明，优越的上级分散能力的蝴蝶在新的种群的格兰维尔贝母是由于更大的有氧能力，虽然这个物种有一个低的有氧能力一般相比，已知的强传单。低有氧能力可能会限制扩散能力的格兰维尔贝母。
Habitat loss and climate change are rapidly converting natural habitats and thereby increasing the significance of dispersal capacity for vulnerable species. Flight is necessary for dispersal in many insects, and differences in dispersal capacity may reflect dissimilarities in flight muscle aerobic capacity. In a large metapopulation of the Glanville fritillary butterfly in the Åland Islands in Finland, adults disperse frequently between small local populations. Individuals found in newly established populations have higher flight metabolic rates and field-measured dispersal distances than butterflies in old populations. To assess possible differences in flight muscle aerobic capacity among Glanville fritillary populations, enzyme activities and tissue concentrations of the mitochondrial protein Cytochrome-c Oxidase (CytOx) were measured and compared with four other species of Nymphalid butterflies. Flight muscle structure and mitochondrial density were also examined in the Glanville fritillary and a long-distance migrant, the red admiral. Glanville fritillaries from new populations had significantly higher aerobic capacities than individuals from old populations. Comparing the different species, strong-flying butterfly species had higher flight muscle CytOx content and enzymatic activity than short-distance fliers, and mitochondria were larger and more numerous in the flight muscle of the red admiral than the Glanville fritillary. These results suggest that superior dispersal capacity of butterflies in new populations of the Glanville fritillary is due in part to greater aerobic capacity, though this species has a low aerobic capacity in general when compared with known strong fliers. Low aerobic capacity may limit dispersal ability of the Glanville fritillary.
