基于线粒体ND1和16S rRNA基因序列探讨中国蝴蝶12科的系统发育关系(鳞翅目: 双孔次亚目: 蝶类)

对中国12科共32种代表蝶类的ND1基因和16S rRNA 基因进行了序列测定（包括新测30种ND1基因和9种16S rRNA基因）和比较分析, 同时采用邻接法、最大似然法和贝叶斯法构建了12科蝶类的系统发育树, 探讨了其高级分类群的系统发育关系。序列分析的结果显示: 经比对处理后的两个基因总长度为869 bp, 其中保守位点373个, 可变位点496个, 简约信息位点375个; A+T的平均含量为80.2％, 明显高于C+G的平均含量19.8％。分子系统树表明: 蛱蝶科不是单系群; 珍蝶类、斑蝶类和喙蝶类位于蛱蝶科内; 粉蝶科和凤蝶科具有共同祖先。据此建议: 绢蝶科应归入凤蝶科; 蚬蝶科归入灰蝶科; 珍蝶类、斑蝶类和喙蝶类作为蛱蝶科中的亚科, 眼蝶类从蛱蝶科中分离出来独立成科。另外, 环蝶类的系统分类地位还有待于进一步研究。

Ants benefit from attending facultatively myrmecophilous Lycaenidae caterpillars: evidence from a survival study

Workers of three ant species (Lasius niger, Lasius flavus, Myrmica rubra) were caged in the laboratory together with caterpillars and pupae of five species of lycaenid butterflies. Mortality of ants was 3–5 times higher when the ants were confined with larvae lacking a dorsal nectar organ (Lycaena phlaeas, Lycaena tityrus) rather than with caterpillars which possess a nectar gland (Aricia agestis, Polyommatus bellargus, P. icarus). For all five species, ant survival was always lower at the pupal stage (where a nectar organ is always absent) than at the caterpillar stage and was largely equivalent for the butterfly species tested. The experimental data confirm earlier estimates that ants can derive nutritive benefits from tending facultatively myrmecophilous lycaenid caterpillars, even though these caterpillars produce nectarlike secretions at low rates.     

Latitudinal gradients in butterfly body sizes: is there a general pattern?

We tested for the existence of latitudinal gradients in the body sizes of butterflies in North America, Europe, Australia and the Afrotropics. We initially compared body sizes (measured as male forewing length) of all butterflies found in 5° latitudinal bands in each region, and then evaluated the relationship between body size and latitude statistically using the latitudinal midpoint of each species' distribution. Trends were examined for species in all butterfly families together and for each family separately. We found that gradients in body sizes were inconsistent in different geographical regions and butterfly families; in some cases species were larger towards the tropics, in some they were smaller, and in other cases there were no relationships. Most of the gradients, when they existed, reflected between-family effects arising from changes in the relative numbers of species in each family across regions. We conclude that general ecological explanations for geographical trends in butterfly body sizes are inappropriate, and gradients largely reflect historical patterns of speciation within and between taxa in each biogeographical realm. Thus, the robustness of body size gradients found in other insect groups should be confirmed in future studies by including more than one geographical region whenever possible.

Direct and indirect effects of multiple enemies on water strider mating dynamics

Many different measures of range size are used for both empirical and conservation purposes. The possible consequences of the particular methods used in determining observed patterns of results are seldom considered. Using species of butterflies and freshwater molluses in Britain, we investigate the relationship between the range sizes measured by nine different methods and the sets of rare species they distinguish. A comparison of range sizes measured at different scales. Britain and Europe, is also made for the butterflies. We find that for many studies involving range size the various measures of range size are interchangeable. With respect to the identification of rare species the results are not as clear.

Morphological grouping of Mexican butterfliesin relation to habitat association

Current rates of destruction of natural ecosystems call for rapid and efficient ways of assessing the successional state or degree of perturbation, and of monitoring management efforts. In this paper we propose that butterfly species, grouped by morphological and ethological traits, can be used for these purposes. The groups, each composed of species from many taxa, appear to be strongly correlated with types of habitat. We re-define the groups originally distinguished by de la Maza and de la Maza (1988), and, using data from Quintana Roo and Morelos states in Mexico, show a statistical association between certain coloration groups and types of habitat. The existence of such consistent, non-taxonomic groupings is of theoretical interest and may also be used to monitor habitats or to predict the effects of disturbance.     

An analysis of the phenotypic effects of certain colour pattern genes in Heliconius (Lepidoptera: Nymphalidae)

The colour patterns of Heliconius butterflies are built up from an array of serially homologous pattern elements known as the nymphalid groundplan. An analysis of the phenotypic effects of ten genetic loci from H. melpomene and H. cydno reveals that each alters the expression either of a single element of the groundplan or of an entire row of serially homologous elements. Five of the ten loci affect the size (or presence/absence) of specific pattern elements, two affect the colour in which a pattern element is expressed, two affect pattern-inducing activity of the wing veins, and one appears to affect an overall threshold for pattern determination. Three of the ten loci have identical effects on homologues of the fore- and hindwing. We show that most of the apparently large and qualitative phenotypic effects of these genes can be readily explained by relatively small and quantitative changes in the dimensions or positions of specific pattern elements.
