A diverse array of molecular markers and constantly evolving analytical approaches have been employed to reconstruct the invasion histories of the most notorious inva-sions. Detailed information on the source(s) of introduction, invasion route, type of vectors, number of independent introductions and pathways of secondary spread has been corroborated for a large number of biological invasions. In this review, I present the promises and limitations of current techniques while discussing future directions. Broad phylogeographic surveys of native and introduced populations have traced back invasion routes with surprising precision. These approaches often further clarify spe-cies boundaries and reveal complex patterns of genetic relationships with noninvasive relatives. Moreover, fine-scale analyses of population genetics or genomics allow deep inferences on the colonization dynamics across invaded ranges and can reveal the extent of gene flow among populations across various geographical scales, major demo-graphic events such as genetic bottlenecks as well as other important evolutionary events such as hybridization with native taxa, inbreeding and selective sweeps. Genetic data have been often corroborated successfully with historical, geographical and ecological data to enable a comprehensive reconstruction of the invasion process. The advent of next-generation sequencing, along with the availability of extensive da-tabases of repository sequences generated by barcoding projects opens the opportunity to broadly monitor biodiversity, to identify early invasions and to quantify failed inva-sions that would otherwise remain inconspicuous to the human eye.

Abstract As the highest and largest plateau in the world, the Qinghai–Tibet Plateau, with its numerous endemic species, is one of the important alpine biodiversity hotspots. Only recently have the evolutionary histories and underlying adaptations of these alpine plants become clear, through research mostly based on testable experiments and analyses. In this issue, we collected a total of 13 papers related to such aims. In addition, we selected a few published papers to highlight the major findings in the recent past.We also outlined the outlook and direction of future research. 1 A brief introduction to the present issue The Qinghai–Tibet Plateau (QTP) is the highest and largest plateau in the world with an average elevation of more than 4000m. It started to uplift after the collision between India and Eurasia approximately 50 million years ago (Ma). However, all extensive uplifts occurred only after the early Miocene, between 30–23Ma, 15–7Ma, and 3.6–1.6Ma. The southern QTPmay have reached the current elevation earlier than

A central issue in the field of community genetics is the expectation that trait variation among genotypes play a defining role in structuring associated species and in forming com-munity phenotypes. Quantifying the existence of such community phenotypes in two com-mon garden environments also has important consequences for our understanding of gene-by-environment interactions at the community level. The existence of community phe-notypes has not been evaluated in the crowns of boreal forest trees. In this study we address the influence of tree genetics on needle chemistry and genetic x environment inter-actions on two gall-inducing adelgid aphids (Adelges spp. and Sacchiphantes spp.) that share the same elongating bud/shoot niche. We examine the hypothesis that the canopies of different genotypes of Norway spruce (Picea abies L.) support different community phe-notypes. Three patterns emerged. First, the two gallers show clear differences in their response to host genetics and environment. Whereas genetics significantly affected the abundance of Adelges spp. galls, Sacchiphantes spp. was predominately affected by the environment suggesting that the genetic influence is stronger in Adelges spp. Second, the
