“…First, the very low effective size of the Korean populations used in the ABC analysis distinguishes them from the other native populations and supports the singularity of the Korean sampling area. The Korean samples originated from a natural forest that was most likely dominated by nonhost species (e.g., conifers and oaks; Lee, Kang, & Park, ) for ALB (Sjöman et al, ). This might have influenced the population genetic structure of ALB by affecting spread and reproduction.…”

“…This blurred geographic genetic structure is uncommon for populations in their native ranges, whose structure is usually shaped by multiple factors that constrain gene flow, such as biogeography and natural barriers (Goldberg & Lande, 2007;Hewitt, 2000). In previous studies, this particular genetic structure has been considered to reflect human-mediated population translo- forest that was most likely dominated by nonhost species (e.g., conifers and oaks; Lee, Kang, & Park, 2004) for ALB (Sjöman et al, 2014).…”

Retracing introduction routes is crucial for understanding the evolutionary processes involved in an invasion, as well as for highlighting the invasion history of a species at the global scale. The Asian long‐horned beetle (ALB) Anoplophora glabripennis is a xylophagous pest native to Asia and invasive in North America and Europe. It is responsible for severe losses of urban trees, in both its native and invaded ranges. Based on historical and genetic data, several hypotheses have been formulated concerning its invasion history, including the possibility of multiple introductions from the native zone and secondary dispersal within the invaded areas, but none have been formally tested. In this study, we characterized the genetic structure of ALB in both its native and invaded ranges using microsatellites. In order to test different invasion scenarios, we used an approximate Bayesian “random forest” algorithm together with traditional population genetics approaches. The strong population differentiation observed in the native area was not geographically structured, suggesting complex migration events that were probably human‐mediated. Both native and invasive populations had low genetic diversity, but this characteristic did not prevent the success of the ALB invasions. Our results highlight the complexity of invasion pathways for insect pests. Specifically, our findings indicate that invasive species might be repeatedly introduced from their native range, and they emphasize the importance of multiple, human‐mediated introductions in successful invasions. Finally, our results demonstrate that invasive species can spread across continents following a bridgehead path, in which an invasive population may have acted as a source for another invasion.

“…Lenoir & Svenning, ), we investigated the peer‐reviewed literature on Larix range shifts under contemporary rapid climate change and found a total of 83 publications encompassing 181 observations of range limit dynamics across the distribution of Larix (see Appendix S2, Table A1). Due to extensive early 20th century alteration and degradation (Lee, Kang, & Park, ; Wang et al., ), and the limited areal extent (i.e., occurring on islands) of most forests of the East Asian archipelago (e.g., Sakhalin Oblast, Japan; Figure ), we restricted our survey to mainland studies and thereby omitted L. kaempferi and L. kamtschatica from the analysis. Contemporary rapid climate change is defined in this paper as the period from 1980 to present day.…”

Aim Recent and rapid warming is reorganizing terrestrial vegetation, creating novel species assemblages, and shifting range limits. Relative to the evergreen species that currently dominate much of the boreal forest landscape, Larix (larch) distributions may be particularly responsive to climatic change due to their deciduous habit, and quick growth and reproduction. Here, we amassed data from 83 studies to describe and explain observed patterns of Larix range shifts under contemporary climate change. Location Northern hemisphere. Taxon Species of the genus Larix, deciduous gymnosperms. Methods With 181 observations of Larix range limit dynamics, we used five distribution parameters (tree line advance, stand infilling, tree line recession, stand thinning, no response) and their determinants (climate, land use change, natural disturbance) to describe and explain observed patterns of Larix range shifts under contemporary climate change. We ran a redundancy analysis on the matrix of five distribution parameters considered with other climatic and nonclimatic parameters as explanatory variables. We also characterized the climatic niche of Larix species (temperature and precipitation) and how the niche has changed during the 20th century. Results Of 173 sites studied over the full distribution of Larix, 63% experienced Larix population increases, 18% had population decreases, and no response was detected at 19% of sites. Latitudinal Larix tree lines in Siberia and North America appear to be infilling and shifting their distributions northward, whereas Larix recession and thinning was more common in southern regions, suggesting southern populations may be experiencing greater drought stress than their northern counterparts. Climatic niches of most Larix species shifted towards warmer and wetter conditions, with tree line advance/forest infilling in cool/dry climate space, and recession/thinning in warm/dry space. Main conclusions Northern expansion is underway or seems imminent for boreal Larix species, primarily L. laricina in North America. Retraction in southern regions and disappearance of some mountainous populations may be inevitable due to their narrow ecological niches. Species restricted to mountainous habitats may expand locally, though will likely not contribute to broad scale range expansion. These changes will depend on suitable climate, disturbance, and dispersal mechanisms.

“…This tree has been one of the major species planted for reforestation, and is managed intensively throughout the country (Lee et al 2004). Although fertilizers have been used to increase annual tree growth (Joo et al 1983) and/or to determine the nutrient dynamics of litter (Lee and Son 2006;Park et al 2008), few attempts to synthetically and quantitatively examine the importance and behavior of carbon and nitrogen dynamics by litter fall inputs after fertilization in larch plantations have been undertaken (Lee and Son 2006).…”

This study was carried out to evaluate the effects of fertilization on carbon and nitrogen dynamics by litter fall of a 36-year-old larch (Larix leptolepis) plantation in the Sambong Exhibition Forests, Gyeongsangnam-do, Korea. Litter was collected monthly between April 2003 and May 2006. Seasonal inputs of litter fall components such as needle, broad leaf, branch, bark and total litter inputs followed a similar pattern between fertilized and unfertilized plots. The annual amounts of the litter components were not significantly different (P 4 0.05) between fertilized and unfertilized plots. Mean needle litter fall was similar between the fertilized (2564 kg ha 71 yr 71 ) and unfertilized plots (2501 kg ha 71 yr 71 ) and total annual litter fall averaged 3552 kg ha 71 yr 71 in the fertilized and 3541 kg ha 71 yr 71 in the unfertilized plots during the sampling period. Proportion of needle litter fall was slightly higher in the fertilized (72.2%) than in the unfertilized (70.8%) plots. Carbon concentrations of needle litter were not significantly affected by fertilization (P 4 0.05), while there was a significant fertilization effect on nitrogen concentrations with high nitrogen concentrations of needle litter in the fertilized (7.7 g kg 71 ) compared with the unfertilized (6.8 g kg 71 ) plots. There was no significant difference (P 4 0.05) in the organic carbon inputs by needle litter between the fertilized and unfertilized plots, whereas annual nitrogen inputs were significantly higher in the fertilized (17.7 kg N ha 71 yr 71 ) than in the unfertilized (15.6 kg N ha 71 yr 71 ) plots. The results indicated that nitrogen dynamics by litter fall could be affected by fertilization, but a minimal impact to carbon dynamics by litter fall in the larch plantation.
