Longitudinal data set of a nationally representative sample of the population aged 65 and over in Japan, comparable to that collected in the US and other countries. The first two waves of data are now available to the international research community. The sample is refreshed with younger members at each wave so it remains representative of the population at each wave. The study was designed primarily to investigate health status of the Japanese elderly and changes in health status over time. An additional aim is to investigate the impact of long-term care insurance system on the use of services by the Japanese elderly and to investigate the relationship between co-residence and the use of long term care. While the focus of the survey is health and health service utilization, other topics relevant to the aging experience are included such as intergenerational exchange, living arrangements, caregiving, and labor force participation. The initial questionnaire was designed to be comparable to the (US) Longitudinal Study of Aging II (LSOAII), and to the Asset and Health Dynamics Among the Oldest Old (AHEAD, a pre-1924 birth cohort) sample of the Health and Retirement Study (HRS), which has now been merged with the HRS. The sample was selected using a multistage stratified sampling method to generate 340 primary sampling units (PSUs). The sample of individuals was selected for the most part by using the National Residents Registry System, considered to be universal and accurate because it is a legal requirement to report any move to local authorities within two weeks. From each of the 340 PSUs, 6-11 persons aged 65-74 were selected and 8-12 persons aged 75+ were sampled. The population 75+ was oversampled by a factor of 2. Weights have been developed for respondents to the first wave of the survey to reflect sampling probabilities. Weights for the second wave are under development. With these weights, the sample should be representative of the 65+ Japanese population. In fall 1999, 4,997 respondents aged 65+ were interviewed, 74.6 percent of the initial target. Twelve percent of responses were provided by proxies, because of physical or mental health problems. The second wave of data was collected in November 2001. The third wave was collected in November 2003. Questionnaire topics include family structure, and living arrangements; subjects'''' parents/spouse''''s parents/children; socioeconomic status; intergenerational exchange; health behaviors, chronic conditions, physical functioning; activities of daily living and instrumental activities of daily living; functioning in the community; mental health depression measures; vision and hearing; dental health; health care and other service utilization. A CD is available which include the codebook and data files for the first and second waves of the national sample. The third wave of data will be released at a later date. * Dates of Study: 1999-2003 * Study Features: Longitudinal, International * Sample Size: ** 4,997 Nov/Dec 1999 Wave 1 ** 3,992 Nov 2001 Wave 2 ** Nov 2003 Wave 3 Link: * ICPSR: http://www.icpsr.umich.edu/icpsrweb/ICPSR/studies/00156

A suite of plant traits is thought to make weed populations highly invasive, including vigorous growth and reproduction, superior competitive ability, and high dispersal ability. Using a breeding design and a common garden experiment, we tested whether such an “invasion syndrome” has evolved in an invasive range of Solidago altissima, and whether the evolution is likely to be genetically constrained. We found an overall shift in invasive phenotypes between native North American and invasive Japanese populations. The invasive populations were taller and produced more leaves, suggesting a superior ability to exploit limited resources. The populations also produced more allelopathic compounds that can suppress competitor growth. Finally, invasive populations produced more seeds, which are smaller and are released from a greater height, indicating a potential for superior dispersal ability than the native populations. Quantitative genetics analyses found a large amount of additive genetic variation in most focal traits across native and invasive populations, with no systematic differences in its magnitude between the ranges. Genetic covariances among three traits representing invasion strategies (leaf mass, polyacetylene concentration and seed size) were small. The R metric, which measures the effect of genetic covariances on the rate of adaptation, indicated that the covariance neither constrains nor accelerates concerted evolution of these traits. The results suggest that the invasion syndrome in S. altissima has evolved in the novel range due to ample additive genetic variation, and relatively free from genetic trade-offs.
Methods
Study system
The tall goldenrod, Solidago altissima L. (Asteraceae), is a perennial forb native to eastern North America (Werner et al., 1980) and is a dominant species of old fields and disturbed habitats. Solidago altissima was first introduced into Japan in the late 1890s as an ornamental plant but only became widespread across the country since the 1980s (Fukuda, 1982). Current molecular data suggests that invasive Japanese S. altissima populations are likely to be introduced primarily from south-eastern North America (Sakata et al., 2015), which may overlap with the distribution of a putative S. altissima variety, pluricephala that has also invaded other parts of Asia (Semple et al., 2015). The Japanese populations seem to be founded by multiple introduction events, resulting in similar levels of genetic diversity within a population at neutral markers as in the native populations (Sakata et al., 2015; Uesugi et al., 2020). Moreover, broad-sense genetic variation for herbivore resistance traits did not differ between the US and Japanese populations (Sakata et al., 2020), suggesting that evolution in introduced Japanese populations may not be genetically constrained. However, additive genetic variation and covariation among traits associated with competitive and dispersal abilities has not been examined previously.
In its native range, a diverse group of specialist and generalist herbivores keeps the S. altissima populations in check (Root, 1996), whereas in the invaded Japanese range, the plant generally escapes herbivory, except from Uroleucon nigrotuberculatum (a Solidago specialist aphid introduced in 1990’s, Cappuccino, 1987; Sugimoto & Matsumoto, 2000) and Corythucha marmorata (an Asteraceae specialist lacebug introduced to Japan in 2000, Kato & Ohbayashi, 2009; Sakata et al., 2014). Upon establishment in a field patch, S. altissima can rapidly grow tall and shade out neighbouring plants (Root, 1996), while suppressing germination and growth of competitor plants through allelopathy (Kobayashi et al., 2008; Johnson et al., 2010; Uesugi et al., 2019). It produces several compounds of polyacetylenes in roots, which are released into the soil at a concentration known to inhibit the growth of several other plant species (Kobayashi et al., 2008; Johnson et al., 2010; Uesugi & Kessler, 2013; Uesugi et al., 2019). Within a patch, S. altissima primarily spreads through rhizome production (Hartnett & Bazzaz, 1983), but colonization of new patch relies on wind-born seeds that are produced in abundance (Uesugi et al., 2020).
Experimental design
Seed sources and quantitative genetic breeding design:
Seeds were collected in 2016 from three native populations in the south-eastern United States within the known range of S. altissima var. pluricephala where invasive Japanese populations are likely to have originated (Durham, NC, Spartanburg, SC, and Murrells Inlet, SC; Sakata et al., 2015, Suppl. Table 1). Three invasive populations in Japan were sampled across a similar latitudinal range (Utsunomiya, Shizuoka, and Otsu). A principal component analysis (PCA) of variation in 19 WorldClim climatic variables among sampled populations indicated that invasive Japanese populations generally experience wetter summers and drier winters than native US populations (PC1, explaining 52.9 % of variance). Within each range, our study populations varied across a temperature gradient (PC2, explaining 35.5% of variance), with both ranges spanning similar PC2 coordinates (Suppl. Fig. 1, Suppl. Table 1 & 2).
Within each population, we collected seeds from ~50 maternal plants, which grew at least 10 m apart in the field to minimize the probability of sampling the same genetic individual multiple times. We germinated ~10 seeds per maternal plant in a common greenhouse environment (temperature at 18-30 °C and relative humidity at 60%) at Monash University, Victoria, Australia, and grew a single individual per maternal family in 12-cm pots with potting mix with Osmocote. Each population resulted in 18-35 parental (P1) individuals (Suppl. Table 1).
P1 individuals from each population were split into groups of five individuals (4-7 replicated groups per population) and crossed within a group using a partial diallel design with reciprocals but no selfing (Lynch & Walsh, 1998). Prior to the anthesis, we bagged branches of inflorescence (~ 5cm long) with nylon bags to avoid accidental pollen transfer. When > 50 % of the flowers on a branch had opened, we removed the branch of the sire plant, and rubbed it against an intact branch on a dam plant. Each plant sired four other individuals within the group and received pollen from the four. We also made a self-pollination cross as a negative control (because S. altissima is a self-incompatible species, self-crosses did not produce any viable seeds). This resulted in total of 760 crosses (20 crosses per group x 38 groups) across the populations.
Common garden experiment:
In 2017, three viable achenes from each cross were selected, and photographed under a dissecting scope for later examination of achene size (see “Seed dispersal ability” below). Seeds of the F1 generation were germinated as above, and two seedlings per cross were transplanted to individual 10-cm diameter pots. A lack of germination from some crosses resulted in a total of 1324 experimental individuals. Potted plants were placed in evenly spaced trays of 17 pots, across six benches (“blocks”) in the greenhouse as above. Trays were rotated weekly to mitigate effects of microclimate within the greenhouse until flowering.
Trait measurements
We measured 10 traits that are thought to mediate plant invasiveness, including growth rate, maximum stem height, specific leaf area (SLA), leaf mass, rhizome mass, inflorescence mass, days to first flower, flowering duration, root polyacetylene concentration, and seed size.
Growth, morphology, and phenology:
We estimated the relative growth rate of individual plants by measuring height on week 8 and week 10 after transplanting, which corresponded with the period of rapid vertical growth. Relative growth rate was determined as ([height at week 10 – week 8]/14 days). In week 15, we collected three fully expanded leaves from each plant at the height of 60 cm above the base. Each set of three leaves was scanned together, dried for 48 hours at 50 °C and weighed. Leaf area was measured using ImageJ (version 1.51), and specific leaf area (SLA) was calculated as [fresh leaf area/dry mass].
To estimate flower onset and flowering duration, we checked plants daily during the flowering period (week 14 through 22) and marked the dates we observed the first flower and the last senesced flower. Flowering duration for each plant was calculated as days from flowering onset to final day of flowering. We harvested plant biomass between weeks 22 and 25 as individual plants finished flowering. Aboveground biomass was separately harvested for leaves, stems, inflorescence, and ramets. We used inflorescence mass as a proxy for seed production (Root, 1996). We were unable to directly estimate seed production because S. altissima is an insect-pollinated, self-incompatible species, and does not naturally set seeds in the greenhouse. Belowground rhizomes were harvested by removing roots and washed in water. All harvested samples were dried for 48 hours at 50 °C before weighing.
Polyacetylene analysis:
Root samples were collected for polyacetylene analysis in week 15 by removing a subsample of root tissues from each plant. Root samples were flash frozen in liquid nitrogen and stored in -80 °C for later analysis. Following Uesugi et al. (2019), approximately 200 mg fresh weight of root tissue per sample was crushed with mortar and pestle in liquid nitrogen, sonicated in extraction buffer (1ml of 90% methanol) for 6 min, and left in the dark at room temperature for 24h. Samples were centrifuged, and 0.5 ml aliquot was filtered with 0.45 mm syringe filter. The samples were analysed with high-performance liquid chromatography (HPLC) at Monash University using Agilent Infinity 1260 equipped with C18 reserve-phase column (ED-C18, 2.7μm, 150×3.0mm). The elution method was: 0–5min, 0–20% of acetonitrile; 5–25min, 20–95% of acetonitrile and 25–30min, 95% of acetonitrile,
