Takagi E. Colonization success of a tree-killing bark beetle: Geographic variation and mismatch with host preference. Ecol Evol 2023; 13:e10274. [PMID: 37424940 PMCID: PMC10322651 DOI: 10.1002/ece3.10274] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2023] [Revised: 06/18/2023] [Accepted: 06/26/2023] [Indexed: 07/11/2023] Open
Abstract
The preference-performance hypothesis (PPH) predicts that female insects maximize their fitness by ovipositing on hosts where their offspring perform the best. The preference-performance relationships in bark beetles are complex because before offspring development can occur in the phloem, adult bark beetles must first successfully invade host trees, and then construct galleries beneath the bark. Therefore, a positive correlation between host preference and successful colonization is necessary for the PPH in bark beetles to hold (i.e., the preference-colonization hypothesis in bark beetles). In this study, through field choice experiments, I investigated the successful colonization of the bark beetle, Polygraphus proximus, within four allopatrically distributed Abies species across a distinct biogeographic boundary in Japan. The results of this study showed that the biogeographic boundary did not limit the successful colonization by P. proximus. I observed that successful colonization was low in A. firma, despite it being an exotic species in the study sites and the most preferred at the study sites, indicating a mismatch between preference and colonization success. Additionally, I observed that A. sachalinensis had a high colonization success rate, even though it was the least preferred species at the study sites.

Abstract
Abies ernestii var. salouenensis (Bordères & Gaussen) W. C. Cheng & L. K. Fu is endemic to southwest China, including the southeastern Tibetan Plateau and the northwestern Yunnan Province. The taxonomic relationships between A. ernestii var. salouenensis and two other closely related fir species (A. chensiensis Tiegh. and A. ernestii Rehd.) still need to be determined. Here, we report for the first time the whole chloroplast genome of A. ernestii var. salouenensis. Its genome is 121,759 bp long and is characterized by a circular structure with 68 peptide-encoding genes, 16 tRNAs, six ORFs, and four rRNAs. We also identified 70 microsatellite repeat sequences and 14 tandem repeat sequences in the chloroplast genome of A. ernestii var. salouenensis. Comparative genome analysis indicated considerable variation in ycf1 and ycf2. Phylogenetic analysis supported the monophyly of A. ernestii var. salouenensis, A. chensiensis Tiegh., and A. ernestii Rehd. The relationships among them should be surveyed using more samples at the species level. This study will facilitate taxonomic studies and the development of suitable chloroplast markers for fir species.

Abstract
Abies ernestii Rehder is endemic to the montane regions of Southwest China. Till now, phylogenetic relationships between A. ernestii and other closely related species remain unclear. In this study, we first characterized the complete chloroplast (cp) genome of A. ernestii. The whole cp genome was 121,841 bp in size, including one hundred and thirteen genes. Results of comparative cp genome revealed that only ycf1 and ycf2 was characterized by a considerable variation. Our phylogenetic analyses supported the monophyly of the genus Abies and revealed a clear separation between A. ernestii and A. chensiensis Tiegh. This study highlights the significance of using cp genomes to examine species boundaries among closely related fir species.

Abstract
BACKGROUND AND AIMS The biogeographic patterns of the East-Asia-endemic shrub Magnolia sieboldii, in which the range of the subsp. sieboldii is interposed with the disjunct distribution of subsp. japonica, implies a complex evolutionary history, involving rapid speciation and hybridization. Here, we aim to reveal the evolutionary and phylogeographic histories of the species with a particular focus on the time of subspecies divergence, the hypothesis of secondary hybridization and the Pleistocene survival of each subspecies, using a combination of genetic analyses and ecological niche modelling. METHODS Genetic variation, genetic structures and phylogenetic relationships were elucidated based on nuclear low-copy genes, chloroplast DNA, and nuclear simple sequence repeats (SSRs). A scenario selection analysis and divergence time estimation were performed using coalescent simulation in DIYABC and *BEAST. Ecological niche modelling and a test of niche differentiation were performed using Maxent and ENMTools. KEY RESULTS All marker types showed deep, but pronouncedly incongruent, west-east genetic divergences, with the subspecies being delineated only by the nuclear low-copy genes. Phylogenetic tree topologies suggested that ancient hybridization and introgression were likely to have occurred; however, this scenario did not receive significant support in the DIYABC analysis. The subspecies differentiated their niches, but both showed a dependence on high humidity and were predicted to have persisted during the last glacial cycle by maintaining a stable latitudinal distribution via migration to lower altitudes. CONCLUSIONS We found a deep genetic divergence and a pronounced phylogenetic incongruence among the two subspecies of M. sieboldii, which may have been driven by major paleogeographic and paleoclimatic events that have occurred since the Neogene in East Asia, including global cooling, climate oscillations and the formation of land bridges. Both subspecies were, however, considered to persist in situ in stable climatic conditions during the late Pleistocene.

Abstract
BACKGROUND AND AIMS Inferring the evolutionary relationships of species and their boundaries is critical in order to understand patterns of diversification and their historical drivers. Despite Abies (Pinaceae) being the second most diverse group of conifers, the evolutionary history of Circum-Mediterranean firs (CMFs) remains under debate. METHODS We used restriction site-associated DNA sequencing (RAD-seq) on all proposed CMF taxa to investigate their phylogenetic relationships and taxonomic status. KEY RESULTS Based on thousands of genome-wide single nucleotide polymorphisms (SNPs), we present here the first formal test of species delimitation, and the first fully resolved, complete species tree for CMFs. We discovered that all previously recognized taxa in the Mediterranean should be treated as independent species, with the exception of Abies tazaotana and Abies marocana. An unexpectedly early pulse of speciation in the Oligocene-Miocene boundary is here documented for the group, pre-dating previous hypotheses by millions of years, revealing a complex evolutionary history encompassing both ancient and recent gene flow between distant lineages. CONCLUSIONS Our phylogenomic results contribute to shed light on conifers' diversification. Our efforts to resolve the CMF phylogenetic relationships help refine their taxonomy and our knowledge of their evolution.

Abstract
Research Highlights: We detected the longitudinal gradients of genetic diversity parameters, such as the number of alleles, effective number of alleles, heterozygosity, and inbreeding coefficient, and found that these might be attributable to climatic conditions, such as temperature and snow depth. Background and Objectives: Genetic diversity among local populations of a plant species at its distributional margin has long been of interest in ecological genetics. Populations at the distribution center grow well in favorable conditions, but those at the range margins are exposed to unfavorable environments, and the environmental conditions at establishment sites might reflect the genetic diversity of local populations. This is known as the central-marginal hypothesis in which marginal populations show lower genetic variation and higher differentiation than in central populations. In addition, genetic variation in a local population is influenced by phylogenetic constraints and the population history of selection under environmental constraints. In this study, we investigated this hypothesis in relation to Abies sachalinensis, a major conifer species in Hokkaido. Materials and Methods: A total of 1189 trees from 25 natural populations were analyzed using 19 EST-SSR loci. Results: The eastern populations, namely, those in the species distribution center, showed greater genetic diversity than did the western peripheral populations. Another important finding is that the southwestern marginal populations were genetically differentiated from the other populations. Conclusions: These differences might be due to genetic drift in the small and isolated populations at the range margin. Therefore, our results indicated that the central-marginal hypothesis held true for the southernmost A. sachalinensis populations in Hokkaido.

Abstract
The nucleotide sequence of the chloroplast genome from Abies koreana is the first to have complete genome sequence from genus Abies of family Pinaceae. The circular double-stranded DNA, which consists of 121,373 base pairs (bp), contains a pair of very short inverted repeat regions (IRa and IRb) of 264 bp each, which are separated by a small and large single-copy regions (SSC and LSC) of 54,197 and 66,648 bp, respectively. The genome contents of 114 genes (68 peptide-encoding genes, 35 tRNA genes, four rRNA genes, six open reading frames and one pseudogene) are similar to the chloroplast DNA of other species of Abietoideae. Loss of ndh genes was also identified in the genome of A. koreana like other genomes in the family Pinaceae. Thirteen genes contain one (11 genes) or two (rps12 and ycf3 genes) introns. In phylogenetic analysis, the tree confirms that Abies, Keteleeria and Cedrus are strongly supported as monophyletic. Other inverted repeat sequences located in 42-kb inversion points (1186 bp) include trnS-psaM-ycf12- ψtrnG genes.

Abstract
Abies alba and Abies pinsapo are closely related species with the same ribulose 1·5-bisphosphate carboxylase/oxygenase (Rubisco) large subunit (rbcL) but contrasting hydraulic traits and mesophyll structure occurring in the Iberian Peninsula under contrasting conditions. As photosynthesis and hydraulic capacities often co-scale, we hypothesize that these species differ in mesophyll conductance to CO(2) (g(m) ). g(m) and key anatomical traits were measured in both species. Drought-adapted population of A. pinsapo has higher photosynthesis than the more mesic population of A. alba, in agreement with its higher hydraulic capacity. However, A. alba exhibits the largest stomatal conductance (g(s) ), and so water use efficiency (WUE) is much higher in A. pinsapo. The differences in photosynthesis were explained by differences in g(m) , indicating a correlation between hydraulic capacity and g(m) . We report a case where g(m) is the main factor limiting photosynthesis in one species (A. alba) when compared with the other one (A. pinsapo). The results also highlight the discrepancy between g(m) estimates based on anatomical measurements and those based on gas exchange methods, probably due to the very large resistance exerted by cell walls and the stroma in both species. Thus, the cell wall and chloroplast properties in relation to CO(2) diffusion constitute a near-future research priority.

Abstract
The family Pinaceae is made up mostly of diploid species (2n = 24). Systematization of karyotype analysis was developed to make comparison of intra- and interspecific karyotypes among the Pinaceae more accurate and reliable. Considering all parameters, the genera Pseudotsuga and Pseudolarix have the “most derived” (or advanced) and asymmetric karyotypes in the Pinaceae, followed by Larix, Picea, Abies, and Cedrus. The genus Pinus was the “least derived” (or ancestral) of all the genera of the Pinaceae analyzed. Differences in karyotype formulae and asymmetry indices were found among species within the same genera, suggesting that structural changes may have contributed to the diversification of the genus. This review is a detailed analysis of comparative karyotyping based on similar parameters, including numeric data and cytogenetic information. Telomeric sequence repeats and rDNA distribution in the Pinaceae were surveyed. The role of transposition in rDNA chromosome distribution is analyzed. Cytogenetic implications of hybridization between related species are reported. Likewise, the relationships between molecular phylogenetic and karyotype evolution is discussed in light of several reports. Within many genera, chromosomal organization was conserved despite independent molecular divergence and adaptation through the evolutionary history of the species of the Pinaceae.

Abstract
Abies alba and Abies pinsapo are two closely related fir species that occur in the Iberian Peninsula under very different environmental conditions. Abies alba proliferates in the humid European mountains, including the Spanish Pyrenees. In contrast, A. pinsapo is a relict species that occurs in some restricted areas of the Mediterranean mountain ranges in Spain and Morocco, which experience intense summer drought periods. To cope with the high atmospheric evaporative demand during summer, A. pinsapo may either have a high resistance to xylem cavitation or develop a very efficient conducting system to reduce the soil-to-leaf water potential gradient. To investigate such hypotheses, we measured (i) the xylem vulnerability to cavitation for different populations, and (ii) several anatomical and hydraulic parameters indicating xylem sufficiency for -supplying water to the shoot in two contrasting populations of both species. Our results show that the resistance to cavitation was not different between species or populations. However, hydraulic conductivity (K(h)), specific hydraulic conductivity (K(s)), leaf-specific conductivity (LSC) and whole-shoot hydraulic conductance (K(shoot)) were higher in A. pinsapo, indicating a higher efficiency of water transport, which should contribute to maintaining its xylem tension below the threshold for rapidly increasing cavitation. The higher K(s) in A. pinsapo was largely a result of its wider tracheids, suggesting that this species may be much more vulnerable to freeze-thaw-induced cavitation than A. alba. This is consistent with the absence of A. pinsapo in northern mountain ranges with cooler winters. These physiological differences could partly explain the niche segregation and the geographical separation of these two firs.

Abstract
Introgression has been considered to be one of main factors leading to phylogenetic incongruence among different datasets at lower taxonomic levels. In the plants of Pinaceae, the mtDNA, cpDNA, and nuclear DNA (nrDNA) may have different evolutionary histories through introgression because they are inherited maternally, paternally and biparentally, respectively. We compared mtDNA, cpDNA, and two low-copy nrDNA phylogenetic trees in the genus Pinus subgenus Strobus, in order to detect unknown past introgression events in this group. nrDNA trees were mostly congruent with the cpDNA tree, and supported the recent sectional and subsectional classification system. In contrast, mtDNA trees split the members of sect. Quinquefoliae into two groups that were not observed in the other gene trees. The factors constituting incongruence may be divided into the following two categories: the different splits within subsect. Strobus, and the non-monophyly of subsect. Gerardianae. The former was hypothesized to have been caused by the past introgression of cpDNA, mtDNA or both between Eurasian and North American species through Beringia. The latter was likely caused by the chimeric structure of the mtDNA sequence of P. bungeana, which might have originated through past hybridization, or through a horizontal transfer event and subsequent recombination.

Abstract
The reproductive isolation barriers and the mating patterns among Pinus pumila, P. parviflora var. pentaphylla and their hybrids were examined by flowering phenology and genetic assays of three life stages: airborne-pollen grains, adults and seeds, in a hybrid zone on Mount Apoi, Hokkaido, Japan. Chloroplast DNA composition of the airborne-pollen was determined by single-pollen polymerase chain reaction. Mating patterns were analysed by estimating the molecular hybrid index of the seed parent, their seed embryos and pollen parents. The observation of flowering phenology showed that the flowering of P. pumila precedes that of P. parviflora var. pentaphylla by about 6 to 10 days within the same altitudinal ranges. Although this prezygotic isolation barrier is effective, the genetic assay of airborne-pollen showed that the two pine species, particularly P. pumila, still have chances to form F(1) hybrid seeds. Both parental species showed a strong assortative mating pattern; F(1) seeds were found in only 1.4% of seeds from P. pumila mother trees and not at all in P. parviflora var. pentaphylla. The assortative mating was concluded as the combined result of flowering time differentiation and cross-incompatibility. In contrast to the parental species, hybrids were fertilized evenly by the two parental species and themselves. The breakdown of prezygotic barriers (intermediate flowering phenology) and cross-incompatibility may account for the unselective mating. It is suggested that introgression is ongoing on Mount Apoi through backcrossing between hybrids and parental species, despite strong isolation barriers between the parental species.

Abstract
Range-wide genetic variation of the widespread cold-temperate spruce Picea jezoensis was studied throughout northeast Asia using maternally inherited mitochondrial DNA and paternally inherited chloroplast DNA markers. This study assessed 33 natural populations including three varieties of the species in Japan, Russia, China, and South Korea. We depicted sharp suture zones in straits around Japan in the geographical distribution pattern of mitochondrial haplotypes (GST=0.901; NST=0.934). In contrast, we detected possible extensive pollen flow without seed flow across the straits around Japan during the past population history in the distribution pattern of chloroplast haplotypes (GST=0.233; NST=0.333). The analysis of isolation by distance of the species implied that by acting as a barrier for the movement of seeds and pollen, the sharp suture zones contributed considerably to the level of genetic differentiation between populations. Constructed networks of mitochondrial haplotypes allowed inference of the phylogeographical history of the species. We deduced that the disjunction with Kamchatka populations reflects range expansion and contraction to the north of the current distribution. Within Japan, we detected phylogeographically different types of P. jezoensis between Hokkaido and Honshu islands; P. jezoensis in Honshu Island may have colonized this region from the Asian continent via the Korean peninsula and the species in Hokkaido Island is likely to have spread from the Asian continent via Sakhalin through land bridges. Japanese endemism of mitochondrial haplotypes in Hokkaido and Honshu islands might have been promoted by separation of these islands from each other and from the Asian continent by the straits during the late Quaternary.

Abstract
Based on fossil pollen, the distribution range of Taiwan fir [Abies kawakamii (Hay.) Ito] (Pinaceae) is smaller than it was 50 000 years ago. To characterize the present refuge populations of A. kawakamii, which survive only in subalpine forests in Taiwan, we surveyed nuclear genes and chloroplast intergenic spacers to assess the genetic diversity of Taiwan fir. Populations maintain high genetic diversity and contain similar numbers of haplotypes for the GapC (cytosolic glyceraldehyde 3-phosphate dehydrogenase) fragment. Haplotypes for GapC are generally widespread, and population-specific haplotypes accounted for 2.5% of the total. Differentiation among populations is very low (G(ST) = 0.01). Only three haplotypes were detected for the cpDNA marker, and every population had one or two haplotypes. In a neutrality test, the variation in nucleotides did not deviate from that expected with neutral evolution for either marker. A retreat route to higher elevations was not evident from either the GapC or cpDNA markers. Hsuehshan was the site of the most divergent population in Taiwan. We concluded that uniform genetic diversity, low differentiation, low numbers of population-specific haplotypes, and neutral evolution characterize contemporary refuge populations of Taiwan fir.
