Triggers of tree mortality under drought

Nature, Vol. 558, No. 7711. (27 June 2018), pp. 531-539,


Severe droughts have caused widespread tree mortality across many forest biomes with profound effects on the function of ecosystems and carbon balance. Climate change is expected to intensify regional-scale droughts, focusing attention on the physiological basis of drought-induced tree mortality. Recent work has shown that catastrophic failure of the plant hydraulic system is a principal mechanism involved in extensive crown death and tree mortality during drought, but the multi-dimensional response of trees to desiccation is complex. Here we focus on the ...


Environmental and geographic variables are effective surrogates for genetic variation in conservation planning

Proceedings of the National Academy of Sciences, Vol. 114, No. 48. (28 November 2017), pp. 12755-12760,


[Significance] To protect biodiversity for the long term, nature reserves and other protected areas need to represent a broad range of different genetic types. However, genetic data are expensive and time-consuming to obtain. Here we show that freely available environmental and geographic variables can be used as effective surrogates for genetic data in conservation planning. This means that conservation planners can, with some confidence, design protected area systems to represent intraspecific genetic diversity without investing in expensive programs to obtain and analyze ...


General introduction and methodological overview

Hybrid incompatibility caused by an epiallele

Proceedings of the National Academy of Sciences, Vol. 114, No. 14. (04 April 2017), pp. 3702-3707,


[Significance] Deleterious mutations in different copies of a duplicated gene pair have the potential to cause hybrid incompatibility between diverging subpopulations, contributing to reproductive isolation and speciation. This study demonstrates a case of epigenetic gene silencing rather than pseudogene creation by mutation, contributing to a lethal gene combination on hybridization of two ecotypes of Arabidopsis thaliana. Our findings provide direct evidence that naturally occurring epigenetic variation can contribute to incompatible hybrid genotypes, reducing gene flow between subtypes of the same species. [Abstract] Hybrid incompatibility ...

Genetic divergence in forest trees: understanding the consequences of climate change

Functional Ecology, Vol. 28, No. 1. (February 2014), pp. 22-36,


[::] Predicted climate change is heading in many respects into untested environmental conditions for trees and to the reshuffling of species distributions. We explore the consequences that these changes are likely to have on population differentiation of adaptive traits. Superimposed on the spatial redistribution of the species, will there be a redistribution of their genetic variation? [::] We base our predictions on a conceptual framework, whose elements are the extant differentiation, and the predicted divergent evolution of populations along purposely chosen altitudinal/latitudinal ...


Intraspecific trait variation across scales: implications for understanding global change responses

Global Change Biology, Vol. 22, No. 1. (January 2016), pp. 137-150,


Recognition of the importance of intraspecific variation in ecological processes has been growing, but empirical studies and models of global change have only begun to address this issue in detail. This review discusses sources and patterns of intraspecific trait variation and their consequences for understanding how ecological processes and patterns will respond to global change. We examine how current ecological models and theories incorporate intraspecific variation, review existing data sources that could help parameterize models that account for intraspecific variation in ...


Multispecies coalescent delimits structure, not species

Proceedings of the National Academy of Sciences, Vol. 114, No. 7. (14 February 2017), pp. 1607-1612,


[Significance] Despite its widespread application to the species delimitation problem, our study demonstrates that what the multispecies coalescent actually delimits is structure. The current implementations of species delimitation under the multispecies coalescent do not provide any way for distinguishing between structure due to population-level processes and that due to species boundaries. The overinflation of species due to the misidentification of general genetic structure for species boundaries has profound implications for our understanding of the generation and dynamics of biodiversity, because any ecological ...


An Anthropocene map of genetic diversity

Science, Vol. 353, No. 6307. (29 September 2016), pp. 1532-1535,


The Anthropocene is witnessing a loss of biodiversity, with well-documented declines in the diversity of ecosystems and species. For intraspecific genetic diversity, however, we lack even basic knowledge on its global distribution. We georeferenced 92,801 mitochondrial sequences for >4500 species of terrestrial mammals and amphibians, and found that genetic diversity is 27% higher in the tropics than in nontropical regions. Overall, habitats that are more affected by humans hold less genetic diversity than wilder regions, although results for mammals are sensitive ...


Identifying refugia from climate change using coupled ecological and genetic data in a transitional Mediterranean-temperate tree species

Molecular Ecology, Vol. 22, No. 8. (April 2013), pp. 2128-2142,


Populations occurring in areas of overlap between the current and future distribution of a species are particularly important because they can represent “refugia from climate change”. We coupled ecological and range-wide genetic variation data to detect such areas and to evaluate the impacts of habitat suitability changes on the genetic diversity of the transitional Mediterranean-temperate tree Fraxinus angustifolia. We sampled and genotyped 38 natural populations comprising 1006 individuals from across Europe. We found the highest genetic diversity in western and northern ...


The state of the world's forest genetic resources



[Excerpt: Executive summary] Forests and trees enhance and protect landscapes, ecosystems and production systems. They provide goods and services which are essential to the survival and well-being of all humanity. Forest genetic resources (FGR) are the heritable materials maintained within and among tree and other woody plant species that are of actual or potential economic, environmental, scientific or societal value. FGR are essential for the adaptation and evolutionary processes of forests and trees as well as for improving their productivity. [\n] The world’s current population of 7.2 billion ...


Community genetics: resource addition has opposing effects on genetic and species diversity in a 150-year experiment

Ecology Letters, Vol. 12, No. 2. (February 2009), pp. 165-170,


We used the Park Grass Experiment, begun in 1856, to test alternative hypotheses about the relationship between genetic diversity and plant species diversity. The niche variation hypothesis predicts that populations with few interspecific competitors and hence broader niches are expected to contain greater genetic diversity. The coexistence hypothesis predicts that genetic diversity within species favours coexistence among species and therefore species and genetic diversity should be positively correlated. Amplified Fragment Length Polymorphism (AFLP) markers were used to measure the genetic diversity ...

This paper presents the results of our seventh annual horizon scan, in which we aimed to identify issues that could have substantial effects on global biological diversity in the future, but are not currently widely well known or understood within the conservation community. Fifteen issues were identified by a team that included researchers, practitioners, professional horizon scanners, and journalists. The topics include use of managed bees as transporters of biological control agents, artificial superintelligence, electric pulse trawling, testosterone in the aquatic ...


The return of the variance: intraspecific variability in community ecology

Trends in Ecology & Evolution, Vol. 27, No. 4. (1 April 2012), pp. 244-252,


Despite being recognized as a promoter of diversity and a condition for local coexistence decades ago, the importance of intraspecific variance has been neglected over time in community ecology. Recently, there has been a new emphasis on intraspecific variability. Indeed, recent developments in trait-based community ecology have underlined the need to integrate variation at both the intraspecific as well as interspecific level. We introduce new T-statistics (T for trait), based on the comparison of intraspecific and interspecific variances of functional traits ...


Why intraspecific trait variation matters in community ecology

Trends in Ecology & Evolution, Vol. 26, No. 4. (01 April 2011), pp. 183-192,


Natural populations consist of phenotypically diverse individuals that exhibit variation in their demographic parameters and intra- and inter-specific interactions. Recent experimental work indicates that such variation can have significant ecological effects. However, ecological models typically disregard this variation and focus instead on trait means and total population density. Under what situations is this simplification appropriate? Why might intraspecific variation alter ecological dynamics? In this review we synthesize recent theory and identify six general mechanisms by which trait variation changes the outcome ...

Breeding technologies to increase crop production in a changing world

Science, Vol. 327, No. 5967. (2010), pp. 818-822,


To feed the several billion people living on this planet, the production of high-quality food must increase with reduced inputs, but this accomplishment will be particularly challenging in the face of global environmental change. Plant breeders need to focus on traits with the greatest potential to increase yield. Hence, new technologies must be developed to accelerate breeding through improving genotyping and phenotyping methods and by increasing the available genetic diversity in breeding germplasm. The most gain will come from delivering these ...

Conserving genetic resources on-site in forest ecosystems

Forest Ecology and Management, Vol. 35, No. 1-2. (June 1990), pp. 45-68,


Genetic diversity and its structure (its organization in space and time) are the critical raw materials from which many other aspects of diversity are derived. These genetic resources represent information about unique and successful relationships among genes and between gene complexes and environments. Only a fraction of this information has been mined through research. The balance, and the genetic materials themselves, are most effectively conserved for future use by on-site (in-situ) preservation, management, or restoration of populations, communities and entire landscapes. ...

Genetic structure of natural populations of black locust (Robinia pseudoacacia L.) at Coweeta, North Carolina

Journal of Plant Research In Journal of Plant Research, Vol. 111, No. 1. (1998), pp. 17-24,


Natural population of black locust maintains very high levels of genetic diversity within populations without any noticeable geographic patterns. In order to assess the species' potential for manipulation through breeding programs, more detailed spatial pattern analyses of fine-scale population structure was attempted in the two study sites (watershed 2 and 21) in the Coweeta River Basin of southern Appalachian mountains using allozyme markers. Of the 200 and 420 plants examined in watershed 21 and 2 respectively, 13 and 15 major genotypes ...


Isolation and characterization of microsatellite loci in Sorbus aria (Rosaceae)

In Conservation Genetics Resources, Vol. 2, No. 1. (2010), pp. 341-343,


Sorbus aria (L) Crantz (Common Whitebeam) is native to Europe, east of the Balkans and in North Africa; it is also present in the Canary Islands. To evaluate the genetic diversity in natural populations of this vulnerable species, nine novel polymorphic microsatellite markers were isolated from enriched libraries. Microsatellite loci were screened in 97 individuals from La Palma (Canary Islands) and Sierra Nevada (Granada, Spain). Examination of the microsatellite profiles shows that S. aria individuals have up to three alleles per ...


RAPD variation and population genetic structure in Prunus mahaleb (Rosaceae), an animal-dispersed tree

Molecular Ecology, Vol. 9, No. 9. (September 2000), pp. 1293-1305,


We examined the patterns of random amplified polymorphic DNA (RAPD) variation among seven Prunus mahaleb (Rosaceae) populations extending over ≈ 100 km2 to examine local differentiation in relation to spatial isolation due to both geographical distance and differences in elevation. No less than 51.4% of the RAPD loci were polymorphic, but very few were fixed and among-population variation accounted for 16.46% of variation in RAPD patterns. Mean gene diversity was 0.1441, with mean Nei’s genetic diversity for individual populations ranging between ...

Phylogeny of Elms (Ulmus, Ulmaceae): Molecular Evidence for a Sectional Classification

Systematic Botany, Vol. 19, No. 4. (1994), pp. 590-610


The approximately 45 woody species of Ulmus (Ulmaceae) have been placed in five to nine sections on the basis of morphological characters. Cladistic analyses of chloroplast DNA restriction site variation were employed to examine phylogenetic relationships among 29 Ulmus accessions, including representatives from all proposed sections and subsections, and Zelkova serrata. Sufficient variation was detected to construct cladograms with branches both well-resolved and supported. The cpDNA results are largely congruent with those based on nuclear ribosomal DNA. Inclusion of 18 morphological/chemical ...


The history of elm breeding

Investigación Agraria: Sistemas y Recursos Forestales, Vol. 13, No. 1. (2004), pp. 161-177


Breeding elms resistant to Dutch elm disease (DED) started in the Netherlands in the year 1928 on the initiative of a group of women scientists. They were active until 1954, when Hans Heybroek took over at the Dorschkamp Research Institute and carried on until his retirement in 1992. Two more programmes were initiated in Europe, in Italy and Spain, in 1978 and 1993 respectively, under the impulse of Dutch breeding activities. Elm breeding in America began in 1937 in the USDA-Agricultural ...


The phylogeography of Eurasian Fraxinus species reveals ancient transcontinental reticulation

Molecular Phylogenetics and Evolution, Vol. 77 (August 2014), pp. 223-237,


To investigate the biogeographical history of ashes species of the Eurasian section Fraxinus and to test the hypothesis of ancient reticulations, we sequenced nuclear DNA (nETS and nITS, 1075 bp) for 533 samples and scored AFLP for 63 samples of Eurasian ashes within the section Fraxinus. The nITS phylogeny retrieved the classical view of the evolution of the section, whereas nETS phylogeny indicated an unexpected separation of F. angustifolia in two paraphyletic groups, respectively found in southeastern Europe and in the other ...


Systematics of Fraxinus (Oleaceae) and evolution of dioecy

Plant Systematics and Evolution In Plant Systematics and Evolution, Vol. 273, No. 1-2. (2008), pp. 25-49,


Phylogenetic relationships among 40 of the 43 recognized species of Fraxinus L. (Oleaceae) were estimated on the basis of 106 nuclear ribosomal ITS sequences. ITS trees resulting from maximum likelihood (ML), maximum parsimony (MP) and Bayesian inference (BI) are congruent and identify six distinct lineages. These clades allow establishing sections with high molecular and morphological support. The basal resolution generally has low ML bootstrap and MP jackknife support, but the Bayesian posterior probabilities are high for certain relationships. An independent data ...


Population structure, gene diversity, and differentiation in natural populations of Cedar pines (Pinus subsect.Cembrae, Pinaceae) in the USSR

Plant Systematics and Evolution In Plant Systematics and Evolution, Vol. 182, No. 3-4. (1992), pp. 121-134,


Twelve natural populations of four cedar pine species,Pinus sibirica, P. cembra, P. pumila, andP. koraiensis, occurring in the Soviet Union were investigated by starch-gel electrophoresis. Frequencies of 55 alleles at 19 loci were determined. Interpopulation genetic diversity inP. sibirica andP. pumila was only 2–4 per cent of the total genetic diversity. Nei's distance coefficient (Dn) was used to estimate the level of genetic differentiation among conspecific populations and among species. Dn values among populations ranged from 0.006 to 0.038. A dendrogram ...
