Abstract Genetic monitoring of populations currently attracts interest in the context Convention on Biological Diversity but needs long-term planning and investments. However, genetic diversity has been largely neglected biodiversity monitoring, when addressed, it is treated separately, detached from other conservation issues, such as habitat alteration due to climate change. We report an accounting efforts monitor population Europe (genetic effort, GME), evaluation which can help guide...
Summary Small and isolated populations of species are susceptible to loss genetic diversity, owing random drift inbreeding. This diversity may reduce the evolutionary potential adapt changing environments, cause immediate fitness (cf. inbreeding depression). Together with other population size‐dependent stochastic processes, this lead increased probabilities extinction. set processes theories forms core conservation genetics has developed into paradigm. Many empirical studies have...
• The effects of increasing ammonium concentrations in combination with different pH levels were studied on five heathland plant species to determine whether their occurrence and decline could be attributed toxicity and/or levels. Plants grown growth media amended four (10, 100, 500 1000 µmol l−1) two resembling acidified (pH 3.5 or 4) weakly buffered 5 5.5) situations. Survival Antennaria dioica Succisa pratensis was reduced by low high concentrations. Biomass decreased increased decreasing...
Summary We studied the performance of 17 Dutch populations perennial Succisa pratensis , in relation to population size, genetic variation and habitat quality. used a path‐analytical model analyse possible relationships between these variables performance. Plants smaller produced fewer seeds per flower head. Their had lower germination rates higher seedling mortality, more were dormant or non‐viable. Population size was also correlated with measures. Small inbreeding coefficients than large...
Atmospheric nitrogen (N) deposition has been identified as a major threat to biodiversity, but field surveys of its effects have rarely focussed on sites which are actively managed maintain characteristic species. We analysed permanent quadrat data from 106 plots in nature reserves calcareous grassland the United Kingdom collected during survey between 1990 and 1993 compared with results resurvey 48 these 2006 2009. N showed no significant spatial association species richness, diversity, or...
Inbreeding depression (i.e. negative fitness effects of inbreeding) is central in evolutionary biology, affecting numerous aspects population dynamics and demography, such as the evolution mating systems, dispersal behaviour genetics quantitative traits. commonly observed animals plants. Here, we demonstrate that, addition to genetic processes, epigenetic processes may play an important role causing inbreeding effects. We compared markers outbred inbred offspring perennial plant Scabiosa...
Abstract Questions Has plant species richness in semi‐natural grasslands changed over recent decades? Do the temporal trends of habitat specialists differ from those generalists? there been a homogenization grassland vegetation? Location Different regions Germany and UK. Methods We conducted formal meta‐analysis re‐survey vegetation studies grasslands. In total, 23 data sets were compiled, spanning up to 75 years between surveys, including 13 wet grasslands, six dry four other types. Edaphic...
Abstract Conservation genetics is expanding its research horizon with a genomic approach, by incorporating the modern techniques of next‐generation sequencing (NGS). Application NGS overcomes many limitations conservation genetics. First, allows for genome‐wide screening markers, which may lead to more representative estimation genetic variation within and between populations. Second, distinction neutral non‐neutral markers. By populations on thousands single nucleotide polymorphism signals...
Plant phenotypes can be affected by environments experienced their parents. Parental environmental effects are reported for the first offspring generation and some studies showed persisting in second further generations. However, expression of these transgenerational proved context-dependent reproducibility low. Here we study context-dependency evaluating parental under a range induction evaluation conditions. We systematically evaluated two factors that influence effects: single- versus...
Widely distributed species, such as the perennial plant Arabidopsis lyrata, face a range of environmental conditions across space, creating selective pressures for local evolutionary adaptation. The species' fragmented distribution may reduce gene flow, which could either or increase adaptive potential. substantial variation in phenotypic traits observed this northwestern European reflect combination plastic responses to conditions, adaptation and nonadaptive genetic differentiation. We...
Summary Transgenerational environmental effects can trigger strong phenotypic variation. However, it is unclear how cues from different preceding generations interact. Also, little known about the genetic variation for these life history traits. Here, we present of grandparental and parental mild heat, their combination, on four traits third‐generation phenotype 14 Arabidopsis thaliana genotypes. We tested correlations with climate constructed a conceptual model to identify conditions that...
Abstract In long‐term grassland experiments, positive biodiversity effects on plant productivity commonly increase with time. Subsequent glasshouse experiments showed that these strengthened persist not only in the local environment but also when plants are transferred into a common environment. Thus, we hypothesized community diversity had acted as selective agent, resulting emergence of monoculture and mixture types differing genetic composition. To test our hypothesis, grew offspring from...
Background: In the seasonal tropics, fire generally occurs in dry season. Consequently, effects of and season drought on seedling establishment different tree functional types are correlated. Therefore, factors that more important for recruitment forest-savanna ecotones still poorly understood. Methods: We studied success seven tropical species (of forest transition origins) a common garden experiment using combinations (irrigation vs no-irrigation) (burning no-burning). Results: found...
Range margins are spatially complex, with environmental, genetic and phenotypic variations occurring across a range of spatial scales. We examine variation in temperature, genes metabolomic profiles within between populations the subalpine perennial plant Arabidopsis lyrata ssp. petraea from its northwest European range. Our surveys cover gradient fragmentation largely continuous Iceland, through more fragmented Scandinavian populations, to increasingly widely scattered at margin Scotland,...
Several reduced-representation bisulfite sequencing methods have been developed in recent years to determine cytosine methylation de novo nonmodel species. Here, we present epiGBS2, a laboratory protocol based on epiGBS with revised and user-friendly bioinformatics pipeline for wide range of species or without reference genome. epiGBS2 is cost- time-efficient the computational workflow designed reproducible manner. The library allows flexible choice restriction enzymes double digest. was...
Environmentally induced DNA methylation variants may mediate gene expression responses to environmental changes. If such are transgenerationally stable, there is potential for persist over multiple generations. Our current knowledge in plants, however, almost exclusively based on studies conducted sexually reproducing species where the majority of changes subject resetting germlines, limiting transgenerational epigenetics stress memory. Asexual reproduction circumvents and therefore be more...
Abstract: Plant biodiversity has declined seriously because of both habitat deterioration and fragmentation. As a result, many species have been forced into small, fragmented, isolated populations are believed to suffer from higher extinction risks. Genetic reinforcement the establishment new now widely used prevent extinction. However, genetic background transplants may affect long‐term success these increased variation reduce risk inbreeding or lead better performance by restored...
