Plant functional connectivity – integrating landscape structure and effective dispersal (2017, neutral): “This can leave them less resilient to environmental and demographic stochasticity and more likely to go extinct (Leimu et al. 2006; Vranckx et al. 2012).”
Genetic consequences of habitat fragmentation in plant populations: susceptible signals in plant traits and methodological approaches (2008, background): “Recently, two reviews have focused on the relationship between genetic diversity and population size (Leimu et al. 2006; Honnay & Jacquemyn 2007), one of the immediate possible demographic consequences of habitat fragmentation.”
Invasive plant species are locally adapted just as frequently and at least as strongly as native plant species (2016, background): “Second, in small populations, loss of genetic variability due to random genetic drift and exposure of accumulated deleterious alleles as a result of inbreeding can diminish the capacity to evolve adaptations (Leimu et al. 2006; Willi, van Buskirk & Hoffmann 2006; Bijlsma & Loeschcke 2012).”
The imbalance of nature: revisiting a Darwinian framework for invasion biology (2014, background): “In general, the correlation of population size and genetic diversity is a welltested tenet of conservation genetics (Leimu et al., 2006), and genetic variation is well recognized as a key driver of long-term adaptation.”
The rough edges of the conservation genetics paradigm for plants (2006, background): “Several reviews have compiled and evaluated the empirical evidence for the importance of genetic effects (e.g. Young et al. 1996; Booy et al. 2000), including the very recent review by Leimu et al. (2006).”
Tree invasions: a comparative test of the dominant hypotheses and functional traits (2011, methodology): “Moreover, in order to avoid pseudo-replication, effect sizes in a publication were pooled per species and per hypothesis tested, and we thus used the pooled mean effect size and the mean variance (Leimu et al. 2006; van Kleunen et al. 2010).”
Genetic factors in threatened species recovery plans on three continents (2016, background): “Fitness- related parameters, such as inbreeding and hybridization, can be directly related to population viability (Spielman et al. 2004; Leimu et al. 2006).”
Meta-analysis and the science of research synthesis (2018, positive): “…correlations between measures of genetic diversity, fitness and population size, that have demonstrated that reduction in population size due to habitat fragmentation reduces genetic variation, and that these losses of genetic diversity have a negative impact on fitness in affected populations 44 .”
How successful are plant species reintroductions (2011, background): “In their review, Leimu et al. (2006) found a positive association between mean genetic diversity and fitness in self-incompatible but not in self-compatible species, which may be the result of a greater susceptibility to small population size in the former than in the latter (Picó and van…”
Deep reefs are climatic refugia for genetic diversity of marine forests (2016, neutral): “Where ranges contracted or unfavourable niche conditions prevailed, diversity might be presently reduced due to bottlenecks, drift and/or reduced gene ﬂow (Young et al. , 1996; Leimu et al. , 2006).”
Can a seed bank maintain the genetic variation in the above ground plant population (2008, background): “…a species mating system, with outcrossing species being much more susceptible for loss of genetic diversity than self-compatible or selfing species (Leimu et al. 2006, Honnay and Jacquemyn 2007), we repeated this analysis using only obligate outcrossing and mainly outcrossing plant species (data…”
Ecological consequences of genetic diversity. (2008, background): “This work, initially sparked by observations of low genetic variation in high-profile species such as the cheetah, often focuses on relationships between population size, genetic diversity and fitness (e.g. Leimu et al. 2006).”
The Evolutionary Maintenance of Sexual Reproduction: Evidence from the Ecological Distribution of Asexual Reproduction in Clonal Plants (2008, background): “Failure of sexual reproduction is common in small plant populations (Leimu et al. 2006).”
