Summary: Intraspecific genetic variation is crucial for wild populations, and evaluating genetic diversity patterns is essential for guiding conservation policies, especially for threatened species. A study on the critically endangered plant Mimosa catharinensis using SNP markers revealed moderate genetic diversity levels, high outcrossing rates, and an apparent lack of inbreeding, despite a recent bottleneck in population history. This population genomic research addresses key issues in evolution and conservation biology, providing valuable insights for safeguarding genetic diversity in this unique species.

Summary: The fundamental goal of rare plant translocation is to create self-sustaining populations with evolutionary resilience for long-term persistence. Short-term benchmarks may be misleading for predicting future growth and viability. Factors influencing translocation outcomes vary across time frames and success metrics.

Summary: This study investigated the genetic diversity of Camellia chekiangoleosa and found that the genetic diversity was low overall, with high diversity in central populations and high genetic differentiation among populations. The low genetic diversity can be attributed to small population sizes, bottleneck effects, inbreeding within populations, and low gene flow among populations.

Summary: Rare and endangered plant species (REPs) in China are at high risk of extinction, but there is a lack of comprehensive and up-to-date review on their conservation. This paper collected studies and achievements on REPs conservation, including surveys, in situ and ex situ conservation, reintroduction, propagation, legislation, public participation, and progress in implementing the Convention on Biological Diversity. Despite advancements in policies, protection systems, research, education, and international collaborations, conservation efficiency is hindered by the conflict between economic growth and biodiversity conservation in China. More work should be done on investigation, observation, advanced technologies, and application-oriented research to meet biodiversity goals.

Summary: Understanding the temporal dynamics of spatial genetic structure is crucial for assessing habitat fragmentation impacts on genetic diversity and reproductive viability in long-lived plant populations. Our study on the shrub Conospermum undulatum embedded in an urban area revealed a historical high structural connectivity influencing genetic diversity. Despite current intense fragmentation, similar genetic diversity levels and weak spatial genetic structure were found. Variations in reproductive performance were explained by genetic, environmental, and combined factors, emphasizing the importance of historical habitat dynamics in conservation strategies.

Summary: The mating system of the endemic plant Moehringia tommasinii in northwestern Adriatic showed high variation among populations, with genetic structuring and occurrences of hybridization and selfing. The presence of gene flow and weak reproductive barriers between M. tommasinii and co-occurring M. muscosa pose conservation challenges. Local extinction resulting from hybridization may disrupt mating patterns and floral polymorphism of M. tommasinii.

Summary: Endemic plants in high mountains are at high risk due to climate change. Temporal demographic variation, genetic differentiation and plasticity all play important roles in the population dynamics of high mountain endemic species. By studying the population dynamics of Primula farinosa subsp. modesta in four subalpine sites, it was found that the interaction between site and year primarily explained the temporal variation in population growth rate. Different sites showed inconsistent patterns in their contributions to the temporal deviation of population growth rate. However, within sites, growth or stasis had significant negative correlations with temporal deviation. Removing the correlations among vital rates alleviated temporal fluctuations in population growth rate.

Summary: Understanding the variation in population genetic structure is crucial for conservation planning and effective management strategies for imperiled species. We studied four desert spring invertebrates and found differences in population genetic structure, which can be attributed to differences in habitat preference and dispersal ability. This highlights the importance of considering population genetic variation in conservation efforts.

Summary: This study assessed the population size of Rare Endemic Plant Species (REPS) Picea martinezii and Picea mexicana, and evaluated their potential distributions and possibilities for assisted migration within Mexico and worldwide. The results showed that assisted migration would only be feasible for P. martinezii in limited marginal areas in Mexico, while P. mexicana could potentially be translocated to several large areas outside Mexico.

Summary: The study focused on the genetic diversity and population structure of the clonal endemic plant species Sambucus wightiana in the Himalayan region, detecting two sub-populations and significant variability among different genotypes. The moderate to high genetic diversity observed may provide insurance against climate change and support further spread of S. wightiana.

Summary: Genetic diversity is crucial for species survival during environmental changes, and understanding the distribution and amount of genetic diversity across multiple species is essential for conservation. Rare oak species generally have lower genetic diversity than common oaks, with small population size and geographic range possibly correlating with genetic diversity.

Summary: This study focuses on how anthropogenic changes impact genetic processes associated with extinction risk in the orchid Platanthera leucophaea. It found that genetic parameters were strongly linked to population size, with habitat loss and patch isolation playing a role in genetic diversity and structure. Small populations showed lower genetic diversity, indicating the need for continued monitoring by resource managers to prevent genetic declines. Contrary to expectations, critically small populations exhibited negative inbreeding values, suggesting non-random mating and selection for less inbred individuals.

Summary: This study used target enrichment, gene tree/species tree methods, and morphological analysis to reconstruct the phylogenetic history and evaluate taxon circumscriptions of Oenothera sect. Calylophus. The study found improved support for species relationships by combining exons and flanking noncoding regions. It also discovered evidence for multiple evolutionary origins of bee pollination, edaphic specialization on gypsum, and permanent translocation heterozygosity in the group. The study applied newly emerging techniques and dense infraspecific sampling to effectively reconstruct the complex history of the rapid radiation.

The results show high levels of inbreeding and low diversity within collections under current practices. Crosses between different collections result in progeny with increased genetic diversity, larger size, and higher fertility.

Summary: Phenological variation within populations has ecological and evolutionary consequences, but the genetic basis of intraspecific variation in the duration of life-cycle events is poorly understood. This study demonstrates that genetic factors explain a significant proportion of the variation in the timing and duration of multiple life-cycle events in Salix hookeriana.

Summary: This study demonstrated the importance of animal pollinators in pollen and seed dispersal and showed that different pollinator functional groups can have differential impacts on genetic diversity. The research focused on two closely related taxa, Oenothera gayleana and O. hartwegii subsp. filifolia, and found that genetic structure is primarily driven by pollen dispersal.
