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: Our study confirmed hybridization between two invasive cichlids in a Neotropical reservoir, with most hybrids carrying the CR haplotype of one species. The presence of high genetic diversity in the nuclear microsatellite loci suggests an increase in local adaptability and establishment success in novel areas. The intermediate color patterns of most hybrids highlight the usefulness of these traits as visual tools for the identification of ongoing hybridization between these invasive species.

Summary: The study on Cytonuclear discordance in the Australian endemic plant genus Adenanthos revealed that the incongruence between plastid and nuclear phylogenies was not only caused by incomplete lineage sorting, but also due to extensive ancient introgression and recent chloroplast capture and introgression. This deep reticulation coincided with the rapid radiation of the genus during the Miocene and suggests that ancient introgression may play an important role in the evolution of the Australian flora more broadly.

Summary: Obligate pollination mutualisms often exhibit high species specificity, but host sharing and pollinator sharing can occur in current ecological time. This study used genome-wide sequence data to investigate the impact of departures from strict specificity on hybridization and introgression in Panamanian fig species and their associated wasp species. The results showed ongoing hybridization and historical introgression in fig species, but no evidence of hybridization or introgression in the associated wasp species. This suggests that pollinators in obligate pollination mutualisms are reproductively isolated even when different species mate in shared hosts.

Summary: Environmental DNA (eDNA) sampling is a powerful and efficient approach for collecting information about species, and it may also provide information about population-level genetic variability. In this study, the researchers used eDNA sampling to estimate the genetic diversity and structure of an invasive fish species in the Great Lakes region. The study found that the genetic patterns observed from eDNA analysis were consistent with conventional tissue-based estimates. This research highlights the potential for eDNA sampling to reveal detailed population characteristics that can inform monitoring and management plans for difficult-to-sample species.

Summary: The study on Atlantic Forest White Morpho butterflies shows that there is no clear species diversification and population structure among the populations, suggesting that the current distinction between the two species is unreasonable. Northern samples exhibit more intragroup structure, and clustering tests indicate the existence of three genetic clusters, with turnover between the states of Paran ' a and Sa similar to o Paulo.

Summary: Life-history traits, such as reproductive allocation, sexual expression, sex ratio, and reproductive success, are important for the ecology and evolution of species. In this study, we investigated reproductive traits in 10 meta-populations of Fissidens flaccidus Mitt. Our results showed that relative reproductive allocation in perigonia and sporophytes is greater than perichaetia. Furthermore, we found a trade-off between sexual relative reproductive allocation and asexual gemma production, highlighting the importance of female ramets in asexual reproduction.

Summary: This study assessed the genetic diversity and population structure of nine populations of Aechmea distichantha from Brazil using a plastidial DNA region and ten nuclear microsatellite markers. The results showed that A. distichantha has low-to-moderate plastidial genetic diversity and moderate-to-high nuclear genetic diversity. High genetic differentiation was found among A. distichantha populations in different geographical locations, which may be a result of its mixed reproductive system and restricted gene flow. The findings suggest that in situ conservation is the most appropriate protection measure for these plant populations.

Summary: This study examined the relationship between reproductive allocation and vegetative growth in three sexual systems of bryophytes. It found that reproductive allocation differs between sexes and sexual systems, and that it is negatively related to vegetative growth. However, these relationships may differ for truly monoicous species with shorter intersexual distances, so further research and comparison are needed.

Summary: Estimating effective population size (N-e) is important, but it remains challenging for organisms with complex life-history traits. In this study, we examined how clonal versus sexual reproduction affected N-e in two populations of the orchid Cypripedium calceolus. The results showed that N-e in partially clonal plants cannot be predicted solely based on the number of genets generated by sexual reproduction.

Summary: This study investigates the factors limiting the distribution of a orchid species, including abiotic factors, such as climate, and biotic factors, such as pollinator richness. The results confirm the predictions of the centre-periphery hypothesis, showing that ecological conditions and genetic patterns vary towards the edges of the species' range. This study contributes to our understanding of species distribution and has implications for conservation practices.

Summary: Mountains are known for their rich and diverse biodiversity, with the origin of this abundance often attributed to their geological history. However, even ancient mountain systems with geological stability can exhibit high levels of species and endemism. Climatic fluctuations over the past few million years are believed to have played a significant role in the diversification of mountainous biota. This study aims to evaluate the impact of climatic oscillations on the biodiversity of the Brazilian Quartzitic Mountains (BQM) in Eastern South America, using various analytical methods.

Summary: Orchis patens was previously believed to have three disjunct populations in northern Italy, Algeria/Tunisia, and the Canary Islands. While the population in the Canary Islands is commonly referred to as O. canariensis, there has been doubt about the name for the Italian taxon because the type specimen of O. patens is from the Algerian populations. In this study, we reviewed the taxonomic literature and provided a key based on recently published molecular data for these three taxa in the Orchis section Robustocalcare. We concluded that Orchis patens subsp. brevicornis is the correct name for the Italian taxon.

Summary: The study aimed to assess the lipid profile changes on Pitcairnia flammea leaves using different solvent proportions and ultrasonic ice bath extraction times, followed by a analysis of enriched lipid classes using chemometric techniques. Ultra-high performance liquid chromatography coupled with electrospray ionization mass spectrometry (UHPLC-ESI-MS) was used to gather raw data, while MS-DIAL and MetaboAnalyst platforms were utilized for data preprocessing and statistical analysis. The statistical analysis of UHPLC-ESI-MS data in both ionization modes revealed a trend distribution based on extraction time. The findings also showed that the solvent proportion had a greater impact on group separation in data samples extracted for 30 min compared to 10 and 20 min. Additionally, diacylglycerol or/and lysophosphatidylcholine were found to be favored lipid subclasses depending on the extraction time in mass spectrometry analyses using positive electrospray ionization mode.
