Summary: In this study, we investigated the phylogeny and evolution of Tillandsioideae using comparative analysis of plastid DNA sequences. We found that plastid markers provided strong support for phylogenetic relationships and identified additional markers for future studies. Furthermore, we discovered plastome rearrangements and shifts in evolutionary trait rates associated with taxonomic changes in Tillandsioideae.

Summary: The study aimed to assess the patterns and determinants of spatiotemporal variation in fertility, mating systems, and gene flow in the epiphytic bromeliad Vriesea gigantea. The results showed that the observed variation in fertility, mating systems, and gene flow in this species are attributable to selfing adaptation and edge effects.

Summary: Stigmatodon enigmaticus is a newly described lithophytic taxon found in the Atlantic Forest hotspot of Southeastern Brazil. It has unique floral features associated with ornithophily, a contrast to other Stigmatodon species. Due to its restricted habitat, small population size, and threats from invasive species, Stigmatodon enigmaticus is considered critically endangered. This finding highlights the importance of protecting the currently unprotected Serra do Padre angelo.

Summary: Studying the transmission of genetic diversity between generations is crucial for assessing the survival prospects of fragmented forest tree populations. This is especially urgent for rare, endangered species at high risk of extinction and highly susceptible to climate change. In this study, the gene flow patterns of the IUCN red-listed Serbian spruce population were assessed for the first time using parentage analysis. The results showed that fire disturbance triggered natural regeneration and increased pollen immigration. The study provides essential information for the dynamic management and conservation of this rare and endangered species.

Summary: Seed sourcing strategies are crucial for identifying genetic material that meets future climatic conditions and social demands. This study analyzes different local seed sourcing approaches and their limitations. The research confirms the abundance of local species and genetic pools, but highlights the differences in their importance and constraints related to approved materials and seed production areas. The study suggests alternative pools to meet social demands under current regulations on marketing of reproductive materials.

Summary: Habitat fragmentation and degradation have a significant impact on an organism's gene flow and extinction risk. Understanding the effects of landscape composition and scale on gene flow is crucial for conservation decision-making. Using a landscape genetics approach, we identified sagebrush habitat as the primary driver of connectivity for Gunnison sage-grouse.

Summary: The study conducted on Indo-Pacific bottlenose dolphins in Perth found four behavioral communities with similar genetic structures but small differentiation due to related individuals within communities. The high levels of contemporary migration and related individuals among communities suggest a panmictic genetic population with continuous gene flow. Despite genetic similarity, each social community should be considered a distinct ecological unit for conservation due to exposure to different threats and occurrence in different habitats.

Summary: Commiphora wightii (Arnott) Bhandari, also known as 'Guggal', is a critically endangered medicinal plant species with varying population densities in different regions affected by altitude differences. Low genetic diversity, moderate gene flow, and ongoing genetic drift and differentiation were observed, indicating the populations are experiencing genetic changes. The correlation between pairwise geographical distance and genetic distance was statistically significant.

Summary: Genetic drift and divergent selection are important factors affecting population differentiation in the herbaceous perennial plant Pitcairnia lanuginosa. The study showed extremely low genetic diversity and significant population differentiation, suggesting a major role of genetic drift. Divergent selection on drought tolerance traits was also observed among populations in the Cerrado region.

Summary: The movement of organisms or genes among resource patches is crucial for the persistence of natural populations. This study examined genetic isolation among populations of Deuterocohnia meziana on rock outcrops in Brazil. The results showed that only populations separated by > 70 km exhibited genetic differentiation, with pollen being the more efficient dispersal method. These findings enhance our understanding of the connectivity and isolation of fragmented populations.

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: 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: 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.

Summary: Information on species' distribution, population numbers, and biotic interactions is crucial for assessing the threat status and implementing effective conservation measures. In this study, we used ecological niche modeling to evaluate the potential distribution and reproductive biology of Discocactus ferricola. The species was found to be limited to ironstone outcrops in the Residual Plateau of Macico do Urucum in Brazil, and it exhibits xenogamy.
