Summary: The Strigiformes are facing challenges like habitat loss and the illegal wildlife trade, but biomolecular research using microsatellite markers has provided a valuable tool for tracking genetic variability and aiding in conservation efforts. Testing highly polymorphic microsatellite loci has led to the development of a panel of 12 markers that can identify individuals across multiple species, benefiting authorities in forensic investigations and aiding in genetic research for both wild and captive populations.

Summary: Forest growth models serve as valuable support tools for forest recovery assessment and management, providing diagnostic or prognostic information. The diffusive-logistic growth model is applied in this study to predict forest recovery in Brazilian Atlantic rainforest preservation areas. The results reveal that forest recovery could take several decades to stabilize without negative interventions, and the model presented can aid in decision-making and policy formulation for forest recovery.

Summary: This study aimed to understand the distribution of trace metals in the main soils of tropical coastal rainforest ecosystems in Bahia state, Brazil. It found significant differences in trace metal concentrations between different soil classes. The study also highlighted the potential misinterpretations caused by composite sampling based on soil layers instead of horizons. The use of multivariate regression models provided a fast, low-cost, and reliable method to predict trace metal concentrations in individual soil samples.

Summary: Given the speed of climate change caused by humans, endemic species may not have enough time to adapt and avoid extinction. This study investigated the origin of rainfall that affects the phylogenetic diversity of rainforest frogs and the impact of microclimate differences on the morphological traits of isolated populations. It also examined how deforestation in the Amazon can affect ecosystem services essential for maintaining the biodiversity of the Atlantic rainforest. The results suggest that morphological traits and population dynamics of Atlantic Forest frogs are influenced by the Amazonian flying rivers, which are now threatened by temperature anomalies caused by global warming and deforestation.

Summary: This study investigated the genetic structure of Tomoplagia spp. in the rupestrian montane grasslands of the Espinhaco Mountain Range, Brazil, revealing the absence of simple geographic and host-associated genetic structure in these specialized herbivores. Despite the specialized and intimate nature of their host association, the studied Tomoplagia species showed no clear host-associated genetic differentiation; instead, genetic variation presents a mosaic pattern across hosts and localities.

Summary: Habitat fragmentation poses a threat to biodiversity and increases species exposure to edge effects. In the Brazilian Cerrado savanna, ant colonies of Odontomachus chelifer were found to have similar genetic diversity and structure at both the edge and interior of a fragmented area, although there was a slight increase in observed heterozygosity at fragment edges. This study provides a first step in understanding the effects of edge effects on genetic diversity of ant colonies in tropical environments.

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 Agronomic Institute of Campinas (IAC) in Brazil developed a grapevine breeding program in the 1940s to create new grape varieties suitable for the country's tropical and subtropical regions. After 50 years and over 2,000 crosses, only 130 hybrids remain in the IAC collection with little information about their genetic characteristics. This study genotyped these hybrids and assessed their genetic diversity and population structure, as well as identifying their true parentage and verifying their pedigrees.

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.
