Speciation is a continuous and complex process which consists of the gradual accumulation of changes and the evolution of reproductive isolation. Species that hybridize in nature are a powerful system for identifying the processes that shape genomic patterns and maintain species boundaries. Hybridization may also represent an important source of adaptive genetic variation through introgre…
In the riparian forests of the Amazon, the distribution of species is predominantly influenced by their tolerance to flooding. The flood gradient shapes habitats and delineates distinct types of rainforest, creating vital hydrological refuges for plants during periods of drought. However, these areas also face disturbances due to climate change. Ischnosiphon puberulus, which belongs to th…
Local adaptation can cause population genetic divergence and culminate in events of ecological speciation. Despite the growing literature on the role of local adaptation in population divergence, the number of these studies in the Neotropics is still incipient, where most of the terrestrial biodiversity is concentrated. The objective of this project is to understand how the process of loc…
Population heterogeneity has fundamental implications for adaptative phenotype fitness along environmental gradients. Genomic information in combination with functional attributes information, like ecophysiological tolerances and local adaptation, as well as to ecological niches, are of great importance for understanding species distribution in natural environment, both at present as in f…
Neotropics encompass large number of hotspot regions to conservation, however the knowledge about patters and process responsible to shape its outstanding biodiversity are still emerging. Multidisciplinary approaches such as, systematics, phylogeography, population genetics and genomics, ecology and morphometry can significantly contribute to identify important evolutionary processes in g…

Current climate change can lead to alterations in the cellular, molecular, morphological, and developmental traits of plants, thereby modifying their ecological interactions with the environment and other organisms. In pigmented organisms, climate change may trigger responses resulting from changes in the regulatory mechanisms of secondary metabolite biosynthesis, particularly anthocyanin…
The Atlantic Forest, located in the Neotropical region, is the fifth main biodiversity hotspots in the world, characterized by broad environmental gradients. Historical climatic changes, combined with topographic and environmental heterogeneity, have driven the rapid diversification of lineages in this region, which may be associated with processes such as hybridization, introgression, an…
Lineages with gene flow and recent divergence are excellent models for studying the evolution of reproductive barriers between populations and species, as they allow for the observation of hybrid formation and allele introgression. Bromeliads of the genus Pitcairnia have been used as a model for speciation studies involving gene flow. Pitcairnia albiflos and P. staminea are sister species…

Population heterogeneity has fundamental implications for adaptive phenotype fitness along environmental gradients. Functional traits are the measurable morphological, physiological or phenological characteristics of the organisms that potentially influence their development and that summarize the ways in which they use a resource for their development and survival. When analyzed in heter…
The Atlantic Forest is the second largest tropical rainforest in South America, and has high rates of diversity and endemism due to the great evolutionary dynamism of the region, which can be attributed to the heterogeneity imposed by the latitudinal and altitudinal gradients of its distribution. Pitcairnia flammea (Bromeliaceae) is an endemic species of the Atlantic Forest, distributed f…

Abiotic variables, such as temperature and water availability, shape species distributions across environmental gradients, determining patterns of plant community composition. However, biotic interactions can also play a crucial role in community assembly, influencing species co-occurrence and abundance distributions. Understanding the relative impact of biotic and abiotic interactions ac…
Speciation is a continuous and complex process which consists of the gradual accumulation of changes and the evolution of reproductive isolation. Here, we will investigate the divergence process of two species of Pitcairnia genus (Bromeliaceae). P. albiflos and P. staminea adapted to naturally fragmented environments in the Atlantic Rainforest. These species have a high population structu…
To disentangle the role of the different evolutive forces involved in populational divergence is an aim in molecular ecology. The local adaptation process - which may lead to population divergence and culminate in ecological speciation events - acts not only on Single Nucleotide Variations (SNVs), but also on Structural Variants (SVs) such as Presence-Absence Variations (PAVs) of genes. H…
Species are isolated by a diversity of reproductive barriers that act either before or after fertilization, also called prezygotic or postzygotic reproductive isolation. Studies on epigenetic variation as a mechanism producing barriers to reproduction and speciation are now emerging. Such studies revealed that the role of DNA methylation in gene expression may also contribute to reproduct…
