An Overview of Orchidaceae from Brazil: Advances and Shortfalls After 400 Years of Studies Open
The historical background of studies on Brazilian Orchidaceae dates back almost 400 years. In this review, we provide an overview of the current knowledge on Brazilian Orchidaceae across three thematic axes: 1. diversity, distribution, and…

Dispersal Ability Reduces Thermal Specialization and Prevents Climate‐Driven Extinctions in a Neotropical Rainforest Open
Dispersal ability is a key factor in determining a species' realized niche. However, it remains unclear whether dispersal ability directly, indirectly, or neutrally affects environmental specialization and species' tolerance ranges. Here, …

What are the consequences of water stress on the development of late postzygotic reproductive isolation in an orchid hybrid zone? Open
Studies on reproductive isolation in angiosperms often focus on early postzygotic barriers, whereas research on established hybrid generations and their ecological interactions remains limited. This study aimed to compare the morphophysiol…

Mating system, morphological and genetic evidence endorse clonality as an essential reproductive mode in <i>Daphnopsis filipedunculata</i> (Thymelaeaceae), a dioecious and endemic species from the Amazon Open
Background and Aims: Clonality is characterized by the formation of independent individuals of the same genotype that are capable of reproducing and propagating vegetatively. Although clonality is an important mechanism that facilitates th…

Dispersal ability reduces thermal specialization and prevents climate-driven extinctions in a Neotropical rainforest Open
Dispersal ability is a key determinant of the realized species niche. Yet, whether dispersal ability influences environmental specialization and exerts a direct, indirect, or null effect on species’ tolerances is still unclear. Here, we as…

Speciation with gene flow between two Neotropical sympatric species (<i>Pitcairnia</i> spp.: Bromeliaceae) Open
The study of mechanisms that generate new species is considered fundamental for broad areas of ecology and evolution. Speciation is a continuous process in which reproductive isolation is established, and it is of fundamental importance to…

Underlying microevolutionary processes parallel macroevolutionary patterns in ancient neotropical mountains Open
Aim Ancient climatic fluctuations are invoked as the main driving force that generates the astonishing biodiversity in ancient mountains. As a result, endemism and spatial turnover are usually high and few species are widespread amongst en…

Differential gene expression reveals mechanisms related to habitat divergence between hybridizing orchids from the Neotropical coastal plains Open
Background Closely related hybridizing species are ideal systems for identifying genomic regions underlying adaptive divergence. Although gene expression plays a central role in determining ecologically-based phenotypic differences, few st…

Deforestation reduces the genetic structure of an epiphytic weed across space and time: an IBM approach Open
Deforestation has allowed the massive dispersal and reproduction of some plants that are commonly referred to as weeds. The rapid spread of many weeds into newly disturbed landscapes is often boosted by clonal growth and self-fertilization…

Underlying microevolutionary processes parallel macroevolutionary patterns in ancient Neotropical Mountains Open
Aim The exceptional species-richness associated with mountains worldwide is linked to the fragmented topography of these areas, responsible for constantly isolating populations during periods of climatic fluctuations. Consequently, endemis…
