Maternally transmitted symbionts such as Wolbachia spread within host populations by mediating reproductive phenotypes. Cytoplasmic incompatibility (CI) is a reproductive phenotype that interferes with embryonal development when infected males fertilize uninfected females. Wolbachia -based pest control relies on strong CI to suppress or replace pes...

Whole‐genome duplication (WGD, polyploidization) has been identified as a driver of genetic and phenotypic novelty, having pervasive consequences for the evolution of lineages. While polyploids are widespread, especially among plants, the long‐term establishment of polyploids is exceedingly rare. Genome doubling commonly results in increase...
Hybridization blurs species boundaries and leads to intertwined lineages resulting in reticulate evolution. Polyploidy, the outcome of whole genome duplication (WGD), has more recently been implicated in promoting and facilitating hybridization between polyploid species, potentially leading to adaptive introgression. However, because polyploid line...
Polyploidy, resulting from whole‐genome duplication (WGD), is ubiquitous in nature and reportedly associated with extreme environments and biological invasions. However, WGD usually comes with great costs, raising questions about the establishment chance of newly formed polyploids. The surprisingly high number of polyploid and mixed‐ploidy species...
Many organisms have more than two sets of chromosomes, due to whole genome duplication (WGD), and are thus polyploid. Despite usually being an ephemeral state in the history of life, polyploidy is widely recognized as an important source of genetic novelty over macroevolutionary scales. More recently, polyploidy has also been shown to facilitate in...
Whole genome duplication (WGD, polyploidization), the fusion of unreduced gametes, has been identified as a driver of genetic and phenotypic novelty. Unreduced gamete formation is common in a wide range of species, but surprisingly, few polyploidization events have shown to be ecologically successful. Positive density dependence, by minority cytoty...
Polyploidy, i.e. the occurrence of multiple sets of chromosomes, is regarded as an important phenomenon in plant ecology and evolution, with all flowering plants likely having a polyploid ancestry. Owing to genome shock, minority cytotype exclusion and reduced fertility, polyploids emerging in diploid populations are expected to face significant ch...
Biomass and wood volume estimates in forest ecosystems are fundamental to a variety of studies focusing at forest dynamics. These estimates are usually carried out through forest inventory techniques which rely upon statistical computations. This work aims at providing a new methodological approach to forest inventory processing when data is georef...
Forest inventory procedures are of utmost importance to studies of wood volume stocks, and forest structure and diversity, which provide relevant information to public policies, management plans and ecological research. The present work focused on the performance of inventory techniques in the Amazon region to evaluate wood volume stocks with highe...
The goal of the present study was to find a pattern regarding wood anatomical features for the Araucaria Forest. For that, we studied the wood anatomy of 17 tree species characteristics of this forest formation of Southern Brazil. The species were selected based on the amplified importance value. Wood samples of three individuals per species were c...
