The roles of geography and environment in divergence within and between two closely related plant species inhabiting an island‐like habitat
This work tested the relative contribution of geographic and environmental isolation in genetic and phenotypic divergence within and between two species of the figwort Ameroglossum inhabiting spatially isolated habitats, known as inselbergs.

Ameroglossum manoel-felixii, a new species of AmeroglossUM, is described and illustrated here, and morphologically compared with A. pernambucense.
Two new genera and species of Linderniaceae (Lamiales) from inselbergs in northeastern Brazil: morphological and karyological evidence
During field studies of the inselbergs of northeastern Brazil, two potentially new species of were discovered, but because their morphology differs greatly from Ameroglossum and each other, the two new species are described in separate genera.
An overview of the Brazilian inselberg genus Ameroglossum (Linderniaceae, Lamiales), with the description of seven new species
It is hypothesized that the evolution of this genus Ameroglossum is driven by the diversity of their hummingbird pollinators, and seven new species are proposed.
Reproductive ecology of Ameroglossum pernambucense (Scrophulariaceae): is this ornithophilous and threatened shrub highly adapted to a naturally fragmented habitat?

Study of two populations of A. pernambucense determined if three reproductive features facilitate the colonisation of new areas and the gene flow among the outcrops, and interpreted the reproductive traits observed as highly adapted to its fragmented condition.
Functional decoupling between flowers and leaves in the Ameroglossum pernambucense complex can facilitate local adaptation across a pollinator and climatic heterogeneous landscape

It is suggested that TL and AN are functionally linked to fit pollinators and sufficiently decoupled from developmentally related floral traits (SL) and vegetative traits (LL).
Are Brazilian cervids at risk of prion diseases?
Despite the lack of CWD reports in Brazil, the examined codons (95, 96, 116, 132, 225, and 226) of the PRNP gene showed potential CWD susceptibility in Brazilian deer.

The predominant role of cross-pollination among small, isolated populations as the main force against genetic erosion is suggested, suggesting natural genetic recovery (NGR) in more remote populations.

The use of 15 polymorphic nuclear microsatellite markers for A. pernambucense in conservation and microevolutionary studies in Ameroglossum are discussed, as well as in the investigation of the importance of pollen-mediated gene flow in keeping genetic diversity in rare species with patchily distributed populations using progeny arrays.
