In island‐like habitats, geographic isolation facilitates population and species divergence by constraining gene flow, while environmental isolation can enhance divergence. We tested the relative contribution of geographic and environmental isolation in genetic and phenotypic divergence within and between two species of the figwort Ameroglossum (Scrophulariaceae) inhabiting spatially isolated habitats, known as inselbergs. 
Drivers of bromeliad leaf and floral bract variation across a latitudinal gradient in the Atlantic Forest
TLDR
The biogeographical break detected suggests a role of tectonic activity and climatic oscillations in promoting species divergence and diversification and how geography and environmental changes through time shape floral bracts and leaves in similar ways is identified.
Landscape Features and Climatic Forces Shape the Genetic Structure and Evolutionary History of an Oak Species (Quercus chenii) in East China
TLDR
It is concluded that mountainous areas with higher climatic stability are more likely to be glacial refugia that preserved higher phylogenetic diversity, while plains and basins may have acted as dispersal corridors for the post-glacial south-to-north migration.
Genome resequencing reveals demographic history and genetic architecture of seed salinity tolerance in Populus euphratica
Natural populations of Populus euphratica in northwest China are divided into four clades exhibiting strong geographical distribution patterns. A total of 38 single nucleotide polymorphisms were
Hybridization and hybrid zone stability between two lizards explained by population genetics and niche quantification
TLDR
The genetic structure of two lizard species, Salvator merianae and Salvator rufescens, is analysed at a microscale within a climatic niche analysis framework to reveal the main factors that contribute to the stability of their hybrid zone.
Pollen flow within and among isolated populations of two rare, self-compatible plant species from inselbergs of Northeast Brazil
TLDR
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 Landscape Genetic Signature of Pollination by Trapliners: Evidence From the Tropical Herb, Heliconia tortuosa
TLDR
It is concluded that maintaining habitat connectivity to sustain the foraging routes of trapliners may be essential for the maintenance of pollen-mediated gene flow in human-modified landscapes.
Morphological variability and genetic diversity in Carex buxbaumii and Carex hartmaniorum (Cyperaceae) populations
TLDR
A considerable genetic affinity between the two sedge species is indicated and the taxonomic status of the putative infraspecific taxa within C. buxbaumii requires further studies throughout the distribution range, addressing habitats, morphology and genetics.
Karyotype differentiation in Ameroglossum (Linderniaceae) and closely related genera endemic to Brazilian inselbergs
TLDR
The karyotypical similarities among the species of Ameroglossum, Catimbaua, Cubitanthus and Isabelcristinia suggest a close relationship between representatives of Linderniaceae typical of inselbergs.
An overview of the Brazilian inselberg genus Ameroglossum (Linderniaceae, Lamiales), with the description of seven new species
TLDR
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.

Adaptation with gene flow across the landscape in a dune sunflower
TLDR
Studying the divergence of Helianthus petiolaris ecotypes living in active sand dunes and adjacent non‐dune habitat finds that landscape resistance models with lower resistance in the dunes performed well as predictors of genetic distances among subpopulations.
SPECIATION IN HAWAIIAN ANGIOSPERM LINEAGES: CAUSE, CONSEQUENCE, AND MODE
TLDR
The role of speciation in shaping the regional species pool is discussed and evidence for allopatric and parapatric modes is provided, with 15 cases of each.
Rock outcrop orchids reveal the genetic connectivity and diversity of inselbergs of northeastern Brazil
TLDR
Both orchids Epidendrum cinnabarinum and E. secundum showed similar patterns of genetic diversity and structure, highlighting the importance of seed-restricted gene flow and genetic drift as drivers of plant diversification in terrestrial islands such as inselbergs.
Population differentiation and species cohesion in two closely related plants adapted to neotropical high‐altitude ‘inselbergs’, Alcantarea imperialis and Alcantarea geniculata (Bromeliaceae)
TLDR
The results indicate a high potential for inselbergs as venues for studies of the molecular ecology and genetics of continental radiations, such as the one that gave rise to the extraordinary diversity of adaptive strategies and phenotypes seen in Bromeliaceae.
Adaptation and colonization history affect the evolution of clines in two introduced species.
TLDR
Phenotypic clines generally persisted when tested against the neutral expectation, although some clines disappeared (and one cline emerged) when the effects of genetic ancestry were statistically removed, and Colonization history, estimated using genetic markers, is a useful null model for tests of adaptive trait divergence.
Evolutionary diversification and geographical isolation in Dubautia laxa (Asteraceae), a widespread member of the Hawaiian silversword alliance.
TLDR
Results indicate that geographical separation has aided diversification in D. laxa, whereas ecologically associated morphological differences are not associated with neutral genetic differentiation, suggesting that, despite the stunning ecological adaptation observed, geography has also played an important role in the Hawaiian silversword alliance plant adaptive radiation.
Association of genetic and phenotypic variability with geography and climate in three southern California oaks.
TLDR
Comparison of the association of geography and climate of three oak species in an environmentally heterogeneous region of southern California illustrates that climate influences tree response at all organizational levels, but the important climate factors vary depending on the level and on the species.
