Quaternary climatic changes led to variations in sea level and these played a significant role the generation of marine terrace deposits South Atlantic Coastal Plain. The main consequence increase was local extinction or population displacement, such that coastal species would be found around new coastline. Our goal investigate effects on geographical structure variability genetic lineages from Petunia endemic We employed phylogeographic approach based plastid sequences obtained individuals...
The garden petunia is derived from Petunia axillaris (white flowered) and a purple-flowered species in the P. integrifolia group; it still unclear which was used initial crosses. This widely cultivated hybrid an ideal model for different areas of scientific inquiry.We analyzed three taxa group considered to be most probable parental candidates, along with random sample representatives that were selected their genetic variability. We cpDNA trnH-psbA trnS-trnG haplotypes seven nuclear...
The Pampas is a Neotropical biome formed primarily by low altitude grasslands and encompasses the southernmost portion of Brazil, Uruguay, part Argentina. Despite high level endemism, its significant environmental heterogeneity, Pampean species are underrepresented in phylogeographic studies, especially aquatic organisms. hydrological system resulted from long history tectonism, climate, sea changes since Neogene. In this study, we examined population genetic structure Cnesterodon...
Abstract Aim Environmental features can act as selection pressures and barriers to gene flow between populations. The genetic structuring of highly mobile but philopatric seabirds creates a paradox, the role oceanographic geographic variables is still poorly understood. In this study, we investigate influence environmental in phenotypic diversity pantropical seabird breeding islands archipelagos separated by different distances, up thousand kilometres, which differ characteristics. Location...
Abstract Territoriality is costly, and the accurate identification of intruders decision to perform aggressive responses are key behavioral traits in social animals. We studied aggression among individuals belonging close distant nests plant-ant Azteca muelleri , which lives stems pioneer tree Cecropia glaziovii . More specifically, we aim investigate if DE (dear-enemy effect—less towards neighbors than strangers) or NN (nasty-neighbor strangers neighbors) effects even none them apply for...
• Premise of the study: Microsatellite markers were developed for Petunia integrifolia subsp. depauperata with an intent to clarify taxonomic questions on P. complex, and identify a purple‐flowered parent hybrida . Methods Results: We characterized 11 microsatellite loci by screening primers using SSR‐enriched library. Genotyping two populations resulted in eight polymorphic loci. Cross‐species transferability was tested other members complex. Conclusions: The development these may...
Astyanax bimaculatus, a ubiquitous species in many Neotropical basins, is characterized by complex taxonomy and are currently considered complex. The goal of this study was to analyze 31 populations (N = 136) from southeastern Brazil using cytogenetic techniques: conventional staining, nucleolar organizer region (Ag-NOR), C-banding, 18S 5S recombinant DNA fluorescent situ hybridization (FISH) probes; molecular S72, RAG2, COI. All were 2n 50 (6m + 20sm +18st +6a); Ag-NORs predominantly...
Microsatellite primers were developed in Aureliana fasciculata var. fasciculata, a shrub that inhabits the Atlantic Rainforest, to investigate intraspecific genetic structure of species.Nine pairs microsatellite designed based on simple sequence repeat (SSR)-enriched library. Seven loci amplified successfully. Two populations A. genotyped and all polymorphic, with two five alleles per locus population detected. Cross-species amplification was achieved other members genus sister Athenaea.The...
