Connections between the Atlantic and the Amazonian forest avifaunas represent distinct historical events
AbstractThere is much evidence to support past contact between the Atlantic and the Amazon forests through the South American dry vegetation diagonal, but the spatiotemporal dynamics of this contact…

It is shown that the Atlantic Forest of eastern South America probably expanded, rather than contracted, during the last glacial period, and the role of the emerged Brazilian continental shelf played a major, yet neglected, role on the evolution of this biodiversity hotspot During glacial periods.
Phylogeography and historical demography of the neotropical stingless bee Melipona quadrifasciata (Hymenoptera, Apidae: incongruence between morphology and mitochondrial DNA

No evidence of genetic structure in relation to the tergal stripes was found, indicating that the morphological trait regarding the pattern of stripes on tergites is not an accurate diagnostic for the subspecies of M. quadrifasciata.

This study shows that the Tocantins River has probably been the historical barrier promoting population divergence in fire‐eye antbirds, and its results have important implications for a better understanding of the importance of large Amazonian rivers in vertebrate diversification in the Neotropics.
Contrasting phylogeographic signatures in two Australo‐Papuan bowerbird species complexes (Aves: Ailuroedus)
Phylogeographical patterns in both catbird complexes, respectively, both comply and deviate from other lowland and mid‐mountain taxa in the region, highlights that taxon‐specific properties, such as their historical spatial and ecological distributions, capacity to disperse and tolerance to habitat changes, affect the phylogeographic histories of organisms.
Geographic distribution and spatial differentiation in the color pattern of abdominal stripes of the Neotropical stingless bee Melipona quadrifasciata (Hymenoptera: Apidae)

The observed patterns of geographic differentiation of M. quadrifasciata suggests the occurrence of repeated events of geographical isolation, followed by range expansion, that occurred probably during the cycles of climatic changes in the Pleistocene.
The spatio-temporal colonization and diversification across the Indo-Pacific by a ‘great speciator’ (Aves, Erythropitta erythrogaster)

The results support the view that observed latitudinal gradients of genetic divergence among avian sister species may have been affected by incomplete knowledge of taxonomic limits in tropical bird species, and suggest that sea-level fluctuations during the Pleistocene may have promoted gene flow only locally.
Genetic Diversity of Melipona mandacaia SMITH 1863 (Hymenoptera, Apidae), an Endemic Bee Species from Brazilian Caatinga, Using ISSR

The correlation between genetic and geographic distances suggests isolation by distance and contributes to describing the genetic diversity of endemic organisms from Caatinga and may help future efforts to preserve this threatened biome.

This is the first example of an AF organism that does not show phylogeographic breaks caused by vicariant events associated to climate change and geotectonic activities in the Quaternary, and shows that the history of organism diversification in this megadiverse Neotropical forest is complex.
Avian host composition, local speciation and dispersal drive the regional assembly of avian malaria parasites in South American birds
Combining macroecological patterns and biogeographic processes, this study reveals that haemosporidian parasites are capable of circumventing geographic barriers and dispersing across biomes, although constrained by environmental filtering.
