Summary: The effects of river network rearrangements on species dispersal and lineage diversification are poorly understood. By studying South American freshwater fishes, it was found that major landscape evolution events led to abrupt shifts in net diversification rates. Western Amazonia, since the Mid-Miocene, has been an important source of species dispersing to other regions. The study supports the hypothesis that landscape dynamics strongly affected the assembly and diversification of basin-wide fish faunas.

Summary: River network rearrangements have significant effects on species dispersal and lineage diversification, with major landscape evolution events associated with abrupt shifts in net diversification rates. The Western Amazonia region in South America, with its high diversification rates and extensive biotic interchange, has played a crucial role in the assembly and diversification of fish faunas.

Summary: This paper provides a detailed nomenclatural study of the name Anthurium xmacrolobum and proposes a solution to the nomenclatural confusion associated with it. The priority principle dictates that the name A. xmacrolobum should be preserved against the older name A. xdentatum, and neotypes for both names are designated in the present paper.

Summary: A new genus and species belonging to Araceae from southern Ecuador, named Vivaria calvasensis, was described. This species inhabits semi-arid inter-Andean mountains and has distinct morphological traits that separate it from other related genera. This study provides molecular evidence based on the matK gene to support the new genus.

Summary: The chloroplast genome of Anthurium andraeanum Linden 1877 was successfully assembled and analyzed. Its size is 162,560 bp, consisting of a large single-copy (LSC) region, a small single-copy (SSC) region, and two inverted repeat regions (IRA and IRB). The genome contains 124 genes, including protein-coding genes, tRNAs, rRNAs, and a pseudogene. Phylogenetic analysis revealed that A. andraeanum belongs to the subfamily Pothoideae and is sister to A. huixtlense.

Summary: Philonthina is the largest subtribe of Staphylinini, with most of its species found in tropical areas. The origin of this diversity is not well understood, but through molecular and geographical studies, it was found that Philonthina originated during the Late Cretaceous and diversified into five main lineages during the Eocene. The Neotropical lineage (NL) of Philonthina originated in northwestern South America and the Andes around 64.2 million years ago and further diversified into different clades during the Miocene.

Summary: This study confirmed the presence of finger-like colleters in Anthurium andraeanum, which is the first report of colleters in the Araceae family. The colleters were found in the apex of young leaves, spathes, and unexpanded cataphylls, as well as in various locations on expanded cataphylls. These structures develop early and senesce quickly, and they produce a polysaccharide-rich secretion. The discovery of colleters in Araceae has implications for understanding their functional roles and evolutionary significance.

Summary: The study aimed to test the predictions of the vicariance model in shaping biogeographical regions for endemic snakes in the Atlantic Forest using revised point locality data. The results indicated non-random biogeographical regions in the Atlantic Forest for snakes, congruent with previously identified areas based on other organisms, validating the central predictions of the vicariance model.

Summary: We describe a new species of Anthurium (Anthurium huaytae) from central Peru, which is also the first record for subsect. Rupicola in Peru. Anthurium huaytae resembles A. amnicola but differs in its habitat, spathe color, cataphyll persistence, and flower shape.

Summary: A new species of Anthurium, named Anthurium knopflmacherianum, has been discovered in Los Tuxtlas, Veracruz, Mexico. This species is morphologically similar to A. verapazense, but it can be distinguished by its shorter geniculum, longer anterior lobe, inflorescence with a longer peduncle, and violet-purple spadix during flowering.
