Thinking of Melastomataceae: Revisiting Humboldt and Bonpland's Monographie des Melastomacées (1806–1823) from a historical perspective

TAXON, Volume 75, Issue 3, June 2026.
Abstract During their voyage to the Americas (1799–1804), Alexander von Humboldt and Aimé Bonpland described and collected American flora, fauna, minerals and other objects. After returning to Europe, they published several works, including Monographie des Melastomacées, initiated by Bonpland to classify this complex botanical family.

Integrative taxonomy reveals four new species of the armoured catfish genus Pareiorhina (Siluriformes: Loricariidae) from the upper Paraná River basin, Brazil

Journal of Fish Biology, Volume 108, Issue 6, Page 1906-1933, June 2026.
Abstract Four new species of the small‐sized armoured catfish genus Pareiorhina are described from mountain ranges in the Grande River drainage, upper Paraná River basin, based on morphological and molecular species delimitation methods. Molecular analyses based on the cytochrome oxidase subunit I (COI) marker recovered Pareiorhina as polyphyletic ...

An inverse latitudinal gradient in intraspecific genetic diversity of a dominant ant in the neotropical savanna

Ecosphere, Volume 17, Issue 4, April 2026.
Abstract Although latitudinal gradient of diversity (LGD) is a biogeographic pattern widely shown for distinct animal groups, some display the opposite pattern, with biodiversity peaking away from the equator. These inverse gradients may result from drivers that also overlap with extrinsic factors shaping genetic diversity across taxa, a level of ...

ASPECTOS MORFOESTRUTURAIS E MORFOESCULTURAIS DA SERRA DA CANASTRA E ENTORNO (MG)

Geography Department University of Sao Paulo, 2014
A região escolhida para este estudo carece de um mapeamento geomorfológico sistemático em escala de semi-detalhe. Em função desta lacuna, tem-se como objetivo de realizar a caracterização geomorfológica da área da Serra da Canastra e entorno, utilizando como suporte teórico metodológico as propostas de Valeriano (2008), Florenzano (2008), Borges et al.

Boundaries Within the Paepalanthus chiquitensis Species Complex (Eriocaulaceae)

Feddes Repertorium, Volume 137, Issue 1, March 2026.
ABSTRACT Four morphotypes with associated names are presented toward a more reliable circumscription of Paepalanthus chiquitensis. Morphotype I, associated with the names P. chiquitensis, P. speciosus var. bolivianus, and P. amoenus var. bolivianus, is restricted to savannas of Bolivia and western Brazil.

Time to burn: landscape drivers of fuel trait variability and fire regime in savanna ecosystems

Oikos, Volume 2026, Issue 3, March 2026.
Fuel traits are important determinants of fire behavior and regime in savannas and, thus, of how fire affects plant communities. However, whether these traits are correlated, predictable and how they are influenced by biotic and abiotic drivers remain to be rigorously evaluated.

A novel circumscription and classification for Neurolaeneae (Asteraceae)

TAXON, Volume 75, Issue 1, February 2026.
Abstract Neurolaeneae (Asteraceae) have a complicated taxonomic history. The tribe was described in 1927, but subsequently disregarded in 1977, and later reinstated as a tribe following a large‐scale phylogenetic analysis of Asteraceae in 2002. To date, this tribe has remained poorly studied and it has never been the subject of a comprehensive ...
