Isolated in the highlands, found in the museum: A new species of Characidium (Crenuchidae) from a Bolivian National Park, with a CT scan revealing features

open access: yesJournal of Fish Biology, EarlyView.
Abstract A new species of Characidium is described from a small, isolated river in the highland areas of Noel Kempff Mercado National Park, Bolivia. The new taxon can be diagnosed by the presence of a relatively broad and conspicuous dark midlateral stripe extending from the tip of snout to the base of the caudal fin, markedly darker than the vertical ...

Flavobacterium oreochromis From Farmed Tambaqui (Colossoma macropomum): Insights Into Genetic, Phenotypic and Pathogenic Diversity

open access: yesJournal of Fish Diseases, EarlyView.
ABSTRACT Flavobacterium spp. are the etiological agents of columnaris disease. Although there is evidence that columnaris poses a significant threat to the farming of tambaqui (Colossoma macropomum), there remains a large gap in understanding the genetic and phenotypic diversities of columnaris‐causing bacteria (CCB).

Confirming the impact origin of the São Miguel do Tapuio structure, northeastern Brazil

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract The São Miguel do Tapuio structure (SMT) is a remarkable, nearcircular feature of about 21 km diameter, centered at 5°37.6′ S, 41°23.3′ W in Piauí state, northeastern Brazil. The structure is located within the sedimentary strata of the Paleozoic–Mesozoic Parnaíba Basin and predominantly comprises sandstones of the Devonian Pimenteiras and ...

Araguainha Dome, Brazil: A polygonal impact structure due to a complex pre‐impact regional structural framework

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract We investigated the structural framework of the north–northwestern Paraná Basin in Brazil to test whether the pre‐impact structures in this region may have had any influence on the first‐order formation and morphostructure of the Araguainha impact structure (AIS).

Tree stem methane emissions are regulated by site‐level biogeochemistry over species identity in Amazon floodplain forests

open access: yesNew Phytologist, EarlyView.
Summary Tree stems in Amazonian floodplains emit substantial methane (CH4), yet controls on emission variability remain unclear. Emissions span orders of magnitude between várzea (nutrient‐rich) and igapó (nutrient‐poor) forests and among trees, suggesting controls beyond flooding.
