A new catfish species of Microcambeva Costa & Bockmann, 1994 (Siluriformes: Trichomycteridae) from southern Brazil, with a redescription of M. ribeirae Costa, Lima & Bizerril, 2004

Journal of Fish Biology, EarlyView.
Abstract Among the few species of Microcambeva reported as occurring in more than one hydrographic basin, M. ribeirae has been previously listed from both the Ribeira de Iguape and the Guaraqueçaba basins. However, morphological and molecular analyses revealed that the specimens from Guaraqueçaba represent a new species, which is described in this ...

Stable Higgs bundles over positive principal elliptic fibrations

, 2018
Let $M$ be a compact complex manifold of dimension at least three and $\Pi : M\rightarrow X$ a positive principal elliptic fibration, where $X$ is a compact K\"ahler orbifold. Fix a preferred Hermitian metric on $M$.

An updated classification of growth forms in non‐geniculate coralline algae (Corallinophycidae, Rhodophyta)

Journal of Phycology, EarlyView.
Abstract The current challenge of defining growth forms in the non‐geniculate coralline red algae was addressed. Since the 19th century, those who have worked on this large and globally distributed group of algae have tried to summarize and systematically describe their growth forms. This effort resulted in a plethora of terms, which could sometimes be

On the degree of Polar Transformations -- An approach through Logarithmic Foliations

, 2007
We investigate the degree of the polar transformations associated to a certain class of multi-valued homogeneous functions. In particular we prove that the degree of the pre-image of generic linear spaces by a polar transformation associated to a ...

Vast, overlooked peat, and organic soils in Brazil's Cerrado: carbon storage, dynamics, and stability

New Phytologist, EarlyView.
Summary Tropical peatlands are critical for climate mitigation due to their dual role as major carbon sinks and methane sources. In rainforests, high and stable rainfall supports peat accumulation in tropical climates. However, groundwater‐fed peatlands in seasonally dry tropical ecosystems remain poorly understood, despite their potential importance ...

Commuting Challenges for Big Cities: How to Tackle Particulate Matter Human Exposure?

CLEAN – Soil, Air, Water, Volume 54, Issue 4, April 2026.
ABSTRACT Air quality in large cities is a global public health issue that has received increasing attention in recent decades. The dynamics of atmospheric pollutant concentrations form a complex system influenced by meteorology, topography, emission sources, and fleet composition, interacting in a nonlinear pattern. We monitored particulate matter (PM)

Impacts of Low‐Level Jets on Moisture Transport to the Pantanal, Brazil

International Journal of Climatology, Volume 46, Issue 3, 15 March 2026.
The moisture transports from the tropics to the subtropics by the low‐level jets (LLJs) east of the Andes crossing the Pantanal region. Four LLJs, east of the Andes, were identified and selected with correspondent Lagrangian moisture transport. The LLJ moisture source regions contribute to Pantanal (~63.5%) and precipitation increased (~30%) during LLJ

Osteology of the Feeding Apparatus of Chilean Flamingo Phoenicopterus chilensis (Aves: Phoenicopteridae)

Journal of Morphology, Volume 287, Issue 3, March 2026.
1. The skull features a broad, dorsoventrally flattened frontal region articulating with an elongated upper jaw that is complemented by the mandible's downward bend along its proximal half. 2. The low mechanical advantage in the mandible is attributed to the reduced and shallow insertion areas of the adductor muscles, which are positioned close to the ...
