Phylogeny of subtribe Gonolobinae (Apocynaceae‐Asclepiadoideae) based on molecular and morphological data with a revised generic classification

TAXON, Volume 75, Issue 2, April 2026.
Abstract The presently most densely sampled molecular phylogeny of the widespread New World subtribe Gonolobinae is presented, including about 35% of the ca. 520 species. Sampling focused on an even representation of the three main areas of total Gonolobinae distribution, South America, Central/North America, and the West Indian Islands, and the ...

The Seasonal Impact of the Island Mass Effect on Coastal Biogeochemistry and Phytoplankton Assemblage: The Case of the Tropical and Volcanic Island of Guadeloupe (French West Indies)

Journal of Geophysical Research: Oceans, Volume 131, Issue 4, April 2026.
Abstract The Island Mass Effect (IME) in tropical regions remains understudied, despite its potential to fertilize oligotrophic oceanic gyres and impact on higher trophic levels. Guadeloupe provides an ideal case study of IME due to its diverse nutrient sources, dual exposure to the Caribbean Sea on the western coast and Atlantic Ocean on the eastern ...

Navigating Cetacean Mitochondrial Genome Data: Identifying Coverage and Deficiencies in Public Repositories

Molecular Ecology Resources, Volume 26, Issue 3, April 2026.
ABSTRACT Genetic reference databases underpin a wide range of molecular approaches used to study cetacean biodiversity, including environmental DNA (eDNA), yet their reliability depends critically on data completeness, taxonomic accuracy, and metadata quality.

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

Two new cis-Andean species of the South American catfish genus Megalonema allied to trans-Andean Megalonema xanthum, with description of a new subgenus (Siluriformes: Pimelodidae)

Neotropical Ichthyology
A revised diagnosis of the pimelodid catfish genus Megalonema is given based on synapomorphic features of the Weberian complex and gas bladder. Megalonema xanthum from the Magdalena River is redescribed.

Solar and Wind Energy Variability in Tropical South America: Seasonal Ocean‐Atmospheric Modulators

Meteorological Applications, Volume 33, Issue 2, March/April 2026.
Climate variability affects renewable energy production and thus considering it in planning is essential for achieving sustainable development. We present how climate (ocean‐atmospheric) variability modes modulate wind and solar radiation variability, thereby influencing renewable power generation in tropical South America. El Niño/Southern Oscillation

Breaking the Temporal Resolution Barrier: Projected Performance of Hybrid Gravity Satellite Ensemble by the Early 2030s

Earth's Future, Volume 14, Issue 3, March 2026.
Abstract Limitations in the temporal resolution of contemporary gravity satellite missions hinder the precise monitoring of rapid Earth surface mass changes. By the early 2030s, unprecedented high‐temporal monitoring of Earth's dynamic mass redistribution will be available using the temporal gravity field derived from the Hybrid Gravity Satellite ...
