Microclimate drives demographic compensation in a narrow endemic tropical species

New Phytologist, Volume 250, Issue 1, Page 166-180, April 2026.
Summary Demographic compensation occurs when reductions in some vital rates are offset by increases in others, allowing populations to maintain similar performance across varying environments. This mechanism may help explain species' ecological distributions and range limits, yet its role at microenvironmental scales remains poorly understood.

Mitochondrial Genomes of Mammals from the Brazilian Cerrado and Phylogenetic Considerations for the Orders Artiodactyla, Carnivora, and Chiroptera (Chordata: Mammalia)

Life
We assembled and annotated the complete mitochondrial genomes of Lycalopex vetulus (hoary fox), Cerdocyon thous (bush dog), Tayassu pecari (white-lipped peccary), and Tadarida brasiliensis (Brazilian free-tailed bat).

Stochastic Modelling of Daily Precipitation in Semi‐Arid Regions Using Markov Chains and Parametric Distributions

International Journal of Climatology, Volume 46, Issue 4, 30 March 2026.
This study applies stochastic rainfall models combining Markov Chains with gamma and mixed exponential distributions to a semi‐arid climate in Northeast Brazil. Model structures were evaluated using Bayesian Information Criterion (BIC), with maximum likelihood (MLM) for parameter estimation and cumulative distribution functions (CDFs) for validation ...

Sentinel‐5p Reveals Unexplained Large Wildfire Carbon Emissions in the Amazon in 2024

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract In 2024, the Amazon region experienced severe wildfires driven by exceptional drought conditions. Advanced fire emission models estimated Amazon carbon monoxide (CO) emissions between 28 and 62 Tg during the main August‐September Amazon fire season. The majority of the 2024 CO emissions came from (understorey) forest fires, unlike the previous

Unveiling the Dietary Selection of Lowland Tapirs (Tapirus terrestris) in a Tropical Rainforest

Ecology and Evolution, Volume 16, Issue 3, March 2026.
Large terrestrial herbivores, such as lowland tapirs (Tapirus terrestris) present many dietary ecological roles in their habitat. In this article, we investigated the diet of lowland tapirs in a tropical rainforest combining different techniques such as DNA metabarcoding, fieldwork, and plant functional traits.

Spatial Structure Explains Morphological Variation Better Than Climatic Gradients in the South American Rattlesnake (Crotalus durissus)

Ecology and Evolution, Volume 16, Issue 3, March 2026.
We evaluated whether climatic gradients or spatial structure better explain body size variation in the South American rattlesnake (Crotalus durissus) across its wide geographic range. After explicitly accounting for spatial autocorrelation, climatic variables were not significant predictors of body size in either sex, whereas sex‐specific spatial ...

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.

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

Two new records for the flora of Paraguay: Stemodia diplohyptoides and S. lobelioides (Plantaginaceae:Gratioleae)

Nordic Journal of Botany, Volume 2026, Issue 3, March 2026.
Stemodia diplohyptoides M.M.Sosa & Dematt. and S. lobelioides Lehm. (Gratioleae, Plantaginaceae) are reported for the first time in Paraguay, found in Alto Paraná and Presidente Hayes departments, respectively. These new records extend the known geographical range of both species, representing the northern records to date, S.
