Seasonal and Within‐Day Variation on Hummingbirds Visits and Dominance Hierarchy in a Brazilian Cerrado Area

Austral Ecology, Volume 51, Issue 3, March 2026.
ABSTRACT Plant‐hummingbird interaction networks can be influenced by environmental conditions and resources, which vary seasonally and daily. We aimed to understand how variations in these parameters across these two temporal windows influence patterns of plant‐hummingbird interactions and hummingbirds dominance hierarchies in a Brazilian Cerrado ...

Genomic Prediction and Genome‐Wide Association Analysis of Heat Tolerance for Milk Yield in Buffaloes Using a Reaction Norm Model

Journal of Animal Breeding and Genetics, Volume 143, Issue 2, Page 342-353, March 2026.
ABSTRACT The aim of this study was to evaluate the impact of incorporating genomic information on the estimation of genetic (co)variance components and the accuracy of breeding values for milk yield under varying thermal environments, and to identify SNPs associated with genes that play significant roles in heat tolerance.

Streamflow Elasticity to Precipitation Distribution and Potential Evapotranspiration Across South America

Hydrological Processes, Volume 40, Issue 2, February 2026.
Graphical abstract summarizing the modelling experiments used to quantify streamflow elasticity to changes and temporal redistribution of precipitation across South America, highlighting stronger effects of seasonal redistribution and larger responses in humid climates. ABSTRACT This study examines the sensitivity of mean, high and low streamflows (i.e.

Observed Changes in Maximum and Minimum Temperatures and Daily Temperature Range in the Iberian Peninsula and Balearic Islands Between 1952 and 2022

International Journal of Climatology, Volume 46, Issue 2, February 2026.
Strong warming trends have been identified across the Iberian Peninsula, particularly since the 1980s and across all seasons. Increases in minimum temperature dominate at low‐altitude urban stations (below 250 m), while the most pronounced maximum temperature trends occur at elevations above 1500 m, especially in summer.

Observational Requirements for Quantifying the Diurnal Cycle of XCO2 From Space

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 1, 16 January 2026.
Abstract Spatiotemporal variations in atmospheric carbon dioxide (CO2) provide a means to quantify surface fluxes of carbon over a range of space and timescales. NASA's Orbiting Carbon Observatory‐3 (OCO‐3), aboard the International Space Station, is the first CO2‐monitoring mission to observe the sunlit portion of the diurnal cycle of total column ...
