Streamflow Elasticity to Precipitation Distribution and Potential Evapotranspiration Across South America

open access: yesHydrological 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.

Environmental stress upon hepatopancreatic cells of freshwater prawns (Decapoda: Caridea) from the floodplain of Paraná River [PDF]

open access: yes, 2010
In order to evaluate the influence of stressed environments on hepatopancreatic cells of freshwater prawns, Macrobachium borellii Nobili, 1896 and Palaemonetes argentinus Nobili 1901, (Crustacea, Decapoda, Palaemonidae) were collected at three different ...

Landscape Genomics and Evolutionary History of Megamelus scutellaris, a Biocontrol Agent of the Invasive Water Hyacinth (Pontederia crassipes)

open access: yesEvolutionary Applications, Volume 19, Issue 2, February 2026.
ABSTRACT Understanding the evolutionary history of biological control agents in their native ranges is crucial for improving their selection, establishment, and performance across environmentally diverse regions. Phytophagous insects that specialize on aquatic plants offer particularly valuable models, as their evolutionary trajectories may be shaped ...

A Novel Sampling Protocol for Fruit‐Feeding Butterflies in Grasslands and Open Habitats

open access: yesAustral Ecology, Volume 51, Issue 1, January 2026.
This study proposed a novel sampling protocol for fruit‐feeding butterflies in grasslands and open areas in the subtropical region. The new method involves the use of Van Someren‐Rydon bait traps placed on specific supports closer to the ground, aiming to capture the true diversity of butterflies in these habitats.

Respuesta de las propiedades físicas de tres suelos de La Pampa deprimida al pastoreo rotativo Rotative grazing effects on soil physical properties of three soils of the flooding Pampa

open access: yesCiencia del Suelo, 2009
Existe escasa información referida al efecto del pastoreo rotativo sobre las propiedades físicas de los suelos. Se hipotetiza que suelos ubicados en diferentes posiciones de una toposecuencia responden en forma diferente al manejo del pastoreo. Se espera

Present and Future: Using Ecological Niche Modeling to Understand the Conservation Status of Alouatta caraya (Primates, Atelidae) and Promote Its Protection

open access: yesAmerican Journal of Primatology, Volume 87, Issue 8, August 2025.
Free‐living Alouatta caraya: the male (top left) and his females (bottom left). We used ecological niche modeling to assess the species' climate suitability both now and in future projections. Between now and 2030, there is a 31% reduction in distribution.
