Smallanthus sonchifolius (Yacon) leaves: an emerging source of compounds for diabetes management [PDF]

, 2015
Diabetes mellitus is a chronic metabolic disease that develops mainly due to insulin deficiency or resistance to insulin action. All forms of diabetes are characterized by chronic hyperglycemia, which has an important role in the pathogenesis of diabetic

Are the immunomodulatory properties of Lactobacillus rhamnosus CRL1505 peptidoglycan common for all Lactobacilli during respiratory infection in malnourished mice? [PDF]

, 2018
Previously, we reported that Lactobacillus rhamnosus CRL1505 peptidoglycan (PG05) improves the innate immune response in immunocompromised-malnourished mice after Streptococcus pneumoniae infection.

Disentangling conservation asymmetries through socio‐economic transboundary factors across the Alto Paraná Atlantic Forest of South America

People and Nature, Volume 8, Issue 5, Page 1328-1348, May 2026.
Abstract Ecoregions are often defined based on homogeneous biophysical and ecological conditions and are optimal spatial units for designing conservation strategies. However, transboundary ecoregions such as the Alto Paraná Atlantic Forest (APAF) experience asymmetrical conservation outcomes, understood here as cross‐border differences, resulting from ...

Propagation of gravity waves and spread F in the low-latitude ionosphere over Tucumán, Argentina, by continuous Doppler sounding: first results [PDF]

, 2014
Results of systematic analysis of propagation directions and horizontal velocities of gravity waves (GWs) and spread F structures in low-latitude ionosphere (magnetic inclination ~27°) in Tucumán region, Argentina, are presented.

Multi‐Decadal Trends in the Low Latitude foF2 Driven by Secular Magnetic Variations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract Long‐term ionospheric trends have been widely studied, but their origin and magnitude remain subjects of debate. This study quantifies the linear trend in the F2‐region critical frequency (foF2) and its local time dependence using observations from eight low‐latitude ionosonde stations.

Temporal dynamics in functional fruit traits of native and invasive fleshy fruited plants in subtropical Andean forests

Functional Ecology, Volume 40, Issue 5, Page 1221-1232, May 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Fruits encompass the energetic and material flow between both interacting parties in frugivore‐mediated seed dispersal. Since fruit traits matter in frugivores' foraging decisions, the temporal dynamics of fruit traits might influence interaction outcomes.

Pathways of megaherbivore rewilding transitions: typologies from an Andean gradient

Elementa: Science of the Anthropocene, 2020
In most of the planet, large herbivore communities have been replaced by livestock, but this process is reversing in many places. Here, we outline and review the pathways of “megaherbivore rewilding transitions” in three social-ecological-systems of ...

Variação intraespecífica da cor da pelagem de uma espécie de pequeno roedor sul-americano [PDF]

, 2016
Intra-specific color variation is often underestimated by researchers, and among mammalian species, intra-specific differences in coloration are poorly documented for most species.
