Systematics of Marmosa Subgenus Micoureus With Emphasis in ‘rapposa’ Group (Didelphidae, Marmosini): Geographic Variation and Revalidation of M. budini

Zoologica Scripta, EarlyView.
ABSTRACT Micoureus is the most species‐rich subgenus within the genus Marmosa. Conflicting arrangements regarding the number of species comprising this subgenus have been proposed and the validity of M. budini has been debated. Here, we used an approach integrating genetic and morphological data were conducted to reanalyze the ‘rapposa’ group ...

pCramoll and rCramoll as New Preventive Agents against the Oxidative Dysfunction Induced by Hydrogen Peroxide

Oxidative Medicine and Cellular Longevity, Volume 2015, Issue 1, 2015., 2015
Oxidative stress plays an important role in the induction of cell death and is associated with various pathologic disorders; therefore, the search for natural products that attenuate the effects produced by oxidant agents is greatly increased. Here, the protective effects of native lectin from Cratylia mollis seeds (pCramoll) and recombinant Cramoll 1 (

Host–Parasite Interaction Networks of Helminths of Sigmodontine Rodents in Two Different Areas of the Brazilian Atlantic Forest

Ecological Research, Volume 41, Issue 3, May 2026.
Two helminth‐rodent networks were analyzed for two distinct areas. Network modularity, nestedness, and degree of specialization were calculated for each network. Higher network modularity than nestedness and high network specialization were observed in both networks, suggesting functional and/or taxonomic specialization between helminth species and ...
