Physicochemical characterization of crude and refined oil of Proboscidea parviflora seeds (Uña de gato)

open access: yesGrasas y Aceites, 1993
Searching for seeds as new sources of oleaginous that can cover the national needs, it was studied the oil of Proboscidea parviflora. This oil was extracted from the seed with hexane in a Soxhlet apparatus, and its physical and chemical properties were ...

No safe refuge? Contrasting effects of hunting on rainforest mammal persistence and (re)colonisation

open access: yesJournal of Applied Ecology, Volume 63, Issue 6, June 2026.
Our results imply that hunting not only targets areas used as refuges by wildlife, but also reduces recolonisation potential and may therefore alter source–sink dynamics. We recommend spatially targeted community‐led actions to limit hunting where wildlife still persists through the creation of no‐hunting areas to ensure the long‐term persistence of ...

Evolutionary and Ecological Determinants of the Phenology of Births in Wild Large Herbivores, a Systematic Review

open access: yesMammal Review, Volume 56, Issue 2, June 2026.
This semi‐systematic review supports the two dominant drivers of birth phenology: the seasonality and predation hypotheses. Even though there is evidence of their importance, the effects of female, offspring and population characteristics remain marginally accounted for. Asian and South and Central American species are currently understudied.

(−)-6-epi-Artemisinin, a Natural Stereoisomer of (+)-Artemisinin in the Opposite Enantiomeric Series, from the Endemic Madagascar Plant Saldinia proboscidea, an Atypical Source

open access: yesMolecules, 2021
Chemical and biological investigation of the Madagascar endemic plant Saldinia proboscidea led to the isolation of an isomer of artemisinin, (−)-6-epi-artemisinin (2). Its structure was elucidated using a combination of NMR and mass spectrometry.

Patterns and Drivers of Knowledge Gaps in Global Databases of Mammal Traits

open access: yesDiversity and Distributions, Volume 32, Issue 5, May 2026.
ABSTRACT Aim Knowledge gaps in biodiversity, particularly in species traits, can hinder an accurate understanding of species roles in ecosystems, limiting our comprehension of ecosystem functions, maintenance and stability. In this study, we quantified data completeness in terrestrial mammals trait databases to identify knowledge gaps and data biases ...
