Activation of Nucleases, PCD, and Mobilization of Reserves in the Araucaria angustifolia Megagametophyte During Germination

open access: yesFrontiers in Plant Science, 2018
The megagametophyte of mature seeds of Araucaria angustifolia consists of cells with thin walls, one or more nuclei, a central vacuole storing proteins, and a cytoplasm rich in amyloplasts, mitochondria and lipid bodies.

Forest Recovery or Shrubland Assembly? Vegetation Dynamics in Abandoned Atlantic Forest Highland Pastures

open access: yesBiotropica, Volume 58, Issue 3, May 2026.
ABSTRACT Understanding successional trajectories in abandoned lands is critical for predicting forest recovery potential in the Atlantic Forest, a global biodiversity hotspot. Over a decade of field monitoring (2014–2025) in permanent plots in the subtropical highlands of southern Brazil, we analyzed the dynamics of tree‐shrub components in abandoned ...

Data integration advances reproductive phenology research across temporal, spatial and taxonomic scales

open access: yesEcography, Volume 2026, Issue 4, April 2026.
Climate change is altering plant reproductive phenology; however, a scarcity of long‐term, systematic monitoring hinders our ability to quantify and predict these responses in many parts of the world. We addressed this gap by demonstrating how data integration can be used to produce a synthesised record of reproductive phenology observations (flowering

POTENTIAL USES FOR Araucaria angustifolia UNDEVELOPED SEEDS

open access: yesBoletim do Centro de Pesquisa de Processamento de Alimentos
Undeveloped pinhão seeds (Falhas de Pinhão, FP) are potential by-products on the exploitation of pine cones of Araucaria angustifolia, and this material has no use and little academical research available. In this work, its chemical characterization was conducted, and new uses for this material were proposed, with focus on the potential for the food ...

Revealing patterns of endemism in the transatlantic family Chelodesmidae (Polydesmida: Diplopoda)

open access: yesCladistics, Volume 42, Issue 2, Page 159-171, April 2026.
Abstract With fossil records dating back to the Silurian/Late Ordovician, millipedes stand out as one of the earliest terrestrial animal groups. Their limited vagility and high endemism make them valuable tools for formulating and testing biogeographic hypotheses, including those related to macro‐vicariance events.

Urbanization and Seasonality Increase Introduced Plant Consumption by the World's Southernmost Parrot 城市化与季节性增加了全球最南端鹦鹉对引入植物的取食

open access: yesIntegrative Conservation, Volume 5, Issue 1, Page 86-103, March 2026.
Urbanization may alter bird foraging. Austral Parakeets (Enicognathus ferrugineus) in Patagonia rely on introduced plants in urban areas, especially in winter, despite preferring natives in the wild. This seasonal reliance on introduced species highlights urbanization trade‐offs and underscores the need to manage green areas with native plants to ...
