Overcoming barriers to build partnerships for managing plant invasions under global change

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract Non‐native plant invasions are a cross‐boundary conservation challenge, requiring coordinated management and policy responses underpinned by science. Global change is expected to exacerbate this challenge by changing abiotic and biotic drivers of invasive plant distribution, abundance, and impact. Current approaches may no longer be effective,

Phylogenetic reconciliation provides new insights into the evolutionary diversification of the glutamine synthetase gene family in seed plants

open access: yesThe FEBS Journal, Volume 293, Issue 3, Page 859-877, February 2026.
Phylogenetic analyses of glutamine synthetase (GS) in seed plants revealed that all three major evolutionary lineages (GS2, GS1a, and GS1b) must have been present in the common ancestor, with GS2 being the first lineage to diverge. Unlike GS1b, GS1a and GS2 are usually single‐copy genes, even though they underwent duplications that resulted in ...

Cold spot microrefugia hold the key to survival for Brazil's Critically Endangered Araucaria tree

open access: yesGlobal Change Biology, 2019
Brazil's Araucaria tree (Araucaria angustifolia) is an iconic living fossil and a defining element of the Atlantic Forest global biodiversity hotspot. But despite more than two millennia as a cultural icon in southern Brazil, Araucaria is on the brink of

Spore density and root colonization by arbuscular mycorrhizal fungi in preserved or disturbed Araucaria angustifolia (Bert.) O. Ktze. ecosystems Densidade de esporos e colonização radicular por fungos microrrízicos arbusculares em ecossistemas de Araucaria angustifolia (Bert.) O. Ktze. preservados e impactados

open access: yesScientia Agricola, 2006
Araucaria angustifolia (Bert.) O. Ktze., a native forest tree from Brazil, is under extinction risk. This tree depends on arbuscular mycorrhizal fungi for growth and development, especially in tropical low-P soils but, despite being a conifer, Araucaria ...

Overlooked Parrot Seed Dispersal in Australia and South America: Insights on the Evolution of Dispersal Syndromes and Seed Size in Araucaria Trees

open access: yesFrontiers in Ecology and Evolution, 2019
While Psittaciformes (parrots and allies) are well recognized as highly-mobile seed predators, their role as seed dispersers has been overlooked until very recently.
