Are genetic databases sufficiently populated to detect non-indigenous species? [PDF]

open access: yes, 2016
Correct species identifications are of tremendous importance for invasion ecology, as mistakes could lead to misdirecting limited resources against harmless species or inaction against problematic ones.

Biochemical Characterization of a Kunitz‐Type Protease Inhibitor From Mimosa regnellii and Its Effects on Melanoma Cell Viability and Angiogenesis

open access: yesChemistry &Biodiversity, Volume 23, Issue 4, April 2026.
A Kunitz‐type serine protease inhibitor (JTI) purified from Mimosa regnellii seeds selectively targets melanoma cells. JTI triggers mitochondrial apoptosis, increases ROS and Ca2+ levels, arrests the cell cycle, and suppresses migration and angiogenesis without affecting healthy cells.

Extending Specimens to Save Plant DNA: Structuring Department DNA Collections in Times of Biodiversity Loss

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
Small department DNA collections can be created through a six‐step holistic process that integrates DNA extracts, DNA‐rich tissues, and herbarium vouchers to generate extended specimens. We propose a revision to the international biobanking strategy (the Dynamo scheme) that leverages the strengths of interconnected small departmental collections.

The largest subunit of RNA polymerase II from the Glaucocystophyta: functional constraint and short-branch exclusion in deep eukaryotic phylogeny

open access: yesBMC Evolutionary Biology, 2005
Background Evolutionary analyses of the largest subunit of RNA polymerase II (RPB1) have yielded important and at times provocative results. One particularly troublesome outcome is the consistent inference of independent origins of red algae and green ...
