Selecting for Seed Size Diversity Can Support a Variety of Plant Colonization Strategies in Caatinga Restoration

open access: yesBiotropica, Volume 58, Issue 5, September 2026.
ABSTRACT Seed traits offer valuable insights into colonization strategies under climatic unpredictability. In seasonally dry tropical forests, such traits help explain species adaptations to water availability, which is critical for effective restoration.

The complete chloroplast genome sequence of an economic plant Salix wilsonii

open access: yesMitochondrial DNA. Part B. Resources, 2019
In this study, we report the first complete chloroplast (cp) genome sequence of Salix wilsonii. The cp genome is 155,026 bp in length, exhibiting a typical quadripartite structure of a large single copy (LSC) region of 83,917 bp, a small single copy (SSC)

Human Disturbances and Woody Flora Diversity Along a Caatinga–Brejo de Altitude Gradient in Northeastern Brazil

open access: yesBiotropica, Volume 58, Issue 5, September 2026.
ABSTRACT Tropical dry forests are among the ecosystems most threatened by human activities worldwide. The Caatinga, a seasonally dry tropical forest restricted to northeastern Brazil, exemplifies this scenario, as local human populations strongly depend on forest resources.

Large‐scale nuclear and plastid phylogenomic analyses inform an updated Angiosperm Phylogeny Group classification: APG V

open access: yesJournal of Systematics and Evolution, Volume 64, Issue 5, Page 845-874, September 2026.
This revision of the APG classification considers the extensive recent analyses of hundreds of nuclear and plastid genes for many angiosperm species. Although previous versions of the APG classification were largely based on uniparentally inherited markers (plastid DNA, largely maternally inherited), there has emerged since APG IV extensive evidence of
