Novel phylogenetic analysis of the Mesozoic common gymnosperm Xenoxylon Gothan reveals close affinity with extant Podocarpaceae (Coniferales)

open access: yesJournal of Systematics and Evolution, Volume 63, Issue 2, Page 469-478, March 2025.
We perform a phylogenetic analysis of the Mesozoic common gymnosperm Xenoxylon to understand the systematic relationship with extant conifers. Data come from four nucleotide regions (trnL‐F, trnK‐matK, rbcL, psbA‐trnH), xylological characters, and biomolecular composition of five extant conifer families and extinct Xenoxylon. Using maximum parsimony in

Lowland valleys shelter the ancient conifer Fitzroya cupressoides in the Central Depression of southern Chile [PDF]

open access: yesJournal of the Royal Society of New Zealand, 2003
Abstract The location of glacial refugia of tree taxa in Patagonia is determined primarily using data from the fossil pollen record. These data suggest that cold‐tolerant conifers such as Fitzroya cupressoides probably survived the Last Glacial Maximum in coastal areas of ...

Bristlecone Pine Maximum Latewood Density as a Superior Proxy for Millennium‐Length Temperature Reconstructions

open access: yesGeophysical Research Letters, Volume 51, Issue 15, 16 August 2024.
Abstract Bristlecone pine (Pinus longaeva) (PILO) trees exhibit exceptional longevity. Their tree‐ring width (TRW) series offer valuable insights into climatic variability. Maximum latewood density (MXD) typically correlates better with temperature variations than TRW, yet PILO MXD records are non‐existent due to methodological challenges related to ...
