Pararaucaria delfueyoi sp. nov. from the late jurassic canadon calcareo formation, chubut, Argentina: Insights into the evolution of the cheirolepidiaceae [PDF]
, 2013 The discovery of 16 cylindrical conifer seed cones at the Estancia Vilan locality in the Late Jurassic Canadon Calcreo Formation of Chubut Province, Patagonia, Argentina, provides anatomically preserved specimens, allowing for the description of a second

Austral Ecology, Volume 50, Issue 7, July 2025.ABSTRACT Disease caused by plant pathogens can shape plant community structure and composition, especially if the host species plays important ecological roles. The New Zealand kauri, Agathis australis, is a foundation species that modifies its soil environment and, by doing so, it acts as an ecological filter selecting for a distinctive suite of plant

Journal 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

Journal of Vegetation Science, Volume 36, Issue 2, March/April 2025.This study investigates understorey sapling dynamics and the effects of Phytophthora agathidicida, within stands that were dominated by the susceptible conifer Agathis australis through repeat measurements. Data P. agathidicida‐induced overstorey mortality appeared to induce a growth release in otherwise supressed A.

Molecular Ecology Resources, Volume 25, Issue 2, February 2025.Abstract Phytophthora agathidicida is a virulent soil pathogen of Aotearoa New Zealand's iconic kauri tree species (Agathis australis (D. Don) Lindl.) and the primary causal agent of kauri dieback disease. To date, only a few control options are available to treat infected kauri that are expressing symptoms of dieback disease.

Body size and evolutionary rate analyses reveal complex evolutionary history of Alvarezsauria
Cladistics, Volume 41, Issue 1, Page 135-155, February 2025.Abstract Some of the smallest examples of dinosaurian body size are from alvarezsaurians, an enigmatic group of maniraptoran coelurosaurians with a peculiar combination of anatomical features unique among theropods. Despite the large number of alvarezsaurian species described worldwide and the increased understanding this has provided, the body‐size ...
