Conifer research

[edit]
  • Bodnar et al. (2022) reassess the anatomy and systematics of the permineralized conifer-like woods from the Triassic strata from Argentina, confirm the assignment of the logs related to the families Cupressaceae and Cheirolepidiaceae, as well as three taxa related to Araucariaceae (Agathoxylon cozzoi, Agathoxylon protoaraucana and Agathoxylon argentinum), and argue that the fossil woods previously assigned to the families Podocarpaceae and Taxaceae do not have enough preserved characters to support such assignment.[65]
  • A study on the pattern of conifer turnover across the Cretaceous-Paleogene boundary in the Raton and Denver basins (Colorado, United States) is published by Berry (2022).[66]
  • Mantzouka, Akkemik & Güngör (2022) describe fossil woods of Cupressinoxylon matromnense from the middle Miocene Eşelek volcanic deposits (Gökçeada, Turkey), preserved with feeding damage produced by members of the agromyzid genus Protophytobia, and supporting the existence of an eastern Mediterranean Miocene Climatic Optimum hotspot which additionally included Greek islands of Lemnos and Lesbos.[67]

General angiosperm research

[edit]
  • Surangea mohgaoensis, originally interpreted as fern megaspores, is reinterpreted as angiosperm fruits by Ramteke et al. (2022).[152]
  • Zhang et al. (2022) describe rich assemblages of spiny plant fossils from the Eocene (Bartonian) Niubao Formation (Tibet, China), preserving seven different spine morphologies, and interpret this finding as evidence of the presence of a diversity of spiny plants in Eocene central Tibet, as well as evidence of a rapid diversification of spiny plants in Eurasia around that time.[153]
  • A preliminary report on a new fossil angiosperm flora of the Lesvos Petrified Forest at Akrocheiras east of Sigri on Lesbos, Greece is given by Kafetzidou et al. Preliminary taxa identifications are given and commentary on the climactic implications are made.[154]
  • A study aiming to determine the relationship between past atmospheric CO2 and temperature fluctuations and the shifts in diversification rates of Poaceae and Asteraceae is published by Palazzesi et al. (2022).[155]

Research

[edit]
  • Review of the studies on the origin of the land flora is published by Bowman (2022).[187]
  • A study on the evolution of body plans of members of Viridiplantae, based on a review of the fossil record, molecular data and developmental biology, is published by Niklas & Tiffney (2022).[188]
  • A study on the biodiversity of land plants at the equator during their first major diversification in the Late Silurian–Early Devonian is published by Wellman et al. (2022).[189]
  • A study on the evolution of heterospory during the Devonian is published by Leslie & Bonacorsi (2022).[190]
  • Seven coniferous nurse logs that have been colonized by conifer and equisetalean roots are reported from four Permian intervals in the Ordos Basin (China) by Feng et al. (2022), indicating that conifer tree stems probably functioned as hosts to both conspecific and interspecific seedlings in the Cathaysian Flora.[191]
  • A study on the impact of the Intertropical Convergence Zone in the emerging South Atlantic region on Aptian plant communities from eight Brazilian sedimentary basins is published by Carvalho et al. (2022), who report evidence of an overall predominance of xerophytic plants, attesting to more dry conditions, and of a humidification trend towards the end of the late Aptian resulting in the predominance of hydrophytes, hygrophytes, tropical lowland flora and upland flora, indicative of prevalence of lowland and montane rainforests.[192]
  • A study on the distribution and relative abundances of major plant groups from the Albian Gates Formation (Alberta, Canada) is published by Kalyniuk et al. (2022).[193]
  • A study on the relationship between whole-genome duplication, seed traits and the selectivity of the survival of plants during the Cretaceous–Paleogene extinction event is published by Berry & Jaganathan (2022).[194]
  • New Oligocene flora is described from the Dong Ho Formation (Vietnam) by Huang et al. (2022), who interpret the studied fossils as evidence of long-term environmental, floristic and vegetational stability in this region since the Paleogene.[195]
  • Gentis et al. (2022) describe fossil wood specimens from the Miocene Natma Formation (Myanmar), representing an assemblage dominated by members of the families Fabaceae and Dipterocarpaceae, interpreted as coming from different types of low altitude forest ecosystems (tropical wet evergreen, tropical dry and deciduous, and tropical littoral), and interpreted as indicative of a monsoonal climate with an alternance of a dry season and a wet season.[196]
  • Abundant compression floras dominated by angiosperm leaves are described from two sites of probable Pliocene age in Brunei by Wilf et al. (2022), who interpret these floras as evidence of dipterocarp-dominated lowland rainforests in the Malay Archipelago before the Pleistocene.[197]
  • A study on the impact of the extinct Neotropical megafauna on the variability in plant functional traits and biome geography in Central and South America is published by Dantas & Pausas (2022).[198]
  • A study on plant material from rock overhangs from mid-late Holocene sites along the Kawarau-Cromwell-Roxburgh Gorges in Central Otago (New Zealand), much of which was likely transported as roosting material or consumed by moa birds, and on its implications for the knowledge of the mid-late Holocene regional vegetation of Central Otago and the knowledge of vegetation changes since mid-late Holocene, is published by Pole (2022).[199]
  • A study on the role of hydraulic failure in the evolution of early vascular plants is published by Bouda et al. (2022), suggesting that drought selection played a key role in the diversification of vascular arrangements beginning with the Devonian explosion.[200]
