N2-fixing tropical legume evolution: a contributor to enhanced weathering through the Cenozoic?
Fossil and phylogenetic evidence indicates legume-rich modern tropical forests replaced Late Cretaceous palm-dominated tropical forests across four continents during the early Cenozoic (58-42 Ma). Tropical legume trees can transform ecosystems via their ability to fix dinitrogen (N2) and higher leaf N compared with non-legumes (35-65%), but it is unclear how their evolutionary rise contributed ...
متن کاملEarly reproduction for dinosaurs
During the Miocene period, from 25 to 12 million years ago, climate change drove plants and animals to evolve toward their modern forms and distribution. The fossil and geological records show considerable fluctuation in global temperature during this time, but not all proxies for atmospheric CO2 data show a link between CO2 and Miocene climate. Wolfram Kürschner et al. tap a new source of CO2 ...
متن کاملEcological conservatism in the ‘‘living fossil’’ Ginkgo
—The living species Ginkgo biloba is phylogenetically isolated, has a relictual distribution, and is morphologically very similar to Mesozoic and Cenozoic congenerics. To investigate what adaptations may have allowed this lineage to persist with little or no morphological change for over 100 Myr, we analyzed both sedimentological and floral data from 51 latest Cretaceous to middle Miocene Ginkg...
متن کاملEffect of Modified Atmosphere Packaging on Aril Physico-chemical and Microbial Properties of Two Pomegranate Cultivars (Punica granatum L.) Grown in Iran
Background and Objectives: Edible parts of pomegranate fruits are a rich source of bioactive compounds. The present research examines the effect of modified atmosphere packaging on the fruit physico-chemical and microbial properties of two commercial pomegranate cultivars grown in Iran. Materials and Methods: The arils were packaged and stored under four different atmospheres. All of the pac...
متن کاملDifferences in the photosynthetic plasticity of ferns and Ginkgo grown in experimentally controlled low [O2]:[CO2] atmospheres may explain their contrasting ecological fate across the Triassic–Jurassic mass extinction boundary
Background and Aims Fluctuations in [CO 2 ] have been widely studied as a potential driver of plant evolution; however, the role of a fluctuating [O 2 ]:[CO 2 ] ratio is often overlooked. The present study aimed to investigate the inherent physiological plasticity of early diverging, extant species following acclimation to an atmosphere similar to that across the Triassic-Jurassic mass extincti...
