    Published 2022-06-01
    “…We present new δ<sup>18</sup>O and δ<sup>13</sup>C signatures of pedogenic carbonate nodules from paleosols in the Campanian–Maastrichtian Fundo El Triunfo Formation and in the upper Eocene–middle Miocene Sambimera Formation to reconstruct the isotopic composition of paleo-meteoric water and the floristic biome. We compare these results to modern isotopic values from a newly obtained modern water transect to interpret the environmental evolution of this area and its relationship with the neighboring Eastern Cordillera. …”

    Changes in composition, diversity and structure of woody plants in successional stages of tropical dry forest in southwest Mexico Cambios en la composición, diversidad y estructura... by R. Carlos Almazán-Núñez, María del Coro Arizmendi, Luis E. Eguiarte, Pablo Corcuera

    Published 2012-12-01
    “…Early stages were dominated by typical pioneer species but species of mature forests were present throughout the chronosequence, and therefore the species plant distribution between stages may be explained by the initial floristic composition model. Because sites from all stages had similar number of species, our study does not support the intermediate levels of disturbance hypothesis. …”

    Resprouters Versus Reseeders: Are Wild Rooibos Ecotypes Genetically Distinct? by J. Brooks, N. P. Makunga, K. L. Hull, M. Brink-Hull, R. Malgas, R. Roodt-Wilding

    Published 2021-12-01
    “…Dahlgren (Fabaceae) or rooibos, is a strict endemic species, limited to areas of the Cederberg (Western Cape) and the southern Bokkeveld plateau (Northern Cape) in the greater Cape Floristic Region (CFR) of South Africa. Wild rooibos, unlike the cultivated type, is variable in morphology, biochemistry, ecology and genetics, and these ecotypes are broadly distinguished into two main groups, namely, reseeders and resprouters, based on their fire-survival strategy. …”
