    Changes in African lion demography and population growth with increased protection in a large, prey‐depleted ecosystem by Scott Creel, Matthew S. Becker, Ben Goodheart, Anna Kusler, Kachama Banda, Kambwiri Banda, Milan Vinks, Catherine Sun, Chase Dart, Stephi Matsushima, Ruth Kabwe, Will Donald, Luka Zyambo, Peter Indala, Adrian Kaluka, Clive Chifunte, Craig Reid

    Published 2025-01-01
    “…Our results demonstrate that increased protection is likely to improve the reproduction and population growth rate of lions at a large scale within an unfenced ecosystem that has been greatly affected by poaching.…”

    Fire return intervals and recruitment affect population growth rate of canopy trees in tall open forest in humid savanna by Patricia A. Werner, Stephanie J. Peacock

    Published 2024-12-01
    “…A stage‐based population model of the canopy trees was previously developed to address this question, drawing on data from three decades of experimental field studies wherein the survival, growth, and reproduction of individual marked trees were recorded under different seasonal fires and understory types to produce transition matrices among eight life history stages, and used to calculate population growth rates (λ). Here, we apply that model to determine how λ varies across a range of fire return intervals from 1 to 12 years for both early and late dry season fires, in two different understory types. …”

    Principle of Limiting Factors-Driven Piecewise Population Growth Model I: Qualitative Exploration and Study Cases on Continuous-Time Dynamics by Héctor A. Echavarria-Heras, Cecilia Leal-Ramírez, Guillermo Gómez, Elia Montiel-Arzate

    Published 2021-01-01
    “…We examine the comportment of the global trajectory of a piecewisely conceived single species population growth model. Formulation relies on what we develop as the principle of limiting factors for population growth, adapted from the law of the minimum of Liebig and the law of the tolerance of Shelford. …”
