    Biogeography of the stony corals (Scleractinia) of the Mexican pacific by H Reyes-Bonilla, A López-Pérez

    Published 1998-03-01
    “…There is no evidence of effective biogeographic barriers throughout the Mexican Pacific region. Local extinction events, likely caused by the narrow distribution of some species, and perhaps due to the type and frequency of transpacific colonizations, modify the normal processes of community succession, causing the Mexican Pacific to be a highly dynamic zone in terms of its coral fauna. …”

    The Future of the Extinction Plot by Joshua Schuster

    Published 2015-03-01
    “…Butler’s novel examines issues central to biopolitics and animal studies that appear specifically at the threshold of extinction events.  This essay discusses the ways her novel calls upon the reader to think self-reflexively about how extinction and genetic knowledge intertwine in contemporary cultural and scientific debates about the decline of biodiversity. …”

    Scaling laws in the evolutionary processes of marine animals over the last 540 million years by Haitao Shang

    Published 2024-02-01
    “…However, whether such patterns existed in deep-time biological systems is less investigated; the best-known example is the scaling law between the frequency and size of extinction events. Here, I show that the variation rates of biodiversity, origination intensity, extinction intensity, and body size of marine animals during the last 540 million years exhibited scaling laws. …”

    Geological duration of ammonoids controlled their geographical range of fossil distribution by Ryoji Wani

    Published 2017-11-01
    “…These relationships were somewhat blurred in the Devonian, Carboniferous, Triassic, and Jurassic, which is possibly due to (1) the course of development of a reproductive strategy with smaller hatchling sizes in the Devonian and (2) the high origination rates after the mass extinction events.…”

    Upholding science-based risk assessment under a weakened Endangered Species Act by Nicolas J. Muñoz, Debora S. Obrist

    Published 2020-12-01
    “…As global extinction rates approach those observed during the five mass extinction events in Earth’s history (Barnosky et al. 2011), robust, well-implemented conservation laws are critically needed to slow the loss of biodiversity (Westwood et al. 2019; Leclère et al. 2020).…”

    A review of recent and future marine extinctions by Pablo del Monte-Luna, Miguel Nakamura, Alba Vicente, Lilian B. Pérez-Sosa, Arturo Yáñez-Arenas, Andrew W. Trites, Salvador E. Lluch-Cota

    Published 2023-01-01
    “…A review of current methods being used to determine the loss of biodiversity from the world’s oceans reveals the need to develop and apply new assessment methodologies that incorporate standardized metrics that allow comparisons to be made among different regions and taxonomic groups, and between current extinctions and past mass extinction events. Such efforts will contribute to a better understanding of extinction risk facing marine flora and fauna, as well as the ways in which it can be mitigated.…”
