    Measuring stability in ecological systems without static equilibria by Adam Thomas Clark, Lina K. Mühlbauer, Helmut Hillebrand, Canan Karakoç

    Published 2022-12-01
    “…Moreover, these variability estimates can be used to forecast dynamics, classify underlying sources of stochastic dynamics, and estimate the “exit time” before a state change takes place (e.g., local extinction events). Importantly, the time‐delay embedding methods that we employ make very few assumptions about the functions governing deterministic dynamics, which facilitates applications in systems with limited data and a priori biological knowledge. …”

    Critical shifts on spatial traits and the risk of extinction of Andean anurans: an assessment of the combined effects of climate and land-use change in Colombia by William José Agudelo-Hz, Nicolás Urbina-Cardona, Dolors Armenteras-Pascual

    Published 2019-10-01
    “…The effects of climate change and habitat loss could lead to potential extinction events in Andean frogs. Extent of suitable habitat, and especially the area of occupancy are appropriate spatial traits that could be used to assess extinction risks in species sensitive to local habitat modification by climate change and land-use change.…”

    Comparative phylogeography of parasitic Laelaps mites contribute new insights into the specialist-generalist variation hypothesis (SGVH) by Conrad A. Matthee, Adriaan Engelbrecht, Sonja Matthee

    Published 2018-09-01
    “…In addition, since specialist species are more prone to local stochastic extinction events with their hosts, they will show lower levels of intraspecific genetic diversity when compared to more generalist. …”

    Ordovician ironstone of the Iberian margin: Coastal upwelling, ocean anoxia and Palaeozoic biodiversity by Peir K. Pufahl, Alexandra D. Squires, J. Brendan Murphy, Cecilio Quesada, Stephen W. Lokier, J. Javier Álvaro, Jason Hatch

    Published 2020-09-01
    “…New data suggest that minor extinction events punctuating the Great Ordovician Biodiversification Event may be traced to these anoxic waters, which in addition to Fe, were also enriched in biologically toxic, redox sensitive trace elements. …”

    Evidence for Cascades of Perturbation and Adaptation in the Metabolic Genes of Higher Termite Gut Symbionts by Xinning Zhang, Jared R. Leadbetter

    Published 2012-08-01
    “…We suggest that symbiont extinction events, sweeping gene losses, evolutionary radiations, relaxation and reemergence of key nutritional pressures, convergent evolution of similar traits, and recent gene invasions have all shaped gene composition in the symbiotic gut microbial communities of higher termites, currently the most dominant and successful termite family on Earth.…”

    Estimated divergence times of Hirsutella (asexual morphs) in Ophiocordyceps provides insight into evolution of phialide structure by Jiaojiao Qu, Yeming Zhou, Jianping Yu, Jian Zhang, Yanfeng Han, Xiao Zou

    Published 2018-07-01
    “…A direct relationship between Hirsutella (asexual morphs) and the Cretaceous–Tertiary extinction was not found, which suggested that the diversity of phialides is more likely to be caused by long-term environmental adaptation and evolution rather than dramatic extinction events. This evolutionary result might correspond to the background of important biological and geological events in the late Cretaceous occurring near the divergence times of Hirsutella (asexual morphs).…”

    Published 2021-05-01
    “…Even after atmospheric oxygen concentrations rose to modern-like values, the ocean episodically continued to develop regions of euxinic or ferruginous conditions, such as those associated with past key intervals of organic carbon deposition (e.g. during the Cretaceous) and extinction events (e.g. at the Permian–Triassic boundary). …”

    A chronometric investigation of the initial peopling of the Americas by Becerra Valdivia, LA

    Published 2019
    “…The synchronous commencement of Beringian, Clovis and Western Stemmed cultural traditions is also identified, and their overlap with the last appearance dates for 18 extinct genera suggests that human expansion was a key driver behind animal extinction events. Notably, these findings overturn the widespread notion that North America was first penetrated only after 16-15,000 years ago.…”
