    Life history predicts global population responses to the weather in terrestrial mammals

    John Jackson, Christie Le Coeur, Owen Jones
    In mammals, how populations respond to extremes in the weather is related to their pace of life, with shorter living species having stronger responses than their longer living counterparts.

    Flowering time and seed dormancy control use external coincidence to generate life history strategy

    Vicki Springthorpe, Steven Penfield
    Models of plant behaviour show that flowering early in a warming world is an adaptive strategy to insulate progeny seed behaviour from the affects of climate change.

    Variation in albumin glycation rates in birds suggests resistance to relative hyperglycaemia rather than conformity to the pace of life syndrome hypothesis

    Adrián Moreno Borrallo, Sarahi Jaramillo Ortiz ... Francois Criscuolo
    Bird species with higher plasma glucose show comparatively lower albumin glycation, suggesting the evolution of glycation resistance mechanisms, and terrestrial carnivores present higher glycation than omnivores.

    Larger but younger fish when growth outpaces mortality in heated ecosystem

    Max Lindmark, Malin Karlsson, Anna Gårdmark
    Elevated growth rates and increased size-at-age leads to a larger population size structure, despite higher mortality and a younger population after three decades of exposure to 5–10°C higher temperatures in a large-scale natural climate change experiment.

    Implications of being born late in the active season for growth, fattening, torpor use, winter survival and fecundity

    Britta Mahlert, Hanno Gerritsmann ... Sylvain Giroud
    Being born late in the active season is associated with a fast life history in a hibernating species, the garden dormouse (Eliomys quercinus).

    Intra-species differences in population size shape life history and genome evolution

    David Willemsen, Rongfeng Cui ... Dario Riccardo Valenzano
    Population genetics in turquoise killifish wild populations reveals how small population size and genetic drift determine the accumulation of deleterious gene variants leading to short lifespan.

    Experimental evaluation of the importance of colonization history in early-life gut microbiota assembly

    Inés Martínez, Maria X Maldonado-Gomez ... Jens Walter
    Experiments in ex-germ-free mice establish a measurable effect of colonization history on gut microbiota assembly, illuminating a potential cause for the high levels of unexplained individuality in host-associated microbial communities.

    The activity-dependent histone variant H2BE modulates the life span of olfactory neurons

    Stephen W Santoro, Catherine Dulac
    A genome-organizing protein that is present only in the olfactory system of mice has been found to orchestrate changes in the relative numbers of different odor-sensing neurons on the basis of how active these neurons are.

    Personality links with lifespan in chimpanzees

    Drew M Altschul, William D Hopkins ... Alexander Weiss
    Among captive chimpanzees, higher agreeableness males and higher openness females survive longer.
    1. Cancer Biology

    A generalized theory of age-dependent carcinogenesis

    Andrii Rozhok, James DeGregori
    The multi-stage model of carcinogenesis requires the incorporation of aging-dependent somatic selection and life history-dependent evolution of species-specific tumor suppressor mechanisms in order to generalize carcinogenesis across tissues and species.
