Does thermoregulatory behavior maximize reproductive fitness of natural isolates of Caenorhabditis elegans?

BACKGROUND: A central premise of physiological ecology is that an animal's preferred body temperature should correspond closely with the temperature maximizing performance and Darwinian fitness. Testing this co-adaptational hypothesis has been problematic for several reasons. First, reproductive fitness is the appropriate measure, but is difficult to measure in most animals. Second, no single fitness measure applies to all demographic situations, complicating interpretations. Here we test the co-adaptation hypothesis by studying an organism (Caenorhabditis elegans) in which both fitness and thermal preference can be reliably measured.RESULTS: We find that natural isolates of C. elegans display a range of mean thermal preferences and also vary in their thermal sensitivities for fitness. Hot-seeking isolates CB4854 and CB4857 prefer temperatures that favor population growth rate (r), whereas the cold-seeking isolate CB4856 prefers temperatures that favor Lifetime Reproductive Success (LRS).CONCLUSIONS: Correlations between fitness and thermal preference in natural isolates of C. elegans are driven primarily by isolate-specific differences in thermal preference. If these differences are the result of natural selection, then this suggests that the appropriate measure of fitness for use in evolutionary ecology studies might differ even within species, depending on the unique ecological and evolutionary history of each population.</p

How to Fly (In Ten Thousand Easy Lessons)

In her second poetry collection, Barbara Kingsolver offers reflections on the practical, the spiritual, and the wild. She begins with how to poems addressing everyday matters such as being hopeful, married, divorced; shearing a sheep; praying to unreliable gods; doing nothing at all; and of course, flying. Next come rafts of poems about making peace (or not) with the complicated bonds of friendship and family, and making peace (or not) with death, in the many ways it finds us. Some poems reflect on the redemptive powers of art and poetry itself; others consider where everything begins. Closing the book are poems that celebrate natural wonders--birdsong and ghost-flowers, ruthless ants, clever shellfish, coral reefs, deadly deserts, and thousand-year-old beech trees--all speaking to the daring project of belonging to an untamed world beyond ourselves.https://corescholar.libraries.wright.edu/dlpp_all/1668/thumbnail.jp

High Tide in Tucson: Essays from Now or Never

With the eyes of a scientist and the vision of a poet, Barbara Kingsolver writes about notions as diverse as modern motherhood, the history of private property, and the suspended citizenship of humans in the animal kingdom. Kingsolver\u27s canny pursuit of meaning from an inscrutable world compels us to find instructions for life in surprising places: a museum of atomic bomb relics, a West African voodoo love charm, an iconographic family of paper dolls, the ethics of a wild pig who persistently invades a garden, a battle of wills with a two-year-old, or a troop of oysters who observe high tide in the middle of Illinois.https://corescholar.libraries.wright.edu/dlpp_all/1278/thumbnail.jp
