Dominant Grasses, Not Subordinate Forbs, Sustain Ecosystem Multifunctionality Across Spatial ScalesNARA Subscribed
Anthropogenic nitrogen (N) deposition and shifts in plant functional composition can alter grassland biodiversity and ecosystem functioning, yet their interactive effects on multifunctionality across spatial scales remain poorly understood. Using an eight‐year field experiment that combined plant functional group removal with N addition in a subalpine meadow, we tested how N addition and the removal of dominant grasses or subo...
Despite extensive research on life-extending interventions, rigorous statistical techniques to determine their impact on compression of morbidity (CoM) are rarely used. We present a case example of an analytical method for examining the effect of life-extending dietary interventions on CoM by comparing the rates of decline in vitality and survival toward the end of life. Using data from previous experimental studies in mice, w...
Extensive Population Structure Highlights an Apparent Paradox of Stasis in the Impala ( Aepyceros melampus )NARA Subscribed
Impalas are unusual among bovids because they have remained morphologically similar over millions of years—a phenomenon referred to as evolutionary stasis. Here, we sequenced 119 whole genomes from the two extant subspecies of impala, the common ( Aepyceros melampus melampus ) and black‐faced ( A. m. petersi ) impala. We investigated the evolutionary forces working within the species to explore how they might be associated wit...
Escape of genetically distinct farmed Atlantic salmon ( Salmo salar ) raises concerns about their potential interactions with wild populations and the disruption of local adaptation through genetic admixture. It is often unknown whether genetic origin or common domestication effects will have a greater influence on consequences posed by escaped farmed fish. Previous work showed that domestication could have prevalent effects o...
