Abstract:: ... Smooth cordgrass, Spartina alterniflora, is a perennial grass species that forms distinctive colonies on mudflats. Such colonies can increase their size by expanding clonally to surrounding open mudflats and their number by establishing new colonies on far away from the original colonies either by sexual reproduction or rhizome fragmentation. In this work, we aimed to link colony dynamics mechanis ...

Abstract:: ... Semi-arid tropical rangelands substantially contribute to livelihoods of subsistence farmers, but are threatened by undesired vegetation shifts due to climate change and overgrazing. Grazing-induced shifts of the grass community composition are often associated with rangeland degradation. To identify sustainable management strategies, a process-based understanding of grass functional diversity and ...

Abstract:: ... When a matrix population model is nonautonomous, i.e., when represents a set of single-time-step ("annual") PPMs, L(t), t = 0, 1, …, T – 1, each corresponding to a fixed life cycle graph, then each of the annual matrices generates its own set of model results to characterize the population. In particular, λ1(t), the asymptotic growth rate, varies with t and may result in alternating predictions of ...

Abstract:: ... Demographic rates differ between populations and also fluctuate over time, sometimes driving large fitness differences, but the strength of stochastic effects remain heretofore unresolved. We demonstrate the importance of stochastic processes by comparing the drivers of long-term population growth. We quantify stochastic contributions to differences in population growth rates among 218 plant and t ...
