Recent advances in allometric theory have proposed a novel quantitative framework by which to view the evolution of plant form and function. This general theory has placed strong emphasis on the importance of long-distance transport in shaping the evolution of many attributes of plant form and function. Specifically, it is hypothesized that with the evolutionary increase in plant size natural s...

Under stressful circumstances, seed size has important consequences for germination, survival, and reproductive success; all of these are important components of plant fitness. This study investigates the relationship between seed size and fitness in the Sonoran Desert winter annual Dithyrea californica. This species represents a unique opportunity to study natural selection on seed size in the...

Intraspecific variation in the physiological characteristics of plant organs due to differences in genotype, environmental heterogeneity, or developmental stage is a generally accepted phenomenon, whereas plant size is much less recognised by ecophysiologists as an important source of phenotypic variation. This review argues that sizerelated intraspecific variability may be found in most plants...

Studies of the effects of patch size and isolation on plant species density have yielded contrasting results. However, much of the available evidence comes from relatively recent anthropogenic forest fragments which have not reached equilibrium between extinction and immigration. This is a critical issue because the theory clearly states that only when equilibrium has been reached can the numbe...

Introduction: Plant galls are insect-induced tumor-like growths of plant tissue which nourish and protect developing gall former larvae (1). Gall inducers are typically host specific (2). The morphology of galls produced is unique to each gall former species and reflects the expression of both insect and host plant genomes (3). For each species of gall inducer, gall size at maturity varies wide...

the aim of this study was to evaluate the effectiveness of individual-focused stress management training namely deep breathing exercise (dbe) on self-perceived occupational stress among male automotive assembly-line workers.a quasi-experimental study was conducted at 2 automotive assembly plants in malaysia over 9 months, from january 2012 to september 2012. assembly-line workers from plant a r...
