Exploring rock fissures: does a specialized root morphology explain endemism on granite outcrops?
Our results are consistent with earlier work, indicating that species restricted to different types of drought-prone shallow-soil communities have undergone similar selection pressures. Although adaptive in their own habitat in terms of obtaining access to fissures in the underlying rock, these root system traits are likely to be maladaptive in deeper soil habitats. Therefore, our results may provide an explanation for the narrow endemism of many shallow-soil endemics.
The presenting symptoms and signs of female urethral diverticula are often diverse and easily overlooked. High suspicion of this disorder, detailed history-taking and physical examination are essential for detecting urethral diverticulum in females.
