Examples of Müllerian mimicry, in which resemblance between unpalatable species confers mutual benefit, are rare in vertebrates. Strong comparative evidence for mimicry is found when the colour and pattern of a single species closely resemble several different model species simultaneously in different geographical regions. Todemonstrate this, it is(More)
The study of Amazonian biodiversity requires detailed knowledge of the phylogenetic relationships of closely related taxa distributed across Amazonia. The Amazonian poison frogs of the genus Dendrobates have undergone many taxonomic revisions, but the phylogenetic relationships within this group remain poorly understood. Most previous classifications were(More)
PURPOSE To evaluate potential prognostic factors for local control and survival after radiotherapy of metastatic spinal cord compression (MSCC). PATIENTS AND METHODS The following potential prognostic factors were investigated retrospectively in 1,852 patients irradiated for MSCC: age, sex, performance status, primary tumor, interval between tumor(More)
Amazonia is famous for high biodiversity, and the highlands of the transition zone between the Andes and the lowlands of the Amazon basin show particularly high species diversity. Hypotheses proposed to explain the high levels of diversity in the highlands include repeated parapatric speciation across ecological gradients spanning the transition zone,(More)
PURPOSE To identify significant prognostic factors after irradiation of metastatic spinal cord compression (MSCC) in 335 breast cancer patients. METHODS AND MATERIALS The potential prognostic factors investigated included involved vertebra, other bone metastases, visceral metastases, performance status, pretreatment ambulatory status, time until motor(More)
PURPOSE Patients with prostate cancer with metastatic spinal cord compression have better survival prognosis than other patients with MSCC and may live long enough to develop a local recurrence of MSCC. This study investigates prognostic factors and radiation schedules for functional outcome and local control of MSCC after radiotherapy in patients with(More)
PURPOSE To study five radiotherapy (RT) schedules and potential prognostic factors for functional outcome in metastatic spinal cord compression (MSCC). PATIENTS AND METHODS One thousand three hundred four patients who were irradiated from January 1992 to December 2003 were included in this retrospective review. The schedules of 1 x 8 Gy in 1 day (n =(More)
OBJECTIVE For MSCC treatment, a short treatment time is desirable, especially if survival prognosis is poor. Survival depends on the primary tumor, extent of disease, performance status, ambulatory status, and the number of involved vertebrae. These factors may help to define the appropriate regimen for the individual patient. Our study compares(More)
PURPOSE To investigate the suitability of short-course radiotherapy (RT) for spinal cord compression (SCC) in myeloma patients. METHODS AND MATERIALS Data for 172 myeloma patients irradiated between January 1994 and December 2004 for SCC were retrospectively evaluated. Short-course RT (1 x 8 Gy, 5 x 4 Gy, n = 61) and long-course RT (10 x 3 Gy, 15 x 2.5(More)
