Melichrus

You will conduct analyses (r studio) and write a report addressing the following topic.
Melichrus R.Br. is an Australian endemic genus of shrubs in the heather family, Ericaceae. There are currently six accepted species in the genus that have been described on the basis of morphological differences, four of which have broad distributions in eastern Australia. Morphological variability within those species (M. adpressus, M. urceolatus, M. erubescens and M. procumbens) suggest that there may be unrecognised species of Melichrus that will be revealed through integration of molecular and morphological methods. The two newest species, M. hirsutus and M. gibberagee, have very narrow distributions and appear to meet the criteria for conservation listing. If undiscovered species are also narrow endemics, they are unlikely to receive the protection they deserve unless they are recognised as distinct evolutionary lineages.
PhD student Helen Kennedy is revising the taxonomy of Melichrus using an integrative approach. They include a subset of her data focusing on populations that key out to four related species, with metadata describing their sampling locations and field determinations. With this data, you are to address the following questions:
1. Does molecular evidence support the current taxonomy? Which species are supported and which are not?
2. Are there distinctive genetic groups that may require description as new taxa?
3. Is there evidence of inbreeding, and does it represent a threat to any accepted or putative taxa?
4. Is there evidence of hybridisation, and does it represent a threat to any accepted or putative taxa?

 

 

Sample Solution 

Section I: INTRODUCTION TO THE STUDY Introduction The country is encountering a basic deficiency of medical care suppliers, a lack that is supposed to increment in the following five years, similarly as the biggest populace in our country’s set of experiences arrives at the age when expanded clinical consideration is vital (Pike, 2002). Staffing of emergency clinics, facilities, and nursing homes is more basic than any time in recent memory as the huge quantities of ‘gen X-ers’ start to understand the requirement for more continuous clinical mediation and long haul care. Interest in turning into a medical caretaker has disappeared lately, likely because of the historical backdrop of the extraordinary and requesting instructive cycle, low compensation, firm and extended periods of time, and fast ‘wear out’ of those rehearsing in the calling (Wharrad, 2003).

A complex oversaw care climate in this country is restricting the dollars accessible to be spent on nursing care. Numerous wellbeing callings, particularly nursing, have the standing of ‘eating their young’ as opposed to offering compelling coaching to develop future medical services suppliers. Because of these variables, the quantity of medical attendants has diminished and businesses regard themselves as understaffed and seeking able work force. Before 2001 the decay had been apparent for a considerable length of time (Sadler, 2003). Nursing schools, public pioneers, medical services pioneers and the overall population is impacted by the absence of Registered Nurses (RNs) accessible.

As the populace ages, the assumption is that a rising number of RNs will be required essentially to keep up with the ongoing degree of medical care. Furthermore, the momentum ecological and political worries of expanding pandemic sickness, event of synthetic and catastrophic events, and expanding dangers of war, requires critical expansions in the medical services labor force (Jefferys, 2001). The public nursing lack and factors that increment the interest for expanding the nursing labor force notwithstanding public, state, and nearby debacles make the potential for a general wellbeing emergency. Nursing programs have endeavored to satisfy need for medical attendants by expanding enlistment and campaigning effectively for expansions in program subsidizing by schools and states for understudies.

Tragically, the issue of nursing understudy weakening hampers the best endeavors of nursing programs and irritates the public lack of Registered Nurses in the United States (Ofori, 2002). In 2003, the National League for Nursing revealed a positive vertical pattern in the nursing labor force supply in any case, the American College of Healthcare Executives (2006) detailed that in 2005, 85% of emergency clinic directors decided medical clinics needed more enlisted medical attendants to fulfill patient consideration needs. The United States Bureau of Labor insights showed by 2014, more than 1.2 million new and substitution nursing positions would be expected to meet the public medical services needs (Ramsburg, 2007).

Various broad endeavors to diminish weakening have been made by nursing programs including reinforcing affirmation methods and executing maintenance programs. Unfortunately, the issues of weakening keep on continuing nursing schools the nation over. Admission to a nursing program is serious and numerous potential understudies are denied confirmation every semester. Steady loss from nursing programs influences not just the particular understudy who is acknowledged to a nursing program and ineffective, yet in addition the understudy denied confirmation that might have been effective. Steady loss rates are expensive to understudies, nursing projects, and medical services the same by diminishing the quantity of likely alumni from schools of nursing and adding to the nursing lack. Many examinations feature the a lot higher than wanted whittling down rates for nursing understudies
