Curiosity about environmental changes drives Dr Katlego Mashiane’s PhD research

In the small village of Ga-Mabotia about 25 km outside of Polokwane, Dr Katlego Mashiane grew up, surrounded by rocky mountains characterised by boulder outcrops, where he interacted with nature from an early age.

He recently obtained his PhD, majoring in Geography, from the University of the Free State (UFS), which was conferred on him during the April graduation ceremonies that took place on the UFS Qwaqwa Campus. The title of his dissertation is Grass nutrients estimation as an Indicator of rangeland quality using satellite remote.

Predicting the presence of biodiversity and nutrients in an area

Based on the principle that diverse grasslands tend to perform better, environmental changes threaten the resilience and services these grassland ecosystems provide. The study examined how many different types of plants and animals can be found at a particular place to enhance our understanding of the ecosystem’s value to humans, and that biodiversity loss will reduce these ecosystem services. Focusing on spatial modelling of grassland diversity, Dr Mashiane specifically investigated the influence of topography and remotely sensed satellite data on species richness and diversity in subalpine environments, and how they are affected by the availability of grass species. To determine this, he used a random forest machine-learning algorithm to find the best information in the data that could be used to estimate the levels of species richness, diversity, and nitrogen in a protected national conservation park.

His study discovered that some data types – such as the near-infrared variable and certain vegetation data (EVI and SAVI) – were especially useful for determining the number and variety of species in a certain area. With this information, scientists can create models that predict the presence of different types of biodiversity and nutrients in an area.

Playing a key role in protecting our natural assets

Equipped with this knowledge, one will be able to understand how to protect and preserve different types of biodiversity and promote the nutritional value of both plants and animals in the environment. “Land managers could use this information for conservation strategies,” states Dr Mashiane, who decided to pursue this study because he was curious about how environmental changes will affect species.

“Grasslands provide important ecosystem services underpinning human well-being, and therefore warrant our protection; I would like to play a role in protecting our natural assets and contribute to understanding our biomes, especially in the context of global change,” he says.

In the next five years, Dr Mashiane plans to pursue further research and mentor other students in his field of study.

OSM opening concert 2012

2012-03-02

The OSM Camerata is going to shine in the very first annual OSM opening concert.
1 March 2012

OSM opening concert 2012 with the OSM Camerata
Conductor: Nicholas Nikolaidis
Date: 1 March 2012
Venue: Odeion
Time: 19:30

The OSM opening concert 2012 with the OSM CAMERATA will be streamed live on the internet with the generous support of OSM partner, LA MUSE AUDIO & LIGHTING (www.ufs.ac.za/ufslivestreaming) in collaboration with the UFS LIVE STREAMING UNIT.

The OSM Camerata is going to shine in the very first annual OSM opening concert. The ensemble will be conducted by Nicholas Nikolaidis. The programme includes excerpts from Stabat Mater (Pergolesi), Romanian Folk Dances (Bartók), Pelimannit (Rautavaara), Elegy (Grové) and Purple Haze (Hendrix). since 2011, the Odeion School of Music has embarked on a new, innovative strategy striving towards uncompromising excellence and internationalisation, which includes the A-List scholarship programme and a new flagship chamber ensemble, the OSM Camerata. Talented South African, conductor/tenor Nicholas Nicolaidis, (runner-up in the First National Len van Zyl Orchestral Conducting Competition) will take the stage for the inaugural concert of the OSM.

Nicholas started his conducting career at an early age while still in the Drakensberg Boys’ Choir School. Professionally his first conducting post was as choirmaster and conductor of the choir and band at Pridwin Preparatory School (Melrose, Johannesburg) in 1996.

Following his appointment in April 1997 as the Musical Director of Côr Meibion Cymru de Affrig (The Welsh Male Voice Choir of South Africa), he conducted the choir for seven years, producing three albums. One of the highlights was the performance at the Royal Albert Hall in London in October 2000 for the Millennium Festival of Male Voice Choirs.

His orchestral conducting debut was in 1998 at the Johannesburg City Hall where he conducted the Johannesburg Festival Orchestra and the Symphony Choir of Johannesburg in a few items of ‘Last Night of the Proms’. Selected conducting performances include the Chanticleer Singers in a performance of Schubert’s Mass in G at the Holy Trinity Church (Braamfontein, Johannesburg) in 2002, and the Johannesburg Camerata, a chamber orchestra consisting of talented young performers, during their winter season in 2005.

In 2006, Nicholas enrolled at Stellenbosch University for a Master’s degree in Choral Conducting under the direction of the Norwegian pedagogue, Kåre Hanken. During this time, he also conducted the Johannesburg-based chamber choir, Collegium Vocale. He conducted the Johannesburg Chamber Wind Ensemble from 2006 to 2008.

In 2009, he conducted the Johannesburg Festival Orchestra in a programme of music by Leroy Anderson, the vocal ensemble, In Verse, and the Chanticleer Singers during their Christmas season. Nicholas was also the winner of the inaugural Young Choral Conductors Competition held during the Stellenbosch International Choral Conducting Symposium in March 2009.

In February 2010, he was awarded the Silver Medal in the inaugural Len van Zyl Conducting Competition held in conjunction with the Cape Philharmonic Orchestra. During the Easter period of 2010 he conducted Cantamus Corde in a performance of JS Bach’s St John’s Passion, whilst also singing the role of the Evangelist.

Nicholas has also appeared as guest conductor of the Philharmonia Choir of Cape Town in a concert with music by Ramirez and Klatzow. In that year he also conducted the gala Concert of the Brooklyn Theatre (Pretoria).

Refreshments will be on sale before and after the concert.
