Simple tutorial on how to construct phylogenetic tree (NJ and MP) in MEGA 4 software

This is a simple tutorial, step by step on how to use MEGA file to construct phylogenetic tree (NJ and MP) in MEGA 4 software. To follow these simple steps, you will need to have a ‘MEG file’. I will explain on how to analyse your sequence and how to convert the data into ‘MEG file’ later.

1. Launch the MEGA 4 software
2. Click at ‘click me to activate data file’ or you can click ‘file’ then ‘open data’, or press F5.
3. Choose a data file to analyse, then click ‘open’.
4. MEGA 4 will show you ‘M4: Input Data’, then choose ‘data type’, then click ‘OK’.
5. MEGA 4 will show you ‘confirm’ the click ’Yes’. After that select the genetic code, and then click ‘OK’.


6. You will see a window as picture below. From here, you can try to explore the button at the top of the window, C (conserve sites), V (variable sites), Pi (parsimony informative sites), S (singleton sites) etc… then close the window and back to main MEGA 4 window.

7. to construct a phylogenetic tree (NJ), click ‘phylogeny’, then click ‘bootstrap test of phylogeny’, then click ‘neighbor-joining’.
8. MEGA 4 will show you ‘M4: Analysis Preferences’. Change model to Kimura-2-parameter. Then click ‘Compute’.


9. MEGA 4 will show you the results as below, try to explore and repeat Step 7 for MP tree analysis. Good luck!

Simple tutorial on how to use PAST programme (how to find the diversity indices)

I will show you the basic step on how to use PAST programme (Version 2.05) to calculate and find the diversity indices such as Shannon, Simpson, Menhinick, Margalef and Fisher alpha.

a. How to key in the data in Microsoft Excel:
 1. Open Microsoft Excel.
2. Column B, C, D, E, F (row 1): List of sampling sites
3. Row 2, 3, 4, 5, 6 (Column A): List of species present at the sampling sites
4. Column B till column F, Row 2 till Row 6: Number of individuals per species caught at each sampling sites


b. How to insert data in PAST
1. highlight data in the Microsoft Excel, then click ‘copy’.
2. open the PAST programme.
3. click at ‘Edit labels’
4. click ‘Edit’, then click ‘paste’. Or you can just use the shorcut (Ctrl+v).


5. after that, highlight the area, then click ‘diversity’ then click ‘diversity indices’.


6.  then PAST will show you ‘diversity’. Now, you can choose the diversity indices that you want. Good luck!

Simple tutorial on how to use Multivariate Statistical Package (MVSP) version 3.2

I will show you the basic step on how to use MVSP programme to calculate and find the species similarity index.

a. How to key in the data in Microsoft Excel:
1. Open Microsoft Excel
2. Column B, C, D, E, F (row 1): List of sampling sites
3. Column A, Row 2, 3, 4, 5, 6: List of species present at the sampling sites
4. Column B till column F, Row 2 till Row 6: number of individuals per species caught at each sampling sites



b. How to insert data in MVSP
1. open the MVSP programme.
2. click ‘file’, then click ‘import.’
3. select the Microsoft Excel file.
4. then MVSP will show you ‘Import preview’, if it is the correct file, click ‘OK’
5. then MVSP will show you ‘Currently open file’. If the variable and sample shown is correct, proceed to the next step.
6. click ‘Analyses’, then click ‘Cluster analysis…
7. then MVSP will show you ‘Cluster Analysis Option’. Choose appropriate ‘method’ and ‘measurement’, then click ‘OK’.
8.  MVSP will show you the result as below. Good luck!

Proboscis Monkey @ Monyet Belanda, Bako National Park, Sarawak

Scientific name: Nasalis larvatus
Common name: Proboscis monkey/ Monyet Belanda (Malay)

Proboscis monkey is endemic to Borneo. This endangered species show a high degree of sexual dimorphism. The body size of the males is usually larger than the females. The males also have a large protruding nose and this characteristic could distinguish between the males and the females of Proboscis monkey. This species lives in a group (called as harem) of 10 to 30 individuals comprises of one adults male and several females (with their young).
In Sarawak, Malaysia, this species can be found in Bako National Park (one of the smallest and the oldest national park in Malaysia, gazetted as protected area on 1957). There are seven types of forest in Bako National Park (beach, cliff, kerangas, mangrove, mixed dipterocarp, grassland and peat swamp).
What is the conservation status of Proboscis monkey? It is listed as endangered species in IUCN 2010 and listed in CITES Apendix I. Source: Meijaard, E., Nijman, V. & Supriatna, J. 2008.
