Diversity and Abundance of Some Insect Fauna in Krau Wildlife Reserve Forest, Malaysia.

31.10.2012
Concerned about habitat changes due to logging and rapid development, Universiti Teknologi MARA researchers recently conducted a study on the diversity of the important Hymenoptera group, which includes bees, wasps and ants. Their results will be useful in forest conservation programmes.

This study was initiated due to the changes taking place to the natural habitat of insects due to logging and development. These activities pose a great threat to insect communities in the forest.

The study focused on Hymenoptera known as the most important group of insects in any terrestrial ecosystem. Bees, wasps and ants are some of the insects in this group. They are important pollinators of flowering plants as well as predators of many arthropods. As such, many of them can be classified as the key stone species in a particular ecosystem.

Preliminary observation showed that the Hymenopteran were quite diverse at the Krau Wildlife and Forest Reserve (KWFR), Pahang, geographically considered as a lowland dipterocarp forest, which is connected to the Malaysian National Park. The objective of this study was to determine the level of biodiversity, abundance and richness of Hymenoptera in Kuala Lompat, Krau Wildlife Forest Reserve and to study its relationship, if any, between changes in environmental gradient from forest fringes and deeper into the forest.

The findings of this study indicated that certain species of insects were found in abundance along the fringes of the forest where many species of flowering plants were found. However, closed and narrow areas deeper in the forest with many trees, shrubs and grass provided shelter for the insects from predators for example birds and therefore constituted a higher diversity of Hemiptera compared to those found at the forest fringes or along the river which is more open and exposed to predators.

In conclusion, the study area in KWFR forest, Kuala Lompat recorded 1236 specimens and 55 morphospecies of insects under order Orthoptera, Hemiptera and Diptera. For Orthoptera and Diptera, forest fringes recorded the highest abundance while for Hemiptera, the most abundant individuals were found in the interior of the forest. Orthoptera, Hemiptera and Diptera could be used as a bio indicator in Malaysian forest because their ease in identification process and well known taxonomic. This method is useful and should be used by ecologist in forest conservation program.

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.

But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...

Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.

The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...

Im Focus: Autonomous 3D scanner supports individual manufacturing processes

Let’s say the armrest is broken in your vintage car. As things stand, you would need a lot of luck and persistence to find the right spare part. But in the world of Industrie 4.0 and production with batch sizes of one, you can simply scan the armrest and print it out. This is made possible by the first ever 3D scanner capable of working autonomously and in real time. The autonomous scanning system will be on display at the Hannover Messe Preview on February 6 and at the Hannover Messe proper from April 23 to 27, 2018 (Hall 6, Booth A30).

Part of the charm of vintage cars is that they stopped making them long ago, so it is special when you do see one out on the roads. If something breaks or...
