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.

Im Focus: Nanoparticles help with malaria diagnosis – new rapid test in development

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.

Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
