Prey spectra of bornean nepenthes species (Nepenthaceae) in relation to their habitat
Examination ofpitcher prey contents of 18 Bomean pitcher plants showed that pitchers attract 17 fauna groups.
The upper and lower pitchers trap both flying and creeping fauna but generally the lower pitchers trap more
creeping fauna and upper pitchers more flying prey species. Prey composition is generally correlated with habitat;
species occupying different habitats in the same locality sometimes show striking differences in prey composition.
Formicidae are the most abundant and frequently trapped, and pitchers collected below 100 m altitude contained
enormous numbers of ants but their number generally decreased with altitude. However, the number of ants
caught per pitcher was variable, e.g. from a few ants to 700 per pitcher in N. rafflesiana. Nepenthes species
growing at high altitudes trapped a broader spectrum ofprey than species at lower altitudes. This broad spectrum
of prey provides an ample food source for the pitcher-inhabiting predators, particularly Arachnida, which are
common in high altitude species
Palynological study of Bornean Nepenthes (Nepenthaceae)
Palynological study shows that the mean pollen tetrad size of 27 Bornean Nepenthes species ranges from 27Um
to 38.9 Um, thus falling into the small and medium-sized grain class. Aperture type, exine sculpturing, pollen
unit and shape are homogeneous among Bornean species and thus not taxonomically useful at the specific and
sectional level. The mean pollen tetrad size revealed that the species under investigation can be divided into three
groups: Group 1: 27 Um, Group 11:28.5-34.7 Um, and Group IIl:37.2-38.9 Um

Two species of pitcher plants namely Nepenthes gracilis Korthals and . mirablis (Loureiro) Druce were recorded in the plot with an area of 0.1 hectare. The former species differed from the later species lJy its angular stem, sessile leaves, very thin peristome (~ 1 mm thick), under surface of pitcher lids were sparsely glandular, inner
surface of the pitcher cavities were partly covered with exposed type of digestive glands whereas the later species
have cylindrical stem, petiolate leaves, thick peristome (;? 1 mm thick), under surface of pitcher lids were densely
glandular, inner surface surface of the pitcher cavities were partly covered with overarched type of digestive glands. The population density of N. gracilis is greater than that of N. mirabalis, each contained 147 and 15
individuals respectively. The low density of the former species was attributed to its strong tendency to grow in wet
soil particularly in temporary and permanent inundated secondary vegetation. The population dispersion pattern
of seedlings, saplings and matured plants of N. gacilis and N. gracilis were significantly aggregated
Rafflesia tunku-azizahiae (Rafflesiaceae), a new species from Pahang, Malaysia
A new species of Rafflesia (Rafflesiaceae) from Mt. Benom Forest Reserve, Ulu Dong, Raub, Pahang, Rafflesia tunku-azizahiae Adam, Aizat-Juhari & Wan is described and illustrated. Cluster analysis and principal component analysis showed that R. tunku-azizahiae and R. tuanku-halimii are closely related morphologically, characterized by perigone lobes covered by rows of very closely spaced coalesced white warts, and windows wholly covered by very closely rings of coalesced white warts. Score plot and bi-plot showed that R. tunku-azizahiae differs from R. tuanku-halimii by larger flower diameter, broader diaphragm and disc diameter, larger aperture diameter and longer ramenta

Ekopelancongan dan analisis sosioekonomi komuniti Ulu Dong
Lata Jarum terletak di Daerah Raub, Pahang merupakan sebuah destinasi ekopelancongan yang dapat menarik
pelancong dengan keindahan hutan semulajadi yang kaya dengan khazanah flora dan fauna. Ekopelancongan ialah
pelancongan yang memberi impak minimum serta menyumbang kepada pengekalan habitat dan spesies hidupan
secara langsung dan tidak langsung termasuklah pengekalan kebudayaan masyarakat tempatan di samping dapat
meningkatkan taraf sosioekonomi mereka. Projek ekopelancongan Lata Jarum dapat menyediakan pelbagai peluang
pekerjaan kepada komuniti setempat. Mereka berpeluang mengusahakan pelbagai jenis perniagaan seperti chalet,
produk makanan tradisional, projek pertanian, perubatan berasaskan herba atau sebagai pemandu pelancong dan
pengawal hutan. Penduduk setempat perlu memahami konsep ekopelancongan serta berusaha untuk melibatkan diri
dalam projek eko-pelancongan. Komuniti setempat bakal menerima kesan pembangunan sama ada secara langsung
atau tidak langsung. Makalah ini bertujuan menganalisis sosioekonomi penduduk setempat di Mukim Ulu Dong.
Kajiselidik dan temubual dilakukan terhadap informan utama iaitu penduduk di tiga buah perkampungan Melayu
dan sebuah kampung Orang Asli di Mukim Ulu Dong. Kajian mendapati, majoriti komuniti di Mukim Ulu Dong
bekerja sendiri dengan memperolehi pendapatan sebulan kurang daripada RM1000. Kaum belia kebanyakan
mempunyai taraf pendidikan yang rendah. Walau bagaimanapun, terdapat juga komuniti yang terlibat dalam
perusahaan IKS seperti perniagaan kedai runcit, pembuatan kraftangan, pertanian, pengeluaran produk makanan dan
perusahaan chalet namun bilangannya masih kecil. Penglibatan komuniti amat penting untuk menjadikan mereka
lebih aktif dan efektif di samping dapat meningkatkan kesediaan komuniti untuk turut mencari peluang pekerjaan
dalam bidang ekopelancongan
Potensi pelancongan di Matu-Daro, Sarawak: persepsi komuniti lokal
Industri pelancongan merupakan salah satu industri yang menyumbang kepada ekonomi negara dan
pembangunan setempat. Pembangunan pelancongan di sesebuah kawasan memberikan impak positif terhadap
komuniti lokal itu sendiri menerusi penglibatan secara langsung dan tidak langsung iaitu dapat meningkatkan
kualiti hidup serta kesejahteraan masyarakat. Justeru itu, pengenalpastian potensi pelancongan di sesebuah
kawasan dapat membantu mewujudkan pelbagai peluang pembangunan menerusi industri pelancongan di
kawasan tersebut. Kajian ini bertujuan untuk mengenal pasti persepsi komuniti lokal Melanau mengenai potensi
pelancongan di kawasan Matu-Daro, Sarawak. Kaedah tinjauan melalui temubual berdasarkan satu set kaji
selidik terhadap 150 orang responden di daerah Matu-Daro. Hasil kajian mendapati tiga jenis pelancongan yang
berpotensi di perkembangkan iaitu pelancongan warisan dan kebudayaan, agro-pelancongan dan
ekopelancongan. Potensi pelancongan warisan dan kebudayaan boleh diperkembangkan dengan adanya Rumah
Panjang Melanau Islam yang tertua di dunia, Makam Orang Kaya Segunim, dan Pesta Kaul. Seterusnya agropelancongan
menerusi pengusahaan pembuatan sagu dan penanaman padi yang dijalankan secara tradisional.
Ekopelancongan juga boleh diketengahkan iaitu keunikan kawasan hutan paya bakau dan menyelami nilai
estetika di Sungai Rajang. Secara kesimpulannya, Daerah Matu-Daro mempunyai potensi untuk dikomersilkan
menerusi sektor pelancongan
