Neolithic Culture

 A neolithic occupation in Kalimantan is marked by an open space near the water source and biodiversity which are potential for cultivation. Other characteristics of a neolithic occupation are the presence of archaeological items that suggest a sedentary lifestyle such as pottery, stone adzes, bark-cloth-beaters, and an indication of the arrival of the Austronesia-language-speaking people. Of the sites examined so far, there are two sites indicating open occupations in the southern slope of the Müller Mountains from around 3000-2000 years ago, the Nanga Balang and Muolo Joloi. Both sites are practically located in the heart of Kalimantan in the dense interior of the tropical rainforest. This research discusses the characteristic of Neolithic culture in Nanga Balang and MuaraJoloi to understand their variabilities. The research method used here is descriptive-comparative approach. The result of this research provides information on human strategies in interacting with the natural environment of the tropical rainforest.Keywords: Kalimantan, tropical rainforests, Neolithic occupation, radiocarbon dating, occupation characteristic, human survival.Okupasi neolitik di Kalimantan ditandai oleh ruang terbuka dekat sumber air dan keanekaragaman hayati yang potensial untuk perladangan. Karakteristik lain dari okupasi neolitik adalah keberadaan benda-benda arkeologi yang menunjukkan gaya hidup menetap seperti tembikar, adu batu, pemukul kulit kayu, dan indikasi kedatangan orang-orang berbahasa Austronesia. Dari situs yang diteliti sejauh ini, ada dua situs yang menunjukkan okupasi terbuka di lereng selatan Pegunungan Müller dari sekitar 3000-2000 tahun yang lalu, Nanga Balang dan Muara Joloi. Kedua lokasi tersebut praktis terletak di jantung Kalimantan di pedalaman hutan hujan tropis yang lebat. Penelitian ini membahas karakteristik budaya neolitik di Nanga Balang dan Muara Joloi untuk memahami variasinya. Metode penelitian yang digunakan di sini adalah pendekatan deskriptif-komparatif. Hasil penelitian ini memberikan informasi tentang strategi manusia dalam berinteraksi dengan lingkungan alam hutan hujan tropis pada masa lalu.Kata kunci: Kalimantan, hutan hujan tropis, okupasi neolitik, pertanggalan radiokarbon, karakteristik okupasi, kelangsungan hidup manusia

Abstract The southern Appalachian Mountains in eastern North America host exceptional diversity, a substantial proportion of which has been generated in place. Yet, beyond broad generalities, bio- and phylogeographical patterns, and the temporal scale of diversification in the region are poorly resolved. Using one mitochondrial and one nuclear marker, we analyze intraspecific diversity patterns in a flightless, litter-inhabiting rove beetle Dasycerus carolinensis Horn. Our goals were to reconstruct the phylogeographical history of this species, producing a dated intraspecific phylogeny, and to examine previous hypotheses of possible cryptic divergence across populations of the species. Samples derive from a mix of old-growth fragments and secondary growth forests, and we also ask whether old-growth remnants host a larger proportion of genetic diversity in the species. We recover a strong primary subdivision among major lineages across the French Broad River basin (dated to ~5.8 MYBP), and a secondary subdivision among western populations dating to ~4.5 MYBP. Most interpopulation uncorrected divergences exceed 5%, strongly suggesting cryptic differentiation. Old-growth populations do not show greater genetic diversity than secondary-growth populations, indicating that most populations have persisted through recent anthropogenic disturbance.

Representative Area

AbstractKumbira Forest is the best representative area of Angola's Central Escarpment and the only site known to hold significant populations of four of the five threatened endemic bird species of this habitat. However, the forest is disappearing as a result of human activities. Remote-sensing techniques were used to assess changes in forest cover, and bird and habitat surveys were performed to assess the effect of land-use changes on endemic species and the bird community. No relationships could be established between the presence of endemics and habitat and landscape variables. This lack of effect may be attributable to the low number of records and compounded by the mosaic structure of the landscape. Although forest cover has been maintained in Kumbira, old-growth forest has been replaced by secondary growth in many areas. Nevertheless these secondary-growth forest patches can maintain a bird community similar to that found in old-growth forest.
