The Impact

Selective logging is the predominant method of commercial timber exploitation in South East Asia. Its effects upon mammalian carnivores have seldom been addressed, despite the vulnerability of these animals at the top of many food chains. The authors investigated the effects of logging by comparing the abundance of sympatric civet species, which display feeding strategies ranging from strict carnivory tofrugivory, in primary and selectively logged rainforest in the Malaysian state ofSabah in northern Borneo. All species occurred in disturbed forest, but the overall density of civets in logged forest (6.4 individuals per sq km) was found to be significantly lower than in primary forest (31.5 individuals per sq km). This reflected a marked reduction in the abundance of civets from the predominantly carnivorous subfamilies Viverrinae and Hemigalinae.

Arthropod Abundance

Abstract:Deforestation rates in South-East Asia are among the highest of any tropical region, with expansion of oil palm being one important factor. Despite this, few studies have investigated the impact of oil palm expansion on the arthropod fauna. We report here the first study on the impact of forest conversion to oil palm on overall arthropod abundance, biomass and composition. We compared arthropod abundance and biomass, collected from epiphytic bird's nest ferns, the canopy, and leaf litter between primary forest, logged forest and oil palm plantation. Epiphytes, canopy and litter all contained a lower abundance (epiphytes: 67.2%, canopy: 2.3% and litter: 77.1% reduction) and biomass (epiphytes: 87.5%, canopy: 37.9% and litter: 72.4% reduction) of arthropods in oil palm compared with primary forest. However, not all orders of arthropods showed the same level of decline, with some groups having higher abundance and biomass in oil palm, resulting in an altered community composition in the epiphytes and canopy in oil palm compared with forest. Our results show that forest conversion to oil palm impacts detrimentally on invertebrates in all compartments of the forest ecosystem.

Lowland Dipterocarp Forest

In lowland dipterocarp forest in Sabah, Malaysia, most primary forest bird species were present in areas selectively logged eight years previously. However, certain taxa, notably flycatchers, woodpeckers, trogons and wren-babblers, became comparatively rare. In contrast, nectarivorous and opportunistic frugivorous species were significantly more abundant. Few species appeared to change foraging height, but netting rates suggest that the activity of some species had increased, or that some birds ranged over larger areas after logging. Although there is still much to be learned about the survival of birds in logged forest, large areas of this habitat are important for bird conservation. However, the susceptibility of logged forest to fire, and our present incomplete understanding of bird behaviour and population dynamics in logged forests mean that they should not be considered by conservationists as alternatives to reserves of primary forest.

We used traps baited with fruit to examine how the temporal variation of butterflies within primary forest in Sabah, Borneo differed between species. In addition, we compared patterns of temporal variation in primary and selectively logged forest, and we tested the hypothesis that selective logging has different recorded impacts on species diversity of adults during the wet monsoon period and the drier remaining half of the year. Species of Satyrinae and Morphinae had significantly less-restricted flight periods than did species of Nymphalinae and Charaxinae, which were sampled mainly during the drier season, especially in primary forest. Species diversity of adults was significantly higher during the drier season in primary forest, but did not differ between seasons in logged forest. As a consequence, logging had opposite recorded impacts on diversity during wetter and drier seasons: primary forest had significantly higher diversity than logged forest during the drier season but significantly lower diversity than logged forest during the wetter monsoon season. The results of this study have important implications for the assessment of biodiversity in tropical rain forests, particularly in relation to habitat disturbance: short-term assessments that do not take account of seasonal variation in abundance are likely to produce misleading results, even in regions where the seasonal variation in rainfall is not that great.

The Impact

Purpose Excessive working capital or paucity of the same can impair the profits and health of an organization. The purpose of this paper is to analyze the impact of working capital management (WCM) on the profitability of firms for a sample comprising of non-financial companies in countries of South East Asia, South Asia and East Asia. Design/methodology/approach Analytical modeling has been used to estimate the impact of WCM on profitability with the help of financial data of the companies listed in major indices of the target countries (India, Pakistan, Myanmar, Sri Lanka, Bangladesh, Singapore, Thailand, Malaysia, Indonesia, Vietnam, Hong Kong, Japan, China, South Korea and Taiwan). The mathematical model presented in the paper has been tested using two-step-generalized method of moments. Findings The study reveals a non-linear relationship between profitability of a firm and WCM for 11 economies of the Asia Pacific region. Research limitations/implications The results are subject to the differences in the market dynamics of different economies (countries). Moreover, the limitations of the specific statistical method used to verify the model apply to the model too. Practical implications The research can be used as a tool by the firms (global as well as local) to ameliorate their performance by understanding the effects of WCM on profitability in different global markets and adjusting their working capital accordingly. Originality/value The research on the impact of WCM on profitability of the firms of South East Asia, South Asia and East Asia is a new effort and tries to make the importance of WCM more luciferous.

Transition To Independence

Abstract The purpose of this paper is twofold. The first part examines trends in revenue policies across South East Asia in the early decades of the twentieth century. It is argued that, by the 1920s, there were quite striking differences in revenue policies and performance across the region. The paper examines the reasons for these differences, paying particular attention to the conflicting demands placed on the various colonial administrations by conditions within the colonies, as well as by the changing priorities of the metropolitan governments. The second aim of the paper is to examine the impact of the transition to independence on revenue policy and performance. It is often thought that in most parts of Asia, the advent of political independence led to a greatly expanded role for government in the economy. While it is true that many newly independent countries had ambitious plans for government as the lead actor in promoting rapid economic development, in fact in several countries in South East Asia, it proved very difficult to increase revenues in real terms. The reasons for this are explored in the paper.
