Article: Adaptability of white jabon (Anthocephalus cadamba miq.) seedlings from 12 populations to drought and waterlogging

Abstract

The study was carried out for investigat ion of the adaptability of white jabon seedlings from 12 populations to drought and water logging stresses in a controlled green house. The results showed that the adaptive responses of white jabon seedling to drought and waterlogging stress eswere affected by genotype (population). The drought and waterlogging stresses significantly inhibited plant growth, biomass accumulation and allocation, leaf area, also decreased chlorophyll content, increased carotenoids contents and accumulated free proline. Relative water content and specific leaf area tended to be higher in waterlogging and declined in drought stresses. The result clearly indicated that white jabon seedlings were more adaptive to waterlogging than to drought stresses. Moreover, there were different responses to drought and waterlogging stresses between the twelve populations. Kampar, Gowa, Kuala Kencana and OKI populations exhibited higher growth performance and stress tolerance index to be adapted to waterlogging stress, while Gowa, Pomalaa and Kampar population had relatively better growth performance in the drought stress.

Article: Closely related and sympatric but not all the same: genetic variation of Indo-West Pacific Rhizophora mangroves across the Malay Peninsula

Abstract
Members of the mangrove genus Rhizophora represent the most commonly occurring and highly valued species in the Indo-West Pacific region. However, to date, few studies have been directed towards the understanding of their genetic variation. The levels and patterns of genetic variation at chloroplast and nuclear gene regions were studied in R. apiculata, R. mucronata, and R. stylosa sampled from Southeast Asia and Japan. All three species were characterized by low intraspecific genetic variation and a deficiency of heterozygotes in populations within the region, consistent with findings in studies on other mangrove species. Rhizophora mucronata and R. stylosa were also found to be more closely related than any of them with R. apiculata. During the Last Glacial Maximum, sea levels dropped to 120 m below the current levels, exposing part of the Sunda Shelf that became a barrier that limited gene flow between marine species living in the Pacific and Indian Oceans. Today, the Malay Peninsula is thought to still serve as a barrier to gene flow between populations occurring on its coasts. The pattern of genetic differentiation of R. apiculata supports the hypothesis of the land barrier effect of the Malay Peninsula, but such patterns were not found in R. mucronata and R. stylosa. Our findings suggest that R. apiculata, R. mucronata, and R. stylosa have different demographic histories despite being closely related and having sympatric distributions today. Furthermore, all three species appear to have high levels of inbreeding due to limited pollen and propagule dispersal, and that both these factors contributed to population differentiation.

Article: Population genetics of the critically endangered species Dipterocarpus littoralis (bl.) Kurz (dipterocarpaceae) endemic on nusakambangan island, Indonesia.

Abstract

Dipterocarpus littoralis Blume is a critically endangered dipterocarp species found only in Nusakambangan Island, Central Java, Indonesia. Patterns of genetic diversity and population genetic structure of adults and saplings in two extant populations (Kali Jati and Solok Besek) were estimated using ten microsatellite markers. A total of 39 alleles were found, with two and four alleles being unique in adult and sapling populations, respectively. Allelic richness and heterozygosity were similar between adult (Ar = 3.00; He= 0.423) and sapling (Ar = 3.25; He= 0.441) populations. Inbreeding coefficients in saplings were positive in both populations and statistically significant in Kali Jati, while those in adult populations were not significantly different from zero, indicating excessive inbreeding and selfing in the sapling populations. Genetic differentiation of the sapling populations (FST= 0.036) was slightly lower than in the adult populations (0.050), but only significantly so for saplings. This study revealed that D. littoralis has low genetic diversity in both adults and saplings. Similarly low values in allele richness and heterozygosity suggest that reductions of population size have been ongoing for long periods in this species. Significant genetic differentiation between sapling populations but not adult populations indicates that recent fragmentation is further accelerating the isolation process.

Article: An entrepreneurial, research-based university model focused on intellectual property management for economic development in emerging economies: The case of Bogor Agricultural University, Indonesia

Abstract
Higher education institutions in emerging regions of the world are increasingly expected (largely by their governments and community) to promote regional economic development and national competitiveness. This case study on one of the prominent academic universities in Indonesia – Bogor Agricultural University (Institut Pertanian Bogor, IPB) – highlights its successes and lessons learned in managing intellectual property as an entrepreneurial research-based university. This analysis of IPB provides general and specific insights for university administrators, researchers, and policy makers, especially in emerging economies, on appropriate strategies and measures in promoting synergies between research, entrepreneurialism and technology commercialization. The model provides strategies to maximize university research outputs, knowledge transfer and innovation to empower regional communities, and promote strategic and transformational partnerships, private sector engagement and economic growth opportunities for both the institution and the region.
