Abstract: Abstract. Latifah D, Congdon RA, Holtum JA. 2017. Population structure of palms in cyclone-dependent rainforests. Bio ersitas 18: 41-50.Tropical cyclones may act as important ecological drivers in northern Australia including north Queensland, as several cyclones impact this region each year between November and May. Extensive research has been conducted to investigate how the population structure of rainforest species respond to cyclonic disturbances. However, there have been few such studies on palms although they are important components of rainforests. Therefore, these study aimed to investigate how the population structure of Arenga australasica (H. Wendl. & Drude) S. T. Blake ex H. E. Moore, Calamus australis Mart., C. moti F. M. Bailey, Hydriastele wendlandiana (F. Muell.) H. Wendl. & Drude and Licuala ramsayi var. ramsayi (F. Muell.) H. Wendl. & Drude responded to a cyclone, as shown by size class reflecting mass recruitment after a periodic major disturbance (case study: Cyclone Larry). The field research was carried out in three study sites: Tam OShanter/Djiru National Park, Clump Mountain National Park and Kurrimine Beach Conservation Park located near Mission Beach and Kurrimine Beach, in north Queensland. Observations were made of life stage distribution, height and dbh distribution and wind resistance. We found that responses of the population structures of these rainforest palms varied following cyclonic disturbance by demonstrating higher densities of seedlings and juveniles, suggesting populations would be retained. More seedlings of C. australis and C. moti were found in gaps with higher canopy openness oppositely, less seedlings of L. ramsayi were encountered under sites with lower sunlight. Keywords: disturbance, palms, population structure, northern Australia

Abstract: Indonesian bio ersity including the rich flora is facing various threats, including deforestation, habitat degradation, fire, natural disasters and climate change. Many ex situ conservation strategies have been implemented in response to this problem, including the development of new local botanic gardens in each province throughout Indonesia. The purpose of this paper is to reveal the important role of seed banks in forming part of the botanic gardens’ collections management strategies – they now play an increasingly important role in saving the Indonesian flora from extinction. This study was conducted by undertaking a literature review and analysis of secondary data on the four largest botanic gardens of Indonesia. Currently there are 33 botanic gardens in Indonesia consisting of five national botanic gardens under Lembaga Ilmu Pengetahuan Indonesia (LIPI/Indonesian Institute of Sciences), two botanic gardens under universities and 26 botanic gardens managed by Local Goverments. Among the five national botanic gardens, four manage seed banks: the Seed Bank of the Center for Plant Conservation Botanic Gardens/Bogor Botanic Gardens banks 749 accessions covering 460 species, 305 genera and 114 families Cibodas Botanic Garden Seed Bank has 61 accessions covering 57 species, 57 genera, 40 families Purwodadi Botanic Garden Seed Bank has 413 accessions covering 207 species, 134 genera and 46 families and Eka Karya Bali Botanic Garden Seed Bank maintains 132 accessions covering 89 species, 43 genera and 21 families. The Indonesian Botanic Garden Seed Banks thus hold 1,355 accessions in total, covering less than 1% of total Indonesian plant ersity. In order to increase this coverage, Indonesian seed banking capacity needs to be increased, through the technical development of existing seed banks and the engagement of local botanic gardens throughout Indonesia to establish mini seed banks using the community seed bank approach.

Abstract: Abstract. Widjaya AH, Latifah D, Hardwick KA, Suhartanto MR, Palupi ER. 2021. Reproductive biology of Vatica venulosa Blume (Dipterocarpaceae). Bio ersitas 22: 4327-4337. Vatica venulosa Blume is categorized as Critically Endangered A1c ver 2.3, according to the IUCN Red List. A study of the reproductive biology of V. venulosa Blume was carried out in August 2019-February 2020 at the Research Center for Plant Conservation and Botanic Gardens, Bogor, Indonesia. The research observed flower morphology, flower development, type of pollination, fruit and seed structures. V. venulosa is categorized as having a sub-annual flowering pattern. The flowering phenology of V. venulosa from flower bud emergence until fruit senescence takes about 6 months. The flower is hermaphroditic, with position of the pistil is higher/longer than the stamen and pollen was released prior to stigma being receptive (protandrous). V. venulosa is a cross-pollinated plant, the flower visitors are insect nymphs of Thrips sp. (Thysanoptera: Thripidae), which are white and 1-1.5 mm in size. The percentage of blooming flowers was 32.3-37.9%, fruit set 10.9 %-12.6%. Seed physiological maturity is reached at the age of 101±3-106±3 days after the flowers bloom when the wings are yellow green or green orange in color. V. venulosa seed is a non endospermous seed, and the cotyledons are composed mainly of small clumps of starch, being 42.5% carbohydrate.
