AbstrakArea konservasi ex situ, Ecopark Cibinong Science Center-Botanic Gardens (CSC-BG), membutuhkan strategi pemeliharaan tanaman koleksi yang tepat untuk mendukung kesehatan dan keberlanjutan koleksinya. Serangan benalu atau tumbuhan parasit tidak hanya dapat merusak estetika, namun juga menghambat pertumbuhan dan perkembangan, bahkan membunuh tanaman koleksi. Penelitian ini bertujuan untuk mengetahui keanekaragaman jenis benalu dan distribusi spasial dari sebaran benalu di Ecopark CSC-BG. Pengumpulan spesimen dan data, meliputi jenis dan jumlah benalu, jenis dan kondisi inang, habitat menggunakan metode jelajah di seluruh area ini. Ditemukan empat jenis benalu dari suku Lorantaceae, yaitu Dendrophthoe pentandra (L.) Miq., Scurrula atropurpurea (Blume) Danser, Macrosolen cochinchinensis (Lour.) Tiegh., dan Dendrophthoe sp. Benalu tersebut tersebar di bioregion Blok 1, Jawa-Bali, Kalimantan, Sumatra, dan Papua. Beberapa faktor ekofisiologi yang disarankan untuk diperhatikan dalam distribusi benalu adalah tinggi inang, ekspos cahaya pada tajuk bagian atas inang, kepadatan tanaman koleksi, keterbukaan atau ekspos cahaya matahari pada habitat. Indeks keanekaragaman (H’) dan indeks kemerataan (E’) benalu yang ditemukan menunjukkan H’ = 1,29 dan E’ = 0,93. Hasil analisis pola spasial, keberadaan benalu relatif merata di seluruh bagian Ecopark CSC-BG, dengan keragaman jenis tertinggi berada di bioregion Jawa-Bali, Sumatra, dan Kalimantan. Kesimpulan penelitian ini 4 jenis benalu yang ditemukan di Ecopark CSC-BG dengan nilai indeks keanekaragaman jenis benalu tergolong sedang dengan pola sebaran merata.AbstractThe Ecopark Cibinong Science Center-Botanic Gardens (CSC-BG), requires the right collection of plant maintenance strategies to support the health and sustainability of the collection. Attack by parasites or parasitic plants can not only destroy aesthetics, but also inhibit growth and development, and even kill the collected plants. This study aims to determine the diversity of parasite types and the spatial distribution of the distribution of parasites in Ecopark CSC-BG. Collection of specimens and data, including the type and number of parasites, types, and conditions of the host, habitat using the roaming method throughout this area. Four types of parasites were found from the Loranthaceae tribe, namely Dendrophthoe pentandra (L.) Miq., Scurrula atropurpurea (Blume) Danser, Macrosolen cochinchinensis (Lour.) Tiegh., and Dendrophthoe sp. These types of parasites are scattered in the Block 1 bioregion, Java-Bali, Kalimantan, Sumatra, and Papua. Some of the recommended ecophysiological factors to consider in the distribution of mistletoes were host height, light exposure to the upper canopy of the host, plant collection density, openness, or exposure to sunlight in the habitat. The diversity index (H') and evenness index (E') of mistletoes found were 1.29 and 0.93, respectively. The results of spatial pattern analysis, the presence of mistletoes was relatively evenly distributed throughout the garden, with the highest species diversity found in the Java-Bali, Sumatra, and Kalimantan Bioregions. This study concludes that there were 4 species of mistletoes found in Ecopark CSC-BG with a moderate diversity index and an even distribution pattern.

Abstract. Hidayat S, Zuhud EAM, Widyatmoko D, Bahruni. 2021. Assessing the conservation value of medicinal plant collections in Bogor Botanic Gardens, Indonesia. Biodiversitas 22: 696-706.  Botanic gardens contain plant collections for the purpose primarily for ex-situ conservation, yet the public rarely appreciates these collections. As such, assessing the conservation value of botanic gardens collections is very important as an effort to increase public awareness of the importance of botanic gardens and their plant collections. This research aimed to assess the conservation value of plant collection in Bogor Botanic Gardens (BBG), Indonesia using quantitative and qualitative methods. We focused our assessment on medicinal plant collections with the habitus of tree. Conservation value of a plant collection was approached by preservation value and utilization value both quantitatively using monetary units and qualitatively using non-monetary index. Based on these two approaches, quantitatively most (91%) of the medicinal plant collections in BBG assessed in this study have a value of more than one million rupiahs, even 21% have a value of more than 100 million rupiahs, implying the high monetary value of medicinal plant collection in Bogor Botanic Gardens. Meanwhile, qualitatively, the conservation value score of a species will be strongly influenced by the existence of protection laws issued by the government and the cultural level of plants' use by the community. Our framework of assessing the conservation value of plant collections, especially those with medicinal purposes, can be replicated in other botanic gardens.

Abstract. Hartini S, Aprilianti P. 2020. Orchid exploration in Tanjung Peropa Wildlife Reserves for Kendari Botanic Gardens collection, Indonesia. Biodiversitas 21: 2244-2250. Tanjung Peropa Wildlife Reserve (Tanjung Peropa WR) is one of the conservation area in Southeast Sulawesi Province, Indonesia. The inventory of orchid in this area is still limited and Kendari Botanic Garden (Kendari BG) need to collect the orchids from this location. Orchid diversity inventory and exploration had been carried out on March 26- April 12, 2019, in Tanjung Peropa WR and collecting them as an ex-situ conservation effort in order to enrich Kendari BG plant collection. The specimen was collected by using explorative method at 5 locations in Tanjung Peropa WR. The result showed that there were 10 epiphytic orchids found of Aerides, Cymbidium, Dendrobium, Grammatophyllum, Liparis, Pomatocalpa, and Thrixspermum. Also, there were 5 terrestrial orchids of Corymborkis, Eulophia, Nervilia, Phaius, and Tropidia. The orchid species were found in the area between 25-110 m above sea level (asl), with temperature 27-31°C, humidity 75-80%, soil acidity 5.0-6.0, soil humidity 80-90%, and canopy dense between 60-80%. Kendari BG has collected 34 species of orchid from Southeast Sulawesi, with 25 species of epiphytic and 9 species of terrestrial orchids.

Introduction. It is rare for actinic or squamous cell carcinoma (SCC) in situ to metastasize. Case Presentation. A 67-year-old male had a significant medical history including severe psoriatic arthritis treated with UVB, methotrexate, and rapamycin. He had twenty-five different skin excisions of actinic keratosis four of which were invasive SCC. Our patient developed shortness of breath necessitating a visit to the emergency department. A CT scan of his chest revealed a mass in the right lower lung. A subsequent biopsy of the mass revealed well-differentiated SCC. He underwent thoracoscopic surgery with wedge resection of the lung lesion. Discussion. Actinic keratosis (AK) is considered precancerous and associated with UV exposure. It exists as a continuum of progression with low potential for malignancy. The majority of invasive SCCs are associated with malignant progression of AK, but only 5–10% of AKs will progress to malignant potential. Conclusion. In this case, a new finding of lung SCC in the setting of multiple invasive actinic cutaneous SCC associated with a history of extensive UV light exposure and immunosuppression supports a metastatic explanation for lung cancer.

Most activities are done outside the home often make the skin exposed to UV light. Exposure UV light excessively or in a long time can cause the occurrence of skin disorders such as Sunburn, premature aging, lowering skin immunity to skin cancer. In preventing the negative effects of UV light on the skin, various ways can be done such as by using a protector such as clothes, hats, glasses or umbrellas. But this physical protection is not sufficient because of the UV light penetrating power. Sunscreen is a skin care cosmetic that provides physical protection against UV light. Proper use of sunscreen and routine can protect the skin from the negative effects of UV light. This paper describes the effects of UV light on the skin, the function of sunscreen and the right use and compatible types sunscreen in maintaining skin health from the adverse effects of UV light.

Botanic gardens and arboreta offer the opportunity to conserve and manage a wide range of plant diversity ex situ, and in situ in the broader landscape. The rationale that botanic gardens have a major role to play in preventing plant species extinctions is based on the assumptions that (1) there is no technical reason why any plant species should become extinct, and (2) that, as a professional community, botanic gardens possess a unique set of skills that encompass finding, identifying, collecting, conserving and growing plant diversity across the entire taxonomic spectrum. Botanic Gardens Conservation International (BGCI) is the pivotal centre of a global network of c. 2,600 botanic gardens and arboreta, which includes living collections representing at least one-third of known plant diversity; world class seed banks, glasshouses and tissue culture infrastructures; and technical knowledge networks covering all aspects of plant conservation. Following the example of the crop conservation community, BGCI is promoting the concept of a cost-effective, rational,botanic garden-centred Global System for the conservation and management of plant diversity.This system will aim to collect, conserve, characterise and cultivate samples from all of the world’s rare and threatened plants as an insurance policy against their extinction in the wild and as a source of plant material for human innovation, adaptation and resilience.

We tested whether evening exposure to unilateral photic stimulation has repercussions on interhemispheric EEG asymmetries during wakefulness and later sleep. Because light exerts an alerting response in humans, which correlates with a decrease in waking EEG theta/alpha-activity and a reduction in sleep EEG delta activity, we hypothesized that EEG activity in these frequency bands show interhemispheric asymmetries after unilateral bright light (1,500 lux) exposure. A 2-h hemi-field light exposure acutely suppressed occipital EEG alpha activity in the ipsilateral hemisphere activated by light. Subjects felt more alert during bright light than dim light, an effect that was significantly more pronounced during activation of the right than the left visual cortex. During subsequent sleep, occipital EEG activity in the delta and theta range was significantly reduced after activation of the right visual cortex but not after stimulation of the left visual cortex. Furthermore, hemivisual field light exposure was able to shift the left predominance in occipital spindle EEG activity toward the stimulated hemisphere. Time course analysis revealed that this spindle shift remained significant during the first two sleep cycles. Our results reflect rather a hemispheric asymmetry in the alerting action of light than a use-dependent recovery function of sleep in response to the visual stimulation during prior waking. However, the observed shift in the spindle hemispheric dominance in the occipital cortex may still represent subtle local use-dependent recovery functions during sleep in a frequency range different from the delta range.

Abstract Biodiversity of zooplankton is central to the functioning of ocean ecosystems, yet morphological taxonomic analysis requires teams of experts and detailed examination of many samples. Metabarcoding (DNA sequencing of short amplified regions of one or a few genes from environmental samples) is a powerful tool for analysis of the composition and diversity of natural communities. The 18S rRNA V9 hypervariable region was sequenced for 26 zooplankton samples collected from the Gulf of Maine, Georges Bank, and Mid-Atlantic Bight during ecosystem monitoring surveys by the U.S. Northeast Fisheries Science Center during 2002–2012. A total of 7 648 033 sequences and 22 072 operational taxonomic units (OTUs) were identified and classified into 28 taxonomic groups of plankton. Comparative analysis of molecular (V9 sequence numbers) and morphological (abundance counts) focused on seven taxonomic groups and revealed similar patterns of variation among years and regions. Sequence numbers and abundance counts showed positive correlation for all groups, with significant correlations (p < 0.05) for Calanoida, Gastropoda, and Chaetognatha. Shannon diversity index values calculated using sequence numbers and abundance counts showed highly significant correlation (r = 0.625; p < 0.001) across all regions during 2002–2012. This study demonstrates the potential of metabarcoding for time-series analysis of zooplankton biodiversity, ocean ecosystem assessment, and fisheries management.

AbstractOver the last few decades botanic gardens worldwide have been encouraged to adopt complementary measures for the conservation of plant species from their own regions, combining in situ conservation efforts with ex situ methods, both in cultivation and in storage. This integrated approach is particularly important for botanic gardens in the tropics, which face the challenge of conserving a highly diverse and often threatened flora. We gathered information on the occurrence of threatened species in the natural vegetation reserves of 21 Brazilian botanic gardens. The data were collected from herbarium records in the database of the National Centre for Flora Conservation, and from the available plant inventories of these reserves. The results indicate that 148 species from the List of Threatened Species of Brazilian Flora are recorded as having been collected in the reserves. Of these, 51 species were maintained in the living collections of 18 botanic gardens and 83 species were recorded in federally protected areas. The occurrence of threatened species in the reserves of botanic gardens highlights the scientific value of these areas, as well as their biological, social and cultural importance for conservation. The results may be used to inform the planning of integrated conservation strategies for threatened species.

Kenya lies within sorghum centre of diversity. However, information on the relative extent of diversity patterns within and among genetically defined groups of distinct ecosystems is lacking. The objective was to assess the structure and phenotypic diversity of wild sorghum populations across a range of geographical and ecological conditions in the country. Sixty-two wild sorghum populations (30 individuals per population) sampled from four distinct sorghum growing regions of Kenya and covering different agroecologies were characterized for ten qualitative traits. Plant height, number of tillers, panicle sizes and flag leaf dimensions were also recorded. Frequencies of the phenotypic classes of each character were calculated. The Shannon diversity index (H′) was used to estimate the magnitude of diversity. Principal component analysis was used to differentiate populations within and between regions. Wild sorghum is widely distributed in Kenya, occurring in sympatric ranges with cultivated sorghum, and both have overlapping flowering windows. All characters considered displayed great phenotypic diversity. Pooled over characters within regions, the mean H′ ranged between 0.60 and 0.93 in Western and Coast regions, respectively. Wild sorghum was found to show a weak regional differentiation, probably reflecting the importance of seed-mediated gene flow in shaping the wild sorghum population structure. Trait distribution was variable among regions, but there was no conspicuous distribution of the traits studied in any given region. Spontaneous hybridization and introgression of genes from cultivated to wild sorghum seems to be likely, and may already have occurred for a long time, although undocumented. Implications for in situ and ex situ genetic resources conservation are discussed.
