the global avian invasions atlas a database of alien bird distributions worldwide
Scientific Data, 2017Co-Authors: Ellie E Dyer, David W Redding, Tim M BlackburnAbstract:The introduction of species to locations where they do not naturally occur (termed aliens) can have far-reaching and unpredictable environmental and economic consequences. Therefore there is a strong incentive to stem the tide of alien species introduction and spread. In order to identify broad patterns and processes of alien invasions, a spatially referenced, global dataset on the historical introductions and alien distributions of a complete taxonomic group is required. Here we present the Global Avian Invasions Atlas (Gavia)—a new spatial and temporal dataset comprising 27,723 distribution records for 971 alien bird species introduced to 230 countries and administrative areas spanning the period 6000BCE—AD2014. Gavia was initiated to provide a unified database of records on alien bird introductions, incorporating records from all stages of invasion, including introductions that have failed as well as those that have succeeded. Gavia represents the most comprehensive resource on the global distribution of alien species in any major taxon, allowing the spatial and temporal dynamics of alien bird distributions to be examined.

EKSPRESI RANKL PASCA PEMBERIAN SCAFFOLD HIDROKSIAPATIT DARI CANGKANG KEPITING (Portunus pelagicus) PADA SOKET PASCA PENCABUTAN GIGI MARMUT (Cavia cobaya)
2019Co-Authors: Agam Wirayudha 021618076306Abstract:Latar Belakang: Mempertahankan alveolar ridge pada saat pencabutan adalah hal yang penting. Preservasi soket merupakan suatu prosedur yang bertujuan mengurangi kehilangan tulang setelah pencabutan gigi. Salah satu jenis material alloplast yang sering digunakan adalah scaffold. Salah satu komponen penyusun tulang yang paling mempengaruhi adalah RANKL. Adanya penurunan jumlah RANKL berarti semakin sedikit osteoclas yang aktif dan diharapkan osteoblas tumbuh lebih banyak untuk membentuk matriks tulang. Tujuan: Untuk menganalisis ekspresi RANKL dengan pemberian scaffold hidroksiapatit dari cangkang kepiting (Portunus pelagicus) pada soket pasca pencabutan gigi marmut (Cavia cobaya) pada hari ke-7 dan ke-14. Material dan Metode: 24 ekor Cavia cobaya yang dibagi menjadi empat kelompok, gigi insisivus kiri rahang bawah dicabut kemudian dilakukan preservasi soket. Kelompok I, setelah Cavia cobaya dicabut giginya, soket pencabutan tanpa diberi perlakuan. Setelah 7 hari diterminasi, kemudian diperiksa. Kelompok II, setelah Cavia cobaya dicabut giginya, soket pencabutan tanpa diberi perlakuan. Setelah 14 hari diterminasi kemudian diperiksa. Kelompok III, setelah Cavia cobaya dicabut giginya, soket pencabutan diberi scaffold hidroksiapatit dari cangkang kepiting (Portunus pelagicus), setelah 7 hari diterminasi kemudian diperiksa. Kelompok IV, setelah Cavia cobaya dicabut giginya, soket pencabutan diberi scaffold hidroksiapatit dari cangkang kepiting (Portunus pelagicus), setelah 14 hari diterminasi kemudian diperiksa. Data penelitian dianalisis menggunakan One Way Anova dan Tukey HSD. Hasil: Terdapat perbedaan signifikan antara kelompok kontrol dengan kelompok yang diberi scaffold hidroksiapatit dari cangkang kepiting (Portunus pelagicus). Kelompok IV adalah kelompok yang mempunyai jumlah RANKL terendah. Kesimpulan: Pemberian scaffold hidroksiapatit dari cangkang kepiting (Portunus pelagicus) pada soket pasca pencabutan gigi pada marmut (Cavia cobaya) dapat menurunkan ekspresi RANKL

Genomic insights into natural selection in the common loon (Gavia immer): evidence for aquatic adaptation
BMC Evolutionary Biology, 2018Co-Authors: Zach G. Gayk, Diana Le Duc, Jeffrey Horn, Alec R. LindsayAbstract:Background The common loon ( Gavia immer ) is one of five species that comprise the avian order Gaviiformes. Loons are specialized divers, reaching depths up to 60 m while staying submerged for intervals up to three minutes. In this study we used comparative genomics to investigate the genetic basis of the common loon adaptations to its ecological niche. We used Illumina short read DNA sequence data from a female bird to produce a draft assembly of the common loon ( Gavia immer ) genome. Results We identified 14,169 common loon genes, which based on well-resolved avian genomes, represent approximately 80.7% of common loon genes. Evolutionary analyses between common loon and Adelie penguin ( Pygoscelis adeliae ), red-throated loon ( Gavia stellata ), chicken ( Gallus gallus ), northern fulmar ( Fulmarus glacialis ), and rock pigeon ( Columba livia ) show 164 positively selected genes in common and red-throated loons. These genes were enriched for a number of protein classes, including those involved in muscle tissue development, immunoglobulin function, hemoglobin iron binding, G-protein coupled receptors, and ATP metabolism. Conclusions Signatures of positive selection in these areas suggest the genus Gavia may have adapted for underwater diving by modulating their oxidative and metabolic pathways. While more research is required, these adaptations likely result in (1) compensations in oxygen respiration and energetic metabolism, (2) low-light visual acuity, and (3) elevated solute exchange. This work represents the first effort to understand the genomic adaptations of the common loon as well as other Gavia and may have implications for subsequent studies that target particular genes for loon population genetic, ecological or conservation studies.

EKSPRESI TRANSFORMING GROWTH FACTOR-β1 (TGF-β1) PASCA PEMBERIAN SCAFFOLD HIDROKSIAPATIT DARI CANGKANG KEPITING (PORTUNUS PELAGICUS) PADA SOKET PENCABUTAN GIGI CAVIA COBAYA
2019Co-Authors: Satrio Krestiono Maharmardoyo 021618076301Abstract:Latar Belakang: Proses pencabutan gigi akan diikuti proses resorbsi dan regenerasi yang merupakan proses penyembuhan secara fisiologis, namun seringkali menimbulkan berubahan bentuk ridge. Preservasi soket pencabutan menggunakan bone graft adalah salah satu cara meminimalisir resorpsi dan memaksimalkan proses pembentukan tulang. TGF β-1 adalah marker pembentukan tulang. Peningkatan ekspresi TGF β-1 menandakan peningkatan pembentukan tulang. Pemberian scaffold hidroksiapatit dari cangkang kepiting (Portunus pelagicus) yang memiliki sifat osteokonduksi diharapkan dapat meningkatkan ekspresi TGF β-1 Tujuan: untuk menganalisis peningkatan ekspresi TGF β-1 pada soket pencabutan gigi yang diberi scaffold hidroksiapatit dari cangkang kepiting (Portunus pelagicus). Material dan Metode: 24 ekor Cavia cobaya yang dibagi menjadi empat kelompok, gigi insisivus kiri bawah dicabut kemudian dilakukan preservasi soket. Kelompok pertama adalah kelompok kontrol tanpa perlakuan pada soket pencabutan hari ke-7, kelompok kedua diberi scaffold hidroksiapatit dari cangkang kepiting (Portunus pelagicus) hari ke-7, kelompok ketiga kelompok kontrol tanpa perlakuan hari ke -14, dan kelompok keempat diberi scaffold hidroksiapatit dari cangkang kepiting (Portunus pelagicus) hari ke-14. Pada hari ke-7 dan 14, Cavia cobaya diterminasi dan diperiksa dengan tehnik imunohistokimia. Data penelitian dianalisis menggunakan One Way Anova dan Tukey HSD. Hasil: Pada hari ke-7, kelompok yang diberi hidroksiapatit dari cangkang kepiting (Portunus pelagicus) menunjukkan peningkatan ekspresi TGF β-1 yang signifikan dibanding kelompok kontrol. Kesimpulan: Pemberian scaffold hidroksiapatit dari cangkang kepiting (Portunus pelagicus) mampu meningkatkan ekspresi TGF β-1 pada soket pencabutan Cavia cobaya
