MotivationThe BioTIME database contains raw data on species identities and abundances in ecological assemblages through time. These data enable users to calculate temporal trends in biodiversity within and amongst assemblages using a broad range of metrics. BioTIME is being developed as a community‐led open‐source database of biodiversity time series. Our goal is to accelerate and facilitate quantitative analysis of temporal patterns of biodiversity in the Anthropocene.Main types of variables includedThe database contains 8,777,413 species abundance records, from assemblages consistently sampled for a minimum of 2 years, which need not necessarily be consecutive. In addition, the database contains metadata relating to sampling methodology and contextual information about each record.Spatial location and grainBioTIME is a global database of 547,161 unique sampling locations spanning the marine, freshwater and terrestrial realms. Grain size varies across datasets from 0.0000000158 km2 (158 cm2) to 100 km2 (1,000,000,000,000 cm2).Time period and grainBioTIME records span from 1874 to 2016. The minimal temporal grain across all datasets in BioTIME is a year.Major taxa and level of measurementBioTIME includes data from 44,440 species across the plant and animal kingdoms, ranging from plants, plankton and terrestrial invertebrates to small and large vertebrates.Software format.csv and .SQL.

A drastic increasing in Sea Surface Temperature (SST) was happened in Andaman Sea including in Aceh region from April through end of May 2010. The recent escalations of SST have caused mass coral bleaching event in many places in the world including northern Aceh water of Indonesia. Bleaching survey was conducted in Northern Aceh to measure ecological impact of bleaching including bleaching index, coral cover and reef fish abundance. More than 35% bleached coral were died, with tremendous mortality of susceptible genera such as Acropora and Pocillopora. Coral bleaching has impact in declining coral cover in Northern Aceh significantly after coral bleaching and the evidence of loss Acropora in some area. Coral bleaching also impact to coral fishes, where fishes abundance especially coralivorous fishes has declining significantly betwen 2009 and 2011 also 2013. The 2010 bleaching event is one of the most severe events reported for Indonesia including in Northern Aceh.

Increased sea surface temperatures due to global warming that occurred from the early to mid 2016 caused of coral bleaching in several locations in TWP Gili Matra. Observations of coral bleaching obtained from coral colonies compotition affected by bleaching (50%), white (18%), death (1%) and was not affected (31%). These implications resulting decline in coral cover but not significant (F (1,013) = 0.333, p > 0.05) from 23,43% ± 2,61 SE in 2012 to 18,48% ± 4,14 SE in 2016 and a significant decrease (P (58,06) (P(20,84)=0,00053,p<0,001) kelimpahan ikan karang dari 28.733,26 ind.ha -1 ± 3.757,89 SE di tahun 2012 menjadi 11.431,18 ind.ha -1 ± 702,53 SE di tahun 2016

This study aimed to fill the gap of knowledge on this group of fishes by estimating the natural stock, species composition and biodiversity of target reef fishes from three regencies; Alor, East Flores (Flores Timur) and Southwest Maluku (Maluku Barat Daya/MBD) using underwater visual census method. A total of 176 species belong to 19 families of economically important target fish were recorded from 62 survey sites. The highest estimated stock is located in Southwest Maluku Regency – based on both abundance and biomass values, followed by Alor Regency and the lowest in East Flores Regency. Target fish species from the family of Caesionidae has the highest composition both based on abundance (74%) and biomass (40%). The highest species composition of target fish is from Pterocaesio tile (57.65%) which is more than 50% of the overall target fish. Community structure of target fish in the three regencies is still in a relatively good condition based on diversity index (H’), evenness (E) and no domination (C) of a single species occurs inside the target fish community, with exception in Alor Regency where the community of target fish is indicated to be under pressure. Biodiversity index by Bray-Curtis analysis in each location shows that most of the sites have the similarity of 67.51%, suggesting that there is not much difference in terms of target fish community structure between the three regencies.
