Despite widespread support from policy makers, funding agencies, and scientific journals, academic researchers rarely make their research data available to others. At the same time, data sharing in research is attributed a vast potential for scientific progress. It allows the reproducibility of study results and the reuse of old data for new research questions. Based on a systematic review of 98 scholarly papers and an empirical survey among 603 secondary data users, we develop a conceptual framework that explains the process of data sharing from the primary researcher’s point of view. We show that this process can be divided into six descriptive categories: Data donor, research organization, research community, norms, data infrastructure, and data recipients. Drawing from our findings, we discuss theoretical implications regarding knowledge creation and dissemination as well as research policy measures to foster academic collaboration. We conclude that research data cannot be regarded a knowledge commons, but research policies that better incentivize data sharing are needed to improve the quality of research results and foster scientific progress.

What Drives Academic Data Sharing

Taking the pulse of Earth's tropical forests using networks of highly distributed plots

While attention to logging in the tropics has been increasing, studies on the long-term effects of silviculture on forest dynamics and ecology remain scare and spatially limited Indeed, most of our knowledge on tropical forests arise from studies carried out in undisturbed tropical forests This bias is problematic given that logged and disturbed tropical forests are covering now a larger area than the so-called primary forests The Tropical managed Forests Observatory (TmFO), a new network of permanent sample plots in logged forests, aims to fill this gap by providing unprecedented opportunities to examine long-term data on the resilience of logged tropical forests at regional and global scales TmFO currently includes 24 experimental sites distributed across three tropical regions, with a total of 536 pem1anent plots and about 1200 ha of forest inventories In this paper we will present the main results generated by the network on the impact of logging on Carbon and timber recovery, as well as biodiversity changes in the Amazon basin and South East Asia

The Cikaniki resort is one of the most accessible research stations located in the Gunung Halimun Salak National Park (GHSNP). It is in adjacent with Citalahab village. The Research Center for Biology, Indonesian Institute of Sciences and other institutions have conducted intensive research on the fauna diversity of GHSNP from this station. Here we formulate a checklist on fauna diversity surrounding the Cikaniki Research Station and Citalahab, GHNSP from various sources, i.e. field work, museum collections (Museum Zoologicum Bogoriense), scientific publications, and technical report. The study was conducted from October 2019 until October 2020. The latest field work was conducted from 8-10 October 2019 under the framework of the Jungle Survival and Biological Collection Management 2019 program. In total, 821 fauna species were recorded in Cikaniki-Citalahab areas which comprises of 48 species of Mollusca, five species of Malacostraca, 523 species of Insects, 22 species of Actinopterygii, 63 species of Amphibia and Reptiles, 115 species of Aves and 45 species of Mammals. The diversity contributes 62.1% of the total 1,323 known fauna species in GHSNP. Five number of species were assigned as endangered and three species critical endangered by IUCN. In addition, 123 species were endemic to Java and 34 species protected by Regulation of the Ministry of Environment and Forestry Republic of Indonesia Number P.106/MENLHK/SETJEN/KUM.1/12/2018. The areas of Cikaniki and Citalahab are rich in biodiversity. Although both areas are in close intact with human activity, research and ecotourism, the need of continuously spreading awareness and enforce species and area conservation is inevitable.

CHECKLIST ON FAUNA DIVERSITY GUNUNG HALIMUN SALAK NATIONAL PARK: Cikaniki-Citalahab

SADILI, A. & KARTAWINATA, K. 2016. A study of the undergrowth vegetation of Sempu Island, East Java, Indonesia. Reinwardtia 15(1): 1 - 9. — A study of forest floor vegetation in coastal forest (site 1) and inland lowland forest (site 2) was carried out at the Sempu Island Nature Reserve, Malang Regency, East Java. The objective of the study is to obtain data on plant species diversity, species composition and structure of the forest floor vegetation. In each site the vegetation was sampled with a plot of 1 m × 50 m, which was divided into 50 subplots of 1 m × 1 m each. Overall from the two plots we recorded 59 species, 57 genera and 39 families. Shannon-Wienner diversity indices (H’) were relatively high. i.e., 4.47 in Plot 1 and 3.2 in Plot 2, with a mean of 3.84. The number of the seedlings of shrubs and trees was greater than that of the herbaceous species. The families having the highest number of species were Euphorbiaceae (6 species) and Fabaceae (5 species). Based on dominant species the vegetation in Plot 1 was designated as Scleria lithosperma-Asystasia nemorum community type, while in Plot 2 Pterospermum javanicum-Knema sp. community type. The similarity index between these community types was only 18%. Only P. javanicum  showed a good regeneration and the regeneration of other species in the two community types was poor, indicating unclear floristic changes in the forest of the Sempu Island.

First year re-monitoring conducted in 2009 through measuring the entire individuals that have been given numbersand giving new numbers to individuals with stem diameter more than 5 cm. The result of re-monitoring indicatesthat the numbers of populations and species increased, but not significant. Mortality rate observed 7 individualsper hectare (about 1.20 %); whereas natality rate observed 25 individuals per hectare (about 2.52 %), which isregarded as low. Basal area observed in 2008 was approximately 26.55 m2 per hectare and it increased to about27.34 m2 per hectare in 2009. Total number of individuals in 2009 was 595 individuals from 119 species, 86genera, and 44 families with diversity index of 3.60 (Hâ€™). Elaeocarpus petiolatus (Elaeocarpaceae) and Planchoniavalida (Sapotaceae) are new additions. Altingia excelsa is still the dominant species.Keywords: Forest dynamics, rasamala permanent plots, Bodogol, GPNP

A quantitative study of epiphytic plants was conducted at the logged over forest in Kiyu, Meratus Mountain, Hulu Sungai Tengah, South Kalimantan. This study used a plot of 10 m x 500 m (± 0,5 ha), and divided into 50 subplot of 10 m x 10 m. The results showed that there were nine species of six genera from three families of epiphytic plants found within the studied plot, with A grostophyllum bicuspidatum as the dominant species. The diversity index (H’) was of 1,85. The diversity of epiphytic plant in these plots was well represented based on the results of analysis of species area curve. Spatial distribution pattern of all epiphytic species was homogeneus, except for A. bicuspidatum. The number of epiphytic host plants observed was 22 individuals from six species of six genera, and five families, with Saurauia nudiflora (Acthiniaceae) was the dominant host plant.

Galunggung Mountain forest area in West Java of post eruption 1982 may served as a natural laboratory for studying plant development and plant growth, including pine trees. Pine trees that were planted by Perhutani at Galunggung had high prospect although they were planted at degraded areas and poor nutrient. Experimental plots were set up in two different locations at Mount Galunggung. Trunk diameter, tree height, total height, soil humidity and soil pH was measured for all pine trees inside the plot at each subplot. All measured parameters resulted in varied values with varied deviation standard. Measurement of trunk diameter, branches height and total height of pine trees in Mount Galunggung suggested that their growth rate was slow and no significant correlation among them.

An analysis of the composition and structure of lowland natural forests was carried out in Bodogol, Gunung Gede Pangrango National Park (GGPNP). The two study plots (P1CS and P2CS) were located on Cisuren and one plot (P3CP) on Cipadaranten hill. We recorded 107 species and 48 families with an average basal area of 19.73 m2/ha, and an average density of 348 trees/ha. The species richness was poorer than those of the typical lowland rainforests of Kalimantan and Sumatra but comparable to those of the montane forests of Java. The IUCN-Red Listed species were Castanopsis argentea and Castanopsis tungurrut (critical) and Saurauia bracteosa (vulnerable). Based on the two dominant species, the forests can be designated as the Maesopsis eminii-Syzygium acuminatissimum association and Syzygium acuminatissimum-Lithocarpus korthalsii association. Maesopsis eminii was dominant in P1CS (IV= 56.46%) and P3CP (IV=55.94%), while Syzygium acuminatissimum in P2CS (IV= 43.67%). Maesopsis eminii was a strongly aggressive and invasive species, that endangered the purity of the natural forest GGPNP, therefore, it must be eradicated. Vertically, P2CS and P3CP consisted of four strata, while P1CS had three strata. This one-hectare study can be considered as a minimal area to reflect the floristic representation of lowland forest and submontane forest.
