A permanent 1 ha (100 m × 100 m) plot with 25 subplots (quadrates) and 5 level rows ofaltitudinal difference was established for long-term monitoring of plant diversity and dynamicsin a tropical mountain forest of Pohen Mountain, Batukahu Nature Reserve, Bali, Indonesia.Enumeration of all tree species > 10 cm DBH (diameter at breast height) yielded a total of notless than 300 individuals that belonged to 24 species and 19 families with Podocarpaceae wasthe most abundant family in the forest. Plant density varied from 10-20 individuals/quadrates(20 m × 20 m). Species composition and diversity varied between each quadrates in a rowwithin the 1 ha plot. Third row (intermediate altitude) exhibits the highest species diversitywhereas the fifth row (the highest altitude) had the lowest species diversity. Ordinationanalysis showed that species composition in the first, second and third rows are differentwith species composition in the fourth and fifth row. Most of the pioneer tree species exhibitedclumped distribution over the plot. This study provides baseline information for themanagement and restoration on the tropical mountain forests of Pohen Mountain, BatukahuNature Reserve post wildfire in 1994.

Mount Merapi with its Merapi-type pyroclastic flows provides burnt and unburnt areas which are excellent to study establishment events of pioneer plant species. Using site comparison approach, floristic composition was studied, and thus one area that was burnt by pyroclastic flows in 2010 (Kalikuning) and one area that is relatively intact or unburnt (Kaliurang) was chosen as study sites. We found 7,817 individuals belonging to 72 species and 36 families in the burnt site, and 4,093 individuals belonging to 79 species and 39 families in the unburnt site. The most important family as determined by the Family Importance Value (FIV) was Rubiaceae in Kalikuning and Asteraceae in Kaliurang. In terms of Importance Value Index (IVI), Borreria occimoides (Rubiaceae) and Eupatorium riparium (Asteraceae) were the most important species in Kalikuning and Kaliurang, respectively. Multivariate approach using Non-metric Multidimensional Scaling ordination technique showed that floristic composition in the newly burnt site were different with those that occupying the intact site (RANOSIM = 0.72). Borreria occimoides, Eupatorium riparium, Athyrium dilatatum, Paspalum conjugatum, Brachiaria reptans and Selaginella doederleinii were the species mainly responsible in explaining the differences between sites.

Google Scholar sangat membantu para peneliti dalam hal literature searching. Selain itu paper yang sudah didapatkan bisa langsung di import referensinya ke beberapa reference manager seperti EndNote program sehingga tanpa perlu lagi manual menginput ke database Endnote. Referencing made easy.
Ditambah lagi, peneliti bisa punya akun di my citations, mengumpulkan naskah-naskah yang pernah kita publish dan melihat apakah ada penulis lain yang menggunakan paper kita sebagai reference di paper mereka. Terlihat di grafik bar sudah berapa paper yang di kutip dan berapa paper yang mengutipnya. Dengan demikian networking antar peneliti pun menjadi semakin mudah.

SPECIES RICHNESS ESTIMATION OF GROUNDOVER VEGETATION IN SOME PARTS OF 2010 PYROCLASTIC FLOWS AREAS OF MT. MERAPI USING EstimateS
Limited attention has been paid to the recovery of groundcover vegetation after eruption of a volcano. Species richness of groundcover plant communities in Kalikuning area of
was investigated one year after 2010 eruption. Species richness was described
with species-accumulation curves. Different species richness estimators were calculated
using EstimateS and used to
extrapolate species richness beyond the data collected. Species-accumulation
curve reached saturation as the number of sample increased. Observed species
richness was 72 species in Kalikuning area. Based on estimators, species
richness was higher than observed, estimated between 81 to 104 species. The
Bootstrap richness estimator was considered most appropriate to predict the
number of species at the study site if sampling were continued. Mount Merapi
