East Nusa Tenggara located in the Wallacea area that has many endemic species. However, the existence of germplasm diversity in this area has been threatened due to landscape changes and deforestation. The research was conducted to identify floristic composition in Sikka forest area. This research also aimed to compare that plant composition in Sikka forest area on each of the different altitudes, including their diversity richness and environmental factors. Two sampling methods were used, which are Point-Centered Quarter (PCQ) method that applied for trees and nested sampling method 5x5 m2 for sapling and 2x2 m2 for ground cover. Measured parameters were Relative Density (RD), Relative Frequency (RF), Relative Coverage/dominance (RC), Important Value Index (IVI), Diversity Index (H'), and Jaccard Similarity Index (J’). Research results showed that the diversity index of each region was relatively low. Plant composition of tree, sapling, and groundcover in three different altitudes was quite different. This result indicates that the plant composition in the Sikka, East Nusa Tenggara is very diverse. The temperature and relative humidity in each altitude area observed was significantly different. One of the endemic species of Flores Island, Eucalyptus urophylla, was only found at 500-700 m asl. There are very limited research on the vegetation diversity held in Flores, East Nusa Tenggara. This research can be the basic for further research in order to explore the potential diversity of flora in this area.

Abstract This study is aimed to discover the diversity of bird species based on the altitude of the area and to discover the impact of vegetation as habitat towards the diversity of bird species in protected forest area in Sirimau Mountain in Soya Village located in Ambon City. The method used to discover the diversity of birds was the IPA-method (Indices Ponctuels d’Abondance) while observing the vegetation used the CSS-method (Continous Strip Sampling) alongside the observation paths. The protected forest consists of three area of different altitudes, namely 300 meters above sea level (masl), 400 masl and 500 masl. The bird species found in the protected forest area in Sirimau Mountain in Soya Village as a whole were 16 species. The forest area at 300 masl was found 14 bird species with diversity index (H’) of 2.57, the forest area at 400 masl was found 12 bird species with diversity index (H’) of 2.42, while the forest area at 500 masl was found 11 bird species with diversity index (H’) of 2.10. There were 8 bird species found in every area of three different altitudes that were dominant such as Perling Ungu (Aplonis motalica), Walet Sapi (Collocalia esculenta), Perkicit Pelangi (Trichoglossus haematodus), Pergam Laut (Ducula bicolor), Sesap Madu Sriganti (Nectarinia jugularis), Srigunting Lencana (Dicrucus bracteatus), Nuri Pipi Merah (Geoffreyus geoffreyi) and Tekukur Biasa (Streptopelia hinensis). Meanwhile, the dominant types of vegetation found in the area were Damar (Agathis sp.), Kayu Merah (Eugenia jambolana) and Meranti (Shorea sp.)

Composition And Structure

We studied the floristic composition and structure of the logged-over peat swamp forest in the  PT National Sago Prima of PT Sampoerna Agro Tbk. group for future management of the conservation area that has been  set aside by the company.  In January - February 2012, 25 quadrats of 20 m x 20 m were laid out systematically along a transect,  thus covering a sampled area of 1-ha.  The results showed that the study site was a regenerating and developing secondary peat swamp forests having high plant species richness.  The total number of species recorded was 73 species of 38 families, consisting of 49 species (30 families) of trees (DBH? 10 cm ), 42 species (24 families) of saplings (H > 1.5 m and DBH < 10 cm), and 41 species (27 families) of seedlings and undergrowth.  Tree density was 550 individuals/ha, and total tree basal area was 18.32 m2. The Shannon-Wiener’s Diversity Index for trees was high  (3.05)  Two tree species with the highest Importance Values (IV) were Pandanus atrocarpus (IV= 45.86 %) and Blumeodendron subrotundifolium (22.46  %).  The tree families with the highest IV were Pandanaceae (45.86), Myrtaceae (40.37), and Dipterocarpaceae (39.20). Forest structure dominated by trees with a diameter below 20 cm amounting to 408 trees/ha (74.05%). and  D and E strata with height of less than 20 m, and density of 431 trees/ha (78.36%). Jaccard Similarity index among species, showed  strong association between Pandanus atrocarpus and Blumeodendron subrotundifolium  and based on this association combined  with high IVs, the two parameters of species  characterized the forest, hence the forest could be designated as the Pandanus atrocarpus--Blumeodendron subrotundifolium association. Primary forest species with high economic values were still present in the forest. Eleven species can be included in the IUCN Red List, of which Shorea rugosa is in the category of Critically Endangered), Shorea tesymanniana Endangered and  Gonystylus bancanus vulnerable, hence they should  be protected.

 ResumoO presente estudo teve por objetivo caracterizar a estrutura de dois trechos de Floresta Ombrófila Densa Aluvial localizados no município de Guaraqueçaba, Paraná. Os aspectos vegetacionais foram relacionados a características ambientais como solos, relevo e profundidade do lençol freático. Para o levantamento fitossociológico foram alocadas 16 parcelas de 10 x 10 m em cada trecho estudado e amostradas todas as árvores com Perímetro à Altura do Peito > 15 cm. Ambas as áreas apresentaram uma associação entre Gleissolo Háplico e Gleissolo Melânico. No total foram identificadas 81 espécies, incluídas em 59 gêneros e 31 famílias. Myrtaceae foi a família de maior riqueza em ambos os compartimentos. O índice de similaridade de Jaccard foi de 29,6%. O índice de diversidade de Shannon (H’) foi maior para o trecho de menor saturação hídrica (H’= 3,13). Para o trecho de maior saturação hídrica H’ foi igual a 2,86 visto que poucas espécies são bem adaptadas aos solos temporariamente ou permanente saturados por água. Em razão da proximidade geográfica e das similaridades climáticas e pedológicas existentes entre os sítios estudados, concluiu-se que as diferenças estruturais e florísticas constatadas estão associadas às condições hídricas do substrato.AbstractPhytosociology analysis of two sites in the Dense Alluvial Ombrophilous Forest with hydromorphic soils, Paraná, Brazil. In the present study, we characterize the structure in two sites of Dense Alluvial Ombrophilous Forest, Guaraqueçaba, State of Paraná, Brazil. Aspects of the vegetation were associated to environmental conditions such as soils, topography and water table depth. For the phytosociological study, 16 plots of 10 x 10 m were established in each site and all trees with Perimeter at breast height > 15 cm were sampled. Both sites presented a mixture of Haplic Gleisoil and Melanic Gleisoil. A total of 81 species were identified, belonging to 59 genera and 31 families. Myrtaceae was the family of greatest richness in both areas. The Jaccard’s similarity index was 29,6%. The Shannon’s diversity index was lower in the site of greater water saturation (H´=2,86). However, few species are well adapted to environmental constraints associated with excess water in the substrate. Due to geographical proximity and similarities of climate and soil between the communities, the main factor determining the structure and floristic composition seems to be closely related to the condition of drainage of the soil.Keywords: Atlantic Forest; coastal plain; caxeta; water saturation.

<p>Anthropogenic impact on the population of ground beetles leads to a change in their numbers, structure of dominance, density, species composition, spectrum of life forms. This makes the beetles Carabidae a convenient and informative bioindicator of the ecological state of biocenoses. The material for this work was the Carabidae collections conducted in June-August 2016-2017 in the park zone of different regions of Barnaul, differing in location, area, hydrological regime, vegetation cover, purpose and anthropogenic load. When processing the material, the quantitative, species and generic composition of the carabidae was determined, calculations were made for such indicators as the Berger-Parker dominance index, the Shannon species diversity index (Hs), and the Jacquard species similarity index. The fauna (Coleoptera, Carabidae) of the park zone of Barnaul is represented by 55 species belonging to 20 genera. The dominant group is represented by species belonging to steppe, forest and polyzonal groups. Forest-steppe species of ground beetles as dominants have not been identified in any of the investigated territories. The greatest variety of ecological groups was noted on the territory of the Yubileyny рark, which is explained by the presence of zones with various microclimatic conditions, the presence of a birch grove that flows through the park with the Pivovarka River, and a wide log in the park. Registered species belong to eight groups of life forms belonging to two classes - zoophagous and myxophytophagous. On the numerical and species abundance, zoophages predominate. The spectrum of life forms corresponds to the zonal spectrum characteristic of the forest-steppe zone.</p><p> </p>

Karst Sinkhole

We reported a study on breeding birds occurring inside an 80 m-deep karst sinkhole, with the characterization of the assemblages recorded along its semi-vertical slopes from the upper edge until the bottom. The internal sides of the sinkhole have been vertically subdivided in four belts about 20 m high. The highest belt (at the upper edge of the cenote) showed the highest values in mean number of bird detections, mean and normalized species richness, and Shannon diversity index. The averaged values of number of detections and species richness significantly differ among belts. Species turnover (Cody’s β-diversity) was maximum between the highest belts. Whittaker plots showed a marked difference among assemblages shaping from broken-stick model to geometric series, and explicited a spatial progressive stress with a disruption in evenness towards the deepest belts. Bird assemblages evidenced a nested subset structure with deeper belts containing successive subsets of the species occurring in the upper belts. We hypothesize that, at least during the daytime in breeding season, the observed non-random distribution of species along the vertical stratification is likely due to (i) the progressive simplification both of the floristic composition and vegetation structure, and (ii) the paucity of sunlight as resources from the upper edge to the inner side of the cenote.
