AbstractAlticinae species composition, richness and abundance were investigated and compared between Çığlıkara and Dibek nature reserves in Antalya, at the Mediterranean region of Turkey. The study was conducted in six sites, three for each area (C1–C3 for Çığlıkara, D1–D3 for Dibek). The sites have different vegetation structure and degrees of altitudes: Çığlıkara sites (altitudes 1500–1800 m a.s.l.) are dominated by Cedrus libani; Dibek sites (650–1550 m a.s.l.) by juniper and cedar. Collections, using sweep-net and aspirator, were carried out at 15-day intervals from 2005 to 2006. A total of 4,245 individuals belonging to 60 species of Alticinae were captured. Dibek was distinctly more diverse than Çığlıkara in both years. D1, D3, C3 were the most diverse sites in 2005 while the diversity index values were higher for D1, D2, and D3 in 2006. Cluster analyses using Jaccard and Bray-Curtis indices revealed a high degree of similarity between Alticinae communities at sites D1, C3, and D2 in both years. Comparing Alticinae diversity among sites, the highest species richness and diversity was verified at D1, a forest area including mixed populations of Cedrus, Juniperus and Acer (altitude 1553 m a.s.l.). Factors influencing differences in Alticinae diversity among sites and nature reserves were discussed.

The study of the nesting birds of the coastal riparian zones in Great Kabylia in Algeria, allowed us to identify 45 species of birds, belonging to 12 orders and 26 families. The richest site in terms of species is Takdempt (31 species). The lowest diversity is noted at the level of Boudouaou wadi with 16 species. The values of the Shannon-Weaver diversity index (H') for all sites are quite high (≥3 bits). Concerning the global abundance of avifauna, the site that represents the highest centesimal frequency is that of Takdempt (20.87 %) and this is due to the presence of a colony of Bubulcus ibis (Linnaeus, 1758). The bird communities of the sampled sites are not identical, but the degree of similarity, in general, is quite high (≥ 50 %). The main factors controlling the diversity and the structure of the avifauna of Great Kabylia coastal riparian zones are represented by vertical and horizontal vegetation structure

A study on diversity and abundance of grasshopper and its relatives (Orthoptera) was conducted at two mountainous rainforest ecosystems (Mounts Kendeng and Botol) of Gunung Halimun-Salak National Park. A hundred meters of a line transect was used to sample and set up several insect traps (yellow pan, malaise, pit fall, bait pit fall, sweep net, and light traps), and insect sweepings as well. The light traps were set up at about fifty meters distance from the end of the sampling sites. A total individual collected by traps was combined on every comparable sampling site. Total individuals of the Orthoptera captured were 414; consisted of 25 species of 9 families. Both species diversity and number of families were higher at Mount Kendeng rather than Mount Botol. Number of species of each family usually similar except on family of Grillidae was much higher at Mount Kendeng. Species belong to Phasmidae was not recorded at Mount Kendeng, while species belong to both families of Gryllotalpidae and Tettigonidae were not captured at Mount Botol as well. Overal there was a difference in the species richness at each between. Shannon Diversity Index (H’) and evenness (E) were higher at Mount Kendeng (2.44 and 0.81) rather than Mount Botol (1.80 and 0.66). Similarity Index of Jaccard (Cj) and Sorenson (Cn) of both localities were similar (0.40 and 0.32). Herbivores were most dominant at both localities (Phasmidae, Tetrigidae, Acrididae, Gryllidae, dan Gryllotalpidae), followed by omnivores (Blattidae), scavenger (Gryllacrididae), and predator (Mantidae).

Abstract The primary objective of this study was to investigate the seasonal fish and crustacean variations concerning taxonomic composition, species richness, and diversity in sandy beach habitat. For this purpose, we investigated the Sonmiani Hor lagoon area during four distinct seasons, i.e., northeast (NE) monsoon, pre-monsoon, south-west (SW) monsoon, and post-monsoon for one year. During each haul, the net was pulled about 100m along the beach in 0.5m depth. The results showed a strong linear correlation between the diversity index and equitability in fishes (r = 0.978). The diversity index was strong negatively correlated with the abundance and biomass (r = -0.978, -0.972, respectively). The physical attributes like sea surface water temperature and salinity showed a strong negative effect on species assemblages (r = -0.981 and -0.943, respectively). The mean air and water temperature illustrated approximately 3°C difference during NE and pre-monsoon seasons. However, salinity, pH, and electrical conductivity did not show any significant seasonal variabilities. Under the ecological indices, the fish species displayed higher diversity (H’ = 3.19) during SW monsoon, whereas the lowest diversity was observed during pre-monsoon (H’ = 1.58). The equitability and species richness, however, remained more noticeable during SW monsoon (J’ = 0.81). The total number of individuals of fish and crustaceans reached 4799 with 3813 fish individuals and 986 individuals of crustaceans. A total of 27 families of fish while five crustacean families comprising of 30 genera and 38 fish species while ten genera and 17 species of crustaceans were recorded. Liza subviridis displayed the highest abundance among the sampled fish species. In conclusion, fish species constituted a significant part of the coastal fauna in the study area. The seasonal variations displayed distinct variations in fish species composition and diversity.

Malaise Traps

A study on abundance and diversity of Hymenoptera was conducted in Gunung Datuk, Rembau. Samplings were conducted from November 2014 to February 2015 using six Malaise traps. Three traps were placed at Site 1 at 700m height for high elevation and the remaining traps were placed at Site 2 at 200m height for low elevation. A total number of 221 Hymenopteran were collected which consist of nine families namely Ichneumonidae, Formicidae, Braconidae, Bethylidae, Evaniidae, Tiphiidae, Vespidae, Pompilidae and Apidae. In this study, 93 individuals were obtained from Site 1, comprising nine families and 43 morphospecies while 127 individuals were obtained from Site 2 with nine families and 45 morphospecies. Formicidae was the most dominant family collected from both sites with a total of 104 individuals while the least family recorded was Apidae with only one individual. Shannon’s Weiner Diversity Index (H’) showed Site 1 had the higher diversity value with H’ = 3.17 compared to Site 2 with value H’ = 3.12. For Evenness Index, Site 1 had higher value compared to Site 2 with E’ = 0.84 and E’ = 0.82 respectively. Moreover, for Margalef Richness Index, Site 1 recorded R’ = 9.24 while site two recorded R’ = 9.08 which concluded that Site 1 had higher species richness compared to Site 2. Paired t-test showed that both sites had no significant difference with p>0.05. Overall study showed that the diversity and abundance of Hymenoptera in Gunung Datuk were low since the value of H’ is less than 3.50.

Nematode Diversity

Abstract Background A novel way to study the species composition and diversity of nematode parasites in livestock is to perform deep sequencing on composite samples containing a mixture of different species. Herein we describe for the first time the nematode community structures (nemabiomes) inhabiting Swedish sheep and how these are/were affected by host age and recent anthelmintic treatments. Methods A total of 158 fecal samples were collected (n = 35 in 2007 and n = 123 in 2013–2016) and cultured from groups of sheep on 61 commercial farms in the south-central part of the country where most animals are grazed. Among the samples, 2 × 44 (56%) were paired collections from the same groups pre- and post-treatment with anthelmintics such as macrocyclic lactones, benzimidazoles or levamisole. Samples were analyzed for their nemabiome using the PacBio platform followed by bioinformatic sequence analysis with SCATA. Species richness and diversity were calculated and analyzed in R. Results Nematode ITS2 sequences were found in all larval culture samples except two, even though the fecal egg counts were below the McMaster threshold in 20 samples. Sequencing yielded, on average, 1008 sequences per sample. In total, 16 operational taxonomical units (OTU), all with ≥ 98 % identity to sequences in the NCBI database, were recognized. The OTUs found represented nematode species of which ten are commonly associated with sheep. Multiple species were identified in all pre-anthelmintic treatment larval culture samples. No effects on nematode diversity were found in relation to host age. On the other hand, recent anthelmintic treatment lowered species richness, especially after use of ivermectin and albendazole. Interestingly, despite zero egg counts after use of levamisole, these samples still contained nematode DNA and especially H. contortus. Conclusions Our findings provide evidence that nemabiome analysis combined with diversity index analysis provides an objective methodology in the study of the efficacy of anthelmintic treatment as both high and low abundant species were detected.

Study of morphological characters of Tetranychus macfarlanei Baker & Pritchard and Tetranychus malaysiensis Ehara revealed high similarity by comparing all the important characters in addition to the characters pointed out by Ehara to separate those two species. Molecular phylogeny of seven Indian populations of T. macfarlanei and one population of T. malaysiensis from Philippines along with few distantly related species of Tetranychus was attempted. High degree of similarity between these two species at mitochondrial COI gene (96%) as well as ITS2 (rDNA) (96–99%) region was evident. Based on both morphological features and molecular data, T. malaysiensis is proposed as a junior synonym of T. macfarlanei based on ICZN’s law of priority. Also more female characters are prompted in this study to distinctly discriminate T. macfarlanei from its most resembling species, Tetranychus ludeni Zacher. Tetranychus macfarlanei has emerged as a pest of several cultivated crop plants in India.

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.
