La investigación ha permitido describir la diversidad faunística (herpetofauna) en cacaotales y rastrojos, Siuna- 2011, en 15 unidades productivas, distribuidas en 5 comunidades. Se caracterizaron plantaciones de cacao y rastrojos para determinar la diversidad de herpetofauna, mediante un estudio cuantitativo-observacional-comparativo. Los resultados muestran: las tipologías de cacao multiestratos con 5 representaciones, cacao simple con 8 y cacao con musáceas 2. En rastrojos de 1 a 5 años 11 representaciones, de 6 a 10 años 1 representación y de 11 a 15 años 3. Las especies de reptiles encontradas fueron: 197 individuos agrupados en 24 especies y 10 familias y 17 géneros en todas las tipologías de cacao. En rastrojos menores a 5 años se encontraron 12 especies y 30 individuos que representan el 51.72%. En cacao y rastrojos no hay diferencias entre hábitat para las especies de herpetofauna, debido a que las parcelas muestreadas se encontraban una contiguo a la otra. El índice de diversidad dio valores de mediana diversidad (2,368 – 2,236) en ambos sitios de alta diversidad tanto en cacaotales y rastrojos superiores a 0.66 para Simpson 1-D.SummaryThe research has described the faunal diversity (herpetofauna) in cacao plantations and stubble, in the municipality of Siuna, year 2011, in 15 productive units distributed in 5 communities. Cacao and stubble plantations were characterized in order to determine the diversity of herpetofauna, through a quantitative-observational-comparative study.The results showed different typologies: multilayer cacao: 5 representations; simple cacao: 8, and cacao with musaceas: 2. Related to stubble from 1-5 years there are 11 representations; from 6 to 10 years 1 representation and 11-15 years 3 representations. The reptile species found were: 197 individuals grouped into 24 species and 10 families, as well as 17 types of cacao.In stubbles under 5 years, 12 species and 30 individuals were found representing 51.72%. In cacao and stubbles there is no difference between habitats for herpetofauna species, due to the fact that the sampled plots were contiguous one with the other. The diversity index gave median values diversity (2.368 to 2.236) in both sites of high diversity, both in the cacao and stubbles above 0.66 for 1-D Simpson.

The diversity and species composition of the water beetles in peat bog lakes, streams and hollows in Belarus were studied. In total, 45 species of water beetles belonging to 3 families (Gyrinidae, Dytiscidae, Hydrophilidae) were sampled by entomological net. Hydroporus tristis, Ilybius aenescens, Enochrus affinis, and E. ochropterus are the most abundant species A rather high diversity was recorded (Shannon-Wienner diversity index H′ = 2.037–2.912). Shannon-Wienner indexes indicated higher values in the lakes, whereas the lowest values in the hollows were recorded. In addition, in hollows water beetle species composition was the most different from the other peat bog water bodies.

Studies on carton nesting ants and domatia−dwelling ants have shown that ant–fungi interactions may be much more common and widespread than previously thought. Until now, studies focused predominantly on parasitic and mutualistic fungi–ant interactions occurring mostly in the tropics, neglecting less−obvious interactions involving the fungi common in ants’ surroundings in temperate climates. In our study, we characterized the mycobiota of the surroundings of Formica polyctena ants by identifying nearly 600 fungal colonies that were isolated externally from the bodies of F. polyctena workers. The ants were collected from mounds found in northern and central Poland. Isolated fungi were assigned to 20 genera via molecular identification (ITS rDNA barcoding). Among these, Penicillium strains were the most frequent, belonging to eight different taxonomic sections. Other common and widespread members of Eurotiales, such as Aspergillus spp., were isolated very rarely. In our study, we managed to characterize the genera of fungi commonly present on F. polyctena workers. Our results suggest that Penicillium, Trichoderma, Mucor, Schwanniomyces and Entomortierella are commonly present in F. polyctena surroundings. Additionally, the high diversity and high frequency of Penicillium colonies isolated from ants in this study suggest that representatives of this genus may be adapted to survive in ant nests environment better than the other fungal groups, or that they are preferentially sustained by the insects in nests.

This research was conducted in March 2019 to determine the oil content in sediment, it’s community structure of macrozoobenthos and it’s a relationship in Belawan Waters of Medan City, North Sumatera. Four sampling stations with five replications in each station were surveyed. The results showed that the average oil content in sediments exceeded the threshold had set by the National Academy of Science. Macrozoobenthos found consists of Ocypode quadrata, Scyla serrate, Rotun dicauda, Penaeus sp, Murex tribulus, and Nassarius olivaccus. The highest abundance was in Station 3 and the lowest was in Station 2. The diversity index in each station was generally very low. Dominance Index in Station 4 was medium, whilst the other stations were high. Evenness index showed in Station 3 and 4 were in high population, Station 1 was in medium population and Station 2 was in low population. Simple linear regression analyses between oil content in sediment with community structure of macrozoobenthos indicated negative correlation ( Y = 10,5-0,0001x , R2 = 0,0004 and r = 0,02 ) which indicated that the higher the oil content, the lower the macrozoobenthos abundance in sediment.

A comprehensive inventory of faunal biodiversity was conducted within three Key Biodiversity Areas of Central Visayas. Mt. Bandilaan Natural Park (MBNP), Balinsasayao Twin Lakes Natural Park (BTLNP), and Rajah Sikatuna Protected Landscape (RSPL). Three primary wildlife groups were surveyed: bats, birds and amphibians. Species diversity and population trends were then analyzed to assess areas of biodiversity importance. RSPL generally had the highest species richness and diversity index while MBNP consistently had the lowest. When pooled. The surveyed areas resulted in a high diversity index and rate of endemicity showing the importance of multiple areas of protection. These findings can be utilized to prioritize habitat protection as well as to serve as a baseline information for future biodiversity inventories. J. Biodivers. Conserv. Bioresour.

Abstract Thirty-six species of terrestrial molluscs were found in the dry grasslands and rock outcrops of the study area, including three that were not previously known for Central Ukraine: Granaria frumentum, Pupilla bigranata and Mediterranea inopinata. These species are relics related to dry open habitats and require conservation in Ukraine on the national level, G. frumentum is already listed in the Red Book of Ukraine, and the other two should be listed in its next edition. It is proposed to create the new protected areas in the most important newly revealed locations of these species. These rocky areas also retain the high diversity of land molluscs in the region. The invasive snail Xeropicta derbentina was found for the first time on the DNIPRO Upland, on the edge of natural dry grassland. The rare native snail Morlina glabra was recorded for the first time in Kyiv Region, it is proposed to be included into the regional red list.

Description of five new Dolichopoda species from the Ionian area of Western Greece together with a description of the female for D. pavesii from Kefalonia island and the male of D. dalensi from North-eastern Peloponnisos are reported. Considering the other 6 species already documented in the area (including the North of the Peloponnisos), there is now a total of 11 recorded species of Dolichopoda which currently inhabit the underground areas of this zone. These new data, therefore, help better define the already high diversity of the genus in the Hellenic region (25 species in all) reinforcing the hypothesis that there was a central area of dispersion of the Dolichopoda in the ancient Aegean plate.

The red-eared slider Trachemys scripta elegans is currently the only reptile species that can be legally sold as a pet in Singapore. We report on the species of tortoises and freshwater turtles that were found for sale during a survey of 27 pet shops in 2004. Although the red-eared slider was the most common species for sale, small numbers of 11 other species were available. Of these, the import of one species (the Chinese soft-shell turtle Pelodiscus sinensis) is allowed for food but import of the other 10 species is not permitted for either food or the pet trade. We found that illegally held chelonians are often not kept on the pet shop premises. Our findings suggest that the Singaporean authorities' efforts to address illegal wildlife trade have to include other methods in addition to conducting raids on shop premises.

Soundscape design in city parks is important for a better visiting experience. The aim of this research is to find a more effective way to design soundscapes in city parks, by exploring the relationships between certain physical and psychoacoustic parameters and soundscape composition parameters as proposed in this study, including perceived loudness of individual sound (PLS), perceived occurrences of individual sound (POS), and soundscape diversity index(SDI). The parameters were based on soundscape information gathered with a specifically designed soundwalk method in five city parks in Xiamen, China. The results showed that the soundscape composition parameters play important roles as soundscape parameters. LCeq–LAeq, LA10–LA90 and sharpness showed more explanatory power to the soundscape composition parameters of individual sound categories than other physical and psychoacoustic parameters. PLS of human sounds was the most frequently introduced variable for nearly all the other objective parameters, followed by SDI. Some of the soundscape composition parameters were found to be mutually explainable, including PLS of human sounds with LA10, LCeq–LAeq and sharpness, respectively, POS of traffic sounds with LA10, and PLS of both mechanical and geophysical sounds with sharpness, which supply important information for soundscape design in city parks.
