Dendrocopos Syriacus

Abstract Non-forest tree stands are important habitats for many species of birds in the agricultural landscape. They are also the main habitat of the Syrian Woodpecker Dendrocopos syriacus, whose numbers have been decreasing in recent years in some parts of Europe. Recognition of the habitat requirements of this species may help better planning of its protection in the context of the treed agricultural landscapes. During this study, the habitat preferences of the Syrian Woodpecker were determined in the agricultural landscape of South-Eastern Poland. A set of 12 habitat parameters of tree stands located in the breeding territories of the Syrian Woodpecker (n = 122) and in randomly chosen control areas (n = 122) located outside the range of the breeding territories of this species were characterized. The number and species diversity of trees was significantly higher in stands located in Syrian Woodpecker territories than in the random control areas. Stands occupied by breeding pairs also had trees of worse health condition and a larger proportion of fruit trees. The model best explaining the probability of the occurrence of the species indicates that the Syrian Woodpecker requires mainly the presence of tree stands with a greater species diversity of trees, as well as tree stands in worse health condition. When planning the protection of this species’ habitats in the agricultural landscape, the characteristics of non-forest tree stands noted above should be taken into account.

I conducted a survey of aculeate Hymenoptera in urban and suburban gardens of Brno-city in August 2015. For my survey, I selected three individual gardens, and in each of them chose three type of microhabitats: tree, grass and patch. I used yellow pan traps for taxon sampling. Using this method, I recorded 382 specimens belonging to 76 species. Subsequently, the basic indices of species diversity in individual gardens were calculated, and statistical analyses of individual gardens and various microhabitats were created. I report large differences between the Aculeata taxa found in urban and suburban gardens. Habitat preferences of species between microhabitats were discovered as well. Furthermore, I report 14 species mentioned in the Red List of threatened species of the Czech Republic (Straka 2005a,b) (hereinafter referred to as Red List); as well as one invasive species Isodontia mexicana (Saussure, 1867) and one species Pison atrum Spinola, 1808 recently reported as new for the Czech Republic (reported after the publication of the Red List itself).

Conservation for both biodiversity and ecosystem services are an important issue worldwide. However, knowledge of their relationship remains limited. As habitat structure is strongly related to regional biodiversity, we studied cultural ecosystem services by using habitat structure as a proxy for biodiversity. Specifically, we used human preference, assessed by using photos with location information (i.e. geo-tagged digital pictures) as an index of a cultural ecosystem service. We conducted nature walks in semi-natural environments for cognitively-impaired students from a local special school and studied the photos they took during the walks. We analysed the habitat preferences inferred from the photo locations and the composition of the photos—whether they were close-up, scenic or landscape views. The results showed that levels of human preference and biodiversity, indicated by habitat structure, had a positive relationship. During spring to autumn, when levels of biological activity are higher, people tended to show more preference in close-up views (i.e. the subject of the photo was the species itself). In winter, they tended to be interested in scenic views that were not strongly influenced by species diversity. Additionally, photos taken in areas with threatened species almost always included close-up views, although not of the threatened species themselves. Areas with high species diversity therefore appeared to be more appealing to the participants. These results suggest that habitat diversity could not only contribute to biodiversity, but also provide cultural ecosystem services. Habitat conservation for semi-natural environments could be synergised for both biodiversity conservation and general human well-being.

Amphibian Species

Study on amphibian species diversity and habitat preferences was conducted in six protected areas of Bangladesh between March 2011 and July 2012. A total of 32 species of amphibians were recorded under six families. Family Dicroglossidae comprised the highest number of species (12) where Bufonidae the lowest (1 species). Among these species 34% were uncommon, 31% common, 19% rare and 16% very common. Alpha diversity was the highest in Dudpukuria- Dhopachari Wildlife Sanctuary (28) and the lowest in Sitakunda Eco-park (13). Beta diversity was the highest (11) between Inani Protected Forest and Sitakunda Eco-park and the lowest (3) between Dudpukuria-Dhopachari Wildlife Sanctuary and Teknaf Wildlife Sanctuary. Jaccard index of similarity among the amphibian communities was the highest (J=0.90) between Dudpukuria-Dhopachari Wildlife Sanctuary and Teknaf Wildlife Sanctuary and the lowest (J=0.54) between Inani Protected Forest and Sitakunda Eco-park. Fifty percent of the species were found to use more than two habitats, while only 16% species were restricted to a single habitat. Significant number of the species (20 species) were found to use forest edges, aquatic environment (19 species), forest floor (15 species), agricultural land (13 species), bushes (7 species) and tree habitats (3 species).Bangladesh J.

The Impact

AbstractNatural habitat degradation often involves the reduction or disappearance of bee species. In Africa, stingless bees are hunted for honey, which is used as food, for medicinal purposes, and for traditional rituals. Severe habitat degradation due to human settlement is hypothesized to have a negative impact on the species diversity of the African stingless bee species. In this paper, we assess the impact of habitat degradation on the diversity of five stingless bee species across different habitats in the tropical rainforest of Kenya (indigenous forest, mixed indigenous forest) and its neighbouring landscape (grassland, village) in western Kenya. The species fauna, nest occurrence, and species diversity of the stingless bee species varied across the different habitats. The number of nesting habitats of the meliponine species varied between habitats in the tropical rainforest.Meliponula ferruginea(reddish brown) nested in five habitats, whileMeliponula bocandeiandMeliponula ferruginea(black) nested only in two habitat types. The species richness decreased within the different types of habitats and the indigenous and mixed indigenous forest contained more species than other habitats. The fauna composition in both homesteads was exclusively similar, while the indigenous and mixed indigenous forests were mostly similar. Similarity in habitat preferences for nesting was revealed betweenM. bocandeivsPlebeina hildebrandtiandM. ferruginea(reddish brown) vsHypotrigona gribodoi. The natural native indigenous forest had the most diverse community compared to the degraded habitats. There are taxon-specific responses to habitat change; and in our study, there is clear value in conserving the native indigenous forest.

SUMMARYThis study provides the first comprehensive information on the parasite fauna of the white-streaked grouperEpinephelus ongus. A total of 35 specimens from the archipelago Karimunjawa, Java Sea, Indonesia were studied for metazoan parasites. For comparison, the documented parasite community of 521E. areolatus,E. coioidesandE. fuscoguttatusfrom previous studies were analysed. A total of 17 different parasite taxa were recognized forE. ongus, including 14 new host and four new locality records. This increases the known parasite taxa ofE. ongusby more than 80%. The ectoparasite fauna was predominated by the monogeneanPseudorhabdosynochus quadratusresulting in a low Shannon index of species diversity of the entire parasite community (0.17). By contrast, the species diversity excluding the ectoparasites reached the highest value recorded for Indonesian epinephelids (1.93). The endoparasite fauna was predominated by generalists, which are already known from Indonesia. This demonstrates the potential risk of parasite transmission throughE. ongusinto mariculture and vice versa. One-way analyses of similarity revealed a significantly different parasite community pattern ofE. onguscompared withE. areolatusandE. fuscoguttatusas well as minor differences withE. coioides. This finding refers to different habitat preferences of these epinephelids within the analysed size range.

Various habitats found on Langkawi Island such as agricultural fields, peat swamps, lowland forests, upland forests, and riverine forests are occupied by many species of anuran fauna. These variations provide a platform to explore species diversity, distribution, and other ecological parameters to understand the distribution patterns and to facilitate the management of important species within particular areas. The objective of this study was to compare species richness of anuran species in different types of habitat on Langkawi Island, Malaysia. We surveyed seven types of habitat, namely agriculture (AG), coastal (CL), forest (FT), pond (PD), fisherman village near estuarine mangrove (FVM), riparian forest (RF), and river (RV). A total of 775 individuals were recorded, representing 23 species from 14 genus and six families known to occur on Langkawi Island. Forest (FT) and riparian forest (RF) (both forest habitats) indicated relatively high values of Shannon Index (H’), 2.60 and 2.38 respectively, compared to the other non-forest habitats, CL (1.82), RV (1.71), FVM (1.56), PD (1.54), and AG (1.53). Rank abundance curves showed that the majority of disturbed habitats displayed geometric series models and broken stick models, whereas forest habitat types (FT and RF) represented log normal models. The performance of species richness estimators varied but Chao 1 estimator performed well for many sampled habitat types and showed the tendency to coalesce with Sobs (Mao Tau) curves except for CL and FVM. As expected, the forested habitat (FT and RF) was more diverse in species diversity compared to those of non-forest groups. Nevertheless, non-forested species were found in abundance, highlighting the relevance of these habitats in supporting the amphibian fauna. This study highlights the importance of habitat types in structuring species diversity and community structures and suggest that the information may be useful to improve conservation practices of inland amphibian habitats.

AbstractBarrier-pitfall traps and tree bands were used to sample adult carabid beetles in five forest stands of different tree species composition and spruce budworm infestation levels. Twenty genera and 37 species were collected over the 2-year period. Adult carabid populations were highest in the red spruce stand while carabid species diversity was greater in hardwood and fir stands having the most tree species diversity. Potential adult carabid predators of spruce budworm were identified using 5 criteria: number of individuals, habitat preferences, seasonal abundance, size, and food. We conclude that adults of Pterostichus pensylvanicus (Lec.) had the highest potential as predators of spruce budworm followed by Platynus decentis Say, Calosoma frigidum Kby., Pterostichus tristis (Dej.), Cymindis cribricollis Dej., Pterostichus rostratus (Newm.), Calathus ingratus Dej., and Pterostichus adoxus (Say).
