Abundance And Diversity

With the process of urbanization, cities are expanding, while forests are declining. Many conditions in the urban habitats are modified compared to those in the rural ones, so the organisms present reactions to these changes. To determine to what extent the habitat type influences insects, we tested the differences in the pedunculate oak (Quercus robur L.) leaf-mining insect community between urban and rural habitats in Serbia. Lower species richness, abundance, and diversity were determined on trees in the urban environment. Due to the differences in the habitat types, many of the species disappeared, while most of the remaining species declined. The seasonal dynamics of species richness, abundance, and diversity differed between the habitat types. Both rural and urban populations started with low values in May. Subsequently, rural populations gained higher species richness, abundance, and diversity. As about 60% of the leaf miners’ species present in the rural habitats survive on the trees in urban areas, those trees are of great importance as a species reservoir. This is why we need to preserve and strive to improve the condition of urban areas where the pedunculate oak is present.

To identify potential sylvatic, urban and bridge-vectors that can be involved in current or future virus spillover from wild to more urbanised areas, entomological field surveys were conducted in rural, peri-urban and urban areas spanning the rainy and dry seasons in western Cameroon. A total of 2650 mosquitoes belonging to 37 species and eight genera were collected. Mosquito species richness was significantly influenced by the specific combination of the habitat type and the season. The highest species richness was found in the peri-urban area (S = 30, Chao1 = 121 ± 50.63, ACE = 51.97 ± 3.88) during the dry season (S = 28, Chao1 = 64 ± 25.7, ACE = 38.33 ± 3.1). Aedes (Ae.) africanus and Culex (Cx.) moucheti were only found in the rural and peri-urban areas, while Cx. pipiens s.l. and Ae. aegypti were only found in the urban area. Cx. (Culiciomyia) spp., Cx. duttoni and Ae. albopictus were caught in the three habitat types. Importantly, approximately 52% of the mosquito species collected in this study have been implicated in the transmission of diverse arboviruses. This entomological survey provides a catalogue of the different mosquito species that may be involved in the transmission of arboviruses. Further investigations are needed to study the vectorial capacity of each mosquito species in arbovirus transmission.

Abstract:Dung beetles are a functionally important component of most terrestrial ecosystems, but communities change with habitat disturbance and deforestation. In this study, we tested if dung beetle ensembles on dung of introduced cattle and of the endemic anoa, a small buffalo, are affected differentially by habitat disturbance. Therefore, we exposed 10 pitfall traps, five baited with anoa and five baited with cattle dung, per site in six habitat types ranging from natural and selectively logged rain forest to three types of agroforestry system (characterized by different management intensity) and open areas (n = 4 replicate sites per habitat type) at the margin of Lore Lindu National Park, Central Sulawesi, Indonesia. We found 28 species, 43% of which were endemic to Sulawesi. Species richness, abundance and biomass declined from natural forest towards open area. Large-bodied species appeared to be more sensitive to habitat disturbance and the ratio of large to small-sized dung beetles declined with land-use intensity. Although selectively logged forest and cocoa agroforestry systems had lower species richness compared with natural forest, they appeared to maintain a high portion of species originally inhabiting forest sites. The similarity of dung beetle ensembles recorded at forest and agroforestry sites reflects the high similarity of some habitat variables (e.g. vegetation structure and microclimate) between both habitat types compared with open areas. Species richness and abundances as well as species composition, which was characterized by decreases in mean body size, changed with land-use intensity, indicating that dung type is less important than habitat type for determining ensemble structure of these Indonesian dung beetles.

Birds are crucial in maintaining the balance of many ecosystems and provide various ecological services. Understanding their sensitivity to human disturbances should be prioritized in understudy areas for effective conservation practices. Using mist nets, this study characterized mostly understory bird communities (insectivorous, frugivorous, granivorous, and nectarivorous birds) in three habitat types (pristine forest, selectively logged forest, and young oil palm plantation) in the Talangaye rainforest, Southwest Cameroon. A total of 845 birds belonging to 27 families and 85 species were recorded in the three habitats after 294 h of mist netting. Overall, the mist-netted community was largely dominated by insectivores, followed by frugivores, nectarivores, granivores, and carnivores. Although mean species richness, abundance, and Simpson diversity index did not vary significantly among habitat types, mean species abundance and diversity index decreased in selectively logged forest and young oil palm plantation and species richness increased in both habitats. The species richness, abundance, and diversity index for insectivorous and frugivorous birds were lowest in the young oil palm plantations. For granivores, species richness and abundance increased following selective logging and the establishment of oil palm plantation. The highest mean species richness and diversity index in nectarivores were recorded in the young oil palm plantations. The study showed that selective logging and establishment of oil palm plantation had variable effects on the bird communities in the Talangaye rainforest. Also, the frugivorous birds appeared to be more sensitive to both types of disturbances, while the insectivores were more sensitive to habitat loss/conversion.

AbstractSurveying and monitoring bat populations by recording their calls with stationary detectors has become increasingly popular. This study tested the hypothesis that placing stationary detectors at water bodies yielded more species than in other habitat types in a temperate landscape (settlement, forest, open land). The number of species was significantly affected by habitat type, and sampling at water bodies yielded approximately 50% more species than in open land, the habitat type which was second in species richness. In contrast, bat calling activity was not significantly related to habitat type. With the exception of the northern bat

The counts of breeding Jackdaws were made in Kharkiv City, Ukraine in April – early June of 2016–2017. We estimated the breeding density among different habitat types. For such a purpose the city area was divided into 0.25 km² squares (n = 1354) and we estimated the numbers of pairs within the boundaries of 40 squares (QGIS program was used to choose randomly these squares). The surveys were made in April–May (19 squares) and early June (4 squares) in 2016 and April–May (10 squares) and early June (7 squares) in 2017. The surveys were made within main habitat types such as area of residential blocks of flats, residential area (1–2-storey buildings), industrial area, forest zone, park zone and undeveloped urban areas. The data on the area occupied by every major habitat type (in km²) were calculated by QGIS program. The 90 % of the territory of Kharkiv City was analysed, except water reservoirs and traffic way areas. The data of the surveys were extrapolated across areas of the same habitat types. Also we have searched for Jackdaw colonies within the boundaries of Kharkiv City to take these data into account. According to the collected data the Jackdaw prefers to nest in crevices of old 3–5-level buildings at built-up districts or in round cross-sections of posts at blocks-of-flats areas. Thus the mean density here was 22 pairs/km². The mean density of Jackdaw in industrial areas was 15 pairs/km², in undeveloped urban areas – 1.2 pairs/km², and in residential area (1–2-storey buildings) – 0.7 pairs/km². The total number of breeding Jackdaws in Kharkiv City was estimated at 2325 to 2630 pairs. The mean density of Jackdaws was 7.5 pairs/km². Taking into account the moderate decline in the population of the Jackdaws in some European countries (although in general the population trend remains stable within the continent), and the lack of the surveys of the breeding distribution and numbers of Jackdaws in large cities of the Eastern Ukraine, it’s reasonable to use our data as an optimal starting point for the monitoring of the regional population trend of the species. The data of 2016 year survey were used in European Breeding Bird Atlas 2 (EBBA2) programme (square 37UCR2).

Abstract Urbanisation is a leading cause of biodiversity loss and habitat fragmentation internationally, and the conservation of representative native assemblages is a challenge confronting environmental managers in expanding urban landscapes. This study investigates the bird assemblages occurring in a rapidly growing regional centre, Ballarat, southeastern Australia. It aims to examine the relationships between urbanisation and bird communities in a regional city by investigating the differences in bird assemblage composition related to the type of vegetation (native or exotic) in urban streetscapes. Bird surveys were completed across four broad habitat types: remnant vegetation, exotic streetscapes, native streetscapes and newly developed streetscapes. Each habitat type had three 1 ha replicate sites. Results show that remnant vegetation fringing residential areas and native streetscapes supported around 60% more native bird species than exotic and newly developed streetscapes. Avian species composition was significantly different between broad habitat types, with remnant vegetation and native streetscapes maintaining representative native bird assemblages, but exotic streetscapes and newly developed streetscapes were dominated by introduced birds. Our results show that, for representative native bird assemblages to be maintained in urban areas, the maintenance of remnant and native vegetation is essential.

ABSTRACTCommunity structure, macrohabitat selection, and patterns of species co-occurrence were examined during a 14-month study of small mammals in the Cerrado Province of central Brazil. Data were collected from mark-recapture grids in brejo and gallery forest, and from live-trapping and specimen collection in all habitat types within cerrado (campo limpo, campo sujo, cerrado [s.s.], cerradão, brejo, valley-side wet campo, and gallery forest). Gallery forest supported the highest species richness, most complex vertical distribution of species, highest level of trophic diversity, and highest macroniche diversity. Degree of habitat selection varied widely. All habitat types supported both rodents and marsupials, although marsupials tended to be much less common in the grasslands (campos) than in woodlands (cerrado) and forests (cerradão, gallery forest). Some species, such as Didelphis albiventris, occurred in all habitat types, while others were much more restricted. Oryzomys bicolor, for example, ocur-red only in gallery forest. No habitat type had a completely distinct fauna: overlap in species composition always occurred with at least one other habitat type. Because of the great variability of habitats, and the fact that subsets of the mammal fauna were frequently habitat specific, the overall species richness of any portion of mixed cerrado vegetation is remarkably high.
