SummaryFieldwork on the distribution, habitat preferences and status of birds was conducted in the Bikin River basin, northern Ussuriland, south-east Russia, during May–July 1992,1993,1995,1996 and 1997. The results of this survey combined with data collected during 1960–1990, show the area to be of high conservation priority and one of the most important for the conservation of Blakiston's Fish Owl Ketupa blakistoni, Chinese Merganser Mergus squamatus, Mandarin Duck Aix galericulata and Hooded Crane Grus monacha. This paper reports on all of the 13 threatened and near-threatened breeding species of northern Ussuriland, with special emphasis on their occurrence and status in the Bikin area. Three more species, included in the Red Data Book of Russia, are also briefly discussed. Maps show the distribution of the breeding sites of the species discussed. The establishment of a nature reserve in the lower Bikin area is suggested as the only way to conserve the virgin Manchurian-type habitats (wetlands and forests), and all 10 species of special conservation concern. Monitoring of the local populations of Blakiston's Fish Owl, Chinese Merganser and Mandarin Duck in the middle Bikin is required.

The study assessed factors that influenced bird-habitat preference, diversity, and spatial distribution in Mole National Park. Birds were identified using point count sampling method, while ordination techniques were performed to determine the influence of environmental factors on bird-habitat preference. A total of 4951 individuals belonging to 131 species were identified across the four habitat types in the wet (n= 3033) and dry (n= 1648) seasons. Despite the high abundance and richness of birds in the woodland and shrubland habitats, grassland habitat was the most diverse, due to the high spatial evenness distribution of the birds. Bushfire, patchiness, and animal trampling were the key environmental determinants in bird assemblages and habitat preferences and accounted for 62.02% and 81.82% variations in the two seasons. Rarer birds like White-Backed Vulture (NT) and White-Headed Vulture (CR), Bateleur Eagle (NT), and Woolly-Necked Stork (VU), with high conservation concern, suggest intensification of conservation effort, while the dominance of Sahel Bush-sparrow was probably due to their broad range habitat preferences and ability to adapt to environmental conditions across these habitats. These species could be used as indicators of habitat quality, if future scenarios restrict their movement or distribution in narrow range habitats.

Macroinvertebrate Density

During one year we studied caddisfly assemblages in benthic macroinvertebrate communities of mountain (Frikena River) and piedmont (Partizanka River) reaches of the Lyutoga River Basin. For most of the year in the mountain reaches, the scraper Neophylax ussuriensis Martynov dominates. Maximum caddisfly density (403 ind./m2) and biomass (14,441 g/m2) was recorded in July before mass emergence of that dominant species. The density of caddisflies in the benthic community was more significant in November (32%), and caddisfly biomass was most significant in July (69%). In the piedmont reaches of Lyutoga River Basin in various seasons, Rhyacophila (Hyporhyacophila) sp., Hydatophylax sp., Hydropsyche orientalis Martynov, and Stenopsyche marmorata Navás dominated. Maximum density and biomass of caddisflies (451 ind./m2, 1,576 g/m2) were recorded in 5 September. The density of filterers H. orientalis and S. marmorata occurs in the salmon spawning season and seems to be correlated with the increased abundance of suspended organic substances in the water column as salmon spawn. In the piedmont reaches the role of caddisflies are the most significant in September (49% of total macroinvertebrate density and 56% of biomass).

We provide a checklist of 45 species of amphibians from Lai Chau Province, northwestern Vietnam. Thirteen of species are recorded for the first time from Lai Chau Province; these include four species of Dicroglossidae, four species of Megophryidae, three species of Ranidae, and two species of Rhacophoridae. We also provide descriptions of the newly recorded species. The amphibian fauna of Lai Chau Province is of high conservation concern, with three species endemic to Vietnam, 10 species listed in the IUCN Red List, and two species listed in the Red Data Book of Vietnam.

North-central part of the Svydovets Mts with adjacent upper Chorna Tisa river basin belongs to the most preserved and less disturbed mountain ecosystems in the Ukrainian Carpathians characterized by high biotic and landscape diversity. This area has been highly threatened lately because of the construction of a large recreation ski and spa resort “Svydovets” is being planned here. An unprecedentedly massive disturbance and transformation of natural complexes in the area about 15-20.000 ha is expected to happen on the territory, which is almost unpopulated and hardly accessible. This area is characterized by unique low-disturbed high-mountain glacial landscapes, valuable hydrological objects, old-grown and virgin forests of high conservation value, habitats and populations of dozens of threatened plant and animal species. At least 43 rare and threatened species of vascular plants, 14 – invertebrates, 4 – amphibians, 19 – birds, 14 – mammals included in the Red Data Book of Ukraine (2009) occur here. The high-mountain zone of the Svydovets Mts is exceptionally significant for biodiversity conservation in the Ukrainian Carpathians as one of the most important refuges of the relic boreal-alpine and endemic Carpathian biota. Implementation of the mentioned ambitious business project will lead to destructive consequences for natural ecosystems and landscapes of the whole Svydovets mountain range as well as deterioration of hydrological regime and contamination of the upper Chorna Tisa river basin. It will pose the threat of devastation to ecosystems of the unique glacial mountain lakes, mires and rocks, riverine and subalpine forests, habitats and populations of many rare plants and animals protected in Ukraine and in the European Union. In these circumstances, the need emerges to establish the “Central Svydovets Mts” Nature Protected Area of national importance which could protect the natural environment and biodiversity within the territory threatened by the unacceptable business project.

Socio Economic Factors

We investigated the role of socio-economic factors in the proliferation of mosquito vectors in two adjacent but socio-economically contrasting neighborhoods in Baton Rouge, LA, USA. We surveyed mosquito larvae habitat, mosquito larvae, and adult mosquitoes during the summer of 2020. We also evaluated the number of requests for mosquito abatement services in the years preceding the study for each area. While we did not find differences in terms of the most abundant species, Culex quinquefasicatus (F1,30 = 0.329, p = 0.57), we did find a higher abundance of mosquito habitats, particularly discarded tires, as well as larvae (z = 13.83, p < 0.001) and adults (F1,30 = 4.207, p = 0.049) of the species Aedes albopictus in the low-income neighborhood. In contrast, mosquito abatement requests were significantly higher in the high socio-economic neighborhood (z = −8.561, p < 0.001). This study shows how factors such as adjudicated properties, discarded tires and pest abatement requests can influence the abundance of mosquito vectors, disproportionately affecting low-income groups. This study also highlights how Aedes spp. may be better indicators than Culex spp. of socio-economic differences between nearby neighborhoods, due to their short flight range and habitat preferences, and this should be considered in future studies attempting to detect such disparities in the future.
