Bogs are habitats of great environment-modifying value, in particular, play a major role in the formation of the hydrological regime of the surrounding territory. A considerable amount of data has been accumulated on the heterotrophic flagellates associated with wetland ecosystems of the Northern Hemisphere while the large wetlands of the south part of South America remain almost unexplored. Species composition and morphology of heterotrophic flagellates collected from six sphagnum bogs in Chilean part of South Patagonia and Tierra del Fuego in October—November 2015 are described. Fifty-eight species from 33 genera and 3 macrotaxa (Opisthokonta, SAR, Excavata) and heterotrophic flagellates 'incertae sedis' have been recorded. Most of the recorded species are bacterivorous, 7 species — are omnivorous, and 1 — is a predator, feeding on other flagellates. In two bogs of continental part of Chile we have recorded 38 species and forms (38 species in bog no. 1; 1 species in drained bog no. 2), and in four bogs in Tierra del Fuego — we have recorded 39 species and forms (15 species in bog no. 3; 8 species in no. 4; 13 species in no. 5; 16 species in no. 6). Among all aquatic habitats associated with bogs, the greatest number of species has been recorded in hollows (35 species); bogs streams (25); small boggy lakes (24); pool near trunks of Nothofagus and peat excavation with cyanobacterial mat at the bottom (5); only 1 species has been recorded in a drainage canal. All identified flagellates are known from different types offreshwater habitats of the Northern Hemisphere, and most of them (31 species and 10 not identified to species level taxa are known from the bogs of the Northern Hemisphere.

Fecal samples were collected from 120 domestic pigeons to determine the Attributable risk of Ca-pillaria spp. The Capillaria spp. was observed in 64 out of 120 (51%) pigeons (70 males and 50 females) under study. A total of 64 (39 males and 25 females) were naturally infected with Capillaria spp. with 51% and 50% in males and females respectively. Qualitative examinations include the direct microscopy and faecal floatation while quantitative examination includes McMaster technique (worms are calculated per gram of the faeces). Month wise Attributable risk showed that eggs of the worms were found to be abundant in the month of July (60% to 73%) because of high humidity in the month of July during the present study. Very high and very low temperature is not suitable for the proper development of the eggs. Qualitative and quantitative examination revealed that Capillaria spp. was more prevalent in males (51%) than females (50%) but overall there is no significant difference (p>0.05) in the male and female because both of individuals invest equal amount of energy in search of food and incubating the eggs. Different breeds of the pigeons gave different Attributable risk in different months during the whole study. Group of pigeons from different locations showed variable Attributable risk. Areas with high humidity were more suitable for the development of eggs that is the reason that higher Attributable risk was observed in shahdara (75%).
