Benthic macroinvertebrates were sampled seasonally in the subtidal and upper and lower swash zones at two sites in each of six nearshore habitat types on the lower west coast of Australia. The habitat types, which differed mainly in the extent of their exposure to wave activity and whether sea grass and/or nearshore reefs were present, had been distinguished quantitatively using values for a suite of seven statistically-selected enduring environmental characteristics (Valesini et al., 2003). The core samples yielded 121 species representing eight phyla, among which the Polychaeta, Malacostraca and Bivalvia were the most speciose classes, contributing ∼38, 23 and 10%, respectively, to the total number of individuals. The total number of species and mean density of macroinvertebrates at the most protected habitat type (1), i.e. 70 and 209·2 individuals 0·1 m−2, respectively, were far greater than in any other habitat type. Habitat type influenced species composition to a greater extent than either zone or season. Furthermore, the extents of the differences among the species compositions of the six habitat types statistically matched the extents of the differences among the values for the suite of enduring environmental characteristics that distinguished each of those habitat types. Overall, the species composition at habitat type 1 was the most distinct, containing five abundant species of polychaetes that were adapted to deposit-feeding in calm waters with high levels of organic material and which were rare in all other habitat types. In contrast, the fauna at the most exposed habitat type was characterized by four crustacean species and a species of bivalve and polychaete, whose mobility and tough external surface facilitated their survival and feeding in turbulent waters. The zonal differences in faunal compositions among habitat types were greatest in the case of the subtidal zone. The faunal compositions differed among zones and seasons only at the most protected habitat type.

The ecology of phlebotomine sandflies in an endemic focus of cutaneous leishmaniasis in Northern Venezuela (San Esteban, Carabobo State) was investigated through a year-term study. Three different habitats: viz. a house, a pridomestic area and a sylvatic area, were covered and the species composition, the abundance and occurrence of each species were analyzed in relation to the habitats, catching methods and hour of catching. L. panamensis, L. gomezi and L. ovallesi are the species which bite man, although almost exclusively at night. All of them hide by day and are common in the sylvatic area. Moreover, L. panamensis and L. gomezi successfully approach the house and seem to settle in the peridomestic area. L. shannoni and L. olmeca bicolor also approach and accidentally bite man. L. trinidadensis, L. atroclavata and L. cayennensis are the common non-antrhopophilic species in the area.

Species Composition And Structure

Tugun Coregonus tugun (Pallas, 1814) is an endemic of Siberia. Information about the species composition and structure of tugun parasite community on the stage of spawning migration is described in this paper. We carried out ichtioparasitologic studies in the Yenisey and the Khatanga Rivers in 2011-2014. Tugun parasite complex from the Khatanga River remains statistically identical in species composition, number of individuals and biomass and differs from those of the Yeniseis tugun over the entire study period. Apparently two different stocks of tugun were investigated in the Yenisei River. One of them lives in the Yeniseis streambed, the other one lives in the Podkamennaya Tunguska River. The composition of the parasitic fauna of tugun from two rivers is formed by generalist species. Tugun parasites component communities from all material collection stations have high values of the Shannon index and two dominant species (by numbers of parasites and by biomass). We found out that the species biomasses differ significantly on the graphic community structure. The description of tugun parasite communities corresponds to characteristic of a climax community on the stage of destruction except the graphic structure. In the analyzed parasitic communities the processes of egg laying and larval appearance, the death of parasites of previous year generation and infection with this year parasites occur simultaneously. The stages of formation and destruction of the community overlap. The described state of tugun parasites communities has an adaptive value. The load on the host body is reduced which ensures the long-term existence of parasites.

Objective of research. To study the species composition of the parasite fauna and the infestation rate of the spiny loach Cobitis taenia Linnaeus, 1758 from Saratov Reservoir. Materials and methods. The material was collected in the Mordovo-Kol’tsovsky area of the Reservoir (the middle part of the reservoir) in 2009 and 2014–2015. Fishing was carried out by a hydrobiological net. Totally 47 individuals of spiny loach were investigated by the method of full parasitological autopsy. Collection, fixation and office studies were carried out using the standard technique; diagnostics of species composition of parasites — by identification guides. To estimate the rate of fish invasion, we used the common parasitological indices: extensity of invasion, intensity of invasion and the index of abundance of parasites. Results and discussion. 7 species of parasites belonging to 5 classes: Monogenea — 1, Cestoda — 1, Trematoda — 3, Nematoda — 1, Bivalvia — 1 were found in the spiny loach Cobitis taenia Linnaeus from Saratov Reservoir. The species composition of parasites and the level of host infestation directly depend on the lifestyle and nutrition of fishes. Eating the infected benthic and weed bed invertebrates (oligochaetes, larvae and adult insects), the spiny loach becomes infected with 3 species of helminths. 4 species of parasites infect the host using the active infestation way. Most of the parasites found in fish from different families and groups are wide specific. The parasite fauna includes 1 species, narrow specific for the spiny loach (monogenea Gyrodactylus latus Bychowsky, 1933) and 1 species specific for loaches (fam. Cobitidae) — metacercariae of Holostephanus cobitis Opravilova, 1968. For 4 species of parasites, the spiny loach is the final (definitive) host, for 3 — intermediate. The dominant species in the composition of the parasite fauna C. taenia is the trematode H. cobitidis (mtc.); the extensity of infection with it reaches 97,9%, the abundance index is 10,8 ind. Fluke larvae infect fishes (using the active way) penetrating through the skin. The most pathogenic for spiny loach parasites are the monogenea G. latus, metacercariae of trematodes H. cobitidis and Paracoenogonimus ovatus Katsurada, 1914, the larva of the nematode Raphidascaris acus Bloch, 1779.

The species diversity of the insects of Nimphalinae subfamily (Lepidoptera order), which are stored in the entomological collection of The Botany and Zoology Department of Ternopil Volodymyr Hnatiuk National Pedagogical University were studied. The insects were collected by the students during their teacher training and also by the amateur entomologists during 2000–2020. These insects are in the collections of The Botany and Zoology Department. The species composition of the collected insects was analyzed. There are 202 individuals of Nimphalinae subfamily. Identified insects belong to five genus (Vanessa, Inachis, Agаlis, Polygonia, Nymphalis). The largest number of individuals of this subfamily was calculated (Inachis io –75, Vanessa atalanta – 52, Cynthia cardui – 45). Also 13 individuals of Agаlis urticae and 12 individuals of Polygonia c-album were found. All species of Rhopalocera of European fauna are in The International Union for Conservation of Nature (IUCN) Red List of Threatened Species. Most of them are classified as Least Concern (LC). Widespread, numerous and common species of the Nimphalinae subfamily were found in the funds of The Botany and Zoology Department. Identified species belong to the LC category of The IUCN Red List. The Compton tortoiseshell (Nymphalis vaualbum) is included in The Red Data Book of Ukraine (2009). Its conservation status is invaluable. Nymphalis vaualbum was not found in the entomological collections of The Botany and Zoology Department of TNPU.

The Amazon region is one of the most diverse areas in the world. Research on high tropical forest diversity brings up relevant contributions to understand the mechanisms that result and support such diversity. In the present study we describe the species composition and diversity of 15 one-ha plots in the Amazonian terra firme dense forest in Brazil, and compare the floristic similarity of these plots with other nine one-ha plots. The 15 plots studied were randomly selected from permanent plots at the Embrapa Experimental site, Amazonas State in 2005. The diversity was analysed by using species richness and Shannon’s index, and by applying the Sorensen’s index for similarity and unweighted pair-group average (UPGMA) as clustering method. Mantel test was performed to study whether the differences in species composition between sites could be explained by the geographic distance between them. Overall, we identified 8 771 individuals, 264 species and 51 plant families. Most of the species were concentrated in few families and few had large number of individuals. Families presenting the highest species richness were Fabaceae (Faboideae: 22spp., Mimosoideae: 22spp.), Sapotaceae: 22spp., Lecythidaceae: 15 and Lauraceae: 13. Burseraceae had the largest number of individuals with 11.8% of the total. The ten most abundant species were: Protium hebetatum (1 037 individuals), Eschweilera coriacea (471), Licania oblongifolia (310), Pouteria minima (293), Ocotea cernua (258), Scleronema micranthum (197), Eschweilera collina (176), Licania apelata (172), Naucleopsis caloneura (170) and Psidium araca (152), which represented 36.5% of all individuals. Approximately 49% of species had up to ten individuals and 13% appeared only once in all sampled plots, showing a large occurrence of rare species. Our study area is on a forest presenting a high tree species diversity with Shannon’s diversity index of 4.49. The dendrogram showed two groups of plots with low similarity between them (less than 0.25), and the closer the plots were one to another, more similar in species composition (Mantel R=0.3627, p<0.01). The 15 plots in our study area share more than 50% of their species composition and represent the group of plots that have the shortest distance between each other. Overall, our results highlight the high local and regional heterogeneity of environments in terra firme forests, and the high occurrence of rare species, which should be considered in management and conservation programs in the Amazon rainforest, in order to maintain its structure on the long run.

An ecological and physiological study of Common Eider (Somateria mollissima) nesting on the coast of Eastern Murman was carried out. The species composition of helminthofauna of birds and the quantitative parameters of the infection were studied. It is established that trematodes of the genus Microphallus, three species of cestodes - Lateriporus teres (Cestoda: Dilepididae), Fimbriarioides intermedia (Cestoda: Hymenolepididae), Microsomacanthus diorchis (Cestoda: Hymenolepididae) and one species of acanthocephalan - Polymorphus phippsi (Palaeacanthocephala: Polymorphidae) parasitized in the small intestine of Common Eider. It is shown that the activity of proteases decreased at the locations of F. intermedia and M. diorchis in the intestines of birds, with infestation with the acanthocephalan P. phippsi, on the contrary, increased. The activity of glycosides in the intestinal mucosa was reduced in comparison with the control values by infection cestodes M. diorchis. There was an increase in the values of hematological indices in infected individuals relative to the control parameters.
