Infestation of interior walls buildings with fungal mould is a reason for health concern which exacerbated in energy-efficient that limit air circulation. Both mycological and mycotoxicological studies are needed to determine the potential hazards residents. In this paper, rare case occurrence Stachybotrys chartarum an apartment building Lubuskie Province Poland has been described. Isolated as ...
Black flies have medical importance because some species are vectors of the unenocerciasis and Mansonelosis, nevertheless, their ecology and potential use as bioindicators is still poorly studied in the Neotropical Region. In Brazil, bioindicators use is strongly focused in a multimetrical ecological index approach; this way, we investigated the black fly spatial distribution, in relation to ab...
Overgrazing, via harvesting of forage species and decrease the other herbs, is of progressive factors in biodiversity destroying. In order to investigate the animal grazing impacts on changing of plant structure and diversity, we selected the comparison between this effect with exclosure area, and proving of the excluded area effects on plant diversity; two sites of Kojour rangeland, Mazandran ...
Background and purpose: Bioindicators are microorganisms directly associated with environmental changes which their numbers are affected by chemical pollutants. Materials and methods: Sampling was done from four stations in Shirood River in depth of 20 cm of water surface and transferred to laboratory in less than 24 hr. KF medium, SPS, ECC Chrome agar, Plate count agar were used for isolati...
(1) Background: Monitoring programs are essential to conservation but often restricted by limited financial resources. Optimal monitoring can lead higher cost-effectiveness. (2) Methods: In this study, we used butterflies as bioindicators assess the effects of filling a dam in Brazilian Amazon. We studied flooding on butterfly assemblages through samples collected before and after flooding. con...
Sentigi (Pemphis acidula) is one of the mangrove species that classified as pure stand so it has potential to be used an indicator in area Gili Sulat. The research location ganti dengan Kawasan Konservasi Laut Daerah (KKLD) Sulat Lombok Timur. purpose this study was determine characteristics sentigi environmental bioindicators forests Sulat, East Lombok. method done by delineation using high re...
The objective of this work was to investigate the patterns of diversity and abundance of ciliates protozoa community in three tropical urban streams and verify which species can be considered bioindicators of water quality. In each stream, three regions (headwater, middle and mouth) were sampled in two years, in the rainy and dry seasons. The abiotic factors (dissolved oxygen, pH, temperature, ...
Monitoring the bioaccumulation of chemical elements within various organismal tissues has become a useful tool to survey current or chronic levels of heavy metal exposure within an environment. In this study, we compared the bioaccumulations of As, Cd, Cu, Fe, Pb, Se, and Zn between the American alligator, Alligator mississippiensis, and its parasites in order to establish their use as bioindic...
According to the Convention on Biological Diversity (CBD) the development of bioindicators is extremely necessary to achieve the conservation targets by 2010, and insects are considered an effective group for this goal. Drosophilids are regarded as potential indicators, although this idea remains untested. Therefore, we followed up a protocol to test the drosophilid potential indicator for huma...
