Recycling of by-products of the steelmaking process in electric arc (EAF) furnaces is an important activity from the perspective of environmental protection as well as the steelmaking industry itself. This article is a discussion concerning the selected research results in terms of utilisation of steelmaking dusts containing 4 12 % of zinc in manufacture of cement bricks, ceramic construction m...

Habitat fragmentation is the main cause of biodiversity loss, as remnant fragments are exposed to negative influences that include edge effects, prevention of migration, declines in effective population sizes, loss of genetic variability and invasion of exotic species. The Drosophilidae (Diptera), especially species of the genus Drosophila, which are highly sensitive to environmental variation,...

1. Environmental variables are often used as indirect surrogates for mapping biodiversity because species survey data are scant at regional scales, especially in the marine realm. However, environmental variables are measured on arbitrary scales unlikely to have simple, direct relationships with biological patterns. Instead, biodiversity may respond nonlinearly and to interactions between envir...

The monthly total amount of dust fall, as well as its chemical and physical characteristics, was systematically investigated in Shuwaikh city, Kuwait. Dust samples were collected on a monthly basis for the entire year of 2009 and analyzed in the laboratory for water-soluble and water-insoluble matter. Water-insoluble matter represented the major portion of the total annual dust. ANOVAs showed s...

Abstract The lack of knowledge about freshwater biodiversity in remote areas like montane Andean rivers is noticeable and hinder the development efficient conservation plans for aquatic ecosystems. Habitat requirements tropical fishes have been poorly analysed, despite relevance these ecological features on fish strategies. present study aimed to examine assemblages along altitudinal gradient t...

Studies on fish community structure along altitudinal gradients of rivers are lacking in Nepal. This study was carried out to gauge the diversity and composition elevational gradient Ratuwa River. The varies between 70 m 1300 m. Fish samples were collected based habitat representativeness from April (spring) 10-18, July (summer) October (autumn) 2020 January (winter) 2021. A total 3447 specimen...

To describe the seasonal response of major phytoplankton groups to environmental variables along Campeche coast, southeastern Gulf Mexico, seven shallow-water (ca. 1 m) stations were monitored from January 2019 2020. Orthophosphate, ammonium, nitrite, nitrate and silicate measured. Several tests, including ANOVA, Kolmogorov–Smirnov test, Tukey TSD, Bartlett’s test canonical correspondence analy...
