Radioactive cesium contamination and its biological half-life in larvae of Stenopsyche marmorata (Trichoptera: Stenopsychidae)

The total radioactive Cs concentration in final-instar Stenopsyche marmorata larvae from the Mano River, Fukushima Prefecture, in 2013 was found to be >1000 Bq kg−1 in dry weight. The concentration of radioactive Cs in the river water itself was on the order of 0.01 Bq kg−1, while its concentration in drifting fine particulate organic matter (FPOM) was on the order of 10,000 Bq...

Richness of vascular flora in Lublin city, east Poland, under different urban pressure

Cities are commonly described as mosaics of habitats with increasing degrees of human impact along a gradient from the outskirts to the centers, which may lead to both an increase and a decline in species richness and diversity. Data on species richness in the city of Lublin had been collected in a model transect containing 20 1-km2 study squares. We used ordination methods...

Copper and zinc concentrations of medicinal herbs and soil surrounding ponds on agricultural land

This study measured copper and zinc concentrations in medicinal herbs and soil sampled from three agricultural fields with ponds from mid-June till the end of July 2014. Six herb species were tested: Potentilla anserina L., Mentha arvensis, Achillea millefolium L., Comarum palustre L., Lysimachia vulgaris L., and Lycopus europaeus L. Two of the ponds were in the borough of Jab...

Flow-resistance adaptations of rigid-stemmed aquatic macrophytes in simulated water channels

This study investigated the development of interspecific adaptations of flow-resistance mechanisms to higher flow rates in rigid-stemmed Hygrophila salicifolia (Vahl) Nees (willow leaf Hygrophila sp.) plants placed in simulated water channels. The results indicate that adaptations to higher flow rates include a reduction in: growth rate, average fresh weight, average dry weight...

Regeneration properties of a Populus euphratica riparian forest located in the vicinity of the Ejina Oasis, Inner Mongolia, China

To explore the regeneration properties of a Populus euphratica Oliv. forest under unstable environmental conditions, we performed replicate censuses to determine the sapling dynamics of a P. euphratica population in the vicinity of the Ejina Oasis (Inner Mongolia). Even when the stands were established on riverside flatland, we detected slight variations in ground levels and salt...

The influence of Corvus frugilegus nesting on soil parameters and plant composition in poor and fertile habitats

The functioning of nesting colonies of birds can significantly affect the flora and the soil. Colony species that modify soil characteristics at their nesting sites include the Rook Corvus frugilegus. In order to assess the effect of this species on poor and fertile habitats, we analysed biogenic element concentrations and soil acidity, and investigated the taxonomic...

Importance of closed landfills as green space in urbanized areas: ecological assessment using carabid beetles

In a closed landfill, we investigated the diversity and ecological characters of carabid beetles to understand the ecological importance of closed landfills that have the potential as a multi-functional habitat for improving biodiversity in urbanized areas. In addition, we studied the influence of environmental factors (vegetation structure, soil) on distribution and diversity of...

Structure of the Japanese avian community from city centers to natural habitats exhibits a globally observed pattern

The number of avian species in urban areas throughout the world, particularly in Europe and the USA is low; however, their total density is higher than that observed in surrounding habitats. Nevertheless, it has not been confirmed whether this is true in Japan. Japanese cities have fewer green areas than European and American cities, and Japanese suburbs are likely to face...

The effect of spring water on the growth of a submerged macrophyte Egeria densa

We elucidated the effect of spring water on the growth of Egeria densa Planch., a widespread submerged macrophyte in Japan. We observed the longitudinal distributions of physical (water temperature, particle diameter of the bed sediment, sediment layer thickness, etc.), chemical [pH, dissolved oxygen (DO), dissolved inorganic carbon (DIC), phosphate (PO4-P), total nitrogen (TN...

Hippopotamus and livestock grazing: influences on riparian vegetation and facilitation of other herbivores in the Mara Region of Kenya

Riparian savanna habitats grazed by hippopotamus or livestock experience seasonal ecological stresses through the depletion of herbaceous vegetation, and are often points of contacts and conflicts between herbivores, humans and their livestock. We investigated how hippopotamus and livestock grazing influence vegetation structure and cover and facilitate other wild herbivores in...

Twelve years of vegetation change in an artificial marsh after the transfer of plants and hydrological restoration

For 12 years starting from 1991, we performed vegetation surveys every 2–3 years at permanent plots located in an artificial marsh which was constructed in former rice paddies through sod transplantation from a natural marsh. Management of the artificial marsh was conducted to maintain the condition of the donor vegetation by removing unnecessary plants and ensuring a water...
