The utilization of marine renewable energies such as offshore wind farming leads to globally expanding human activities in habitats. While knowledge on the responses farms and associated shipping traffic is accumulating now at a fast pace, it becomes important assess population impacts species affected by those activities. In North Sea, protected diver Red-throated Diver ( Gavia stellata ) Blac...

Background: The stabilization of fine sediments via biofilms (‘biostabilization’) has various economic and ecological implications but is presently unaddressed within lotic waters. To investigate natural biofilm growth and functionality in freshwater sediments under controlled boundary conditions, a unique mesocosm was constructed that combines established know-how from engineering and natural ...

This paper presents a series of numerical and field studies to examine the accuracy two field-scale Parshall flumes, which are employed measure flow rate wastewater system in city Minneapolis, Minnesota. The were carried out using large-eddy simulation (LES) level-set methods compute turbulent sewers under two-phase (wastewater air) conditions. Flow measurements conducted dye dilution approach ...

Capsule Recording of behavioural responses to ferry traffic for 11 target species showed that Red-throated Diver Gavia stellata, Slavonian Grebe Podiceps auratus, and Black-throated arctica were most likely react passing vessels.Aim To provide information on how marine vary between waterbird inform spatial planning environmental impact assessments in the near-shore environment.Methods We record...

Rediscovered in the wild twenty years ago, the breeding biology of wild Blue-throated Macaws remains largely unexplored, yet is essential to its effective conservation and recovery. Here, we analyse reproductive parameters in an intensively managed wild population of Blue-throated Macaws, providing the first data on the breeding biology of this critically endangered species. During the six-year...

Numerous studies have correlated the advancement of lay date in birds with warming climate trends, yet the fitness effects associated with this phenological response have been examined in only a small number of species. Most of these species--primarily insectivorous cavity nesters in Europe--exhibit fitness declines associated with increasing asynchrony with prey. Here, we use 25 years of demog...

Although long-distance migratory songbirds are widely believed to be at risk from warming temperature trends, species capable of attempting more than one brood in a breeding season could benefit from extended breeding seasons in warmer springs. To evaluate local and global factors affecting population dynamics of the black-throated blue warbler (Setophaga caerulescens), a double-brooded long-di...
