Habitat and spatial trends of U.K. wintering waterbird populations over 50 years
Abstract The United Kingdom is an important wintering ground for millions of waterbirds. Most U.K. wintering waterbird populations increased between 1970 and the mid‐1990s, but declined thereafter. We examined U.K. population indices in 46 wintering waterbird species in two 25‐year periods, 1970–1994 and 1995–2019, to identify which waterbird groups ...

The Zooplankton of Lake Chany, West Siberia, Russia
ABSTRACT In August of 2002, we surveyed the zooplankton community of an inland saline lake in West Siberia, Russia—Lake Chany. Thirty species were found, including cladocerans, copepods, and rotifers. The dominant cladocerans were Daphnia longispina, Daphnia magna, Ceriodaphnia reticulata, and Chydorus sphaericus; the dominant copepods were the ...

Time‐stressed Bar‐tailed Godwits exploit novel prey during migratory fuelling
Long‐distance migratory birds breeding in the Arctic face challenges as earlier snowmelt shifts the timing of vital resources. To keep up with these advancements, birds will need to modify their migration. Higher fuelling rates during stopover have been identified as a critical mechanism for accelerating migration, but this requires adequate food ...

FIRE EXTINGUISHING IN FLOWING WELLS IN WEST SIBERIA
The article describes some technical means for fire killing in flowing wells of West Siberia. Some recommendations are offered on firefighting depending on a strength and configuration of the uncontrolled gas blowout. It is proposed to perform the gas blowout killing by separation of the flame from the well head without its extinguishing with placement

Geolocation reveals wintering sites of near‐extinct Caucasian breeding sea duck
We obtained 14 sets of full annual cycle geolocator tracks from 13 individual nesting female Velvet Scoter Melanitta fusca from the relict Caucasian population at their last remaining breeding site, Lake Tabatskuri, Georgia. Results showed that females wintered at widespread discrete localities in Ukraine, around the coasts of the Crimean Peninsula and
