Changes in Wind Pattern Alter Albatross Distribution and Life-History Traits
Westerly winds in the Southern Ocean have increased in intensity and moved poleward. Using long-term demographic and foraging records, we show that foraging range in wandering albatrosses has shifted poleward in conjunction with these changes in wind pattern, while their rates of travel and flight speeds have increased. Consequently, the duration of foraging trips has decreased, breeding success has improved, and birds have increased in mass by more than 1 kilogram. These positive consequences of climate change may be temporary if patterns of wind in the southern westerlies follow predicted climate change scenarios. This study stresses the importance of foraging performance as the key link between environmental changes and population processes.

Space dogs : the story of the celebrated canine cosmonauts
\"This fascinating book tells the story of the soviet space dogs, illustrated with legendary photographer Martin Parr's vintage space-dog memorabilia. In the 1950s the space race between the USA and the USSR was well and truly on, and was for both a matter of pride and propaganda. But before man ventured into the cosmos, his four-legged friends would pave the way for space exploration. The first canine cosmonaut was Laika, meaning 'barker'. The little stray could never have anticipated that she would one day float 200 miles above the Moscow streets. She would be canonized as a proletarian hero, appearing on stamps, postcards and souvenirs. Her successors were Belka and Strelka, the first dogs to successfully return safely to Earth, and with them, the cult of the space dog was born. In a regime that eschewed celebrating individual achievement, the space dogs became Soviet superstars, with a vast array of merchandise, books and films in their honor. A must for read for fans of Soviet Space Dogs by Olesya Turkina and Designed in the USSR: 1950-1989 by Moscow Design Museum.\"-- Amazon.com.

Primitive Early Eocene bat from Wyoming and the evolution of flight and echolocation
Bats (Chiroptera) represent one of the largest and most diverse radiations of mammals, accounting for one-fifth of extant species. Although recent studies unambiguously support bat monophyly and consensus is rapidly emerging about evolutionary relationships among extant lineages, the fossil record of bats extends over 50 million years, and early evolution of the group remains poorly understood. Here we describe a new bat from the Early Eocene Green River Formation of Wyoming, USA, with features that are more primitive than seen in any previously known bat. The evolutionary pathways that led to flapping flight and echolocation in bats have been in dispute, and until now fossils have been of limited use in documenting transitions involved in this marked change in lifestyle. Phylogenetically informed comparisons of the new taxon with other bats and non-flying mammals reveal that critical morphological and functional changes evolved incrementally. Forelimb anatomy indicates that the new bat was capable of powered flight like other Eocene bats, but ear morphology suggests that it lacked their echolocation abilities, supporting a 'flight first' hypothesis for chiropteran evolution. The shape of the wings suggests that an undulating gliding-fluttering flight style may be primitive for bats, and the presence of a long calcar indicates that a broad tail membrane evolved early in Chiroptera, probably functioning as an additional airfoil rather than as a prey-capture device. Limb proportions and retention of claws on all digits indicate that the new bat may have been an agile climber that employed quadrupedal locomotion and under-branch hanging behaviour.

A Mesozoic gliding mammal from northeastern China
Gliding flight has independently evolved many times in vertebrates. Direct evidence of gliding is rare in fossil records and is unknown in mammals from the Mesozoic era. Here we report a new Mesozoic mammal from Inner Mongolia, China, that represents a previously unknown group characterized by a highly specialized insectivorous dentition and a sizable patagium (flying membrane) for gliding flight. The patagium is covered with dense hair and supported by an elongated tail and limbs; the latter also bear many features adapted for arboreal life. This discovery extends the earliest record of gliding flight for mammals to at least 70 million years earlier in geological history, and demonstrates that early mammals were diverse in their locomotor strategies and lifestyles; they had experimented with an aerial habit at about the same time as, if not earlier than, when birds endeavoured to exploit the sky.
