Abstract The International Mineralogical Association's approved amphibole nomenclature has been revised in order to simplify it, make it more consistent with divisions generally at 50%, define prefixes and modifiers precisely include new species discovered named since 1978, when the previous scheme was approved. same reference axes form basis of most names are little changed but compound like tremolitic hornblende (now magnesiohornblende) abolished also crossite glaucophane or...
A low pressure casting of Mg–Cu–Y melts into copper molds was found to cause amorphous bulks in a cylindrical form. The maximum diameter the cylinder (Dc) shows significant compositional dependence and reaches value 4.0 mm for Mg65Cu25Y10. Dc is similar that temperature span supercooled liquid region, ΔTx(=Tx−Tg). similarity presumably because alloy with large ΔTx has high resistance against nucleation growth crystalline phase resulting from formation disordered structure more dense random...
A complex iridium oxide β-Li(2)IrO(3) crystallizes in a hyperhoneycomb structure, three-dimensional analogue of honeycomb lattice, and is found to be spin-orbital Mott insulator with J(eff)=1/2 moment. Ir ions are connected the three neighboring via Ir-O(2)-Ir bonding planes, which very likely gives rise bond-dependent ferromagnetic interactions between moments, an essential ingredient Kitaev model spin liquid ground state. Dominant interaction moments indeed confirmed by temperature...
SUMMARY Using a newly developed data logger to measure acceleration, we demonstrate that free-ranging king and Adélie penguins only beat their flippers substantially during the first part of descent or when they were presumed be chasing prey at bottom dives. Flipper beating stopped latter ascent: 29±9 % (mean ± S.D.) dive depth(mean depth=136.8±145.1 m, N=425 dives) in penguins,and 52±20 depth depth=72.9±70.5 N=664 penguins. Propulsive swim speeds both species approximately 2 m s-1 dives;...
Satellite telemetry data are a key source of animal distribution information for marine ecosystem management and conservation activities. We used two decades from the East Antarctic sector Southern Ocean. Habitat utilization models spring/summer period were developed six highly abundant, wide‐ranging meso‐ top‐predator species: Adélie Pygoscelis adeliae emperor Aptenodytes forsteri penguins, light‐mantled albatross Phoebetria palpebrata , fur seals Arctocephalus gazella southern elephant...
Measuring the costs of soaring, gliding and flapping flight in raptors is challenging, but essential for understanding their ecology. Among raptors, vultures are scavengers that have evolved highly efficient soaring-gliding techniques to minimize energy find unpredictable food resources. Using electrocardiogram, GPS accelerometer bio-loggers, we report heart rate (HR) captive griffon (Gyps fulvus G. himalayensis) trained freely-flying. HR increased three-fold at take-off (characterized by...

Penguins face a wide range of threats. Most observed population changes have been negative and happened over the last 60 years. Today, populations 11 18 penguin species are decreasing. Here we present review that synthesizes details threats faced by world's penguins. We discuss alterations to their environment at both breeding sites on land sea where they forage. The major drivers change appear be climate, food web marine fisheries. In addition, also consider other critical and/or emerging...
Animal ecology is shaped by energy costs, yet it difficult to measure fine-scale expenditure in the wild. Because metabolism often closely correlated with mechanical work, accelerometers have potential provide detailed information on of wild animals over fine temporal scales. Nonetheless, accelerometry needs be validated animals, especially across different locomotory modes. We merged data collected 20 thick-billed murres ( Uria lomvia ) from miniature measurements daily 24 h using doubly...
The pattern and characteristics of diving two male blue‐eyed shags Phalacrocorax atriceps were studied, using continuous‐recording time‐depth recorders, for a total 15 consecutive days during which the depth, duration, bottom time, ascent descent rates surface intervals 674 dives recorded. Deep (> 35 m, averages80–90 max. 116 m) twice as common (64% versus 34%) shallow (< 21 m 90% < 10 m). long (averages 2.7‐4.1 min, 5.2 min) with half time spent near maximum depth fast travel...
Simultaneous, but contrary, decadal-scale changes in population trajectories of two penguin species the western Pacific and Ross Sea sectors Southern Ocean, during early/mid-1970s again 1988–89, correspond to weather sea ice patterns. These turn are related shifts semi-annual Antarctic oscillations. Populations ecologically dissimilar - Adélie Pygoscelis adeliae emperor Aptenodytes forsteri have been tallied annually since 1950s making these longest biological datasets for Antarctic. Both...
During their long migrations through the Pacific, northern elephant seals, Mirounga angustirostris , never haul out on land and they rarely spend more than a few minutes at time surface. They are almost constantly making repetitive, deep dives, raising question of when do rest? One type dive, drift characterized by time-depth profile with phase lower average descent speed is believed to be resting dive. To examine behaviour seals during we measured body position three-dimensional diving...
