Abstract Due to the inherently fluid‐mobile nature of W, the 182W record of the early Earth may have been obscured by fluid‐induced mobilization of W. To investigate W mobilization in Archean greenstone sequences, we analyzed 182W isotope systema

Almost fifty years ago the advent of assay methods to measure circulating levels of hormones revolutionized endocrinology in relation to investigations of free-living and captive animals. This new field "environmental endocrinology" revealed that end

In significant contrast to other cratonic blocks of India, the Singhbhum cratonic successions record continuous depositional record from the Palaeoarchaean to Mesoproterozoic. Although the sedimentary facies characteristics and mode of stratigraphic

The Makbal Complex in the northern Tianshan of Kazakhstan and Kyrgyzstan consists of metasedimentary rocks, which host high-P (HP) mafic blocks and ultra-HP Grt-Cld-Tlc schists (UHP as indicated by coesite relicts in garnet). Whole rock major and tra

Captive groups of house sparrows Passer domesticus formed stable social hierarchies during a two-week test period. Higher-ranking individuals were more aggressive during the first week of testing and had higher plasma levels of luteinizing hormone (L

White fronted bee-eaters (Merops bullockoides) live in extended family clans that aggregate to roost and nest in large colonies. Members of a given clan also share a common foraging territory, spatially segregated from the colony, to which they commu

The Antarctic Peninsula has been part of a magmatic arc since at least Jurassic times. The South Shetland Islands archipelago forms part of this arc, but it was separated from the Peninsula following the Pliocene opening of the Bransfield Strait. Dik

By comparison with the general features of metamorphic soles (e.g. vertical and lateral extension, metamorphic grade and diagnostic mineral parageneses, deformation and dominant rock types), it is inferred that the amphibolites, metagabbros and hornb
