Habitat alteration impacts predation risk in an aposematic amphibian
Clay models of fire salamanders in the Vienna Woods suffer more predation attempts in managed forest zones than in protected ones. These differences are mainly due to increased predation by birds in managed areas, which are characterised by higher tree species diversity.

Temperature effects on compensatory responses in an early spring‐breeding amphibian
To better understand how phenological shifts may affect organisms with complex life histories as well as effects across life stages, we experimentally evaluated larval wood frog (Rana sylvatica) responses to hatching phenology and increased pond temperatures.

An investigation into the controls of granite plutonism in the Sierra da Freita region, Northern Portugal [PDF]
The Serra da Freita region of north central Portugal was chosen for study as it displays the complex relationships between regional structure, plutonism, regional and contact metamorphism typical of this part of Iberia.

Origin and significance of 'dispersed facies' basal ice: Svínafellsjökull, Iceland [PDF]
Dispersed facies basal ice - massive (i.e. structureless) ice with dispersed debris aggregates - is present at the margins of many glaciers and, as a product of internal glacial processes, has the potential to provide important information about the ...

Field Studies of the Archean in Grand Canyon [PDF]
The oldest rocks of Arizona which form the precipitous walls of the inner or granite gorge of the Grand Canyon have never received the intensive study that has been given to their counterparts over the great northeastern plains of Canada, in the ...

Abstract Xenoliths in carbonaceous chondrites include lithologies that are unrepresented in the meteorite record and so are a rich source of information on asteroid diversity. Cold Bokkeveld is a CM2 regolith breccia that contains both hydrous and anhydrous lithic clasts. Here, we describe a hydrous clast with a fine‐grained rim.

Abstract JAXA's Hayabusa2 sample return mission visited the volatile‐rich carbonaceous (C‐type) asteroid (162173) Ryugu with the aim of ground‐truthing remote observations, returning a pristine sample from a C‐type asteroid, and strengthening links between asteroids and the meteorite collection. Here, we have conducted a systematic study of coarse (>10

Reflection of sequence of geodynamic processes in geological structure of the Bug area
The age of formations composing granulite blocks of the Ukrainian Shield is a pro-blem for disputes. In order to ascertain the primary genesis and conditions of transduction of the Bug area rocks it is proposed to find out how was deep process realized ...

Thermal structure and exhumation history of the Lesser Himalaya in central Nepal [PDF]
The Lesser Himalaya (LH) consists of metasedimentary rocks that have been scrapped off from the underthrusting Indian crust and accreted to the mountain range over the last ~20 Myr. It now forms a significant fraction of the Himalayan collisional orogen.
