Injuries in deep time: interpreting competitive behaviours in extinct reptiles via palaeopathology

open access: yesBiological Reviews, EarlyView.
ABSTRACT For over a century, palaeopathology has been used as a tool for understanding evolution, disease in past communities and populations, and to interpret behaviour of extinct taxa. Physical traumas in particular have frequently been the justification for interpretations about aggressive and even competitive behaviours in extinct taxa.

Watersheds assessment of Kurdistan Province From the perspective of active tectonics with a quantitative- comparative approach based on analysis of drainage network [PDF]

open access: yesنشریه جغرافیا و برنامه‌ریزی, 2018
The study, according to the importance of tectonic – geomorphology studies, deals with the assessment and classification of active tectonic of watershed in Kurdistan province with a comparative – quantitative approach based on the parameters of drainage ...

Geological processes shaping freshwater biodiversity: a synthesis of global evidence

open access: yesBiological Reviews, EarlyView.
ABSTRACT Recent genomic data highlight the key roles of geological processes in shaping the diversification and biogeography of freshwater lineages. Specifically, physical processes such as tectonic uplift, erosion, glaciation, lake formation, and sea‐level fluctuation contribute extensively to the evolution of biotic diversity within and among ...

Impact of global seismicity on sea level change assessment

open access: yes, 2005
We analyze the effect of seismic activity on sealevel variations, by computing the time-dependent vertical crustal movement and geoid change due to coseismic deformations and postseismic relaxation effects.

The 1980, 1997 and 1998 Azores earthquakes and its seismotectonic implications [PDF]

open access: yes, 2007
We have studied the focal mechanisms of the 1980, 1997 and 1998 earthquakes in the Azores region from body-wave inversion of digital GDSN (Global Digital Seismograph Network) and broadband data. For the 1980 and 1998 shocks, we have obtained strike– slip

Assessment of active tectonic by using geomorphic indices in Dezful- Andimeshk basin

open access: yesتحقيقات جغرافيايی, 2020
Aims and Backgrounds: Almost no area in the world can be found that has not been affected by tectonic processes. The morpho-tectonic indices of the basin are used to investigate the active tectonics.

Morphoneotectonics of the Abruzzo Periadriatic Area (Central Italy): Morphometric Analysis and Morphological Evidence of Tectonics Features

open access: yesGeosciences, 2021
Drainage basin-scale morphometric analysis and morphological evidence of tectonics represent helpful tools to evaluate and investigate morphoneotectonic processes in tectonically active regions.

Neogene plate tectonic reconstructions and geodynamics of North Island sedimentary basins: Implications for the petroleum systems [PDF]

open access: yes, 2006
Although the modern Australia-Pacific plate boundary through New Zealand is relatively straight, there have been significant changes in its geometry during the Neogene. Within the North Island sector there has been a fundamental transition from an Alpine

Optimal mud pressure design using nonlinear failure criteria for wellbores in shaley sedimentary reservoir

open access: yesDeep Underground Science and Engineering, EarlyView.
The present study uses the Modified Mohr‐Coulomb true‐triaxial failure criterion (MMC_TT), which predicts the strength of rock better than the MGC criterion in laboratory true‐triaxial tests to overcome the limitations. Moreover, based on the data from previously published five vertical wells in the Krishna‐Godavari basin (K‐G basin), an empirical ...

The first ultra-high resolution Digital Terrain Model of the shallow-water sector around Lipari Island (Aeolian Islands, Italy) [PDF]

open access: yes, 2015
Very high resolution bathymetric map obtained through multibeam echosounders data are crucial to generate accurate Digital Terrain Models from which the morphological setting of active volcanic areas can be analyzed in detail. Here we show and discuss
