Spatial-temporal patterns of ecological-environmental attributes within different geological-topographical zones: a case from Hailun District, Heilongjiang Province, China

open access: yesFrontiers in Environmental Science
The climate change and extension of human activities are shedding more stresses on ecosystems. Ecological zoning could help manage the ecosystem and deal with environmental problems more effectively.

The physics of wind-blown sand and dust [PDF]

open access: yes, 2012
The transport of sand and dust by wind is a potent erosional force, creates sand dunes and ripples, and loads the atmosphere with suspended dust aerosols.

Reevaluation of Wolfcampian Cyclothems in Northeastern Kansas: Significance of Subaerial Exposure and Flooding Surfaces [PDF]

open access: yes, 1993
Ten cyclothems from the Wolfcampian of northeastern Kansas, including parts of the Council Grove and Chase Groups, were examined in detail with particular attention to discontinuity surfaces and paleosol development.

Stratigraphy and development of the Late Miocene-Early Pleistocene Hawke’s Bay forearc basin [PDF]

open access: yes, 2004
A Late Miocene-Early Pleistocene mixed carbonate-siliciclastic sedimentary succession about 2 500 m thick in the Hawke’s Bay forearc basin is the focus of a basin analysis. The area under investigation covers 3 500 km2 of western and central Hawke’s Bay.

Chronic Wasting Disease management responses in North America: A public policy analysis

open access: yesWildlife Society Bulletin, EarlyView.
In this study we use the Multiple Streams Framework from public policy theory to assess the responses of wildlife management agencies in states and provinces with CWD‐positive cases in the United States and Canada to alleviate public concerns and manage the spread of this disease.

Structural and magnetic investigations of the Weyl semimetal family CeAlSi1–xGex

open access: yesActa Crystallographica Section B, EarlyView.
A systematic investigation is reported of the structural and magnetic evolution in the CeAlSi1–xGex series, combining X‐ray and neutron diffraction with magnetization measurements on polycrystalline samples and single crystals. Chemical substitution leads to a continuous lattice expansion and a suppression of the ferromagnetic ordering temperature ...

Morphometric and Paleobiological Insights Into Pleistocene Sicilian Wolf Populations

open access: yesActa Zoologica, EarlyView.
ABSTRACT The Pleistocene wolves (Canis lupus) from Sicily represent one of the few known insular populations of this species from that time period. Despite their potential relevance for understanding carnivore adaptations in insular contexts, no dedicated study has previously investigated their morphology and evolutionary significance.
