Contourite erosional and depositional features of the Maastrichtian chalk on Jasmund peninsula (Rügen island, NE Germany)

Sedimentology, EarlyView.
ABSTRACT Seismic‐scale features such as deeply incised submarine valleys and mounded drifts together with ichnological features indicative of discontinuous sedimentation and erosional episodes have recently been documented from the Upper Cretaceous chalk in the southern Baltic Sea area.

Drowned carbonate‐rimmed margin controlling shelf‐edge delta progradation and sedimentation dynamics: Upper Cretaceous Woodbine Formation, Texas, USA

Sedimentology, EarlyView.
ABSTRACT Shelf‐edge deltas are commonly interpreted to record basinward facies migration across uninterrupted, gently dipping shelf margins; however, examples from mixed siliciclastic‐carbonate margins reveal more complex depositional dynamics. Periods and areas of carbonate sedimentation within mixed siliciclastic‐carbonate margins can modify shelf ...

Animal Segregation: The Biopolitics of Concentrated Pig Farming

Tijdschrift voor Economische en Sociale Geografie, EarlyView.
Abstract This paper explores the possibility to think through the concept of animal segregation to understand the more‐than‐human geographies of livestock animals. By redirecting the analytical tools for studying the spatial separation of humans to the segregation of animals, this paper contributes to understanding the geographical processes of ...

AABB survey on directed blood donation practices

Transfusion, EarlyView.
Abstract Background Standardized guidance regarding the processes for collecting directed blood donations (DBD) is lacking, leading to variable practices. This study assessed laboratory, clinical, and charging practices for DBD collection in the United States and Canada. Study Design and Methods An electronic survey was distributed to United States and

Through the Sands of Time: Evolutionary History and Systematics of the Awl‐Headed Snakes (Colubridae: Lytorhynchus) in the Saharo‐Sindian Region

Zoologica Scripta, EarlyView.
ABSTRACT The psammophilous colubrid genus Lytorhynchus is widely distributed in the deserts of the Saharo‐Sindian region and adjacent areas. The taxonomy of the genus and the number of recognised species have remained unstable since the last taxonomic revision in 1970, with differing views on the taxonomic status of L. gaddi and L. kennedyi.

Neotropical Snakes Reveal Different Geological Times for Dispersal Corridors Between Amazon and Atlantic Forests

Zoologica Scripta, EarlyView.
ABSTRACT Three forested dispersal corridors have been proposed within the diagonal of open/dry landscapes in South America and the relative importance of each one has been the subject of debate for forest organisms. We analysed the biogeographical history of three snake genera (Bothrops, Philodryas, and Micrurus) from different families (Viperidae ...

Systematic and Taxonomic Revision of Ostrea stentina Species Complex (Bivalvia: Ostreidae): New Insights From a Topotype‐Based Integrative Approach

Zoologica Scripta, EarlyView.
ABSTRACT Cryptic marine species complexes with plastic morphology, shallow divergence, and broad distributions are among the hardest taxonomic problems in zoology. The Ostrea stentina complex, reported across the Atlantic, Mediterranean, and Indo‐Pacific, is a striking example. We present the first topotype‐anchored integrative revision of this complex,
