Internal Structure, Kinematics, and Prehistory of Frozen Debris Lobe‐A (FDL‐A), Brooks Range, Alaska
Permafrost and Periglacial Processes, EarlyView.ABSTRACT Frozen Debris Lobe‐A (FDL‐A)—one of hundreds of FDLs in the Brooks Range of northern Alaska—is a slow‐moving landslide in permafrost that has been the subject of research since 2008 due to its close proximity to the Dalton Highway. Here, we synthesize more than a decade's worth of climate and surface measurements of monitored FDLs, and the ...

Acta Palaeontologica PolonicaIn the fields of functional morphology, paleoecology, and taxonomy, the Bryozoan Skeletal Index (BSI) is an increasingly useful metric for the degree of calcification in bryozoan colonies. The goal of this study is to quantify how it varies from proximal

The role of conodonts in the global stratigraphic correlation on example of southern Siberia (Russia) and eastern Serbia [PDF]
Geološki Anali Balkanskoga Poluostrva, 2015 Conodonts are very precise tools for global stratigraphic correlation of Devonian deposits. They can be correlated at the level of standard conodont zones even for basins having very different geological structure.

Appraisal of Six Natural Mica Reference Materials for In Situ Rb‐Sr Geochronology
Geostandards and Geoanalytical Research, EarlyView.Key Points Evaluated six natural mica reference materials for in situ LA‐ICP‐MS/MS Rb‐Sr geochronology using geochemical, microstructural and isotopic characterisation. Identified robust primary reference materials: Mount Dromedary biotite (99.37 Ma) and Mica‐Fe biotite (307.75 Ma). La Posta biotite and Högsbo muscovite are suitable secondary reference

Insect Molecular Biology, EarlyView.Parasitoid wasps deploy maternal and embryonic factors to reprogramme host physiology. Venom, calyx fluid, polydnaviruses, teratocytes and larval secretions act in a coordinated, compartmentalised manner. Host‐regulation factors are promising sources of insecticidal, antimicrobial and bioinspired translational molecules.

Middle Devonian and Frasnian bryozoan fauna from the Holy Cross Mountains, Poland
Acta Palaeontologica PolonicaThe present paper describes a bryozoan fauna from the Devonian of Holy Cross Mountains (Poland) which includes nine species. Six species were described from the Dobruchna Member of the Skały Formation (Eifelian) of Skały section: Cyclotrypa sp ...
