Confined turbidite sand-sheets in the Paraná and Paganzo Basins
(Universidade do Vale do Rio dos Sinos, 2014-02-20)
During the Late Paleozoic, Gondwana was home for a protracted glaciation that generated high sediment supplies and ample accommodation space within incised valleys and fjords, usually laterally confined and longitudinally ...
Demographic history inferred from genome-wide data reveals two lineages of sheldgeese endemic to a glacial refugium in the southern Atlantic
(Wiley Blackwell Publishing, Inc, 2016-04)
Aim The Malvinas/Falkland Islands (MFI) constitute the largest archipelago inthe southern Atlantic, and harbour endemic lineages that presumably evolvedafter sea-level rise, associated with glacial periods, isolated ancestral ...

Investigating South American biogeographic history using patterns of skull shape variation on Cerdocyon thous (Mammalia: Canidae)
(WILEY-BLACKWELL, 2009)
Patterns of geographic variation of the canid Cerdocyon thous have historically been obscured by its remarkable intraspecific morphological variability. The observed distribution is highly associated with phytophysiognomy, ...

Deglacial climate and relative sea level changes forced the shift from eolian sandsheets to dunefields in southern Brazilian coast
(Elsevier B.V., 2020-09-15)
Quaternary sea level and climate changes can promote spatio-temporal shifts in themorphology of coastal eolian depositional systems. A shift of depositional features such as from sandsheets to dunefields occurs as response ...
Golgi method without osmium tetroxide for the study of the central nervous system
(1992)
A variant Golgi technique was developed that consisted of substituting osmium tetroxide with formaldehyde as the initial fixative in intracardiac perfusion, along with the addition of glacial acetic acid to the chromating ...
