Comparison of oxygen isotope records from the GISP 2 and GRIP Greenland ice cores
(2,670 m at GRIP), it is not possible to determine the duration of anomalous features thinner than 20 m. In both cores, some of the features near the marine isotope stage 5e/ 6 boundary4.H that are…
Tracing the sources and spatial distribution of organic carbon in subsoils using a multi-biomarker approach
Soil organic carbon (SOC) from aboveground and belowground sources has rarely been differentiated although it may drive SOC turnover and stabilization due to a presumed differing source dependent…
Organic matter composition and stabilization in a polygonal tundra soil of the Lena Delta
This study investigated soil organic matter (OM) composition of differently stabilized soil OM fractions in the active layer of a polygonal tundra soil in the Lena Delta, Russia, by applying density…
Organic geochemical and palynological evidence for Holocene natural and anthropogenic environmental change at Lake Dojran (Macedonia/Greece)
In this study, we present lipid biomarker and palynological data for a sediment core from Lake Dojran (Macedonia/Greece), which covers the entire Holocene period. We analyzed vascular plant-derived…

Histological changes in the oocytes of the estuarine crab, Scylla serrata (Forskal) after eyestalk ablation
TLDR
Histological sections of the ovary show that the animals having immature ovary reach the maturing stage and those with mature ovary become ripe or occasionally even spawn in the laboratory within a short time following eyestalk ablation.
