Table 1 Papers comparing urban floristic changes over long periods ( > 50 years) of central European and world cities. Full size table In this context, the city of Bologna can be considered a perfect case study for the assessment of long-term floristic changes since two floristic surveys ...
In three cores (GeoB3910, MD09-3246 and MD09-3256Q), located on the Brazilian margin in a region under the influence of the Intertropical Convergence Zone, it is possible to take advantage of the simultaneous recording of rainfall increases during Greenland stadial periods in the marine cores...
An interesting finding is that when we plotted the NaHCO 3 -P and CaCl 2 -P together by a segmented line model, the data showed a uniform trend unrelated to the incubation time. NaHCO 3 -P is seldom used to evaluate P status in sediments in comparison with soils. Yet, our results ...
We studied the variability of physico-chemical parameters in water, and heavy metal contents in water and sediment over time and along the Carpathian Biała Tarnowska River (southern Poland) and related them to catchment geology, human impact and the effect of barriers as a side aspect. The ...
To date, however, no deposits from these eruptions have been identified in cores from the interior of East Antarctica covering this time window, despite tephra from these sources being deposited over the region during earlier time periods (see Narcisi and Petit, 2021). This could be due to ...
Metals would be released into the bottom water, an oxic environment, where scavenging of dissolved metals and resedimentation takes place in relatively short periods of time. Presumably, a long-distance transport of contaminants will not happen. 展开 ...
Studies show that pollutants can be found in the water column, lagoon organisms, or sediments according to their physicochemical properties [25], and water bodies with higher salinity values have shown higher sorption and lower degradation rates of pollutants over time [26]. Regarding chlorophyll-a...
The formation of the aeolian sand environment in the Gonghe Basin is influenced by multiple factors, such as the evolution process of the geomorphology, regional climate, and wind strength, the main control factors were different in different periods [13,14]. The research about the modern ...
During the periods of high obliquity, when the poles are pointing closer to the sun than the equator, water-ice could form in large quantities on the surface at the equator. That ice could then be buried by ash and dust falls, to remain covered to this day. ...
On the other hand, net upstream bottom flow is weak or absent during periods of weak stratification, but it is important when the system is highly stratified [Jay and Smith, 1990]. This can be seen in Figures 5a or 5b, where the ebb-dominant current in the lower layer is dramatically ...
