The species composition of rotifers in three hydroelectric reservoirs of western highlands, central Vietnam

In particular, the highest similarity was found between reservoirs in western highlands and Phu Ninh lake, Quang Nam Province while the largest difference in species composition was observed between western highlands and Bau Thiem lake, Thua Thien Hue Province.

Assessment of the zooplankton community structure of the coastal Uzungöl Lagoon (Kızılırmak Delta, Turkey) based on community indices and physicochemical parameters

The objective of this study is to provide information on the zooplankton community and physicochemical properties of Uzungöl Lagoon. Sampling studies were performed at monthly intervals for abiotic factors and community parameters between September 2015 and August 2016. The variations of zooplankton community were estimated using Shannon-Weiner diversity (H’), Pielou evenness (J), species richness (S), frequency, and dominancy indices. The relationship between environmental variables and community parameters were analyzed with Pearson’s correlation test and redundancy analysis (RDA).

Genetic structure, differentiation, and slight evidence for no selective neutrality of some SSR markers in populations of Medicago ciliaris (L.) Krock and Medicago intertexta (L.) Mill species

Medicago ciliaris (L.) Krock and Medicago intertexta (L.) Mill are most often found in saline regions and are considered as potential resources for genes related to salinity resistance. To explore the genetic diversity of these two species by mean of nrSSR (simplesequence repeats) markers, 11 accessions originated from different regions in north of Africa and Middle East were chosen. Ten among 14 markers turned out to be polymorphic and gave 72 alleles. Eight markers were very informative with PIC values > 0.5, and three of them were found to be nonneutral.

What a Waste: Solid Waste Management in Asia

The feedback from oil prices to economic activity is captured by a reduced-form production function that allows us to separately specify shocks to the output gap (transitory shocks to output), shocks to potential output (permanent shocks to the level of output), and shocks to potential output growth (permanent shocks to the growth rate of output). The richness of this speciﬁcation helps us to model the complicated interactions of oil price movements and GDP, where both trend and gap decline if oil prices increase.
