Sudden Decrease

Black kites used the biggest waste dump of Turin for trophic purposes also during their reproductive months. After the dump closure there has been a sudden decrease in breeding pairs all over the area. During the following years the number of nests settled again however the small colonies trend was more scattered than before the landfill was closed.

Abstract Between 1984 and 2017, 1,388 Black Kites were recorded, mostly in lowlands with 70% of observations made at Dravsko polje. They were observed from sea level to around 1,600 m a.s.l. with an average elevation of 271 m a.s.l. The species was present in Slovenia from mid-March to early December with indistinct spring and autumn migrations. The highest number of observations was recorded in May. The Black Kite was observed in 71 out of 238 10x10 km grid squares in Slovenia (29.8%), with more observations around known breeding sites and at sites with higher observer effort. Both the number of observations and the number of probable and confirmed breeding pairs increased. In 2011–2018, 10 breeding pairs were found at 7 sites (3–7 per year). Additionally, 11 probable breeding pairs at 9 sites (0–6 pairs per year) were found. The breeding population in 2011–2018 is estimated at 10–21 pairs with an average breeding density of 0.3–0.9 breeding pairs per 100 km2. The highest density was recorded at Dravsko polje with 0.6–2.2 breeding pairs per 100 km2. If possible breeding (breeding attempts) were also taken into consideration, the estimate would be up to five breeding pairs higher. The species was recorded at known breeding sites in most years after the breeding was confirmed. Black Kites were observed closer to larger water bodies and to rubbish tips than expected by chance. More Black Kites were recorded in areas with a lower percentage of forest and arable land and a higher percentage of meadows, settlements and wetlands.

[The breeding of the Red-crested pochard in Piedmont is known since 2006, when it was first described in a pond near the town of Asti. Data were collected from specific databases and from field observations performed in 3 sites located in the Asti province and 2 sites in the Cuneo province, all of them placed along the Tanaro riversides. A further site is located in the province of Alessandria near the Po river along the border of Lombardy. On the whole, in the time span 2006-2019 the number of breeding pairs increased from 2 to a maximum of 7 per year. A total of 64 females with 326 chicks were recorded (average 5.1/female), June being the most favorable month for reproduction. Results point to the occurrence of a seemingly stable small breeding population. The lack of any kind of legal site protection, the anthropogenic disturbance (hunting, fishing, abandoning wastes), and the loss of the ideal habitat for reproduction are among the critical threats for the maintenance of a vital breeding population. There was a probable case of nest parasitism by Mallard duck, which is seldom observed since the opposite situation seems to be more common.]   [Article in Italian]

<p>All-solid-state batteries are promising candidates for next-generation energy storage devices. Although the list of candidate materials for solid electrolytes has grown in the past decade, there are still many open questions concerning the mechanisms behind ionic migration in materials. In particular, the lithium thiophosphate family of materials has shown very promising properties for solid-state battery applications. Recently, the Ge-substituted Li<sub>6</sub>PS<sub>5</sub>I argyrodite was shown to be a very fast Li-ion conductor, despite the poor ionic conductivity of the unsubstituted Li<sub>6</sub>PS<sub>5</sub>I. Therein, the conductivity was enhanced by over three orders of magnitude due to the emergence of I<sup>−</sup>/S<sup>2−</sup>exchange, <i>i.e.</i>site-disorder, which led to a sudden decrease of the activation barrier with a concurrent flattening of the energy landscapes. Inspired by this work, two series of elemental substitutions in Li<sub>6+<i>x</i></sub>P<sub>1−<i>x</i></sub><i>M<sub>x</sub></i>S<sub>5</sub>I (<i>M</i>= Si and Sn) were investigated in this study and compared to the Ge-analogue. A sharp reduction in the activation energy was observed at the same <i>M</i><sup>4+</sup>/P<sup>5+</sup>composition as previously found in the Ge-analogue, suggesting a more general mechanism at play. Furthermore, structural analyses with X-ray and neutron diffraction indicate that similar changes in the Li-sublattice occur despite a significant variation in the size of the substituents, suggesting that in the argyrodites, the lithium substructure is most likely influenced by the occurring Li<sup>+</sup>– Li<sup>+</sup>interactions. This work provides further evidence that the energy landscape of ionic conductors can be tailored by inducing local disorder.</p>

AbstractGenome-wide selection (GWS) has been becoming an essential tool in the genetic breeding of long-life species, as it increases the gain per time unit. This study had a hypothesis that GWS is a tool that can decrease the breeding cycle in Jatropha. Our objective was to compare GWS with phenotypic selection in terms of accuracy and efficiency over three harvests. Models were developed throughout the harvests to evaluate their applicability in predicting genetic values in later harvests. For this purpose, 386 individuals of the breeding population obtained from crossings between 42 parents were evaluated. The population was evaluated in random block design, with six replicates over three harvests. The genetic effects of markers were predicted in the population using 811 SNP's markers with call rate = 95% and minor allele frequency (MAF) > 4%. GWS enables gains of 108 to 346% over the phenotypic selection, with a 50% reduction in the selection cycle. This technique has potential for the Jatropha breeding since it allows the accurate obtaining of GEBV and higher efficiency compared to the phenotypic selection by reducing the time necessary to complete the selection cycle. In order to apply GWS in the first harvests, a large number of individuals in the breeding population are needed. In the case of few individuals in the population, it is recommended to perform a larger number of harvests.

Conceptual Research

The conceptual research aims to identify antecedents conducive to bilateral trade during the COVID-19 pandemic. Considering the relevance of bilateral trade for foreign policy and economy studies, there is a need for a renewed framework in times of extreme economic instability. As international commerce is essential for improving the country’s economy, we have examined how economic distance, population, trade percentage of GDP, exchange rate, and political changes interconnect and relate to COVID-19, influencing trade flows. This conceptual paper illustrates the likely impact of COVID-19 on international trade by exploring pandemics’ effects on standard trading parameters such as GDP, distance, policy stability, and population. We model the resulting shock as a multifaceted variable reflected in capital underutilization, manufacturing output decline, international trade costs inflation, production costs inflation, decrease in demand for certain services and shift from everyday needs towards activities that exclude the proximity between people, e.g., proclivity towards virtual market products. The sudden decrease in GDP and bilateral trade, as well as FDI, is amplified by further development of pandemics’ long-term consequences. We take COVID-19 to be a technological, financial, and policy shock significantly influencing international trade and economic development and argue that it will have a varying impact on diverse sectors and economies. The paper offers preliminary insight into the pandemic-related economics that are unfolding and deduce recommendations on positive changes in trading policy to fully leverage on arising trading opportunities and point to potential research directions.
