Content available Impact of the COVID-19 pandemic disruptions on container transport

The COVID-19 pandemic caused unprecedented disruptions in the global economy, and container transport as a predominant means of the goods flow in global supply chains. Different measures employed worldwide to limit the virus spread, such as restrictions and quarantines on border crossings, port staff, container ships, transhipment terminals and the inland transport sector, created a colossal management challenge and caused a domino effect in delays. Consequently, it led to blank sailings and enormous rises in freight transport prices, the lack of supply reliability and shifts between different means of transport. These delays, enhanced by the Suez Canal blockage, exacerbated an already acute problem of the empty container shortage in the market. This paper aims to provide an in-depth overview of the COVID-19 pandemic’s impact on container transport and underline ways to increase resiliency against future disruptions. The research included a literature overview and formulation of recommendations. The paper contributes to the broad research of container transport management and provides insights for practitioners responsible for transport planning and disruption management.

Pierwszy tunel pod Kanałem Sueskim oddano do użytku jeszcze w 1981 r. Po 37 latach Egipt doczekał się otwarcia dwóch tuneli, a rok później kolejnych dwóch. W 2020 r. wydrążono jeszcze jeden obiekt, którym przejazd będzie możliwy w 2021 r.

Zooplankton composition and abundance were investigated seasonally at ten sites in Lake Timsah and the adjacent, connected western lagoon in relation to the physico-chemical conditions. A total of 42 taxa (including larval stages) were identified, among them 21 species of copepods, 6 rotifers, 5 cladocerans, 1 chaetognath and 1 urochordate. Copepods represented the predominant component (77.7% of the total community), followed by rotifers, molluscs, cladocerans and (9.2, 4.7 and 3.9% respectively), while other groups collectively formed about 4.5% of the total zooplankton population. Summer was the most productive season with an average count of 40 864 individuals m-3. The dominant copepod species were Paracalanus crassirostris and Oithona nana representing 28.3 and 24.3% of the total zooplankton respectively. The total zooplankton count, including copepods, and its dominant species showed significant positive correlations with temperature, pH and total phytoplankton density. However, negative correlations were detected between densities of rotifers, and salinity and dissolved oxygen.

Will the political crisis in Egypt threaten sea transport?

The Suez Canal which was built due to the reduction of the transit distance between the North Atlantic and the Indian Ocean lies on one of the most important sea routes in the world. It has been rebuilt for several times just as ships have grown in size and capacity over the years. Suezmax ships are the maximum-sized tankers or container ships which can sail through the canal. Their deadweight is from 125 000 to 240 000 tons. Since its opening in 1869 it has been closed twice due to two war conflicts (the Suez Crisis and the Six-Day War). The closures influenced the direction of transport flows in sea transport and the size and capacity of ships.

Content available remote Effect of transplantation on heavy metal concentrations in commercial clams of Lake Timsah, Suez Canal, Egypt

Ruditapes decussatus and Venerupis pullastra are commercially fished clams with a wide distribution in the shallow inshore waters of Lake Timsah, Egypt. They are usually contaminated with heavy metals. Consumption of such contaminated clams can pose a public health risk. To minimise this risk, therefore, the clams should be removed from the contaminated waters and transferred to an approved area to reduce the high levels of metals before being marketed. The aim of this work was to study the effect of transplantation on levels of heavy metals (Fe, Mn, Zn, Cu, Ni, Co, Cd, Pb) in these clams. The clams were removed from their polluted site and transplanted to a relatively clean area for a period of 120 days. Although the salinity at the transplantation site was higher than at the polluted site, it was stable and did not appear to have any adverse effect on clam growth. Heavy metals were analysed in the water, sediment and clam tissues from both the polluted and the transplantation sites. Although in both species transplantation evidently reduced heavy metal levels, these still exceeded the maximum permissible levels laid down by the WHO (1982).

Content available remote Distribution of the sea squirt Ecteinascidia thurstoni Herdman, 1890 (Ascidiacea: Perophoridae) along Suez Canal and Egyptian Red Sea coasts

Ecteinascidia thurstoni is a colonial sea squirt. It has a seasonal rhythm and a tropical and subtropical distribution; it is usually present during the summer months. It synthesizes a group of molecules called ecteinascidins. One of these is ET-743, a compound that has a most original anti-tumoral activity and is today considered to be one of the most promising substances effective against various solid-type tumors (currently sold under the trade name of Yondelis for the treatment of sarcomas and related tumors; it is undergoing phase II/III clinical trails for other kinds of tumors). Worldwide, Ecteinascidia species represent the only available source of this bioactive compound, which was first discovered in E. turbinata. During the present study, the ecology of E. thurstoni along the Suez Canal and Red Sea was investigated. Its populations were observed to be highly gregarious due in part to their low larval dispersal, which is very localized; larvae therefore tend to settle close to their parent colonies. It is only recorded in shallow waters (0.5-1.5 m) as an epiphyte on the pneumatophores of mangroves by the Red Sea, on the pilings of jetties, and the metal or cement banks of the Suez Canal. The morphometric characteristics (zooid length, zooid weight, colony weight) of the Suez Canal population differ significantly from those of the Red Sea. Studying the distribution of this species and locating its different populations along the Suez Canal and Red Sea could help to characterize their genetics, chemistry and bacterial communities at different isolated locations. Ultimately, this will help to define the sources of ET-743 and hence promote its biosynthesis on a commercial scale.
