    Beschreibung: It is usually assumed that metabolic constraints restrict deep-sea corals to cold-water habitats, with ‘deep-sea’ and ‘cold-water’ corals often used as synonymous. Here we report on the first measurements of biological characters of deep-sea corals from the central Red Sea, where they occur at temperatures exceeding 20°C in highly oligotrophic and oxygen-limited waters. Low respiration rates, low calcification rates, and minimized tissue cover indicate that a reduced metabolism is one of the key adaptations to prevailing environmental conditions. We investigated four sites and encountered six species of which at least two appear to be undescribed. One species is previously reported from the Red Sea but occurs in deep cold waters outside the Red Sea raising interesting questions about presumed environmental constraints for other deep-sea corals. Our findings suggest that the present understanding of deep-sea coral persistence and resilience needs to be revisited.

    The intertropical convergence zone modulates intense hurricane strikes on the western North Atlantic margin (2016)

    Beschreibung: Most Atlantic hurricanes form in the Main Development Region between 9°N to 20°N along the northern edge of the Intertropical Convergence Zone (ITCZ). Previous research has suggested that meridional shifts in the ITCZ position on geologic timescales can modulate hurricane activity, but continuous and long-term storm records are needed from multiple sites to assess this hypothesis. Here we present a 3000 year record of intense hurricane strikes in the northern Bahamas (Abaco Island) based on overwash deposits in a coastal sinkhole, which indicates that the ITCZ has likely helped modulate intense hurricane strikes on the western North Atlantic margin on millennial to centennial-scales. The new reconstruction closely matches a previous reconstruction from Puerto Rico, and documents a period of elevated intense hurricane activity on the western North Atlantic margin from 2500 to 1000 years ago when paleo precipitation proxies suggest that the ITCZ occupied a more northern position. Considering that anthropogenic warming is predicted to be focused in the northern hemisphere in the coming century, these results provide a prehistoric analog that an attendant northern ITCZ shift in the future may again return the western North Atlantic margin to an active hurricane interval.

    Beschreibung: One of the main tasks of modern genetics is the study of the genetic diversity of organisms of different taxonomic levels. Such genome studies can serve as a tool for solving problems associated with identifying the evolutionary mechanisms by which genetic diversity has emerged. Discussions are still ongoing on micro- and macroevolutionary processes that can lead to a variety of genes and taxonomic diversity in the species of the Prussian carp Carassius auratus gibelio Bloch. It should also be noted that these studies have started relatively recently, and many questions concerning the genetic research of carp are still open.
    Beschreibung: Одной из основных задач современной генетики является изучение генетического разнообразия организмов различного таксономического уровня. Такие исследования геномов могут послужить инструментом для решения проблем, связанных с выявлением эволюционных механизмов, с помощью которых появилось генетическое разнообразие. До сих пор ведутся дискуссии относительно микро- и макроэволюционных процессов, которые могут приводить к разнообразию генов и таксономическому разнообразию у видов серебряного карася Carassius auratus gibelio Bloch. Также нужно отметить то, что данные исследования начались относительно недавно, и многие вопросы, касающиеся генетических исследований карася, остаются открытыми.

    Improvement of fish farming conditions (aquaculture) by cleaning and deepening fish passages and breeding reservoirs (2019)
    Azov Sea Research Fisheries Institute (AzNIIRKH) | Rostov-on-Don, Russia
    Details
    Publikationsdatum: 2021-05-19
    Beschreibung: The main activities of the fishery complex of the Rostov Region are fish breeding (aquaculture), fishing and fish processing. Anthropogenic impact on ecosystems of the Rostov Region negatively influenced fish industry, which led to reduction of spawning stock and deterioration of habitat and conditions for reproduction. Carrying out meliorative works by cleaning and deepening of fish passages and breeding reservoirs promotes restoration of natural spawning areas of commercial fish species and increases productivity and efficiency of spawning.
    Beschreibung: Основными направлениями деятельности рыбохозяйственного комплекса Ростовской области являются рыбоводство (аквакультура), рыболовство и рыбопереработка. Антропогенное воздействие на экосистемы Ростовской области негативно повлияло на рыбное хозяйство, что привело к сокращению нерестового фонда, ухудшению условий размножения и выживания. Проведение мелиоративных работ путем очистки и углубления рыбоводных каналов и водоемов способствует восстановлению естественных нерестилищ промысловых видов рыб, увеличению урожайности и продуктивности.

    Publikationsdatum: 2021-05-19
    Beschreibung: In the past two decades, interest in harvesting of fodder crustaceans and other bioresources of aquatic origin has grown significantly. Harvesting of aquatic invertebrates for aquarium fish culture on commercial scale began to be carried out relatively recently. The purpose of this work is to characterize the state of some brackish water reservoirs in the Volchikhinsky and Rubtsovsky Districts of the Altai Region and assess the stocks of their aquatic biological resources. During the research, it was found out that the water in the lakes of the Volchikhinsky District is: in Large and Small Gor'kaya Voda Lakes — of the sulfate class, in the Lake Chernyazhye — of chloride class, sodium group; in the Lake Korostelevskoe of the Rubtsovsky District — of hydrocarbonate class, sodium group. The main mass of phytoplankton in the lakes is green and blue-green algae. Zooplankton of the lakes of the Volchikhinsky and Rubtsovsky Districts is of the copepods-cladocera type with a significant predominance of the cladocera. The basis of zoobenthos in lakes is formed by chironomids.
    Beschreibung: В последние два десятилетия интерес к заготовке кормовых ракообразных и других биоресурсов водного происхождения значительно вырос. Заготовка водных беспозвоночных для аквариумного рыбоводства в производственных масштабах стала осуществляться сравнительно недавно. Цель данной работы охарактеризовать состояние некоторых солоноватоводных водоемов Волчихинского и Рубцовского районов Алтайского края и дать оценку запасов их водных биологических ресурсов. В ходе исследований отмечено, что в озерах Волчихинского района Большое и Малое Горькое вода сульфатного класса, в озере Черняжье — хлоридного класса, группы натрия; в озере Коростелевское Рубцовского района вода гидрокарбонатного класса, группы натрия. Основную массу фитопланктона в озерах составляют зеленые и синезеленые водоросли. Зоопланктон озер Волчихинского и Рубцовского района копеподно-кладоцерного типа со значительным преобладанием кладоцер. Основу зообентоса озер образуют хирономиды.

    Beschreibung: The bloom-forming cyanobacteria Trichodesmium contribute up to 30% to the total fixed nitrogen in the global oceans and thereby drive substantial productivity. On an expedition in the Gulf of Mexico, we observed and sampled surface slicks, some of which included dense blooms of Trichodesmium erythraeum. These bloom samples contained abundant and atypical free fatty acids, identified here as 2-methyldecanoic acid and 2-methyldodecanoic acid. The high abundance and unusual branching pattern of these compounds suggest that they may play a specific role in this globally important organism.

    CO2 and fire influence tropical ecosystem stability in response to climate change (2016)

    Beschreibung: Interactions between climate, fire and CO2 are believed to play a crucial role in controlling the distributions of tropical woodlands and savannas, but our understanding of these processes is limited by the paucity of data from undisturbed tropical ecosystems. Here we use a 28,000-year integrated record of vegetation, climate and fire from West Africa to examine the role of these interactions on tropical ecosystem stability. We find that increased aridity between 28–15 kyr B.P. led to the widespread expansion of tropical grasslands, but that frequent fires and low CO2 played a crucial role in stabilizing these ecosystems, even as humidity changed. This resulted in an unstable ecosystem state, which transitioned abruptly from grassland to woodlands as gradual changes in CO2 and fire shifted the balance in favor of woody plants. Since then, high atmospheric CO2 has stabilized tropical forests by promoting woody plant growth, despite increased aridity. Our results indicate that the interactions between climate, CO2 and fire can make tropical ecosystems more resilient to change, but that these systems are dynamically unstable and potentially susceptible to abrupt shifts between woodland and grassland dominated states in the future.
