Assessing the Impact of Substrate and Shelter on Cannibalism in Blue Swimming Crab (Portunus pelagicus)

Blue swimming crab (Portunus pelagicus) is one of Indonesia’s essential fishery commodities, but overfishing has depleted its population. Aquaculture, as an alternative to produce this crab, is hampered by high levels of cannibalism. Substrates or shelters can reduce cannibalism. This study compared the effectiveness of one substrate and two types of shelter for reducing cannibalism of P. pelagicus crablets. Crablets with average carapace length of 3.6 ± 2.2 cm and average weight of 6.4 ±1.5 g.ind-1 were stocked in 24 rectangular tarpaulin tanks with 1 m2 surface and 50 cm water depth. The stocking density was 8 crablets in each tank. A split-plot experimental design was applied with four main plots and two subplots with 3 replications. The main plot consisted of A0 (without shelter), A1 (seaweed), A2 (pipes), and A3 (seaweed and pipes), and sub-plots had either no-substrate (B0) or sand-substrate (B1). Cannibalism (K), survival (S), and four water quality parameters were recorded for 42 days. The data were analyzed using an ANOVA for a split-plot design and post-hoc Tukey. The results show that the sand substrate significantly (P>0.05) reduced cannibalism and increased survival of the P. pelagicus. Treatment A0B0, without substrate or shelter, showed the highest cannibalism (54±7%) and lowest survival rates (33±7%). While treatment A1B1, with Gracillaria sp. as shelter and sand as bottom-substrate resulted in the lowest cannibalism (4±7%) and highest survival rates (88±13%).

Displaced juvenile and subadult Caribbean spiny lobsters show strong orientation toward home dens

Caribbean spiny lobsters are known to undergo migration as adults, but the dispersal and homing ability of subadults and juveniles is not well characterized. Given that settlement habitat for juveniles is inshore seagrass / hardbottom and reproductive habitat is offshore coral reefs, dispersal during ontogeny serves as a bottleneck potentially limiting adult population density. Previous studies have examined factors associated with movement and den selection by juvenile lobsters such as shelter type, predators, and conspecific density. Their attraction to odors of healthy conspecifics plays a significant role in aggregation of lobsters in casitas and traps. But what is unknown is whether juvenile lobsters possess the map and compass orientation found in adults. To examine the ontogeny of homing ability, we conducted multiple mark / displace tracking studies using acoustic telemetry in juvenile hardbottom and subadult coral patch reef habitats. All lobsters regardless of size tend to relocate to new crevice shelters when handled, even if returned to their original shelter. Thus, for non-displaced lobsters tagged and returned to their point of capture, distance and angle travelled appears to be random with distance increasing as function of body size. However, for juvenile and subadult lobsters tagged and displaced away from their point of capture, the distance and angle travelled when released is significantly directed toward the point of capture. Thus, it appears that the map and compass ability of Caribbean spiny lobsters appears early in ontogeny and may allow for individuals to safely explore unfamiliar locations while retaining knowledge of how to return to known shelter. This ability to expand their known habitat map while maintaining knowledge of critical diurnal shelter locations is expected to facilitate their ontogenetic dispersal to adult habitat.

Examination of dairy cattle farms in Burdur province in terms of animal welfare

This study aims to assess the status of dairy cattle farms in Burdur province with regard to animal welfare. A total of 56 dairy cattle farms were visited, and face-to-face interviews were conducted with owners. Findings revealed that 32.1% of dairy cattle breeders had received vocational training, with 19.6% having undergone training solely in animal nutrition, and 12.5% possessing information and training specifically related to animal welfare. Most breeders (91.1%) preferred the semi-open shelter type and the eastern direction (67.9%) as the long-axis direction. Concrete was preferred construction material for shelter bases in the majority of cases (98.2%). However, it was noted that certain aspects crucial to animal welfare, such as the loading ramp, vaccination route, and urinary tract, were not adequately incorporated into the planning process. Manure cleaning was typically performed every six months (32.1%), with 60.7% utilizing a tractor for assistance. In the observations made, it was determined that the cows had hoof problems (53.6%) and lameness was low (33.9%). It was determined that the legs (44.0%), thighs (44.9%), and udder-abdomen area (44.2%) of the cows were dirty. It was determined that cows had an average body condition score of 2.25-3.5 (38.9%) and a rumen fill score of 3 (38.1%). It was determined that the cows had easy access to water and were fed in two meals (91.1%) in the morning and evening. The results showed deficiencies regarding animal welfare in the planning and management of shelters in dairy cattle farms in Burdur province.

THE SNAKES IN CAPTIVITY

Reptiles can now adapt to different types of food and shelter because they have evolved to withstand the uncertain environment. It is crucial to recognize the similarities between the human world and the captivity-dwelling snakes because they now bear similarities to the human empire. The significance of creating a snake enclosure for the reptiles is also discussed in this piece. Additionally, some of the most important elements that must be taken into account when designing the enclosure are covered in this article.

Multi-criteria comparison analysis of spatial equity for emergency shelters in old and new urban districts: A case study in Wuhua District and Chenggong District of Kunming City, China

With the progression of urbanization and the concentration of populations in urban areas, cities are increasingly exposed to disaster risks. Emergency shelters play a critical role in disaster prevention and mitigation, as they are vital for providing temporary refuge and protection during and after catastrophic events. Assessing the spatial equity of these shelters is conducive to enhancing emergency relief capabilities and aiding in disaster risk reduction. However, there remains a lack of clarity regarding the comparative and quantitative disparities between new and old urban areas, particularly in developing countries like China, where urbanization is rapid and populations are dense. To address this issue, this study employed a combination of multi-source data and GIScience technology to analyze the spatial equity of emergency shelters in Wuhua District and Chenggong District of Kunming City, China. We evaluated the overall spatial equity of emergency shelters in both the old urban area (Wuhua District) and the new urban area (Chenggong District) using a comprehensive evaluation model with three criteria: evacuation population capacity, spatial accessibility, and the level of per capita effective shelter area. The results revealed that the old urban area suffers from insufficient effective emergency shelter capacity due to saturated construction land. More than 67 % of the shelters are short-term emergency shelters located close to buildings, which compromises spatial accessibility during earthquake disasters. The level of per capita effective shelter area, as indicated by SSTD, is 24.42 in Wuhua District, suggesting that the effective shelter area in each subdistrict is consistently low, regardless of its urban or suburban classification. In contrast, the new urban district boasts substantial effective emergency shelter capacities, both in the long-term and short-term types, surpassing the reference capacities. The rational spatial layout of various types of emergency shelters ensures that most regions with concentrated buildings are enveloped in accessibility time layers within a 25-min range. The SSTD index of Chenggong District is 349.23, underscoring the significant disparity in the level of per capita effective shelter area at the subdistrict scale, particularly in the district's urban villages and suburban regions. The findings of this study serve as a scientific reference for emergency management and urban planners to reasonably plan or upgrade shelter facilities, thereby improving urban resilience and promoting spatial equity in resource allocation among subdistricts, communities, and residents.

The Establishment Of Shelters as A New Paradigm Towards Struggling With Violence Against Women: A Literature Review.

Shelters are an important part of a full response to survivors, as stated in many international conventions, such as the 1995 Beijing Declaration and Platform for Action (BDPfA). This study aims to provide a comprehensive perspective on the establishment of shelters for women survivors of violence. This narrative review was conducted based on the Scale for the Assessment of Narrative Review Articles (SANRA). The MEDLINE, SCOPUS, Web of Science, Embase, Ovid, and EBSCO databases in English and Magiran and Scientific Information Database (SID) in Persian were searched for related documents. Also, WHO, the Joint United Nations Programme on HIV and AIDS (UNAIDS), the Centers for Disease Control and Prevention (CDC), and the United Nations Population Fund's (UNFPA) guidelines and instructions for shelter services for women and girls who have been subjected were searched up to July 31, 2023. A qualitative synthesis was carried out on the 28 eligible articles and instructions out of the 420 retrieved documents. "A "shelter" describes emergency and temporary "safe accommodation for women and children who have been subjected to or are at risk of (typically male) domestic abuse. Types of shelters include emergency shelters or safe homes, second-stage or transitional housing facilities, third-stage housing, and alternative accommodation during (and occasionally after) the period of residence. The shelter delivers a wide range of services, including health services, socio-economic services, and legal services. These principles consisted of a comprehensive perspective, quality of service, organization, funding, and the right issues. Women who are survivors need holistic, interdisciplinary, and specialist care that focuses on safety and needs. The adoption of regulations with robust enforcement guarantees and the facilitation of approvals for the construction of non-governmental shelters and safe houses should be on the agenda setting.

Rural occupancy in a montane burrowing snake: the importance of thermal and microhabitat resources during the rainy season

Thermal and microhabitat resources are two fundamental requirements that affect the life history of any ectotherm. Furthering our understanding of how reptilian species meet these ecological requirements is crucial for assessing the impact of environmental and anthropogenic changes on populations. Here, we explored some fundamental aspects of the thermal and microhabitat ecology of Conopsis biserialis, a small, burrowing, and endemic earthsnake of central Mexico. The study was conducted during the rainy season in a montane site disturbed by rural activities. The mean field body temperature (Tb) of C. biserialis was 26 ± 0.6 ºC. Field Tb did not differ significantly between sex and development stages. However, we found that Tb was positively correlated with substrate, air, and under-rock temperatures (Ts, Ta, and Tr) in the rural microhabitat. Regression analysis showed that substrate and under-rock temperatures (Ts and Tr) were the parameters that best explained Tb variability in the individuals. The temperature and relative humidity under shelter did not differ significantly among shelter types and/or rock sizes. In addition to these thermal traits, earthsnakes selected and utilized six common biotic and physical elements of the rural microhabitat. Most individuals used high proportions of large and medium rocks for sheltering, and these rocks were selected around crop fences and cleared grasslands where the soil can be either covered with low vegetation or bare. Our results suggest that, during the rainy season, individuals of C. biserialis use and select some biotic and structural resources of the rural microhabitats, and were capable of actively regulating their temperature by using shelters with high values of microclimatic homogeneity.

The Influence of Shelter Type and Coverage on Crayfish (Procambarus clarkii) Predation by Catfish (Silurus asotus): A Controlled Environment Study.

Procambarus clarkii is adept at using natural shelters and caves to evade attacks from predators. However, the concealment abilities and mechanisms of P. clarkii for different types of shelters under predation pressure have not yet been reported. In this study, laboratory experiments were carried out to determine the effects of different coverages (25%, 50%, and 75%) and different combinations (I-VII) of three types of shelters (PVC pipes, water grass, and stone) on the predation rhythm, behavior, and abilities of Silurus asotus on P. clarkii. The results indicated that the predation of S. asotus on P. clarkii exhibited significant rhythmicity under shelter conditions, excluding PVC pipes, 75% stone, and combination VI. Among the three types of shelters, PVC pipes provided the strongest concealment, followed by stone and water grass. With the increase in shelter coverage, the anti-predation ability of P. clarkii continued to increase, and the optimal shade rate for water grass was 50%. In the different shelter combinations, the environmental complexity had little effect on the predation activity of S. asotus on P. clarkii. These findings demonstrated that the type and abundance of shelters in the wild environment can affect the predation rhythm and activities of S. asotus on P. clarkii.

Investigating the Construction of a Post-earthquake Shelter Using the Super Adobe Method in Herat, Afghanistan

Earthquakes, as one of the most destructive natural disasters, have always posed significant challenges to humanity. The construction of temporary housing in post-earthquake conditions is very necessary and should be considered as a life-saving measure. To ensure the safety and health of the people affected by the earthquake, it is necessary to provide solutions for cheap, fast, and safe housing. Construction solutions for cheap and fast housing in times of crisis require the use of earthquake-resistant technologies. Among the types of post-earthquake temporary housing, housing construction using Super Adobe is one of the solutions that speed up the construction process and reduce costs. The purpose of this article is to investigate the need and construction of an emergency shelter using the Super Adobe method after the deadly earthquake in Herat, Afghanistan in 2023. The research paradigm is qualitative and comparative methods and logical analysis have been used in it. In the first part, the types of emergency shelters were compared and the construction of emergency shelters using the Super Adobe method in Herat was evaluated. Then 38 samples made in the Sanjab village of Herat were examined. The results of the research show that according to the geographical, economic, social, physical, and rural conditions of the region, the problems and challenges in the preparation of materials, and the construction of earthquake-resistant shelters, the Super Adobe method is the most suitable option for the construction of emergency shelters in this region. The ability to implement in a short time, the use of local materials, compatibility with the rural context, resistance to cold, heat, and climatic conditions of the region, resistance to earthquakes, low cost, and compatibility with sustainable rural development are the main reasons for the compatibility of this plan with the existing post-earthquake conditions.

Cинтетические укрытия вегетационных сооружений с интегрированным фотолюминофором в укоренении черенков туи западной

We have explored the effectiveness of using light-correcting covering materials for greenhouse structures when rooting the cuttings of various ornamental forms and varieties of the northern white-cedar (Thuja occidentalis L.). Two types of shelters have been tested: the modified spunbond at a density of 30 g/m2 with a photoluminescent phosphor integrated into its structure at a concentration of 0.8 % and the unmodified spunbond at the same density. Europeum-doped yttrium oxysulfide (Y2O2SEu) has been chosen as a photoluminescent phosphor. We have analyzed 11 varieties and forms of Thuja occidentalis L.: Rheingold, Mr. Bowling Ball, Woodwardii, Tiny Tim, Golden Smaragd, Mirjam, Golden Globe, Danica, Sunkist, Smaragd and Brabant. The response of the indicators of callusogenesis and rhizogenesis to the influence of a transformed light flux has been tested. A positive effect of the use of photoluminescent phosphors in rooting the stem cuttings of the northern white-cedar has been established. An increase in the indicators of regenerative ability and post-regenerative development of the root systems and the aboveground parts of the cuttings has been recorded, such as: the activity of callusogenesis, the number of adventitious roots formed, the length of the leading root, the total length of the root system, the height of the aboveground part and the diameter of the root collar. Callusogenesis has increased from 67.59 ± 2.05 % in the check to 76.81 ± 1.61 % when having integrated the photoluminescent phosphor. The number of adventitious roots formed has increased from 9.64 ± 0.43 to 11.44 ± 0.34 pcs., correspondingly. The total length of the root systems has increased from 64.56 ± 3.70 to 75.52 ± 2.77 cm, correspondingly. One-way analysis of variance confirmed the significance of the differences between the tested forms and varieties in each of the shelter options for most of the tested indicators. Two-way analysis of variance has revealed a significant effect of the positive impact of photoluminescent phosphors on callusogenesis, adventitious root formation, post-regenerative development of the root systems and the aboveground parts of the cuttings.

Effects of flow speed and prey density on the rate and efficiency of prey capture in zooplanktivorous coral-reef fishes

Holling’s classical functional response model describes the mechanistic foundations of the relationships between predation rate and prey density. As such, the model is pertinent to predators that actively search for prey, but not to stationary predators in which additional factors, such as flow speed, determine the rates of prey encounter. The main objective of this study was to measure the rates and corresponding efficiencies of zooplanktivory among different common species of coral-reef fishes under a wide range of prey densities and current speeds. All our experiments were carried out in a flume with different combinations of flow speeds (3-28.5 cm/s) and prey densities (210 - 1050 prey m-3). Nauplii of Artemia salina were used as prey. Despite major differences in the taxonomic origin of the studied species, their morphologies, and the types of shelters they use, the foraging performances of the fish, their predation rates, and the way those rates were affected by prey density and flow speed were surprisingly similar. Under a fixed prey density, capture rates did not change much as function of flow speed. Under conditions of equal prey flux, predation rates were always higher under conditions of high density and weaker flow than under lower density and faster flow. A sharp decline in capture efficiency with increasing flow speed was explained by a corresponding narrowing of the fish’s body orientation relative to the flow. In other words, with increasing flow speed, the fish gradually became more-narrowly oriented head-on onto the flow, exhibiting a decrease in the frequency of body turns (“maneuverability”). These trends, especially the reduced maneuverability under strong currents, can explain our findings that predation rates did not increase when the flow, hence prey flux, increased. Inter-specific differences in predation rates and efficiencies, however small, agree well with observed differences in the type of habitats the different species occupy.

Visceral leishmaniasis seroprevalence and associated sociocultural factors in an endemic area of Sergipe, northeastern Brazil

The present study aimed to investigate the presence of anti-Leishmania antibodies in samples of domiciled dogs and associate them with epidemiological indicators in the city of Lagarto, Sergipe. The diagnosis of Canine Visceral Leishmaniasis (CVL) was carried out in 755 dogs, where the rapid two-way platform immunochromatographic test (TR-DPP) (Fiocruz/Biomanguinhos) and the serological test of Enzyme-Linked Immunosorbent Assay (ELISA) were applied. The results showed that all homes with seroreactive dogs were close to abandoned land, squares and/or green areas. There was a significant association between seroactive animals and type of shelter (p=0.008); 54.8% had an indoor shelter and 45.2% of the dogs had a shelter outside their homes. The disease is geographically distributed in 14 (73.68%) of the 19 sample areas in the municipality. Of these, five (26.31%) had cases of Visceral Leishmaniasis in dogs and humans. Eight cases of Human Visceral Leishmaniasis (HVL) were reported during the years 2017 to 2020 in the municipality. Dogs that are located in areas of greatest risk impact the maintenance of natural foci of Leishmaniasis transmission to human and animal hosts in areas endemic for Visceral Leishmaniasis. Such results are essential to assist epidemiological surveillance in the municipality of Lagarto-SE with the implementation of control measures aimed at the insect vector of the disease, the sand fly, to prevent human and canine cases.

Capture of zooplankton by site-attached fish: striking dynamics under different flow speeds and prey paths

Consumption of pelagic zooplankton plays a vital role in the functioning of benthic communities such as coral reefs and kelp forests. Many fish that consume zooplankton in those habitats are site attached, foraging for drifting prey while maintaining a fixed position close to a shelter such as a branching coral or a perforated rock. Therefore, the flow, in which their planktonic prey drifts, is expected to affect their foraging movements. However, most attributes of those movements are poorly understood- a gap that our study seeks to fulfil. Our experiments were carried out in a laboratory flume with 4 common coral-reef site-attached species. Their movements were recorded in 3D, using two orthogonal video cameras. Different fishes exhibited similar trends despite noticeable differences in their body size, their morphology, the type of shelters they use, and the typical size of the groups in which they reside. In all species, the strike distance decreased with increasing flow speed. Similarly, the distance between the fish and prey at the moment of strike initiation (“Reactive Distance”) decreased with increasing flow speed, as well as the angle between that “Reactive Distance” and flow direction. Surprisingly, striking speeds (relative to Earth) remained nearly unchanged under different flows speeds. However, faster strikes occurred when oriented at wider angles relative to the flow. Taken together, the fish appear to determine the speed and angle of their strikes based on a cognitive ability to assess the prey’s drifting speed and path in order to reach on time the intercepting point. A rough estimate of the time it takes the fish to decide on the strike’s orientation and speed, would suggest a few hundred of milliseconds. Using published data on the fishes’ feeding rates, we found that the fish significantly differed in their feeding efficiencies, defined as the percent of prey they captured from those passing through their actual foraging space. That difference may explain inter-specific differences in the habitats the fish use and their group size.

Вухань австрійський (Plecotus austriacus) на Волині: новий поступ у експансії на сході Європи

The paper describes the discovery of a species from the group of sibling species of the superspecies Plecotus auritus (sensu lato), which has been showing a wide expansion in Eastern Europe over the past 100 years. Expansion is facilitated by the species’ pronounced synanthropy, with a particular preference for different types of artificial wintering shelters, which often leads to new finds. The new find is the second for the Volyn region of Ukraine and fills the gap between the known finds in Poland, south-western Belarus (Brest region) and neighbouring regions of Ukraine (Lviv and Rivne oblasts). The new find was recorded on 18.09.2021 in the village of Radovychi, Kovel Raion, in a cellar. The currently known finds of the species in the region are distributed fairly evenly in space and time, indicating a slow and wide expansion, without a significant increase in numbers.

Examining the Structural and Technical Characteristics of the Water Buffalo Farms in Sivas Province from the Perspective of Animal Welfare

In Turkey, water buffalo husbandry is conducted generally by using the traditional methods in shelters designed for cattle. The present study reports the data of the items of a questionnaire, which was conducted with 122 water buffalo breeders which are located in Central, Şarkışla, and Suşehri districts of Sivas province, regarding the structural and technical aspects of shelters such as shelter location, shelter type, building material, ventilation, and lighting. It was determined that, among the water buffalo breeders in Sivas province, the shelters were generally (73.5%) located nearby the house, that the building materials used in construction of the shelters were stone in 55.4%, concrete in 21.5% and briquette in 16.5% (p<0.0001), and that the floor materials used were concrete in 99.2% (p<0.05), whereas the roofing material was sheet metal/eternit in 80% (p<0.0001). It was found that water buffalos and cattle were held together in closed tethered systems (95.8%) and the space needs of animals were met by using chains having 40-60cm in length (63.1%). In conclusion, considering the animal welfare and behaviors, it was concluded that the infrastructural improvements to ensure the standardization in water buffalo shelters should be prioritized, that the old shelters should be re-organized, and that the watering systems in shelters should be analyzed.

Lessons from patch dynamics for ecology and restoration: The succulent Karoo, Sandveld example

A series of long-term field and glasshouse experiments were conducted in the semi-arid Sandveld Bioregion of southern Africa, across a wide range of post-mining site and soil conditions, on the two major plant groups, leaf-succulent shrubs (LSS, which establish in open micro-habitats) and non-succulent shrubs (NSS, which establish in sheltered micro-habitats). Seeding experiments applied a sequential ecological framework intended to reduce the impact of impeding natural ecological processes whilst incorporating processes that facilitate plant establishment. Experimental plots were scaled to naturally operating ecological dynamics at the patch scale, and various potentially facilitative types of shelter and soil amelioration, tested separately. Results are reported over three or six year periods and from four or seven field sites. Shelter generally had a greater effect on plant establishment than soil ameliorants, but this could be either positive or negative, and varied for the two plant groups: LSS establishment was inhibited or neutral under all forms of shelter, NSS were facilitated by types of artificial shelter that could be removed or biodegraded without impacting young plants. Both groups were strongly inhibited under transplanted nurse plants. Water absorbing gels improved LSS establishment but other soil ameliorants had no effect, while milled kelp or nutrients improved NSS establishment (measured as a biomass index or plant abundance, respectively). Finally, site had a greater effect than either shelter or soil ameliorants, and could not be related to any soil or other factors measured, supporting recent studies that explicitly quantify the substantial unknown effects of site and year. Specific recommendations are made for comprehensive, seed-based, nucleated restoration designs for the Sandveld and similar bioregions, while the over-arching results are of universal import to dryland restoration and ecology.

Use of Nest Shelters by American Common Eiders (Somateria mollissima dresseri): Occupancy Rates and Effects of Shelter Type on Nest Microclimate

Зимiвля східної субтропiчної прiсноводної креветки (Macrobrachium nipponense dе Haan, 1849) в умовах басейну р. Днiстер

Purpose. To study the characteristics of wintering of Macrobrachium nipponense in natural conditions of the Lower Dniester basin and experimental assessment of the effect of physical condition, soil composition and type of shelter on the survival of wintering shrimps. Methodology. The results of field and experimental studies conducted in 2018–2020 were used in the study. The locations and conditions of mass wintering of shrimps in natural conditions in the lower reaches of the Dniester River were studied. The abundance of wintering individuals was determined by the method of direct counting and their physical condition was analyzed. Shrimps were kept in a RAS at the Laboratory of Aquatic Bioresources and Aquaculture of Odesa State Ecological University, where environmental parameters were maintained as close as possible to the conditions of wintering under natural conditions. In chronic experiments, the selectivity and effect of the composition of natural substrates and the thickness of the soil bed on shrimp survival were investigated. The selection and effectiveness of the shrimp’s use of above-ground shelters of various natural and anthropogenic origin for shrimp wintering was assessed depending on their physical condition (presence or absence of injuries). Shrimp for experiments were caught in October - November in the lower reaches of the Dniester River and the Dniester estuary. The location of mass wintering of shrimps was recorded using a GPS navigator. Findings. It was established that shrimp M. nipponense in natural conditions of the Lower Dniester river winters in aboveground shelters (of natural and anthropogenic origin) or by burrowing into the soil. The shrimp’s choice of aboveground shelters for wintering in natural conditions depended on their physical condition. Injured individuals (lost claws and limbs) preferred easily accessible aboveground shelters (sheaves of grass, flooded snags). Healthy individuals wintered in cracks between plant roots and stones. A significant part of shrimps overwintered in aboveground shelters of anthropogenic origin. The most complex and reliable aboveground shelters of natural origin were occupied by the least damaged shrimp individuals. More than 59% of shrimps are buried in the soil (soil shelters) for wintering. Healthy individuals prefer sandy soils or soils that contain sand. The highest yield of healthy shrimp overwintering was observed on sandy or sandy-gravel soils with a thicker soil layer. The depth of burial of shrimp depended on soil composition. It was the maximum in soils consisting of sand, sand-gravel mixture and chernozem or chernozem with inclusions of gravel. The survival of wintering individuals was inversely dependent on the depth of burial. The maximum yield of uninjured individuals from wintering was observed when they were buried in the soil, the minimum — when using aboveground shelters. The share of surviving injured shrimp in soil shelters decreased in proportion to the severity of the injury. Maximum survival of injured individuals was ensured by wintering in aboveground shelters. Originality. For the first time, the data of field observations on wintering of alien shrimp M. nipponense in the conditions of the Lower Dniester basin are presented. Locations and conditions of mass wintering in natural conditions have been established. As a result of experimental studies, an analysis of the selectivity and effectiveness of the use of soil and aboveground shelters of various natural and anthropogenic origins by shrimp during wintering, their selectivity depending on the physical condition of wintering individuals (presence or absence of injuries) is given. Practical value. In the conditions of progressive climatic changes, one of the urgent tasks is the acclimatization of promising objects of aquaculture in new natural ecosystems. The obtained results can be used for the development of methods of anthropogenic reproduction and controlled cultivation of shrimp M. nipponense in aquaculture in the south of Ukraine. Key words: Dniester River, Macrobrachium nipponense, wintering, aboveground shelters, ground shelters, physical condition of individuals, survival.

Material and construction solutions in the construction of civil defence shelters

An analysis is presented of the use of material and construction solutions used in construction, mainly residential, for the construction of OC (civil defence) shelters.The article presents procedures for designing reinforced concrete structures that make it possible to properly determine the load capacity of critical sections. In the present work, a study of the deformation stability of a zone of reinforced concrete sections that is subjected to compression is used. Computational methods based on Drucker's postulate were used to solve the problem. The proposed approach enables the determination of the values of ultimate and failure strains based on the analysis of the loading path of a reinforced concrete section.Generally, shelters built into residential buildings are analysed, intended to be constructed in the rooms of the basement floor. A reduced need for ancillary space, the basement room, is observed. Garage functions are located on the basement floor. The plan contours of the basement are often larger than those of the ground floor. It is possible to design a shelter for the residents of the building, which ensures the greatest efficiency in its use. It is desirable to maintain uniform material and construction solutions while maintaining technological and organisational solutions during the erection of the entire building.The paper indicates the possibility of using some of the material and structural solutions of the housing construction in the realisation of OC shelters built into the basement floor. The construction of free-standing shelters was not analysed separately, but the proposals presented in the paper can also be applied to the type of OC shelters. Some results of the analysis of the adaptation of material and structural solutions of the housing construction to the needs of OC shelters construction will be presented during the symposium.It is advisable to develop models for the construction of OC shelters using contemporary technologies used in the construction industry.Useful tool can be the proposed scheme for improving activities based on the EFQM model.
