isogeniclines, etc ; evolution; spatial data; urbanization; Show all 4 Subjects
Abstract:
... Historical road data are often needed for different purposes, such as tracking the evolution of road networks, spatial data integration, and urban sprawl investigation. However, road extraction from historical maps is challenging due to their dissatisfying quality, the difficulty in distinguishing road symbols from those of other features (e.g., isolines, streams), etc. Recently, although deep lea ...

Abstract:
... A tendency to return to the natal/breeding site, ‘philopatry’, is widespread amongst migratory birds. It has been suggested that a magnetic ‘map’ could underpin such movements, though it is unclear how a magnetic map might be impacted by gradual drift in the Earth’s magnetic field (‘secular variation’). Here, using the International Geomagnetic Reference Field, we quantified how secular variation ...

Abstract:
... It is assumed that the crystallographic texture of minerals in the shells of recent and fossil mollusks is very stable. To check this, it is necessary to examine the shells of animals that had lain in sediments for millions of years and lived in different conditions. It is revealed that the crystallographic texture of calcite in the shells of Gryphaea dilatata from deposits from the Middle Callovi ...

Abstract:
... Tephra fallout hazard assessment is undertaken with probabilistic maps that rely on numerical models. Regarding maps production, the input parameters of the model (including atmospheric conditions), the physical approximations of the numerical simulations, and the probabilities of occurrence of different eruption types in specific time frames are among the most critical sources of uncertainty. We ...

Abstract:
... Stem borers are major insect pests of maize in Uganda. A study was conducted in 2014–2016 to assess the performance of Bt hybrids expressing Cry1Ab (event MON810) against the two major stem borer species in Uganda – the African stem borer (Busseola fusca) and the spotted stem borer (Chilo partellus) – under artificial infestation. The study comprised 14 non-commercialized hybrids, including seven ...

Abstract:
... Measurements of the tracers, ¹²⁹I, CFC‐11, and SF₆ on water samples collected in the Arctic Ocean in 2015 have been used to calculate mean ages, Γ and mixing, Δ parameters using transit time distributions (TTDs) to constrain water circulation and mixing time scales. Values of Γ and Δ determined separately using the two tracer pairs, SF₆‐CFC‐11, and ¹²⁹I‐CFC‐11 are in good agreement for gas solubil ...
... Common wheat (Triticum aestivum L.) is the most important crop in the world and a typical allopolyploid with a large and complex genome. Pre-harvest sprouting (PHS) leads to a significant reduction in grain quality worldwide. PHS is a complex trait with related QTL located on different chromosomes. However, the study of markers and genes related to PHS resistance is limited especially for white-gr ...

Abstract:
... Soybean is one of the most important food crops worldwide. Like other legumes, soybean can form symbiotic relationships with Rhizobium species. Nitrogen fixation of soybean via its symbiosis with Rhizobium is pivotal for sustainable agriculture. Type III effectors (T3Es) are essential regulators of the establishment of the symbiosis, and nodule number is a feature of nitrogen-affected nodulation. ...

Abstract:
... In present paper, we consider the impact of blast-induced vibrations on constructions by analyzing the blasting results at limestone quarry Hardovac near Doboj (Bosnia & Herzegovina) recorded in period 2012–2015. Analysis is conducted using the multiple linear regression (MLR) and artificial neural networks (ANN) for establishing the correlation between the peak particle velocity, vibration freque ...
... BACKGROUND: Refugia is considered to be critical for maintaining biodiversity; while discerning the type and pattern of refugia is pivotal for our understanding of evolutionary processes in the context of conservation. Interglacial and glacial refugia have been studied throughout subtropical China. However, studies on refugia along the oceanic–continental gradient have largely been ignored. We use ...

Abstract:
... There have been a variety of definitions of a “spice” type variable in physical oceanography. These variables have been used to measure water‐mass variations and to examine how the stability ratio varies vertically on a water column. Some authors have chosen to derive such an oceanographic variable, called potential spicity, so that its isolines are orthogonal to isolines of potential density on a ...

Abstract:
... The Taylor column, a typical hydrological structure around a seamount, can help to explain the high biomass and biodiversity around the seamount. However, it is difficult to observe a Taylor column in the field because it is easy to be destroyed by the change of ocean environment. Fortunately, a Taylor column around the C4 seamount in the Tropical Western Pacific Ocean was identified during our cr ...

Abstract:
... During the period of rapid urbanization, the urban fringe area is the area where urban expansion occurs first, and land use change is the most active. Studying its evolution laws and characteristics is of great significance to urban planning and urban expansion, and the primary task of fringe area research is the spatial recognition and boundary division of urban fringe area. The previous methods ...

Abstract:
... The results of the field radiometric survey of the mined monazite Vasil’evka placer in southern Yakutia are presented. It is shown that the natural background radioactivity of soils of the surveyed area mainly depends on the features of its geological structure and, to some extent, on landscape-geocryological conditions. The rate of equivalent dose of gamma radiation on the soil surface of the stu ...

Abstract:
... Ectotherms can become physiologically challenged when performing oxygen-demanding activities (e.g., flight) across differing environmental conditions, specifically temperature and oxygen levels. Achieving a balance between oxygen supply and demand can also depend on the cellular composition of organs, which either evolves or changes plastically in nature; however, this hypothesis has rarely been e ...

Abstract:
... Rice (Oryza sativa) is a short‐day (SD) plant originally having strong photoperiod sensitivity (PS), with SDs promoting and long days (LDs) suppressing flowering. Although the evolution of PS in rice has been extensively studied, there are few studies that combine the genetic effects and underlying mechanism of different PS gene combinations with variations in PS. We created a set of isogenic line ...

Abstract:
... An environmental risk assessment related to the genetically modified crops still needs to be studied. In the non-target organisms, rove beetles seem to be well-chosen arthropods for this purpose. Rove beetle abundance and species diversity were studied in the first large-scale Bt-maize experiment in the south part of Poland for over two years to determine the impact of Bt-maize in comparison to co ...

Abstract:
... The corn earworm/bollworm, Helicoverpa zea (Boddie), in the United States is targeted by transgenic corn and cotton expressing Bacillus thuringiensis (Bt) proteins. Previous studies have shown that resistance to Cry1A/Cry2A Bt corn has occurred in the field. In this study, we established 103 F2 isolines by mass-mating of H. zea populations collected during 2018 and 2019 in four southeastern U.S. s ...

Abstract:
... Numerous processes can cause upwelling, but the processes that cause upwelling along the east coast of Peninsular Malaysia (ECPM) are not well understood. Therefore, the dynamics of upwelling driving processes along the ECPM were investigated in this study. During the southwest monsoon, satellite-derived sea surface temperature (SST) and cruise surveys revealed the presence of upwelling signals, w ...
... Kernel weight (KW), together with kernel number per unit area, determines yield of cereal crops. Here, two barley recombinant inbred lines (RILs) populations with a shared parent were used to identify loci controlling KW. One is Baudin/AWCS276 (BA) for which a linkage map was available. Several large-effect QTL controlling KW were detected in this population. Another is Morex/AWCS276 (MA). A linka ...
