The article analyzes the development of the brotherhoods of the Indian town of Suratá before and after the Bourbon reforms of the 18th century. Through the books of brotherhoods of Santo Ecce Homo and of the Blessed Sacrament and various primary sources of the Indian people of Suratá, the process of transferring the indigenous population from their...
This study shows the characterization of krill (Euphausia superba) aggregations identified in the Bransfield Strait and around of Elephant Island. Data were collected using a multifrequency SIMRAD EK80 echosounder during three austral summers: 2018, 2019 and 2020. For detection of krill aggregations, two frequencies (38 and 120 kHz) and an automate...

AbstractData on the spatial distribution of the Walleye Pollock, Theragra chalcogramma, and the conditions of the habitat off the southern Kuril Islands in the spawning season of 2015 and the feeding season of 2016 are provided in this report. In the spring, most walleye pollock are distributed more evenly over the shelf and continental slope to a ...

AbstractIt was revealed that the southern border of the range of spectacled sculpin Triglops scepticus runs in the region of 37°23′ N. It has been confirmed that the southern border of the range of Jordan’s sculpin T. jordani is located in the South Korean waters; of ribbed sculpin T. pingelii range, in the North Korean waters. In the Russian water...

Methane clathrates are widespread on the ocean floor of the Earth. A better understanding of methane clathrate formation has important implications for natural-gas exploitation, storage, and transportation. A key step toward understanding clathrate formation is hydrate nucleation, which has been suggested to involve multiple evolution pathways. Her...

AbstractAnalysis of zooplankton collected on five cruises (2007–2016) in the Kara and Laptev seas has revealed considerable heterogeneity in the spatial distribution of the biomass of the pteropod Limacina helicina, one of the important components of the Arctic zooplankton. The biomass and abundance of mollusks in 2014–2016 were significantly lower...

Abstract—In Russian waters of the Sea of Japan, the threaded sculpin Gymnocanthus pistilliger occurs at depths of 5 to 217 m and water temperature in the near bottom layer from –1.4 to +18.7°С in the spring–autumn season. In spring, it migrates from the outer border of the shelf towards its heated middle and upper parts where it forms feeding aggre...
Structures are present in almost everything around us. In most of the systems that we interact with, or the way we interact with them, some emergent structure can often be observed. A simple sentence is a sequence of words. A small classroom of interacting students can be depicted as a network with each student defining a node of it. The emergent s...

How sociality evolves and is maintained remains a key question in evolutionary biology. Most studies to date have focused on insects, birds, and mammals but data from a wider range of taxonomic groups are essential to identify general patterns and processes. The extent of social behaviour among squamate reptiles is under-appreciated, yet they are a...

Most seabirds are very noisy at their breeding colonies, when aggregated in high densities. Calls are used for individual recognition and also emitted during agonistic interactions. When at sea, many seabirds aggregate over patchily distributed resources and may benefit from foraging in groups. Because these aggregations are so common, it raises th...
