“…This may correspond to the range of scales at which nutrias perceive habitats that are functionally connected in the middle and downstream regions of the Nakdong River Basin, which might be associated with species traits, such as movement behavior and perceptual range, as well as environmental conditions. Despite their philopatric behavior, nutrias are known to travel tens of kilometers when resources are limited [25,79]. However, due to…”

The nutria (Myocastor coypus), also known as the coypu, is a semi-aquatic, invasive rodent native to South America that causes damage to natural riverine and wetland habitats in many parts of the world, including South Korea. Understanding habitat use, connectivity, and gene flow of nutria populations is critical for the sound management of local and regional ecosystems. Here, we assessed habitat suitability and connectivity in relation to the genetic structure of nutria populations in the Nakdong River Basin of South Korea. A total of 321 nutria occurrence sites and seven environmental variables were used to perform ensemble habitat suitability modeling using five species distribution models (SDMs), including boosted regression trees, maximum entropy model, random forest, generalized linear model, and multivariate adaptive regression splines. Using graph and circuit theory approaches, we assessed the population gene flow and current flow betweenness centrality (CFBC) of suitable habitats derived from the ensemble SDM. All SDMs performed well with a range of test AUC values from 0.962 to 0.970 (mean = 0.966) with true skill statistic values over 0.8. The minimum temperature of the coldest month, mean temperature of the warmest quarter, precipitation of the driest quarter, and distance from water bodies were important predictors in nutria habitat modeling. Nutria population gene flow was significantly correlated with the least-cost path distance on a cost resistance surface based on ensemble habitat suitability modeling and roads (Mantel’s r = 0.60, p < 0.05). Finally, the CFBC positively correlated with the genetic diversity of nutria populations was used to identify priority control areas. Habitat suitability and connectivity modeling not only revealed environmental conditions and areas that support the survival and spread of nutrias, but also improved our understanding of the animals’ genetic population structure, thereby indicating priority areas to target for eradication.

“…For a catalyst, the use of H 3PO4 in a mixture of H2SO4 [118] or sulfonates [119,120] was proposed. Reference [121] proposed the use of the RSO3H-2CH3COOH system to polymerize the unsaturated hydrocarbons that did not react at the first, thermal stage of polymerization of the liquid pyrolysis products. Each method had a number of specific problems that did not allow for the study to continue beyond the laboratory or experimental setting.…”

Processes for producing lower olefins are critically examined. It is noted that pyrolysis of various types of hydrocarbon isstill the main process of obtaining ethylene and propylene, and is accompanied by the formation of considerable amounts of by-products,such as liquid pyrolysis products. We present an analysis of domestic and foreign scientific, technical, and patent information pertaining to therational use of petrochemical production by-products, aimed at obtaining hydrocarbon (petroleum) resins. We consider the raw materialsinvolved in obtaining the resins, and generalize data on existing methods of obtaining resins using thermal, initiated, and ion (catalyst)polymerization.
