A description of one new, and redescription of one known, species of the subfamily Adoncholaiminae (Nematoda: Oncholaimidae) from Peter the Great Bay (Sea of Japan) are provided. Adoncholaimus ussuriensis sp. n. is characterised by relatively large body size (L = 4.3-5.8 mm in male, 4.4-6.2 mm in female), a pair of terminal pores of the Demanian system opening dorsally at 147-189 μm (2.3-3.0 abd) anterior to the anus, excretory pore located posterior to buccal cavity region, absence of a ventral swelling on tail, long spicules (190-230 μm), presence of a gubernaculum (32-40 μm), presence of a complicated sensory field in the male with a complex supplementary organ and two sets of pilose filaments (5-10 μm long) on the posterior cloacal lobe and four rows of subventral and subdorsal postcloacal sensilla. We provide a redescription of Admirandus multicavus illustrated by light and scanning electron micrographs and propose Adoncholaimus chinensis as a junior synonym of Admirandus multicavus. The diagnoses of both genera are emended. Partial sequences of the mitochondrial gene cytochrome oxidase c subunit I (COI) and D2-D3 region of the 28S rDNA for both species were obtained. A dichotomous key to Adoncholaimus species is provided.

Морское побережье является одной из самых выраженных естественных географических границ, которая одновременно разделяет и связывает географические структуры суши морей или океанов. В основе формирования типов природопользования в прибрежных зонах, как и на других типах географического пространства, лежит природноресурсный потенциал. Природноресурсный потенциал и типы природопользования как явления пространственнодифференцированные должны быть рассмотрены, прежде всего, в рамках классических географических подходов и оценок, таких как районирование территории и акватории. При этом пространственные сочетания наземных и морских природных, природноресурсных компонентов рассматриваются как важнейшие предпосылки инфраструктурного и хозяйственного развития прибрежных регионов. Необходимым этапом природноресурсного районирования является выявление границ, при пересечении которых существенно меняются природные ресурсы и условия. Данная работа выполнена на примере рассмотрения минеральных ресурсов прибрежных муниципальных образований и является частью исследования природноресурсных сочетаний зоны сушаокеан Дальнего Востока России в рамках изучения пространственной дифференциации факторов, условий и ограничений формирования и развития структур природопользования в прибрежной зоне Тихоокеанской России с учетом воздействия экстремальных природных процессов и явлений. Дана сравнительная характеристика месторождений минерального сырья российской части побережья Японского моря. Определена их видовая и географическая структура. На основе того, что месторождения минерального сырья сгруппированы в 8 основных ресурсных групп ввыполнено районирование российской части побережья Японского моря по сочетанию основных видов минеральных ресурсов. Выделены типы муниципальных образований по сочетанию минеральных ресурсов и показаны особенности каждого из них. Выделены шесть районов по сочетанию минеральных ресурсов. В связи с необходимостью учета географической особенности в сочетании со спецификой минеральных ресурсов, северной и южной частям территории одного типа районов присвоены свои собственные названия. По результатам исследования была построена карта. The seacoast is one of the most pronounced natural geographical boundaries, which divides and connects simultaneously the geographical structures of the land, seas or oceans. The formation of the types of nature management in coastal zones, as well as on other types of geographical space, is based on the natural resource potential. Being spatially differentiated phenomena, the natural resource potential and the types of environmental management should be considered, first of all, within the framework of classical geographical approaches and assessments, such as zoning of the territory and water areas. In this case, spatial combinations of the land and sea natural, naturalresource components are considered as the most important prerequisites for the infrastructure and economic development of coastal regions. Identification of borders, at the intersection of which the natural resources and conditions change significantly, is a necessary stage of natural resource zoning. This work is carried out by example of consideration of mineral resources of coastal municipal unions and appears to be a part of studies of naturalresource combinations of the landocean zone of the Russian Far East in the framework of studies of spatial differentiation of factors, conditions and restrictions of formation and development of structures of nature management in the coastal zone of Pacific Russia, taking into account the influence of extreme natural processes and phenomena. The comparative characteristic of mineral deposits of the Russian part of the coast of the Sea of Japan is given. Their species and a geographical structure are determined. Based on the fact that the mineral deposits are grouped into eight main resource groups, zoning of the Russian part of the coast of the Sea of Japan by a combination of the main types of mineral resources is performed. The types of municipalities are allocated by a combination of mineral resources and their features are shown. Six areas are singled out by a combination of mineral resources. Due to the need to take into account the geographical features in combination with the specifics of mineral resources, the northern and southern parts of the territory of one type of areas have obtained their own names. According to the results of the studies, the map has been compiled.

AbstractThis study examines long-term ocean pH data to evaluate ocean acidification (OA) trends at two coastal research institutions located on the Sea of Japan and the Pacific Ocean. These laboratories are located away from the influences of large rivers and major industrial activity. Measurements were performed daily for the past 30 years (1980s–2010s). The average annual ocean pH for both sites showed generally negative trends. These trends were – 0.0032 and – 0.0068 year–1 (p < 0.001) at the Sea of Japan and Pacific Ocean sites, respectively. The trends were superimposed onto approximately 10-year oscillations, which appear to synchronize with the ocean current periodicity. At the Sea of Japan site, the ocean pH in the summer was higher, and the rate of OA was higher than during other seasons. Our results suggest that seasonality and ocean currents influence OA in the coastal areas of open oceans and can affect the coastal regions of marginal seas.
