Data from: Movement diversity and partial sympatry of coastal and Northeast Arctic cod ecotypes at high latitudes
<p>Movement diversity within species represent an important, but often neglected, component of biodiversity that affects ecological and genetic interactions, as well as the productivity of exploited systems. By combining individual tracking data from acoustic telemetry with novel genetic analyses, we describe the movement diversity of two Atlantic cod <em>Gadus morhua</em> ecotypes in two high-latitude fjord systems: the highly migratory Northeast Arctic cod (NEA cod) that supports the largest cod fishery in the world, and the more sedentary Norwegian coastal cod, which is currently in a depleted state. As predicted, coastal cod displayed a higher level of fjord residency than NEA cod. Of the cod tagged during the spawning season, NEA cod left the fjords permanently to a greater extent and earlier compared to coastal cod, which to a greater extent remained resident and left the fjords temporarily. Despite this overall pattern, horizontal movements atypical for the ecotypes were common with some NEA cod remaining within the fjords year-round and some coastal cod displaying a low fjord fidelity. Fjord residency and exit timing also differed with spawning status and body size, with spawning cod and large individuals tagged during the feeding season more prone to leave the fjords and earlier than non-spawning and smaller individuals. While our results confirm a lower coastal dependency for NEA cod, they highlight a movement diversity within each ecotype and sympatric residency between ecotypes, previously undetected by population-level monitoring. This new knowledge is relevant for the management, which should base their fisheries advice for these interacting ecotypes on their habitat use and seasonal movements.</p>
Heterogeneous microgeographic genetic structure of the common cockle (Cerastoderma edule) in the Northeast Atlantic Ocean: biogeographic barriers and environmental factors
<p>Knowledge of genetic structure at the finest level is essential for conservation of genetic resources. Despite no visible barriers limiting gene flow, significant genetic structure has been shown in marine species. The common cockle (<em>Cerastoderma</em> <em>edule</em>) is a bivalve of great commercial and ecological value inhabiting the Northeast Atlantic Ocean. Previous population genomics studies demonstrated significant structure both across the Northeast Atlantic, but also within small geographic areas, highlighting the need to investigate fine-scale structuring. Here, we analysed two geographic areas that could represent opposite models of structure for the species: 1) the SW British Isles region, highly fragmented due to biogeographic barriers, and 2) Galicia (NW Spain), a putative homogeneous region. 9,250 SNPs genotyped by 2b-RAD on 599 individuals from 22 natural beds were used for the analysis. The entire SNP dataset mostly confirmed previous observations related to genetic diversity and differentiation, however, neutral and divergent SNP outlier datasets enabled disentangling physical barriers from abiotic environmental factors structuring both regions. While Galicia showed a homogeneous structure, the SW British Isles region was split into four reliable genetic regions related to oceanographic features and abiotic factors, such as sea surface salinity and temperature. The information gathered supports specific management policies of cockle resources in SW British and Galician regions also considering their particular socio-economic characteristics; further, these new data will be added to those recently reported in the Northeast Atlantic to define sustainable management actions across the whole distribution range of the species.</p>
Drained lakes in Northeast Siberian Coastal Tundra between 2000–2020
<p>Thermokarst lakes in permafrost regions are highly dynamic due to drainage events triggered by climate warming. This study focused on mapping lake drainage events across the Northeast Siberian Coastal Tundra from 2000–2020 and identifying influential factors. An object-based lake analysis method was developed to detect 238 drained lakes using a well-established surface water dynamics product.</p> <p> </p> <p>Citation</p> <p>If you find this work helpful, please consider citing the paper: [Link waiting to be generated]</p>

Fish species classification, trophic guilds and geographical distribution of northeast China
<p>Muling River, surrounded by cultivated land of Heilongjiang Province in the northeast of China, experienced sand-digging activities for a long time, and its riverbed has been seriously damaged. However, the knowledge about the impact of this disturbance on the status of fish community structure and diversity was little studied in this river. In this study, environmental factors and fish assembles from Muling River were investigated in spring, summer and autumn of 2015 and 2017, respectively. During the investigation period, 46 species of five orders and 12 families of fish were classified into seven trophic guilds. Our results demonstrated that the fish species diversity indices and variation trends of the Shannon-Wiener diversity index, Pielou evenness index and Margalef richness index were consistent. RDA analysis showed that water depth was significantly correlated with zooplankton feeding habits, and transparency correlated with aquatic plant feeding. This study supports the need for trophic guilds taxonomic studies of freshwater fishes to underpin management in areas subject to significant environmental change.</p>
A weak subducting slab at intermediate depths below northeast Japan
<p>Knowledge of the state of stress in subducting slabs is essential for understanding their mechanical behavior and the physical processes that generate earthquakes. Here we develop a novel framework that uses a high-resolution focal mechanism catalog to determine, for the first time, the full deviatoric stress tensor within the subducting slab at intermediate depths. We show that by combining the static stress calculated from coseismic slip distributions with the stress orientations before and after the mainshock, that deviatoric stress within the slab at intermediate depths must be very low ( ∼ 1 MPa). These results preclude earthquake source mechanisms that require large background driving stresses, favoring a mechanically weak subducting slab, thus providing quantitative constraints on the physical processes that generate intermediate-depth earthquakes.</p>
Curcuma kakchingense (Zingiberaceae), a new species from northeast India
<p><em>Curcuma kakchingense</em> Bidyaleima, Kishor & Sharma, a new species of <em>Curcuma</em> subg. <em>Curcuma</em> (Zingiberaceae) from Manipur, Northeast India is described and illustrated. The species has close resemblance to<em> C. phrayawan</em> and <em>C. longa</em> but is distinguished by having lemon-yellow-coloured rhizomes with a very bitter taste, glabrous dark reddish-brown bladeless sheaths, reddish-brown petiole fading towards the edges, densely pubescent coma and upper fertile bracts on both surfaces with mucronate tip, broadly ovate bracteole, elongated and revolute apex of the middle lobe of the labellum and stigma protruding through the anther lobes. The chromosome number is established as 2n = 3x = 63.</p>
