    Geodynamic conditions of rifting on the Earth surface: problems of studying by T. Yu. Tveritinova

    Published 2017-03-01
    “…Most of the studied rift systems are associated with shear zones that contain extension faults with normal fault components, as well as strike-slip and compression structures. The regular structural pattern on the Earth surface and its relation to the distribution of the mantle density variations reflect the deformation of the Earth as a triaxial rotating ellipsoid.…”

    The third dimension of alpine plant leaf traits is related to cold-tolerance by Yuan Wang, Ji Suonan, Kun Liu, Yanni Gao, Sihao Zhu, Qian Liu, Ning Zhao

    Published 2025-01-01
    “…Furthermore, a cold resistance experiment was conducted at one of these sites to estimate the lethal temperature causing 50% frost damage (LT50) of 11 alpine species. The majority of variations in 12 leaf traits of alpine plants were captured by three trait axes, in which leaf carbon (LCC) and NSC (including leaf starch; LSC and leaf soluble sugars; LSS) were clustered in a new dimension (PC3) beyond leaf size and structure, and resource economics. …”

    Genomic analysis of NE Atlantic sardine (Sardina pilchardus) reveals reduced variation in a recently established North Sea population and directs reconsideration of management unit... by Niall J. McKeown, Fabio Campanella, Joana F. Silva, Beatriz A. Roel, Amy J. E. Healey, Paul W. Shaw, Jeroen van derKooij

    Published 2024-08-01
    “…The North Sea sample exhibited markedly lower mtDNA and nuclear variation than other samples. As sardine have only recently invaded the North Sea such reduced genetic variation is compatible with predictions for peripheral leading‐edge populations but contrasts with patterns for other small pelagic species and emphasises the need to consider species‐specific genetic structure in ecosystem‐based management. …”
