Preserving microbial diversity has become a strategic undertaking. Thus, ex situ microalgal culture conservation results in strategic and functional resource in both biodiversity protection and application domains. Cryopreservation of microalgae has been practiced since the 1960s and is now considered the optimal preservation strategy. Furthermore, the overall monitoring during growth of cultures after freezing/thawing protocols was hardly investigated and there is poor evaluation related to preserve especially the photosystem apparatus. The present study focuses on Stichococcus bacillaris as case study for short-term cryopreservation at −80 °C storage. Various freezing pretreatments using cryoprotective agents, and two thawing methods were compared introducing a novel variable to evaluate viability recovery and assessing growth kinetics of cultures immediately after thawing and after a series batch cultivation. Photosynthetic rate and pigments assessment were proposed to evaluate hidden metabolic cell damage. Results underline cryoprotective agents can increase the kinetic recovery of preserved cells in terms of reduction of lag phase during batch cultivation tests: the use of dimethyl sulfoxide and glycerol granted a growth comparable to unpreserved cells when sudden thawing occurs after 24 hours of storage, but recovery after preservation is less sensitive to cryoprotective agents when gradual thawing and 1 month of storage is considered. However, cells are always able to restore their physiological pathways even without agents, so their kinetic effect has been proved and quantified. Interestingly, both the photosynthetic efficiency and the ratio between total chlorophyll and carotenoids are comparable (0.75 Fv/Fm, 2.2 ± 0.25 g/g) to unpreserved cells and they are unsensitive to chosen agents, but the ratio between chlorophyll a and chlorophyll b was clearly altered (up to 10 times), suggesting that photoactive pigments relative proportions

Tourmaline is a common borosilicate mineral in granite and pegmatite， and it is also an important carrier to record the physicochemical evolution information of magmas. However， the genetic relationship between pegmatite-type rare metal mineralization potential and tourmaline-bearing pegmatites is not clear， and the tourmaline geochemical indication of the mineralization type of rare metals needs to be supplemented. In the middle Altun region， extensive tourmaline-bearing pegmatite dykes are prevalent within and surrounding the Tugeman complex. In this paper， the petrology and geochemical characteristics of tourmaline within the pegmatite of the Tugeman Be-Li deposit have been comprehensively analyzed. The research delves into the genetic evolution and metallogenic potential of the pegmatite， emphasizing the indicative role of tourmaline geochemistry in discerning mineralization types in the Tugeman Be-Li deposit. Major and trace element analysis of tourmaline reveals varying contents of FeO （9.37 wt.%–17.10 wt.%）， Al2O3（28.64 wt.%–35.22% wt.%）， and MgO （0.13 wt.%–2.47 wt.%） in the Tugeman Be–Li pegmatite. Li， Zn， and Sn contents range from 204 ppm to 1 590 ppm， 1 143 ppm to 4 089 ppm， and 74 ppm to 396 ppm， respectively. The tourmaline analyzed in this study is magmatic origin and belongs to schorl series， exhibits substitution relationships， including (Na， Fe2+)(X□， Al)-1， (Fe2+， Fe3+)（Mg， Al）-1， (Al，X□)(R2+， Na)-1，（Na， Mg）(X□， Al)-1andX□NaR2+-1. The trace element data of tourmaline show that lithium has four enrichment stages in different mineral crystallization phases. Notably， the tendency of tourmaline in the Tugeman Be-Li pegmatite to evolve towards elbaite implies a magmatic evolution sequence from low to high， transitioning through microcline-albite pegmatite， muscovite-microcline-albite pegmatite， albite pegmatite， and microcline pegmatite. Furthermore， we also propose that the Sc content in schorl can serve as an indicator of pegmatite mineralization typ

The evolution of territorial space is intrinsically linked to economic growth, societal welfare, and ecological preservation. In the context of escalating spatial conflicts and stringent resource limitations, resource efficiency has emerged as a fundamental pillar for the scientific optimization of territorial space layout. Drawing upon resource efficiency metrics from cities nationwide, this study constructs scenarios for territorial space development and conservation, assesses developmental capacity under varying preferences, and subsequently delineates strategic blueprints using an integrated “point-axis-area” approach. The findings reveal the following:(1) Resource efficiency in China has witnessed a consistent uptick, yet remains modest overall, with marked regional disparities.(2) Throughout the investigation period, developmental capacity has seen progressive enhancement, with a pronounced capacity in scenarios favoring development, radiating axially from urban conglomerates.(3) The layout of pivotal points and developmental axes has transitioned from a “tri-pillar” to a diamond configuration, with the coastal corridor, Harbin-Beijing-Guangzhou corridor, and the corridor along the Yangtze River standing out.(4) Strategic points progressively converge along key axes, whereas dominant regions exhibit clear differentiation on either side of the Hu Huanyong Line. By integrating elements of the territorial spatial structure,this paper proposes blueprints for “five horizontal and three vertical zones with eight cores and three areas,” “four horizontal and three vertical zones with six cores and three areas,”and “three horizontal and four vertical zones with five cores and three areas,” corresponding to scenarios of prioritizing development, status quo maintenance, and prioritizing conservation, respectively. The outcomes of this research offer a technical foundation and theoretical guidance for the pursuit of high-quality territorial space development and a vision
