Background The nationally determined contribution(NDC) presented by Argentina within the framework of the Paris Agreement is aligned with the decisions made in the context of the United Nations Framework Conven-tion on Climate Change(UNFCCC) on the reduction of emissions derived from deforestation and forest degradation, as well as forest carbon conservation(REDD+). In addition, climate change constitutes one of the greatest threats to forest biodiversity and ecosystem services. However, the soil organic carbon(SOC) stocks of native forests have not been incorporated into the Forest Reference Emission le.els calculations and for conservation planning under cli-mate variability due to a lack of information. The objectives of this study were:(i) to model SOC stocks to 30 cm of native forests at a national scale.using climatic, topographic and vegetation as predictor variable., and(ii) to relate SOC stocks with spatial–temporal remotely sensed indices to determine biodiversity conservation concerns due to threats from high inter-annual climate *** We used 1040 forest soil sample.(0–30 cm) to generate spatially explicit estimates of SOC native forests in Argentina at a spatial resolution of approximately 200 m. We sele.ted 52 potential predictive environmental covari-ates, which represent key factors for the spatial distribution of SOC. All covariate maps were uploaded to the Google.Earth Engine cloud-based computing platform for subsequent modelling. To determine the biodiversity threats from high inter-annual climate variability, we employed the spatial–temporal satellite-derived indices based on Enhanced Vegetation Index(EVI) and land surface temperature(LST) images from Landsat *** SOC model(0–30 cm depth) prediction accounted for 69% of the variation of this soil property across the whole.native forest coverage in Argentina. Total mean SOC stock reached 2.81 Pg C(2.71–2.84 Pg C with a probability of 90%) for a total area of 460,790 km2,

Aside from polo and Aurora, a third but le.s studied kinase family involved in mitosis regulation is the never in mitosis-gene A(NIMA)-related kinases(Neks). The founding member of this family is the sole.member NIMA of Aspergillus nidulans, which is crucial for the initiation of mitosis in that organism. All 11 human Neks have been functionally assigned to one of the three core functions established for this family in mammals:(1) centriole./mitosis;(2) primary ciliary function/ciliopathies; and(3) DNA damage response(DDR). Recent findings, especially on Nek 1 and 8, showed however, that several Neks participate in paralle. in at le.st two of these contexts: primary ciliary function and DDR. In the core section of this in-depth review, we report the current detaile. functional knowle.ge on each of the 11 Neks. In the discussion, we return to the cross-connections among Neks and point out how our and other groups' functional and interactomics studies reveale. that most Neks interact with protein partners associated with two if not all three of the functional contexts. We then raise the hypothesis that Neks may be the connecting regulatory ele.ents that allow the cell to fine tune and synchronize the cellular events associated with these three core functions. The new and exciting findings on the Nek family open new perspectives and should allow the Neks to finally claim the attention they deserve in the field of kinases and cell cycle.biology.
