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 Levels 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 variables, 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 samples（0–30 cm） to generate spatially explicit estimates of SOC native forests in Argentina at a spatial resolution of approximately 200 m. We selected 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,

This report presents our experience with T therapy in a cohort of T-deficient men on active surveillance （AS） for Gleason 3 ＋ 3 and Gleason 3 ＋ 4 prostate cancer （PCa）. A retrospective chart review identified 28 men with T deficiency who underwent T therapy （T group） for at least 6 months while on AS for PCa. A comparison group of 96 men on AS for PCa with untreated T deficiency （no-T group） was identified at the same institution. The AS protocol followed a modified Epstein criteria and allowed inclusion of men with a single core of low-volume Gleason 3 ＋ 4 PCa. Mean age was 59.5 and 61.3 years, and mean follow-up was 38.9 and 42.4 months for the T and no-T groups, respectively. Of all 28 men in the T group, 3 （10.7%） men developed an increase in Gleason score while on AS. Of 22 men in the T group with Gleason 3 ＋ 3 disease, 7 （31.8%） men developed biopsy progression including 3 men （13.6%） who developed Gleason 3 ＋ 4 PCa. Of 6 men with Gleason 3 ＋ 4 disease at baseline, 2 （33.3%） men developed an increase in tumor volume, and none developed upgrading beyond Gleason 3 ＋ 4. All 96 men in the no-T group had Gleason 3 ＋ 3 disease at baseline and, 43 （44.7%） developed biopsy progression, including 9 men （9.38%） with upgrading to Gleason 7 （3 ＋ 4）. Biopsy progression rates were similar for both groups and historical controls. Biopsy progression in men on AS appears unaffected by T therapy over 3 years. Prospective placebo-controlled trials of T therapy in T-deficient men on AS should be considered given the symptomatic benefits experienced by treated men.
