Climate model and proxy input data for PaleoDA South America reconstruction
<p>This repository contains input data needed to run the paleoclimate reconstruction code for "A continental reconstruction of hydroclimatic variability in South America during the past 2000 years", submitted to Climate of the Past in February 2024 [https://egusphere.copernicus.org/preprints/2024/egusphere-2024-545/]. The Github repository is located here: https://github.com/mchoblet/paleoda_sa/tree/main</p> <p><strong>Structure:</strong></p> <p>model_data: One File for each Model (GISS, CCSM (isoGSM), CESM, ECHAM5, iHADCM3) and variable (prec,tsurf,d18O, SPEI). Monthly resolution.</p> <p>proxy_data: One File for each proxy record type (Trees and corals contain a separate file for annual and djf linear regression parameters, the proxy data as such is the same). The data has yearly resolution, and thus also contains NaNs for when a year is not covered by a proxy. Note, that these time series are resampled to a regular resolution in the multi-time scale PaleoDA code.</p> <p><strong>Climate Model Data:</strong></p> <p>The original data can be found in https://zenodo.org/records/6610684.

Fig. 2 in The systematics of Late Jurassic tyrannosauroid theropods from Europe and North America
Fig. 2. The phylogenetic relationships of tyrannosauroids, based on a revised analysis of the Brusatte et al. (2010) dataset. Details of the analysis are described in the text and the dataset is presented in SOM. The cladogram shown here is the single most parsimonious tree recovered by the analysis, with the wildcard taxon Aviatyrannis excluded (570 steps, CI = 0.640, RI = 0.835). Numbers next to nodes denote bootstrap percentages (based on 1000 replicates) and Bremer support. Note that Stokesosaurus clevelandi and "S." langhami (here referred to by its new genus name, Juratyrant) are not found as sister taxa, and therefore a monophyletic Stokesosaurus is not recovered. When Aviatyrannis is included in the analysis, the strict consensus of nine most parsimonious trees (not figured) shows identical and fully resolved relationships among Xiongguanlong and all more derived taxa. However, Stokesosaurus clevelandi, "S." langhami, and Eotyrannus, form a polytomy. This clade, in turn, is part of a large basal polytomy that also includes the Xiongguanlong + more derived clade, Dilong, Aviatyrannis, Guanlong, Kileskus, Proceratosaurus, and Sinotyrannus. On the figured cladogram, the following unambiguous synapomorphies support major clades, with character numbering following that in the character list of Brusatte et al. (2010) and SOM: all tyrannosauroids more derived than Dilong (33, 41, 49, 80, 180, 181, 196, 198, 221, 239, 241, 244, 257, 274, 281, 289, 290); the clade of S. clevelandi, Juratyrant, and Eotyrannus (258, 310, 311, 313); the clade of Juratyrant and Eotyrannus (no unambiguous synapomorphies).

Production costs and their effect on the profitability of the SMES in Latin America
<p><span>The micro, small and medium-sized enterprises (SMEs) play a pivotal role in the Latin America economy, creating jobs, boosting local economic activity and contribute to the socio-economic development of the region. The purpose is to reflect on the current costs management prices, the common challenges faced by SMEs in the region, and effective strategies to improve the profitability and sustainability of these companies.</span></p>
