More than 60 million specimens are housed in geological and biological collections in numerous museums and botanical gardens located all over Switzerland. They are of national and international origin. Taken together they form an entity with a high scientific value and international recognition for their contribution to scientific research. Due to the federalistic organisation of Switzerland, natural history collections are located and curated in numerous institutions. So far, no common strategy for digitisation, documentation and long-term data archiving has been developed. This shortcoming has been widely identified by concerned parties. Under the lead of the Swiss Academy of Sciences, several organisations have assembled information about Swiss natural history collections. They identified measures to be taken to promote the scientific and educational potential of natural history collections in Switzerland (Beer et al. 2019). With a national initiative, the Swiss Natural History Collections Network (SwissCollNet) aims to unite Swiss natural history collections under a common vision and with a common strategy. The goal is to promote the collections themselves and to harness the scientific and educational potential of these collections for research and training. SwissCollNet consists of representatives of research, teaching, museums and botanical gardens, the data centers for information on the national fauna and flora, the Swiss Systematics Society and the Swiss node of GBIF, the Global Biodiversity Information Facility. The initiative aims to foster research on natural history collections. It will provide a single decentralised data infrastructure framework for Swiss research related to natural history. It will help to harmonise nationwide collection data management, digitisation and long-term data archiving. It will facilitate identification of specimens and revision of taxonomic groups. New research techniques, fast-evolving computer technologies and internet connectivity, create new opportunities for deciphering and using the wealth of information housed in Swiss and international collections. The development of an agreed strategy and research priorities on a national scale will allow fluent, fluid and permanent collaboration across all Swiss natural history collections by promoting interoperability and unified access to collections as well as creating opportunities for scientific collaboration and innovation. This national approach will create an internationally compatible research data infrastructure, while respecting and integrating regional and decentralized conditions and requirements. Thus, it will maximize the impact for science, policy and society.

This paper focuses on the digital documentation techniques employed in the recording of a number of Saite-Persian sarcophagus-tombs in the necropolis of Saqqara (Egypt). In this paper, we discus pros and cons of different three-dimensional technologies for the documentation of a vast site as well as the process of ongoing excavation. We then delve into a discussion of the results and benefits of the employed techniques, particularly understanding the complex spatial relationships of archaeological features both aboveground and underground. Furthermore, we explain how we derive precise scaled and ortho-rectified images of all inscribed walls and objects from the recorded 3D-information in order to produce digital facsimiles. The 3D approach gives us the opportunity to create an exact digital copy of the site, and to record all stages of the excavation. The produced 3D models can be used in various virtual environments in order to give researchers and the general public the possibility to visit and to examine the site from a distance. Also, it is important to note that this paper presents a sustainable long-term data-archiving strategy, since saving the digitally-born data for future generations is an integral part of our Saqqara Saite Tombs Project.

This study presents a hydrogeochemical analysis of spring responses (2013-2017) in the tropical mountainous region of the Central Valley of Costa Rica. The isotopic distribution of δ18O and δ2H in rainfall resulted in a highly significant meteoric water line: δ2H = 7.93×δ18O + 10.37 (r2=0.97). Rainfall isotope composition exhibited a strong dependent seasonality. The isotopic variation (δ18O) of two springs within the Barva aquifer was simulated using the FlowPC program to determine mean transit times (MTTs). Exponential-piston and dispersion distribution functions provided the best-fit to the observed isotopic composition at Flores and Sacramento springs, respectively. MTTs corresponded to 1.23±0.03 (Sacramento) and 1.42±0.04 (Flores) years. The greater MTT was represented by a homogeneous geochemical composition at Flores, whereas the smaller MTT at Sacramento is reflected in a more variable geochemical response. The results may be used to enhance modelling efforts in central Costa Rica, whereby scarcity of long-term data limits water resources management plans.

The long-term data from morphometric studies of Artemia males from bisexual and parthenogenetic populations from hyperhaline reservoirs of the Altai region (Bolshoe Yarovoe Lake, Maloe Shklo Lake, and the Tanatar Lakes system) is analyzed in this paper. The description of signs of sexual dimorphism and sexual structure in different populations is given. The influence of brine salinity and hydrogen index on morphometric parameters of males was analyzed. There are differences in the sexual structure of the Artemia population: in the lakes Maloe Shklo and the thanatar system, the populations are bisexual (the share of males is 28.5 — 75.0 %), in the lake Bolshoe yarovoe — parthenogenetic (the share of males on average does not exceed 3 %). At the same time, sexual dimorphism is typical for both types of populations: females are larger than males, males have a larger head (the distance between the eyes is greater by 15.5 %, the diameter of the eye is 26.1 %, the length of the antenna is 22.3 %) and a larger number of bristles (36.1 %). The greatest variability is observed in the parameters of the Furka structure associated with the salinity of water by feedback and the pH — line indicator. Significant differences between the samples of males were revealed. The largest number of significant differences in morphometric indicators was found between samples of males from bisexual populations (lake thanatar and lake Maloe Shklo), the smallest — between males from the parthenogenetic population of lake Bolshoe yarovoe and males from lake Maloe Shklo.
