Estimating body size in early primates: The case of Archicebus and Teilhardina
-
Obtaining accurate estimations of the body mass of fossil primates has always been a subject of interest in paleoanthropology because mass is an important determinant for so many other aspects of biology, ecology, and life history. This paper focuses on the issues involved in attempting to reconstruct the mass of two early Eocene haplorhine primates, Teilhardina and Archicebus, which pose particular problems due to their small size and temporal and phylogenetic distance from extant primates. In addition to a ranking of variables from more to less useful, the effect of using models of varying taxonomic and size compositions is examined. Phylogenetic correction is also applied to the primate database. Our results indicate that the choice of variable is more critical than the choice of model. The more reliable variables are the mediolateral breadth across the femoral condyles and the area of the calcaneocuboid facet of the calcaneus. These variables suggest a body mass of 39 g (range 33e46 g) for Archicebus and 48 g (range 44 e56 g) for Teilhardina. The width of the distal femur is found to be the most consistent estimator across models of various composition and techniques. The effect of phylogenetic correction is small but the choice of branch length assumption affects point estimates for the fossils. The majority of variables and models predict the body mass of Archicebus and Teilhardina to be in the range of the smaller extant mouse lemurs, as expected.

Estimating body size in early primates: the case of Archicebus and Teilhardina
-
Archicebus achilles and Teilhardina belgica are among the earliest Eocene primates so knowledge of their paleobiology is crucial to our understanding of early primate evolution. Since body mass is often a key to evaluating other important aspects of paleobiology determination of the likely body mass of these early primate taxa is a significant task for paleoprimatologists. These particular taxa pose several interesting problems for body mass estimation. First, they are at the far small end of body size distribution of living primates. Secondly, they are not nested within any family of living primates but lie at or near the base of the tarsiiform radiation. Thirdly, their nearest living relatives (tarsiers) are highly derived dentally, cranially, and postcranially. All of these raise the question of how to choose an appropriate reference group. In addition Archicebus, although represented by many skeletal elements, is a sample of one while Teilhardina is represented by more individuals but fewer different skeletal elements. Using samples of extant strepsirhines, tarsiers, and anthropoids to construct bivariate and multiple regression models we investigated the effects of choice of reference population (different size ranges and different phylogenetic groups) on estimates of body mass in these fossil taxa. We conclude that even the best statistical estimates have wide confidence intervals which need to be taken into account if body mass is used to predict other aspects of the fossil taxon’s behavior and ecology.

EuroGeoSurveys: from a non-profit association to ageological service for Europe
-
EuroGeoSurveys (EGS) is a not-for-profit organization representing 37 national geological surveysand some regional surveys; it has an overall workforce of several thousand experts. EGS members provide offi-cial, interoperable, homogeneous, reliable, INSPIRE (infrastructure for spatial information in the EuropeanCommunity)-compliant public data on the subsurface for the benefit of society in terms of circular economydevelopment, sustainable management of the subsurface resources, understanding and combatting climatechange and the development of infrastructures and mitigation of geology-related natural hazards. The EGSis committed to establishing a geological service for Europe based on three pillars: (1) joint research withimpact on EU policy level, which is being implemented through the GeoERA programme (Establishing theEuropean Geological Surveys Research Area to deliver a Geological Service for Europe); (2) harmonizingand sharing pan-European geological data, through the European Geological Data Infrastructure (EGDI);and (3) sharing knowledge, capacities and infrastructure, through the pan-African support to the EGS-Organi-zation of African Geological Surveys (OAGS) Partnership (PanAfGeo project). The EGS will continue to sup-port the EU in its transition to a low-carbon, climate-neutral, resource-efficient, socially and environmentallyresilient economy, in full compliance with the United Nations 2030 Agenda and the 17 Sustainable Develop-ment Goals.

EuroGOOS roadmap for operational coastal downstream services
-
The EuroGOOS Coastal working group examines the entire coastal value chain from coastal observations to services for coastal users. The main objective of the working group is to review the status quo, identify gaps and future steps needed to secure and improve the sustainability of the European coastal service provision. Within this framework, our white paper defines a EuroGOOS roadmap for sustained “community coastal downstream service” provision, provided by a broad EuroGOOS community with focus on the national and local scale services. After defining the coastal services in this context, we describe the main components of coastal service provision and explore community benefits and requirements through sectoral examples (aquaculture, coastal tourism, renewable energy, port, cross-sectoral) together with the main challenges and barriers to user uptake. Technology integration challenges are outlined with respect to multiparameter observations, multi-platform observations, the land-coast-ocean continuum, and multidisciplinary data integration. Finally, the technological, financial, and institutional sustainability of coastal observing and coastal service provision are discussed. The paper gives special attention to the delineation of upstream and downstream services, public-private partnerships and the important role of Copernicus in better covering the coastal zone. Therefore, our white paper is a policy and practice review providing a comprehensive overview, in-depth discussion and actionable recommendations (according to key short-term or medium-term priorities) on the envisaged elements of a roadmap for sustained coastal service provision. EuroGOOS, as an entity that unites European national operational oceanography centres, research institutes and scientists across various domains within the broader field of operational oceanography, offers to be the engine and intermediary for the knowledge transfer and communication of experiences, best practices and information, not only amongst its members, but also amongst the different (research) infrastructures, institutes and agencies that have interests in coastal oceanography in Europe
