Article Reference Do private coffee standards ‘walk the talk’ in improving socio-economic and environmental sustainability?
Private sustainability standards cover an increasingly large production area and involve an increasing number of farmers worldwide. They raise expectations among consumers about the economic, ethical and environmental implications of food production and trade; and attract donor funding to certification schemes. The sustainability impact of standards remains unclear as research focuses on either economic or environmental implications. We analyze both the socio-economic and environmental impacts of coffee standards in Uganda and show that these are not in line with expectations created towards consumers. We find that standards improve either productivity and farm incomes or biodiversity and carbon storage but fail to eliminate trade-offs between socioeconomic and environmental outcomes, even when combined in multiple certification. Our analysis is based on a unique combination of economic survey data and ecological field inventory data from a sample of certified and noncertified coffee farms. Our findings are relevant for farmers, food companies, policy-makers, donors and consumers. They imply that combining different standards in multiple certification is counterproductive; that the design of standards could improve to mitigate observed trade-offs between economic and environmental outcomes; and that this requires increased productivity within ecological boundaries, rather than a price premium and added control mechanisms through multiple certification

Inproceedings Reference Dormaal lizards in Belgium – a rare window into the earliest Eocene ‘greenhouse world’
During the Eocene, world climate experienced rapid and intense global warming, reaching a peak during the Palaeocene–Eocene Thermal Maximum (PETM), 56 my ago. The warmest global climate of the past 66 my occurred during the early Eocene epoch (about 56 to 48 mya) when megathermal floral elements, including palms, reached Antarctica. The increase in temperatures led to a rise in sea level, turning Europe into an archipelago. Data regarding the early Eocene herpetofaunas are scant, but the locality of Dormaal in Belgium represents one of the rare exceptions. The lizards consist of gekkotans, acrodontan and pleurodontan iguanians, anguimorphs such as glyptosaurines and the varanid Saniwa. These groups are believed to be thermophilic, and their appearance in this high latitude locality indicates that the tropics were expanded during this time. Some of these records also represent first appearances of these clades in Europe. Among them, a new iguanian taxon is represented by a unique tooth morphology – the teeth are bifurcated – indicating a specialization on trophic resources. However, because terrestrial ecosystems changed substantially during the Palaeogene, this might have caused higher extinction risk relative to generalists (e.g., the iguanian Geiseltaliellus). Understanding this geological epoch is relevant for present global climate change, including sea level rise, as well as the expansion of distribution of thermophilic taxa, including parasites that cause serious infectious diseases such as malaria.

Article Reference Dr Claude Massin (25/08/1948—04/09/2021), in Memoriam
This contribution provides an overview of the scientific career of the late Dr Claude Massin (1948–2021), listing his scientific activities (academic career, participation to and organization of expeditions and scientific conferences, publications) as well as the taxa he described as new to science and the eponyms that were dedicated to him. The scientific career of Claude Massin is briefly sketched against the background of the personal family-life.

Article Reference Early Bronze Age population substructure in the Khabur basin: preliminary evidence from Tell Brak, Tell Arbid and Tell Barri (Syria)
Bioarchaeological studies of human remains examine past populations through their mortuary, biological, and socio-cultural contexts. Biological distance, or biodistance, analyses use both genetic and phenetic data to investigate biological relatedness. Biodistance studies frequently employ phenotypic characteristics, or the physical expression of genetic traits that can serve as a proxy for aDNA, to understand evolution, migration, kinship and social organisation. We used phenotypic variation in dental morphology to investigate the population history of the Khabur basin in Syria, during an important period of urbanisation in the Early Bronze Age (EBA, circa 3000-2100 BCE) that shaped the political, social, and economic history of ancient Mesopotamia. Non-metric dental traits from three EBA sites, Tell Brak (n=77), Tell Barri (n=16) and Tell Arbid (n=17), were recorded using the Arizona State University Dental Anthropology System (ASUDAS). Individuals from the sites were compared using the Gower distance matrix and Mean Measure of Divergence (MMD) to examine the difference between sites as population groups. The results suggest that while sites were ancestrally similar, the observed heterogeneity between sites and was related to the socio-political nature of the community. The greatest variation was observed for the samples from Tell Brak and Tell Barri, the capital and the second-rank administrative centre, respectively. Although Tell Arbid showed less variability, some population segmentation was observed between different burial loci.

Article Reference Early Byzantine fish consumption and trade revealed by archaeoichthyology and isotopic analysis at Sagalassos, Turkey
We document the dietary and economic role of fish at Sagalassos, a town in ancient Pisidia (southwest Turkey) for the Early Byzantine period (c. 550 – 700 CE) through a detailed analysis of animal bones and stable isotopes. The role of fish in the diet is quantified, for the first time, based on large samples of sieved remains retrieved during the excavation of a number of spaces in an urban residence. The table and kitchen refuse from the mansion shows that fish was a regular part of the diet. However, past isotopic work focused on human individuals excavated in the city’s necropolises, slightly postdating the faunal remains examined, did not reflect this consumption of aquatic food. The studied assemblage comprises at least 12 different fish taxa, including five marine species, a Nilotic fish and six Anatolian freshwater species. Since the origin of the freshwater fishes could not be unambiguously determined by zoogeography alone, we analyzed carbon, nitrogen and sulphur stable isotope ratios in archaeological fish bones from Sagalassos as well as in bones of modern fish collected at different sites in Turkey. We show that most freshwater fish, i.e., all cyprinid species, came from Lake Eğirdir. No evidence was found for fish from the local Aksu River basin. The exact origin of pike, which account for 3% of all freshwater fish, could not be directly determined due to a shortage of modern comparative data. Using the data obtained on the provenance of the fish, the ancient trade routes possibly used in the Early Byzantine period are reconstructed using a combination of archaeological, numismatic and historical data on past commercial relations.

Article Reference Early Palaeozoic ocean anoxia and global warming driven by the evolution of shallow burrowing
The evolution of burrowing animals forms a defining event in the history of the Earth. It has been hypothesised that the expansion of seafloor burrowing during the Palaeozoic altered the biogeochemistry of the oceans and atmosphere. However, whilst potential impacts of bioturbation on the individual phosphorus, oxygen and sulphur cycles have been considered, combined effects have not been investigated, leading to major uncertainty over the timing and magnitude of the Earth system response to the evolution of bioturbation. Here we integrate the evolution of bioturbation into the COPSE model of global biogeochemical cycling, and compare quantitative model predictions to multiple geochemical proxies. Our results suggest that the advent of shallow burrowing in the early Cambrian contributed to a global low-oxygen state, which prevailed for ~100 million years. This impact of bioturbation on global biogeochemistry likely affected animal evolution through expanded ocean anoxia, high atmospheric CO2 levels and global warming.
