Figure 7 in Mineralized-tissue histology reveals protracted life history in the Pliocene three-toed horse from Langebaanweg (South Africa)
Figure 7. Relationship between neonatal and adult body size in extant and extinct equids, with Eurygnathohippus hooijeri included for comparison. The perimeter of the neonatal line (NL; in millimetres) is plotted against body mass (in kilograms). Data on perimeter of the NL in Miocene European hipparionines come from the study by Orlandi-Oliveras et al. (2018), extant and extinct Equus from Nacarino-Meneses & Orlandi-Oliveras (2021). Body mass of Miocene European hipparionines comes from Orlandi-Oliveras et al. (2018), extant and extinct Equus from Ernest (2003) and Nacarino-Meneses & OrlandiOliveras (2021). A, metacarpi. B, metatarsi.

Mineral resources and the salience of ethnic identities
<p>This paper shows how ethnic identities may become more salient due to natural resources extraction. We combine individual data on the strength of ethnic – relative to national – identities with geo-localized information on the contours of ethnic homelands and on the timing and location of mineral resources exploitation in 25 African countries, from 2005 to 2015. Our strategy takes advantage of several dimensions of exposure to resources exploitation: time, spatial proximity, and ethnic proximity. We find that the strength of an ethnic group identity increases when mineral resource exploitation in that group’s historical homeland intensifies. We argue that<br> this result is at least partly rooted in feelings of relative deprivation associated with the exploitation of the resources. We show that such exploitation has limited positive economic spillovers, especially for members of the indigenous ethnic group; and that the link between mineral resources and the salience of ethnic identities is reinforced among members of powerless ethnic groups, and<br> groups with strong baseline identity feelings or living in poorer areas, or areas with a history of conflict. Put together, these finding suggest a new dimension of the natural resource curse: the fragmentation of identities, between ethnic groups and nations.</p>

Data for: Cover crop functional types differentially alter the content and composition of soil organic carbon in particulate and mineral-associated fractions
<p>Cover crops (CCs) can increase soil organic carbon (SOC) sequestration by providing additional OC residues, recruiting beneficial soil microbiota, and improving soil aggregation and structure. The various CC species that belong to distinct plant functional types (PFTs) may differentially impact SOC formation and stabilization. Biogeochemical theory suggests that selection of PFTs with distinct litter quality (C:N ratio) should influence the pathways and magnitude of SOC sequestration. Yet, we lack knowledge on the effect of CCs from different PFTs on the quantity and composition of physiochemical pools of SOC. We sampled soils under monocultures of three CC PFTs (legume [crimson clover]; grass [triticale]; and brassica [canola]) and a mixture of these three species, from a long-term CC experiment in Pennsylvania, USA. We measured C content in bulk soil and C content and composition in contrasting physical fractions: particulate organic matter, POM; and mineral-associated organic matter, MAOM. The bulk SOC content was higher in all CC treatments compared to the fallow. Compared to the legume, monocultures of grass and brassica with lower litter quality (wider C:N) had higher proportion of plant-derived C in POM, indicating selective preservation of complex structural plant compounds. In contrast, soils under legumes had greater accumulation of microbial-derived C in MAOM. Our results for the first time, revealed that the mixture contributed to a higher concentration of plant-derived compounds in POM relative to the legume, and a greater accumulation of microbial-derived C in MAOM compared to monocultures of grass and brassica. Mixtures with all three PFTs can thus increase the short- and long-term SOC persistence balancing the contrasting effects on the chemistries in POM and MAOM imposed by monoculture CC PFTs. Thus, despite different cumulative C inputs in CC treatments from different PFTs, the total SOC stocks did not vary between CC PFTs, rather PFTs impacted whether C accumulated in POM or MAOM fractions. This highlights that CCs of different PFTs may shift the dominant SOC formation pathways (POM vs. MAOM), subsequently impacting short- and long-term SOC stabilization and stocks. Our work provides a strong applied field test of biogeochemical theory linking litter quality to pathways of C accrual in soil.</p>
