RESUMO
The role of boron in terrestrial plant physiology is diverse and increasingly well understood, but its role in marine aquatic eukaryotes is less clear. Our research reveals a distinctive and large offset in boron isotopes from seawater, irrespective of seaweed type or season. We show that the offset is consistent with the incorporation of borate from seawater. Boron is a known micronutrient in plants but very few studies have used boron isotopes to investigate boron's role in plant physiology. Seaweed, as the most primitive multicellular plant, has an important role in investigating wider plant adaptations that use boron to meet functional needs. Furthermore, seaweed and other plants are a key base nutrient provider in food webs, supplying boron to consumers and playing a critical role in boron environmental cycling.

We explore the ways in which residents of Neolithic Çatalhöyük in Anatolia differentiated themselves as well as the ways in which they did not. We integrate numerous data sets in order to assess patterns of inequality (A) across buildings with contemporaneous occupations, (B) between buildings that did or did not burn at abandonment, and (C) through time. We use Gini coefficients so as to maximize comparability with other studies of inequality in the ancient and modern worlds, discussing the underlying data and our results to clarify and enhance the value of the quantitative analyses. We evaluate whether or not trajectories of inequality align across data sets in order to determine how far success in one realm correlated with success in another. Our results indicate no unified trajectory of inequality through time. We perceive broadly similar access to staple foods, but not to goods less directly related to survival; relatively elevated income inequality during the middle portion of the site's occupation, plausibly deliberately tamped down; and no evidence for institutionalized or lasting economic or social inequality. These findings shed light on Neolithic social dynamics and also contribute to broader discussions of inequality and the social ramifications of early agropastoralism.

The futures of human and nonhuman primates are closely tied in protected areas. Understanding this interconnectedness is especially urgent in Madagascar, one of the world's most impoverished biodiversity hotspots. Yet, no study has evaluated the relationship between poverty and lemur hunting and consumption using a composite poverty metric that includes health, education, and living standards. To address this gap, and to inform primate conservation practice and policy, we administered annual surveys to 81 households over six consecutive months (September 2018 to March 2019) in a village on the border of Kirindy Mitea National Park, Madagascar. We observed extreme deprivation scores across multiple dimensions of poverty and identified ninety-five percent of households as 'impoverished'. Of these, three-quarters (77%) of households were identified as being in 'severe poverty'. One-fifth (19%) of all households hunted lemurs and half (49%) of households consumed lemurs. While poverty eradication is an urgent need in communities around Kirindy Mitea National Park, our findings show no relationship between poverty and lemur hunting and consumption, perhaps due to the lack of variance in poverty. Our results highlight the need to investigate other contributory factors to lemur hunting and consumption locally. Because food insecurity is a known driver of lemur hunting and consumption among the study community, and because domestic meats can be preferred over protected species, we recommend testing the efficacy of livestock interventions near Kirindy Mitea National Park.
