Association between substituting macronutrients and all-cause mortality: a network meta-analysis of prospective observational studies.

Background: Suboptimal diet quality is a key risk factor for premature death. Assuming relatively stable energy intake among individuals, changes in nutrient intakes occur by exchanging different nutrients. Therefore we aimed to examine the association of isocaloric substitution of dietary (macro)nutrients with all-cause mortality using network meta-analysis (NMA).

Mesoamerican urbanism revisited: Environmental change, adaptation, resilience, persistence, and collapse.

Urban adaptation to climate change is a global challenge requiring a broad response that can be informed by how urban societies in the past responded to environmental shocks. Yet, interdisciplinary efforts to leverage insights from the urban past have been stymied by disciplinary silos and entrenched misconceptions regarding the nature and diversity of premodern human settlements and institutions, especially in the case of prehispanic Mesoamerica. Long recognized as a distinct cultural region, prehispanic Mesoamerica was the setting for one of the world's original urbanization episodes despite the impediments to communication and resource extraction due to the lack of beasts of burden and wheeled transport, and the limited and relatively late use of metal implements.

Shifts in the conflict-coexistence continuum: Exploring social-ecological determinants of human-elephant interactions.

In Morogoro Region of south-central Tanzania, loss of crops and safety concerns due to elephants compromises livelihoods in many rural communities relying on subsistence agriculture. Using a social-ecological system framework to examine conflict-coexistence between people and elephants, this paper explores drivers that influence human-elephant interaction and subsistence farmer attitudes towards elephants in 10 villages from three different districts. Surveys and interviews document experiences interacting with elephants along with direct and indirect costs incurred in sharing the landscape, revealing different tolerance levels by residents of subject communities towards elephants that have important implications for elephant conservation.

Linguistic diversity and conservation opportunities at UNESCO World Heritage Sites in Africa.

Africa contains much of Earth's biological and cultural-linguistic diversity, but conserving this diversity is enormously challenging amid widespread poverty, expanding development, social unrest, and rapidly growing human population. We examined UNESCO (United Nations Educational, Scientific and Cultural Organization) Natural World Heritage Sites (WHSs) on continental Africa and nearby islands-48 protected areas containing globally important natural or combined natural and cultural resources-to gauge the potential for enlisting Indigenous peoples in their conservation. We used geographic information system technology to identify instances where Natural WHSs co-occur with Indigenous languages, a key indicator of cultural diversity.

Co-occurrence of linguistic and biological diversity in biodiversity hotspots and high biodiversity wilderness areas.

As the world grows less biologically diverse, it is becoming less linguistically and culturally diverse as well. Biologists estimate annual loss of species at 1,000 times or more greater than historic rates, and linguists predict that 50-90% of the world's languages will disappear by the end of this century. Prior studies indicate similarities in the geographic arrangement of biological and linguistic diversity, although conclusions have often been constrained by use of data with limited spatial precision.

Agricultural capacity and conservation in high biodiversity forest ecosystems.

Agricultural development is a leading cause of habitat destruction that increasingly threatens global biodiversity. To help understand the likelihood and implications of agricultural expansion in areas of high conservation importance, this article examines agricultural suitability in forested portions of biodiversity hotspots and tropical wilderness areas, regions with especially rich concentrations of species found nowhere else. The study employs geographic information system technology to examine suitability for six crop categories in selected conservation localities worldwide: those portions of regions containing high biodiversity, protected areas (e.

Changing migration patterns in the Federated States of Micronesia.

"This article traces the changing role of migration in the Federated States of Micronesia during the twentieth century. We begin with a brief geographical, historical, and cultural overview of each state in the country, summarizing demographic change over the past 70 years and providing a foundation for understanding much of the area's past and present human mobility. Attention then turns to migration within the Federated States, focusing on data from censuses conducted in 1930, 1973, and 1980 and using supplemental information when possible.

Changing regional demography in the Federated States of Micronesia: contrasting planning challenges in an emerging Pacific nation.

"Island nations consisting of small landmasses separated by large expanses of ocean face particularly severe challenges in their quest for economic and social development. In this paper, planning concerns in one such nation, the Federated States of Micronesia (FSM), are examined. The study opens with a description of each of the four separate states in the FSM.
