Overcoming environmental constraints to high‐yielding eastern cottonwood productivity in the southeastern United States

Annals of Applied Biology, EarlyView.
The rising demand for biomass highlights Populus deltoides as a productive woody species. A 6‐year study in Sumter County, SC, assessed the effects of irrigation, fertilization, and clonal variation on growth and productivity. Eight clones were studied under two irrigation levels (33 and 1500 kPa) and nutrient rates (high: up to 182 kg N ha−1; low: 50%

Experience and self‐interest: Diverging responses to global warming

American Journal of Political Science, EarlyView.
Abstract People are increasingly feeling global warming's effects through extreme heat and natural disasters. How do these climate shocks affect political attitudes? We argue that the effect of climate‐related experiences depends significantly on self‐interest.

A practical, adaptive compliance management framework for improving marine protected area effectiveness

Conservation Biology, EarlyView.
Abstract Noncompliance regularly undermines the effectiveness of marine protected areas (MPAs) worldwide. The reasons for and drivers of noncompliance depend on the context (e.g., insufficient funding, capacity, neocolonialism, historical conflict), but the prevalent solution offered to curtail noncompliance tends to be more or better enforcement.

A tale of two microbialites: Stromatolites and microbially induced sedimentary structures

Sedimentology, EarlyView.
ABSTRACT Microbialites are biosedimentary structures built by microbial mats. Five microbialite groups are distinguished: stromatolites, thrombolites, dendrolites, leiloites and microbially induced sedimentary structures (MISS). This contribution discusses the two most abundant microbialite groups in marine settings, stromatolites and MISS.
