ABSTRACT Neotropical seasonally dry biomes are amongst the world's most threatened ecosystems and are predicted to lose more biodiversity with climate change. The capacity of natural populations to respond to these changes depends on their genetic variation, but is poorly understood in most Neotropical seasonally dry forest species.

In the Northeastern US, short‐rotation willow biomass crops have the potential to serve as nurse crops that facilitate hardwood regeneration on former agricultural land to support afforestation efforts. Regeneration declines with distance from natural seed sources, but could be augmented with seeding/underplanting.

Phase Separation and Mechanical Properties in Si‐Poor Sodium‐Borosilicate Glasses
We demonstrate an unexpected phase separation and the related mechanical property enhancements in a sodium‐borosilicate glass. ABSTRACT Phase separation is a well‐known approach to increase the damage tolerance of oxide glasses. Here, we report the separation of a silicon‐ and boron‐rich phase in a Si‐poor sodium‐borosilicate glass.

ABSTRACT The rhizosphere harbours critical plant‐herbivore interactions often mediated by small lipophilic molecules (SLMs). Despite the agricultural importance of many soil‐dwelling insects, surprisingly little is known about chemically mediated belowground crop‐pest interactions. Root and shoot herbivores can influence these interactions by modifying

ABSTRACT Subaerial Pyroclastic Density Currents (PDCs) and Subaqueous Eruption‐Fed Density Currents (SEFDCs) produced during volcanic eruptions can present major hazards to surrounding communities and ecosystems. The bedforms deposited by these volcanic density currents can provide insights into the nature of transport and depositional processes, which
