Composition of chloroform extractable surface wax from fruit was determined by GC and GC/MS. The major components of Saskatoon berry wax were nonacosan‐10‐ol and nonacosane. Canadian sour cherry wax was enriched in the pentacyclic triterpenoids and haskap in nonacosan‐10‐ol and nonacosan‐5,10,‐diol. Red twinberry wax contained triterpenoids.

ABSTRACT Aim Biodiversity is declining at a rapid rate, and effective conservation necessitates understanding the drivers of species richness patterns at management‐relevant scales. Vegetation productivity data derived from satellite data estimate the available energy in ecosystems, allowing the generation of relevant indices that explain biodiversity ...

A novel “Cu‐mediated interstitial site engineering” strategy is introduced to thermodynamically stabilize hexagonal oxygen (hex‐O) configurations in oxygen‐containing titanium alloys. The hex‐O configuration activates multiple slip systems and enhances dislocation pinning via long‐range repulsion.

Abstract Earth's forests are major carbon sinks that slow human‐driven climate change, yet climate‐sensitive disturbances are increasing tree mortality and altering carbon cycling. We assessed how forest mortality influences the magnitude, phenology, and drivers of carbon fluxes across the conterminous United States.

Complex trajectories of tree growth in the southwestern United States after severe drought
Abstract Climate change driven extreme droughts have major impacts on forest ecosystems, including large‐scale mortality and reduced primary production, which feedback to affect the global carbon cycle. The long‐term impacts of extreme drought events on forest mortality, ecosystem responses, and recovery/post‐drought trajectories are poorly understood.

Biodiversity, ecosystem functioning, and classical biological control [PDF]
Increasing concern over worldwide loss of biodiversity has led ecologists to focus intently on how ecosystem functioning may depend on diversity. In applied entomology, there is longstanding interest in the issue, especially as regards the importance of ...
