Biological systems are composed of heterogeneous populations of cells that
intercommunicate to form a functional living tissue. Biological function varies greatly across …

Developments in forensic mass spectrometry tend to follow, rather than lead, the
developments in other disciplines. Examples of techniques having forensic potential born …

In this chapter, we discuss post-photosynthetic processes that affect intra-annual variation in
the stable isotopes of tree rings, such as timing of cell formations and turnover of stored …

The stable isotopes of organic matter can provide valuable information on carbon cycling
dynamics, microbial metabolisms, and past climates. Since bulk measurements may mask …

Understanding how trees prioritize carbon gain at the cost of drought vulnerability under
severe drought conditions is crucial for predicting which genetic groups and individuals will …

Stable isotope ratio analysis of tree rings has been widely and successfully applied in recent
decades for climatic and environmental reconstructions. These studies were mostly …

The rhizosphere embodies a complex biogeochemical zone with enhanced rates of nutrient
exchange between plants, soil, and microbial communities. Understanding controls on …

The rhizosphere is a highly dynamic zone bridging plant roots with needed nutrient
resources in soil. While the rhizosphere may be small, it has a disproportionally large impact …

The stable 13C/12C isotope composition usually varies among different organic materials
due to isotope fractionation during biochemical synthesis and degradation processes. Here …

Productivity is a major determinant of ecosystem diversity. Microbial ecosystems are the
most diverse on the planet yet very few relationships between diversity and productivity have …
