Identifying the Environmental Drivers of Spatial Variability in Zooplankton Community Grazing Dynamics

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Biogeochemical models used to estimate carbon export fluxes are highly sensitive to their parameterization of zooplankton grazing dynamics. Zooplankton grazing dynamics have been shown to vary spatially, however it is less clear how they are responding to underlying environmental drivers.

Long-Term Warming in Alaska Enlarges the Diazotrophic Community in Deep Soils

mBio, 2019
Tundra ecosystems are typically carbon (C) rich but nitrogen (N) limited. Since biological N2 fixation is the major source of biologically available N, the soil N2-fixing (i.e., diazotrophic) community serves as an essential N supplier to the tundra ...

A Short Comparison of Two Marine Planktonic Diazotrophic Symbioses Highlights an Un-quantified Disparity

Frontiers in Marine Science, 2018
Some N2-fixing cyanobacteria form symbiosis with diverse protists. In the plankton two groups of diazotrophic symbioses are described: (1) a collective group of diatoms which associate with heterocystous cyanobacteria (Diatom Diazotroph Associations, DDA)

Ca. Nitrososphaera and Bradyrhizobium are inversely correlated and related to agricultural practices in long-term field experiments

Frontiers in Microbiology, 2013
Agricultural land management, such as fertilization, liming, and tillage affects soil properties, including pH, organic matter content, nitrification rates, and the microbial community.

Field Assessment of Biochar Interactions With Chemical and Biological N Fertilization in Pointed White Cabbage

GCB Bioenergy
The interaction of biochar with mineral fertilization has attracted attention as a strategy to reduce N losses and enhance nitrogen use efficiency. In this study, we investigated the coapplication of biochar with two optimized fertilization strategies ...

Distinct Microbial Community of Phyllosphere Associated with Five Tropical Plants on Yongxing Island, South China Sea

Microorganisms, 2019
The surfaces of a leaf are unique and wide habitats for a microbial community. These microorganisms play a key role in plant growth and adaptation to adverse conditions, such as producing growth factors to promote plant growth and inhibiting pathogens to
