Isoprene (2-methyl-1,3-butadiene) is emitted in vast quantities (>500 Tg C yr -1 ). Most isoprene by trees, but there still incomplete understanding of the diversity sources. The reactivity atmosphere has potential implications for both global warming and cooling, with human health also arising from isoprene-induced ozone formation urban areas. emissions terrestrial environments have been st...

The Surface Biology and Geology (SBG) investigation will create global maps of spectral surface reflectance emissivity at a cadence 16 days or better, with coverage to address questions about Earth's geology, cryosphere ecosystems. revolutionary potential poses commensurate challenge: creating contiguous free from regional biases induced by atmosphere, observation geometry, inversion error. Thi...

Abstract Plastics are receiving widespread attention as an environmental contaminant, but their role in disrupting the behavior and physiology of organisms remains neglected. Here, I highlight growing evidence that plastics have pervasive, non‐toxic effects aquatic ecosystems, especially on feeding interactions. These ultimately consequences for flow energy through food webs productivity entire...

Global change is altering the movement of materials across landscapes in ways that likely have major consequences for the functioning and stability of ecosystems. For example, the export of dissolved organic carbon (DOC) from terrestrial to aquatic ecosystems is increasing globally. This browning phenomenon is expected to alter the stability of recipient aquatic ecosystems, but theory provides ...

Aquatic macroinvertebrates are involved in numerous processes within aquatic ecosystems. They often have important effects on ecosystem processes such as primary production (via grazing), detritus breakdown, and nutrient mineralization and downstream spiraling. The functional feeding groups (FFG) classification was developed as a tool to facilitate the incorporation of macroinvertebrates in stu...

Resource pulses affect productivity and dynamics in a diversity of ecosystems, including islands, forests, streams, and lakes. Terrestrial and aquatic systems differ in food web structure and biogeochemistry; thus they may also differ in their responses to resource pulses. However, there has been a limited attempt to compare responses across ecosystem types. Here, we identify similarities and d...

Microorganisms have been recognized as central to nutrient mineralization and recycling in aquatic ecosystems since Lindeman's groundbreaking work on the trophic-dynamic aspect of ecology (Lindeman, 1942). Since the seventies, the development of new analytical technologies led to important conceptual perspectives, such as the microbial loop and the microbial food web (as summarized elsewhere, e...
