Article
Terry D. Prowse, Auteur ; Frederick J. Wrona, Auteur ; James D. Reist, Auteur ; John E. Hobbie, Auteur ; Lucie M. J. Levesque, Auteur ; Warwick F. Vincent, AuteurLarge variations exist in the size, abundance and biota of the two principal categories of freshwater ecosystems, lotic (flowing water; e.g., rivers, streams, deltas and estuaries) and lentic (standing water; lakes, ponds and wetlands) found acr[...]
Article
Terry D. Prowse, Auteur ; Frederick J. Wrona, Auteur ; James D. Reist, Auteur ; John J. Gibson, Auteur ; John E. Hobbie, Auteur ; Lucie M. J. Levesque, Auteur ; Warwick F. Vincent, AuteurVarious types of ecosystem-based climate proxies have been used to assess past arctic change. Although lotic records are relatively poor because of the constant reworking of riverine material, high-quality lentic data have been assembled back to[...]
