Contrasting the influences of stream inputs and landscape position on bacterioplankton community structure and dissolved organic matter composition in high-elevation lake chains
Contrasting landscape position
2014/4/18
We examined bacterioplankton community composition (BCC; using polymerase chain reaction-based
phylogenetic fingerprinting) and the composition of dissolved organic matter (DOM; using scanning fluoro...
Ecological, landscape, and climatic regulation of sediment geochemistry in North American sockeye salmon nursery lakes: Insights for paleoecological salmon investigations
sediment geochemistry Ecological landscape climatic
2014/4/17
We used multiple linear regressions across a Northeast Pacific region 56-lake set to examine the influence of
sockeye salmon spawner densities and limnological, climatic, and watershed characteristic...
Fast growth and turnover of chironomid assemblages in response to stream phosphorus levels in a tropical lowland landscape
Fast growth turnover of chironomid assemblages
2014/4/23
We studied the response of a dominant primary consumer, larval Chironomidae (Diptera), to phosphorus (via a
microbial response) across eight detritus-based streams spanning a gradient in soluble reac...
BOOK REVIEW——The Silent Landscape: The Scientific Voyage of the HMS Challenger
Landscape scientists science writer the ocean the crew
2015/7/29
In The Silent Landscape, scientist and science writer Richard Corfield relates the story of one of the most important scientific expeditions of the 19th Century, an expedition that would forever chang...
Nutrient variations in boreal and subarctic Swedish rivers: Landscape control of land– sea fluxes
boreal and subarctic Swedish land– sea fl uxes
2014/5/19
We examined the hypothesis that the extent of vegetation cover governs the fluxes of nutrients from boreal and
subarctic river catchments to the sea. Fluxes of total organic carbon (TOC) and di...
Landscape variation in phosphorus concentration and effects on detritus-based tropical streams
Landscape variation phosphorus concentration on detritus-based tropical streams
2014/5/26
Landscape-scale variation in streamwater phosphorus (P) concentration can affect aquatic food webs. Such variation occurs naturally in streams at La Selva Biological Station in Costa Rica due to spati...
Landscape effects of climate, agriculture, and urbanization on benthic invertebrate communities of Canadian prairie lakes
Landscape effects of climate, agriculture, and urbanization benthic invertebrate communities Canadian prairie lakes
2014/5/26
Paleoecological analyses of fossil chironomid assemblages from eight lakes of the Qu’Appelle Valley, Saskatchewan, Canada, were used to quantify the relative influence of climate, resource use, a...
The influence of watershed land use on lake N : P in a predominantly agricultural landscape
watershed land lake N : P a predominantly agricultural
2014/6/9
This study tests the hypothesis that lakes in watersheds dominated by row-crop agriculture (e.g., maize or soybeans) have systematically higher N: P than lakes in watersheds with large tracts of pastu...
