Assessing ecological responses to catastrophic amphibian declines: Patterns of macroinvertebrate production and food web structure in upland Panamanian streams
Assessing ecological responses catastrophic amphibian declines
2014/4/17
As part of the Tropical Amphibian Declines in Streams (TADS) project, we estimated macroinvertebrate
production and constructed quantitative food webs for four headwater stream reaches in the Panaman...
Controls on spatial and temporal variation of nutrient uptake in three Michigan headwater streams
Controls on spatial nutrient uptake
2014/4/22
We measured whole-stream uptake of ammonium (NHz
4
), nitrate (NO{
3
), and phosphate (as soluble reactive
phosphorus [SRP]) in two reaches of three forested headwater streams eight times from Ma...
We investigated physical, chemical, and biological variables contributing to biochemical oxygen demand (BOD)
in 17 North Carolina lotic and lentic water bodies affected by mild to severe hypoxia. Phy...
The influence of filter-feeding benthic macroinvertebrates on the transport and deposition of particulate organic matter and diatoms in two streams
fi lter-feeding benthic macroinvertebrates diatoms
2014/6/9
The transport and deposition of particulate organic matter (POM) in streams has received much attention in recent
years. As with many ecosystem processes, determining the relative importance of physi...
Orientation in complex chemical landscapes: Spatial arrangement of chemical sources influences crayfish food-finding efficiency in artificial streams
complex chemical landscapes chemical sources infl uences
2014/5/30
Fluid dynamics has been shown to alter ecologically important behaviors of aquatic organisms orienting to distant
chemical sources. Because the fluid dynamics and chemical plumes change across ...
Effects of land use and riparian flowpath on delivery of dissolved organic carbon to streams
riparian fl owpath dissolved organic carbon
2014/5/30
A set of near-stream flowpaths in pasture, native forest and exotic pine plantations in New Zealand was sampled
to describe differences in dissolved organic carbon (DOC). The quantity and bioav...
