Seasonal analysis of protistan community structure and diversity at the USC Microbial Observatory (San Pedro Channel, North Pacific Ocean)
protistan community structure USC Microbial Observatory
2014/4/17
The structure and genetic diversity of marine protistan assemblages were investigated in the upper 500 m of the
water column at a Pacific Ocean time-series station off the coast of Southern Californi...
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...
Research on numerical welding experiment of a thick spherical shell structure
welding program thermal-structure coupling analysis residual stress residual deformation thick spherical shell structure
2011/9/14
In this paper,in order to predict the residual deformation of thick spherical structure,a welding program is compiled in APDL language based on Ansys and a numerical welding experiment of a welding ex...

Flooding and arsenic contamination: Influences on ecosystem structure and function in an Appalachian headwater stream
Flooding arsenic contamination ecosystem structure
2014/4/22
We investigated the influence of flooding and chronic arsenic contamination on ecosystem structure and
function in a headwater stream adjacent to an abandoned arsenic (As) mine using an upstream (ref...
Potamoplankton size structure and taxonomic composition: Influence of river size and nutrient concentrations
Potamoplankton size taxonomic composition
2014/4/30
We measured the size structure and taxonomic composition of phytoplankton in temperate rivers during base
flows of summer to investigate the influence of river size, ambient nutrient conc...
Spatial structure of the dominant basin-scale internal waves in Lake Kinneret
dominant basin-scale internal waves Lake Kinneret
2014/4/23
Field data and numerical simulations were used to investigate the effects of basin shape, continuous stratification,
and rotation on the three-dimensional structure of the dominant natural basi...
A species invasion mediated through habitat structure, intraguild predation, and parasitism
habitat structure intraguild predation
2014/5/19
With field, laboratory, and modeling approaches, we examined the interplay among habitat structure, intraguild
predation (IGP), and parasitism in an ongoing species invasion. Native Gammarus du...
Changes to zooplankton community structure following colonization of a small lake by Leptodora kindti
zooplankton colonization
2014/5/16
The predaceous cladoceran Leptodora kindti (Focke) became established in Third Sister Lake, Michigan, after
individuals escaped from experimental enclosures in 1987. By 1988, the Leptodora population...
