The detritivorous fish, gizzard shad (Dorosoma cepedianum), provides nutrients to phytoplankton in reservoirs by ingesting organic detritus associated with sediments and excreting substantial quantities of nutrients such as N and P in soluble forms that are highly available to phytoplankton, We estimated nutrient excretion by gizzard shad in a eutrophic(More)

The inclusive single and double differential cross-sections for neutral and charged current processes with four-momentum transfer squared É ¾ between ½½¼ and ¿¼ ¼¼¼ Î ¾ and with Bjorken Ü between ¼¼¼¿¾ and ¼ are measured in · Ô collisions. The data were taken with the H1 detector at HERA between 1994 and 1997, and they correspond to an integrated luminosity(More)
The inclusive e + p single and double differential cross sections for neutral and charged current processes are measured with the H1 detector at HERA. The data were taken in 1999 and 2000 at a centre-of-mass energy of √ s = 319 GeV and correspond to an integrated luminosity of 65.2 pb −1. The cross sections are measured in the range of four-momentum(More)
The bighead (Hypothalmichthys nobilis) and silver carp (H. molitrix) have invaded much of the Mississippi River. It is unclear how reproduction in northern impounded pools of the Upper Missis-sippi River System (UMRS) compares to unim-pounded (open) southern reaches. During spring through summer 2005 and 2006 and once in spring 2007, we quantified larval(More)
The elastic electroproduction of mesons is studied at HERA with the H1 detector for a photon virtuality in the range ½ É ¾ ¼ Î ¾ and for a hadronic centre of mass energy in the range ¿¼ Ï ½½¼ GeV. The shape of the () mass distribution in the resonance region is measured as a function of É ¾. The full set of spin density matrix elements is determined, and(More)

Measurements of ep scattering with squared 4{momentum transfer Q 2 up to 35000 GeV 2 are compared with the expectation of the standard deep-inelastic model of lepton{nucleon scattering (DIS). For Q 2 > 15000 GeV 2 , N obs = 12 neutral current candidate events are observed where the expectation is N DIS = 4:71 0:76 events. In the same Q 2 range, N obs = 4(More)
Photoproduction of 2-jet events is studied with the H1 detector at HERA. Parton cross sections are extracted from the data by an unfolding method using leading order parton-jet correlations of a QCD generator. The gluon distribution in the photon is derived in the fractional momentum range 0:04 x 1 at the average factorization scale 75 GeV 2. H1(More)
Cross sections for the production of two isolated muons up to high di-muon masses are measured in ep collisions at HERA with the H1 detector in a data sample corresponding to an integrated luminosity of 71 pb −1 at a centre of mass energy of √ s = 319 GeV. The results are in good agreement with Standard Model predictions, the dominant process being(More)
An analysis is presented of scaling violations of the proton structure function F 2 (x; Q 2) measured with the H1 detector at HERA in the range of Bjorken x values between x = 310 ?4 and 10 ?2 for four-momentum transfers Q 2 larger than 8.7 GeV 2. The structure function F 2 (x; Q 2) is observed to rise linearly with lnQ 2. Under the assumption that the(More)
