Nonlinear effects of consumer density on multiple ecosystem processesAmanda J Klemmer
Biology Department, Allegheny College, Meadville, PA 16225, USA
J Anim Ecol 81:770-80. 2012..Given the ubiquity of negative density dependence in nature, nonlinear consumer density-ecosystem function relationships should be common across species and ecosystems...- Estimating Brownian motion dispersal rate, longevity and population density from spatially explicit mark-recapture data on tropical butterfliesJarle Tufto
Center for Conservation Biology, Department of Mathematical Sciences, Norwegian University of Science and Technology, Trondheim, Norway
J Anim Ecol 81:756-69. 2012..However, higher dispersal rate also decreases longevity, thus explaining the surprising observation of a negative correlation between wing length and longevity... 
Analysis of genetic structure and dispersal patterns in a population of sea beetJ Tufto
Norwegian Institute for Nature Research, 7005 Trondheim, Norway
Genetics 149:1975-85. 1998..Finally, we note that the data also appear to contain some information about this ratio...
Quantitative genetic models for the balance between migration and stabilizing selectionJ Tufto
Department of Mathematical Sciences Lade section, Norwegian University of Science and Technology, 7491 Trondheim, Norway
Genet Res 76:285-93. 2000....- Effective size in management and conservation of subdivided populationsJarle Tufto
Department of Mathematical Sciences, Norwegian University of Science and Technology, 7491 Trondheim, Norway
J Theor Biol 222:273-81. 2003..It is shown that the total effective size can be reduced by several orders of magnitude if the captive component of a population is much smaller than the wild component, even with symmetric backward migration... - Dispersal of introduced house sparrows Passer domesticus: an experimentSigrun Skjelseth
Department of Biology, Population Biology Centre, Norwegian University of Science and Technology, 7491 Trondheim, Norway
Proc Biol Sci 274:1763-71. 2007..These results suggest that the distribution and frequency of introduced individuals may be predicted by their sex ratio as well as their phenotypic characteristics... - A parametric model for estimation of dispersal patterns applied to five passerine spatially structured populationsJarle Tufto
Department of Mathematical Sciences, Norwegian University of Science and Technology, 7491 Trondheim, Norway
Am Nat 165:E13-26. 2005..In estimating the dispersal standard deviation, however, incorrect assumptions about the degree of leptokurtosis can lead to a large bias in estimation and predictions... - The effect of collagenase and hyaluronidase on transient perfusion in human osteosarcoma xenografts grown orthotopically and in dorsal skinfold chambersIngunn Tufto
Department of Physics, The Norwegian University of Science and Technology, Trondheim, Norway
Anticancer Res 27:1475-81. 2007..The purpose of the present work was to investigate whether collagenase or hyaluronidase had any effects on transient perfusion and/or changes in vascular areas... - Sexual variation in heritability and genetic correlations of morphological traits in house sparrow (Passer domesticus)H Jensen
Department of Biology, Realfagbygget, Norwegian University of Science and Technology, Trondheim, Norway
J Evol Biol 16:1296-307. 2003..Hence, our results suggest that sex-specific additive genetic variances and covariances, although ignored in most studies, should be included when making predictions of evolutionary changes from standard quantitative genetic models... - Population dynamical consequences of climate change for a small temperate songbirdB Saether
Department of Zoology, Norwegian University of Science and Technology, N 7491 Trondheim, Norway
Science 287:854-6. 2000.... - Does selection or genetic drift explain geographic differentiation of morphological characters in house sparrows Passer domesticus?Anna M Holand

Norwegian Institute for Nature Research, Trondheim, Norway
Genetics 144:1911-21. 1996..Possible ecological extensions of the model are discussed... - Gene flow from domesticated species to wild relatives: migration load in a model of multivariate selectionJarle Tufto
Centre for Conservation Biology, Department of Mathematical Sciences, Norwegian University of Science and Technology, 7491 Trondheim, Norway
Evolution 64:180-92. 2010..For realistic parameter values, however, the effect of correlational selection on the load is small, suggesting that simpler one-dimensional models may still be adequate in terms of predicting mean population fitness and viability... - Natural selection acts on Atlantic salmon major histocompatibility (MH) variability in the wildElvira de Eyto
Aquaculture and Catchment Management Services, Marine Institute, Newport, Co Mayo, Ireland
Proc Biol Sci 274:861-9. 2007..We conclude that natural or hatchery populations have the best chance of dealing with episodic and variable disease challenges if MH genetic variation is preserved both within and among populations...
