Effects of Brachypterolus pulicarius (L.) (Coleoptera: Nitidulidae) on Growth and Seed Production of Dalmatian toadflax, Linaria genistifolia ssp. dalmatica (L.) Maire and Petitmengin (Scrophulariaceae)

Autor: Robert M. Nowierski, Robert T. Grubb, Roger L. Sheley

Publikováno v: Biological Control. 23:107-114

The impact of the ovary-feeding beetle Brachypterolus pulicarius on the growth and reproduction of Dalmatian toadflax, Linaria genistifolia spp. dalmatica, was evaluated in greenhouse and field experiments. Studies were conducted with paired plants (

Autor: Bryan C. Fitzgerald, Robert M. Nowierski, Andre Gassmann, Massimo Cristofaro, Dieter Schroeder, Zheng Zeng

Publikováno v: Biological Control. 23:1-17

Biotic and abiotic factors can have a profound influence on the occurrence, species composition, structure, distribution, relative abundance, and dynamics of plant species and their associated natural enemies. Elucidation of some of the more relevant

Overwintering Mortality ofUrophora affinisandU. quadrifasciata(Diptera: Tephritidae) on Spotted Knapweed: Effects of Larval Competition Versus Exposure to Subzero Temperatures

Autor: Gregory J. Mcdermott, Robert M. Nowierski, Jim M. Story, Bryan C. Fitzgerald

Publikováno v: Environmental Entomology. 29:403-412

The overwintering survival of Urophora affinis Frauenfeld and U. quadrifasciata (Meigen) was examined in a 5-yr (1989–1993), multiple-site field study in western Montana. These two tephritid fly species are introduced biological control agents of s

COMPLEX POPULATION DYNAMICS IN THE REAL WORLD: MODELING THE INFLUENCE OF TIME-VARYING PARAMETERS AND TIME LAGS

Autor: Brian Dennis, Mark L. Taper, Zheng Zeng, William P. Kemp, Robert M. Nowierski

Publikováno v: Ecology. 79:2193-2209

We propose a class of complex population dynamic models that combines new time-varying parameters and second-order time lags for describing univariate ecological time series data. The Kalman filter and likelihood function were used to estimate parame
