HOST PLANT GENOTYPE INFLUENCES SURVIVAL OF HYBRIDS BETWEEN EUROSTA SOLIDAGINIS HOST RACES

Autor: James V. Craig, Joanne K. Itami, Timothy P. Craig

Publikováno v: Evolution. 61:2607-2613

Extrinsic, host-associated environmental factors may influence postmating isolation between herbivorous insect populations and represent a fundamentally ecological cause of speciation. We investigated this issue in experiments on hybrids between the

Summary 1. A series of experiments was conducted to measure the impact of plant genotype, plant growth rate, and intraspecific competition on the oviposition preference and offspring performance of the host races of Eurosta solidaginis (Diptera: Teph

Environmental design and its evaluation for intensively housed animals

Autor: Glen McBride, James V. Craig

Publikováno v: Applied Animal Behaviour Science. 14:211-224

It is argued that applied ethology has emerged as an empirical science with a limited base of theory. Two models are presented and used to examine problems of evaluation of husbandry design. The first model, of the process of adaptation to environmen

Behavioral and Genetic Adaptation of Laying Hens to High-Density Environments

Autor: James V. Craig

Publikováno v: BioScience. 32:33-37

High-density, barren-cage environments are provided for most hens kept for egg production. Beak trimming, toenail removal, decreasing group size, increasing space per hen, and certain alterations in cage design increase well-being and productivity of
