1. Numerous studies have reported the effects of learning or experience on parasitoid host preference and location. However, the integration of pre-imaginal and adult experiences on the subsequent host preference and adult/offspring performance has been rarely tested in host–parasite interactions. 2. We present direct evidence that theses two kinds of experiences affect host preference and rela...

Many animals exhibit social plasticity - changes in phenotype or behaviour in response to experience with conspecifics that change how evolutionary processes like sexual selection play out. Here, we asked whether social plasticity arising from variation in local population density in male advertisement signals and female mate preferences influences the form of sexual selection. We manipulated l...

Feeding habits of yellowfin seabream, Acanthopagrus latus was investigated in coastal waters of the Northern Persian Gulf. This investigation was conducted by monthly sampling of thirty fish from September 2011 through August 2012. Fish size ranged from 17.98 ± 2.07 to 32.31 ± 6.52 cm in total length and from 134.01 ± 45.62 to 720.46 ± 292.58 g in weight. The highest value of gastro-somatic ind...

Background: Proposing an appropriate model of feeding behavior to mothers plays an important role in creating an accurate child feeding conduct. Studies have shown that mothers have low level of knowledge and practice regarding their childrens’ nurishment. Newsletter is an educational media providing families with easy access to information resources. Group discussion is one of the best ways to...

Switchgrass, Panicum virgatum L., is a perennial warm-season grass that has been identified as a model species for the development of bioenergy crops in the United States. The objectives of this research were to evaluate selected switchgrass populations for host suitability and differential resistance to potential aphid pests, determine the categories (antibiosis, antixenosis, and/or tolerance)...

The Pacific abalone, Haliotis discus hannai, is a highly valued and industrially important aquaculture species with growing demands of the expanding abalone industry. To explore feasibility using brown alga, Sargassum horneri, as potential substitute for feed, it to identify feed preference attractant effect S. horneri on abalone. Our experiments indicated that feeding-associated movement could...

Potential hosts for infective juveniles of entomopathogenic nematodes can vary considerably in quality based on the characteristics of the host species/stage, physiological status (e.g. stress, feeding on toxins), and infection status (heterospecific or conspecific infection). In this study, we investigated responses of the entomopathogenic nematode Steinernema riobrave to hosts (Galleria mello...

Early feeding experiences, e.g. related to milk feeding, can affect later food and taste preferences. However, consequences of breast-feeding on taste acceptance are under-investigated. The objective of the present study was to examine the impact of exclusive breast-feeding duration (DEB) on taste acceptance at 6 and 12 months in the same infants (n 122). Mothers recorded the DEB. Acceptance of...
