This review points out the problem of processing multiple sensory inputs and provides evidence that generalists suffer a disadvantage compared with specialists with respect to efficiency of host plant choice and discrimination. The specialists' mechanisms for improved efficiency are discussed as well as some of the processes that may be selected to increase processing efficiency in generalists....

The rice stink bug, Oebalus pugnax (Fabricius) (Hemiptera: Pentatomidae: Carpocorini), though graminaceous, discriminates among its numerous host grass species. This could represent a feeding preference, it could be related to host suitability for growth and development. To clarify the role of host grass discrimination, two laboratory studies were conducted: (1) free-choice tests to evaluate pr...

Evolutionary hypotheses regarding the function of eggshell phenotypes, from solar protection through mimicry, have implicitly assumed that eggshell appearance remains static throughout the laying and incubation periods. However, recent research demonstrates that egg coloration changes over relatively short, biologically relevant timescales. Here, we provide the first evidence that such changes ...

Retinoic acid-inducible gene (RIG)-I-like receptors (RLRs) are cytosolic RNA helicases that sense viral RNA and trigger signaling pathways that induce the production of type I interferons (IFNs) and proinflammatory cytokines. RLRs recognize distinct and overlapping sets of viruses, but the mechanisms that dictate this specificity were unknown. A new study now provides evidence for size-based di...

There is little quantitative research regarding the causes and expression of prejudice and discrimination against Middle-Eastern Australians. We report two studies, one from the perspective of new settlers and a second from the perspective of host communities. The first found that Middle-Eastern Australians reported more discrimination compared with non-Middle-Eastern Australians. More discrimi...

Purpose Drawing on embeddedness theory, we examine how skilled immigrants' perceived brain-waste affects their social embeddedness. Social facilitates the acquisition of host country-specific human capital, which, in return, can accelerate transfer capital workplace. Design/methodology/approach In total, 397 immigrants Australia participated this study. We applied a set-theoretic approach to de...

Abstract Over the last decades, number of immigrants in Germany has been rising steadily. One result this is that currently, around 40% children country have immigrant parents. Existing studies report rather mixed results concerning their mental health outcomes. The present study provides some insight into factors affect population. We compared emotional and behavioral problems (assessed via SO...
