Are Immigrants Positively or Negatively Selected? The Role of Immigrant Selection Criteria and Self-Selection [PDF]

This paper specifies and estimates a structural model of international migration using micro data. This provides a direct test of human capital theory that suggests that individuals respond to the earnings differentials across countries while making ...

GRB optical afterglow and redshift selection effects: The learning curve effect at work

, 2008
We show how the observed gamma ray burst (GRB) optical afterglow (OA) and redshift distributions are changing in time from selection effects. For a subset of {\it Swift} triggered long duration bursts, we show that the mean time taken to acquire ...

Identification of differential expression genes associated with host selection and adaptation between two sibling insect species by transcriptional profile analysis

BMC Genomics, 2013
Cotton bollworm (Helicoverpa armigera) and oriental tobacco budworm (Helicoverpa assulta) are noctuid sibling species. Under artificial manipulation, they can mate and produce fertile offspring.

Gut Microbiota Co-microevolution with Selection for Host Humoral Immunity

Frontiers in Microbiology, 2017
To explore coevolution between the gut microbiota and the humoral immune system of the host, we used chickens as the model organism. The host populations were two lines (HAS and LAS) developed from a common founder that had undergone 40 generations of ...

Infection Dynamics Vary between Symbiodinium Types and Cell Surface Treatments during Establishment of Endosymbiosis with Coral Larvae

Diversity, 2011
Symbioses between microbes and higher organisms underpin high diversity in many ecosystems, including coral reefs, however mechanisms underlying the early establishment of symbioses remain unclear.

Colonization of Three Maple Species by Asian Longhorned Beetle, Anoplophora glabripennis, in Two Mixed-Hardwood Forest Stands

Insects, 2013
Asian longhorned beetle (ALB), Anoplophora glabripennis (Motschulsky), is an invasive insect that has successfully established multiple times in North America. To investigate host colonization and reproductive success (exit holes/eggs), two ALB infested

Maladaptive host choice by an alien leaf miner Phyllonorycter leucographella (Lepidoptera: Gracillariidae) has the potential to limit its invasiveness

European Journal of Entomology, 2018
Alien phytophagous insects are often introduced along with their host plants, creating opportunities for troublesome invasions. Yet, not all of them are able to successfully colonize novel host plants. In this study, we investigated host selection by the

Host Selection of the giant willow aphid (Tuberolachnus salignus) [PDF]

, 2009
The giant willow aphid [Tuberolachnus salignus (Gmelin)] has recently become noteworthy as a potential pest species due to the increased uptake of willow, its host-plant, for use in growing biomass for energy production.
