Can parasites halt the invader? Mermithid nematodes parasitizing the yellow-legged Asian hornet in France by Claire Villemant, Dario Zuccon, Quentin Rome, Franck Muller, George O. Poinar Jr, Jean-Lou Justine

“…Since its introduction in France 10 years ago, the yellow-legged Asian bee-hawking hornet Vespa velutina has rapidly spread to neighboring countries (Spain, Portugal, Belgium, Italy, and Germany), becoming a new threat to beekeeping activities. While introduced species often leave behind natural enemies from their original home, which benefits them in their new environment, they can also suffer local recruitment of natural enemies. …”

Orthogonal Dietary Niche Enables Reversible Engraftment of a Gut Bacterial Commensal by Kearney, Sean M, Gibbons, Sean Michael, Erdman, Susan E, Alm, Eric J

“…While probiotic or prebiotic approaches typically lead to a transient pulse in abundance of an organism, persistent establishment of an introduced species may require alternative strategies. Here, we introduce the concept of orthogonal niche engineering in the gut, where we include a resource typically absent from the diet, seaweed, to establish a customized niche for an introduced organism. …”

A tale of two species: the importance of native ecosystems for long-term conservation on Príncipe Island, Gulf of Guinea by Guilherme R.V. Rebelo, Filipa C. Soares, Martina Panisi, Yodiney dos Santos, Tania L.F. Bird, Frazer Sinclair, Jorge Palmeirim, Ricardo Faustino de Lima

“…We argue that their current distribution might be negatively affected by anthropogenic pressures, as both are harvested, and also because invasive alien species are expected to have deleterious effects on these species, although further studies are needed to clarify interactions between these native and introduced species. The diachronic stories of these species highlight an overlooked value of native ecosystems: their role in the conservation of widespread species that might be unable to use anthropogenic landscapes in the future. …”
