Data from: Addressing incomplete lineage sorting and paralogy in the inference of uncertain salmonid phylogenetic relationships

Matthew Campbell, Thaddaeus Buser, Michael Alfaro & J. Andres Lopez
Recent and continued progress in the scale and sophistication of phylogenetic research has yielded substantial advances in knowledge of the tree of life; however, segments of that tree remain unresolved and continue to produce contradicting or unstable results. These poorly resolved relationships may be the product of methodological shortcomings or of an evolutionary history that did not generate the signal traits needed for its eventual reconstruction. Relationships within the euteleost fish family Salmonidae have proven...

Stress in paradise: effects of elevated corticosterone on immunity and avian malaria resilience in a Hawaiian passerine

Gabrielle Names, Elizabeth Schultz, Jesse Krause, Thomas Hahn, John Wingfield, Molly Heal, Jamie Cornelius, Kirk Klasing & Kathleen Hunt
Vertebrates confronted with challenging environments often experience an increase in circulating glucocorticoids, which result in morphological, physiological, and behavioral changes that promote survival. However, chronically elevated glucocorticoids can suppress immunity, which may increase susceptibility to disease. Since the introduction of avian malaria to Hawaii a century ago, low elevation populations of Hawaii Amakihi (Chlorodrepanis virens) have undergone strong selection by avian malaria and evolved increased resilience (the ability to recover from infection), while populations at...

The core seed mycobiome of P. menziesii var. menziesii across provenances of the Pacific Northwest, USA

Gillian Bergmann & Posy Busby
Fungal symbionts occur in all plant tissues, and many aid their host plants with critical functions, including nutrient acquisition, defense against pathogens, and tolerance of abiotic stress. “Core” taxa in the plant mycobiome, defined as fungi present across individuals, populations, or time, may be particularly crucial to plant survival during the challenging seedling stage. However, studies on core seed fungi are limited to individual sampling sites, raising the question of whether core taxa exist across...
