Evolution of Resistance to Avian Malaria Infection in an Endemic Hawaiian Honeycreeper
Ecology and Evolution, Volume 16, Issue 5, May 2026.Hawaiian honeycreepers, a group of endemic song birds, represent one of the most stunning examples of an adaptive radiation. An evolutionary history devoid of malaria‐causing parasites has made them incredibly susceptible to disease. This work sought to identify genomic correlates of avian malaria infection.

eLife, 2015 Innate pluripotency of mouse embryos transits from naive to primed state as the inner cell mass differentiates into epiblast. In vitro, their counterparts are embryonic (ESCs) and epiblast stem cells (EpiSCs), respectively.

Ecology and Evolution, Volume 16, Issue 5, May 2026.The study investigates genetic divergence among white‐crowned sparrow subspecies across North America, revealing three to four distinct genetic clusters based on genome‐wide SNP analysis, particularly highlighting divergence in the Z chromosome. Notably, Z. l. pugetensis consistently diverges from other populations, and a north–south split within Z. l.

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 345, Issue 4, Page 414-426, May 2026.ABSTRACT With climate change, birds will face increasing thermoregulatory demands, which may alter reproductive behaviors such as offspring provisioning. Experimental studies have shown that the provisioning capacity of female tree swallows (Tachycineta bicolor) is limited by their risk of overheating. Given that parental investment strategies may vary

Aging Cell, Volume 25, Issue 5, May 2026.The steroid hormone ADIOL emerges as a key mediator of fasting–and caloric restriction–induced healthspan benefits in C. elegans. These regimens activate ADIOL production, which acts through the estrogen receptor β homolog NHR‐91 to reduce neural kynurenic acid levels and enhance healthspan independently of lifespan. ADIOL supplementation, even late in

The Ontogeny of Vocal Rhythms in a Non‐Human Primate
Developmental Science, Volume 29, Issue 3, May 2026.ABSTRACT Rhythm is a fundamental aspect of human behaviour, and musical rhythm provides one of its most elaborate instances. Unlike speech, this rhythmic behaviour is characterized by the production of temporal patterns structured around small‐integer ratios, which emerge early in life and change systematically across development.

BMC Genomics, 2009 Background The detection of odorants is mediated by olfactory receptors (ORs). ORs are G-protein coupled receptors that form a remarkably large protein superfamily in vertebrate genomes.

Evidence for the stress-linked immunocompetence handicap hypothesis in humans [PDF]
, 2012 Secondary sexual traits that develop under the action of testosterone, such as masculine human male facial characteristics, have been proposed to signal the strength of the immune system due to the sex hormone's immunosuppressive action.

Evolutionary Applications, Volume 19, Issue 5, May 2026.ABSTRACT Population declines result in increasingly small populations, which often experience an increase in inbreeding. Inbreeding may be negatively associated with fitness traits like survival and reproduction, that is, inbreeding depression, and is therefore detrimental to population persistence and adaptive potential.

Silent Spring - the lost call [PDF]
, 2008 The "silence" in Rachel Carson's Silent Spring1 alludes to the demise of bird populations through reproductive problems and death resulting from exposure to the pesticides of that time, many of which are endocrine active.
