Genes Versus Environment: Body Size Variation Among Recruitment Cohorts of Dungeness CrabNARA Subscribed
Understanding the drivers of phenotypic variation is key to disentangling the evolutionary and environmental forces that shape patterns of trait variation within and among populations. In Dungeness crab, settlement‐stage megalopae exhibit striking seasonal variation in body size, with early season cohorts consistently larger than later ones. This pattern may result from genetically distinct larval sources or environmentally in...
The phylogeny of a person’s hematopoietic stem cells (HSCs) can be used to quantify physiological aging of blood using a phyloAge model based on diversity decay metrics. However, this procedure currently requires accurate HSC genome sequences, which are expensive and time-consuming to obtain. We show that metrics of diversity decay can be derived from the somatic variant frequency spectrum (VFS) using more affordable, routine...
Leading-edge erosion (LEE) of wind-turbine blades, driven primarily by rain erosion, particulate erosion, and environmental ageing, remains one of the most pervasive causes of performance loss and maintenance cost in offshore and onshore wind farms. Self-healing coatings, which autonomously or semi-autonomously restore barriers and mechanical function after damage, promise a paradigm shift in blade protection by combining imme...
What Is a Specialist? Quantifying Host Breadth Enables Impact Prediction for Invasive HerbivoresNARA Subscribed
Herbivores are commonly classified as host specialists or generalists for various purposes, yet the definitions of these terms, and their intermediates, are often imprecise and ambiguous. We quantified host breadth for 240 non‐native, tree‐feeding insects in North America using phylogenetic diversity. We demonstrated that a partitioning of host breadth: (1) causes 67% of non‐native insects to shift from a generalist to special...
Probing the nature of soil organic matterNARA Subscribed
Patients with depression who ruminate repeatedly focus on depressive thoughts; however, there are two cognitive subtypes of rumination, reflection and brooding, each associated with different prognoses. Reflection involves problem-solving and is associated with positive outcomes, whereas brooding involves passive, negative, comparison with other people and is associated with poor outcomes. Rumination has also been related to a...
The bacteria in the Streptococcus bovis / equinus complex (SBEC) and Streptococcus phocae have caused significant morbidity and mortality in northern sea otters ( Enhydra lutris kenyoni ). In order to illuminate the persistence and possible mechanisms of transmission of SBEC and S . phocae , the presence and absence of these bacteria were compared with 31 habitat attributes in Kachemak Bay and Resurrection Bay, Alaska. Bay mus...
